A prognostic utility bias in judgments of similarity between past and present instances: How available information is deemed useful for prediction

A variety of theorists have proposed that individuals desire to be confident in their inferences and predictions. One way this can be accomplished is by overestimating the extent to which available information provides a logic basis for such conclusions. Thus, when one's goal is to make an accurate prediction, if information about a prior known instance has potential implications for the prediction, one may overestimate the similarity of the prior known instance to the current instance. In this way, the perceived utility of the information as a basis for prediction can be inflated. To test this idea, three studies were conducted. In each study, subjects were asked to judge the similarity of past instances to an upcoming instance for which an outcome prediction was required. Judging a past instance as similar to the upcoming instance should only provide a firm basis for outcome prediction if outcome information regarding the past instance is known. Therefore, it was expected that when subjects are asked to make an outcome prediction, they would judge a past instance more similar to the upcoming instance if outcome information about the past instance is known than if it is not. Support for this hypothesis was obtained along with evidence concerning the conditions under which the eflect does and does not occur.     

Endorsements by Mexican-Americans of the Bem Sex-Role Inventory: cross-ethnic comparison

Gender-related personality traits among Mexican-American men and women were examined. The sample consisted of 307 Mexican-Americans (150 women, 157 men) in a predominantly Mexican and Mexican-American community in South Texas. Mexican-American men scored significantly higher than the women on eight masculine items, whereas Mexican-American women scored higher than the men on four feminine items. A comparison between the scores of Mexican-Americans on the Bem Sex-Role Inventory with those of the original sample in the inventory's manual showed that the scores for the Masculinity and Femininity subscales for both Mexican-American men and women were not significantly different from those of the original sample. A significant difference, however, was found on some of the items of the inventory. Analysis also indicated that more Mexican-American men were categorized as Feminine and Androgynous than were non-Hispanic Euro-American males in the original sample. Among Mexican-American women there were more individuals classified as Masculine and Undifferentiated and a lower percentage as Feminine than among the original sample. Implications and recommendations based on the results are discussed.     

Research in Counseling

This column is based on the belief that research can provide meaningful data to the practicing counselor. While individual studies may not provide sufficient data on which to act, a combination of separate research efforts or a large-scale, long-term research project does have the possibility of providing sufficient data. This column will undertake to provide that data by either reviewing the current research in a specific area or examining the results from a long-term project. The emphasis will be on implications for the counselor, so there will be little if any information on research design or statistical procedures. Readers desiring more detail about a particular study should write directly to the original author(s). Readers who desire to have the results of their research and/or innovative approaches considered for review in this column should send the material to Richard W. Warner, Jr., Counselor Education, 2054 Haley Center, Auburn University, Auburn, Alabama 36830.     

A computer-controlled language training system for investigating the language skills of young apes

A computer-controlled language training system was designed and constructed to enhance the objectivity and efficiency of inquiry into the language-relevant behaviors of apes. The system allows the S to gain control over the events of the 24-h day in direct correspondence with its competence in using a keyboard on which each key represents a word. Various incentives can be obtained through the selection and depression of appropriate keys in accordance with rules of sentence structure monitored by a computer. The system is flexible and allows for eventual conversation between man and ape, with the computer as the intermediary. A Teletype records all that transpires. Achievements of the chimpanzee S over the course of the first 8 months of the system’s operation attest to the worth of the system and training methods.     

Reducing stress by counterattitudinal advocacy

In one condition, subjects were made apprehensive by being threatened with shock and then were induced to publicly argue that they were not apprehensive about the situation. It was hypothesized that the subjects who were induced to advocate a position contrary to their feelings about the situation would experience dissonance. To reduce dissonance, these subjects were expected to redefine the situation as less threatening and thereby experience less apprehension regarding the situation than subjects in a control threat condition. Results of physiological measures and a postexperimental questionnaire supported the expectations. Implications of the study for psychotherapy were mentioned.     

Women Behaving Badly: Gender and Aggression in a Military Town, 1653–1781

Magistrates records from the English town of Portsmouth show the towns women to have been exceptionally violent. Women accounted, on average, for just over 31% of all assaults on record for the years 1653 to 1781. We used a combination of quantitative and qualitative methods to compare the fighting styles of men and women and to examine the extent to which these were gendered. Particular attention was paid to levels of violence between pairs of brawlers. The most common form of violence was male-on-male (2,666 cases), followed by female-on-female (1,690), male-on-female (1,675), and female-on-male (299). Of these pairings, female-on-male assaults were the most violent, as measured by the types of weapons used by the aggressors, and female-on-female pairings were the least violent.Funding was provided by grant 410-2000-0467 from the Social Sciences and Humanities Research Council of Canada. The authors are profoundly grateful to the gracious and highly capable staff of Portsmouths Museums and Records Service, including, most notably, Michael Gunton, Diana Gregg, Donna Malcolmson, and Sarah Speller. Special thanks also go to the team of volunteers who transcribed the towns sessions papers, thus greatly facilitating our entry of the same into a database. They were, in alphabetical order, Kate Beatty, Barbara Gower, Ursula Heinrich, Pam Honeysett, George Hothersall, Marjorie Hothersall, Una Lowe, Betty Richardson, Marjorie Ripper, and Brenda Whorton. There was one other volunteer: an inmate at the Kingston Prison just outside Portsmouth. Back in Toronto, several more people assisted in entering the records into a database. They were, in alphabetical order, Joanne Cordingley, James Hewitson, Allyson Lunny, Yvonne Pelletier, and Victoria Vaag.
