Constrained action selection in children with developmental coordination disorder

The effect of advance ('precue') information on short aiming movements was explored in adults, high school children, and primary school children with and without developmental coordination disorder (n=10, 14, 16, 10, respectively). Reaction times in the DCD group were longer than in the other groups and were more influenced by the extent to which the precue constrained the possible action space. In contrast, reaction time did not alter as a function of precue condition in adults. Children with DCD showed greater inaccuracy of response (despite the increased RT). We suggest that the different precue effects reflect differences in the relative benefits of priming an action prior to definitive information about the movement goal. The benefits are an interacting function of the task and the skill level of the individual. Our experiment shows that children with DCD gain a benefit from advance preparation in simple aiming movements, highlighting their low skill levels. This result suggests that goal-directed RTs may have diagnostic potential within the clinic.     

Prevalence and reporting of near-point binocular convergence and acuity vision deficits in potential research participants

Visual abilities at near-point distances of 200 self-reported normal vision college students were assessed. Results show that normal visual functioning with no deficits is the exception. The most common visual deficits observed involved binocular lateral posture and fusion convergence deficits. Binocular and monocular acuity deficits also had high prevalence rates, although not as prevalent as the binocular convergence deficits. In addition, 1,340 articles published in four major journals from the years 1997-2004 were examined to ascertain the extent to which authors report the visual capabilities of their participants. Reporting of research participant visual abilities by authors using visual stimuli in experiments appears to be lacking. The results are discussed in terms of the potential impact that visual deficits may have on results obtained in experiments in which visual stimuli are used and the importance of reporting the visual assessment tests and procedures used to assess the visual abilities of potential participants.     

Possession and Medicine in South Central India

Possession is a powerful and surprisingly prevalent belief system in many parts of the developing world. In India it is common for many reasons—isolation, illiteracy, polyglotism, lack of an adequate medical infrastructure, a need for hope. Possession, and the practice of exorcism, is more than just an explanatory system based on superstition and folk lore. It is also an important social structure and force that allows the integration of the sick into the community of the well, and facilitates a first albeit tentative step from the local community to the medical community. In many parts of India, health care delivery as well as social organization is through the practice of possession. Thus, the role and power of possession needs to be appreciated if one seeks to affect health care delivery in India, and further possession should be appreciated if one seeks to better understand how some of its forces might in fact be curative.     

The elements of emotion

I join the growing ranks of theorists who reject the terms of traditional debates about the nature of emotion, debates that have long focused on the question of whether emotions should be understood as either cognitive or somatic kinds of states. Here, I propose and defend a way of incorporating both into a single theory, which I label the “Integrated Representational Theory” of emotion (IRT). In Section 2 I begin to construct the theory, defining and explaining emotions in terms of three pieces of content: representations of (1) the emoter’s body, (2) something in the world, and (3) a relevance relation between the objects of these first two pieces of content. I describe four general advantages I think the IRT offers. Finally, in Section 3, I elucidate and defend my account by contrasting it with another, similar proposal: Barlassina and Newen’s Impure Somatic Theory. In so doing, I explain two additional advantages of my view: first, it supports a unified explanation of all types of emotional response; and second, it offers the best framework for explaining how the representational contents of an emotion are integrated.     

Development of a telephone-based intervention for support persons to help smokers quit

This study represents the first step toward systematic behavioral treatment development and pilot testing of a novel approach to smoking cessation that utilizes adults interested in helping someone to stop smoking (i.e., support persons) as the agent of change. The counselor manual for a telephone-based intervention for support persons was developed based on a previous clinic-based intervention. Social cognitive theory served as the conceptual basis for the intervention. Ten adult non-smoking females completed the treatment protocol, consisting of six 20 - 30-min sessions and written materials. The support person was the sole recipient of the professional intervention. Feedback was obtained from 8 of the 10 participants and all 4 telephone counselors 1 week post-treatment (week 10). Results indicate that the telephone-based intervention was feasible and acceptable to participants. The intervention was refined based on participant and counselor feedback and will be subsequently tested in a randomized pilot trial.     

Managing Child Behavior Problems in Children With Autism Spectrum Disorders: Utilizing Structural and Solution Focused Therapy With Primary Caregivers

Previous therapeutic models for modifying and managing problem behaviors in children with an Autism Spectrum Disorder have, typically, focused on working directly with the diagnosed child. The exclusion of other family member involvement in treatment displayed a need for creating a systemic model for managing children's problem behaviors. This model proposes Solution Focused Brief Therapy (SFBT) and Structural Family Therapy (SFT) with a focus on the caregivers of children with ASDs to reduce parental stress, increase parental self-efficacy, and ultimately begin to manage child behavior problems.
