Stressed Men More Likely To Gamble And Takes Risks

Stressed Men More Likely To Gamble And Takes Risks

ScienceDaily (July 1, 2009) — Stressed out, dude? Don’t go to Vegas.

New research, to be published July 1 in the journal PLoS One, shows that men under stress may be more likely to take risks, correlating to such real-life behavior as gambling, smoking, unsafe sex and illegal drug use.

In contrast, stressed women moderate their behavior and may be less likely to make risky choices, the study found.

“Evolutionarily speaking, it’s perhaps more beneficial for men to be aggressive in stressful, high-arousal situations when risk and reward are involved,” said Nichole Lighthall of the University of Southern California Davis School of Gerontology and lead author of the paper. “Applied to financial risk taking, it’s akin to competition for territory or other valuable resources.”

The researchers asked participants to play a game called the Balloon Analogue Risk Task in which inflating a balloon earns money (five cents per pump). Participants were told that they could cash out their earnings by clicking a “Collect $$$” button at any point in the game.

However, the balloon would explode if it was inflated beyond its randomly determined breakpoint. All winnings for exploded balloons would be lost.

“One valuable aspect of the [balloon task] is its predictive validity for real-world impulsivity,” Lighthall explained. “Some risk taking was necessary to make gains, but excessive risk was associated with diminishing returns. If you always clicked and never cashed out, you would lose every time.”

The balloon task has been previously used to assess tolerance for risky behavior among inner-city adolescents and substance abusers, among others.

“Obviously, there are situations in the real world where risky behavior would not be beneficial,” Lighthall said. “Sometimes being conservative, thoughtful and taking it slow are good things.”

In the control group, men and women displayed statistically similar levels of risk taking, inflating the balloon about 40 times on average.

However, women in the stressed group only inflated the balloon an average of 32 times – more than 30 percent less often than their stressed male counterparts, who inflated the balloon an average of 48 times.

“Men seem to enter more risky financial situations than women, which was part of the impetus for our study,” Lighthall said. “But only in the stressed condition did we see any statistical differences in risky behavior between men and women.”

Stressful experiences have been shown to stimulate the release of cortisol, commonly known as the “stress hormone.” Participants randomly assigned to the stress group held a hand in ice-cold water, which raised cortisol levels, particularly among female participants. No participants were using hormone birth control.

According to Lighthall, future research might use neuroimaging to explore how the brain processes stress or examine whether psychological stress, such as anticipating giving a speech, would yield similar results as the physical stress manipulation used in this study.

Mara Mather, director of the Emotion and Cognition Lab at USC and associate professor of psychology and gerontology at the USC Davis School of Gerontology, and Marissa Gorlick, also of the USC Davis School of Gerontology, were co-authors of the study.

Trust ’sorry’ for murders by patients in its care

• Reports criticise Humber mental health trust for failure of care
• Mother of five and elderly woman died in separate incidents

* Sam Jones
* guardian.co.uk, Wednesday 6 May 2009 00.30 BST

A mental health trust has apologised to the family of a pregnant woman who was killed by a paranoid schizophrenic man, and to the relatives of an 82-year-old woman who died at the hands of her mentally ill son.

New reports into both cases have criticised Humber mental health teaching NHS trust for failing to provide better care for the two men.

Tina Stevenson, a 31-year-old mother of five, was on her way home from an ante-natal class in Hull on 5 January 2005 when she passed Benjamin Holiday. The 25-year-old man, who had missed his medication the day before, stabbed Stevenson in the back. Neither she nor her unborn twin boys could be saved.

Holiday admitted manslaughter during his trial in May 2006 and was ordered to be detained indefinitely at a secure mental hospital.

An independent report into his care and treatment published by NHS Yorkshire and Humber concluded he had been “under-treated” by the trust.

Holiday, who had been suffering mental health problems since 2001, spent a fortnight in a secure unit in 2004 but was later discharged and treated in the community. The report admitted that Holiday, whom it referred to as “B”, was a difficult patient to engage with and was skilled at masking his symptoms.

