The effects of alternatives on the salience of reward allocation norms

In a dyadic bargaining situation there is considerable evidence that the alternative outcomes of the bargainers (if they cannot reach agreement) have important effects on bargaining outcomes. Under the assumption that situational factors affect the nature of the relation between the alternatives of the bargainers and bargaining outcomes, the effects of two factors were assessed: the relative size of the reward to be negotiated (excess of prize minus alternatives) and the magnitude of the difference in the alternatives of the two bargainers. Using college students as subjects, the predictions of two models were also contrasted: the equal excess model and Shapley-w. The relative size of the prize did not have a significant effect on the accuracy of the two models, but the magnitude of the difference in alternatives had marked effects. The results also suggest that the Shapley-w model may be more accurate when the bargainers are relatively inexperienced and cooperatively oriented, whereas the equal excess model may be more accurate when the bargainers are relatively sophisticated and competitively oriented.     

The relationships among cognitive development,locus of control,and gender

Research has shown that perhaps 50% of all adults in this country are not able to perform abstract reasoning tasks described as formal opertions in the Piagetian cognitive developmental framework. Abstract reasoning is related to an individual's ability to perceive contingencies between their actions and subsequent outcomes. This pattern is seen as crucial for the development of an internal locus of control. Fifty-eight male and female undergraduates completed the Rotter Internal-External scale and a Cognitive Developmental Level assessment. For women, a highly significant inverse relationship was demonstrated between cognitive developmental level and locus of control. Women with higher levels of cognitive development were more likely to be internal. For men, no such relationship was found. Such results suggest that locus of control develops differently in men and women.     

The recall and use of belief statements as bases for judgments: Some determinants and implications

When people are asked to report their beliefs in a (target) statement, they may search memory for other, “informational” propositions that bear on its validity, and may use their beliefs in these propositions as bases for their judgments. Several factors were hypothesized to affect the particular propositions that subjects are likely to recall under such conditions. Subjects first familiarized themselves with a list of informational and target propositions. Then, they reported either their beliefs in these propositions or their attitudes toward them. In a second session 1 week later, they recalled as many of the propositions as they could. Both informational and target statements were better recalled when the informational propositions were unlikely to be true. In addition, the target statements were better recalled when the informational propositions associated with them had unclear implications for their validity. Recall of one proposition was more likely to cue the recall of the other when subjects had previously reported belief in the target proposition (rather than attitudes toward it). However, it was more likely to occur when subjects had reported attitudes toward the informational proposition (rather than beliefs in it). The effects of these variables were interpreted in terms of their mediating influence on the strength of association between the informational proposition and both (a) the target proposition and (b) contextual and environmental cues in the situation where target beliefs are reported.     

Effects of alternatives in coalition bargaining

A critical factor in bargaining and coalition formation is the alternative outcomes of the bargainers if an agreement cannot be reached. In some situations bargainers have individual alternatives while in other situations their alternatives must be negotiated with others. The purpose of this study was to contrast the effects of one-person and two-person alternatives on coalition outcomes. The second purpose of the study was to contrast the predictions of four theories of coalition formation: bargaining theory, equal excess model, Shapley value, and a special case of equity theory. The results indicate that one-person alternatives enhance the bargaining strength of the stronger players more than two-person alternatives. The predictions of the equal excess model and the Shapley value were more accurate than the predictions of bargaining theory and equity theory. However, the greater accuracy of the equal excess model and the Shapley value may be restricted to situations in which the bargainers have one-person rather than two-person alternatives.     

Increasing achievement motivation and work productivity in a chronic psychiatric population

The major goal of this study was to determine if social reinforcement for behavior in a simulated work activity would increase achievement motivation, work interest, and simulated work activity production. Forty-five chronic psychiatric patients were randomly assigned to one of three groups: work sample with praise, work sample without praise, and a no-treatment control group. A 3 (between) × 2 (within) analysis of variance was run for each dependent measure, that is, achievement imagery, work interests, and simulated work production. The main effect for the interaction between trials and treatment was significant on each dependent measure. Follow-up Duncan Multiple Range Tests indicated that the praise group showed a significant improvement on each dependent measure, pre to post, as well as significantly greater improvement than the no-treatment control group and/or the work sample without praise group. These results are discussed in terms of the procedure used as a method for increasing motivation and in terms of possible generalization of results to other treatment situations.     

Predictors of organizational commitment: The study of part-time army reservists

A predictive model built upon a multiple role conflict/felt responsibility conceptual framework and containing six previously untested predictors and nine previously tested organizational-related predictors of organizational commitment was investigated. The sample consisted of two battalions of U.S. Army Reserve members. Stepwise multiple regression analysis utilizing a double cross-validation design on each battalion was the data analytic technique. Increased job satisfaction and stronger intent to stay consistently entered each equation as the first and second predictors, respectively. Group cohesion also appeared in more than one equation. The variance explained across the four cross-validated samples averaged .46 and the results were very stable. The importance of the investigation of commitment for this part-time, voluntary organization was discussed, as were future research directions regarding organizational commitment.     

Self-esteem and job complexity as moderators of performance and satisfaction

Self-esteem and job complexity were investigated as moderators of self, supervisor, and peer ratings of performance and satisfaction with work, supervisors, and peers testing balance and activation theories. One hundred and fifty-three registered nurses served as subjects. Measured self-esteem was not significantly related to the performance or satisfaction measures. Rather, the important variable was perceived job complexity as predicted by Scott's activation theory. Self-ratings of performance and satisfaction with work and peers were greatest at optimal complexity with lower values at high and low complexity. Some support was found for self-esteem as a moderator of the relationship between performance and satisfaction measures in line with Korman's formulations.     

Incidental learning in preschool children as a function of level of cognitive analysis

Preschool children's recall and clustering of organized lists of pictures were examined under deliberate instructions to remember or in incidental learning situations. The incidental tasks either required comprehension (categorization, or a rating of pleasantness-unpleasantness) or were formal orienting tasks involving processing in terms of physical features.Explicit instruction to remember and formal incidental instructions did not differ, and both lead to poorer performance than the comprehension activities. Categorization, whether accompanied by explicit instructions to recall, or occurring in the context of a meaningful activity, was no more efficient than categorization in and for itself. With children as with adults, it is the activity of the children which determines depth of processing and subsequent retention, not the intent to remember per se.     

Developmental differences in rehearsal and free recall

The purpose of this experiment was to analyze developmental differences in rehearsal strategies which may mediate the commonly found age effect on free recall. As expected, significant age differences in recall were found; analysis of rehearsal strategies showed that fifth and eighth graders tended to repeat stimulus words immediately after presentation, and not enter items into subsequent rehearsal sets. Adults, in contrast, tended to reenter items for additional rehearsal, and had larger rehearsal buffers. Immediate repetition may have served as additional massed presentation trials, which are less consequential for learning than later reentry of items (spaced trials). It was inferred that children engaged primarily in maintenance rehearsal, and adults in both maintenance and elaborative rehearsal.     

Self-punitive behavior with changing percentages of reinforcement: The proper role of discrimination

Past research on self-punitive behavior has been interpreted as supporting a theoretical éxplanation based on a vicious circle rather than a discrimination hypothesis. Using rats, Melvin (1964) found that self-punitive behavior is not reduced when discrimination is aided by changing the percentage of shock trials from acquisition to extinction. This past research is inconclusive because it is based on a misinterpretation of what is the critical discrimination for extinction, namely the new response-punishment contingency. Using humans, the present study provides evidence that subjects can and do discriminate the change in percentage, but continue to show self-punitive behavior until they make the discrimination that responding results in shock rather than escape.
