When the ends outweigh the means: Mood and level of identification in depression

Research in healthy controls has found that mood influences cognitive processing via level of action identification: happy moods are associated with global and abstract processing; sad moods are associated with local and concrete processing. However, this pattern seems inconsistent with the high level of abstract processing observed in depressed patients, leading Watkins (2008, 2010) to hypothesise that the association between mood and level of goal/action identification is impaired in depression. We tested this hypothesis by measuring level of identification on the Behavioural Identification Form after happy and sad mood inductions in never-depressed controls and currently depressed patients. Participants used increasingly concrete action identifications as they became sadder and less happy, but this effect was moderated by depression status. Consistent with Watkins' (2008) hypothesis, increases in sad mood and decreases in happiness were associated with shifts towards the use of more concrete action identifications in never-depressed individuals, but not in depressed patients. These findings suggest that the putatively adaptive association between mood and level of identification is impaired in major depression.     

Ageing stereotypes influence the transmission of false memories in the social contagion paradigm

ABSTRACT

These experiments are the first to investigate the impact of confederate accuracy, age, and age stereotypes in the social contagion of memory paradigm. Across two experiments, younger participants recalled household scenes with an actual (Experiment 1) or virtual (Experiment 2), older or younger confederate who suggested different proportions (0%, 33% or 100%) of false items during collaboration. In Experiment 2, positive and negative age stereotypes were primed by providing bogus background information about our older confederate before collaboration. Across both experiments, if confederates suggested false items participants readily incorporated these into their own memory reports. In Experiment 1, when no age stereotype was primed, participants adopted similar proportions of false items from younger and older confederates. Importantly, in Experiment 2, when our older confederate was presented in terms of negative ageing stereotypes, participants reported less false items and were better able to correctly identify the source of those false items.     

SHS-Related Pediatric Sick Visits are Linked to Maternal Depressive Symptoms Among Low-Income African American Smokers: Opportunity for Intervention in Pediatrics

Maternal smoking and depressive symptoms are independently linked to poor child health outcomes. However, little is known about factors that may predict maternal depressive symptoms among low-income, African American maternal smokers—an understudied population with children known to have increased morbidity and mortality risks. The objective of this study was to test the hypothesis that secondhand smoke exposure (SHSe)-related pediatric sick visits are associated with significant maternal depressive symptoms among low-income, African American maternal smokers in the context of other depression-related factors. Prior to randomization in a behavioral counseling trial to reduce child SHSe, 307 maternal smokers in Philadelphia completed the Center for Epidemiologic Studies Depression (CES-D) and questionnaires measuring stressful events, nicotine dependence, social support, child health and demographics. CES-D was dichotomized at the clinical cutoff to differentiate mothers with significant versus low depressive symptoms. Results from direct entry logistic regression demonstrated that maternal smokers reporting more than one SHSe-related sick visit (OR 1.38, p < .001), greater perceived life stress (OR 1.05, p < .001) and less social support (OR 0.82, p < .001) within the last 3 months were more likely to report significant depressive symptoms than mothers with fewer clinic visits, less stress, and greater social support. These results suggest opportunities for future hypothesis-driven evaluation, and exploration of intervention strategies in pediatric primary care. Maternal depression, smoking and child illness may present as a reciprocally-determined phenomenon that points to the potential utility of treating one chronic maternal condition to facilitate change in the other chronic condition, regardless of which primary presenting problem is addressed. Future longitudinal research could attempt to confirm this hypothesis.     

The Impact of Race on Metabolic Disease Risk Factors in Women With and Without Posttraumatic Stress Disorder

The literature on PTSD and metabolic disease risk factors has been limited by lacking investigation of the potential influence of commonly comorbid disorders and the role of race. In this study data were provided by a sample of 134 women (63 PTSD and 71 without PTSD). Separate sets of models examining associations of psychiatric disorder classifications with metabolic disease risk factors were used. Each model included race (African American or Caucasian), psychiatric disorder, and their interaction. There was an interaction of race and PTSD on body mass index, abdominal obesity, and triglycerides. While PTSD was not generally associated with deleterious health effects in African American participants, PTSD was related to worse metabolic disease risk factors in Caucasians. MDD was associated with metabolic disease risk factors, but there were no interactions with race. Results support the importance of race in the relationship between PTSD and metabolic disease risk factors. Future research would benefit from analysis of cultural factors to explain how race might influence metabolic disease risk factors in PTSD.     