It concluded: “The root cause contributing to B’s continuing severe mental disorder was that of ‘under treatment’. B’s situation and condition could and should have been more assertively managed.”

The chief executive of the Humber trust, David Snowden, apologised to those affected by the case and promised lessons would be learnt. He said his trust “fully accepted the recommendations, which we are taking very seriously”.

The trust also apologised to the family of Ivy Torrie, 82, who was killed by her mentally ill son, Michael, in Pocklington, East Yorkshire, in 2003.

A separate report attributed Michael Torrie’s actions to the “rapid reduction of medication and the way this was managed in the absence of a risk assessment”.

Marjorie Wallace, chief executive of the mental health charity Sane, said that although such events were rare, they did not “come out of the blue”.

“It is not an expensive revolution in care we need but common sense,” she said. “You do not leave an 82-year-old mother alone to care for her mentally ill son whose medication has been radically changed, with no support.

“Nor do you allow someone who may be becoming severely disturbed to dictate their own care and treatment without rigorous assessment of the risk they may pose to themselves or others.

“We have had 15 years of independent inquiries all exposing the same fault lines in the care and treatment of people with serious mental illness.”

Mental health and offending: One man’s prison experience

A new report today by Lord Keith Bradley says offenders with mental health problems are being failed by the criminal justice system. David Smith, who suffers from schizoaffective disorder, explains why prison wasn’t the right place for him

* Mary O’Hara
* guardian.co.uk, Thursday 30 April 2009 16.47 BST

Like many people who run up against the criminal justice system while dealing with a serious mental health condition, David Smith [not his real name] felt that neither the police nor the prison service were equipped to deal with him. Smith has schizoaffective disorder. He manages his condition with fortnightly injections but in early 2008 he missed a series of appointments for medication, and became unwell.

By April his symptoms returned. These included hearing voices. David went to speak to his mother, with whom he had a fraught relationship, about his problems but the encounter turned into a confrontation that frightened her. At 2am the police arrested him on suspicion of common assault. He was locked in police cells for four days.

When he finally went to court they asked for a psychiatric report. The judge recommended that Smith receive hospital treatment but in the absence of a bed in a secure mental health unit Smith was instead sent to Wormwood Scrubs prison and spent a total of four months there.

“I have difficulty remembering my appointments; I never intend to miss any, I just find it difficult to remember when they are,” David says, explaining his state of mind at the time of his arrest. “My regular CPN [community psychiatric nurse] understands this and she gives me a ring the day before to remind me. When she went on leave I got a new CPN. He knew I couldn’t remember my appointments but he wouldn’t ring me with a reminder.

“I must have missed more than one injection,” he concludes. “My friends tell me there’s a pattern when I’m getting unwell. My symptoms came back and when I was at home one day I heard my mum screaming, ‘I’m going to kill myself’. I went to speak to her. I tried to talk to her. Mum just got frightened. I didn’t get anywhere with her so I went home.”

When he was arrested, Smith says, he did his best to explain himself to police officers but what happened was unsettling and frustrating. He recalls: “At the station another police officer asked me exactly the same questions; they didn’t look at any of the notes that had been taken. The policeman was trying to wind me up. I was so pissed off, I just said ‘yeah, whatever’ and sat down. They knew I had a mental illness as my mum phoned the hospital before she phoned the police. I was interviewed and put in a cell for four days. When I went to court the solicitor explained about my condition. One of the first things they said was that they needed a psychiatric report. Then the judge said I should be in hospital but there weren’t any secure beds so I went straight to Scrubs.

“When I got there I was very unwell but I didn’t know I was so I told them I didn’t have a mental illness and they put me on a general prison wing. They did put me in a single cell so I guess they had my [medical] notes. On my first day someone took the TV out of my cell. I thought to myself they’ll take anything, so I sat in my cell for two weeks. For those two weeks I was probably getting worse, more unwell. No one noticed, they [the prison] haven’t got the staff to notice.”

After throwing a chair and wardens intervening because his behaviour became so erratic, Smith was put in the hospital wing of the prison but was soon transferred back into the general prison population.

