This study examined the interaction within and between 20 intact families. As in past research, when parents were separated and not influenced by their child (i.e., completing a toy desirability scale), traditional findings were supported; neutral toys are not specific to the gender of the child while feminine toys were preferred for girls and masculine toys were preferred for boys. However, when parents were actively engaged in play with their child this traditional pattern was not supported. In general, parents spent the least amount of time with feminine toys. Children eagerly accepted most of the toys presented by their parents and their enthusiasm was equal for the toys in all three categories. This research suggests a change in parents' perceptions of what is acceptable gender-typing behavior.  相似文献

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.  相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.  相似文献

One Personality, Multiple Selves: Integrating Personality and Social Roles   总被引:1,自引:0,他引:1  
ABSTRACT How do people maintain multiple, role-specific self-conceptions as well as a consistent sense of self? In a sample of middle-aged women, we examined three issues: (a) the ways in which people view themselves as both different and similar across social roles (e.g., parent, friend, worker), (b) how role-specific self-conceptions and general self-conceptions are related, and (c) the merits of predicting role-specific criteria from role-specific and general self-conceptions. Results showed that subjects' self-conceptions were specific to role contexts, yet highly correlated across those same role contexts. In addition, role-specific self-conceptions were more similar to the general self-concept for roles with which the individual was more satisfied. Finally, as predicted from the bandwidth-fidelity trade-off, ratings of the general self correlated moderately with outcomes across all role domains, whereas ratings of role-specific self-conceptions correlated strongly with outcomes for the same role, but not in other roles.  相似文献

The Emergency Psychiatry Nursing Assessment Report Framework (EP Nurse) is designed to guide the nurse through the interview-and-reporting process, and to produce a report of the nursing evaluation in emergency psychiatry in 5–10 min. Input includes identifying information, presenting complaints, substance-use history, medical history and vitals, psychiatric medications, treatment history, history of mental illness, last hospitalization, family history of mental illness, nursing diagnosis, and nursing intervention. EP Nurse is intended to be used by licensed nurses familiar with nursing assessment in emergency psychiatry. It is suitable for adult patients.  相似文献

Eighty-two per cent of all cases of abuse or neglect of an adult with mental retardation substantiated by the Abuse Investigation Division of the Connecticut Office of Protection and Advocacy for Persons with Disabilities over a five-year period occurred in the victim's residence. Chi square analyses revealed that there was significantly more abuse in institutions and group homes and significantly less in the individual's own home. Furthermore, analyses revealed that there was significantly more personal neglect in group homes and community training homes and significantly less in own homes. The results were discussed and recommendations made regarding ways of reducing abuse and neglect.  相似文献

Relatives (N=121) of adult schizophrenia patients were interviewed to investigate predictors of their level of psychological distress and of rejecting attitudes toward the sufferer. The relatives' total stress, particularly that associated with poor communication skills in the sufferer, predicted several measures of their psychological distress, and the same variables plus turbulence of sufferer behavior (i.e., violence and disruptiveness) predicted rejection of the sufferer by the relative. In each case, adequacy of family support moderated the influence of the stressors, although this effect was more marked for distress outcomes than for rejection. The results have important implications for the sorts of professional and peer support which relatives may need to encourage their performance of this potentially burdensome role. In addition, the results fit a classic stress management model and provide a feasible alternative to the Expressed Emotion Model of the relationship between relatives' rejection and patients' illness severity.  相似文献

Recent experiments have indicated that contrast effects can be obtained with vowels by anchoring a test series with one of the endpoint vowels. These contextual effects cannot be attributed to feature detector fatigue or to the induction of an overt response bias. In the present studies, anchored ABX discrimination functions and signal detection analyses of identification data (before and after anchoring) for an [i]-[I] vowel series were used to demonstrate that [i] and [I] anchoring produce contrast effects by affecting different perceptual mechanisms. The effects of [i] anchoring were to increase within-[i] category sensitivity, while [I] anchoring shifted criterion placements. When vowels were placed in CVC syllables to reduce available auditory memory, there was a significant decrease in the size of the [I]-anchor contrast effects. The magnitude of the [i]-anchor effect was unaffected by the reduction in vowel information available in auditory memory. These results suggest that [i] and [I] anchors affect mechanisms at different levels of processing. The [i] anchoring results may reflect normalization processes in speech perception that operate at an early level of perceptual processing, while the [I] anchoring results represent changes in response criterion mediated by auditory memory for vowel information.  相似文献
