Work planning and performance review as a basis for merit pay decisions: An evaluation

The Work Planning and Performance Review (WPPR) System, developed in a midwestern state as a basis for pay-for-performance decisions in the state government, is described. The WPPR's job relevance was evaluated in one state agency by comparing WPPR scores with scores on a behavioral checklist developed for that purpose. Supervisor and subordinate perceptions of the relevance of the two systems are described. Comparison and perception data indicate the WPPR lacks content validity. Probable impact on the merit pay system is discussed.     

List-strength effect: I. Data and discussion

Extra items added to a list cause memory for the other items to decrease (the list-length effect). In one of the present studies we show that strengthening (or weakening) some items on a list harms (helps) free recall of the remaining list items. This is termed the list-strength effect. However, in seven recognition studies the list-strength effect was either absent or negative. This held whether strengthening was accomplished by extra study time or extra repetitions. The seven studies used various means to control rehearsal strategies, thereby providing evidence against the possibility that the findings were due to redistribution of rehearsal or effort from stronger to weaker items within a list. Current models appear unable to predict these results. We suggest that different retrieval operations underlie recall and recognition, as in the SAM model of Gillund and Shiffrin (1984), which can be made to fit the results with certain relatively minor modifications.     

List-strength effect: II. Theoretical mechanisms

Ratcliff, Clark, and Shiffrin (1990) examined the list-strength effect: the effect of strengthening (or weakening) some list items upon memory for other list items. The list-strength effect was missing or negative in recognition, missing or positive in cued recall, and large and positive in free recall. We show that a large number of current models fail to predict these findings. A variant of the SAM model of Gillund and Shiffrin (1984), involving a differentiation hypothesis, can handle the data. A variant of MINERVA 2 (Hintzman, 1986, 1988) comes close but has some problems. Successful variants of a variety of composite and network models were not found (e.g., Ackley, Hinton, & Sejnowski, 1985; Anderson, 1972, 1973; Metcalfe Eich, 1982; Murdock, 1982; Pike, 1984). The results suggest constraints on the future development of such models.     

The effects of majority size on minority influence

Two experiments investigated the role of majority size (social pressure) in minority influence. Opposite predictions were derived from an attributional account and two social impact models. In Experiment 1 there was a tendency for minority influence to decrease with increasing majority size when the minority argued against gay rights. The results were stronger and clearer in Experiment 2. For pro-abortion minorities, the minority's impact clearly declined as the size of the opposing majority increased. As predicted by the social impact models, this decline occurred during the initial increase of the majority size. The limitations of the mathematical models are discussed.     

An experimental study of the relationship between thoughts and eating behaviour in bulimia nervosa

This study tested the hypothesis that cognitive disturbance has a causal role in the maintenance of disturbed eating in bulimia nervosa. Thoughts about eating, weight and shape were activated in one group of patients with bulimia nervosa (the experimental group) but not in another (the control group). There was an increase in negative self-statements in the experimental group following the experimental manipulation. Food consumption was then measured in a taste test. As predicted, the experimental group ate less in the short term than the control group. Contrary to expectations, they did not subsequently report more objective bulimic episodes as a consequence of this decreased food intake. They did, however, report significantly fewer subjective bulimic episodes.     

Men's and women's self-confidence in persuasive,comforting, and justificatory communicative tasks

The self-confidence of men and women was assessed in three types of interpersonal communicative situations. Participants indicated anticipated level of success, evaluated their performance, and assessed the extent to which the outcome was due to ability and to effort. The most striking finding was higher self-confidence in women than in men in comforting tasks. No difference emerged in level of self-confidence between men and women in persuasive tasks. Men tended to anticipate more success in justifying decisions, but following their performance, did not rate either the quality of the performance or their ability higher than did women.     

Frequency as a moderating variable in self-report measures of negative cognition

Based on responses to the Distressing Thoughts Questionnaire, subjects' most frequent depressive and anxious cognitions were selected and compared with representative low frequency thought statements. The high frequency cognitions were more emotionally intense, uncontrollable and unacceptable than the low frequency thoughts. Although high frequency anxious items were rated as more frequent than high frequency depressive statements, no differences were evident in emotional intensity and controllability. Furthermore thoughts of loss and failure were specifically predictive of dysphoria only when high frequency cognitive items were utilized. The implications of these findings for cognitive assessment issues were discussed.     

Cognitive mediation in general psychiatric outpatients: a test of the content-specificity hypothesis

We investigated the degree of content specificity evident in the negative cognitions associated with anxiety and depression in two large samples of general psychiatric outpatients. Standardized measures of affect and cognition were analyzed in a multiple regression design. As predicted by Beck's (1967, 1976, 1987) cognitive theory of psychopathology, thoughts of loss and failure were specifically associated with depression, whereas cognitions of harm and danger were uniquely predictive of anxiety. In addition, hopelessness was specific to depression and not to anxiety. Dysfunctional beliefs showed no consistent association with either mood state. The implication of these results, as well as related findings, is discussed in terms of a cognitive perspective on the differentiation of emotional disorders. Also discussed are the methodological difficulties encountered in research on cognitive-affective relationships.     

Grade, pubertal status, and gender-related variations in conflictual issues among adolescents

The purpose of this study was to describe adolescent perceptions of conflictual family issues, and to ascertain if the intensity of these issues is associated with adolescent grade in school, pubertal status, and gender. The sample was comprised of 279 junior high and senior high school students. Each participant completed a self-report measure of pubertal status, a demographic questionnaire, and the Issues Checklist. Principal factor analysis with varimax rotation of the Issues Checklist resulted in the retention of four factors accounting for 71.59% of the variance. Stepwise regression analyses were conducted for each emergent factor with grade in school, pubertal status, and gender serving as predictors. The results of these analyses indicated that the intensity of School Issues and Household Behavior Issues is greater among seventh and ninth graders than among eleventh graders. Self-Responsibility Issues were perceived as being most intense among transpubertal adolescents. Finally, boys perceived more intense conflict over Persistent Issues and Concerns than did girls.