He reacted by throwing a chair.

“I spent the last two months in the general wing. I was well then. I talked to staff a lot. They were good to me. When I’m well I’m very polite so I was no trouble.”

Smith says that most of all he felt unlistened to, as if what he was going through was misinterpreted and that the prison wasn’t equipped to deal with his problems. He decided to write to a judge to see if he could get his point of view across.

“I wanted the judge to know what happened from my point of view. I felt I hadn’t been heard in court,” he explains. “Everyone talked about me and not to me. I wanted to say I was sorry. My case came up again and the judge said that I had clearly stabilised, I understood what had happened and that I had already served the time I would have done on a guilty plea while waiting for a bed in a secure hospital so I could go.”

Prison life is simply not the right environment for people like himself, Smith believes.

“If you can handle yourself when in prison you’re OK, if not it’s all over,” he says. “I managed but I met guys who came in after me and they tried to commit suicide or burn down their cells. It’s a 23-hour lock down. I spent most of my time pacing in my cell. I can still remember the pattern my pacing took, the same one over and over again. I never want to go back. I’m doing everything in my power not to go back. I’m keeping myself busy.”

Man has admitted killing Philip Ellison, the Lancashire Council social care worker

Posted: 24 April 2009 | Community Care
A man has admitted killing Philip Ellison, the Lancashire Council social care worker stabbed to death during a visit to a supported housing project. Robert Searle, 52, was detained indefinitely under the Mental Health Act after pleading guilty to manslaughter at Preston Crown Court today. The Recorder of Preston, Anthony Russell, ordered the detention of Searle at Ashworth Hospital, a high-security institution in Merseyside.

Ellison, a married father of three, was 47 when he was attacked at the supported living scheme in Glebe Road, Preston, in April 2008. Article continues below the advertisement

An internal review into the incident by council officers and Lancashire Care Foundation Trust is expected to be published after Searle is sentenced. Anne Brown, cabinet member for adult and community services at Lancashire Council, said today: “The death of Philip in April last year was an extremely sad and tragic incident that has deeply shocked the county council, the local community and the social care sector immeasurably.

“Although the incident happened almost a year ago we, as an organisation, are still trying to come to terms with the loss of Philip who was a professional social care worker, a valued and respected member of staff and dedicated wholeheartedly to supporting people. “On behalf of the county council, I would like to offer our sympathy to Philip’s wife and sons who have lost a loving husband and father, and to his friends and colleagues – our thoughts are with them, particularly at this very difficult time.”

This week, it emerged that Sunderland charity Mental Health Matters, will be prosecuted under health and safety laws over the death of Ashleigh Ewing. The 22-year-old care worker was stabbed to death in 2006 while visiting a client with mental health problems. Searle was originally charged with murder, but the prosecution accepted a plea of manslaughter on the grounds of diminished responsibility.

Training Curbs Anger And Aggression In Adolescents With Tourette Syndrome

Article Date: 24 Apr 2009
In the first study to gauge the benefits of anger control training in adolescents with Tourette syndrome (TS), researchers at the Yale Child Study Center have found that cognitive behavioral therapy is helpful for short-term improvement in anger and aggression. The study is reported in the April issue of the Journal of the American Academy of Child and Adolescent Psychiatry. Children and adolescents with TS, a disorder characterized by tics-involuntary, rapid, sudden movements and vocalizations occurring repeatedly in the same way-should also be evaluated for the presence of disruptive behavior problems, according to lead author Denis Sukhodolsky, associate research scientist in the Yale Child Study Center. “In some cases, these disruptive behavior problems can cause more impairment than tics,” he said. “If disruptive behavior is present, cognitive behavioral interventions such as anger control training could be recommended to reduce the levels of aggression.” Sukhodolsky and his team studied 26 children and adolescents with TS (24 boys and two girls between the ages and 11 and 15) with moderate to severe levels of oppositional and defiant behavior. They were randomly assigned to a group that received 10 sessions of anger management or to a control group that received their usual treatment for 10 weeks. When faced with frustrating situations during anger control training, the children role-played appropriate behavior. They were asked to identify and evaluate the consequences of various actions for themselves and others who were involved in hypothetical conflicts. The children were also asked to recall frustrating situations and to problem-solve and role play behavior that would have diffused the problem. They also completed homework to practice “anger coping” skills and share their experiences at the next session. At the end of treatment, parents reported that disruptive behavior decreased by 52 percent in the anger management group, compared with a decrease of 11 percent in the control group. Clinicians who were unaware of the treatment rated 69 percent of the children who completed anger management training as improved compared with 15 percent in the control group. Sukhodolsky said this improvement was well maintained at a three-month follow-up. He and colleagues plan to conduct larger clinical trials to confirm their results. The study is part of a clinical research program directed by Professor Lawrence Scahill to develop and test interventions for children and adolescents.

