Psychoneuroimmunology

Psychoneuroimmunology (PNI) is concerned with the processes that mediate the relationships between psychological and social factors and disease or health. The focus of PNI is particularly the bidirectional relationships between these factors and the immune system, through nervous system and endocrine system pathways. This paper will provide an introduction to PNI. This will include a brief tour of the immune system and its measurement and the physiology of mind–body connections. Two pertinent questions will then arise: whether social and psychological factors can make healthy people sick and how these factors influence the course of diseases. These questions will be discussed using evidence from observational, experimental, and intervention studies.     

Power in relationships of women with depression

To identify marital power difficulties specifically associated with depression, twenty couples in which the female partner was depressed were compared on a range of interpersonal power variables with twenty healthy control couples and also with twenty couples in which the female partner had a disorder other than depression (specifically panic disorder with agoraphobia (PDA)). Couples in the depressed group had two features that distinguished them from couples in both the PDA and control groups and which were independent of relationship dissatisfaction. In the depressed group, both partners reported more physical assault in the year prior to the study and depressed women were more dissatisfied with their control of surplus spending money. Couples in the depressed group had a series of features that distinguished them from couples in both the PDA and control groups but which were due in part to relationship dissatisfaction. Depressed women were less committed to their relationships. Both partners in depressed couples reported more demand–withdraw transactions and less mutual constructive communication within their relationships. Depressed women reported more dissatisfaction with decision-making and greater dissatisfaction in childcare task distribution.     

Attitudes Toward Violence Against Women: A Cross-Nation Study

An understanding of attitudes toward violence against women is vital for effective prevention strategies. In this study we examined attitudes regarding violence against women in samples of undergraduate women and men students from four countries: India, Japan, Kuwait, and the United States. Attitudes toward sexual assault and spousal physical violence differed between men and women and across the four countries. Variations in gender differences across countries indicated that, for attitudes regarding sexual assault of women in particular, sociocultural factors may be a stronger influence than gender. Findings suggest the importance of examining differences within the larger sociocultural context of political, historical, religious, and economic influences on attitudes toward gender roles and violence against women.     

The effects of mindfulness-based interventions for health and social care undergraduate students – a systematic review of the literature

Health and social care undergraduate students experience stress due to high workloads and pressure to perform. Consequences include depression and burnout. Mindfulness may be a suitable way to reduce stress in health and social care degree courses. The objective of this systematic review is to identify and critically appraise the literature on the effects of Mindfulness-Based Interventions for health and social care undergraduate students. PubMed, EMBASE, Psych Info, CINAHL, The Cochrane Library and Academic Search Complete were searched from inception to 21st November 2016. Studies that delivered Mindfulness-Based Stress Reduction, Mindfulness-Based Cognitive Therapy, or an intervention modelled closely on these, to health or social care undergraduate students were included. Eleven studies, representing medicine, nursing and psychology students met the inclusion criteria. The most commonly used measurement tools were; the Five Facet Mindfulness Questionnaire and the General Health Questionnaire. Short term benefits relating to stress and mood were reported, despite all but one study condensing the curriculum. Gender and personality emerged as factors likely to affect intervention results. Further research with long-term follow-up is required to definitively conclude that mindfulness is an appropriate intervention to mentally prepare health and social care undergraduate students for their future careers.     

Great ape gestures: intentional communication with a rich set of innate signals

Great apes give gestures deliberately and voluntarily, in order to influence particular target audiences, whose direction of attention they take into account when choosing which type of gesture to use. These facts make the study of ape gesture directly relevant to understanding the evolutionary precursors of human language; here we present an assessment of ape gesture from that perspective, focusing on the work of the “St Andrews Group” of researchers. Intended meanings of ape gestures are relatively few and simple. As with human words, ape gestures often have several distinct meanings, which are effectively disambiguated by behavioural context. Compared to the signalling of most other animals, great ape gestural repertoires are large. Because of this, and the relatively small number of intended meanings they achieve, ape gestures are redundant, with extensive overlaps in meaning. The great majority of gestures are innate, in the sense that the species’ biological inheritance includes the potential to develop each gestural form and use it for a specific range of purposes. Moreover, the phylogenetic origin of many gestures is relatively old, since gestures are extensively shared between different genera in the great ape family. Acquisition of an adult repertoire is a process of first exploring the innate species potential for many gestures and then gradual restriction to a final (active) repertoire that is much smaller. No evidence of syntactic structure has yet been detected.     

Fairness Reduces the Negative Effects of Organizational Politics on Turnover Intentions,Citizenship Behavior and Job Performance

Responses from 150 employees revealed that procedural justice reduced the negative effects of perceptions of covert, self-serving political behaviors (e.g., going along with others), but not overt political behaviors (e.g., tearing others down to build up self) on turnover intentions. Both procedural and interactional justice moderated effects of covert, but not overt political behaviors, on OCB beneficial to the organization; however, the interaction between interactional justice and covert behaviors was in the opposite direction than hypothesized. Neither interactional nor procedural justice moderated the two forms of perceptions of politics on supervisory rated job performance or OCB beneficial to supervisors.

Reasoning counterfactually: making inferences about things that didn't happen

The authors investigated the relationship between reasoners' understanding of subjunctive conditionals (e.g., if p had happened, then q would have happened) and the inferences they were prepared to endorse. Reasoners who made a counterfactual interpretation of subjunctive statements (i.e., they judged the statement to imply that p and q did not happen) endorsed different inferences than those who did not. Those who made a counterfactual interpretation were more likely to (a) judge the situation in which p and q occurred to be inconsistent with the conditional statement and (b) make negative inferences such as modus tollens (i.e., approximately q therefore approximately p). These findings occurred with familiar and unfamiliar content, affirmative and negative conditionals, and conditional and biconditional relations.     

Comparison of gait patterns between young and elderly women: an examination of coordination

This study investigated intralimb coordination during walking in young and elderly women using the theoretical model of dynamical systems. 20 women, 10 Young (M age=24.6 yr., SD= 3.2 yr.) and 10 Elderly (M age=73.7 yr., SD=4.9 yr.), were videotaped during free speed gait and gait perturbed by an ankle weight. Two parameters, one describing the phasing relationship between segments (mean absolute relative phase) and the other the variability of this relationship (deviation in phase), were calculated from the kinematics. Two-way analysis of variance (age and weight) with repeated measures on weight indicated that during the braking period the weight increased the mean absolute relative phase between the shank and the thigh and decreased it between the foot and the shank. The Elderly women had significant smaller values for the mean absolute relative phase between the shank and the thigh during the braking period. For the same period, deviation in phase increased for the segmental 'relationship between the shank and the thigh. The findings suggest that changes in intralimb coordination take place with asymmetrical weighting and the aging process. These changes are most clearly present during the braking period.
