Is there room for a third dimension in vocational interest differentiation?

Discriminant function analyses involving two vocational interest inventories to differentiate majors of college graduates supported the definition of three dimensions: Business Contact vs. Science, Business Detail vs. Arts, and Service vs. Technical. This common structure between groups emerges only under rotation and is consistent with factor analytic results for differences among people. The implementation of such a three-dimensional scheme for counseling high school students is illustrated. At the theoretical level these results support the position that the structure of vocational interests is more complicated than postulated by the circular orderings of Roe and Holland or by the appealing bipolar dimensions of Data/Ideas and People/Things.     

Reactions of college recruiters to interviewee sex and self-presentation style

College recruiters evaluated the qualifications and employability of either a male or a female applicant for a supervisory position. Half the recruiters in the experiment viewed a videotape of the candidate presenting himself or herself in a passive manner. The other half of the recruiters viewed a moderately aggressive interviewee. Contrary to the hypotheses, the moderately aggressive female was rated as favorably as the moderately aggressive male and the passive male was rated as negatively as the passive female. Although recruiters were as willing to hire a moderately aggressive male as they were the moderately aggressive female, they perceived the female's overall qualifications and her experience/training as superior to that of the male's.     

The sensory basis of avoidance responding in the rat : Relative dominance of auditory or visual warning signals and safety signals

Three experiments determined the relative degree of stimulus control exerted by the elements of a compound auditory-visual stimulus when this stimulus was presented in various temporal relationships to a barpress avoidance response. When the compound discriminative stimulus for barpress avoidance responding consisted of onset of white noise and onset of either light or darkness, the white noise always exerted dominant control. When the compound discriminative stimulus consisted of offset of white noise and onset of light, neither element controlled avoidance responding. On the other hand, when a barpress avoidance response produced a compound feedback stimulus consisting of onset of white noise and onset of either light or darkness, the visual element always exerted dominant control. When the compound feedback stimulus consisted of offset of white noise and onset of light, both elements exerted stimulus control.     

Brain perfusion and neuropsychological test scores: A correlation study in aphasics

In 26 patients suffering from the pure types of aphasias (11 total, 6 motoric, 5 sensory, and 5 amnesic), hemispheric and regional cerebral blood flow were measured and the flow values were correlated with psychological test scores including Wechsler Adult Intelligence Scale (WAIS), Token Test, Benton Test, and word fluency tests. With respect to the flow values, an overall difference between the groups of aphasics was proved by analysis of variance [regional cerebral blood flow (rCBF): F(3,22) = 13.77, p < .001]. The location of mainly impaired brain perfusion was not always confined to the centers within the speech area expected in view of the clinical disturbance, but most patients had neurologic deficits in addition to their aphasia. High correlations were found between the rCBF values within ischemic foci and WAIS subtests, as well as Token Test and word fluency tests. The correlation coefficients calculated between hemispheric flow and the psychological data indicated, in many instances, the same dependency, but did not attain the high statistical significance obtained with the regional values. The results show dependencies of several aspects of mental function upon cerebral perfusion and provide information for possible mechanisms responsible for the disturbance of nonverbal intelligence in aphasics.     

Text comprehension in aphasia

The semantic and pragmatic strategies in the comprehension of spoken texts are investigated in four subgroups of aphasic patients and in normal and brain-damaged controls. Short texts of similar linguistic structure were read to the subjects, who were required to choose the picture, from a multiple choice set of five, that was appropriate to the story. Besides a picture showing the main event of the story, one picture depicted the literal sense of a metaphorical comment, and the others misrepresented semantic functions expressed in the text. With respect to these types of responses, both aphasics and controls exhibited the same pattern of reaction. It is concluded that the redundancy of texts makes up for the difficulties aphasics have in comprehending isolated words and sentences.     

Third party instigation of aggression as a function of noncooperation and veto power

The purpose of the present study was to test the validity of three hypotheses previously offered to explain the attenuating effects of pacifistic noncooperation on instigative aggression. During part one of the experiment all subjects served as instigators; in the second part they actually set shocks for the target. Subjects instigated either a cooperative or noncooperative confederate, and either did or did not have veto power over the confederate's shock selections. Results of the study indicated that all hypotheses, norm-conformity, compliance, and maintenance of power, were viable for subgroups of subjects. Results were discussed in terms of individual differences and the temporarily inhibiting effects of passive resistance.     

Drug use and deviation from self-concept norms

The more the deviation from a sex-and-grade, self-concept score norm (as indexed on a pair-comparisons, adjectival inventory), the greater the incidence of reported drug use. This assertion applies (a) to both sexes (teenagers) for beer and wine, cigarettes, hard liquor, and marijuana, and (b) to males alone for speed and LSD.The first-named author developed the deviancy scale; both authors processed data. In the latter task, they were assisted by Mrs. Edith P. Ferguson, wife of second-named author.     

Explorations using computer simulation to comprehend thematic apperceptive measurement of motivation

The new theory of motivation by Atkinson and Birch (1970), based on conceptual analysis of a change in activity, has been programmed to allow computer simulation of effects of differences in motivation on the stream of operant behavior. Simulation of conditions that exist when people who differ in strength of achievement motive write imaginative stories in response to a sequence of pictures shows that construct validity does not require internal consistency as traditionally supposed. The theoretically deduced differences in total time spent imagining achieving (instead of something else) can postdict input differences in motive strength (i.e., construct validity) even when there is little or no internal consistency reliability as indicated by Cronbach's (1951) alpha computed from theoretically deduced time spent imagining achievement in response to particular pictures. This general point has already been amply documented in 25 years of productive empirical research using TATn Achievement. Now a definitive theoretical refutation of the repeated psychometric criticism of the method is provided. Those who have been moved to dispel fantasies about fantasy-based measures of achievement motivation (Entwistle, 1972) are invited, instead, to examine the shallow theoretical foudation of our traditional myths of measurement.This paper elaborates a report presented August 30, 1975, at the 83rd annual meeting of the American Psychological Association.

Moffett, and financial support by a Rackham Faculty Research Grant (JWA), a National Science Foundation Fellowship (KB), and a Michigan Student Medical Research Grant (LHP).

On dreaming at sleep onset.

The position that dreaming occurs exclusively during REM sleep, which has its first onset after sixty to ninety minutes of nonREM sleep, has been effectively refuted in sleep laboratories but remains uncorrected in the psychoanalytic literature. Examples of hallucinatory activity occurring during the sleep onset period and during a brief nap are shown to have all the characteristics of dreams, including latent content related to repressed material from childhood.
