The backlash of token mobility: the impact of past group experiences on individual ambition and effort

Two studies investigated the impact of past ingroup experiences on individual aspirations and effort. Participants were told that in the past, members of their group had either been offered no opportunities (closed), few opportunities (token), or equal opportunities (open) to achieve a desired outcome. The results show that past group experiences determine responses to current opportunities and affect the perceived feasibility of individual success as well as individual performance. Exposure to a token system has different effects, depending on whether the group is historically advantaged or disadvantaged. Whereas those with a collective history of success see token mobility as a challenge and show superior performance, the same situation constitutes a threat to members of a historically disadvantaged group, who fail to take advantage of the opportunities offered to them and perform suboptimally.     

Differential effects of physical and psychological stressors on immune functions of rats

To study the effects of different types or durations of stressors on immune functions, male Fischer rats were exposed to chronic physical (electric foot shock) or psychological (non-foot shock) stress induced in the communication box. Superoxide production by alveolar macrophages (AMs), mitogen-induced splenic lymphocyte proliferation, and splenic natural killer (NK) cell cytolysis were examined in vitro. Repeated exposure to physical stress suppressed superoxide production by AMs (-58%, p<0.05 for opsonized zymosan (OZ) and -51%, p<0.05 for phorbol 12-myristate 13-acetate (PMA)), although psychological stress suppressed superoxide production after 24 h of repeated exposures (-40%, p<0.05 for OZ and -47%, p<0.05 for PMA). Acute suppression of the blastic response of splenic lymphocytes was only found in the physical stress group (p<0.05), although the chronic effects were only found in the psychological stress group (p<0.05). NK cell activity was suppressed immediately after the acute physical stress (-30%, p<0.05), but no effects were found in the psychological stress group. These results underline the importance of distinguishing between physical versus psychological stressors when examining the effects of stress on immune functions.     

Line segments are perceived better in a coherent context than alone: An object-line effect in visual perception

In a series of four experiments, observers identified a briefly flashed line segment more accurately when it was part of a drawing that looked unitary and three-dimensional than when the line segment was presented alone. This extends earlier findings of better identification of a line segment when it is part of an apparently unitary, three-dimensional drawing than when it is in a less coherent flat design; and these results demonstrate a visua1 effect analogous to the word-letter effect which uses nonlinguistic materials. Experiment 1 demonstrates the existence of the object-line effect and shows that it does not depend on the presence of a subsequent mask; Experiment 2 shows that the effect holds up with two-altemative forcedchoice presentation; Experiment 3 demonstrates that the effect is not due to bright end points which may occur when the target line appears with a context; and Experiment 4 shows that the effect is as strong when the target line segments occupy widely separated spatial locations as it is when they occupy nearby, potentially confusable locations.     

Addressing social determinants of mental health in therapy: A thematic synthesis

Background

The importance of addressing social determinants of mental health in therapy is well-documented. However, there appears to be limited research on what this actually involves in practice and how best to prepare therapists to work with individuals experiencing adverse social determinants.

Aims

The aim of this review was to draw implications for practice and training from reviewing research on addressing social determinants of mental health in therapy.

Methodology

A qualitative systematic review of the research on addressing social determinants of mental health in therapy was conducted, extracting papers from eight databases: Cochrane Library, ASSIA, CINAHL Plus, PsycInfo, Psychoanalytic Electronic Publishing, Science Direct, Scopus and Web of Science. Out of 127 papers found, five met the eligibility criteria and were quality-assessed and analysed thematically.

Findings

The thematic synthesis generated three main themes: “the therapeutic relationship,” “adapting to client context” and “community as a resource,” with eight subthemes.

Conclusion

This thematic synthesis highlights the importance of the therapeutic relationship and adapting mental health support to client frame of reference and context to address social determinants of mental health in therapy. It emphasises community as a helpful resource for informing training and therapeutic interventions, as well as a significant resource for people experiencing adverse social determinants.     

