Using conjoint-measurement models to investigate a theory about probabilistic information processing

A theory of how opinions are formed and revised on the basis of probabilistic evidence is presented. The decision maker is viewed as a limited information processor who attends to the dimensions of a sample of equivocal information in a sequential fashion, beginning with the most salient dimension and continuing in decreasing order of salience. The contribution of each dimension level to the final opinion depends on the strength of association between that level and each of the two hypotheses under consideration. This theory is represented formally as an additive-difference model, various special cases of which correspond to other algebraic models in the literature. Two of the special cases were empirically investigated under varying levels of experience and payoffs, using the techniques of conjoint-measurement theory and ordinal data from individual subjects. The data provided reasonably good support for the models under all conditions investigated, and in addition showed interesting effects on salience and on processing of the independent variables.     

Strong Vocational Interest Blank basic interest clusters and occupational satisfaction

A Q-factor analytic technique applied to the Strong Vocational Interest Blank (SVIB) basic interest scales of 156 males yielded three bipolar factors described as conceptual (applied vs theoretical thinking); interpersonal (people vs things); and volitional (autonomy vs structure). From these results the investigators constructed a model for categorizing occupations into corresponding vocational areas: managerial vs academic, social vs physical sciences, and professional vs technical. Each individual's primary interest area and occupational status relative to the six corresponding areas was then determined. The degree of fit between interests and job categorization related significantly to ratings of job satisfaction (p < .001). Those findings are complementary to Holland's notion that interests are expressions of psychological needs and to Lofquist and Dawis' perception of interests and jobs as needs and need reinforcers.     

A comparison of dichotic and visuo-acoustic competition in hemispherectomized patients

Following hemispherectomy, patients performing dichotic listening tasks have great difficulty reporting items presented to the ear ipsilateral to their intact hemisphere. One possible cause is an attentional imbalance which, when competing inputs are received from both sides of space, restricts the patient's attention to the stimulus contralateral to his remaining hemisphere. If this explanation is true, then a similar ipsilateral ear decrement should occur when a competing visual stimulus is presented in the contralateral field. In the present study, however, hemispherectomy patients easily reported a digit presented to the ear ipsilateral to their intact hemisphere despite the concurrent presentation of a visual digit to their contralateral field.     

Performance as a function of resultant achievement motivation (perceived ability) and perceived difficulty

Subjects worked on a task which was described as either easy or difficult. When the task was thought to be difficult, Ss high in resultant achievement motivation performed better than those low in resultant achievement motivation. However, when the task was perceived as easy, the high motive group performed worse than the low group. These results confirm a prediction from Kukla's attributional theory of performance, in which resultant achievement motivation is conceived as a measure of perceived ability. They are not, however, deriveable from Spence's theory of the effects on performance of objective task difficulty, nor from Weiner's hypothesis concerning the motivational effects of success and failure. On the other hand, Kukla's theory provides an explanation for both the data usually cited in support of Spence's position and those taken to confirm Weiner's hypothesis. The relationship between the present results and Atkinson's theory of achievement motivation, which also hypothesizes an effect of perceived difficulty on performance, is discussed.     

Interpersonal problem-solving skills training with aggressive young children

The purpose of this study was to evaluate the efficacy of an interpersonal problem-solving training program with aggressive young children. There were 13 children in the experimental group and 11 children in the contact control group. Both experimental and contact control group children were evaluated at pretest, posttest, and follow-up on the Behavioral Interpersonal Problem Solving Test (BIPS). Experimental group subjects were exposed to the interpersonal problem-solving skills training program for 50 training sessions. The contact control group participated in reading-story sessions during the same time period. Results and discussion reflect the efficacy of the training procedure and the nature of the change in interpersonal problem-solving behavior in aggressive young children.     

The Individual Psychology of Alfred Adler: Toward an Adlerian vocational theory

Within the past couple of decades, the Individual Psychology of Alfred Adler has become increasingly popular among consultants, educators, and psychotherapists alike. The approach also has gained the attention of several vocational researchers, and some vocational investigations on Adler's theory have appeared. Unfortunately, such empirical studies have been all too few, seemingly because no articulated framework exists of an Adlerian vocational theory. In this article, an Adlerian vocational theory is proposed. Specific hypotheses and corollaries, each derived from the substantive base of Individual Psychology, are presented and explained.     

Preference for modes of dispute resolution as a function of process and decision control

Research on procedural justice has suggested that the distribution of control among participants can be used to classify dispute-resolution procedures and may be an important determinant of preference for such procedures. This experiment demonstrates that control can be meaningfully divided into two components: control over the presentation of evidence and control over the final decision. The experiment placed subjects (law students and undergraduates) in a situation of conflict and varied two between-subjects factors: (1) Role, whether subjects expected to role-play third parties (law students) or litigants (undergraduates), and (2) Orientation, whether individuals focused on equity claims (appeals to a norm of fairness) or legal claims (appeals to a strict, legal interpretation of events). As a control, a third-party neutral-orientation condition was included. In addition, subjects were presented with four dispute-resolution procedures which varied in third-party control over the presentation of evidence (Process Control) and third-party control over the final decision (Decision Control) as within-subjects factors. Results revealed that both litigants and third parties preferred high rather than low third-party decision control. Litigants with an equity orientation preferred low third-party control over the presentation of evidence, particularly when third parties had high rather than low decision control. Third parties and litigants with a legal orientation preferred low rather than high third-party process control only when there was high third-party decision control. Litigant preferences were more affected by variation in process control than variation in decision control while third-party preferences were more affected by variation in decision control than in process control. As a check on external validity, military judges given a neutral orientation were asked to evaluate and express preferences for the four dispute-resolution procedures. Their results were not detectably different from those of the law students who role-played third parties in the main portion of the study.
