This study examined the impact of nonsexist curricula and teacher's sex on children's sex role learning. Thirty-two boys and 32 girls, aged three to five, were equally divided among four programs: nonsexist curriculum, female director; nonsexist curriculum, male director; control curriculum, female director; and control curriculum, male director. Sex role discrimination and preference were measured at the beginning and end of a six-month period. Exposure to the nonsexist curriculum produced significantly greater reductions in sex stereotyping on all measures than exposure to the control curriculum. Moreover, children in the male-directed nonsexist program displayed greater decreases in stereotypic knowledge and preference for sex-typed children's activities than those in the female-directed nonsexist program, while children in the male-directed control program showed more stereotypic increases on these measures than their counterparts in the female-directed control program. Finally, children under the direction of an opposite-sex teacher exhibited less stereotypic changes in preference for adult activities than children under the direction of a same-sex teacher. Implications for early childhood programs are discussed.This research was partially supported by an Oregon State University Foundation grant from the Shell Foundation and a grant from the Milne Computer Center.  相似文献

Summary This article considers the study reported by Rossmann (1983) in which a failure to replicate the findings of Parkin, Lewinsohn and Folkard (1982) is reported. It is argued that Rossmann's findings could be attributed to methodological differences and, as such, do not constitute a replication failure. Guidelines for further replication attempts are offered.  相似文献

The ability of 5-month-old infants to recall temporal information and utilize temporal organization was investigated in two experiments. Infants were trained to fixate a hierarchically structured or an unstructured sequence of stimuli which appeared in four spatial positions. In the first study, the number of infants who demonstrated correct recall through the third serial position of a sequence was significantly better then would occur by chance. In the second study, infants given structured sequences showed a significant increase in the number of correct fixations across trials, and they recalled across serial positions better in structured sequences. Also, accuracy of recall in both studies for the middle serial positions was related to hierarchical organization following 8-unit structured sequence training but was at chance level following unstructured sequence training. Results of both studies were interpreted within a temporal organizational framework: Infants appear to utilize organization within sequences of information.  相似文献

The history of the growth of interest in child abuse in the Western World over the last two decades is described chronologically. Problems of definition of a phenomenon which is a deviation from social norms are discussed, including the problem of distinguishing acceptable discipline from abuse. The literature on parent-training approaches to the treatment of abusive parents is reviewed. It is argued that researchers in the U.S.A. and the U.K. are working within different statutory frameworks, from different definitional criteria and with different conceptualizations of successful outcome. The need for multiple outcome measures, in terms of quality of life for the abused child, and for long-term follow-up is stressed, together with the importance of clinical experience in the planning and execution of evaluative treatment research.  相似文献

The present paper focuses on children's beliefs about sex differences and how these are related to age and gender. Seven, ten, and fifteen year olds (N=427) were asked to give explanations for their beliefs about sex differences. In strong agreement with previous research and the cognitive-developmental theoretical framework, marked age differences were found: younger children were more likely than older children to emphasize biological and physical factors. Significant gender differences were also found, especially for 15 year olds. Girls were much more likely to attribute sex differences to social factors, and boys to biological factors. These gender differences were interpreted as being indicative of different life experiences of males and females, with females being more likely to have experienced conflicts between their own values about sex-role behavior and those of society. Findings were also interpreted as being consistent with the recent emphasis on gender schema. Nevertheless, it was argued that theories of gender schema need to take more account of content—of the beliefs that people hold about sex roles—and, in particular, that more attention be given to exploring gender differences in beliefs.  相似文献

The present study examined 8-12-year-old children's perceptions of parents' responses to sons and daughters experiencing interpersonal conflicts. In general, the children expected parents to respond in a manner consistent with traditional instrumental-expressive sex-role stereotypes. The implication of these findings for inadequacies in the socialization of interpersonal problem-solving styles in boys and girls is discussed.  相似文献

