An assessment of manager/subordinate perceptions of performance appraisal effectiveness

This study postulates that performance appraisal will be effective to the extent that managers and subordinates have a shared perception of its purpose and function and the degree to which it meets the needs of both groups. A two part research project was conducted to: 1) identify manager/subordinate perceptions of the purposes served by the formal performance appraisal process; 2) determine the extent to which these purposes are being satisfied in organizational practice; and 3) assess if managers and subordinates have a shared perception of the effectiveness of the appraisal process. The sample for the study included 36 managers and 143 subordinates from a division of a large Midwest service organization. The results were mixed with regard to the appraisal system effectively accomplishing its diverse goals. However, in general, there was support for the notion that both managers and subordinates find the appraisal process to be a worthwhile organizational practice. Approximately 70% of the respondents indicated that they would participate in the appraisal program whether they were required to do so or not.     

RWMODEL: A program in Turbo Pascal for simulating predictions based on the Rescorla-Wagner model of classical conditioning

A Turbo Pascal computer program is described that simulates the Rescorla-Wagner model of classical conditioning. The menu-driven program makes it possible to compute associative strengths for differential conditioning, conditioned inhibition, compound and contextual conditionings, trans-switching, and other designs.     

The Effect of Residence Hall Judicial Pollcies on Attitudes toward Rule-Violating Behaviors1

As part of a longitudinal study of legal socialization (N= 507), a subset of the sample (n= 87) was chosen for an exploratory naturalistic experiment of the effect of manipulated residence hall judicial policies on attitudes toward rule-violating behavior. Freshman students who directly participated in the functioning of their dormitory judicial system (n= 26) expressed attitudes less tolerant of rule-violating behaviors than did freshman students (n= 12) who had no control over how rules were enforced. Students in both of these experimental conditions expressed attitudes less tolerant of rule-violating behavior than did those (n= 49) living in two control dormitories operating under the usual university policies. While noting the problem of confounds inherent in naturalistic designs, the results are interpreted as suggesting that while the imposition of strict rules by an external authority can result in attitudinal compliance, a stronger effect can be achieved by fostering shared values through active student participation in the judicial system. The implications of these findings are interpreted within the context of control theory.     

Problems in the psychiatric treatment of foreign patients

The contribution deals with problems encountered during the psychiatric treatment of foreign patients, particularly with those from developing countries. It has been found that scope for socio- and psychotherapeutic treatment is very restricted and that the frequent necessity of returning these patients to their native countries leads to not unconsiderable conflicts. Questions of transcultural psychiatry are regaining importance in connection with increasing migration.     

Evidence for a possible functional interaction between serotonergic and cholinergic mechanisms in memory retrieval

A total of three experiments were conducted. In Experiment 1, the dose-dependent effects of the pretest administration of the serotonergic agonist alaproclate and the selective muscarinic cholinergic agonist oxotremorine, alone and in combination, were assessed in a one-trial inhibitory avoidance task. A clear dose-dependent enhancement of performance was demonstrated as a result of all three treatment conditions, which could not be explained in terms of nonspecific effects of the drugs on behavior in general. In addition, the facilitation of retrieval performance produced by the combined treatment of alaproclate and oxotremorine was observed at dose levels well below those observed following administration of either compound alone. In Experiment 2 attempts were made to block the enhancements of retention resulting from the different treatment conditions (alaproclate, oxotremorine, or the combination of alaproclate and oxotremorine) by pretreating the mice with either scopolamine (a muscarinic cholinergic antagonist) or quipazine (a serotonergic agonist). The results of these experiments indicate that (a) quipazine completely blocked the enhancement of retrieval resulting from alaproclate but not that following oxotremorine or oxotremorine in combination with alaproclate, while (b) scopolamine blocked the enhancement of retrieval resulting from oxotremorine alone as well as that resulting from alaproclate plus oxotremorine but failed to block the memory enhancement resulting from alaproclate. The present results lend further support to the view that both serotonin and acetylcholine play important roles in memory retrieval. More importantly, the results of the present series of experiments provide additional support for a functional interaction between the serotonergic and cholinergic nervous systems in the mediation of behavior.     

A Program for Training Teachers as Counselors of Parents of Children with Disabilities

The author presents a four-session, in-service training program in which a counselor serves as facilitator. The focus of the program is training teachers to work more effectively with parents of children with disabilities through the integration of counseling theory and special education practice.     

Enhancing and degrading visual stimuli

Several assembly language routines are described for use in perceptual identification experiments on the Apple Macintosh computer with MS-BASIC. These routines are in a machine language library that may be accessed from BASIC. No knowledge of assembly language is required to use the statements. In one method of perceptual identification, stimulus clarification, a mask is gradually removed to reveal the stimulus behind it. The other method, stimulus materialization, displays the stimulus on the screen in a piecemeal fashion. Data are reported from a demonstration experiment in which prior exposure to words enabled subjects to identify those words more easily under impoverished conditions.     

Debunking myths about self-quitting. Evidence from 10 prospective studies of persons who attempt to quit smoking by themselves

This article examines data from 10 longterm prospective studies (N greater than 5,000) in relation to key issues about the self-quitting of smoking, especially those discussed by Schachter. When a single attempt to quit was evaluated, self-quitters' success rates were no better than those reported for formal treatment programs. Light smokers (20 or less cigarettes per day) were 2.2 times more likely to quit than heavy smokers. The cyclical nature of quitting was also examined. There was a moderate rate (mdn = 2.7%) of long-term quitting initiated after the early months (expected quitting window) of these studies, but also a high rate (mdn = 24%) of relapsing for persons abstinent for six months. The number of previous unsuccessful quit attempts was unrelated to success in quitting. Finally, there were few occasional smokers (slips) among successful long-term quitters. We argue that quitting smoking is a dynamic process, not a discrete event.
