Seventy-one male employees of three high-technology content product industries in northern Utah were divided into three contrast groups: engineers, engineering-trained managers, and non-engineering-trained managers. The California Psychological Inventory was administered and multivariate analysis of variance performed on seven preselected CPI scales. Results revealed that nonengineering managers scored significantly higher than engineers on scales Dominance, Capacity for Status, Social Presence, and approached significance on Sociability. Engineering-managers also scored significantly higher than engineers on Dominance, and significantly higher than other managers on Psychological Mindedness. A multivariate main-effect significant p < .001 to predict group membership was found. Engineering-managers share with other managers a confident, persuasive, and aggressive self-presentation combined with a preference for leadership roles. Their elevation on Psychological Mindedness, however, suggests a more pragmatic analytical and less intuitive approach to management situations. 相似文献

Individual and organizational correlates of employees who refuse seniority-based promotions in union lines of progression are examined. The sample consisted of 313 production employees of a large manufacturing complex. Correlational and discriminant analyses revealed that age, being female, and number of employees in the department related positively to promotion refusal, while years of education and pay showed a negative relationship. Of these variables, years of education was the strongest predictor. Potential explanations for the results relate to stress avoidance, perceived inabilities, and equity theory. Areas for future research are suggested. 相似文献

Ethical objections to the use of behaviour therapy in homosexuality are discussed. It is pointed out that these objections were often based on a limited view of the aims of the therapy. The need for evaluating such therapy, as it is currently used, is elaborated.Twenty subjects requesting behaviour therapy to reduce compulsive homosexual urges were randomly allocated, half to receive aversive therapy using electric shocks and half to receive covert sensitization. Both groups were studied for one year. There was no consistent trend for one therapy to be more effective than the other in reducing the strength of compulsive homosexual urges, and the response to both was similar to that reported in previous studies. It was considered that aversive therapies in homosexuality do not act by establishing a conditioned aversion, nor by altering the subjects' sexual orientation. They reduce aversive arousal produced by behaviour completion mechanisms when subjects attempt to refrain from homosexual behaviour in response to stimuli which have repeatedly provoked such behaviour in the past. 相似文献

The public debate on recombinant DNA research has ended even though significant issues of public interest remain undecided or untouched. The reason for the termination of other than muted public discussion is not simply the removal of an initial fear of catastrophic biohazards. With the cessation of public debate over such hazards came also the dissolution of most public forums. The ends to which recombinant DNA research and development ought to be directed are not matters of public debate. With the transfer of basic research knowledge to the private sector, that sector's proprietary interests and ownership prerogatives effectively deny any continued public participation in charting the future of genesplicing technology and its application. 相似文献

A distinction is made between functionaland intentionalcontrol in parent-child interaction. These concepts are drawn, respectively, from opérant and cognitive models of interaction process. Experimental evidence is presented that cognitive factors such as expectations or hypotheses indeed affect the relations between parents and their own children. This necessitates a further distinction between long-termand short-termcausal effects: Since changes in parents' expectations for their children may lag behind actual changes in children's behavior, short-term effects inferred from observations of ongoing interactions may not reflect the long-term dynamics of the relationship. 相似文献

Preschool and many older children often have difficulty understanding who carries out the complement action (e.g., to go in sentences such asMary promised John to go; this is so, even though they easily understand this information in sentences such asJohn told Mary to go. C. Chomsky (1969) proposed that children's errors arise from the overgeneral application of a purely structural Minimal Distance Principle. Maratsos (1974), however, hypothesized that children err by overgeneralizing a different principle which he called the Semantic Role Principle. According to this principle, the Goal-Recipient of the spoken message, not the closest noun phrase, is understood as the person who carries out the act referred to by the infinitival complement. The two studies reported here were designed to determine which of these principles children use. Preschool children were taught to understand a specially designed novel construction. The children then acted out sentences containing related but novel uses of the construction such that they would respond differentially according to which interpretive principle they used. The results strongly favored the Semantic Role Principle, rather than the MDP described by Chomsky (1969), or a related, more complex MDP described by Rosenbaum (1967). It is further discussed how children's formulation of the Semantic Role Principle, rather than the MDP, might arise from their prior analyses of related constructions, such as the imperative construction, rather than following from an innate preference, as suggested in Maratsos (1974).This research was supported by the NICHD under Grant #5 R01 HD09112-02 given to M. P. Maratsos. 相似文献

Two studies examined the effects of dispositional self-consciousness on reactance. In Experiment 1, men who were high in private self-consciousness displayed greater reactance responses to a coercive communication attempt (as reflected by attitude reversal) than did men lower in private self-consciousness. In contrast, the effect of public self-consciousness in this context was to inhibit the expression of reactance. In Experiment 2, women high in private self-consciousness exhibited greater reactance responses to a self-imposed threat to their freedom of choice (as reflected by equivocation over two choice alternatives) than did women lower in private self-consciousness. The effect of public self-consciousness in this context was negligible. These findings replicate and extend a previous self-awareness and reactance finding; they provide additional evidence that manipulated self-awareness and dispositional self-consciousness converge on the same psychological entity; and they provide additional evidence that there are important differences between the dimensions of private and public self-consciousness. 相似文献

Naturalistic observations were conducted on 19 acutely ill psychiatric patients in the hospital ward milieu. The study was designed to determine relationships between selected social and environment variables and overt atypical behavior. Patients were observed on an individual basis with time-sampling techniques. In total, 16 pathological behaviors were coded and the most frequent (postural deviance, pace, agitation, hyperactivity, withdrawal, foot shake/body sway, leg swing) were selected in order to determine variation in frequency of these behaviors as a function of the following variables: area within hospital, week of hospitalization, distance between the focal subject and his/her nearest neighbor, number of people in an area, and time of day. Results showed differential changes in pathological behavior as a function of week of hospitalization, number of people in a given area, and distance from the focal subject's nearest neighbor. There was no significant change in the frequency of pathological behaviors as a function of area within hospital or time of day. In addition, most pathological behaviors decreased significantly when patients were engaged in the sending or receiving of verbal behavior. Cluster analyses revealed varying degrees of dissociation between pathological behaviors and social-interaction behaviors. These results support (a) a nonunitary concept of the general category pathological and (b) the view that there are inhibitory effects of social interaction on the enactment of atypical behaviors. Clinical implications of these findings are discussed.R.H.P. completed this research during his tenure as a postdoctocal fellow in the Department of Psychiatry, Human Ethology Laboratory, UCLA (NIMH Fellowship 1 F32MHO7627-01). Support for this research also came from the Veterans Administration. 相似文献
