Views of a good life and allostatic load: Physiological correlates of theories of a good life depend on the socioeconomic context

This research examines the relationship between one’s theory of a good life and allostatic load, a marker of cumulative biological risk, and how this relationship differs by socioeconomic status. Among adults with a bachelor’s degree or higher, those who saw individual characteristics (e.g. personal happiness, effort) as part of a good life had lower levels of allostatic load than those who did not. In contrast, among adults with less than a bachelor’s degree, those who saw supportive relationships as part of a good life had lower levels of allostatic load than those who did not. These findings extend past research on socioeconomic differences in the emphasis on individual or relational factors and suggest that one’s theory of a good life has health implications.     

Knowing that strawberries are red and seeing red strawberries: the interaction between surface colour and colour knowledge information

This study investigates the interaction between surface and colour knowledge information during object recognition. In two different experiments, participants were instructed to decide whether two presented stimuli belonged to the same object identity. On the non-matching trials, we manipulated the shape and colour knowledge information activated by the two stimuli by creating four different stimulus pairs: (1) similar in shape and colour (e.g. TOMATO–APPLE); (2) similar in shape and dissimilar in colour (e.g. TOMATO–COCONUT); (3) dissimilar in shape and similar in colour (e.g. TOMATO–CHILI PEPPER) and (4) dissimilar in both shape and colour (e.g. TOMATO–PEANUT). The object pictures were presented in typical and atypical colours and also in black-and-white. The interaction between surface and colour knowledge showed to be contingent upon shape information: while colour knowledge is more important for recognising structurally similar shaped objects, surface colour is more prominent for recognising structurally dissimilar shaped objects.     

Evaluating a humane alternative to the bark collar: Automated differential reinforcement of not barking in a home‐alone setting

The aim of this study was to develop a humane alternative to the traditional remote devices that deliver punishers contingent on home‐alone dog barking. Specifically, we evaluated the use of remote delivery of food contingent on intervals of not barking during the pet owner's absence. In Experiment 1, 5 dogs with a history of home‐alone nuisance barking were recruited. Using an ABAB reversal design, we demonstrated that contingent remote delivery of food decreased home‐alone barking for 3 of the dogs. In Experiment 2, we demonstrated that it is possible to thin the differential‐reinforcement‐of‐other‐behavior (DRO) schedule gradually, resulting in a potentially more acceptable treatment. Our results benefit the dog training community by providing a humane tool to combat nuisance barking.     

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.     

Challenge and threat emotions as antecedents of recovery experiences: findings from a diary study with blue-collar workers

The aim of this study was (1) to investigate whether threat (e.g., anxiety, fear) and challenge (e.g., confidence, excitement) emotions that employees experience before work while thinking about the upcoming workday predict their recovery experiences (i.e., psychological detachment, relaxation, mastery, and control) after work and (2) to explore the moderating role of job control on the effect of threat and challenge emotions on recovery experiences. For two to four weeks, 57 blue-collar workers at an airport’s hub station completed a diary. Multilevel analyses (N = 1104) reveal that threat emotions in the morning decrease psychological detachment and relaxation after work. Job control buffers this negative effect. Furthermore, challenge emotions in the morning boost mastery after work. Next, when employees have low job control, challenge emotions also boost the recovery experience control. Practical implications and the need for future studies to examine more fine-grained mechanisms for better understanding how threat and challenge emotions experienced before starting work affect recovery experiences after work are discussed.