Step-fathers who Kill

Lurking in the shadows

Posted: 09 April 2009 | Community Care Magazine http://www.communitycare.co.uk/Articles/2009/04/09/111233/lurking-in-the-shadows.html

Maria Colwell. Jasmine Beckford. Heidi Koseda. Kimberley Carlile. Leanne White. Lauren Creed. Baby P. These names don’t resonate only with social workers; as some of the UK’s most notorious child deaths they conjure up grim details that are etched on the nation’s collective memory.

And they have something else in common: they all died at their stepfather’s hands. In many cases their mothers received prison sentences for offences ranging from neglect to assault or manslaughter.

Sadly, these are just a few names on the deathly roll call that stretches back to 1973 of young children killed by their stepfather or their mother’s boyfriend.

No matter how good our protective or preventive measures, there will always be parents who will harm or even kill their children. Whether the killer is their biological father or their stepfather may not seem that relevant when it comes to informing preventive policies, but research suggests otherwise.

In 1988, US data showed that children aged up to two are at about 100 times greater risk of being killed by their stepfather than their biological father. Psychologists call this the Cinderella effect. The research went on to look at British data, concluding that it indicated “considerable excess risk at the hands of stepfathers”.

With the rates of remarriage, divorce and cohabitation steadily increasing, giving rise to more stepfamilies, this is a disturbing thought. According to the Office of National Statistics, in 2006 84% of stepfamilies consisted of a stepfather and biological mother living with children from her previous relationship.

Research suggests that whereas genetic fathers often kill their children “more in sorrow than in anger”, out of perceived necessity and/or as part of a suicide, homicides committed by stepfathers tend to be more rage driven, impulsive acts motivated by hostility towards the child and characterised by violently beating or shaking them.

Despite this evidence, some researchers believe that minimal attention has been given to stepfathers – or mothers’ boyfriends – as the perpetrators of these crimes and the reasons behind them.

David Finkelhor, director of the Crimes Against Children Research Center in the US, says: “Sociobiologists point out that these are men who have no genetic stake in this child and see them as competition for attention and time, and their own offspring. Among other primates it’s not unknown for a new alpha male to kill the children of the dominant male when he comes into a group.”

But Finkelhor believes the reasons are simpler than that. “That has some reality to it, but I think it operates through more familiar psychological mechanisms; that these aren’t men who feel a natural affinity or protectiveness about the children of the women they are involved with. These are not men who are nurturing.”

Anger management

This squares with the fact that a child’s inconsolable crying is one of the main triggers for these homicides. “Frequently the dynamics of these cases are common,” says Finkelhor. “The woman leaves the child with the boyfriend or stepfather and when the child starts crying, he doesn’t have the nurturing skills to handle this in a calm way and then hits, throws, or smothers them because he wants them to shut up.

“They are not all of one sort, but a high proportion [in these cases] are violent, abuse their partners, and tend to have an anger management problem.”

Gathering any deeper psychological profile of these men is hampered by the fact that we know so little about them, and what we do know is usually learned after a child has been killed – which isn’t helped by serious case reviews that mostly focus on the pathology of the mother.

