RESUMO

Research has documented neurophysiological indicators of anticipation (Stimulus Preceding Negativity [SPN]) and perception (Late Positive Potential [LPP]) of threat, yet little is known as to how self-focused attention manipulations influence emotion processing within the context of cued picture viewing. With self-referent attention moderating attention to external stimuli, it is necessary to document how self-focused attention impacts attention and the ability to emotionally process external threat. The goal of the present study was to evaluate the impact of self-focused attention on the anticipation and perceptual processing of unpleasant pictures within a cued-picture viewing paradigm among 33 participants. Overall, the results suggest that the self-focused attention manipulations disrupted anticipation but not processing of pictures, as indexed by the SPN and LPP respectively. Self-focused attention appears to disrupt the preparatory attention for upcoming unpleasant stimuli, potentially through loading cognitive resources or activation of associative defensive responding. Collectively, these findings demonstrate the impact of self-focused attention within the context of emotional picture processing and suggest further areas of investigation.

RESUMO

Models of social anxiety propose that negative self-imagery is a maintenance factor of psychopathology, yet the mechanisms of this relationship are unclear. One proposed mechanism is attention towards self-images. However, self-image creation does not occur in isolation and is likely influenced by other mechanisms, such as anticipatory processing (AP). The current study aimed to investigate how trait social anxiety and AP influence motivated attention during self-imagery (i.e., late-positive potential; LPP). Participants (N = 40) with a mean age of 18.95 (SD = 1.22) completed AP manipulations and a self-imagery task. Results revealed that participants with high levels of social anxiety who engaged in AP demonstrated blunted LPP activity in the late time window (6000-10,000 ms) relative to those who engaged in Distraction. These results suggest that motivated attention towards self-imagery may be impacted by anticipatory processing, but less influenced by the valence of self-imagery. Given previous research has been limited in methodology, this study expands upon current research by documenting the neural mechanisms of self-imagery manipulations within social anxiety.

RESUMO

The Social Anxiety Questionnaire (SAQ) is a 10-item measure of social anxiety developed to comprehensively and concisely target the mechanisms described in Clark and Wells' model of social anxiety and address the breadth of social anxiety symptoms which may not all be encompassed in existing questionnaires. The aim of the current studies is to independently investigate the factor structure of the SAQ (i.e., Study 1 and 2) and determine its predictive validity and utility (i.e., Study 3 and 4). Data were collected across 4 studies to evaluate the factor structure and utility. Overall, the results suggest that a total summed score of the SAQ appeared to capture unique aspects of social anxiety that may not be captured using a single measure and appears to provide utility in experimental manipulations of theoretical maintenance factors. The current study was limited by a convenience sample and future research should continue to document the psychometric properties and clinical utility of this novel measure of social anxiety. The SAQ may show promise in both correlational and experimental research but future research should consider further evaluation of its utility.

RESUMO

Investigations of fear conditioning have recently begun to evaluate contextual factors that affect attention-related processes. However, much of the extant literature does not evaluate how contextual fear learning influences neural indicators of attentional processes during goal-directed activity. The current study evaluated how early attention for task-relevant stimuli and conflict monitoring were affected when presented within task-irrelevant safety and threat contexts after fear learning. Participants (N = 72) completed a Flanker task with modified context before and after context-dependent fear learning. Flanker stimuli were presented in the same threat and safety contexts utilized in the fear learning task while EEG was collected. Results indicated increased early attention (N1) to flankers appearing in threat contexts and later increased neural indicators (P2) of attention to flankers appearing in safety contexts. Results of this study indicate that contextual fear learning modulates early attentional processes for task-relevant stimuli that appear in the context of safety and threat. Theoretical and clinical implications are discussed.

RESUMO

Attentional control has grown in importance within theoretical and predictive models of psychopathology over past decades. The Attentional Style Questionnaire (ASQ) is a novel measure of internal and external attentional control. However, no study has independently validated this questionnaire. Two studies assessed the factor structure for the ASQ within an English-speaking population (Study 1), evaluated the construct and content validity, and assessed incremental predictability (Study 2). Results of Study 1 observed two factors that could be characterised as distractibility/cognitive avoidance and focusing, whereas the original study had observed factors defined as internal and external. Results of Study 2 confirmed the factor structure of Study 1, in addition to providing evidence for the ASQ's predictability for anxiety, depression and worry behaviours above established measures of attentional control. Overall, these results indicated that the ASQ measures factors of attentional control which provides incremental utility for predicting psychopathology. Implications on psychopathology and discrepancies to previous findings are discussed.
