This paper explores the effects of the psychoanalytic candidate's role, supervision, training analysis, office setting, and emerging professional identity on his clinical work. The strains associated with institute candidacy and how these may be perceived by patients are explored. The author suggests that further study of the process of becoming an analyst could ultimately improve training.  相似文献

The development of conservation skills in tasks dealing with temporal and nontemporal concepts was investigated. Contrary to findings of previous researchers, time conservation tasks presented few difficulties for children from a non-technological culture. Consistent with the results of previous research, however, time conservation tasks did appear to be more difficult than related tasks employing similar materials.  相似文献

Two studies found that left-handed children had significantly poorer academic records than did right-handed children, though the effect was small. Study 1 provided evidence that, for some academic disciplines, the important difference appeared to be between those children whose family history of handedness was concordant with their own handedness and those children whose family history of handedness was discordant with their own handedness. The inclusion of gender in asymmetry research was bolstered by Study 2. When predicting idiosyncrasies in left-handers' cognitive performance, it should be borne in mind that left-handers form a minority group as well as a neurologically distinct one.  相似文献

Selection, evocation, and manipulation   总被引:10,自引:0,他引:10  
This article proposes three key mechanisms by which personality and social processes are intrinsically linked. Selection deals with the manner in which individuals choose to enter or avoid existing environments. Evocation is defined by the ways in which individuals unintentionally elicit predictable reactions from others in their social environments. Manipulation deals with the tactics that individuals use intentionally to alter, shape, exploit, or change the social environments they inhabit. Empirical findings from 57 dating couples (undergraduates), and previous research within social, personality, and developmental psychology, are used to illustrate the heuristic value of this framework.  相似文献

ABSTRACT A simple parable is introduced that serves as an analogy to the private/public self-focus distinction The analogy elucidates that the reliability of the effects observed by the private/public research direction is not the focus of the Wicklund and Gollwitzer critique Rather, the critique questions the validity of the explanations offered More importantly, the analogy implies the conclusion that construing social dependency as an issue of self-focus does injustice to both the social dependency and self-focus concepts  相似文献

Modulation of the responses to perturbation applied during different phases of three rhythmic movements in humans-running, cycling, and hopping-was studied. The perturbation was an electrical stimulus. The results showed gating and modulation of the responses in both ipsi- and contralateral limb muscles. The responses during running and cycling were only excitatory in nature, while during hopping an inhibitory response was observed. These responses were not correlated with the normal activity during the movement. The latency of the response in general was not altered for different stimulation phases. The alterations in the step cycle demonstrated overt behavioral changes due to the responses. There were differences between the responses observed during these movements and walking. In running, the major adaptation to perturbations appears to be in the contralateral side as seen in the changes in the step cycle. During cycling (except for one phase) and hopping, the same set of muscles was activated in response to perturbation. This represents a simplifying strategy in response organization. The dependency of the response on the task characteristics, postural stability requirement, and external constraints imposed on the subject is discussed. These studies provide insights into task-dependent strategies adopted by the nervous system to meet unexpected perturbation during rhythmic movements in humans.  相似文献
