A model for response latency in recognition memory is described which is a strength model incorporating the notion of multiple observations and with the additional assumptions that the variance of the strength distributions increase with set size and that the observer attempts to keep his error rate at a constant level over set size. It is shown that the model can, without recourse to particular parameter values, predict a near linear RT set-size function and, since it is a (TSD) model in its decision aspects, can account for errors and hence error latencies in the recognition task. After the model is described, two experiments are performed which test the prediction that correct mean latency is generally shorter than incorrect mean latency. The prediction is confirmed and this feature is discussed in general, the model being compared with that of Juola, Fischler, Wood, and Atkinson (1971) in this respect. Some possible modifications to the latter model are also considered. 相似文献

Effects of an 18-minute videotape promoting nontraditional career choices of 986 eighth-grade and 11th-grade girls and boys from rural and urban schools were examined. Models were women and men in occupations traditionally held by the opposite sex. Posttreatment realistic, investigative, and social interests of the treatment group who viewed the videotape were compared with a control group that received a minimal intervention. There was not a main effect for the brief videotape treatment. Boys in the treatment group expressed significantly higher social interests at posttest than did control group boys. Findings indicate that brief interventions promoting nontraditional careers have limited impact. 相似文献

本研究探讨儿童对年龄认知发展的过程和特点。主要结果表明:(1)在呈现刺激数量相等的条件下学前儿童对年龄时序相对可变性的认知成绩低于对相对固定性的认知,对前者的认知表现出学龄前、学龄后两个明显的发发阶段;(2)学前儿童对出生次序的认知成绩低于对年龄大小的认知成绩;(3)儿童对年龄将来时的认知表现出由近及远、由短及长的发展趋向。 相似文献

Marriage is embedded in the web of spouses' broader social ties, and relationship quality with parents and parents-in-law is associated with marital quality. Guided by Family Systems theory and using three waves of dyadic data from 268 Chinese different-sex couples across the first several years of marriage, we first conducted a Random-Intercept Actor-Partner Interdependence Cross-lagged Panel Model (RI-APIM-CLPM) to examine the within-family longitudinal associations among husbands' and wives' relationship quality with parents, parents-in-law, and spouse. Then, husbands' and wives' filial obligations were added as predictors of between-family differences in their own and their partner's relationship quality in the three social ties. Among husbands, increased relationship quality in one social tie (e.g., with parents) predicted reductions in relationship quality in the other social ties (e.g., relationships with parents-in-law and marital quality). Our examination of between-family differences demonstrated that high levels of filial obligations predicted higher intergenerational relationship quality and marital quality. By simultaneously considering the within-family associations of multiple social ties and how filial obligations account for between-family differences in relationship quality, we contribute to a nuanced understanding of how Chinese couples' romantic partnerships are embedded in their broader family system. 相似文献

学前儿童“朴素生物学理论”发展的实验研究──对“生长”现象的认知发展 总被引:9,自引:0,他引:9
从学前儿童对生物生长现象的认知入手探查了学前儿童朴素生物学理论的发展,探查了发展中的个别差异和个体内部差异。研究发现:(1)学前儿童在生长维度上逐渐形成了朴素生物学理论;(2)不同教育条件下的儿童对生长的认知存在差异;学前早期儿童的认知成绩更多地受实验任务变式的影响,而学前晚期儿童的个体内部差异则较小。 相似文献

This prospective study of 27 older adults, residing in long-term care facilities, examined the effects of reducing neuroleptic medications to the point of controlling symptoms and reducing side effects. Schizophrenia is a challenging health care condition that leads to delusions, hallucinations, disorganized speech, and a host of other symptoms. Unfortunately, medications control many of the symptoms but cause unwanted side effects unless monitored closely and regulated to each person's needs. This study addresses six research questions related to the reduction of neuroleptic medications. Study findings related to neuroleptic medication dose reduction were encouraging. Additionally, the findings strongly suggest that health care providers working with older adults with the diagnosis of schizophrenia would benefit from planned educational programs about behavior, observations, and medications. 相似文献

12岁儿童充分条件假言推理能力发展的个体差异研究 总被引:8,自引:0,他引:8
以三类不同题目(与生活经验密切联系、与生活经验相悖、与生活经验“脱离”),探查了12岁普通儿童与数学成绩优异儿童充分条件假言推理能力发展的个体差异。通过对测查成绩的聚类分析,可将被试划分为四种不同的类型,从而显示出同一年龄儿童不同的推理能力发展水平:普通组儿童有关推理能力已有初步发展,但推理过程仍经常受其具体内容的束缚;数学成绩优异组儿童假设思维和演绎推理能力协调发展,“形式”从“内容”的束缚中解放出来,推理思维活动能较好地符合有关逻辑规则。这两组儿童假言推理能力的差异可能跟智能水平有关。 相似文献
