The role of stimulus comparison in human perceptual learning: effects of distractor placement

Within-subjects procedures were used to assess the influence of stimulus comparison on perceptual learning in humans. In Experiment 1, participants received intermixed (A, A', A, A',…) or blocked (B, B,…, B', B',…) exposure to pairs of similar female faces. In a subsequent same/different discrimination task, participants were more accurate when the test involved A and A' than when it involved B and B' (or novel faces: C and C'). This perceptual learning effect was reduced by placing a visual distractor (*: either another face or a checkerboard) between successive presentations of the faces during the exposure stage (e.g., A - * - A'). The attenuation of the intermixed versus blocked difference was particularly marked when faces were used as the distractor. In Experiment 2, this reduction in perceptual learning was more marked when * was positioned between the pairs of intermixed faces (i.e., A - * - A') than when it preceded and succeeded those faces (i.e., * - A - A' - *). These results provide the first direct evidence that the opportunity to compare stimuli plays a causal role in supporting perceptual learning. They also support the specific view that perceptual learning reflects an interaction between a short-term habituation process, that ordinarily biases processing away from the frequently presented common elements and toward their less frequently presented unique elements, and a long-term representational process that reflects this bias.     

Teaching Tradition: Diverse Perspectives on the Pilot Urban American Indian Traditional Spirituality Program

Many urban American Indian community members lack access to knowledgeable participation in indigenous spiritual practices. And yet, these sacred traditional activities remain vitally important to their reservation‐based kin. In response, our research team partnered with an urban American Indian health center in Detroit for purposes of developing a structured program to facilitate more ready access to participation in indigenous spiritual knowledge and practices centered on the sweat lodge ceremony. Following years of preparation and consultation, we implemented a pilot version of the Urban American Indian Traditional Spirituality Program in the spring of 2016 for 10 urban AI community participants. Drawing on six first‐person accounts about this program, we reflect on its success as a function of participant meaningfulness, staff support, mitigated sensitivities, and program structure. We believe that these observations will enable other community psychologists to undertake similar program development in service to innovative and beneficial impacts on behalf of their community partners.     

Correspondence of children's anticipated vocations, perceived competencies, and interests: Results from an Italian sample

Relations among anticipated vocations, self-assessments of competence, and interests in sample of 190 Italian children were examined. Children were asked what activities they liked, those they thought they were good at, and what job they expected when they grew up. The responses were coded into RIASEC Holland codes and agreement across the three questions was examined using kappa statistics. Results indicated that there was no relation between anticipated occupations and either interest or perceived competence. Thus, these anticipated occupations appear to be based on unrealistic criteria and the validity of studying such early expressions of interest is questionable. Conversely, results demonstrated a correspondence between interest and competence and this correspondence was similar for boys and girls and increased with age.     

A Case Series of Family-Based Therapy for Weight Restoration in Young Adults with Anorexia Nervosa

This case series aims to examine the preliminary efficacy, acceptability and feasibility of Family-Based Treatment to promote weight restoration in young adults with anorexia nervosa. Four young adults with sub/threshold anorexia nervosa were provided 11–20 sessions of Family-Based Treatment for young adults with pre-, post- and follow-up assessments. At post- and follow-up, 3/4 participants were in the normal weight range, 3/4 were in the non-clinical range on the Eating Disorders Examination and reported being not/mildly depressed. At post-treatment, 2/4 were in the good psychosocial functioning range and by follow-up, 3/4 were in this range. These results suggest that Family-Based Treatment for young adults with anorexia nervosa is a promising treatment.     

Billing for Medical Genetics and Genetic Counseling Services: A National Survey

In January 2007 the American Medical Association added a new Current Procedural Terminology® (CPT) code, 96040, for “Medical Genetics and Genetic Counseling Services.” In order to identify the impact of having this new code and to identify issues with implementation of the code, the National Society of Genetic Counselors (NSGC) CPT® Working Group surveyed NSGC members using an internet-based survey tool. The majority of respondents (94%) reported being aware of the new code and over half of the respondents (69%) said they were billing for genetic counseling. Approximately 24% of those billing reported using 96040. Many facilities are not using this code and the reported success of billing using 96040 is highly varied. Continued education may be beneficial to encourage reimbursement for 96040 and follow up is needed to assess the ongoing implementation and impact of the new CPT® code.     

Clericalism: Enabler of Clergy Sexual Abuse

Sexual abuse by Catholic clergy and religious has become the greatest challenge facing Catholicism since the Reformation. Violations of clerical celibacy have occurred throughout history. The institutional church remains defensive while scholars in the behavioral and social sciences probe deeply into the nature of institutional Catholicism, searching for meaningful explanations for the dysfunctional sexual behavior. Clericalism which has traditionally led to deep-seated societal attitudes about the role of the clergy in religious and secular society, explains in part why widespread abuse has apparently been allowed. Clericalism has a profound emotional and psychological influence on victims, church leadership, and secular society. It has enabled the psychological duress experienced by victims which explains why many have remained silent for years. It has also inspired societal denial which has impeded many from accepting clergy sexual abuse as a serious and even horrific crime. Thomas P.

Agency and observation in knowledge of one's own thinking

This essay addresses the question how we know our conscious thinking. Conscious thinking typically takes the form of a series of discrete episodes that constitute a complex cognitive activity. We must distinguish the discrete episodes of thinking in which a particular content is represented in phenomenal consciousness and is present “before the mind's eye” from the extended activities of which these episodes form a part. The extended activities are themselves contentful and we have first‐person access to them. But because their content is not represented in phenomenal consciousness, this access cannot be broadly observational. Instead, I argue, it is agential. Furthermore, that extended activities are intentional explains the possibility of a nonobservational form of introspective access to the discrete episodes in consciousness.     

Identifying Systematic Disobedience in Milgram's Obedience Experiments: A Meta-Analytic Review

ABSTRACT— A meta-analysis of data from eight of Milgram's obedience experiments reveals previously undocumented systematicity in the behavior of disobedient participants. In all studies, disobedience was most likely at 150 v, the point at which the shocked "learner" first requested to be released. Further illustrating the importance of the 150-v point, obedience rates across studies covaried with rates of disobedience at 150 v, but not at any other point; as obedience decreased, disobedience at 150 v increased. In contrast, disobedience was not associated with the learner's escalating expressions of pain. This analysis identifies a critical decision point in the obedience paradigm and suggests that disobedient participants perceived the learner's right to terminate the experiment as overriding the experimenter's orders, a finding with potential implications for the treatment of prisoners.
