Food caching by western scrub-jays (Aphelocoma californica) is sensitive to the conditions at recovery

Western scrub-jays (Aphelocoma californica) cached perishable and nonperishable food items, which they could recover after both short and long retention intervals. When perishable items were always degraded at recovery, jays decreased the number of perishable items cached and increased their caching of nonperishable items, relative to a control group whose caches were always fresh at recovery. Jays reduced the number of nonperishable items cached, however, when highly preferred food items were degraded only after the long retention intervals. The findings are discussed in terms of the role of retrospective and prospective processes in the control of caching.     

Modelling relative motion to facilitate intra-limb coordination

The importance of relative motion information when modelling a novel motor skill was examined. Participants were assigned to one of four groups. Groups 1 and 2 viewed demonstrations of a skilled cricket bowler presented in either 'video' or 'point light' format. Group 3 observed a single point of light pertaining to the 'wrist' of the skilled bowler only. Participants in Group 4 did not receive a demonstration and acted as controls. During 60 acquisition trials, participants in the demonstration groups viewed a model five times before each 10-trial block. Retention was examined the following day. Intra-limb coordination was assessed for the right elbow relative to the wrist in comparison to the model. The demonstration groups showed greater concordance with the model than the control group. However, the 'wrist' group performed less like the model than the 'point light' and 'video' groups, who did not differ from each other. These effects were maintained in retention. Relative motion information aided the acquisition of intra-limb coordination, while making this information more salient (through point lights) provided no additional benefit. The motion of the model's bowling arm was replicated more closely than the non-bowling arm, suggesting that information from the end-effector is prioritized during observation for later reproduction.     

Body image dissatisfaction: gender differences in eating attitudes,self-esteem,and reasons for exercise

Two hundred and thirty-five adolescents completed a questionnaire on the subject of eating attitudes, self-esteem, reasons for exercise, and their ideal versus current body size and shape. As predicted, boys were as likely to want to be heavier as lighter, whereas very few girls desired to be heavier. Only girls associated body dissatisfaction with the concept of self-esteem. Male self-esteem was not affected by body dissatisfaction. Specific reasons for exercise were found to correlate with low self-esteem and disordered eating, regardless of sex. The results are discussed in relation to burgeoning published research in this area.     

Toward a unified account of spacing effects in explicit cued-memory tasks

Memory for repeated items improves when presentations are spaced during study. This effect is found in memory tasks using different types of material, paradigms, and participant populations. Although several explanations have been proposed, none explains the presence of spacing effects in cued-memory tasks for unfamiliar stimuli. Two experiments assessed the spacing effect on a yes-no recognition-memory task using nonwords and words as targets. The main results showed that changing the font between repeated occurrences of targets at study removed the spacing effect for nonwords only. A 3rd experiment using lexical decision showed that the font manipulation reduced repetition priming of nonwords when items were repeated at Lag 0. These results suggest that short-term perceptual priming supports spacing effects in cued-memory tasks for unfamiliar stimuli.     

Where “culture wars” and therapy meet: Exploring the intersection between political issues and therapeutic practice

In the era of “culture wars,” instances where client and practitioner discuss political issues in therapy may become more frequent. This paper introduces the way in which “culture wars” manifest in today's societies and highlights the importance of therapeutic practitioners to engage with and explore their own views in relation to these polarising political debates. In doing so, this paper reflects upon the existing research focussing on the way in which “culture wars” enter the therapeutic encounter and highlights the feelings of anxiety and conflict that arise when practitioners are tasked with “talking politics” with clients. It considers the implications for practice and policy and concludes with recommendations for future scholarship, arguing for more culturally specific studies that examine how “culture wars” issues impact therapeutic work in a variety of international settings.     

Prosocial rule breaking,ingroups and social norms: Parental decision-making about COVID-19 rule breaking in the UK

The British public generally adhered to COVID-19-related restrictions, but as the pandemic drew on, it became challenging for some populations. Parents with young children were identified as a vulnerable group. We collected rich, mixed-methods survey data from 99 UK-based parents (91 mothers) of children under 12, who described their lockdown transgressions. Household mixing was the most prevalent broken rule. Template analysis found that rule breaking was driven by ‘ingroup-level’ prosocial motivations to protect the mental and social health of family and loved ones, and that parents were ‘engaged’ decision-makers who underwent careful deliberation when deciding to break rules, making trade-offs, bending rules, mitigating risks, reaching consensus, and reacting to perceived rule injustices. Cumulative link models found that the perceived reasonableness of rule violations was predicted by social norms. Rules were broken by parents not for antisocial reasons, but for ‘ingroup-level’ prosocial reasons, linked to supporting loved ones.     

Running with emotion: When affective content hampers working memory performance

This study tested the hypothesis that affective content may undermine rather than facilitate working memory (WM) performance. To this end, participants performed a running WM task with positive, negative and neutral words. In typical running memory tasks, participants are presented with lists of unpredictable length and are asked to recall the last three or four items. We found that accuracy with affective words decreased as lists lengthened, whereas list length did not influence recall of neutral words. We interpreted this pattern of results in terms of a limited resource model of WM in which valence represents additional information that needs to be manipulated, especially in the context of difficult trials.
