Personality and Neural Correlates of Mentalizing Ability

Theory of mind, or mentalizing, defined as the ability to reason about another's mental states, is a crucial psychological function that is disrupted in some forms of psychopathology, but little is known about how individual differences in this ability relate to personality or brain function. One previous study linked mentalizing ability to individual differences in the personality trait Agreeableness. Agreeableness encompasses two major subdimensions: Compassion reflects tendencies toward empathy, prosocial behaviour, and interpersonal concern, whereas Politeness captures tendencies to suppress aggressive and exploitative impulses. We hypothesized that Compassion but not Politeness would be associated with better mentalizing ability. This hypothesis was confirmed in Study 1 (N = 329) using a theory of mind task that required reasoning about the beliefs of fictional characters. Post hoc analyses indicated that the honesty facet of Agreeableness was negatively associated with mentalizing. In Study 2 (N = 217), we examined whether individual differences in mentalizing and related traits were associated with patterns of resting‐state functional connectivity in the brain. Performance on the theory of mind task was significantly associated with patterns of connectivity between the dorsal medial and core subsystems of the default network, consistent with evidence implicating these regions in mentalization.

KNOWING OURSELVES AS EMBODIED,EMBEDDED, AND RELATIONALLY EXTENDED

What does it mean to know oneself, and what is the self that one hopes to know? This article outlines the implications of an embodied understanding of persons and some aspects of the “self” that are generally ignored when thinking about our selves. The Cartesian model of body–soul (or body–mind) dualism reinforces the idea that there is within us a soul, or self, or mind that is our hidden, inner, and real self. Thus, the path to self‐knowledge is introspection. The alternative view is that persons are embodied (entirely physical creatures), embedded (formed by our physical and social environment), and at times extended (cognitively soft‐coupled to artifacts or other persons). This article emphasizes the bodily, active, contextual, relational, often simulated, and sometimes extended nature of the selves that we are, and that we hope to know.     

Using Patient-Reported Outcome Measures for Quality Improvement in Clinical Genetics: an Exploratory Study

International advocacy of patient-centred healthcare delivery has led to emphasis on the (re)design and evaluation of healthcare processes and outcomes from a patient perspective. Patient-reported outcome measures (PROMs) have significant potential to inform such attempts. However there is limited understanding of the processes by which this can be achieved. This exploratory study followed attempts to utilise two different PROMs measures to support service quality improvement in clinical genetics. PROMs used were the Genetic Counseling Outcome Scale (GCOS-24), a well-validated clinical genetics-specific PROM and Euroqol (EQ-5D), a generic PROM favoured by the UK National Institute for Health and Excellence (NICE). Both of these PROMs enable pre/post intervention comparison. A service audit tool was also used, premised on a patient-reported experience measure. In addition, the study draws on interviews with clinical staff to identify challenges associated with the use of PROMs (response rate, data collection, analysis). Benefits are also explored and include the provision of insight into patients’ needs; complementing clinical judgement; identification of needs being met, evidencing the benefit of services provided; prompting consideration of areas requiring attention; and encouraging professional development.     

Performance feedback,self-esteem,and cardiovascular adaptation to recurring stressors

Background and Objectives: This study sought to examine the effects of performance feedback and individual differences in self-esteem on cardiovascular habituation to repeat stress exposure.

Methods: Sixty-six university students (n?=?39 female) completed a self-esteem measure and completed a cardiovascular stress-testing protocol involving repeated exposure to a mental arithmetic task. Cardiovascular functioning was sampled across four phases: resting baseline, initial stress exposure, a recovery period, and repeated stress exposure. Participants were randomly assigned to receive fictional positive feedback, negative feedback, or no feedback following the recovery period.

Results: Negative feedback was associated with a sensitized blood pressure response to a second exposure of the stress task. Positive feedback was associated with decreased cardiovascular and psychological responses to a second exposure. Self-esteem was also found to predict reactivity and this interacted with the type of feedback received.

Conclusions: These findings suggest that negative performance feedback sensitizes cardiovascular reactivity to stress, whereas positive performance feedback increases both cardiovascular and psychological habituation to repeat exposure to stressors. Furthermore, an individual’s self-esteem also appears to influence this process.     

