An investigation of Holland's vocational theory across and within selected occupational groups

A test of Holland's vocational theory across and within selected occupational groups demonstrated concurrent validity for three of the four groups investigated. Statistically significant coefficients of concordance indicated a degree of agreement among individuals in each of the occupational groups investigated. Statistically significant Page's L statistics indicated that a degree of agreement between the theoretical ordering and the observed ordering of the six types or themes was obtained on three of the four groups tested.     

An extension of Holland's theory to its unnatural conclusion

Herein are recorded the events that led to the complete destruction of the United States in the late 1990's, beginning innocently enough in the 1960's with John Holland's Theory of Vocational Choice.     

An investigation of relative preference for consistency motivation

The present experiment was designed to determine relative preference for fulfillment of consistency motivation. Ninety-two students rated their attraction to, identification with, and idealization of a hypothetical stimulus person who was represented as having fulfilled particular social motives such as approval, power, achievement and consistency. Results confirmed that subjects prefer persons who have satisfied traditional needs more so than others whose consistency desires have been fulfilled. Implications for the role of consistency motivation in social behavior are considered.     

Relationship between academic achievement and measured career interest: examination of Holland's theory

The present study was designed to examine Holland's hypothesis that person-environment congruence relates positively to academic achievement. The sample of 157 nontraditional premedical students completed Holland's Self-directed Search interest inventory. The students were enrolled in the Medical/Dental Education Preparatory Program, which is designed to increase the number of qualified applicants who are underrepresented in the medical profession. Using scores on Holland's inventory students were classified as congruent or incongruent. A cumulative grade point average and a science grade point average were calculated for each student. An analysis of variance supported Holland's Congruence-achievement hypothesis. Congruent students did in fact achieve significantly higher cumulative GPA and science GPA than did incongruent students. Implications for counseling and academic advisement as well as further research are discussed.     

An enhanced examination of Holland's consistency and differentiation hypotheses

The research support for Holland's concepts of consistency and differentiation has been equivocal (Nauta, 2010). To provide a reexamination of these concepts, a new method of operationalizing Holland's constructs of consistency and differentiation using the cosine fit function to the RIASEC score profile is proposed. The relation of these new indices to career certainty, congruence and the moderation of the congruence–certainty relation were examined in a sample of 118 college students (study 1). Support was found for the superiority of the cosine fit definitions of consistency and differentiation over the traditional representations. The cosine fit indices were further examined in a second study on 167 adults examining interest stability over 15 years. The cosine fit indices of consistency and differentiation were related to both occupational stability over 15 years and career satisfaction. The results suggest that the concepts of differentiation and consistency may still have merit but only with more exact methods of specification.     

The congruence problem in John Holland's theory of vocational decisions

John Holland's theory of vocational choice has been a dominant one in careers psychology for many years, especially in North America. A key construct in the theory is congruence between person and environment. Yet research has failed to find as strong a link as might be expected between congruence and outcomes such as satisfaction and performance. This could present a major challenge to the theory. Fourteen possible reasons for the weak associations between congruence and outcome measures are identified and discussed under three broad headings: the theory, the research and the world. It is concluded that the most important reasons are (1) that Holland's measures of people and environments partially neglect some important constructs; (2) that environments have not been conceptualized or measured entirely appropriately; and (3) the data that are used in the calculation of congruence indices are insufficiently precise or comprehensive. It is suggested that Holland's theory and associated measures should be developed further, and that the processual elements of it need more attention.     

Managerial Work, Job Analysis, and Holland's RIASEC Vocational Environment Dimensions

We examined relations between the environmental dimensions underlying Holland's theory of vocational choice and skill requirements, context characteristics, and task frequency ratings for managerial jobs. The Holland environmental constructs were measured by the recently developedPosition Classification Inventory(PCI). The task, skill requirement, and context variables were measured using traditional job analysis surveys. Ten judges provided estimates of the expected correlations between the job analysis variables and the Holland constructs. The profile of observed correlations was generally consistent with the judges’ expectations based on Holland's theory, providing support for both that framework and the construct validity of the PCI. The one Holland dimension for which the data were least consistent with predictions was “Realistic.” Results provide a detailed picture of the work content, skills, and context variables within managerial work that are likely to be associated with the RIASEC dimensions. Implications for management development are discussed.     

Personality Consistency and Perceived Problem-Solving Behavior and Attitudes: An Extension of Holland's Typology

Holland's construct of consistency was used to predict self-perceived behavior and attitudes typically associated with “successful” problem solving. The results tend to support Holland's premise that the higher the degree of personality consistency, the more students perceive their problem-solving behavior and attitudes as successful.     

