Consistent curricular choice and congruence of subsequent changes

Curriculum choices of 324 male and 157 female liberal arts students who took the Strong-Campbell Interest Inventory (SCII) during freshman orientation were classified as congruent or incongruent on the basis of rated correspondence between three-letter codes derived from (SCII) Holland theme scales and expressed curricular choice. The choices of those subjects reporting one or more changes in five semesters were examined for level of congruence using a two-way analysis of variance with repeated measures. While serious methodological limitations are noted, analysis of variance procedures indicated that congruent subjects tended to be more stable, more differentiated, and more academically oriented than incongruent subjects. Among subjects who reported one or more changes, Artistic subjects decreased in congruence while Investigative subjects showed no overall change. Results are discussed in terms of recent theory and previous research.     

Self-esteem,race, and job satisfaction

The present study investigated relationships between self-esteem (SE) and job satisfaction among black and white employees. The sample consisted of 523 (45% black) employees of a large, urban school system. There was a positive relationship between SE and job satisfaction for members of both racial groups. In addition, the correlation between need satisfaction and job satisfaction was stronger for high SE persons than for low SE persons. The relationships between two social reference variables (the perceived satisfaction of other employees and improved standard of living) and job satisfaction were, as predicted, stronger for low SE whites than for high SE whites. Among blacks, however, the social reference variables were strongly related to job satisfaction regardless of level of SE.     

Alleviation of forgetting of discrimination learning

Reactivation treatments intended to alleviate forgetting in rats were tested in two discrimination tasks—instrumental learning with brightness or with spatial location as the discriminanda. For memories acquired 28 days earlier, forgetting was alleviated with both tasks when testing was preceded by certain reactivation treatments. Therefore, the generality of the effectiveness of reactivation treatments for alleviating forgetting is extended to include discrimination learning and response measures other than go, no-go behavior.     

Discriminative vocal conditioning in rhesus monkeys: Evidence for volitional control?

Both emotional and volitional systems are invoked in explaining the control of human vocalizations, but vocal behavior of nonhuman primates is often believed to be totally under emotional control. Monkeys' poor performance on conditioning tasks, especially discriminative conditioning of vocalization (DCV), has been cited as evidence against volitional control. In Experiment 1, rhesus monkeys failed a DCV task in which food was given for vocalizations emitted during an arbitrary visual stimulus, but in Experiment 2, monkeys showed clear discriminative performance when an otherwise comparable shock-avoidance DCV procedure was used. This evidence that monkeys possess some degree of volitional control has implications for the relation between animal vocalizations and the origin of human speech.     

Changing correlates of job involvement in three career stages

The nature of correlates of job involvement over three career stages (i.e., early, mid, and late career) was explored in order to account for the lack of consistency of past empirical work in the job involvement area. Data relating to perceptions of job involvement, job characteristics, job satisfaction, rewards, and individual differences were collected from 332 Canadian transportation ministry employees. Utilizing correlational analysis, support was found for the hypothesis that career stage moderated the relationship of job involvement and various situational, individual difference, and outcome measures. These results are discussed in light of the current literature.     

Investigative versus realistic Holland types and adjustment in theoretical engineering majors

This study tested the sensitivity of J. L. Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) congruence method for predicting differential outcomes in the case of subtle person-environment congruence differences. This question is relevant to engineering programs, where students with adjacent Holland orientations of Investigative (I) and Realistic (R) aspire to complete theoretically oriented engineering majors, such as electrical and mechanical engineering. It was hypothesized that high congruence (e.g., I-type student in I-type engineering major) compared to moderately high congruence (e.g., R-type in I-type major) would result in more positive educational outcomes. A preliminary analysis verified that subgroups of I- and R-type students possessed similar scores on measures of general and math aptitude. Results on both outcome measures favored the high student-curriculum congruence hypothesis. I- compared to R-type subjects demonstrated greater persistence in their initial engineering major over a 2-year period and attained higher grades. Persistence findings replicated across two separate classes of entering students, but academic performance differences were not as consistent.     

Career roles,psychological success,and job attitudes

D. T. Hall's (Careers in organizations. Pacific Palisades, Calif.: Goodyear Pub., 1976) psychological success-based model of career development was investigated using path analyses across three faculty member roles and several performance indices. The model received moderate support for each role. While alternative paths from performance to job involvement and satisfaction with promotional opportunities were observed, they did not contradict the portions of the psychological success model studied.     

Characteristics of career success: An additional input to selecting candidates for professional programs?

It has been argued that selecting students for graduate degrees in professional schools should involve the use of information on a student's potential for “career” as well as academic success. The purpose of this study was to describe the elements of career success of 96 former doctoral students in educational administration and to measure their relationship to conventional academic and individual variables, such as GRE and MAT scores, career experience, age, sex, and quality of reference. It was found that there were no statistically practical or significant relationships between measures of academic success and career success.     

The effects of delay and interference: A speed-accuracy study

This paper examines the effect of (1) delay between learning and test and (2) associative interference on memory retrieval speed. The speed-accuracy tradeoff methodology, which interrupts the retrieval process at various times (0.3, 0.7, 1.0, 1.5, 2.0, and 3.0 sec) after presentation of the test item, provides a means of separating retrieval speed effects from effects on overall memory strength. Performance at short processing times is an index of retrieval speed. Performance given ample processing time is a measure of asymptotic accuracy, or memory strength. Increasing the delay between learning and test or introduction of interference relations lowered memory trace strength, as reflected in asymptotic accuracy. Items tested shortly (about 3 sec) after learning showed a significant speedup in retrieval relative to items tested at a longer (several minute) delay. Further analysis suggested that the delay effect on retrieval was primarily the result of immediate repetition, or testing of the last-learned item. The interference manipulation showed a slight and nonsignificant tendency toward slowing of memory retrieval. The implications of these results for various models of retrieval are explored via simulations. The results of all the simulations suggested a direct-access retrieval process where associations are processed largely in parallel. Contradiction or mismatch information in recognizing new items was important because it provided an explanation for a slight slowing in retrieval due to interference even with a parallel-processing assumption. Faster retrieval for the last-learned item may be the result of residual activation following active processing.
