Assumed Similarity of Attitudes About AIDS Among Gay and Heterosexual Physicians

Heterosexual and gay physicians indicated their own attitudes on several issues related to the AIDS epidemic and attributed a position on each issue to the target group "most people." The heterosexual physicians' attitudes were more negative than the gay physicians' attitudes. Both groups judged that "most people" hold attitudes more negative than their own. The distance between own and attributed position as much greater for the gay individuals. This distance effect was due primarily to differences in self-ratings between the two groups. Own and attributed position correlated positively for each group of physiaans. Additionally, the tendency to assume similarity was marginally stronger for heterosexuals with high than low homophobia. Theoretical interpretation is presented.     

The effect of exploratory questions on solution quality

This experiment investigates whether the introduction of exploratory questions into a group problem-solving discussion influences the nature of the solution. Groups of three, including a discussion leader-member, were asked to develop at least three solutions toward improving output of a circular five-man assembly line. Many solutions are possible. One solution, rotation, is clearly superior to all others, yet is rarely developed. Leaders were given one of two different statements of the problem, a statement of two ways to improve a boring job, and three exploratory questions to read aloud to their groups prior to a 20-minute discussion. The job improvement questions were based on principles drived in Karsten's (1928) investigations into psychological satiation. Results indicate that exploratory questions cause groups to develop the insightful solution significantly more often than do comparable groups without experimental introduction of such questions. More generally, the results indicate that efforts directed toward upgrading the manner in which a task is experienced can generate inventive improvements in the group product.The author, a University of Michigan Ph.D. in psychology, taught in the psychology departments of North Carolina State University, the University of Maryland, as a visiting professor, at the University of Michigan; subsequently in the Schools of Management at the Universities of Rochester and Minnesota; extensively abroad, most recently in Japan.

The repetition effect in time judgments is not a function of the intensity of the stimulus defining the interval: implications for an arousal theory

College students (N = 17 per group) estimated the durations of time intervals ranging from 8 to 20 sec. Intervals were defined by tones of 35, 55, and 75 db for each of three groups. The estimates of all groups declined across trials, but the degree of decline did not differ as a function of stimulus intensity. These data call into question the view that the repetition effect is attributable to a decrement in general arousal.     

Effect of information feedback on temporal discrimination in concurrent and post-feedback measures

College students estimated time intervals (5, 6, 7, 8, and 9 sec.) where one group (N = 20) received information feedback in terms of actual interval durations and a second group (N = 18) received no information. Theshold measures were then taken for all subjects using the method of constant stimuli (comparison stimuli of 5, 6, 7, 8, and 9 sec. and a 7-sec. standard). In addition to increased accuracy and consistency of judgments, the feedback group showed a decreasing Weber fraction during the estimation phase, while the Weber fraction for the no-feedback group increased. The feedback group retained only a slight advantage in subsequent threshold measures; group differences in difference thresholds and derived nonparametric estimates of d' were nonsignificant.     

Some correlates of stuttering severity judgments

Thirteen adult male stutterers recorded the Amplifier Passage on high-quality audiotape. One sentence from each recording was paired with one sentence from each of the remaining 12 recordings. The resulting 78 sentence pairs were presented to eight speech-language pathologists who were asked to judge which stutterer in each pair was more severe and to rate the confidence of each of these judgements. The confidence ratings were analyzed by means of the individual differences model of multidimensional scaling. The results suggested that reading rate and the number of intrasentence pauses were important parameters in determining the severity of stuttering.     

Gender and sex-role appropriateness: Bias in the judgment of disturbed behavior

Male and female undergraduate raters made attributions of mental disorder, personality traits, and diagnostic and treatment judgments for four case studies in which sex of client and sex-role appropriateness of client behavior were manipulated. Significant interactions of sex-role appropriateness with both client sex and rater sex highlighted the significance of sex-role stereotypes in the attribution of mental disorder by nonprofessionals. The data indicated that these cultural sex-role definitions had the strongest negative effect for females and the female sex role. Implications of these findings for the clinical judgment process and female self-perception are discussed.The order of authorship was determined by random selection.     

Modality-specific interference with verbal and nonverbal stimulus information

Subjects recalled both letters and the locations of letters in 2 by 3 and 1 by 6 matrices after either no interfering activity or visual, auditory, or kinesthetic interfering activity. Results for each type of matrix indicated the presence of selective auditory (verbal) interference with the recall of letter identity and selective visual and kinesthetic interference with the recall of letter location. Supplementary correlational analyses indicated that the presence of such a dual encoding strategy was most consistent across subjects for the 2 by 3 matrix. Although the results indicated that use of different modes of representation was related to the verbal-nonverbal nature of the information, it was shown that the structure of the stimulus array also affected the nature of the representation.     

Schedule-induced drinking as functions of interpellet interval and draught size in the Java macaque

Three Java monkeys received food pellets that were assigned by both ascending and descending series of fixed-time schedules whose values varied between 8 and 256 seconds. The draught size dispensed by a concurrently available water-delivery tube was systematically varied between 1.0 and 0.3 milliliter per lick at various fixed-time values during the second and third series determinations. Session water intake was bitonically related to the interpellet interval and was determined by the interaction of (1) the probability of initiating a drinking bout, which fell off at the highest interpellet intervals and, (2) the size of the bout, which increased directly with increases in interpellet interval. Variations in draught size had little effect on total session intakes, but reduced bout size at draught sizes of 0.5 milliliter and below. Thus, a volume-regulation process of schedule-induced drinking operated generally at the session-intake level, but was limited to higher draught sizes at the bout level.
