How psychological stress in the workplace influences presenteeism propensity: A test of the Demand–Control–Support model

The aim of this study is to examine the influence of the sources of psychological stress at work assumed by the Demand–Control–Support (DCS) model on presenteeism propensity. Research propositions are derived from the dynamic version of the Demand–Control model, to which we added the dimension of social support, which is part of the DCS model. Data were obtained from a large representative sample consisting of 1609 public and private sector workers living in the Canadian province of Québec, who responded to a questionnaire, administered using computer-assisted interviewing over a 3-month period in 2007–2008. The results indicate that the combination of low decision authority and high supervisor's support attenuates the positive relationship between job demands and presenteeism propensity within a 10-year time frame of exposure to a new job.     

The fundamental need to belong: on the distinction between growth and deficit-reduction orientations

The need for belongingness (the universal need to form and maintain positive, stable interpersonal relationships) has led to much research over the past decade. Although such a need is universal, some qualitative differences exist in its orientation. Specifically, two belongingness need orientations are proposed: a growth orientation (a belongingness need directed toward interpersonal actualization) and a deficit-reduction orientation (a belongingness need directed toward interpersonal deficit reduction or repair). It is hypothesized that a deficit-reduction orientation to the need to belong is associated with lower levels of intrapersonal and interpersonal psychological functioning compared to a growth orientation. The results of a series of four studies supported the proposed hypotheses. Implications of the proposed model for future research on the need to belong are discussed.     

The moderating effect of passion on the relation between activity engagement and positive affect

The present diary study investigates the moderating effect of passion on the relation between activity engagement and daily positive affect. In line with past research (Vallerand et al. 2003, Journal of Personality and Social Psychology, 85, 756) it is suggested that people with an obsessive passion have more difficulties putting their passion aside to invest themselves in other activities, to a point where they fail to experience positive affect during these activities. A sample of 154 college students reported their daily activity engagement and positive affect over a 2-week period. HLM analyses show that the more people have an obsessive passion the more they experience accentuated decreases in positive affect during days when they do not engage in their passion compared to days when they do. In contrast, harmonious passion predicts daily positive affect on days when people engage in their activity. These results are discussed in light of previous research on passion and positive affect.

Post-training intrahippocampal injection of synthetic poly-alpha-2,8-sialic acid-neural cell adhesion molecule mimetic peptide improves spatial long-term performance in mice

Several data have shown that the neural cell adhesion molecule (NCAM) is necessary for long-term memory formation and might play a role in the structural reorganization of synapses. The NCAM, encoded by a single gene, is represented by several isoforms that differ with regard to their content of alpha-2,8-linked sialic acid residues (PSA) on their extracellular domain. The carbohydrate PSA is known to promote plasticity, and PSA-NCAM isoforms remain expressed in the CA3 region of the adult hippocampus. In the present study, we investigated the effect on spatial memory consolidation of a PSA gain of function by injecting a PSA mimetic peptide (termed pr2) into the dorsal hippocampus. Mice were subjected to massed training in the spatial version of the water maze. Five hours after the last training session, experimental mice received an injection of pr2, whereas control mice received PBS or reverse peptide injections in the hippocampal CA3 region. Memory retention was tested at different time intervals: 24 h, 1 wk, and 4 wk. The results showed that the post-training infusion of pr2 peptide significantly increases spatial performance whenever it was assessed after the training phase. By contrast, administration of the control reverse peptide did not affect retention performance. These findings provide evidence that (1) PSA-NCAM is involved in memory consolidation processes in the CA3 hippocampal region, and (2) PSA mimetic peptides can facilitate the formation of long-term spatial memory when injected during the memory consolidation phase.     

Not all triads are created equal: further support for the importance of visual and semantic proximity in object identification

Identification deficits were investigated in ELM, a temporal lobe stroke patient with category-specific deficits. We replicated previous work done on FS, a patient with category specific deficits as a result of herpes viral encephalitis. ELM was tested using novel, computer generated shapes that were paired with artifact labels. We paired semantically close or disparate labels to shapes and ELM attempted to learn these pairings. Overall, ELM's shape-label confusions were most detrimentally affected when we used labels that referred to objects that were visually and semantically close. However, as with FS, ELM had as many errors when shapes were paired with the labels "donut," "tire," and "washer" as he did when they were paired with visually and semantically close artifact labels. Two explanations are put forth to account for the anomalous performance by both patients on the triad of donut-tire-washer.     

Gender and Changes in Trauma Narrative Following CBT for PTSD

Our study explored whether the characteristics of pretreatment trauma narratives could be used as indicators of posttraumatic stress disorder (PTSD) symptom severity before treatment. We also studied whether pretreatment characteristics could predict treatment efficacy. Although several studies suggest that fragmentation, proportion of internal events, and length in trauma narratives are associated with PTSD symptomatology, there are contradictions in the findings. Given the differences in trauma response between men and women, we considered the potential influence of gender. Before beginning a cognitive-behavioral therapy treatment, 66 participants verbally recounted their traumatic event during a diagnostic interview. After treatment, 48 participants once again provided a trauma narrative. PTSD symptom severity was assessed using the Clinician-Administered PTSD Scale. Linear regression analyses revealed that none of the pretreatment characteristics predicted treatment efficacy. Furthermore, the length of the trauma narrative was the only pretreatment characteristic that correlated with pretreatment PTSD symptomatology. This suggests that more severe symptomatology is associated with shorter narratives. We only found a significant gender difference in narrative length, which was longer in women than in men. Our findings not only highlight the need for additional research on the link between trauma narratives and PTSD symptomatology, but also stress the necessity of considering gender in this field of research. This could allow for enhanced treatments to target gender-specific needs, thus leading to more individualized care for PTSD patients.     

More on the Gendered Division of Household Labor: A Response to Commentators

This article is a response to the commentaries made regarding our original article (Lachance-Grzela and Bouchard 2010), which reviewed the state of research on the division of household labor and summarized the main theoretical perspectives used to explain why women continue to complete the larger share of household tasks. In the following pages, we underline how the commentators were helpful in identifying some limitations of the current research on the allocation of household labor and in suggesting relevant paths for future studies. We discuss points on which the commentators agree, such as the need to achieve a better understanding of all forms of inequalities, and points on which they disagree, such as the way researchers should proceed when studying the impact of national context. We also reply to each individual commentary. In response to Coltrane (2010), we discuss the causal loops that exist between gender inequalities in the private and public spheres. We agree with Davis (2010) who proposed that studying the question from other angles could help understand why household labor continues to be divided along gendered lines. We add to Claffey and Manning’s discussion (2010) of the paradox which stems from the fact that couples often perceive an objectively unequal division of household labor as fair to both partners. In conclusion, we take the opportunity to address additional issues related to the division of household labor. For instance, from a clinical psychology standpoint, we discuss how couples who strive to achieve a more egalitarian division of household labor do so.
