Career development of special populations: A framework for research

In view of the recent interest in the career behaviors of diverse groups of individuals, this article presents a model for conducting research on the career development of special populations. Available research paradigms are reviewed in terms of their potential impact on such efforts. An alternative framework, designed to make maximum use of available data sources while minimizing potential theoretical bias, is offered. An illustration of research conducted within the recommended framework is presented in which the impact of a variety of career-related variables on the attitudinal and cognitive aspects of vocational maturity is examined from the perspective of two special population groups, disabled and disadvantaged college students. Drawing upon previous research findings, variables under consideration included level of scholastic achievement and endorsement of rational, intuitive, and dependent decision-making styles. Also included were two population-specific variables related to the characteristics of membership in each of the two special groups. The regression analyses conducted to explore the relationships between vocational maturity and these predictor variables indicate, in general, that variance in the attitudinal and cognitive factors of vocational maturity can be at least partially explained by the variables considered. However, the relative contributions of the predictors and the resulting proportions of variance explained differs according to which population and which criterion factor is under examination. These findings are compared with those emerging from previous research, and implications for future efforts are discussed.     

The development of career choices: The relationship between patterns of commitment and career outcomes in adulthood

This study was designed to examine the theoretically predicted adult career outcomes of individuals who engage in different developmental patterns of commitment to choice. It was hypothesized, based on D. E. Super's formulations, that those who engage in increasing commitment and who do not revert to earlier behaviors would experience the most desirable outcomes in adulthood. This hypothesis was tested using an analysis of longitudinal data in relation to career outcomes at two points in adulthood. Minimal support for the hypothesis was found in combination with some findings to suggest that developmental patterns of increasing commitment may not lead to the predicted desirable outcomes. Implications for theory revision and future research are discussed.     

Decision making styles and progress in occupational decision making

This study provides a reexamination of the role of different decisional strategies in facilitating progress in occupational decision making. Although the assumptions that a rational decision making style is the preferred mode of vocational functioning has been endorsed in a variety of career theories and interventions, there has been conflicting evidence about the validity of this assumption. To examine the role of different decisional approaches in the progress of making an occupational decision, the rational, intuitive, and dependent decision making style scores of 71 undergraduate students were used to predict progress in occupational decision making. The results of the regression analyses failed to provide support for the assumption that a rational style is the most effective in accomplishing this careerrelated task, but indicated strong support for the conclusion that the use of dependent decisional strategies is damaging, particularly in early stages of the decisional process.     

Immediate and delayed recognition of visual stimuli in poor and normal readers.

The present study investigated the hypothesis that specific reading disability is attributable to inadequate visual memory. Previous research had demonstrated that poor readers sustain no basic dysfunction in visual perception, but there was need to evaluate the possibility that deficiencies in letter and word recognition result from disorder in long-term visual storage. Adopting a format employed in a previous study, randomly arranged Hebrew letters were presented to poor and normal readers unfamiliar with Hebrew, and both groups were asked to demonstrate retention for these stimuli on three separate occasions: immediately after initial presentation, 24 hours later and 6 months later. As a control measure, the performance of the non-Hebrew subjects was compared with that of normal readers familiar with Hebrew letters. It was found that retention in the non-Hebrew groups was equivalent under all of the temporal conditions, but the performance of both was poorer than the Hebrew groups under the immediate and 24-hour conditions. However, none of the reader groups differed in the case of retention after a 6-month delay period. It was concluded that deficient visual memory is an unlikely source of specific reading disability, and alternative explanations of the disorder were considered.     

An integration of shifts toward risk and caution in gambling situations

Findings have been reported and replicated indicating group-induced caution at the racetrack and group-induced risk in blackjack gambling. The present research examined the effects of two consistent differences between the blackjack and racetrack situations: (a) the amount of money available to groups versus individuals; and (b) the number of bets made in the postbaseline session. It was found that group-induced caution can occur in the blackjack setting if groups have larger stakes than individuals, as was the case in the racetrack studies, and that this effect disappears over trials, due to group versus individual differences established in the previous blackjack studies. Since current explanations of choice shifts cannot account for the observed trial effects, it was suggested that traditional choice-dilemma material, on which these explanations are largely based, be examined for such effects. Implications of the possible outcomes of such an examination for current group polarization theory were discussed.     

