‘Be careful,or you'll act corruptly and make a carved image for yourselves,in the form of a figure,the likeness male or female’ (Deut. 4:16): A commentary on Norenzayan's Big Gods: How Religion Transformed Cooperation and Conflict (2013)

Norenzayan's book is an ambitious attempt to integrate recent research from behavioral economics and social psychology, particularly priming studies, into a book about religion. If the account is meant as an explanation of religion or big religion, it does not succeed. If it has more modest aims, namely to describe how surveillance institutions, of which big religion is one important class, can sometimes lead to cooperation and conflict, then it is quite successful in doing so.     

Evidence for Implicit Learning in Syntactic Comprehension

This study provides evidence for implicit learning in syntactic comprehension. By reanalyzing data from a syntactic priming experiment (Thothathiri & Snedeker, 2008), we find that the error signal associated with a syntactic prime influences comprehenders' subsequent syntactic expectations. This follows directly from error‐based implicit learning accounts of syntactic priming, but it is unexpected under accounts that consider syntactic priming a consequence of temporary increases in base‐level activation. More generally, the results raise questions about the principles underlying the maintenance of implicit statistical knowledge relevant to language processing, and about possible functional motivations for syntactic priming.     

Dynamic Simulation and Static Matching for Action Prediction: Evidence From Body Part Priming

Accurately predicting other people's actions may involve two processes: internal real‐time simulation (dynamic updating) and matching recently perceived action images (static matching). Using a priming of body parts, this study aimed to differentiate the two processes. Specifically, participants played a motion‐controlled video game with either their arms or legs. They then observed arm movements of a point‐light actor, which were briefly occluded from view, followed by a static test pose. Participants judged whether this test pose depicted a coherent continuation of the previously seen action (i.e., “action prediction task”). Evidence of dynamic updating was obtained after compatible effector priming (i.e., arms), whereas incompatible effector priming (i.e., legs) indicated static matching. Together, the results support action prediction as engaging two distinct processes, dynamic simulation and static matching, and indicate that their relative contributions depend on contextual factors like compatibility of body parts involved in performed and observed action.     

The effects of a positive health priming intervention on somatic complaints

Somatic complaints are common and form a major burden. Previous studies suggested that such complaints might be increased by ‘illness-related memory’, for example due to worries about health. In this ambulatory study we tested whether we could decrease somatic complaints through enhancing the activation of health-related memory by a ‘positive health’-priming intervention. Forty-three students were randomly assigned to the ‘positive health’-group or a control group. Using online measures, participants reported negative affect (NA) and somatic complaints for a period of six days, while each morning performing the priming task. The intervention caused a decrease in somatic complaints but only for participants with low trait NA or low somatosensory amplification. These findings seem to suggest that priming or other interventions directed at activating positive health memory might reduce health complaints, but only in certain subgroups.     

Unconscious Responses to Threatening Pictures: Interactive Effect of Trait Anxiety and Social Desirability on Skin Conductance Responses

The purpose of the present study was to examine the role of trait anxiety and social desirability on skin conductance responses (SCRs) following exposure to masked and unmasked pictures in a non‐clinical sample. The most prominent results were found with regard to masked pictures (i.e. subliminal). Higher levels of social desirability were associated with a decrease in SCRs to masked threat pictures (relative to neutral), whereas elevated levels of trait anxiety were associated with an increase in SCRs. This latter effect, however, was mainly seen among participants who simultaneously scored low on social desirability. These results were discussed in terms of trait anxiety (combined with lower social desirability scores) being associated with (i) enhanced autonomic responses to threatening information most evident at a pre‐attentive level, that (ii) may potentially be a vulnerability marker for anxiety disturbances.     

Altered working memory capacity for social threat words in high versus low social anxiety

ABSTRACT

Background and objectives: Differences in working memory capacity (WMC) have been suggested in individuals with high levels of social anxiety (SA). Specifically, these individuals may preferentially maintain socially threatening material in working memory.

Design and methods: We adapted the digit span task to a series of word span tasks. We assessed WMC for lists of words that varied in terms of their threat-relatedness, in individuals either high or low in SA.