The relationship between mothers' and daughters' sex-role attitudes and self-concepts in three types of family environment

Assuming that mothers are significant others in daughters' socialization, this study was conducted to determine if significant relationships exist between mothers and daughters regarding sex-role attitudes and self-concepts. Three types of families were sampled: those where the mother was a full-time homemaker, those where she was employed because of economic necessity, and those where she was employed for personal and professional fulfillment. The results indicated significant relationships between mothers' and daughters' attitudes toward marriage, children, and careers, but not self-concepts. Differences were also found between the three groups of mothers and daughters. Mothers who are involved in careers that are personally salient differ from mothers who are employed because of economic necessity and mothers who are full-time homemakers.     

An investigation of hierarchical Bayes procedures in item response theory

Hierarchical Bayes procedures for the two-parameter logistic item response model were compared for estimating item and ability parameters. Simulated data sets were analyzed via two joint and two marginal Bayesian estimation procedures. The marginal Bayesian estimation procedures yielded consistently smaller root mean square differences than the joint Bayesian estimation procedures for item and ability estimates. As the sample size and test length increased, the four Bayes procedures yielded essentially the same result.The authors wish to thank the Editor and anonymous reviewers for their insightful comments and suggestions.     

An empirical investigation of the visual rightness theory of picture perception

This research subjected the visual rightness theory of picture perception to experimental scrutiny. It investigated the ability of adults untrained in the visual arts to discriminate between reproductions of original abstract and representational paintings by renowned artists from two experimentally manipulated less well-organized versions of each art stimulus. Perturbed stimuli contained either minor or major disruptions in the originals' principal structural networks. It was found that participants were significantly more successful in discriminating between originals and their highly altered, but not slightly altered, perturbation than expected by chance. Accuracy of detection was found to be a function of style of painting and a viewer's way of thinking about a work as determined from their verbal reactions to it. Specifically, hit rates for originals were highest for abstract works when participants focused on their compositional style and form and highest for representational works when their content and realism were the focus of attention. Findings support the view that visually right (i.e., "good") compositions have efficient structural organizations that are visually salient to viewers who lack formal training in the visual arts.     

Aggregating preference rankings: An AHP-based approach

The problem considered here involves the selection of an alternative by a group of decision makers in a context that involves the aggregating of votes from a preferential ballot. A popular approach for solving such problems is the well-known weighting problem formulation. However, with such a formulation two issues become of critical importance: (a) the weights should reflect the decision-making group's belief on the importance of each rank position and (b) the weights should accord each alternative a fair (if not its best) assessment. Many researchers have studied this problem and proposed various solution strategies. None of these strategies, however, appears to have adequately addressed both issues. The objective of this research is to develop a group decision-making model that solves the problem in a manner that adequately addresses the two critical issues identified, as well as allows for sensitivity analysis and is fairly robust with respect to the various paradoxes identified in voting systems.     

Utility theory with inexact preferences and degrees of preference

a–b* c–d is taken to mean that your degree of preference for a over b is less than your degree of preference for c over d. Various properties of the strength-of-preference comparison relation * are examined along with properties of simple preferences defined from *. The investigation recognizes an individual's limited ability to make precise judgments. Several utility theorems relating a–b * c–d to u(a)–u(b) are included.     

The development, evolution, and status of Holland's theory of vocational personalities: Reflections and future directions for counseling psychology

This article celebrates the 50th anniversary of the introduction of John L. Holland's (1959) theory of vocational personalities and work environments by describing the theory's development and evolution, its instrumentation, and its current status. Hallmarks of Holland's theory are its empirical testability and its user-friendliness. By constructing measures for operationalizing the theory's constructs, Holland and his colleagues helped ensure that the theory could be implemented in practice on a widespread basis. Empirical data offer considerable support for the existence of Holland's RIASEC types and their ordering among persons and environments. Although Holland's congruence hypotheses have received empirical support, congruence appears to have modest predictive power. Mixed support exists for Holland's hypotheses involving the secondary constructs of differentiation, consistency, and vocational identity. Evidence of the continued impact of Holland's theory on the field of counseling psychology, particularly in the area of interest assessment, can be seen from its frequent implementation in practice and its use by scholars. Ideas for future research and practice using Holland's theory are suggested.     

Laterality effects in risk preference: A test of portfolio theory

A central assumption in portfolio theory of risk preference is that for games with expected value constant the preference ordering of an individual should exhibit a single peaked preference function. This assumption was tested by determining the level of stochastic transitivity satisfied by triples of pairwise preference proportions among eight gambles. In only a small percentage of cases were the predicted levels of stochastic transitivity not satisfied. It was concluded that the results provided strong support for portfolio theory.