This reflects the continuing failure of agencies to engage properly with men, says David Derbyshire, Action for Children’s head of performance improvement and consultancy, and author of several serious case reviews.

“We probably don’t know a lot because too many times we come across cases where there is no involvement with men. Then there is an incident where the child is injured or dies, the serious case review takes place and we see the intervention is often only all with the woman and the man is not known about, or if he is, there’s no contact.

“If you don’t engage with the man but he is there everyday then the work we are doing is going to have a limited impact.”

Before we can even reach a position where men are properly involved, social workers need to recognise their importance to the whole familial picture and approach them with an open mind, which appears to happen too infrequently.

Research for a book he was writing on gender and child protection led says Jonathan Scourfield, senior lecturer at Cardiff University’s school of social sciences, to interview social workers about how they worked, or didn’t work, with men. He found primarily pejorative views.

“Men were seen as a threat, as no use, as irrelevant and absent – and there was a whole host of reasons given for not engaging with them.”

The dominant theme was of men as a threat, not surprisingly given the kinds of problems that caused referrals to be made to the team. But what worried Scourfield was the number of men that social workers didn’t pick up on. “Often there’s a boyfriend, the mother doesn’t mention it, but he’s hovering in the background, half noticed.”

Even if he is seen or known about, it’s all too common for no real attempt to be made to engage him. “The social work culture is an important part of that, but there’s a huge issue with the actual behaviour of these men. We are talking about men who are very difficult to work with and that needs to be acknowledged,” Scourfield adds.

This leads to questions of how a social worker can confidently decide whether to engage with the individual, or whether they are so dangerous they should be removed from the child’s life. It’s a dilemma that troubles Brid Featherstone, professor of social work and social policy at Bradford University: “We haven’t equipped social workers to work with these men. We haven’t got skills in assessing men generally, so we don’t even get as far as deciding that this man shouldn’t be in the family home.

“There is a problematic absence of an evidence base in the UK about working with men – either those who are a resource for children or a risk. Half the time we don’t know who is in a family. We don’t even record birthfathers if they are not there so how are we going to find others floating around? We tend to rely on the mother but it can be hard to establish living arrangements, as we can see in the Baby P case.”

The need for evidence

Jack Kennedy understands these difficulties. As a consultant in clinical and forensic psychology he compiles psychological reports for courts and parole boards and has worked on some of the most well-known child death cases. “Social workers have a very difficult job because they need evidence to act,” he says. “But it’s very difficult to anticipate or intervene unless there are overt indicators of risk or harm. Society almost expects [social workers] to be a ministry of pre-crime and intervene before these events happen, but to go in and remove a child on a suspicion won’t hold up in court.”

Other than obvious danger signs such as known domestic violence or injuries on a child, Kennedy suggests that where social services are involved with a family they need to be aware of mothers developing new relationships and people visiting the home. “Not least because it can be destabilising for the child having different people coming into the home. And also because they can assist a mother in actively risk managing all the time. But there is a thin line between policing and social care.”

However, any information social workers pull together often comes from the mother and therefore relies on her being honest. This is unlikely to happen if she is witness to her partner abusing her child but feels powerless to do anything about it.

While most of us would find this thought process hard to fathom, the issues behind this “collusion” can be complicated. The personality of these women can form part of the equation. Research into these deaths shows that many women lived in fear of their partners and that violence and abuse against a partner and child often coexisted.

These women can be depressed, overwhelmed or so distracted by their own difficulties that they don’t feel capable of doing anything. Women who are desperate to keep a partner will placate them, or those who are so intimidated by a partner won’t stand up to them.

“These are usually highly vulnerable women who have a confused understanding of relationships,” says Kennedy. “Their backgrounds are characterised by abuse and they are highly dependent on being in a relationship even if it’s dysfunctional because that provides them with the security they are looking for. Many women prize the man they have highly because they believe themselves to be loved in some way. Love and affection become more important to them than the needs of the child.

“They are not resilient enough to say ‘that is wrong, this is over,’ because they think they will not get anyone else. This is not about excusing their behaviour, it’s about helping us understand more about what sort of situation an individual may be in.”

