The error-related negativity is related to risk taking and empathy in young men

We related self-report measures of risk taking and empathy to the error-related negativity (ERN) elicited during a flanker task in boys in late adolescence. We found that risk propensity (risk taking, sensation seeking, and sensitivity to reward) and empathy related to ERN amplitude (negatively and positively, respectively) but not to each other or to behavioral measures of response time, accuracy, and post-error slowing. They accounted for separate sources of variance in the ERN amplitude, suggesting that there are multiple routes to activation of its generator in the anterior cingulate. Impulsivity and sensitivity to punishment were unrelated to the ERN. The present study provides support that risk-taking traits and empathy affect anterior cingulate responsiveness to errors, and the ERN reflects the influence of the extent of individuals' concern with the outcome of events.     

Older people and adherence with medication: a review of the literature

Background

Older people represent a sizeable population of the UK. Many older people receive drug treatment for long-term conditions. Adherence with medication is therefore an important clinical, financial and resource intensive concern.

Objectives

This review aimed to examine patient's beliefs, perceptions and views in relation to adherence with medication.

Design

A comprehensive search of the literature was undertaken using numerous approaches. The search of revealed 30 research papers.

Findings

Articles were initially evaluated using Critical Appraisal Skills Programme principles to identify those relevant to the review. Relevant studies were then subjected to a narrative analysis to assist the development of relevant themes. Four themes were identified; experience of adherence; perceptions and attitudes to medication adherence and non-adherence; patients acceptance of their illness and impact on medication taking behaviour and shared decision making.

Conclusions

The findings of this review imply that there is a need for more emphasis on shared decision making between the older patient and the prescriber. Using this approach, adherence with medication may improve. There is also a need to develop a standardized measure of medication adherence.     

What do general practitioners do differently when consulting with a medical student?

Objectives The practice of having medical students see patients in a general practice setting, in their own consulting rooms, prior to the GP preceptor joining the consultation does not increase general practitioner (GP) consultation time. How do GPs meet the needs of both patient and student without extending consultation time? This study sought to quantify and compare GP consultation activities with and without students. Methods This was a prospective cohort study of 523 videotaped consultations. Consultations were analysed in 15‐second intervals using a modified Davis observation code to define GP activity. Estimated marginal means were calculated using mixed model analysis accounting for confounding factors. Results In comparison with consulting alone, GPs precepting a student spent 37 seconds less time examining patients (P = 0.001), 41 seconds less on patient management, and 1 minute, 31 seconds less on clerical and other activities (P < 0.001). This created time for GPs to take a history from both the student and patient (39 seconds longer; P = 0.002) and to teach students (1 minute, 10 seconds; P < 0.001). Discussion General practitioner activity in the consultation changes significantly when precepting a student; GPs spend longer exploring the history in order to unpack the student’s clinical reasoning, verify the patient’s story and resynthesise the information. They spend less time on examination, management and clerical activities and presumably delegate or defer these activities. Conclusions This organising of clinical activities in order to meet the needs of both patient and student is likely to require different processing skills to solo consulting.     

Post-combat invincibility: violent combat experiences are associated with increased risk-taking propensity following deployment

Combat exposure is associated with increased rates of mental health problems such as post-traumatic stress disorder, depression, and anxiety when Soldiers return home. Another important health consequence of combat exposure involves the potential for increased risk-taking propensity and unsafe behavior among returning service members. Survey responses regarding 37 different combat experiences were collected from 1252 US Army Soldiers immediately upon return home from combat deployment during Operation Iraqi Freedom. A second survey that included the Evaluation of Risks Scale (EVAR) and questions about recent risky behavior was administered to these same Soldiers 3 months after the initial post-deployment survey. Combat experiences were reduced to seven factors using principal components analysis and used to predict post-deployment risk-propensity scores. Although effect sizes were small, specific combat experiences, including greater exposure to violent combat, killing another person, and contact with high levels of human trauma, were predictive of greater risk-taking propensity after homecoming. Greater exposure to these combat experiences was also predictive of actual risk-related behaviors in the preceding month, including more frequent and greater quantities of alcohol use and increased verbal and physical aggression toward others. Exposure to violent combat, human trauma, and having direct responsibility for taking the life of another person may alter an individual's perceived threshold of invincibility and slightly increase the propensity to engage in risky behavior upon returning home after wartime deployment. Findings highlight the importance of education and counseling for returning service members to mitigate the public health consequences of elevated risk-propensity associated with combat exposure.     

