If rats are overtrained on a visual discrimination they generally learn the reversal of the discrimination faster than non-overtrained rats. In position discriminations, however, this effect does not generally hold—indeed several investigators have found overtraining to retard position reversal. One of the important differences between the two types of problem seems to be the presence of irrelevant cues in visual discriminations, and their absence in position discriminations. It is suggested that a second important feature of position discriminations is that overtraining usually causes control of the maze running habit to be transferred from external to proprioceptive stimuli, and that successful reversal cannot normally occur until external control is re-established. In two experiments a study by Krechevsky and Honzik (1932) is repeated with certain modifications, with results that support this hypothesis; and a third experiment provides direct evidence of transfer to proprioceptive control in a T-maze. It is shown that this analysis will explain the apparently conflicting results of all recent position reversal experiments.  相似文献

Crises and critical life transitions activate 2 distinct but complementary modes of coping, (a) transforming developmental circumstances in accordance with personal preferences (assimilative tendency) and (b) adjusting personal preferences to situational constraints (accommodative tendency). Assimilative and accommodative tendencies were measured by a questionnaire comprising 2 independent scales (Tenacious Goal Pursuit and Flexible Goal Adjustment). Both scales predict high life satisfaction and low depression and are positively related to generalized internal control beliefs. The scales evinced an opposite relation to age: Cross-sectional analyses on a sample of 890 Ss in the age range from 34 to 63 years revealed a gradual shift from an assimilative to an accommodative mode of coping. Implications for theories of depression and successful aging are discussed.  相似文献

A study is reported in which the relations among normal aging, source amnesia, and frontal lobe functioning were explored. Twenty-four older adults (aged 60-84 years) were tested on their ability to remember where they had acquired new factual information; they were also given the Wisconsin Card Sorting Test (WCST), a test of verbal fluency, and other psychometric tests. The degree of source amnesia in this normal sample correlated with age, verbal fluency, and some measures from the WCST. Source amnesia was not related to Performance IQ, however, or to a measure of fact recall. The implications for the relations among aging, memory, and frontal lobe functions are discussed.  相似文献

This study investigated the effectiveness of paradoxical and non-paradoxical interventions with clients [henceforth known as participants] possessing a high or low sense of humor. Fifty-three test-anxious participants were divided into a low sense of humor group and a high sense of humor group and were assigned to a paradoxical intervention condition, a nonparadoxical intervention condition, or a no-treatment control group. Participants in all groups improved over time but, contrary to the hypothesis, low sense of humor participants improved significantly more with a paradoxical intervention than high sense of humor participants with a paradoxical intervention. There were no differences in improvement due to treatment condition for the high sense of humor group. Low sense of humor participants perceived the counselor as more able to help than did high sense of humor participants. The paradoxical intervention was seen as more surprising than the nonparadoxical intervention. Implications for the use of paradoxical interventions are discussed.  相似文献

The time has come to integrate feminist therapy and knowledge of gender into principles of counseling for both women and men. Gender Aware Therapy (GAT) is such a synthesis. GAT encourages counselors to facilitate the development of women and men through exploration of their unique gender-related experiences. The foundations, principles, stages, and applications of GAT are described.  相似文献