Results: Experiment 1 revealed reduced WMC for socially threatening words in those with high compared to low SA. Importantly, this relative reduction in WMC was driven by the low SA group showing expanded capacity for socially threatening words relative to neutral or generally threatening words. Furthermore, reductions in WMC for social threat were uniquely predicted by SA, and not by other theoretically related constructs such as state general anxiety, trait general anxiety, or depression. Experiment 2 showed that the semantic similarity of the words within each list was not responsible for the differences in WMC between list type or SA group.

Conclusions: Our findings suggest that individuals high in SA may fail to upregulate WMC for social information due to the activation of, or rumination upon, socially threatening concepts.     

Book Review

Repetition priming is one of the most robust phenomena in cognitive psychology, but participants vary substantially on the amount of priming that they produce. The current experiments assessed the reliability of repetition priming within individuals. The results suggest that observed differences in the size of the repetition priming effect across participants are largely reliable and result primarily from systematic processes. We conclude that the unreliability of semantic priming observed by Stolz, Besner, and Carr (2005) is specific to uncoordinated processes in semantic memory, and that this unreliability does not generalize to other processes in visual word recognition. We consider the implications of these results for theories of automatic and controlled processes that contribute to priming. Finally, we emphasize the importance of reliability for researchers who use similar paradigms to study individual and group differences in cognition.     

The influence of visual short-term memory on size perception

We show that perceived size of visual stimuli can be altered by matches between the contents of visual short-term memory and stimuli in the scene. Observers were presented with a colour cue (to hold in working memory or to merely identify) and subsequently had to indicate which of the two different-coloured objects presented simultaneously on the screen appeared bigger (or smaller). One of the two objects for size judgements had the same colour as the cue (matching stimulus) and the other did not (mismatching stimulus). Perceived object size was decreased by the reappearance of the recently seen cue, as there were more size judgement errors on trials where the matching stimulus was physically bigger (relative to the mismatching stimulus) than on trials where the matching stimulus was physically smaller. The effect occurred regardless of whether the visual cue was actively maintained in working memory or was merely identified. The effect was unlikely generated by the allocation of attention, because shifting attention to a visual stimulus actually increased its perceived size. The findings suggest that visual short-term memory, whether explicit or implicit, can decrease the perceived size of subsequent visual stimuli.     

A psycho-social system approach to well-being: Empirically deriving the Five Domains of Positive Functioning

A new psycho-social system approach to well-being is presented, in which psychological and social functioning is understood through an empirically derived framework of five domains. A quantitative co-term analysis was performed on 3466 terms within 18,401 PsycINFO^® journal documents on topics related to positive psychology (PP) across disciplines such as psychology, education, management, business and psychiatry. The analysis revealed that research on PP topics can be classified into five broad domains: attention and awareness, comprehension and coping, emotions, goals and habits, and virtues and relationships. These domains provide a new systematic framework, the Five Domains of Positive Functioning, for understanding positive psycho-social functioning and exploring the underlying ways in which people function to achieve well-being outcomes. When used within the psycho-social system approach, the framework can be used in future research to clarify mechanisms of change, facilitate comparisons between different PP interventions and suggest ways to improve intervention effectiveness.     

Visual experience is not necessary for efficient survey spatial cognition: Evidence from blindness

This study investigated whether the lack of visual experience affects the ability to create spatial inferential representations of the survey type. We compared the performance of persons with congenital blindness and that of blindfolded sighted persons on four survey representation-based tasks (Experiment 1). Results showed that persons with blindness performed better than blindfolded sighted controls. We repeated the same tests introducing a third group of persons with late blindness (Experiment 2). This last group performed better than blindfolded sighted participants, whereas differences between participants with late and congenital blindness were nonsignificant. The present findings are compatible with results of other studies, which found that when visual perception is lacking, skill in gathering environmental spatial information provided by nonvisual modalities may contribute to a proper spatial encoding. It is concluded that, although it cannot be asserted that total lack of visual experience incurs no cost, our findings are further evidence that visual experience is not a necessary condition for the development of spatial inferential complex representations.
