A neuroscience model of stuttering

Using motor control systems analysis and a reductionist approach, we provide a unified model of stuttering. This model views stuttering as a momentary instability in a complex multiloop control system. The model predicts the temporal conditions under which this instability will occur. Furthermore, these temporal conditions account for the efficacy of fluency-evoking maneuvers, therapy, and the variability of speech output in stutterers.     

The nature of prolonged word search

Two alternative hypotheses were considered concerning the process of prolonged search for an uncommon word in response to hearing its definition. One alternative is that a conscious retrieval effort brings the target progressively closer to threshold. The second is that the retrieval process is a random neural exploration outside of conscious control. A tachistoscopic probe was devised to compare word recognition thresholds after 10 sec versus 30 sec of presumed search time. Results failed to show a difference between the two delay conditions and were interpreted as inconsistent with the first alternative but consistent with the second.     

Introduction to Special Issue. Counselors Be Aware: Clients Come in Every Size,Shape, Color,and Sexual Orientation

In order to guarantee that each individual is free to pursue his/her potential, each member of AACD is charged to (a) engage in ongoing examination of his/her own attitudes, feelings, stereotypic views, perceptions and behaviors that might have prejudicial or limiting impact on women, ethnic, minorities, elderly persons, gay/lesbian persons and persons with handicapping conditions; (b) contribute to an increased sensitivity on the part of other individuals, groups or institutions to the barriers to opportunity imposed by discrimination; (c) advocate equal rights for all individuals through concerted personal, professional and political activity. (Position paper of the Human Rights Committee of the American Association for Counseling and Development, 1987, p.1)

Cross-sex comparisons: A word of caution

A cross-sex difference on one variable is often hypothesized to be related to a gender difference on a second variable. However, caution should be exercised in making such comparative hypotheses. We gathered the expected and actual examination grades for 168 female and 163 male college students. As in prior research, males had higher expectancies than females (p<.05). But analysis of the intrasex regression equations indicated that the relationship of expectancies to performance was different for women than it was for men. Thus, a cross-sex difference in expectancies did not correspond to a parallel difference in grades. This finding highlights the potential hazards of making certain cross-sex comparisons, and we argue for more caution in their application.     

Effects of gaze manipulation on subjective evaluation of neutral and phobia-relevant stimuli. A comment on Drake's (1987) 'Effects of Gaze Manipulation on Aesthetic Judgments: Hemisphere Priming of Affect'

Using neutral stimuli (mushrooms and flowers) and phobia-relevant stimuli (snakes and spiders), the present investigation examined the effect of gaze shifts on subjective evaluation of stimuli in female subjects (N = 29). One group of subjects had to orient to the right, whereas the other group had to orient to the left in order to see the stimuli. When left-handed subjects were excluded from the analysis, the results showed that subjects in the 'orient right' group gave a significantly more positive evaluation than subjects in the 'orient left' group. The results provide a replication of the phenomenon described by Drake (1987).     

Rats and bunnies: core kids in an American mall

Although adolescents use shopping malls as important places of congregation, very little attention has been paid to this phenomenon by social scientists. This paper reports on a qualitative, interview-based study of adolescents in a New England shopping mall. Regular, day-to-day frequenters (N = 23) were identified and interviewed extensively over a six-week period in 1988. These "core kids" exhibited a good deal of alienation from both family and school, and used the mall as a neutral ground on which to create a fragile but mutually supportive community of kind.
