A configural approach to the use of the strong vocational interest blank with student engineers

SVIB profiles of 1169 freshmen entering a college of engineering were grouped according to total occupational scale profile similarity into 28 code types. Mean scores or percentages for the individuals in each code type were compared to base rate values for income variables including ability, personality, and socioeconomic data and outcome variables including academic progress, choice of major, counsel-seeking behavior, and place of residence. The data for four code types were presented together with examples of how the results might be used by a counselor. The investigators concluded that SVIB profile types can be useful in acting as moderator variables to predict student characteristics, and that total profile analysis of the SVIB occupational scale merits further attention.     

Effects of density,activity, and personality on environmental preferences

The effects of room density, type of ongoing activity (party vs studying), and a personality variable (“personal space” or the distance which subjects place between themselves and others) on room liking were investigated. Results supported the prediction that type of activity is an important determinant of whether a high or low density setting is preferred. Evidence was also presented that a mediator between activity type and density preference is whether the presence of other people facilitates or inhibits the individual's goals in the setting. Personality factors also influence density preferences: Close standing Ss preferred a high to a low density setting; far standing Ss showed an opposite preference pattern, but only in the party condition. Correlations between Ss' personal space scores and several background and personality variables are also presented.     

Bound morpheme loss errors in normal and agrammatic speech: One mechanism or two?

Loss errors involving bound morphemes in normal and agrammatic speech are examined to determine if all errors can be due to a single processing problem. It is concluded that two problems are present. First, there is a general problem with accessing bound morphemes (or forms containing bound morphemes), leading to the production of the base form. Second, there is a syntactic problem involving agreement. In agrammatism, the first problem is differentially exacerbated. Implications for normal and agrammatic speech are examined.     

Relative influence of sex composition on job desirability

The purpose of this study was to examine the relative influence which the sex composition of a job exerts on its perceived desirability. The influence of job sex composition was studied in relation to three other factors: security, suitability of type of work, and company recognition. Ninety-five college students rated 108 job profiles on desirability based on various combinations of the four factors studied. The results indicated that sex composition exerted the least influence on job desirability while security and suitability of type of work exerted the greatest influence. It is suggested that past research focusing on the sex composition of a job as a determinant of its desirability has produced findings which are primarily a function of the research method utilized.     

Response probability and similarity of retrieved response tendencies as determinants of response suppression difficulty

The primary objective of this study was to test the validity of the here labelled ‘suppression-time’ assumption which contends that the more difficult the response suppression operation, the longer the time required for its successful implementation. A secondary interest addressed the possibility that output suppression difficulty would be influenced by the level of response-response (R-R) compatibility existing between retrieved response tendencies. Two basic requirements confronted subjects within an experimental session: (a) dual-initiation (Dual-I) of paired arm movements, (b) initiation/suppression (I/S) of retrieved outputs, the irrelevant response being suppressed, the relevant output initiated. RT(I/S) magnitude and failure-to-inhibit error frequency increased as response probability increased, thereby providing support for the ‘suppression-time’ assumption. But R-R compatibility degree variations, when realized, did not consistently affect response suppression difficulty.     

Effects of performance expectancies created by peer comparison as related to social reinforcement,task difficulty,and age of child

Children in kindergarten-first grades and fourth-sixth grades (6 and 10 years of age, respectively) participated in one of two experiments and performed either a simple motor task or (for older children only) a two-choice simultaneous discrimination task at two difficulty levels. Children received either positive, negative, or no peer comparison statements (describing how other children their age had allegedly performed) and either praise, silence (in Experiment 2 only), or criticism on a fixed-interval 20-second schedule throughout the task. Young children were more responsive to adult evaluation of their performance than to peer comparison. Expectancies created by peer comparisons affected older children's motor performance most if they received reinforcement contrary to the expectancy. In situations requiring greater cognitive ability, older children, particularly boys, responded to the performance expectancies created by positive peer comparison. Older boys, compared with older girls, seemed to be more sensitive to peer comparison and social reinforcement.     

Visuospatial competency, handedness, and cerebral dominance

The present study addressed the question of Levy's (1974, Psychobiological implications of bilateral assymetry. In S. Dimond &; J. G. Beaumont, Hemispheric function in the human brain, NY: Halstead. Pp. 121–183.) proposal that left handers would have lowered spatial skills relative to verbal skills. In the first part of the study, performance on the PMA (visuospatial subtest) and WAIS Block Design subtest were compared between right and left handed high school and college samples. No support could be found for deficient visuo-spatial performance in the left handers. In the second part of the experiment, no relative impairment of visuospatial skills was found when subjects were classified into predicted speech dominance groups on the basis of a dichotic listening task and/or a visual half-field task. An extreme groups comparison of the most left dominant and most right dominant groups again yielded no significant differences in visuo-spatial performance. Finally, the relationship between degree of speech lateralization and visuo-spatial skills was examined. Only partial support for differences in cerebral organization for speech in left handers was found in the college sample.     

Interference effects in an auditory Stroop task: congruence and correspondence

Two auditory Stroop experiments are reported in which subjects responded vocally to the gender of the speaker of stimulus words. The interference effects found were broadly similar to those of a manual-response auditory Stroop paradigm although response-set effects appeared to operate in the data. In all experimental conditions responses were slower to stimulus words which named potential responses than to those words which did not. Such effects have not been found in previous manual-response experiments and it is suggested that the relatively high degree of S-R and of ideomotor compatibility in the vocal response task, compared with the manual task, may be responsible for this difference between the paradigms.The second experiment enabled a comparison to be made between the effects of congruence between relevant and irrelevant elements of the Stroop stimulus and the effects of correspondence between the response and the irrelevant aspect of the stimulus. A predominant influence of congruence was found when the subject responded using words semantically related to speaker gender, but an effect of correspondence was obtained when an arbitrary pairing of response word and speaker gender was required.