Clinicians' Observations of Family Interactions in the Reunification Process: The Parent Child Checklist

The present article employed a sample of 365 families of children in foster care to conduct a validation test of a newly developed instrument, the Parent Child Checklist (PCC). The PCC is a 54-item direct observation measure assessing parent–child interactions in the context of a family session. The PCC was developed to support the effective implementation of an evidence-based intervention, Parent Management Training-Oregon model, in the Kansas child welfare system. The PCC was designed to capture two scales of child behavior (prosocial and problem behavior) and five parenting domains (encouragement, positive involvement, problem solving, communication skill, and effective discipline). A combination of exploratory and confirmatory factor analysis was used in this first stage validation of the checklist. Results indicated the PCC scales obtained adequate internal consistency and interrater reliability. The confirmatory factor analysis supported 6 of the 7 expected scale domains; however, a two-factor solution was better - supported among the discipline items, labeled as effective and ineffective discipline. Test–retest reliability ranged from 0.45 to 0.80 across child behavior and parenting domains with alpha levels ranging from 0.65 to 0.88. A behavioral observation rating scale for clinicians that is reliable and feasible to implement can represent a significant improvement to practice-as-usual.     

Links Between Stressful Life Events and Proactive and Reactive Functions of Aggression

Recently, more attention has been devoted to understanding how stressful life events might relate to proactive and reactive aggression. Findings suggest that stressful life events are more strongly linked to reactive, than proactive, aggression; however, it is unclear whether the impact of stressful life events on proactive and reactive aggression might vary as a function of the level of exposure to or type of stressful life event. The current study examined how level of exposure to stressful life events (i.e., witnessed, experienced, and learned about) and stressful life event types (i.e., war zone exposure, sexual victimization, interpersonal violence, and other trauma exposure) related to proactive and reactive aggression. The sample was comprised of 500 undergraduate students (M = 18.96, SD = 1.22, 49.6% male) recruited from a Midwestern university. Findings indicated that all three levels of stressful life event exposure (i.e., experienced, witnesses, and learned) were associated with reactive aggression; however, only witnessed stressful life events were associated with proactive aggression. Clinical implications and future directions are discussed.     

Pressure to cooperate: Is positive reward interdependence really needed in cooperative learning?

Background. Despite extensive research on cooperative learning, the debate regarding whether or not its effectiveness depends on positive reward interdependence has not yet found clear evidence. Aims. We tested the hypothesis that positive reward interdependence, as compared to reward independence, enhances cooperative learning only if learners work on a ‘routine task’; if the learners work on a ‘true group task’, positive reward interdependence induces the same level of learning as reward independence. Sample. The study involved 62 psychology students during regular workshops. Method. Students worked on two psychology texts in cooperative dyads for three sessions. The type of task was manipulated through resource interdependence: students worked on either identical (routine task) or complementary (true group task) information. Students expected to be assessed with a Multiple Choice Test (MCT) on the two texts. The MCT assessment type was introduced according to two reward interdependence conditions, either individual (reward independence) or common (positive reward interdependence). A follow‐up individual test took place 4 weeks after the third session of dyadic work to examine individual learning. Results. The predicted interaction between the two types of interdependence was significant, indicating that students learned more with positive reward interdependence than with reward independence when they worked on identical information (routine task), whereas students who worked on complementary information (group task) learned the same with or without reward interdependence. Conclusions. This experiment sheds light on the conditions under which positive reward interdependence enhances cooperative learning, and suggests that creating a real group task allows to avoid the need for positive reward interdependence.     

Reversing the course of forgetting

Forgetting functions were generated for pigeons in a delayed matching-to-sample task, in which accuracy decreased with increasing retention-interval duration. In baseline training with dark retention intervals, accuracy was high overall. Illumination of the experimental chamber by a houselight during the retention interval impaired performance accuracy by increasing the rate of forgetting. In novel conditions, the houselight was lit at the beginning of a retention interval and then turned off partway through the retention interval. Accuracy was low at the beginning of the retention interval and then increased later in the interval. Thus the course of forgetting was reversed. Such a dissociation of forgetting from the passage of time is consistent with an interference account in which attention or stimulus control switches between the remembering task and extraneous events.     

Trait valence and the better-than-average effect

People tend to regard themselves as having superior personality traits compared to their average peer. To test whether this "better-than-average effect" varies with trait valence, participants (N = 154 students) rated both themselves and the average student on traits constituting either positive or negative poles of five trait dimensions. In each case, the better-than-average effect was found, but trait valence had no effect. Results were discussed in terms of Kahneman and Tversky's prospect theory.