Combining whole-school and targeted programs for the reduction of bullying victimization: A randomized,effectiveness trial

Despite the extensive evaluation of school-based interventions for bullying, victimization remains a significant problem in schools. Bullying victimization is significantly predicted by contextual (school-related) factors. As a consequence whole-school programs have been commonly used to prevent and reduce bullying victimization. Evidence also points to individual risk factors (such as emotional distress) in predicting victimization, yet programs to prevent bullying victimization by changing these individual risks are far less developed. Few studies have approximated “real-world” implementation conditions in their trials. The current effectiveness trial evaluated the combination of a whole-school program designed to prevent bullying perpetration and victimization together with a targeted intervention for at-risk students, teaching them individual and dyadic strategies to reduce their anxiety and manage victimization, allowing schools some latitude to implement programs as they typically would. Students from Grades 3 and 4 (N = 8,732) across 135 schools were randomly assigned to one of four conditions: combined intervention; whole-school intervention only; individual intervention only; and care as usual. Victimization decreased significantly and similarly across all four conditions at 12 and 24 months following baseline. Similar reductions and failure to discriminate conditions were found on other key constructs: anxiety; bullying perpetration; and depression. Possible reasons for the failure to demonstrate victimization prevention differences and lessons learned from this large, effectiveness trial are considered.     

Review of three tests of motor proficiency in children

The present purpose is to provide clinicians, occupational and physical therapists, and educators with a comparative analysis of three tests of motor proficiency. The Bruininks-Oseretsky Test of Motor Proficiency, Movement Assessment Battery for Children, and Tufts Assessment of Motor Performance were developed to assess the motor skills of children with developmental delays. The selection criteria, interrater reliability, reproducibility, and recommended use of each test are reported here. Recommendations for use of each test include standardization of the sample population to ensure its appropriateness.     

Influence of Deteriorating Ability of Emotional Comprehension on Interpersonal Behavior in Alzheimer-Type Dementia

This study investigated the relationship between the ability to recognize emotion and interpersonal behavior in dementia of the Alzheimer type (DAT). After examining the validity and reliability of the Emotion Recognition Test (ERT), an improved version of the tasks used by Shimokawa et al. (2000), 100 patients with DAT underwent evaluation for general cognition using the Mini-Mental State Examination (MMSE) and emotion recognition using the ERT. Within a week of these tests being administered, ward staff rated the patients using the Interpersonal Behavior Checklist (IBC), composed of two behavior scales: indifference to interpersonal relationships and difficulties with patient treatment/management. After investigating the validity and reliability of the scales, the correlations between the MMSE, the ERT, and the two scales of the IBC were calculated. The results suggested that the MMSE did not correlate with either of the two behavior scales, while the ERT correlated significantly with both of the scales. The study results lead to the conclusion that deteriorating emotion recognition ability, rather than deterioration of general cognition, influences the indifferent and awkward interpersonal behaviors of DAT patients.     

Low target prevalence is a stubborn source of errors in visual search tasks

In visual search tasks, observers look for targets in displays containing distractors. Likelihood that targets will be missed varies with target prevalence, the frequency with which targets are presented across trials. Miss error rates are much higher at low target prevalence (1%-2%) than at high prevalence (50%). Unfortunately, low prevalence is characteristic of important search tasks such as airport security and medical screening where miss errors are dangerous. A series of experiments show this prevalence effect is very robust. In signal detection terms, the prevalence effect can be explained as a criterion shift and not a change in sensitivity. Several efforts to induce observers to adopt a better criterion fail. However, a regime of brief retraining periods with high prevalence and full feedback allows observers to hold a good criterion during periods of low prevalence with no feedback.     

Functional magnetic resonance imaging responses relate to differences in real-world social experience

Although neuroimaging techniques have proven powerful in assessing neural responses, little is known about whether scanner-based neural activity relates to real-world psychological experience. A joint functional magnetic resonance imaging (fMRI)/experience-sampling study investigated whether individual differences in neurocognitive reactivity to scanner-based social rejection related to: (a) moment-to-moment feelings of social rejection during real-world social interactions ("momentary social distress") and (b) the extent to which these momentary feelings corresponded with end-of-day global assessments of social disconnection ("end-of-day social disconnection"). Individuals who showed greater activity in regions associated with affective and pain processing (dorsal anterior cingulate cortex, amygdala, periaqueductal gray) during scanner-based social rejection reported feeling greater momentary social distress during their daily social interactions. In contrast, individuals who showed greater activity in regions associated with memory and self-referential memory encoding (hippocampus, medial prefrontal cortex) showed a stronger correspondence between momentary social distress and end-of-day social disconnection, such that greater momentary social distress was associated with greater end-of-day social disconnection. These findings complement previous work showing a dissociation between momentary and retrospective reports of affect and suggest that these processes rely on dissociable neural systems.
