Types produce types: An examination of personality development using Holland's theory

This study was designed to test Holland's hypothesis that parents encourage the development of their own personality types in their offspring. Data were collected by personal interviews from three freshmen classes at a large midwestern university. Parent's personality types (occupations) were compared to offsprings' personality types (expressed occupational choices) using the Kolmogorov-Smirnov one-sample test to determine whether or not the comparisons were due to chance. The results indicated that relationships existed between the personality types of fathers-sons, fathers-daughters and mothers-daughters while no relationship was confirmed between mothers-sons.     

Roe's classification and the multidimensional nature of occupational perception

The purpose of this study was to compare college students' perceptions of the similarity of occupations with the groupings suggested by Roe (1956). Subjects were 90 male and 99 female university freshmen. Four illustrative titles were selected from five of Roe's eight groups. Subjects were asked to judge the similarity of each of the possible pairs of titles. The results were analyzed using multidimensional scaling procedures. The data provide partial support for Roe's postulated structure, although the subject's perceptions were generally more complex than suggested by Roe. In particular, the hypothesized circumplex arrangement of groups received only limited support.     

GENERALITY AND SIDE EFFECTS OF OVERCORRECTION1

The effects and side effects of overcorrection for self-stimulatory behaviors of two children in a specialized day-care program were evaluated. For one child, a “hand” overcorrection procedure involving arm and hand exercises was introduced contingent upon inappropriate hand movements and later contingent upon inappropriate foot movements. After “hand” overcorrection was withdrawn for inappropriate foot movements, a “foot” overcorrection procedure involving foot and leg exercises was introduced contingent upon inappropriate foot movements. For a second child, the “hand” overcorrection procedure was introduced contingent upon inappropriate hand movements during a free-play period, and later contingent upon inappropriate vocalizations at naptime. “Hand” overcorrection was withdrawn and then re-introduced sequentially for both behaviors. Several concurrent behaviors were measured to assess multiple effects of treatment. Results for both children indicated the “hand” overcorrection procedure suppressed inappropriate hand movements and inappropriate behaviors that were topographically dissimilar. In addition, inverse relationships were observed between the second child's inappropriate hand movements and appropriate toy usage during free play and between his inappropriate vocalizations and inappropriate foot movements during naptime. Results suggest that overcorrection procedures that are effective for one behavior can be used to reduce the frequency of topographically different behaviors. This finding is discussed in terms of its practical implications for therapists.     

The effect of career education on career maturity

According to Hoyt (1974), career education efforts are underway in almost one-third of all school districts in the United States. Indications are that this trend will continue. However, the question of the effects of career education programs remains essentially unanswered. This study was designed to assess the effects of a career education program on students' career maturity as measured by the Career Maturity Inventory (CMI). A pretest/ posttest design was used. The sample consisted of 480 sixth and eighth grade students, one-half of whom participated in a career education program (experimental), with the remaining one-half in a regular school program (control). The career education students consistently displayed higher posttest career maturity levels, four scores being significantly higher. Significant differences were found in occupational knowledge of sixth graders, occupational planning for both the sixth and eighth graders and in the attitude scale score for the eighth graders. It was concluded that the career education program had a positive effect in increasing students' levels of career maturity.

The effects on induced passive rehearsal and the von Restorff phenomenon on the free recall of normals and retardates

Noninstitutionalized retardates and normal children of equal mental age (approximately 8 years) listened to 11 orders of 20 nouns with no instructions to overtly or covertly rehearse. All subjects were in each of three list conditions: (a) when all words were at the same decibel (dB) level, (b) when the 11th item was at a higher dB level, and (c) when the items were repeated at the same dB level using the rehearsal protocol of Rundus (1971). The normals' overall recall was superior to that of the retardates' recall. Repetition of items had no effect on the performance of either group except in the recency portion of the learning curve and on the initial trial for both groups and the fifth trial for the retarded group. The normal group was more susceptible to the yon Restorff effect than was the retarded group. These results were discussed in terms of the changing and different recall strategies of the two groups.     

Stimulus compatibility effects of an accessory visual stimulus on auditory sensitivity

Studies have reported that an accessory stimulus in a second modality can have a facilitative effect on sensory detection in a primary modality. However, performance declines when the subject has the additional task of reporting on the accessory stimulus. The facilitative effect has been attributed to an arousal or warning process, while the interference effect has been characterized as a result of limited channel capacity. Auditory sensitivity was assessed under accessory visual stimulation. Visual stimulus intensity (arousal), processing demand, and interstimulus compatibility (same or opposite direction of change of primary and secondary stimuli) were manipulated. The results indicated that interstimulus compatibility, not arousal, accounted for the obtained facilitation effect. Interference due to additional task demands was not observed. It was proposed that the facilitation effect was due to selective sensory encoding.     

Foreground and background in dynamic spatial orientation

The dependency of visually induced self-motion sensation upon the density of moving contrasts as well as upon additional stationary contrasts in the foreground or background was investigated. Using two different optokinetic stimuli, a disk rotating in the frontoparallel plane, and the projection of horizontally moving stripes onto a cylindrical screen, it was found that: (1) visually induced self-motion depends upon the density of moving contrasts randomly distributed within the visual field and, with a single contrast area of 1/4 %, is saturated when about 30% of the visual field is moving; (2) additional stationary contrasts inhibit visually induced serf-motion, proportional to their density; and (3) the location in depth of the stationary contrasts has a significant effect upon this inhibition. Their effect is considerable when located in the background of the moving stimuli but weak when appearing in the foreground. It is concluded that dynamic visual spatial orientation relies mainly on information from the seen periphery, both retinal and depth.     

Criterion adjustment and probability matching

Twenty subjects made all possible (136) pairwise-comparison judgments of pattern goodness between 17 five-dot patterns. Using multidimensional scaling and hierarchical clustering analyses, a two-dimensional representation was judged the most appropriate for the derived pattern space. The interpreted structure of the spatial-hierarchical configuration strongly supported previous findings that pattern redundancy is the most salient dimension underlying pattern goodness judgments and that patterns can be partitioned on this dimension according to the size of their equivalence sets, i.e., the number of patterns resulting from rigid rotations in 90-deg increments or reflection. A psychological mechanism that accounts for the effect of pattern redundancy on judged goodness was proposed.
