Duration of subsegments within the intervocalic interval in stutterers and nonstutterers

Intervocalic intervals (IVI) from the contextual fluent speech of 14 stutterers and controls were examined at one-quarter speed on simultaneously prepared spectrograms and intensity x time displays. Seven subsegments within the IVI were identified and their durations compared between the two groups. Stutterers were slower than controls in transitional subsegments, corresponding to movements of the tongue and larynx, but not in steady-state subsegments. The results are interpreted as suggesting that stutterers are not able to move their laryngeal and supralaryngeal structures as quickly as nonstutterers.     

Participation in competitive amateur sports as a function of psychological androgyny

Previous research has indicated that women who participate in competitive sports tend to score low on traditional measures of femininity, and such women have been characterized as masculine (Harris, 1975). These studies used the Bem Sex Role Inventory (BSRI; Bem, 1974) to measure the degree of sex-typing in 25 male and 23 female competitors in a national racquetball tournament and 24 male and 27 female competitors in local badminton, squash, and handball tournaments. Results for the first study indicated that a larger percentage of androgynous women as compared to traditionally feminine or masculine women entered the racquetball tournament, whereas the largest percentage of male entrants were in the masculine role category. Results for the second study indicated that among contestants who cited a competitive reason for entering the tournament, a larger percentage of both men and women were sex-typed as androgynous or masculine rather than feminine. These results were subsequently reanalyzed according to an alternate procedure suggested by Bem (1977) in order to compare the behavior of subjects who score high on both masculinity and femininity and those who scored low on both. While the percentages of masculine, feminine, and androgynous subjects were changed by the new categorization procedure, there were no differences found between high—high and low—low scorers. Implications of these results for the traditional characterization of women participants in competitive sports and for the usefulness of the BSRI in predicting nonlaboratory behavior are discussed.Portions of this article are based on an honors thesis submitted by the senior author to the University of Winnipeg.

Toward an objective evaluation procedure of the Kinetic Family Drawings (KFD).

The feasibility of employing a quantitative scoring procedure for evaluating the Kinetic Family Drawings (KFD) was examined. A quantitative scoring procedure was developed from the clinical hypotheses Burns and Kaufman (1970, 1972) to score 21 measurable KFD styles, actions, and characteristics. The scoring procedure was employed to evaluate 116 KFDs obtained from four groups of boys to determine the effectiveness of the procedure to differentiate among two levels of emotional adjustment and the two levels of age. The results indicated that four of seven sets of extracted component scores significantly differed between the emotionally well-adjusted and the emotionally disturbed groups. One set of component scores significantly differed between the younger and the older groups, while two sets of component scores did not differ among any of the four groups. The KFD total score was found to differ significantly only between the young emotionally disturbed and the young emotionally well-adjusted groups. It was concluded that a quantitative scoring procedure for the KFD is feasible.     

Polarizing effects of social comparison

Does exposure to others' judgments merely elicit conformity to what is observed? Two experiments are reported in which people who were merely exposed to others' responses tended not to conform to the average observed response but to exceed it in the socially preferred direction. These experiments complement social psychology's historic emphasis on conformity by suggesting that not only do people avoid being markedly deviant from others; they also act to differentiate themselves from others toward the extreme that reflects the group ideal.     

Conditioned fear extinction and reinstatement in a human fear-potentiated startle paradigm

The purpose of this study was to analyze fear extinction and reinstatement in humans using fear-potentiated startle. Participants were fear conditioned using a simple discrimination procedure with colored lights as the conditioned stimuli (CSs) and an airblast to the throat as the unconditioned stimulus (US). Participants were extinguished 24 h after fear conditioning. Upon presentation of unsignaled USs after extinction, participants displayed significant fear reinstatement. In summary, these procedures produced robust fear-potentiated startle, significant CS+/CS- discrimination, within-session extinction, and significant reinstatement. This is the first demonstration of fear extinction and reinstatement in humans using startle measures.     

A study of grouphate in a course on small group communication

This study explored the relationship between grouphate and cohesion, consensus, relational satisfaction, affective learning, and cognitive learning. Participants were 83 undergraduate students enrolled in an introductory course on small group communication. Participants completed the Grouphate scale, the Classroom Cohesion scale, the Consensus scale, the Relational Satisfaction scale, three subscales of the Instructional Affect Assessment Instrument, and the Cognitive Learning Loss measure. Mean grouphate significantly increased during the semester, and negative correlations were found between scores for grouphate and cohesion (-.50), consensus (-.45), relational satisfaction (-.58), attitude toward the behaviors recommended in the course (-.23), the likelihood of developing an appreciation for the course content (-.33), and cognitive learning (-.32). Results may imply that students' grouphate is not associated with prosocial outcomes of the group work in this course.     

Short-term recognition memory of tones

Four Os participated in a recognition memory experiment for a period of 5 weeks. The task required O to judge whether two temporally sequenced tones (ISI = 0.5, 2.0, or 8.0 sec) were the “same” or “different ” Latencies and confidence ratings were obtained for each judgment. TSD analyses applied to individual O’s data indicated consistent and rapidly decreasing d’s as a function of ISI. ROC functions generated from the latencies and ratings produced comparable results, indicating the feasibility of using latency measures along with the type of judgments made to obtain sensitivity measures. Response bias, as indicated by the differences in the latencies between “same” and “different” judgments, did not produce consistent trends.
