The Conceptualisation and Measurement of Vocational and Work Aspect Preferences

Attention to values/preferences related to work in the research and practice of guidance counselling has been restricted by at least two factors: firstly, Holland's theory that values are subsumed under vocational preferences; and secondly, the fact that comparatively few adequate measures of values are available to the guidance practitioner. Data are presented comparing measures of vocational and work aspect preferences, which clearly indicate that the two do not overlap substantially. In addition, further data are presented on the validity of the Work Aspect Preference Scale, with respect to course choice. The results of this study suggest that previous theoretical and psychometric obstacles to the research and counselling use of values/preferences related to work are no longer valid.     

Relations Among Racial Identity Attitudes,Perceived Stressors,and Coping Styles in African American College Students

This study expanded on previous research with African American college students at predominantly White institutions by examining the theoretically relevant but unexplored relations among racial identity attitudes and (a) both general and culture-specific stressors and (b) problem-focused coping styles. Ninety African American college students at a predominantly White university completed the Black Racial Identity Attitudes Scale, Black Student Stress Inventory, Problem Solving Inventory, and Problem-Focused Style of Coping Scale. A series of multivariate regression analyses revealed that specific racial identity attitudes were statistically significant predictors of both general and culture-specific stressors. In addition, one racial identity attitude status (immersion/emersion) was a unique predictor of general perceived stressors and problem solving. Results suggest the importance of racial identity schemata as a critical factor in predicting stress and coping responses of African American students at predominantly White institutions. The findings also underscore the utility in distinguishing between general and culture-specific stressors, which traditionally have been ignored in the psychological literature.     

Responding to a positive stimulus by “satiated” pigeons

Skinner (1938) found that rats given discrimination training (Phase I) and then reinforced to “satiation” for responses in the presence of the negative stimulus (S?) (Phase II), began to respond again when the positive stimulus (S+) was reintroduced (Phase III). Experiment I replicated Skinner's finding with pigeons, alternating S+ and S? presentations during Phase III. In Experiment II, Phase II was extended, and Phase III results were similar to those of Experiment I, demonstrating that the recovery of S+ responding could not be attributed to a lax Phase II satiation criterion. In Experiment III, a uniform schedule of reinforcement was maintained throughout the three phases, and results similar to those of Experiment I were found, indicating that renewed S+ responding was not due to the shift in schedule between phases. In Experiment IV, Phase I consisted of discrimination training with two positive stimuli (S+_s and S+_n), and Phase II consisted of reinforcement for responses in the presence of S? and S+_s. During Phase III, significantly more responding was found to S+_s and S+_n than to S?, but no difference in responding was found between the two positive stimuli. In Experiment V, Phase I consisted of simple discrimination training, and during Phase II, responses in the presence of both S? and a novel stimulus (So) were reinforced. During Phase III, significantly more responding was found to S+ than to either S? or So, with no difference found between S? and So responding. Renewed responding to S+ during Phase III in the present experiments is best explained by behavioral contrast developed during Phase I.     

Structural and transient components of memory

The decomposition of free recall serial position curves into permanent and transient components (primary and secondary memory, Waugh & Norman, 1965) is widely accepted. In this paper, a hypothesis is proposed directly relating the permanent memory component to a vector quantity which reflects sequential allocation of attention during encoding. In conjunction with a previously published model for encoding and retrieval in free recall (Hogan, 1975), the hypothesis is shown to break down predicted serial position curves into permanent and transient components, in a manner analogous to but in various ways less restrictive than the decomposition proposed by Waugh and Norman.     

Novelty responding and behavioral development in young,developmentally delayed children

This study examined whether or not a measure of information processing ability based on the discrimination of novel and familiar stimuli was related to behavioral development among developmentally-delayed infants. Two samples of handicapped infants were administered multiple measures of visual novelty discrimination and a battery of assessments which were representative of available measures of development in infancy. The results indicated that, as a group, the developmentally delayed infants were capable of discriminating novel and familiar stimuli. Also, correlational analyses indicated that responding to novelty was related to developmental accessment performance in both samples. This finding is consistent with previous data which indicates that novelty response measures are associated with important individual differences in young children.     

Event-related potential studies of cerebral specialization during reading: I. Studies of normal adults

A number of methodological features were incorporated in a paradigm designed to maximize the likelihood of finding reliable event-related potential (ERP) signs of functional specializations between and within the cerebral hemispheres. Every subject was more accurate in identifying words presented to the right than to the left visual field. The morphology of the ERPs elicited by these words varied considerably as a function of electrode position both within and between the hemispheres. Amplitude asymmetries of ERP components recorded from occipital regions of the two hemispheres varied systematically with the position of the word in the visual field. On the other hand, ERPs from more anterior (temporal and frontal) regions displayed large asymmetries which were in the same direction regardless of the visual field of word presentation. The most prominent such asymmetry was in the negativity in the region 300–500 msec (N410) which was larger in the left than the right hemisphere in every subject. These results demonstrate that in this paradigm which demands specialized language processing ERPs are sensitive to aspects of cerebral organization both within and between the two hemispheres.     

On-line computerized career guidance

The background, rationale, and development of an on-line computerized career guidance system are presented. Special emphasis is placed on the relationship between the conceptual theory and the working design for the system.     

Electrographic correlates of lateral asymmetry in the processing of verbal and nonverbal auditory stimuli

A veraged evoked potentials (AEP) to verbal (digits) and nonverbal (clicks) auditory stimuli were recorded from left and right temporal leads in ten right-handed Ss. With dichotic presentation, there was no significant difference in accuracy of report of the clicks heard in each ear, but significantly more digits were identified correctly from the right ear than from the left. Dichotic verbal stimuli elicited AEP whose early components were of greater amplitude, and whose later components were of shorter latency, from the left hemisphere than from the right. No consistent latency or amplitude differences were observed between AEP from the left and right hemispheres when clicks were presented dichotically.
