Asymmetry of perception in free viewing of chimeric faces

We have devised a new free-vision task to index functional cerebral asymmetry for processing facial characteristics. Confirming its sensitivity to properties of lateralized hemispheric functions, left- and right-handers were clearly differentiated on this task with respect to several aspects of performance that conform with known differences between handedness groups in hemispheric asymmetry. Additionally, there were highly reliable and stable individual differences in perceptual asymmetries within handedness. Analyses of items in the task revealed that most of the differences between items in the asymmetries they elicited were random.     

Facing up to the issues: Reply to Hellige (1983)

In a recent article in this journal, Hellige (Brain and Cognition, 2, 199-203, 1983) presented a critique of the chimeric-face technique that was used by us to validate a hand preference questionnaire. Data were presented by Hellige to show that the left visual field (LVF) bias that occurs on this task is due primarily to differences in detail in the features of the two faces and not because of right hemisphere dominance for face perception. In our rebuttal, we acknowledge that the two faces are not mirror-image duplicates of each other, but contend that this fact does not explain why differences between left-handers and right-handers have been observed on this task. Further data on the role of handedness as well as other variables impacting on this task are presented. A possible explanation is also offered for the rather small extent of LVF bias that Hellige obtained when he used corrected (i.e., true mirror-image) versions of Jaynes' chimeric faces.     

Generalized and lateralized effects of concurrent verbal rehearsal upon performance of sequential movements of the fingers by the left and right hands.

College student subjects performed a sequential typing task requiring bilaterally synchronized movements (Experiment 1) or unilaterally synchronized movements (Experiment 2) singly, and concurrently with silent and vocal rehearsal of verbal lists varying in redundancy. Rehearsal interfered with bilaterally synchronized movements more when the right hand was leading the sequence than when the left hand led, and with movements of the right more than the left hand in unilaterally synchronized movements. Results are interpreted in terms of intrahemispheric and general capacity competition between the concurrent performances.     

Achievement and affiliation motivation in career-oriented and homemaking-oriented college women

The purpose of this research was to investigate the possibility of an interaction between need for achievement and need for affiliation in career-oriented and homemaking-oriented college women. In the first study, scores on the appropriate scales (Achievement and Affiliation) of the Adjective Check List were obtained for 250 female college students, who were also classified as career or homemaking oriented on the basis of their responses to a questionnaire concerning postcollege plans. No significant differences were found between the career- and homemaking-oriented groups on Achievement and Affiliation; but, as predicted, a significant interaction occurred between the two variables. A second study, involving 257 college women and employing the same procedures and analysis, replicated the results of the original study: no main effects, but a significant interaction between Achievement and Affiliation. Implications of the findings for female career development and the counseling of women are discussed.     

Job satisfaction among students in work education programs

Data were collected from 1016 students in grades 9–14 from 50 work education programs. Data were also collected from 696 similar students who held part-time jobs but were not participating in work education programs. Participating students were significantly more satisfied with their jobs than were the nonparticipating students. Group atmosphere, availability of adult role models, meaningfulness of work roles, and availability of feedback accounted for much of the variation in job satisfaction among students.     

The effect of verbal reinforcement on career choice realism

Twenty-four male undergraduates viewed 102 slides containing occupational titles and stated whether or not each represented a realistic career choice. Each subject was given three trials, with the experimental subjects receiving positive verbal reinforcement on the second trial for realistic responses. (If the choice was congruous with the individual's occupational type, as determined by the Vocational Preference Inventory, it was scored as realistic.) The results of the research revealed a tendency for all subjects to increase in career choice realism as a function of participation in the experiment, with significantly (p < .05) more experimental subjects than control subjects demonstrating an operant pattern of responses. Implications of the findings for counselors were discussed.     

On signalling that it's your turn to speak

The operation of a “speaker-state signal” in two-person, face-to-face conversations is hypothesized. Display of this signal by an auditor appears to indicate, among other things, that he is claiming the speaking turn, differentiating this action from a “back-channel behavior” by which he merely acknowledges some portion of the speaker's message. The signal also appears to play a part in the resolution of situations in which both participants simultaneously claim the speaking turn. The signal is defined as the display of at least one of a set of four behavioral cues, two in paralanguage and two in body motion.     

Threats and promises: Reputational consequences and transfer of credibility

This study was designed to investigate the reputational consequences of making threats and promises and how they affect subsequent credibility. Eighty-eight high school girls were given predetermined information about the past behavior of their pairmates prior to receiving influence attempts from them. Each first learned that her pairmate had (1) threatened or promised in the past and then learned whether she had (2) fulfilled or failed to fulfill her threat or promise. The subject herself then received a threat or promise from her pairmate. As anticipated, threateners were viewed less favorably than promisers. These impressions were maintained when it was learned that commitments had been fulfilled, but altered decidedly when it was learned that they had not. Credibility or lack of it was found to generalize from threats to promises and from promises to threats only under some conditions. It was concluded that the fit between existing impressions and proclaimed future activity, not a person's record for past reliability, is often the critical determinant of whether or not she is judged to be credible.     

The accuracy of self-administration and scoring on Holland's Self-Directed Search

This study assesed the extent to which Ss commit various types of errors when completing Holland's Self-Directed Search (SDS) entirely on their own. Nearly all Ss made some type of error and approximately half of the Ss made errors which affected their final three-letter summary codes. Almost one-fifth of the Ss made errors resulting in an incorrect high-point code. Whether or not Ss made errors that affected their summary codes was unrelated to the extent to which they were interested in knowing more about occupations or academic majors they might like. Neither were such errors related to whether Ss felt the occupations suggested by their summary codes seemed reasonable. Only slightly over one-third the Ss actually did feel that the occupations seemed reasonable.