Effects of directiveness of instructions and surveillance on the production and persistence of children's donations

All subjects earned tokens for correct size judgments and observed a model who had previously earned tokens at the same task donate some of her earnings. Children were subsequently given an opportunity to donate some of their tokens to children at another school. The opportunity to give occurred in presence (surveillance) or absence of the experimenter and after being presented with either directive (you must give) or permissive (you can give if you want to) instructions. Directive instructions and surveillance both produced greater initial giving for all children. In a second session with no modeling, no surveillance, and no further instructions, earlier directive instructions also produced greater persistence of giving for all children. Permissive instructions produced greater reductions in giving over time for boys than for girls. The present findings suggest that directive instructions produce greater initial giving and that donating persists better under these more explicit conditions.     

Is social comparison irrelevant for producing choice shifts?

After 15 years of research on group induced shifts in individual choice, two hypotheses, social comparison (involving image maintenance) and persuasive arguments (involving attitude change), have emerged as the leading explanatory contenders. Burnstein and his associates have recently reported a series of studies that they feel clearly establish the persuasive arguments hypothesis as the best explanation for the shifts. The present paper takes issue with their conclusion. A study is presented that supports a social comparison interpretation of one of the experiments reported in Burnstein and Vinokur (Journal of Experimental Social Psychology 1973, 9, 123–137). In addition, a critical analysis of several other key studies reported by Burnstein and his associates yields the conclusion that neither hypothesis completely accounts for the available data. Rather, both image maintenance and attitude change processes may operate in a complementary manner, with persuasive arguments facilitating the shifts motivated by social comparison. Parallels are drawn between the factors that affect choice shifts and those that affect conformity behavior.     

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.     

Generalized and lateralized effects of concurrent verbal rehearsal upon performance of sequential movements of the fingers by the left and right hands.

College student subjects performed a sequential typing task requiring bilaterally synchronized movements (Experiment 1) or unilaterally synchronized movements (Experiment 2) singly, and concurrently with silent and vocal rehearsal of verbal lists varying in redundancy. Rehearsal interfered with bilaterally synchronized movements more when the right hand was leading the sequence than when the left hand led, and with movements of the right more than the left hand in unilaterally synchronized movements. Results are interpreted in terms of intrahemispheric and general capacity competition between the concurrent performances.     

Free recall of concrete and abstract words in poor and normal readers

The present study compared poor and normal readers in second and sixth grade on free recall of concrete and abstract words. On the basis of the assumption that memory for abstract words relies more heavily upon linguistic coding ability than does memory for concrete words, it was expected that poor readers would have much greater difficulty on recall of abstract words than would normal readers, but would more closely approximate the normal readers on recall of concrete words. The hypothesis was confirmed at the second-grade level but not at the sixth-grade level, wherein the magnitude of group differences on concrete words was comparable to that on abstract words. Post hoc analyses of intrusion errors suggested that the linguistic coding hypothesis may be a viable explanation of reader group differences on memory tasks only at lower age levels.     

Three types of schemata in children's recall of cohesive and noncohesive text

Children, ranging in ages from 7.3 to 9.6 years, were identified according to the type of schemata structure they used to recall picture sequence events. These children were then required to recall several written text passages representing four different conditions: (1) theme first paragraphs, (2) theme final paragraphs, (3) paragraphs with no theme but having thematic structure, and (4) paragraphs with no theme and no thematic structure. It was found that the manner and the amount of the child's recall were a function of how the child's schemata structure interacted with a given paragraph structure. The implications of these findings are discussed in terms of the generally unquestioned assumption that only one “ideal” text grammar is needed to describe children's schemata for processing test.     

Self-presentation and drive in social facilitation

Social facilitation refers to cases in which the presence of others increases the probability of certain responses on the part of an independently operating individual. Drive theory attributes these effects to an unconscious facilitation of dominant responses, as defined by Hull-Spence learning theory. Self-presentation explanations posit changes in motivation and cognitive strategies that result from an increased concern with favorable private and public images. The present paper reviews evidence and presents an experiment indicating both points of view are valid, but that neither perspective by itself can account for all relevant data.