Featherstone goes further, saying there are women who are terrified, and other more complex women who don’t acknowledge their ambivalence to their child. “We are hamstrung by the assumption that all mothers love their children or, if they don’t, they can be helped to. But we have to acknowledge maternal ambivalence. Hate can become the more dominant feeling. I have worked with a small number of women who were sadistic themselves. While you are not going to get lots of these women, sometimes you have to think the unthinkable.”

In 2007-8 there were 45 homicides of children aged up to four, according to the Home Office. But these figures don’t include death by neglect or cases which, although were not classified as murder, were not accidents either. Some analysts in the US believe that, there, the actual figure for child homicides may be double the official one because they can resemble deaths resulting from accidents or other causes; for example, a child who has been thrown or intentionally dropped will have similar injuries to those of one who died after an accidental fall.

The so-called Cinderella effect has no fairytale solution. Evidence of the prevalence of deaths caused by stepfathers is there, though the connection is not always made. But we owe it to the memories of all those children from Maria Colwell to Baby P to make sure we know who is present in a child’s life and whether they are a resource or a risk, so we can prevent as many children as possible from ending up on the same list.

Mentally Disordered More Likely To Become Victims Of Violence When Showing Increased Symptoms

Article Date: 16 Apr 2009 – 0:00 PDT

Contrary to common stereotypes, individuals with major mental disorders are more likely to become victims of violent crimes when they are experiencing an increase in symptoms than they are to commit crime, according to a new study by Brent Teasdale, an assistant professor of criminal justice at Georgia State University.

Teasdale found that patients experiencing delusions, hallucinations and worsening symptoms generally are most likely to become victims of violence. In addition, individuals with mental disorders are particularly vulnerable for victimization during times of homelessness and when suffering from alcohol abuse.

“They actually have higher rates of victimization than they have of violence commission, which I think is counter to the stereotype that highly symptomatic, obviously delusional, visibly mentally disordered people are dangerous, unpredictable and violent,” Teasdale said. “There’s no one size fits all approach to these delusions, but the odds of victimization are multiplied almost by a factor of two when a person experiences these delusions.”

Teasdale analyzed data from the MacArthur Violence Risk Assessment Study, a longitudinal study of psychiatric patients released from three psychiatric hospitals in Pittsburgh, Pa., Kansas City, Mo., and Worchester, Mass. During the MacArthur study, participants were interviewed every 10 weeks for one year about violence committed against them, stress, symptoms and social relationships.

When individuals with mental disorders experience increases in delusions, symptom severity and alcohol problems they may be more focused on their internal states and have fewer cognitive resources available to devote to interactions with other people, Teasdale said. Other research suggests that victimization happens because caretakers may be driven away, leaving the disordered unprotected.

“If the stigma is that those are people we need to protect ourselves from, one of the ways in which we might do that is self defensive violence. We might strike first and that would lead to the victimization of these folks,” Teasdale said. “If there’s a person that could intercede before that happens, that may be one strategy for reducing victimization risk.”

The findings of the study are important for clinicians who must pay attention to warning signs of worsening disorders as potential risk markers for violent behavior committed by their client, Teasdale said. They could also aid in the creation of assessment tools that focus on victimization risk and classes that better educate families about caring for the mentally ill.

Clinicians also could provide clients suggestions for reducing victimization risk when they notice patients exhibiting greater than usual symptoms, Teasdale said. For instance, during these times clinicians may recommend spending less time in public spaces, increases in guardianship or mandated community treatment programs.

“Most of us know people who have mental disorders. These are our family members and our friends and so we should care about their victimization experience,” Teasdale said. “The stereotypes persist because people are unaware of the victimization risk to people with mental illness. If they learned that victimization risk were higher than the violence commission rates, I think that would help alleviate some of that stigma and help people think about people with mental disorders in a different way.”

Notes:

The study, “Mental Disorder and Violent Victimization,” was published in the 2009 edition of Criminal Justice and Behavior.

