Interference resolution in face perception and name retrieval

Selective retrieval is a rather difficult task, and especially so when one attempts to retrieve personal representations such as faces or names. Retrieval of memories under strong competition conditions is pervasive in human memory and some have suggested that inhibitory control is used to overcome interference between competing stimuli. In the present study, we used the retrieval practice paradigm to investigate if competition among personal representations (such as facial features and names) is also resolved by inhibitory mechanisms. This question is theoretically relevant, since personal representations have been said to have a special status on cognition. Moreover, some models of face recognition assume that interference can arise between different representations, but that this interference would be automatically and rapidly solved, with no need for a controlled inhibitory mechanism to act. In two experiments we showed RIF for facial features and familiar names, but only when participants had to actively retrieve some information. This suggests that personal information is subject to mechanisms of inhibitory control, which could help explain everyday life difficulties in processes such as face feature recognition or name retrieval.     

Neural events in the reinforcement contingency

When neural events are analyzed as stimuli and responses, functional relations among them and among overt stimuli and responses can be unveiled. The integration of neuroscience and the experimental analysis of behavior is beginning to provide empirical evidence of involvement of neural events in the three-term contingency relating discriminative stimuli, responses, and consequences. This paper is aimed at highlighting exemplar instances in the development of this issue. It has long been known that the electrical stimulation of certain cerebral areas can have a reinforcing function. Extraordinary technological advances in recent years show that neural activity can be selected by consequences. For example, the activity of in vitro isolated neurons that receive dopamine as a reinforcer functions as a cellular analogue of operant conditioning. The in vivo activity of populations of neurons of rats and monkeys can be recorded on an instant-to-instant basis and can then be used to move mechanical arms or track a target as a function of consequences. Neural stimulation acts as a discriminative stimulus for operant responses that are in turn maintained by neural consequences. Together with investigations on the molecular basis of classical conditioning, those studies are examples of possibilities that are being created for the study of behavior-environment interactions within the organism. More important, they show that, as an element in the three-term contingency, neural activity follows the same laws as other events.     

The Perfectionism Cognitions Inventory: Psychometric Properties and Associations with Distress and Deficits in Cognitive Self-management

Two studies were conducted to examine the psychometric properties and correlates of the Perfectionism Cognitions Inventory (PCI) when administered to clinical samples. The PCI is a 25-item measure of automatic thoughts with themes involving perfectionism and beliefs that perfection should be attained. Analyses indicated that the PCI is unidimensional and it has adequate internal consistency. Correlational analyses confirmed that the PCI is associated with psychological distress and deficits in cognitive self-management, including lack of self-reinforcement, lack of a positive self-focus, and perfectionistic inflexibility. Moreover, tests of incremental validity revealed that the PCI accounts for unique variance in levels of anxiety and depression symptoms after removing variance attributable to trait perfectionism dimensions. Overall, the findings suggest that automatic thoughts involving perfectionistic themes can be assessed in a reliable and valid manner in clinical samples. Moreover, it is important to assess perfectionism cognitions as a supplement to trait perfectionism measures when evaluating the role of perfectionism in psychological distress and associated deficits in cognitive self-control. This research was supported by major research grants from Health Canada and the Social Sciences and Humanities Research Council (SSHRC) of Canada to the first two authors, and a Canada Research Chair in Personality & Health awarded to the first author. The fourth author, Thomas Martin, is now deceased and this paper is dedicated to his memory.     

Semantic priming effects from single words in a lexical decision task

The present research examines the semantic priming effects of a centrally presented single prime word to which participants were instructed to either "attend and remember" or "ignore". The prime word was followed by a central probe target on which the participants made a lexical decision task. The main variables manipulated across experiments were prime duration (50 or 100 ms), the presence or absence of a mask following the prime, and the presence (or absence) and type of distractor stimulus (random set of consonants or pseudowords) on the probe display. There was a consistent interaction between the instructions and the semantic priming effects. Relative to the "attend and remember" instruction, an "ignore" instruction produced reduced positive priming from single primes presented for 100 ms, irrespective of the presence or absence of a prime mask, and regardless of whether the probe target was presented with or without distractors. Additionally, reliable negative priming was found from ignored primes presented for briefer durations (50 ms) and immediately followed by a mask. Methodological and theoretical implications of the present findings for the extant negative priming literature are discussed.     

