Two auditory signals were presented in random sequences in which the more intense signal came on.2, .5, or.8a/the trials. Each trial began with an intermediate tone which was identified in the instructions as either the standard for comparison or simply as a warning tone. Half the Os were instructed to discriminate whether the signal was “louder” or “softer” than the standard, the other half to recognize which signal had been presented. For both discrimination and recognition tasks, the total proportion of ldlouder” judgments was independent of the presentation probabilities, accuracy for each signal varying inversely with its probability of presentation. These results suggest strict limitations on the response optimization posited by theories of signal detection. 相似文献

Physically disabled and non-disabled high school seniors' educational and vocational aspiration-expectation discrepancies were compared. No significant differences were found when the two groups were matched for cumulative GPA and level of father's occupation. GPA's and father's job levels of disabled students were significantly lower than those of the non-disabled. When not matched, disabled students' vocational aspiration-expectation discrepancies were significantly higher than those of the non-disabled. Higher aspiration than expectation for the highest vocational and educational levels, professional training, and employment were the major sources of differences expressed by seniors. 相似文献

An adaptation-level model for memory was tested by interpolating different weights between the standard and comparison weights. The results suggest that the model should be modified to account for the general tendency to use alternative categories of judgment with equal frequency. In terms of the modified model, memory for the standard shifts toward the value of the interfering stimulus, the magnitude of shift being proportional to the difference between the interfering stimulus and the value the memory would otherwise have had. 相似文献

This study was designed to analyze whether Mental Rotation (MR) played a role as a mediating variable for sex-related differences in Visualization (VZ). Two psychometric tests measuring MR and VZ were applied to a representative sample of 309 males and 390 females in their last year of high school. Three non-zero correlations between sex and MR, sex and VZ, and MR and VZ were found, and the effect of sex on VZ was eliminated when MR was introduced as a covariable. When three subgroups of different VZ ability were made by dividing up the VZ distribution by the first and third quartiles, sex-differences were only found for the high-scorers group, for which previous results were replicated. Results clearly indicate that MR is a plausible mediator variable for sex differences in VZ when such differences do exist. Theoretical, methodological and practical consequences of these results are discussed. 相似文献

Adult Attachment Styles, the Desire to Have Children, and Working Models of Parenthood 总被引:1,自引:0,他引:1

ABSTRACT College students who had yet to marry and begin a family were asked about their desire to have children and their beliefs and expectations about themselves as parents (Study 1) and the characteristics of their prospective children (Study 2). Persons with more avoidant and anxious-ambivalent models of close adult relationships harbored more negative models of parent-hood and parent-child relationships. These findings indicate that working models of parenting and parent-child relationships form well before marriage and the birth of children and that these models are systematically associated with attachment styles in adult relationships. The findings also suggest ways in which insecure attachments between child and parent may be influenced by the caregiver's models of parenting and parent-child relationships. 相似文献

In his writings on teaching, Isreal Scheffler has argued for the close connection between teaching and reason, an argument which can be summarized by, Teaching is. . an initiation into open rational discussion. This essay examines Schefflier's thesis in the light of criticisms drawn from feminist writings on teaching. It is argued that Scheffler's thesis is consistent with a view of teaching in which it can be achieved through kindness, good example and the efficacy of unconscious imitation, characteristics of the private, reproductive processes typical of women. It is then argued that Scheffler's concept of teaching is compatible with views of education that try to do justice to both reason and emotion, mind and feeling. 相似文献

Tested a theoretical model on the effects of social role identity, illness intrusion, and competence on psychological well-being among 109 low-income Latinas with arthritis. All six roles studied were rated as highly important identities. Sex-role nontraditionalism was associated with less importance of the homemaker, mother, and grandmother roles. Negative affect increased as a function of intrusions into valued identities. Having important role identities contributed to feelings of competence (i.e., self-esteem and self-efficacy), which in turn, contributed to psychological well-being. Competence also mediated the effects of pain, identity, and illness intrusions on psychological well-being. Results suggest competence processes play an important role in well-being. 相似文献

The current literature suggests that individuals who chronically abuse alcohol exhibit a wide variety of cognitive deficits
resulting from cerebral dysfunction that is either directly or indirectly related to their alcohol consumption history. Cognitive
deficits have been hypothesized as having implications for standard alcohol treatment efficacy as they may directly affect
cognitively impaired individuals’ abilities to utilize various treatment modalities. Although evidence is accumulating that
suggests this is actually the case, the majority of alcohol treatment programs neither directly consider the impact cognitive
deficits have on treatment efficacy nor do they employ cognitive rehabilitation treatment strategies to remediate identified
cognitive deficits. Few studies exist that investigate the remediability of neurobehavioral deficits or the efficacy of integrating
cognitive rehabilitation strategies into more traditional treatment programs. Empirical investigations conducted to date indicate
that some cognitive deficiencies secondary to alcoholism are amenable to cognitive rehabilitation and this remediation is
generalizable. Rigorous well-controlled treatment outcome investigations are needed in order to determine the efficacy of
cognitive rehabilitation techniques in naturalistic settings using ecological outcome measures. Also, emphasis should be placed
on integrating cognitive rehabilitation techniques with proven efficacy into traditional alcoholism treatment programs. 相似文献
