Regional cerebral blood flow patterns during verbal and nonverbal auditory activation

Current views of the relationship between audition and cerebral function suggest that increases in regional cerebral blood flow (rCBF) would occur in the superior, mid, and posterior portions of the temporal lobes, and that these changes would be more lateralized to the left hemisphere for a verbal than a nonverbal auditory task. We measured rCBF using the xenon inhalation technique in a group of healthy subjects during three conditions: (1) resting baseline, (2) auditory verbal activation (listening for word meaning), and (3) auditory nonverbal activation (listening for reduction of intensity in a series of noise bursts). Both verbal and nonverbal conditions produced highly significant increases in rCBF over the left posterior Sylvian region with a trend for verbal activation to evoke a wider area of flow increase than the nonverbal task.     

Encoding specificity in the alcoholic Korsakoff patient

A previous attempt to improve amnesic Korsakoff patients' retention of individual words resulted in only moderate improvement and, then, only under restricted conditions. It appeared that this occurred because the patients “forget” the instructed analysis of the word as well as the word itself. Consequently, the two experiments reported here sought to provide feature (Experiment 1) or associated (Experiment 2) cues at both input and output. In this manner relatively good performance was obtained, but only when semantic cues were “strongly” associated to the target words. Implications for an encoding specificity interpretation are drawn from these results.     

Word-by-word analysis of observer agreement utilizing audio and audiovisual techniques

The purpose of this study was to compare audio and audiovisual techniques of analyzing stuttering behavior using a recently developed index of agreement (Young, 1975). Twenty speech pathologists identified moments of stuttering for ten adult stutterers using both audio and audiovisual methods. Although no statistically significant differences existed between the two conditions, the listeners had more difficulty identifying moments of stuttering during the audio condition when mild stutterers were used.     

Work roles in death-releated occupations

More occupations than generally realized require the worker to have contact with the dying, the dead, and the bereaved. The opportunity for “leeway” and the desire to provide service are major motivating factors for persons in these positions. The death-related professional, often fatalistic in his own views of his own death, must live up to the social expectations for his role performance while simultaneously being a functioning human being who must encounter death at a personal level and a businessman who must earn his living from working with death-related concerns.     

A validation of the Worker Trait Groups in the DOT

An empirical validation of the 114 Worker Trait Groups (WTG) of the Third Edition of the Dictionary of Occupational Titles (DOT) was performed by comparing the factor structure of the worker trait components of the 114 WTG's with the factor structure of a random sample of 800 of the 4000 jobs used as the basis for the DOT, Third Edition. Six factors were compared and cosines between .8997 and .9657 obtained on the matched factors, thus providing a measure of empirical validity for the 114 WTG's based on the worker trait components.     

Job attitudes of black and white workers: Male blue-collar workers in six companies

A 74-item attitude questionnaire was administered in six companies to 101 black and 87 white male blue-collar employees holding similar jobs in the same company. Differences between the two ethnic groups were not marked, both in terms of job satisfaction and in other respects; Where there were differences the black workers were usually slightly more favorable. However, the picture was not uniform across the different companies.
