Evidence for criterion shifts in visual perceptual learning: data and implications

Work on visual perceptual learning for contrast detection has shown that reliable decreases in detection thresholds are accompanied by reliable increases in false alarm rates (Wenger & Rasche, 2006). The present study assesses the robustness and replicability of these changes, demonstrating that they are independent of a variety of task demands (i.e., the specific method used for perceptual practice and threshold estimation) and the presence or absence of trial-by-trial feedback and that the source of the increases can be found in shifts in changes in sensitivity and in bias for detection, identification, or both. Although the increase in false alarm rates suggests a strategic shift in response criteria for detection, we demonstrate that there are multiple potential explanations, including explanations that do not require strategic shifts on the part of the observer. The empirical evidence and analysis of alternative explanations reinforce the inference that visual perceptual learning may involve more than changes in perceptual sensitivity and that cortical circuits beyond the primary visual areas may be involved.     

Standardized Human Pedigree Nomenclature: Update and Assessment of the Recommendations of the National Society of Genetic Counselors

In 1995, the Pedigree Standardization Task Force (PSTF) of the National Society of Genetic Counselors (NSGC) proposed a system of pedigree nomenclature. Recently, the PSTF (now called the Pedigree Standardization Work Group or PSWG) sought evidence that the published symbols met the needs of health professionals, were incorporated into health professional training and were utilized in publications. We searched PubMed and reference lists of select publications, reviewed the Instructions for Authors of several journals, searched the websites of professional societies, sought comment from the membership of the NSGC, and looked at recommendations and training practices of various health professional organizations. Many journals still do not cite specific standards for pedigrees, but those found cited the PSTF nomenclature. We did not find significant objections or alternatives to the 1995 nomenclature. Based on our review, we propose only a few minor stylistic changes to the pedigree symbols. The pedigree nomenclature of the NSGC is the only consistently acknowledged standard for drawing a family health history. We recommend regular and continued review of these pedigree standards to determine if additional symbols are needed to accommodate changes in clinical practice to ensure that the symbols continue to meet the needs of health professionals and researchers as well as adhere to evolving ethical and privacy standards. All health professionals, trainees, and researchers should be made aware of the utility of using a common pedigree nomenclature in clinical practice and publication. This will become particularly important as electronic medical records become more widely utilized.     

Brief Behavioral Therapy for Pediatric Anxiety and Depression: Piloting an Integrated Treatment Approach

Mood and anxiety disorders in youth are disabling, distressing, and prevalent. Furthermore, depression and anxiety frequently co-exist, may share several etiological factors, and respond to similar interventions. In this paper, we report preliminary results from a treatment adaptation project designed to condense existing cognitive behavioral therapy protocols for anxiety and depression to their core components and combine them into a brief, integrated treatment suitable for the broad population of internalizing youth seen in primary care. Specifically, we discuss: (a) the rationale for targeting anxiety and depression in pediatric primary care and the deployment-focused treatment development model; (b) the content of our behaviorally based treatment program; and (c) clinical outcomes of 2 sample cases with comorbid depression and anxiety.     

Developing Cognitive Behavioral Therapy to Prevent Depressive Relapse in Youth

Relapse rates for children and adolescents with major depressive disorder (MDD) range from 30% to 40% within 1 to 2 years after acute treatment. Although relapse rates are high, there have been relatively few studies on the prevention of relapse in youth. While acute phase pharmacotherapy has been shown to reduce symptoms rapidly in depressed youth, children and adolescents frequently report ongoing residual symptoms and often relapse following acute treatment. Recent adult trials have begun examining augmentation with psychosocial treatment after successful medication treatment to enhance medication response and prevent future relapse. This strategy has not yet been examined in youth with depression. Here we present initial efforts to develop a sequential, combination treatment strategy to promote rapid remission and to prevent relapse in depressed youth. We describe efforts to adapt CBT to prevent relapse (RP-CBT) in youth who respond to pharmacotherapy. The goals of RP-CBT include: preventing relapse, increasing wellness, and developing skills to promote and sustain well-being. We describe the rationale for, components of, and methods used to develop RP-CBT. The results from a small open series sample demonstrate feasibility and indicate that youth appear to tolerate RP-CBT well. A future test of the treatment in a randomized controlled trial is described.     

At the same time

The essay on Husserl’s phenomenology of touch in Derrida’s recent On Touching—Jean-Luc Nancy represents his only substantial re-engagement with Husserlian phenomenology to be published following the series of texts dating from the period marked by his Mémoire of 1955 through to the essay ‘Form and Meaning’ included in Margins (1972). The essay, devoted to some key sections of Husserl’s Ideas II, appears to break new ground in Derrida’s readings of Husserl, but in fact demonstrates a profound continuity with his earlier readings. In fact, I argue that this continuity is in a part an effect of Derrida’s ongoing commitment to the ‘methodology’ of deconstruction. I show how this commitment leads Derrida to conflate three separate distinctions within Husserl’s discussion, a conflation that obliges Derrida to misread the letter of Husserl’s text, and which, in turn, blinds him to a certain radical potentiality within Husserl’s phenomenology of sensibility.

Spatial knowledge of geographical globes: Evidence of vertical alignment effects

This study investigated human spatial memory of geographical globes. In two experiments, participants studied locations presented on a three‐dimensional globe. Subsequently, participants' knowledge of the locations was tested employing two types of pointing task. Directional judgments from imagined locations on the globe were performed either vertically through the ground (as if digging a straight tunnel between the locations) or horizontally along the surface of the globe (the shortest distance for an aircraft to fly to a given destination). In the vertical pointing task, judgments originating from imagined locations in the upper hemisphere were superior by comparison with those originating from imagined locations in the lower hemisphere. Performance in the horizontal pointing task was more variable, with a tendency for superior judgments originating from imagined locations in the lower hemisphere. The results provide evidence of a novel alignment effect involving vertical judgments.     

Functional relationships in the nuclear and extended family: A 16‐culture study

This study investigated the relationship between culture, structural aspects of the nuclear and extended family, and functional aspects of the family, that is, emotional distance, social interaction, and communication, as well as geographical proximity. The focus was on the functional aspects of family, defined as members of the nuclear family (mother, father, and their children) and the extended family (grandmother/grandfather, aunt/uncle, cousins). Sixteen cultures participated in this study, with a total number of 2587 participants. The first hypothesis, that the pattern of scores on the psychological measures and the behavioral outcomes are similar across cultures, an indication of cultural universality, was supported. The second hypothesis, that functional relations between members of the nuclear family and their kin are maintained in high‐affluent and low‐affluent cultures, and that differences in functional relationships in high‐ and low‐affluent cultures are a matter of degree, was also supported by the findings. The results suggest that it is less meaningful in cross‐cultural family studies to ask questions about the structure of the family, than to ask about the functional relationships between members of the nuclear family and their kin. In looking only at the nuclear family, one focuses only on those residing in the household, but ignores those important members of the extended family who may reside nearby and their significant relationships with the members of the nuclear family.     

Relationships Among Giving, Church Attendance, and Religious Belief: The Case of the Presbyterian Church (USA)

Using data from a survey of members and elders of the Presbyterian Church (USA), we estimate relationships among religious contributions, church attendance, and theological belief. Survey respondents indicated whether they were theologically conservative or liberal, and we hypothesized that the level and the composition of giving would be affected by theological belief. We found that conservative Presbyterians gave more in total, and gave more to the local church and to non-Presbyterian religious organizations than did more liberal Presbyterians, while more liberal Presbyterians gave more to secular charities than did conservative Presbyterians.
