Data representing high, medium, and low response rates in constant and nonconstant patterns were generated by electromechanical equipment to determine whether the same data collected by time-sampling, interval recording, and frequency recording would be represented similarly by each method. Results indicated: (1) that time-sampling provided an extremely inaccurate estimate of responding, and (2) that interval recording accurately represented responding of low and medium rates, but grossly underestimated high-rate responding. 相似文献

Failure to share household chores equitably may be a major cause of the high failure rate of experimental group-living arrangements. A behavioral approach to worksharing based on a point system was implemented in one experimental group and its most important components experimentally evaluated. Experiment I showed that awarding credits produced more work than not awarding credits. Experiment II showed that making credits contingent on the outcome of a detailed inspection produced more work than awarding credits noncontingently. Experiment III demonstrated that awarding rent reductions contingent on credit earnings produced more work than awarding rent reductions noncontingently. Other evaluative data suggest that the resulting living arrangement is cheaper, more effective, and more satisfactory to the residents when compared to the most popular alternative living arrangements. 相似文献

Behavioral contrast as a function of the temporal location of reinforcement 总被引:2,自引:2,他引:0 下载免费PDF全文
Williams BA 《Journal of the experimental analysis of behavior》1976,26(1):57-64
Pigeons were trained on a multiple variable-interval variable-interval schedule of reinforcement. One component was then changed to a variation of a fixed-interval schedule in which the same rate of reinforcement was obtained as previously but the location of the reinforcer was fixed within the component. The effects of different temporal locations were compared. An increase in response rate for the unchanged variable-interval component (behavioral contrast) occurred when the reinforcer was located in the middle or at the end of the FI component, but response suppression occurred when it was located at the beginning of the component. The pattern of results cannot be explained by any previous theories of contrast. The overall response rates, and the pattern of local rates within the components, were consistent with the hypothesis that the major determinant of the contrast effect was the transition to a lower reinforcement rate following the unchanged component. 相似文献

Interactions in multiple schedules: the role of the stimulus-reinforcer contingency 总被引:4,自引:4,他引:0 下载免费PDF全文
Spealman RD 《Journal of the experimental analysis of behavior》1976,26(1):79-93
In Experiments I and II, pigeons were exposed to single-key multiple schedules of response-independent and -dependent food presentation. Components were correlated with different keylights. When the rate of food presentation in the first component exceeded that in the second component, the local rate of key pecking was relatively high at onset of the first component. Overall rate in that component varied inversely with component duration and the rate of food presentation in the second component. When responding was maintained in the second component, the local rate of key pecking was relatively low at onset of that component. Overall rate in the second component varied directly with component duration and the rate of food presentation in that component. In Experiment III, pigeons were exposed to a two-key multiple schedule. Pecks on a constantly illuminated key produced food. Components were correlated with the color of a second key on which pecks had no scheduled consequences. The effects of component duration and rate of food presentation under the single-key response-dependent schedule were synthesized by combining response rates on each concurrently available key under the two-key procedure. The results support an account of multiple-schedule interactions in terms of the joint influence on responding of stimulus-reinforcer and response-reinforcer contingencies. 相似文献

自尊与人际互动:理论、研究与问题 总被引:1,自引:0,他引:1
基于自我确认理论开展的大量研究,有助于理解自尊对人际互动行为的调节作用。然而,研究者对自尊的测量工具不尽相同,筛选实验被试的标准也不尽一致,实验范式忽略了对实际人际互动情境的操纵,单纯采用人际选择反应作为测量自我确认的指标,因而难以形成具有整合性的理论模型。今后的研究有必要在编制合适的测量工具的基础上,将整体自尊与特殊自尊作为两个独立的变量置于整合性实验范式下开展研究,同时采用对人际评价信息的认知判断和对评价者的交往选择的双维指标,以全面揭示整体自尊与特殊自尊对自我确认过程的相对作用及其心理机制。 相似文献

The present study investigates the impact of first language (L1) structural frequency and L1 lexical accessibility, manipulated via cognate status, on second language (L2) speech production. L1 German–L2 English speakers and L1 English speakers completed a production task containing pre- and post-modified possessive noun phrase (NP) constructions (e.g. The actress’s sofa vs. The sofa of the actress) in which the head nouns were English-German cognates (e.g. sofa) or noncognates. While English prefers pre-modified NPs, German has a strong frequency bias for post-modified NPs. L2 English speakers exhibited higher production accuracy than L1 English speakers on post-modified NP sentences. However, facilitative L1 effects in production latencies were restricted to post-modified NP sentences containing cognates and only developed cumulatively after repeated exposure to post-modified NP sentences. We discuss how cognate status and L1 structural frequency differentially influence the accuracy and timing of choosing between different structural alternatives during L2 production. 相似文献

Out of 228 Iranian preschool Martyrs' children whose behaviour adjustment in the nursery settings was screened using the Preschool Behaviour Checklist, 12 well adjusted, zero scorers were compared with 8 poorly adjusted, high scorers. Using the parent's Behaviour Checklist, high scorers showed significantly more problems at home than zero scorers. On the Malaise Inventory, mothers of high scorers showed poorer mental health than mothers of zero scorers. Home observations showed that mother-child interaction was more aversive in high scorers than in zero scorers. More mothers of zero scorers had remarried. 相似文献

儿童社会观点采择的发展及其与同伴互动关系的研究 总被引:28,自引:0,他引:28
采用经过标准化处理的观点采择故事对幼儿园大班和小学二、四、六年级儿童的社会观点采择能力进行测量,利用录像观察技术和同伴评定法分别测定幼儿园大班和小学儿童的同伴社会互动经验,考察儿童社会观点采择的发展及其与同伴互动经验之间的关系。研究发现:(1)幼儿园大班儿童在准确采择他人观点方面还存在较大困难,6-10岁为儿童社会观点采择能力快速发展的时期,10岁左右的小学儿童能够根据有关事件信息准确推断他人的观 相似文献
