The influence of perceptual and motor factors on bimanual coordination in a polyrhythmic tapping task

Summary In this study the role of perceptual and motor factors on the motor organization (integrated versus parallel) adopted by musically skilled and unskilled subjects in a polyrhythmic tapping task was investigated. Subjects tapped a 3:2 polyrhythm to match the timing of two isochronous tone trains, one tone train for each hand. Perceptual factors were examined by the manipulation of the frequency difference between the tone trains to produce either an integrated or a streamed percept. Motor factors were examined by comparison of performance on two versions of the 3:2 polyrhythm. In one (simultaneous) version, each cycle of the polyrhythm began with a simultaneous left- and right-hand tap. In the other (shifted) version a 100-ms interval was introduced between the initial left and right taps in each cycle. Examination of the pattern of variances and covariances among intertap intervals suggested that most of the subjects in this study adopted an integrated motor organization that involved interleaving the timing of the two hands. Further analysis revealed that a serial chained model described the pattern of covariances best for the simultaneous pattern, whereas a hierarchical organization described the pattern of covariances for the shifted pattern best. The finding that performance was more accurate with integrated tones than with streamed tones provides some support for a perceptual-motor facilitation hypothesis.     

Gender role socialization in toy play situations: Mothers and fathers with their sons and daughters

This study examined the interaction within and between 20 intact families. As in past research, when parents were separated and not influenced by their child (i.e., completing a toy desirability scale), traditional findings were supported; neutral toys are not specific to the gender of the child while feminine toys were preferred for girls and masculine toys were preferred for boys. However, when parents were actively engaged in play with their child this traditional pattern was not supported. In general, parents spent the least amount of time with feminine toys. Children eagerly accepted most of the toys presented by their parents and their enthusiasm was equal for the toys in all three categories. This research suggests a change in parents' perceptions of what is acceptable gender-typing behavior.     

The Role of Emotion in the Construction of Career in Parent—Adolescent Conversations

The role of emotion in the construction of career has not always been clear despite its importance in people's lives and in counseling. Recent conceptualizations suggest that emotion is a complex relational process that is socially constructed. This study illustrates the role of emotion in the construction of career from an action theory perspective. Two parent—adolescent conversations about career from a group of 14 conversations are analysed in detail to demonstrate the ways in which emotions serve to energise action and career and lend context and meaning to the process of constructing career in the family setting.     

A reexamination of sex differences in job preferences

Previous research has found conflicting answers to the question of whether males and females share similar preferences for various job characteristics. It is difficult to determine if the different findings are due to the different populations sampled, the various methodologies employed, or to a real change in the phenomenon itself. This study essentially replicates earlier work by having 130 male and 84 female college students rate the importance of 10 job characteristics for both themselves and members of the opposite sex. Both sexes rated motivators as important, but females also placed importance on the hygienes. Males tended to underestimate the importance of the motivators for females, while females overestimated the importance of hygienes for males. The subject's sex could be predicted by both the importance for self and importance for opposite sex ratings, contrary to the earlier study. The difference in results and interpretation was shown to be due to the type of analyses used. Additionally, it was found that females' job preferences were related to their mothers' educational achievement.     

An exploration of leadership in a medical mutual help organization

Studied 45 current leaders of local chapters of a medical mutual help organization. Cluster analysis of variables depicting routes to leadership produced six clusters: Health Professionals with a Mission, Connected Health Professionals, Career Leaders, Grass-roots Founders, Connected Grass-roots Leaders, and Obligated Veterans. These clusters differed on criterion measures of burnout, hardiness, and perceived obligation to continue as a leader, e.g., Connected Health Professionals and Career Leaders were less burned out, more hardy, and perceived less of an obligation to continue in the leadership role than Health Professionals with a Mission. In terms of leadership activities, Help Provision and Advocacy constituted less than one fifth of all activities but were rated as most rewarding. In contrast, the activities that made up the bulk of leaders' work--building membership, system maintenance, and organizational growth--were not rated as particularly rewarding. Results are discussed in the context of research directions and practice.     

The job climate for women in traditionally male blue-collar occupations

Rapid growth has been observed in recent years in the number of women entering traditionally male blue-collar occupations, yet researchers have paid little attention to this pioneering group. The present study undertook a comparison of the job conditions of two groups of nontraditional women workers, tradeswomen (N=71), and transit workers (N=151); a third group, school secretaries (N=389), was studied as a comparison group of traditionally female workers. Results from a 16-page mail questionnaire revealed that women in traditionally male occupations encountered significantly more adverse working conditions than did their traditional counterparts, and, in addition, reported significantly less satisfaction and more stress at work. Tradeswomen were the most likely to experience sexual harassment and sex discrimination, and black tradeswomen to experience race discrimination. The degree of job satisfaction expressed by the secretaries was unexpected, since most evidence suggests that clerical workers lack autonomy, and encounter boredom and routinization on the job. These findings are discussed in terms of gender segregation and the need to focus future research efforts on specific occupational groups in order to make appropriate policy recommendations as well as to provide help for women in these jobs.This research was supported by grants from the National Institute for Occupational Safety and Health (Grant No. 1 RO1 OH02162-01A1) and the College of Health and Human Development, The Pennsylvania State University.

Washing, drying, and anointing in adult humans (Homo sapiens): commonalities with grooming sequences in rodents.

Very few behavioral patterns generalize across human and nonhuman species. We describe washing, drying, and anointing sequences in humans (Homo sapiens) that may have analogies with other species. The rank ordering of washing, drying, and anointing body parts was obtained over 3 successive days for 37 men and 60 women. Variation in rank ordering of body parts was nonrandom, and a cephalocaudal progression was evident for each behavior. Reliability of the behaviors as well as the correlations across rankings were highly significant, which indicates a generalized cephalocaudal progression for all 3 behaviors. Women's anointing was most variable, which suggests a more specific function. The cephalocaudal action pattern described for humans is similar to that for Mongolian gerbils and laboratory rats. Cross-species functions, such as these, may add to our understanding of common developmental and learning processes.     

Psychometric properties of attitudinal measures of behavioral treatment in geriatric settings

Internal consistency of two forms of the Geriatric Treatment Acceptability Survey (GTAS) and the Attitudes toward Behavior Analysis Scale (ABAS), a global measure of attitudes toward behavior modification, was evaluated. Alpha coefficients regarding treatment acceptability ratings for GTAS Form H were: (a) wandering 0.94; (b) hoarding 0.96; (c) disruptive behavior 0.92; (d) property destruction 0.95; and (e) aggression 0.94. Internal consistency for Form NH was: (a) wandering 0.96; (b) hoarding 0.97; (c) disruptive behavior 0.96; (d) property destruction 0.97; and (e) aggression 0.76. Internal consistency of the ABAS resulted in alpha coefficients of 0.90 (total score); 0.87 (ethics and humaneness); and 0.76 (use). These measures appear useful in assessing older adults, nursing home patients' and geriatric nursing staffs' global and specific attitudes regarding the use of behavioral treatments with older adults. Further research is needed to establish psychometric constructs assessed by the instruments and sensitivity to detecting change in attitudes based on educational or clinical interventions.