New Imaging Research Reveals Dysfunction In The Brain’s “Hub” In The Earliest Stages Of Schizophrenia

Although the following article is not new, I’m putting it up in response to some enquiries relating to the thalamus and hallucinations. Happy reading! Iain Bourne

ScienceDaily (Jan. 1, 2001) — A new brain imaging study from the Institute of Psychiatry shows for the first time that the thalamus, the brain’s main sensory filter or ‘hub’, is smaller than normal from the earliest stages of schizophrenia. The findings, published in the American Journal of Psychiatry in January, may explain why people with schizophrenia experience confusion during their illness. The thalamus is the area where information is received and relayed to other areas of the brain. It is of particular interest in schizophrenia because of the role it plays in processing information. The thalamus receives information via the senses, which is then filtered and passed to the correct regions of the brain for processing. People with schizophrenia often have difficulties in processing information properly and as a result may end up with an information overload in some areas of the brain. This study, led by Dr Tonmoy Sharma, involved 67 participants: 38 were experiencing their first episode of psychosis and 29 were healthy volunteers. In contrast to other studies, thirteen of the people with schizophrenia had no or little experience of antipsychotic medication. Magnetic resonance imaging (MRI) scans identified differences in the thalamus between the two groups. Previous MRI studies have identified several brain regions affected by schizophrenia, but the results in the thalamus have been inconclusive. This study finds that even in the earliest stages of schizophrenia the thalamus is smaller than in healthy people. Dr Tonmoy Sharma said: “This study reveals that there is a fundamental problem in the hub of the brain. If you think of the brain in terms of networks, it is like making a phone call when the line is not connected properly, the call can’t be made, or you may get through to the wrong person. It is the same in the brain. If there are problems with the connections, information will not be passed to the correct regions. The ability to filter and process information is vital for leading a normal life.” These findings, along with a recent study from Dr Sharma’s team that showed people with schizophrenia have decreased grey matter at the earliest stages of the illness suggest a role for brain imaging in pinpointing warning signs of the illness and even preventing its development.

Police With Higher Multitasking Abilities Less Likely To Shoot Unarmed Persons

ScienceDaily (Apr. 1, 2009) — In the midst of life-threatening situations requiring split-second decisions, police officers with a higher ability to multitask are less likely to shoot unarmed persons when feeling threatened during video simulations, a new Georgia State University study suggests.

Heather Kleider, Dominic Parrott and Tricia King, assistant professors of psychology at Georgia State, have taken a unique look at officer-involved shooting situations, signs of negative emotions and working memory capacity — the capacity to perform multiple mental tasks, such as reasoning, at the same time.

Other studies have examined factors such as ethnicity, stereotypes, neighborhood crime rates and other factors, but this study examines the effects of police officers’ characteristics on shooting decisions.

“In cognitive psychology, operation span, or working memory, is an overarching cognitive mechanism that indicates the ability to multitask, and the amount of available capacity to perform tasks varies by individual and situation,” Kleider said. “People with a higher capacity are able to keep more things ‘in play’ at one time.”

Urban police officers participated in the study, completing a test of working memory capacity, and then watched a video of an officer-involved shooting that resulted in the death of the officer, during which time negative affect and stress indicators were measured; including elevated heart rates and increased sweating.

Following the video, officers participated in a computer-based simulation where they were required to make split-second decisions whether to shoot or not to shoot someone, based on 80 slides that presented a person holding either a gun or a harmless object like a cell phone, for only a fraction of a second. Officers then pressed either a “shoot” or a “don’t shoot” button.

Analyzing the data, the researchers found that lower levels of working memory capacity increased the likelihood of shooting unarmed people among those officers who had higher levels of negative emotionality — a score determined by comparing readings of facial movement and heartbeat rates between a baseline reading and readings taken during the stressful situation.

Officers with a higher working memory capacity seemed to buffer officers against the negative effects of a threat when making shooting decisions.

“An important thing to consider is that some decision making requires controlled processing wherein balanced/accurate decisions require impulse control” Kleider explained. “For some people, this usurps a substantial amount of available working memory capacity to control impulses, and if you are someone with a lower capacity, it’s harder to do.”

