Sex differences in performance and hemispheric organization for a nonverbal auditory task.

Musically experienced and inexperienced men and women discriminated among fundamental-frequency contours presented either binaurally (i.e., same contour to both ears) or dichotically (i.e., different contours to each ear). On two separate occasions, males made significantly fewer errors than did females in the binaural condition, but not in the dichotic condition. Subjects with prior musical experience were superior to musically naive subjects in both conditions. The dichotic pitch task produced a left-ear advantage, which was unrelated to gender or musical experience. The results suggest that the male advantage on the binaural task reflects a sex difference in the coordination of the two hemispheres during conjoint processing of the same stimuli rather than a difference in the direction or degree of hemispheric specialization for these stimuli.     

THE INTERNATIONAL ASSIGNEE: THE RELATIVE IMPORTANCE OF FACTORS PERCEIVED TO CONTRIBUTE TO SUCCESS

The present study sought to empirically identify what factors are important for international assignee perceived success along with their relative importance. Subjects were 338 international assignees from diverse countries (nationality) and organizations, assigned to diverse countries, and performing diverse jobs. Five factors were identified and in a descending order of importance, these were Family Situation, Flexibility/Adaptability, Job Knowledge and Motivation, Relational Skills, and Extra-Cultural Openness. Although importance ratings were not influenced by job type (managerial/nonmanagerial status), they were influenced by organizational type. In general, the pattern of importance ratings for service organization international assignees was different from those of international assignees from other organizational types. Furthermore, service organization international assignees ascribed more importance to relational and psycho-social factors. The perceived relative importance of psycho-social factors reported by the study's participants tends to suggest that more attention should be paid to these factors in the selection and training of international assignees.     

EXPERIENCED HIRING VERSUS COLLEGE RECRUITING: PRACTICES AND EMERGING TRENDS

Although much professional and managerial hiring involves experienced workers, previous recruitment research has focused almost exclusively on new college graduates. To remedy this imbalance, 251 staffing professionals were surveyed concerning experienced-versus-college hiring practices in their organizations. Results suggest that a majority of positions requiring a college degree are filled with experienced workers. Experienced hires are evaluated more highly than new graduates on most characteristics (understanding business, knowledge of competition, realistic expectations, technical skills, interpersonal skills, writing skills, work ethic, likelihood of success, personal ethics), although new graduates are evaluated more highly on open-mindedness and willingness and ability to learn new things. Higher proportions of experienced hiring are associated with organizational growth, short-term staffing strategies, older workforces, and less dynamic business environments. Perceived success of experienced hiring is associated with greater use of effective recruitment sources, older workforces, and more competitive salary offers.     

The foreperiod effect revisited

This paper explores four factors which could be important in accounting for the discrepant results which have previously been obtained with respect to the effect of foreperiod duration on reaction time (RT). In some studies a clear effect of foreperiod duration on auditory RT has been found, in contrast to a recent finding that foreperiod duration affected visual RT but not auditory RT. By means of two experiments, the effects of practice, time-on-task, reaction task (a-reaction versus selective reaction) and signal intensity were studied. The latter variable appears to be the principal determinant of the discrepant results in that there is an interaction between signal intensity, foreperiod duration and modality. The results fit the hypothesis that signals beyond a given intensity exert an immediate arousing effect which counteracts the foreperiod effect.     

Inferences about the femininity of competent women and their implications for likability

Male (N=59) and female (N=60) college students were given a written protocol describing a competent, achievement-oriented female stimulus person (SP) with either a masculine or feminine pattern of vocational and avocational interests. Three groups were given a masculine-pattern protocol and one group was given a feminine-pattern one. They were then asked to rate the SP on likability in work and social settings, femininity, and a number of other personal attributes. Two groups given the masculine-pattern protocol were also supplied with the SP's responses to items from a “personality” test answered in a predominantly feminine (Masculine—Feminine SP) or masculine (Masculine-Masculine SP) direction. The remaining groups (Masculine-Neutral and Feminine-Neutral SPs) were given no additional information. In agreement with previous findings, the Masculine-Neutral SP was liked more in social settings than was the Feminine-Neutral one. It was hypothesized and confirmed that the Masculine-Neutral SP would be perceived as similar to the Masculine-Feminine SP in femininity and likability and that both these SPs would be judged to be higher on these characteristics than the Masculine-Masculine. Complex results were obtained from the ratings of other attributes. Overall, they indicated that the Masculine-Feminine SP, in whom femininity was explicitly suggested, received the weakest ratings on a series of achievement-related attributes and the Masculine-Neutral SP the strongest.     

Sensitivity to low doses of ethanol and pentobarbital in mice selected for sensitivity to hypnotic doses of ethanol.

These experiments assessed sensitivity to low doses of ethanol and pentobarbital in mice that had been selectively bred with respect to ethanol sleep time (the length of time an animal remains on its back following a hypnotic dose of ethanol). The hypothesis under investigation was that short-sleep (SS) mice might be more sensitive than long-sleep (LS) mice to excitatory effects produced by low doses of depressants. In support of this hypothesis SS mice were more active in an open-field test after ethanol than were LS mice. The lines did not differ in performance on a rotating-rod apparatus after these same doses of ethanol, suggesting that the difference in open-field activity was not attributable to a greater impairment of locomotor activity in LS mice. A similar difference in the open-field activity of the selected lines was observed with pentobarbital.     

Differentiation of adolescent activity participation

The sex typing or lack of it among 133 adolescent activities was investigated. Twenty-seven percent (32) of the activities on an Adolescent Activity Questionnaire showed very clear participation differences for male and female adolescents (11 to 18 years old). The initial two factors extracted in a principal components factor analysis were easily interpreted as feminine and masculine activities. Discriminant function analysis of 15 items from the first three factors yielded an 8-item function on the basis of which every sample member was correctly classified as male or female. Masculine activities included more sports-related activities and activities dealing with mechanics and building, whereas feminine activities were domestic in nature and included more sedentary activities (e.g., reading, writing in diaries).     

Sentence comprehension following agenesis of the corpus callosum

The sentence comprehension skills of a 6-year-old girl with callosal agenesis were compared to skills of three other children matched for age and verbal IQ. Sentence-picture matching and acting out tasks were used with reversible active, passive, and center-embedded relative clause sentences. The acallosal subject showed a deficit in syntactic comprehension. The difficulty was due to a failure to assign correct semantic roles to some sentence forms, not to a lack of ability to discriminate among the sentence forms. The data are consistent with a previous report by M. Dennis (1977, In Topics in child neurology, pp. 189-212) that in acallosal subjects syntactic comprehension can be adversely affected. Because this acallosal subject is only 6 years old, follow-up studies will be needed to determine whether she eventually acquires normal syntactic skills.
