Holland's theory: Stability of avocational interests

The generality and stability of Holland's vocational choice model was tested by examining preference for avocational (leisure) activity. Based on their responses to the Strong Vocational Interest Blank, college students were placed into one of the six Holland groups. They also indicated preferred leisure activities on questionnaires that were administered at a 9-year interval. Six hypotheses were developed relating Holland groups to particular types of avocational behavior. For example, it was predicted that the Artistic group would be more active in cultural affairs and that the Enterprising group would prefer reading political and economic magazines. The initial test of these hypotheses during late adolescence confirmed five of the six predictions. A follow-up 9 years later confirmed all six hypotheses. These results provide some support for the notion that individuals self-select a variety of situations. Also, the relationships between Holland scales and leisure activity and possible implications for the vocational choice model are discussed.     

Holland high point social types: Is consistency related to persistence and achievement?

This study concerns Social personality types and assesses the relationship of Holland's secondary construct of consistency to persistence in college and academic achievement. The sample consisted of 211 Social subjects who completed the Self Directed Search (SDS) as college freshmen in 1970. Evidence of persistence/nonpersistence and cumulative grade point averages were determined from college records. Hypotheses concerned the relationship of consistency to (a) termination status (persistence/nonpersistence), and (b) cumulative grade point average, for both persisters and nonpersisters. Results indicate that the relationship between consistency and termination status was significant, with high- and medium-consistency subjects persisting in college at a higher rate than low-consistency subjects. The relationship between consistency and CGPA was also significant. Results indicate that for both persisters and nonpersisters in college, subjects with higher levels of consistency achieve higher CGPAs than do subjects with lower levels of consistency. Implications of these findings for academic retention and counseling, as well as for future research, are indicated.     

Values,preferences, needs,work ethics,and orientations to work: Toward a conceptual and empirical integration

There have been comparatively few attempts on either the conceptual or empirical level to integrate values, preferences, needs, work ethics, and orientations to work. A rationale outlining the way these concepts can be related to each other, is presented. It is maintained that these concepts are categories of relations between humans and work. These categories are qualitatively similar and differ principally in the level of generality of the characteristics of work considered. Complete-link cluster analysis is suggested as a method of analysis compatible with the proffered rationale. Two studies are presented with data gathered during the development of two versions of Work Aspect Preference Scale (WAPS). The samples for the two studies both comprised senior high school students, controlled for sex and age, who were administered the WAPS. Study 1 had a sample of 532 while Study 2 had a sample size of 482. Both sets of data were cluster analyzed. Results indicated a very substantial amount of agreement between the two samples, particularly at the more general levels of clustering. The bipartite and tripartite groupings of vocational needs suggested by L. H. Lofquist and R. V. Dawis (Journal of Vocational Behavior, 1978, 12, 12–19) were confirmed as were the findings of J. Mortimer (Sociology of Work and Occupations, 1975, 2, 29–53). Other clusters were also identified with findings from previous research. It is concluded that the investigation of preferences at different levels of generality and the interrelation between these levels shows great promise for both the researcher and the counselor and therefore merits more research effort.     

The mediating effects of career indecision subtypes on career-counseling effectiveness

The purpose of this study was to test the hypothesis that career indecision subtypes serve as a mediating variable in regard to career-counseling effectiveness, and to an attempt to detect two other mediators, i.e., individual- versus group-counseling modes and direct versus indirect test interpretation. In a pre-post design conducted on 149 undergraduate clients who went through a standard counseling process it was found that: (a) Different subtype groups gained differentially in their career decidedness; clients who “lack structure” gained the most from the treatment while clients who “perceive external barrier” and who experienced “personal conflict” gained the least, (b) Neither counseling mode nor test interpretation directiveness had significant effects or interactions with career decidedness. It was proposed that career counseling should be conducted with different contents rather than processes in order to benefit clients with various problem types.     

The corroboration time measure: An implicit confidence judgement

The corroboration time technique is introduced as a means of eliciting covert confidence judgements. A validation experiment is reported in which three measures based upon the corroboration time are compared with overt confidence judgements. It is concluded that the technique yields a valid, sensitive measure of confidence which is as sensitive as an overt confidence judgement to variations in the independent variable, and which is less intrusive in use. It may be used whenever there is a unique correct response which can given as feedback for corroboration.     

Foreperiod and visual stimulus intensity: A reappraisal

The joint effects of stimulus modality, stimulus intensity, and foreperiod on simple RT were investigated. In experiment 1 an interaction was found between stimulus intensity, both visual and auditory, and a variable FP such that the intensity-effect on RT was largest at the shortest FP. Experiment 2 provided a successful replication with smaller and weaker visual stimuli. No interaction was observed with a constant FP, although the visual stimuli were identical and the auditory ones psychophysically equivalent to the visual stimuli of experiment 1.It is proposed that an additive or interactive relationship between stimulus intensity and FP can be inferred only when the mental processes called for by the various uses of FP are simultaneously considered. Another precondition is an adequate sampling of the intensity-continuum with special reference to the retinal size of visual stimuli.     

Predicting persistence,stability, and achievement in college by major choice consistency: A test of Holland's consistency hypothesis

This study examined the relationships between students' level of consistency in choosing a major in college and their persistence, stability, and achievement in a 5-year follow-up. In contrast to the findings of most previous studies, it was found that consistent students tend to persist in college, not to change majors, and that they have higher achievement than inconsistent students. It was suggested that the current findings, which support Holland's theory, were different from the results of previous studies because of the use of behavioral definition for consistency level (actual student major choices) rather than responses to various inventories. The significance of these findings were discussed.     

The predictive efficiency of Holland's SDS summary codes in terms of career choice: A four-year follow-up

This study was designed to investigate the predictive efficiency of the primary and secondary summary codes of Holland's Self-Directed Search for Educational and Vocational Planning (SDS) in terms of expressed career choice 4 years later. In 1974, 126 voiationally undecided high school seniors were given the SDS, followed by a revision of Trow's Vocational Choice Inventory (VCI) in which they were asked to express a career choice or a state of indecision. In 1978, this same group was mailed a posttest VCI; the responses of 84 subjects were then analyzed. The subjects' expressed career choices on both the 1974 and 1978 VCI were compared to the primary and secondary summary codes on the SDS which they had taken in 1974. Inspection of the responses indicated that 21.4% of the subjects had made career choices predicted by their primary summary codes and 51.2% had made vocational choices found among their secondary summary codes. Only 27.4% chose a career area not predicted by their 1974 SDS results. The results of this study appear to lend support to the validity of using the SDS summary codes to predict eventual career decisions.
