Semantic priming of familiar faces

A series of experiments to explore the effect of priming by semantically related items in familiarity judgement tasks using faces and names that are analogous to lexical decision tasks is reported. In the first experiment, the semantic priming effect in face recognition reported by Bruce (1983) was explored in more detail by including neutral as well as associated and unrelated primes and by varying the prime-target SOA from 250 to 1,000 msec. Significant facilitation effects, with no inhibition, were found at all three SOAs. To explore the analogy between the processing of faces and verbal materials, a second experiment used names rather than faces. The difference between related and unrelated conditions at 250- and 1,000-msec SOA was similar to that found for faces in Experiment 1, but for names there was some evidence of inhibition. To investigate the locus of the priming effect with faces, in Experiment 3 the effect of degrading face targets was examined. An interaction between stimulus quality and semantic priming was observed, suggesting that the locus of the facilitation might lie at a relatively early stage in face processing. The results of these experiments illustrate further similarities between the processing of faces and verbal materials (cf. Bruce 1979, 1981).     

The indirect effects of emotion regulation on the association between attachment style,depression, and meaning made among undergraduates who experienced stressful events

Undergraduates frequently report exposure to stressful life events which may negatively impact mental health. The current study examined associations among attachment style, depression, and meaning made, and tested both direct effects and indirect effects through emotion regulation difficulties. Undergraduates (N?=?336) who reported having experienced stressful and/or potentially traumatic events completed measures through an online survey. More than half of participants (64%) were female, with a mean age of 19.26 years. In both models, higher attachment anxiety and higher attachment avoidance were significantly associated with greater difficulties with accessing emotion regulation strategies, which in turn were related to higher depression symptom severity and lower meaning made. Lack of emotional awareness also partially explained the associations between attachment avoidance and outcomes in both models. Difficulties in engaging in goal-directed behavior partially explained the associations between attachment anxiety and meaning made, but not depression symptom severity. Our results suggest certain emotion regulation strategies may be key mechanisms through which individuals with high attachment anxiety or avoidance may reduce the potential negative mental health impact that stressful life events may have.     

Psychological and neurological predictors of abusive supervision

Although the negative effects of abusive supervision are well documented, less is known about the individual differences that drive supervisors to be abusive. We use a self‐control perspective to understand the unique roles of both psychological and neurological characteristics of supervisors in the prediction of abusive behavior. Specifically, we find a positive relationship between narcissism and abusive supervision, whereas political skill and intrinsic neurological connectivity in executive control regions of the brain negatively relate to abusive supervision. Our results further show that the relationship between narcissism and abusive supervision diminishes for those who are strong in terms of political skill. In addition, neurological executive control moderates the relationship between political skill and abusive behavior. When connectivity in executive control regions of the brain is lower, political skill becomes a more important factor in reducing the display of abusive behavior. Overall, we demonstrate how combinations of characteristics (both psychological and neurological) can provide a more in‐depth understanding of the emergence of abusive supervision.     

Social Function and Autism Spectrum Disorder in Children and Adults with Neurofibromatosis Type 1: a Systematic Review and Meta-Analysis

In light of the proliferation of recent research into social function in neurofibromatosis type 1 (NF1), a systematic review and meta-analysis is required to synthesise data and place findings within the context of a theoretical framework. This paper reviews findings from research into social function and autism spectrum disorder (ASD) in children and adults with NF1 and integrates these findings with the Socio-Cognitive Integration Abilities Model (SOCIAL). It also critically appraises links between social outcomes, internal and external factors moderating social functioning, cognitive domains implicated in social functioning, and underlying neural pathology in NF1. A systematic literature search conducted in MedLine (Ovid), PsycINFO (Ovid), Embase (Ovid), and PubMed electronic databases yielded 35 papers that met inclusion criteria for the systematic review. Out of these papers, 22 papers provided sufficient data for meta-analysis. Findings from this review and meta-analysis provide evidence that children and adults with NF1 exhibit significantly higher prevalence and severity of social dysfunction and ASD symptomatology. To date, very few studies have examined social cognition in NF1 but results indicate the presence of both perceptual and higher-level impairments in this population. The results of this review also provide support for age, gender, and comorbid ADHD as moderating factors for social outcomes in NF1. Suggestions for future research are offered to further our understanding of the social phenotype in NF1 and to facilitate the development of targeted interventions.     

ERPs reveal similar effects of social gaze orienting and voluntary attention, and distinguish each from reflexive attention

Spatial attention can be reflexively captured by a physically salient stimulus, effortfully directed toward a relevant location, or involuntarily oriented in the direction of another person's gaze (i.e., social gaze orienting). Here, we used event-related potentials to compare the effects of these three types of orienting on multiple stages of subsequent target processing. Although gaze orienting has been associated more strongly with reflexive capture than with voluntary attention, the present data provide new evidence that the neural effects of social gaze orienting are markedly different from the effects of reflexive attentional capture by physically salient stimuli. Specifically, despite their similar behavioral effects, social gaze orienting and reflexive capture produce different effects on both early sensory processing (~120 ms; P1/N1 components) and later, higher-order processing (~300 ms; P3 component). In contrast, the effects of social gaze orienting were highly similar to those of voluntary orienting at these stages of target processing.     

Perceptual categories and the computation of “grandmother”

Abstract

Recent theoretical approaches to understanding face recognition have used converging evidence from studies of normal face processing, everyday errors and patterns of neuropsychological impairment to suggest how different face processing modules are related to each other. This paper disuses four issues that arise from this body of work. These concern the nature of representations involved in face recognition, the existence of parallel pathways for processing different types of information, the relationship between recognition and awareness, and the question of how faces become familiar. Current research provoked by these issues is reviewed in the paper and suggestions are made about the ways in which such research will help refine theories of face processing.
