From sensory processes to conscious perception

In recent years, cognitive neuroscientists have began to explore the process of how sensory information gains access to awareness. To further probe this process, event-related functional magnetic resonance imaging (fMRI) was used while testing subjects with a paradigm known as the "attentional blink." In this paradigm, visually presented information sporadically fails to reach awareness. It was found that the magnitude and time course of activation within the anterior cingulate (BA 32), medial prefrontal cortex (BA 9), and frontopolar cortex (BA 10) predicted whether or not information was consciously perceived during the critical period for the attentional blink. These results are discussed in light of a neural framework for conscious processing.     

Are there capacity limitations in symmetry perception?

Previous researchers have proposed that there are two types of symmetry detection: one based on crude preattentive symmetry judgments and another based on detailed scrutiny of individual parts (Barlow & Reeves, 1979; S. E. Palmer & Hemenway, 1978; Royer, 1981). Four experiments were conducted to examine capacity limits in different symmetry judgments. Observers were required to discriminate between random patterns and approximate symmetry (Experiments 1 and 3) or between perfect and approximate symmetry (Experiments 2 and 4). The patterns were divided into two sets of dots, presented either simultaneously or successively. A comparison of accuracy under these two presentation conditions suggested that symmetry detection involves an analysis that is spatially parallel but coarse, regardless of either task difficulty or task type (detecting symmetry vs. detecting asymmetry).     

Religiousness and depression: evidence for a main effect and the moderating influence of stressful life events

The association between religiousness and depressive symptoms was examined with meta-analytic methods across 147 independent investigations (N = 98,975). Across all studies, the correlation between religiousness and depressive symptoms was -.096, indicating that greater religiousness is mildly associated with fewer symptoms. The results were not moderated by gender, age, or ethnicity, but the religiousness-depression association was stronger in studies involving people who were undergoing stress due to recent life events. The results were also moderated by the type of measure of religiousness used in the study, with extrinsic religious orientation and negative religious coping (e.g., avoiding difficulties through religious activities, blaming God for difficulties) associated with higher levels of depressive symptoms, the opposite direction of the overall findings.     

Cognitive-behavioral therapy for social anxiety disorder: supporting evidence and future directions

The present paper examines the role of cognitive-behavioral therapy (CBT) in the treatment of social anxiety disorder (SAD). A cognitive-behavioral model of SAD is first presented. Different modalities of CBT for SAD are then described, including exposure, cognitive restructuring, relaxation training, and social skills training, and evidence supporting their efficacy is reviewed. The comparative and combined impact of CBT and pharmacotherapeutic interventions is also explored. CBT appears to be an efficacious treatment for SAD. However, the overall efficacy CBT may be increased by closer examination of the active ingredients of treatment. Such analyses may also enable more successful integration of the different CBT techniques and of CBT and pharmacotherapy in the treatment of SAD.     

Rhetorical Unity and Social Division: A Longitudinal Study of Change in Australian Self-Stereotypes

This paper examines the impact of social division associated with the emergent "race debate" in Australia (and the so-called "Hanson phenomenon") on the consensus of Australian students' stereotypes of their national ingroup. It compares the stereotypes held by a sample of students in 1997 ( N = 20) with those revealed in studies conducted from 1992 onwards ( N = 102). Results provide strong evidence that stereotype consensus was reduced in the current phase of research and post-testing also indicates that participants themselves interpreted this as being the product of political change in Australian society. The findings are consistent with the argument that stereotypes are sensitive to changes in intergroup and intragroup relations, and that they respond to the reality of social division rather than to the rhetoric of unity.     

Witnesses in action: the effect of physical exertion on recall and recognition

Understanding memory performance under different operational conditions is critical in many occupational settings. To examine the effect of physical exertion on memory for a witnessed event, we placed two groups of law-enforcement officers in a live, occupationally relevant scenario. One group had previously completed a high-intensity physical-assault exercise, and the other had not. Participants who completed the assault exercise showed impaired recall and recognition performance compared with the control group. Specifically, they provided significantly less accurate information concerning critical and incidental target individuals encountered during the scenario, recalled less briefing information, and provided fewer briefing updates than control participants did. Exertion was also associated with reduced accuracy in identifying the critical target from a lineup. These results support arousal-based competition accounts proposing differential allocation of resources under physiological arousal. These novel findings relating to eyewitness memory performance have important implications for victims, ordinary citizens who become witnesses, and witnesses in policing, military, and related operational contexts.     

The effects of prior knowledge on the encoding of episodic contextual details

A positive relationship between prior knowledge and item memory is a consistent finding in the literature. In the present study, we sought to determine whether this relationship extends to episodic details that are present at the time of encoding, namely source memory. Using a novel experimental design, we were able to show both between- and within-subjects effects of prior knowledge on source memory. Specifically, the results revealed that the degree of prior knowledge positively predicted memory for source specifying contextual details. In addition, by including two conditions in which attention was divided either at encoding or retrieval, we were able to show that prior knowledge influences memory by affecting encoding processes. Overall, the data suggest that a priori knowledge within a specific domain allows attentional resources to be allocated toward the encoding of contextual details.     

Preparing Psychologists in Academic Health Centers for the Rapidly Changing Health Care Environment

The Association of Psychologists in Academic Health Centers (APAHC) convened its 5th National APAHC Conference in Boston March 3–5 2011. The conference and its theme, “Preparing Psychologists for a Rapidly Changing Health Care Environment,” brought psychologists from academic health centers together to examine how psychology can adapt to and help lead health care efforts in the face of health care reform. This paper reports on the conference and introduces the special issue of JCPMS that is dedicated to the conference. The conference theme is framed in the historical context of the four national conferences that preceded it. In examining the focus and topics of the preceding conferences, recurrent themes are identified and progress in certain areas is highlighted.     

The internal adaptation processes of professional boxers during the Showtime Super Six Boxing Classic: A qualitative thematic analysis

ObjectivesThe Super Six World Boxing Classic was conceived by Showtime Sports to feature the best six professional boxers in the super middleweight division (168 pounds) throughout a modified round robin tournament. The objective was to explore the adaptation and mal-adaptation processes of the tournament's original six tournament participants over time.DesignMedia data in the form of documentary episodes (n = 12 episodes, ～30 min each from the foregoing source were transcribed verbatim. Data included athletes' responses prior to their first bout and as each progressed or was eliminated. Boxers' post-bout explanations were also included.MethodThe original six contestants (mean age = 28.8 years at tournament start) from the tournament, with a record of 157 wins and 4 losses, were included within the project. Data were analyzed via thematic analysis (see Braun & Clarke, 2006).ResultsThe following themes were identified: (a) pre-conditions: moving into the tournament (subthemes: positive anticipation, uncertainty), (b) outcomes: moving through the tournament (subthemes: tournament progression, tournament regressions), and (c) consequences: moving out of the tournament (sub-themes: responses of the defeated, the king's adaptation).ConclusionsThis study highlights the adaptation processes of the six tournament contestants, demonstrating how one athlete adapted successfully and became champion through personal focus. The remaining athletes lost at least once, with pre-bout adaptation processes suggesting performance regression. These findings add to the adaptation literature, further contextualizing how adaptation meanings change and unfold over time.