Psychologists are not sure whether working memory capacity can be increased with training, but Kleider and her colleagues are planning to investigate this, and are also planning to work with several police departments on a broader study to see if training and years of experience influence shooting decisions.

64% Of Medical Professionals Are Subject To Insults And Threats

Researchers from the University of Zaragoza have studied violence suffered by medical professionals whilst carrying out their profession. The data show that 11% of doctors have been victims of physical aggression and 5% have been subject to this on more than one occasion, whereas 64% of medical professionals are subjected to threats, coercion and insults.

Until a few years ago the only knowledge regarding aggressive activities in hospitals concerned extreme cases. The study entitled “Analysis of Violence”, undertaken in 2005, provided the first results a year later. Now, this article deals with differences according to the type of centre, area and profession and informs us about the real incidence of this problem in Spain.

“The reality is that there is a less serious, insidious and continued violence of physical aggression, threatening behaviour and verbal abuse that is not reported as this is considered less important, but this type of violence can damage the health of the professionals and the quality of healthcare”, explains Santiago Gascón to SINC, who is the principal author of the study. The study has been undertaken together with Begoña Martínez-Jarreta and other researchers from the University of Zaragoza (UNIZAR).

The results, which are published in the latest number of the International Journal of Occupational and Environmental Health, shown that 11% of the professionals have been the victim of physical aggression and 5% have been subjected to this on more than one occasion, whereas 64% have been subjected to threatening behaviour, coercion and insults. 34,4% have suffered threats and coercion on at least one occasion and 23.8% on numerous occasions. Similarly, 36.6% have been subjected to insults on one occasion, at least.

The work, which was undertaken during 2005 in three hospitals and 22 primary care centres in rural and urban areas in Aragón and Castilla-La Mancha, analyses the experiences and identifies the variables implicated, their distribution according to service, profession, age and gender, as well as the possible association between the number and severity of incidents and psychological health problems.

Among 1,845 participants in the research, 64,2% were women and 35,8% were men, and the mean age was 42.8 years. According to profession the proportion was as follows: 33.5% were doctors, 47.5% were nursing professionals, 7.9% were administrative personnel, 1.7% were from management, 2.8% were porters and 6.6.% were technical personnel and other professionals.

The figures are higher in the large hospitals compared to the small centres and reach very high values in services such as Accident and Emergency and Psychiatry. According to Gascón, “the data show the true dimension of under-reported violence”.

Violence due to waiting time

The study shows, moreover, that 85% of cases of aggression are perpetrated by the patients themselves (this percentage is lower in the Accident and Emergency Service where 27.3% of the aggressors turn out to be the people accompanying the patient). 21% of the aggressors are affected by a psychiatric disorder and cognitive deterioration and 5.7% are under the influence of alcohol or drugs.

The most frequent reason for aggression is related to waiting time (58%), followed by disagreements over the issuing of a doctor’s certificate (15%) or the prescription of medication (10%).

But the data contrast with the fact that only eight professionals in this study actually reported the aggression (all were serious physical injuries) whereas there were no reports for episodes of threats of insults.

“Taking into account that the proportion of women in the healthcare environment usually exceeds 60%, no relationship was observed between physical aggression and the fact that the victim was a man or a woman; but this did occur in the threats variable, with a clear prevalence of male victims and who were higher up in the hierarchy”, the researcher from Zaragoza points out to SINC.

Both physical and psychological violence show an identical negative impact in terms of burnout (work dissatisfaction). The perceived support is a variable which protects against the psychological effect of aggression, in such a way that those who do not feel supported by the administration show a worse prognosis following a violent episode.

“Professionals complain about the fact that the legislation in the different communities does not give the same attention to the rights of the professional as they do to the rights of the patient and that, among the responsibilities and duties of the patient, it states that they must show respect to the equipment and property in the centres, but not one single line mentions observing respect for the dignity of the person who is caring for them”, concludes Gascón.