The influence of contextual stimuli on the conditioning and performance of responding to a discrete stimulus was examined in the US preexposure paradigm using both context shift manipulations and a measure of context conditioning. Four groups of rats received both repeated exposure to an electric shock US in one context (Context 1), and repeated nonshocked exposure to a second context (Context 2). Two additional groups of rats received exposure to these contexts, but never received shock presentations. Rats exposed to shock learned to escape from the stimuli of Context 1, but did not escape from the stimuli provided by Context 2. Rats not exposed to shock failed to escape from either context. All rats then received a single CER conditioning session in which four pairings of a 3-min noise CS and shock US were presented. Half the rats received those CS-US pairings in the excitatory Context 1, while the remaining rats received those pairings in the neutral Context 2. Finally, half the rats in each of the CER conditioning treatments received extinction test trials of the noise CS in Context 1, while the remaining rats received those test trials in Context 2. Thus, this design factorially manipulated the presence of excitatory or neutral contextual stimuli during both conditioning and testing of a discrete CS. In comparison with the two groups of rats never preexposed to shock alone, attenuation in acquisition of conditioned suppression observed during test trials occurred only when CER conditioning had been administered in the excitatory Context 1, and this effect was manifested when testing occurred in either the excitatory Context 1 or the neutral Context 2. These results support the model of R. A. Rescorla and A. R. Wagner (1972) (in A. H. Black & W. F. Prokasy (Eds.) Classical Conditioning II, pp. 64–99, New York: Appleton-Century-Crofts) which asserts that contextual stimuli and sicrete CSs compete for limited associative strength supportable by a given US.  相似文献

We examined articles with experiments published in the Journal of Applied Behavior Analysis and in Behavior Analysis in Practice from 2017 through 2021 to determine how frequently procedural fidelity was assessed. When procedural fidelity was assessed, we determined how often a measure of interobserver agreement for those fidelity data was provided. We also determined how often a measure of interobserver agreement for participants' behavior was provided. Across both journals and all years, 54.7% of relevant articles provided a measure of procedural fidelity. Of them, 17.7% provided a measure of interobserver agreement for procedural fidelity. In marked contrast, 96.4% provided interobserver agreement data for participants' behavior. It is unfortunate that applied behavior analysts frequently fail to provide procedural fidelity data and, when they do, often fail to provide interobserver agreement data for the fidelity data. Reviewers for, and editors of, behavior-analytic journals are encouraged to strongly consider the relative value of procedural fidelity and agreement on procedural fidelity measures when rendering recommendations on the suitability of a given submission.  相似文献

This article focuses on understanding and working with patients who have poorly developed symbolic capacity, or for whom symbolic capacity has been disrupted due to trauma, particularly as it pertains to the use of reverie and interpretation in the analytic process. Many patients who present for Jungian analysis will initially present with deficits in symbolic functioning. This situation results in necessary limitations or modifications in utilizing traditional Jungian techniques such as dream analysis, active imagination, sand tray and other expressive art techniques. The initial phase of analytic work with these patients requires a focus on developing their symbolic capacity before traditional Jungian techniques can be utilized effectively. During the paper Jung's concept of ‘the symbolic attitude’ will be examined as well as the conceptual models of Wilfred Bion and other post-Bionians who outline theories and method for cultivating symbolic capacity and reflective functioning in patients for whom these capacities are impaired or poorly developed.  相似文献

American Indian/Alaska Native (AI/AN) communities are disproportionally impacted by the opioid overdose epidemic. There remains a dearth of research evaluating methods for effectively implementing treatments for opioid use disorder (OUD) within these communities. We describe proceedings from a 2-day Collaborative Board (CB) meeting tasked with developing an implementation intervention for AI/AN clinical programs to improve the delivery of medications to treat OUD (MOUD). The CB was comprised of Elders, cultural leaders, providers, individuals with lived experience with OUD, and researchers from over 25 communities, organizations, and academic institutions. Conversations were audio-recorded, transcribed, and coded by two academic researchers with interpretation oversight provided by the CB. These proceedings provided a foundation for ongoing CB work and a frame for developing the program-level implementation intervention using a strength-based and holistic model of OUD recovery and wellbeing. Topics of discussion posed to the CB included engagement and recovery strategies, integration of extended family traditions, and addressing stigma and building trust with providers and clients. Integration of traditional healing practices, ceremonies, and other cultural practices was recommended. The importance of centering AI/AN culture and involving family were highlighted as priorities for the intervention.  相似文献
