Gender differences in patterns of emotional distress following heart transplantation

The study provides the first empirical evaluation of gender differences in psychological symptomatology and DSM-III-R major depressive disorder (MDD) across the first year following heart transplantation. An important goal was to identify physical health-related and psychosocial factors that could account for, or mediate, any association between gender and psychological distress. The sample for the present analyses was drawn from a larger cohort of 172 heart recipients and included all 28 women in the cohort plus 118 men who were matched demographically with the group of women. Detailed patient assessments were completed at 2, 7, and 12 months posttransplant. As expected, women's symptom levels were consistently higher than men's. However, while men's symptom levels in all areas declined with time posttransplant, women's distress in the area of depression initially improved but then worsened by the 12-month assessment. The distribution of episodes of MDD showed a temporal pattern of gender differences similar to that of depressive symptoms. The most important mediators of the gender-depression relationship were factors related to early posttransplant daily functional limitations: women reported more impairments in daily activities. Higher levels of such impairments, in turn, predicted subsequently higher depression levels by 12 months posttransplant. Several additional variables pertaining to transplant-related concerns and a low sense of personal mastery—while not serving as mediators—exerted their own independent effects on 12-month depression levels. The findings are relevant to the tailoring of educational and clinical interventions to the individual needs of women and men who receive heart transplants.Roberta G.

Ritualistic,Theistic, and Existential Spirituality: Initial Psychometric Qualities of the RiTE Measure of Spirituality

An expanded model to conceptualize sacred human experiences is discussed wherein the term Spirituality is broadened to include: (1) Ritualistic Spirituality, (2) Theistic Spirituality, and (3) Existential Spirituality. However, a measure incorporating this expanded model does not yet exist. A 67-item self-report questionnaire was developed and data were collected from 1,301 undergraduate students. A series of factor analytic procedures yielded a three-factor structure consistent with the guiding theoretical model and refinement produced three 10-item subscales. Evidence for construct validity and sound psychometric properties was indicative of a reliable, valid, and unique tool to assess the multidimensional nature of spirituality.     

Preferential processing of threatening facial expressions using the repetition blindness paradigm

Background: Neuroanatomical evidence suggests that the human brain has dedicated pathways to rapidly process threatening stimuli. This processing bias for threat was examined using the repetition blindness (RB) paradigm. RB (i.e., failure to report the second instance of an identical stimulus rapidly following the first) has been established for words, objects and faces but not, to date, facial expressions. Methods: 78 (Study 1) and 62 (Study 2) participants identified repeated and different, threatening and non-threatening emotional facial expressions in rapid serial visual presentation (RSVP) streams. Results: In Study 1, repeated facial expressions produced more RB than different expressions. RB was attenuated for threatening expressions. In Study 2, attenuation of RB for threatening expressions was replicated. Additionally, semantically related but non-identical threatening expressions reduced RB relative to non-threatening stimuli. Conclusions: These findings suggest that the threat bias is apparent in the temporal processing of facial expressions, and expands the RB paradigm by demonstrating that identical facial expressions are susceptible to the effect.     

The Influence of Social Status on Token Women Leaders' Expectations About Leading Male-Dominated Groups

Prior research has shown that women report mostly negative expectations about being a gender-token in male-dominated work groups. We speculate that this is partially caused by the socially ascribed status devaluation of women. In this study we investigated the degree to which elevated social status may lessen negative expectations of gender-token women assigned to leadership positions. Sixty-three undergraduate women participated in 1 of 3 tokenism conditions: (1) nontoken, (2) gender-token, and (3) high-status gender-token. In all conditions participants were led to believe that they would be leading a group of men in a decision-making exercise. Leader expectations were then assessed. The results suggest that increased social status may help prevent gender-token women from developing negative expectations about interactions with male-dominated work groups.     

Optimism and Hope After Multiple Disasters: Relationships to Health-Related Quality of Life

Natural and technological disasters are devastating events for individuals and communities. The authors examined the role of optimism and hope in predicting health indicators in a sample of disaster survivors who were exposed to Hurricanes Katrina and Rita in 2005. Participants were noncoastal residents, current coastal residents, and current coastal fishers who were also economically impacted by the 2010 BP Deepwater Horizon oil spill. All participants completed measures of optimism, hope, and the SF-36 Health Survey, which provides summary scores for mental and physical health. Logistic regressions indicated that optimism and hope were independently and positively associated with better mental health (OR = 1.21; 95% CI: 1.10, 1.32 and OR = 1.11; 95% CI: 1.05, 1.17 respectively). Neither optimism nor hope were significantly associated with physical health when considered alone. However, optimism interacted with prior lifetime trauma, where optimism only significantly predicted physical health for those with higher previous trauma scores. These results provide new evidence of optimism and hope as protective factors that may positively impact mental health after multiple disasters.     

Hippocampal theta-dependent eyeblink classical conditioning: coordination of a distributed learning system

Richard F. Thompson's study of the neurobiological substrates of learning and memory has been a career-long endeavor, chosen early and pursued with uncompromising depth and breadth. His systematic mapping of the major brain systems and mechanisms involved in eyeblink classical conditioning (EBCC) established the essential role of the cerebellum. Investigations of the interactions between the hippocampus and cerebellum are critically important to this literature, given the essential involvement of these structures in trace EBCC as well as an important modulatory role of the hippocampus in delay EBCC. Hippocampal theta (3-7Hz) oscillations are known to reflect a functional state that influences both the timing of unit firing and the potential for neural plasticity in the hippocampus and other structures. Herein we present a brief summary of research demonstrating the behavioral enhancement due to theta and the underlying neurobiological correlates in both hippocampus and cerebellum during EBCC. Hippocampal and cerebellar local field potentials (LFPs) show that these distantly interconnected brain structures become precisely synchronized when conditions favor rapid behavioral acquisition. Our results suggest a major role for theta in coordinating the widely distributed memory system for trace EBCC. These and other important findings reflect Thompson's own work and his early-career mentoring of scientists whose contributions to the EBCC literature have ensured his major and lasting impact on the neurobiology of learning and memory.     

Being well at work: the impact of organizational climate and social identity on employee stress and self-esteem over time

In organizational psychology, staff perceptions of organizational climate have been found to be an important predictor of employee outcomes, such as employee stress. However, only a small pool of research has investigated the psychological mechanism that underpins the relationship, and no past literature has explored how the relationship persists over time. This paper uses the social identity approach to investigate whether social identification predicts and mediates the relationship between staff perceptions of organizational climate and their levels of stress and self-esteem over time. Employing a sample of public school teachers, the study was conducted over two years (N = 281, 65 schools). The results indicated that social identification fully mediated the relationship between organizational climate and self-esteem longitudinally but showed no significant relationship with stress. The implications of these findings are discussed, with recommendations for future research.
