Measuring the error of localization

We describe a procedure to measure the error of localization on the skin. The procedure, which provides for rapid measurement of the error of localization and rapid analysis of the data, uses a digitizing tablet interfaced with a computer. A photocopy of the part of the body to be tested is placed on the digitizing tablet. The subject localizes the stimulus by touching the pen of the digitizing tablet to the photocopy. The location of the pen contact is stored, and the error of localization is determined by the computer. A graphic representation of each subject’s test area can be stored. Both stimulus and response locations can be displayed on this graphic representation. The procedure also allows the same sites on the skin to be tested over a period of weeks or months.     

GENERALIZATION AND MAINTENANCE OF PRESCHOOL CHILDREN'S SOCIAL SKILLS: A CRITICAL REVIEW AND ANALYSIS

This paper summarizes the results of a retrospective review of generalization in the context of social skills research with preschool children. A review of studies from 22 journals (1976 to 1990) that assessed generalization as part of social interaction research provided information concerning the prevalence of studies that have assessed generalization, common practices concerning the production and assessment of generalization, and the overall success of obtaining generalization and maintenance of social behaviors. A comparison of the most and least successful studies, with respect to generalization, revealed some differences concerning the practices employed by studies within each group. Differences differentially related to the production of generalization are discussed and recommendations are provided to guide and support future research efforts.     

Music to the inner ears: Exploring individual differences in musical imagery

In two studies, we explored the frequency and phenomenology of musical imagery. Study 1 used retrospective reports of musical imagery to assess the contribution of individual differences to imagery characteristics. Study 2 used an experience sampling design to assess the phenomenology of musical imagery over the course of one week in a sample of musicians and non-musicians. Both studies found episodes of musical imagery to be common and positive: people rarely wanted such experiences to end and often heard music that was personally meaningful. Several variables predicted musical imagery, including personality, musical preferences, and positive mood. Musicians tended to hear musical imagery more often, but they reported less frequent episodes of deliberately-generated imagery. Taken together, the present research provides new insights into individual differences in musical imagery, and it supports the emerging view that such experiences are common, positive, and more voluntary than previously recognized.     

Towards a queer dharmology of sex

Lay practitioners of Buddhism, especially lesbian/gay/bisexual/transgender/queer persons, are given little guidance by the traditional Dharmology (Buddhist theology) of sex. The most extensive discussions are the detailed prohibitions in the monastic rule, which focus on the mechanics of sex rather than on love and relationships. What advice there is on sex for lay persons is either vague or over‐determined by its cultural context. Christianity, despite being homophobic and mistrustful of sex, has developed a positive attitude towards sex within heterosexual marriage. An investigation of this suggests a Dharmology of sex as relationship, based on central Buddhist doctrines such as interdependent arising. This Dharmology can be strengthened by queering it with reference to Harry Hay's notion that gay subject–subject consciousness is more compatible with Buddhist non‐duality than the hetero subject–object consciousness. It can be claimed, therefore, that Buddha Nature, and Buddhism itself, is queer.     

Consciousness avoided

In Consciousness Explained, Dennett systematically deconstructs the notion of consciousness, emptying it of its central and essential features. He fails to recognize the self‐intimating nature of experience, in effect reducing experiences to reports or judgments that so‐and‐so is the case. His information‐processing model of meaning is unable to account for semantics, the way in which speakers and hearers relate strings of symbols to the world. This ability derives ultimately from our animal nature as experiencers, though culturally supplemented in various ways. But Dennett, while successful in rebutting Cartesianism about the mind, fails to take into account our natural history. He claims descent from Wittgenstein in his philosophy of mind, but he shows awareness only of Wittgensteinian's demolition of the private object of experience and overlooks the equally Wittgensteinian theme of humans as products of nature.     

The spider does not always win the fight for attention: Disengagement from threat is modulated by goal set

Stimulus-driven preferential attention to threat can be modulated by goal-driven attention. However, it remains unclear how this goal-driven modulation affects specific attentional components implied in threat interference. We hypothesise that goal-driven modulation most strongly impacts delayed disengagement from threat. A spatial cueing task was used that disentangles delayed disengagement from attentional capture by tightly manipulating the locus of attention at the time of target onset. Different top-down goals were induced by instructing participants to identify bird/fish targets (Experiment 1) or spider/cat targets (Experiment 2) among animal non-targets. Delayed disengagement from a non-target spider was observed only when the spider was part of the target set, not when it was task-irrelevant. This corroborates evidence that threat stimuli do not necessarily override goal-driven attentional control and that extended processing of threatening distractors is not obligatory.     

Using diffusion models to understand clinical disorders

Sequential sampling models provide an alternative to traditional analyses of reaction times and accuracy in two-choice tasks. These models are reviewed with particular focus on the diffusion model (Ratcliff, 1978) and how its application can aid research on clinical disorders. The advantages of a diffusion model analysis over traditional comparisons are shown through simulations and a simple lexical decision experiment. Application of the diffusion model to a clinically relevant topic is demonstrated through an analysis of data from nonclinical participants with high- and low-trait anxiety in a recognition memory task. The model showed that after committing an error, participants with high-trait anxiety responded more cautiously by increasing their boundary separation, whereas participants with low-trait anxiety did not. The article concludes with suggestions for ways to improve and broaden the application of these models to studies of clinical disorders.     

Long-term Evaluation of Genetic Counseling Following False-Positive Newborn Screen for Cystic Fibrosis

This cross-sectional mixed method study was a long-term follow-up evaluation of families who participated in an earlier survey of their understanding of cystic fibrosis (CF) genetics and their infants’ false-positive CF newborn screening (NBS) results. Thirty-seven of the original 138 parents participated in the follow-up telephone survey. Results showed parents who received genetic counseling at the time of their infants’ diagnostic sweat tests had significantly higher long-term retention of genetic knowledge than those without genetic counseling. However, both groups still had misconceptions and lacked accurate information about the actual risk associated with being a CF carrier. Most parents either had already informed (65%) or planned to inform (19%) their children about the child’s carrier status. Mean child age at the time of disclosure was 9.2 years. Situational prompts were the most common reasons for informing their children. Neither parental knowledge, medical literacy, nor parental education predicted whether parents informed their children about their carrier status. False-positive NBS results for CF were not associated with parental perceptions of child vulnerability 11–14 years after the testing. Although the sample from this study was small, these findings underscore the benefits of genetic counseling at the time of the diagnostic sweat test and offer information that can assist parents in talking with their children about the implications of having one CFTR mutation.     

Surviving the Transformation: Social Quality in Central Asia and the Caucuses

This paper develops a sociologically informed understanding of what influences the lives and life-choices of people living in Kazakhstan and Kyrgyzstan (Central Asian Republics) and Armenia and Georgia (the Caucasus), four of the successor states of the Soviet Union that suffered significant social and economic changes following the collapse of the Union in 1991. The focus is on the nature of these societies for their citizens; ultimately we are concerned to understand what makes a society liveable for all, what type of society enables people to be generally satisfied with their lives. To do this we use the Social Quality model to derive indicators from which to model what makes for a liveable or at least tolerable society. The model is validated by reference to subjective satisfaction—how people feel about life in general—as the ultimate outcome indicator of individual well-being. The data we use were collected as part of a broader study of living conditions, lifestyles and health in eight of the successor states of the Soviet Union, the Confederation of Independent States (CIS).