Stressor reflections,sleep, and psychological well-being: A pre-registered experimental test of self-distanced versus self-immersed reflections

Evidence supports the effectiveness of cuing people to analyse negative autobiographical experiences from self-distanced rather than self-immersed perspectives. However, the evidence on which this expectation resides is limited largely to static snapshots of mean levels of cognitive and emotional factors. Via a pre-registered, randomised controlled trial (N = 257), we examined the differential effectiveness of self-distanced relative to self-immersed reflections on mean levels and within-person variability of sleep duration and quality as well as psychological well-being over a 5-day working week. Except for sleep quality, we found that reflecting from a psychologically distanced perspective, overall, was no more effective for mean levels and within-person variability of sleep duration, well-being, and stress-related factors than when the current self is fully immersed in the experiential reality of the event. We consider several substantive and methodological considerations (e.g., dosage, salience of stressor event) that require interrogation in future research via experimental and longitudinal observational methods.

Placing dental clinicians within the normative base regarding vicarious response

This paper describes the development and psychometric properties of the Curtin Vicarious Response Scales (CVRS), a research tool specifically developed to evaluate emotional reponsivity in clinical practice and in undergraduate training. The measure yields scores on three substantive scales, (I) Perspective Taking, the capacity to shift perspectives and to step outside of self when dealing with other people, (II) Empathy, the ability to understand another?s mental and emotional states and (III) Emotional Lability, affective sensitivity and changeability. The construct validity of the CVRS is unequivocal and concurrent validation demonstrates its expected place within personality space. The psychometric properties of the device demonstrate its viability as a research tool in the area of Empathy and Emotional Responsivity.     

Risk taking and the triarchic model of psychopathy

Introduction: High risk behaviors, such as aggression, criminality, sexual promiscuity, drug use, and gambling, are often associated with psychopathic traits. Such behaviors might arise due to a lack of fear of the consequences (boldness) or due to impulsive actions (disinhibition). We examined risk taking behavior in the laboratory setting using the Balloon Analogue Risk Task (BART), where an individual can inflate a balloon to earn a reward, but will lose this accumulated reward if the balloon bursts. The task reflects the willingness to take risks under conditions where the risk-taking behavior is understood and is made clear to the individual. Method: BART performance was measured in a mixed community and offender sample, and psychopathy was characterized via the triarchic conceptualization of psychopathy, which proposes that psychopathy is a combination of boldness, meanness, and disinhibition. Results: Total psychopathy score was correlated with greater risk taking on the BART, and this effect was mainly due to the Boldness scale rather than the Meanness or Disinhibition scales. These relationships were not moderated by the nature of the sample (offender vs. community) or by gender. Conclusions: Individuals with high psychopathy scores appear more willing to take risks on this simple laboratory task, and this behavior appears due to boldness rather than being related to an impulsive disposition.     

Effects of positive affect on risk perceptions in adolescence and young adulthood

Affective influences may play a key role in adolescent risk taking, but have rarely been studied. Using an audiovisual method of affect induction, two experimental studies examined the effect of positive affect on risk perceptions in adolescence and young adulthood. Outcomes were risk perceptions regarding drinking alcohol, smoking a cigarette, riding in a car with a drunk driver, getting into a fight, and having unprotected sexual intercourse. Study 1 showed that positive affect led to lower risk perceptions than neutral affect for young adults (mean age 23). Study 2 replicated the effect for early adolescents (mean age 13), mid-adolescents (mean age 17), and young adults (mean age 23). Moreover, Study 2 showed that the effect was most pronounced at high levels of impulsiveness. Adolescents and young adults may be more risk averse in contexts that do not give rise to emotions, but have markedly lower risk perceptions under positive affect.
