Neural Systems Mediating American Sign Language: Effects of Sensory Experience and Age of Acquisition

ERPs were recorded from deaf and hearing native signers and from hearing subjects who acquired ASL late or not at all as they viewed ASL signs that formed sentences. The results were compared across these groups and with those from hearing subjects reading English sentences. The results suggest that there are constraints on the organization of the neural systems that mediate formal languages and that these are independent of the modality through which language is acquired. These include different specializations of anterior and posterior cortical regions in aspects of grammatical and semantic processing and a bias for the left hemisphere to mediate aspects of mnemonic functions in language. Additionally, the results suggest that the nature and timing of sensory and language experience significantly impact the development of the language systems of the brain. Effects of the early acquisition of ASL include an increased role for the right hemisphere and for parietal cortex and this occurs in both hearing and deaf native signers. An increased role of posterior temporal and occipital areas occurs in deaf native signers only and thus may be attributable to auditory deprivation.

Further evaluation of self and peer judgements of speech with delayed auditory feedback

Fifteen undergraduate students recorded a standard reading passage under simultaneous auditory feedback (SAF) and delayed auditory feedback (DAF, 210 ms). These pairs were rated for articulation and fluency differences, reading rate differences, pitch differences, loudness differences, and overall differences in quality of speech by the fifteen speakers and by ten peer judges. Results suggest that naive speakers under DAF form a self-impression of the effects of DAF upon their speech that is not different from the qualitative ratings of independent peer judges. The hypothesis that there was no overall difference between self and peer ratings was not rejected. Implications for the use of DAF as a research or treatment modality, or as both, are discussed.

Case vignette: to share or not to share

For years, the notion that researchers should share data freely with fellow scientists has been discussed widely. Some argue that this is especially true when the data are generated in federally funded projects. A recent provision in the reauthorization bill for the National Institutes of Health (NIH) would ensconce this principle in law. NIH grantees would be required, on demand, to furnish their data to other researchers. According to the proposed legislation, research data would have to be preserved and made avilable for 3 years after the completion of a project, and for 5 years following publication of the results in a scientific journal. One objective, according to a congressional aide, would be to make it easier for scientists with dissenting views to obtain and reanalyze data collected with public funds. It would also facilitate publication of alternative analyses. Personal records and patent applications would be exempted, but other data from clinical, behavioral, or epidemiological research focused on the evaluation or efficacy of a drug, medical device, or treatment of any sort would be covered immediately. Is such mandatory sharing of data ethical and appropriate scholarship? Does it raise potential for abuse? Should colleagues be required to provide such access to data, whether or not federal support was used in its collection?     

Interpersonal Assessment in Counseling and Psychotherapy

This article provides a review of some of the major instruments, methodologies, and strategies available to assess clients' interpersonal functioning. The focus is on instruments that provide characterizations of clients' and counselors' overt interpersonal behavior and covert reactions translated onto interpersonal circle models. A suggested interpersonal assessment battery is presented, and how the information obtained from this battery can be applied to assist in conceptualization and treatment efforts is described.     

Effects of counselor sex,student sex,and student attractiveness on counselors' judgments

Thirty-two male and thirty-two female high school counselors in a large metropolitan school district were provided with routine student profile data and asked to make predictions about the student's potential for post-high school education and to suggest occupations for the student to explore. All data reviewed by the counselors were identical except for a photograph of the student attached to the profile. Within counselor sex groups, counselors were randomly assigned to one of the following four photograph conditions: (a) attractive female; (b) unattractive female; (c) attractive male; and (d) unattractive male. Male subjects were found to discriminate on the basis of student sex when they suggested occupations for the student to explore. Predictions of post-high school education and the social status of suggested occupations were not found to be related to counselor sex, student sex, or student attractiveness.