A Personal Construct Approach to Understanding Stress in Mothers of Children Diagnosed with Autism Spectrum Disorders

This study explored the contribution of personal construct psychology (PCP) and the repertory grid technique to understanding stress when raising a child diagnosed with autism spectrum disorder (ASD). Associations between child level of functional impairment, parenting stress, psychological distress, and maternal construing were examined in mothers of 25 children diagnosed with ASD. Results suggest that a personal construct perspective may help delineate factors involved in parent adjustment to ASD.     

Stimulus-specific dynamics of learning in conjunction search tasks

We investigated the time course of learning in visual search for within-dimension conjunctions in homogeneous (inverted V in Vs) or heterogeneous distractors (L in 90° counterclockwise-rotated Ls and 180° rotated Ls), and for across-dimension conjunctions search (green\in green/s and red\s). Two learning sessions of 10 and 5 blocks each took place three months apart. In the first session, the reduction in mean search time was greater for within-dimension conjunctions with heterogeneous distractors. Learning endured from one session to the other for all stimuli, suggesting that learning can be long-term in search for feature conjunctions. However, when the positional regularity between elements was perturbed, the effect of prior learning was reduced for homogeneous within-dimension conjunctions. This suggests that, for these stimuli, learning facilitates grouping by positional regularity. Finally, the learning effect with homogeneous withindimension conjunctions disappeared when both target and distractors were rotated to modify the orientation of conjunction patterns. This suggests that learning improves a grouping mechanism selective for the relative orientations of combined form features.     

Similarity modulates the face-capturing effect in change detection

We investigated whether similarity among faces could modulate the face-capturing effect in change detection. In Experiment 1, a singleton search task was used to demonstrate that a face stimulus captures attention and the odd-one-out hypothesis cannot account for the results. Searching for a face target was faster than searching for a nonface target no matter whether distractor–distractor similarity was low or high. The fast search, however, did not lead to a face-detection advantage in Experiment 2 when the pre- and postchange faces were highly similar. When participants in Experiment 3 had to divide their attention between two faces in stimulus displays for change detection, detection performance was worse than performance in detecting nonface changes. The face-capturing effect alone is insufficient to produce the face-detection advantage. Face processing is efficient but its effect on performance depends on the stimulus–task context.     

“Toxin handling” and well-being: The case of the human resources manager

This study uses the job demands–resources model and multiple role theory to gain an understanding of the “toxin handling–well-being” relationship. “Toxin handlers” are empathetic managers willing to try to address pain and suffering in organizations (Frost, 2007). We use data from semistructured, in-depth interviews with HR managers to investigate the impact of the toxin handling role on well-being. The interviews indicate that toxin handling does not necessarily lead to the toxin handler’s ill health, because factors such as organizational and personal resources can influence that relationship. Further, toxin handlers can face very different toxin handling demands. These differences in the toxin handler’s resources and demands can lead to the full spectrum of possible health consequences of toxin handling (from decreased to enhanced health) for different toxin handlers.     

Development and implementation of a spiritual coping group intervention for adults living with HIV/AIDS: A pilot study

The aims of the current study were to (1) describe a spirituality-oriented, group pilot intervention for HIV-positive adults, and (2) examine the preliminary impact of the intervention among a sample (N?=?13) of adults living with HIV in an urban city in northeast United States. The 8-session intervention, based on the cognitive theory of stress and coping and the framework of spiritual coping, addressed stressors unique to HIV disease. Changes in spiritual coping and mental health were evaluated using a within group pretest-posttest design. Results revealed that, at post-intervention, participants reported higher self-rated religiosity, more use of positive spiritual coping, lower use of negative spiritual coping, and lower depression. Studies using a randomized, controlled design with larger samples of individuals with HIV are needed to determine the efficacy of a spiritual intervention when compared to a secular one.