Are we there yet? A review of gender comparisons in three behavioral journals through the 20th century

Despite overwhelming evidence that gender plays a significant role in the course of numerous psychological disorders, researchers have historically neglected to address gender similarities and differences in their research. Previous reviews of the psychological literature have indicated that personality, psychotherapy, and behavioral psychology journals have published few studies that focus on gender comparisons. The current review examined published articles in three prominent behavioral psychology journals—Behavior Therapy, Behavior Modification, and Behaviour Research and Therapy—from their inception through 2001. Raters coded each article (N = 4,635) for gender content in the title or abstract, analyses of gender differences, and discussion of gender. Overall, very few articles focused on gender content in the title, abstract, or discussion or analyzed data by gender. Implications of these results and suggestions for enhancing attention to gender comparisons are discussed.     

Perceptions of ambiguously unpleasant interracial interactions: a structural equation modeling approach

Despite a general consensus in the United States that overtly racist acts are unacceptable, many ambiguous situations in everyday life raise questions of whether racism has influenced a person's behavior in an interracial encounter. The authors of the present study sought to (a) examine simultaneously an array of variables thought to be related to perceived racism and (b) investigate how the contribution of these variables may differ with respect to the asymmetry hypothesis, which suggests that acts of discrimination from a dominant person toward a subordinate person will be viewed as more biased than if the situation were reversed. The authors used a dual structural equation modeling approach. Results indicated that ethnic identity significantly predicted perceived racism. In addition, the extent to which cognitive interpretation style significantly predicted perceived racism depended on the ethnicity of participants involved in the interaction.     

Ministers’ Perceptions of Depression: A Model to Understand and Improve Care

While depression is a significant worldwide health problem, fewer than half of individuals seek care. Faith-based communities may play an important role in improving the knowledge of and linkage to depression care. Focus groups of Caucasian and African-American clergy were conducted to explore these issues. Using a grounded theory approach five themes emerged, including explanatory models of depression, barriers and facilitators to care, and recommendations for involving religious communities. A model of depression care pathways was constructed that integrates secular and spiritual approaches. The findings highlight the need for targeted interventions to build trust between clergy and mental health professionals. Teresa L.

Clinical perspectives on the combination of D-cycloserine and cognitive-behavioral therapy for the treatment of anxiety disorders

In a particular success for translational research agendas, characterization of the neuronal circuits underlying fear extinction, and basic research in animal extinction paradigms, has led to intervention studies examining the use of D-cycloserine (DCS) to enhance therapeutic learning from exposure-based cognitive-behavioral therapy (CBT). In this article, we review these intervention studies, and discuss DCS augmentation of CBT relative to more traditional combination-treatment strategies in the treatment of anxiety disorders. We offer an accounting, based on evidence for internal context effects, of current limitations in the combination of antidepressant or benzodiazepine medications with CBT and discuss the advantages of isolated-dosing strategies with DCS relative to these limitations. This strategy is contrasted with the chronic-dosing applications of DCS for schizophrenia and Alzheimer's disease, and future directions for isolated-dosing strategies are discussed.     

Identifying and analyzing the construction and effectiveness of offensive plays in basketball by using systematic observation

In the field of sports research, there is a growing need for the rigorous collection of data that provide empirical evidence about the complex reality they refer to. Although sports psychology research has advanced considerably in recent years, in both extent and quality, one area of research that remains relatively unexplored is the dynamics of the sports group and the influence of the group on its members (George & Feltz, 1995; Widmeyer, Brawley, & Carron, 1992). Key aspects in this regard include the presence of regularities that are not detectable through visual inference or traditional methods of data analysis, the lack of standard observation instruments, and, assuming priority, the need to develop powerful, computerized coding systems, all of which must form part of an approach that is suitable for natural and habitual contexts. The present study is part of a broader research project concerning ACB teams (first Spanish basketball division) and considers the interaction context before teams try to score (where this is understood as how teams create scoring opportunities) as the core aspect that links team play. This investigation proposes a new model of analysis for studying the effectiveness and construction of offensive basketball plays in order to identify their outcomes, thus providing coaches with an important device for improving or consolidating them.     

Familiarity impacts person perception

We investigated the effects of familiarity on person perception. We predicted that familiarity would increase non‐analytic processing, reducing attention to and the impact of individuating information, and increasing the impact of category labels on judgments about a target person. In two studies participants read either incriminating or exculpatory individuating information about a defendant in a criminal case and made judgments of guilt. In Study 1, participants were subliminally exposed to the defendant's photo, another matched photo, or no photo before seeing the evidence. Participants familiar with the defendant's photo both processed and used the individuating information less. In Study 2, participants were subtly made familiar or not with the incriminating and exculpatory information itself, and the defendant was described either as a priest or as a skinhead. Familiarity with the information reduced attention to its content and also tended to increase reliance on category information in guilt judgments. Copyright © 2006 John Wiley & Sons, Ltd.
