Face recognition by hand

We investigated participants' ability to identify and represent faces by hand. In Experiment 1, participants proved surprisingly capable of identifying unfamiliar live human faces using only their sense of touch. To evaluate the contribution of geometric and material information more directly, we biased participants toward encoding faces more in terms of geometric than material properties, by varying the exploration condition. When participants explored the faces both visually and tactually, identification accuracy did not improve relative to touch alone. When participants explored masks of the faces, thereby eliminating material cues, matching accuracy declined substantially relative to tactual identification of live faces. In Experiment 2, we explored intersensory transfer of face information between vision and touch. The findings are discussed in terms of their relevance to haptic object processing and to the face-processing literature in general.     

Auditory temporal processing deficits in children with periventricular brain injury

The present study investigated whether auditory temporal processing deficits are related to the presence and/or the severity of periventricular brain injury and the reading difficulties experienced by extremely low birthweight (ELBW: birthweight <1000 g) children. Results indicate that ELBW children with mild or severe brain lesions obtained significantly lower scores on a test requiring auditory temporal order judgments than ELBW children without periventricular brain injury or children who were full-term. Structural equation modeling indicated that a model in which auditory temporal processing deficits predicted speech sound discrimination and phonological processing ability provided a better fit for the data than did a second model, which hypothesized that auditory temporal processing deficits are associated with poor reading abilities through a working memory deficit. These findings suggest that an impairment in auditory temporal processing may contribute to the reading difficulties experienced by ELBW children.     

Pharmacogenetics: ethical issues and policy options

Pharmacogenetics offers the prospect of an era of safer and more effective drugs, as well as more individualized use of drug therapies. Before the benefits of pharmacogenetics can be realized, the ethical issues that arise in research and clinical application of pharmacogenetic technologies must be addressed. The ethical issues raised by pharmacogenetics can be addressed under six headings: (1) regulatory oversight, (2) confidentiality and privacy, (3) informed consent, (4) availability of drugs, (5) access, and (6) clinicians' changing responsibilities in the era of pharmacogenetic medicine. We analyze each of these categories of ethical issues and provide policy approaches for addressing them.     

Review of quantity and types of spirituality research in three health care databases (1962-1999): implications for the health care ministry

Using computer technology to identify the term "spiritual," these researchers present results of the 2306 citations and compare five criteria discovered with research reported in four pastoral counseling journals. The authors note the limitations of such a search and the possible implications of the findings for health care ministry.     

Sex offender community notification: managing high risk criminals or exacting further vengeance?

The current trend in dealing with convicted sex offenders is to impose long prison sentences followed by stringent release conditions. Added to this practice has been the policy of making such offenders who have been returned to society more visible to the public. In state after state, sex offender community notification laws have been passed, enabling communities to be put on notice that a convicted sex offender has become a resident. To date there has been little empirical evidence regarding the impact of these laws on managing sex offenders in the community. This study focuses on the social and psychological effects of community notification on sex offender reintegration within those communities where notification has occurred. Data are derived from face-to-face interviews with 30 convicted sex offenders, residing in various locations throughout Wisconsin, who were the subjects of community notification. The findings indicate that community notification can have a critical impact on the minimum essentials needed for the reintegration of offenders within the community. What is proposed is a reintegrative approach which suggests that stable housing and employment would mitigate the disruptive and antitherapeutic effects of community notification.     

Sex offender community notification: examining the importance of neighborhood meetings

Within the last decade, federal and state laws have been passed authorizing or requiring the notification of local residents that a convicted sex offender will be released and living in their neighborhood. The community meeting method of notifying neighborhood residents, although the subject of extensive news media attention, has been largely overlooked by empirical researchers. This study focuses on the experience of residents who attend such meetings and how that experience factors into a collective response on the part of the community. Data are derived from attendee surveys and recorded observations taken at all community notification meetings held throughout Wisconsin during a nine month period. The findings suggest that community notification meetings, if properly conducted, can perform an important role in managing the behavior of known sex offenders in the community. However the decision to notify and involve the public in an informal network of neighborhood surveillance may come at the cost of increased community anxiety. This anxiety is related to how the attendees were notified of the meeting, how clearly the purpose of the meeting was conveyed, and how organized the meeting appeared to the audience. Suggestions on how to more effectively utilize the community meeting method of notification are presented.     

How bad is a 10% chance of losing a toe? Judgments of probabilistic conditions by doctors and laypeople

We presented a Web questionnaire to 139 physicians and medical researchers and 109 laypeople. The subjects made judgments of badness and importance of prevention for eight medical conditions at each of seven different probability levels. By assuming that the response to each of the 56 risks was monotonically related to transformations of the probability and of the disutility of the condition, we could assess the relative effect of probability and disutility on each subject's judgments. Physicians' judgments were more sensitive than laypeople's judgments to changes in probability. Older and female laypeople were less sensitive to probability (and correspondingly, more responsive to differences in severity among medical conditions). Laypeople varied more than physicians in their responsiveness to probability. These results point to general individual differences in the effect of probability on evaluations of medical risks. They may also provide insight into causes and noncauses of physician-patient miscommunication.     

Competition between endogenous and exogenous orienting of visual attention

The relation between reflexive and voluntary orienting of visual attention was investigated with 4 experiments: a simple detection task, a localization task, a saccade toward the target task, and a target identification task in which discrimination difficulty was manipulated. Endogenous and exogenous orienting cues were presented in each trial and their validity was manipulated orthogonally to examine whether attention mechanisms are mediated by separate systems and whether they have additive and independent effects on visual detection and discrimination. The results showed that each orienting mechanism developed its typical and independent effect in every case except for the difficult identification task. A theoretical framework for understanding the relationship between endogenous and exogenous orienting of attention is proposed, tested, and confirmed.
