Pyramid Power in Career Development

Stewart and Nejedlo discuss the use of the Career Development Pyramid as a model for career development and as a practical aid in career counseling. The model graphically depicts the synergistic relations of career choice factors, life-style, self-concept, and the specific job. The authors discuss the relationship between the quadrihedral model and current career development theories. They suggest applied uses of the pyramid and provide a working plan for copy and use by career development counselors.     

New perspectives in temperament/personality research: The “Behavioral” model of the Warsaw group

This paper reviews the theory and research of the Warsaw school of differential psychophysiology, which has modified and extended the typologic model constructed by Teplov and Nebylitsyn. While Soviet theory still favors a relatively inflexible structure of nervous system properties as the biologic basis of individual differences in personality, Strelau and colleagues, in line with the action/activity model of Vygotsky and Tomaszewski, begin with the premise that for every individual there is a specific, genetically determined optimal level of arousal, a necessary background for fullest emotional and intellectual development. The person strives to create this optimal climate through an active process of stimulation control, achieved primarily through enhancement or dampening of reactivity—which describes innate responsivity in the reacting systems to both sensory and emotional stimuli—through various hormonal ‘tuning’ mechanisms and through “appropriate” activity, reflected in different cognitive styles and preference for certain work conditions. Such activities aim to ensure comfortable physical and psychologic environments, in which the individual can avoid conflict and stress. The system regulating and integrating such control mechanisms is the core of personality. Investigations of the Warsaw group on relationships between reactivity and different forms of stimulation seeking/control—risk-taking, work style preferences, cognitive style, defense mechanisms, for example—and between reactivity and tolerance of stress and conflict and their speculations about the neurophysiologic and endocrinologic mechanisms of stimulation control are described, as are a number of questionnaires developed by this group to measure reactivity, the temporal parameters of response, and stimulation-seeking in a variety of occupational and social contexts.     

Strategies of rule discovery in an inference task

It has long been known that subjects in certain inference tasks will seek evidence which can confirm their present hypotheses, even in situations where disconfirmatory evidence could be more informative. We sought to alter this tendency in a series of experiments which employed a rule discovery task, the 2-4-6 problem first described by Wason. The first experiment instructionally modified subjects confirmatory tendencies. While a disconfirmatory strategy was easily induced, it did not lead to greater efficiency in discovering the rule. The second experiment introduced subjects to the possibility of disconfirmation only after they had developed a strongly held hypothesis through the use of confirmatory evidence. This manipulation also failed to alter the efficiency of rule discovery. In the third experiment, subjects were taught to use multiple hypotheses at each step, in the manner of Platt's “Strong Inference”. This operation actually worsened performance. Finally, in the fourth experiment, the structure of the problem was altered slightly by asking subjects to seek two interrelated rules. A dramatic increase in performance resulted, perhaps because information which in previous tasks was seen as merely erroneous could now be related to an alternative rule. The four studies have broad implications for the psychological study of inference processes in general, and for the study of scientific inference in particular.     

On knowing the meaning of words we are unable to report confirmation of a guessing explanation

This experiment investigated Allport's (1977) claim that normal subjects can be induced to make semantic errors of the type characterised by “deep dyslexia”. The procedure followed that used by Allport except that a subject based control for the chance level of semantic errors was included. The results replicated the original finding by producing a semantic error rate of 12·7%. It was shown, however, that this rate was not significantly higher than the calculated chance rate of 11·5%. It was concluded, therefore, that the semantic error rates reported by Allport can be accounted for in terms of a guessing artefact and thus they bear no relevance to the problem of deep dyslexia.     

Levels of Processing and the Cue Overload Principle

This experiment investigates the influence of processing level on the extent of Cue Overload (Watkins and Watkins, 1975, 1976) produced by semantically similar or dissimilar interpolated material. The results showed that semantically similar material only led to increased cue overload if it, itself, was processed semantically. Non-semantic processing of the same types of material failed to reveal any difference between conditions. The results are seen as supportive of the Levels of Processing approach to memory research, since they reinforce the view that different types of orienting task result in qualitative differences in the nature of processing itself. Additionally the results provide some information about the locus of cue overload effects.     

The relationship of extraversion,neuroticism, and sensation-seeking to questionnaire-derived measures of nervous system properties

Five obliquely rotated factor analyses were performed on items from Eysenck and Eysenck’s (1975) EPQ, Zuckerman’s (1975) Sensation-Seeking Scale, and Strelau’s (1972) temperament inventory (STI), administered to 277 subjects (Ss). The analyses were used to examine the relationships between the personality dimensions E, N, L, P and Sensation-Seeking, which pertain mainly to social situations, attitudes and feelings, and questionnaire-derived measures of nervous system properties, which, while validated on experimental indices of nervous system properties derived from Nebylitsyn’s (1972) model, are expressed as characteristic features of social behavior, work style and activity. Four factors were identified—extraversion/strength of excitation/mobility; self-control of affect/stability/caution; strength of inhibition/verbal control/motor expressiveness/ nonmanipulativeness; and sensation-seeking/nervousness. The results offer support for Eysenck’s claim of some identity between excitatory strength and E, for the reported relationship between E and mobility, and for Eysenck’s conditioning postulate. They also suggest that similar temperamental variables underlie individual differences in both social and occupational/motor activity. Since Strelau’s STI items are validated on experimental indices of nervous system properties, it follows that typological characteristics may be inferred from questionnaire data derived from both behavioral categories.
