Influence of attended repetition trials on negative priming in younger and older adults

A lengthened response time when a distractor becomes a target, called negative priming, is an undisputed phenomenon in selective attention, yet just what the underlying mechanism responsible for negative priming is has not been resolved. In this study, the proportion of attended repetition trials was manipulated in order to test the predictions of three theories that have been proposed for explaining spatial negative priming: distractor suppression (e.g., Tipper, 1985), episodic memory retrieval (e.g., Neill, Valdes, &; Terry, 1995), and novelty bias (e.g., Milliken, Tipper, Houghton, &; Lupiáñez, 2000). The results supported the proposal that a novelty bias, which is flexible and can be overridden, is the primary mechanism responsible for priming in spatial tasks. Memory retrieval obscured the novelty bias for target processing, was more selective in older adults, and did not affect distractor processing. Novelty bias and distractor suppression may share the same inhibitory attentional mechanism.     

Navigating Social Class Roles in Community Research

This paper describes the first author's attempt to collect data in a homeless shelter without attending to her role in the social class hierarchy of the organization. The author's egalitarian approach towards the homeless clients, and her lack of involvement in "staff-only" activities, transgress the social class norms within the organizational structure. While the author is successful in gaining the trust of the homeless clients, her approach alienates shelter staff, especially those in the higher echelons of the social hierarchy. The concepts of classism, world views, and Social Identity Theory, are utilized to discuss the dilemma faced by researchers who want to challenge, or work outside, a setting's status quo.     

Processing emotional facial expressions: The role of anxiety and awareness

In this paper, the role of self-reported anxiety and degree of conscious awareness as determinants of the selective processing of affective facial expressions is investigated. In two experiments, an attentional bias toward fearful facial expressions was observed, although this bias was apparent only for those reporting high levels of trait anxiety and only when the emotional face was presented in the left visual field. This pattern was especially strong when the participants were unaware of the presence of the facial stimuli. In Experiment 3, a patient with right-hemisphere brain damage and visual extinction was presented with photographs of faces and fruits on unilateral and bilateral trials. On bilateral trials, it was found that faces produced less extinction than did fruits. Moreover, faces portraying a fearful or a happy expression tended to produce less extinction than did neutral expressions. This suggests that emotional facial expressions may be less dependent on attention to achieve awareness. The implications of these results for understanding the relations between attention, emotion, and anxiety are discussed.     

Self-control skills and negative emotional state: a focus on hostility

The self-control theory of psychopathology has contributed to the understanding and treatment of unipolar depression. This paper explores the relationship between self-control skills as measured by the Frequency of Self-reinforcement Questionnaire and other negative emotional states, with a focus on hostility. In Study 1, scores on the Brief Symptom Inventory were inversely related to self-control skills among a sample of 53 college students, suggesting potential generalizability of the theory. In Study 2, self-control skills were inversely related to hostility, anger, and aggression among a sample of 68 college students. The role of self-control skills in the regulation of hostility deserves further investigation.     

Attentional Bias for Threat: Evidence for Delayed Disengagement from Emotional Faces

The present paper reports three new experiments suggesting that the valence of a face cue can influence attentional effects in a cueing paradigm. Moreover, heightened trait anxiety resulted in increased attentional dwell-time on emotional facial stimuli, relative to neutral faces. Experiment 1 presented a cueing task, in which the cue was either an "angry", "happy", or "neutral" facial expression. Targets could appear either in the same location as the face (valid trials) or in a different location to the face (invalid trials). Participants did not show significant variations across the different cue types (angry, happy, neutral) in responding to a target on valid trials. However, the valence of the face did affect response times on invalid trials. Specifically, participants took longer to respond to a target when the face cue was "angry" or "happy" relative to neutral. In Experiment 2, the cue-target stimulus onset asynchrony (SOA) was increased and an overall inhibition of return (IOR) effect was found (i.e., slower responses on valid trials). However, the "angry" face cue eliminated the IOR effect for both high and low trait anxious groups. In Experiment 3, threat-related and jumbled facial stimuli reduced the magnitude of IOR for high, but not for low, trait-anxious participants.These results suggest that: (i) attentional bias in anxiety may reflect a difficulty in disengaging from threat-related and emotional stimuli, and (ii) threat-related and ambiguous cues can influence the magnitude of the IOR effect.
