Three pigeons were trained on oddity matching in which either 1, 4, 8, 16, or 32 sample-key observing responses were required to turn off the sample stimuli and turn on the comparison stimuli. Oddity accuracy increased when the observing-response requirement was raised and decreased when the requirement was lowered. Next, while the observing requirement was maintained at one response, the number of responses required to the comparison stimuli was either 1, 4, 8, 16, or 32. Under these conditions, choice was defined as the comparison that first accumulated the required number of responses. In general, increasing the comparison-response requirement decreased accuracy and lowering the comparison requirement increased accuracy. The fixed-ratio observing requirements appeared to facilitate control by stimuli serving an instructional function.  相似文献

Eight naive rats were reared in enriched or impoverished environments for 39 days after weaning and then lived in operant chambers, in which they could obtain food pellets freely or by lever pressing, for 25 or 30 days. The animals raised in an impoverished environment acquired the bar-press response quickly when placed in the operant chambers and maintained a preference for obtaining food via bar pressing. Animals raised in an enriched environment did not learn to lever press, as demonstrated by low levels of responding and the lack of bar pressing when free food was subsequently removed. It was concluded that restricting animals' postweaning environments facilitated learning in a choice situation, probably because of increased activity levels. The results are interpreted in relation to previous studies on rearing environments and on contrafreeloading.  相似文献

"八荣八耻"的道德哲学   总被引:2,自引:0,他引:2  
宋希仁 《伦理学研究》2007,(1):19-23,33
“八荣八耻”的社会主义荣辱观,把社会主义道德的要求聚焦到荣辱观,集中点击人的良心,可谓四两拨千斤;“八荣八耻”督促人们作出善恶选择,启迪了个人的道德自觉、自主和自律,同时也强调了公民的道德权利和义务;“八荣八耻”的落实重在修养和践行,为社会主义道德建设与和谐社会的构建创造了精神条件。  相似文献

资源保存理论(conservation of resources theory, COR)是组织行为学研究近30年中被引最高的理论之一。COR的提出源自Hobfoll对临床应激障碍的观察与思考,历经了多次修订后该理论逐步由一个压力–反应模型发展成了一个以个体资源存量及其动态变化解释行为动因的动机理论,形成了一个具有较广泛外延的理论体系。组织行为学是资源保存理论标志性文献的施引文献的核心来源。大量组织行为学研究对COR中的资源损失漩涡、获得螺旋等核心过程进行了实证检验,涉及广泛的研究议题,使COR成为了理解员工心理与行为动因的最具影响力的理论之一。COR在组织行为学中的应用面临一定的挑战,其中有来自认知评价理论、适应理论的观点挑战,也有其作为一个"跨界理论"带来的挑战。组织行为学研究在应用COR时应充分尊重其理论要义,避免削足适履。  相似文献

电子地图汉字大小辨认阈限和合理字间距   总被引:1,自引:1,他引:1  
本研究由三个实验组成,探讨电子地图中汉字呈现的辨认闽限和合理字间距(信息载负量)问题。实验一采用恒定刺激法测定电子地图中汉字的辨认闽限,结果显示,汉字复杂度和背景的复杂度都影响地图汉字识别,且不存在交互作用;宋体汉字的平均辨认阈限为7.0771’。实验二运用调整法测得在电子地图中宋体汉字的舒适阈限(能识别每个笔画的汉字辨认阈限)为16.6951’。实验三以视觉搜索方法研究字间距(体现在电子地图中单位面积字数)与搜索效率的关系,结果显示,每个汉字平均耗费的搜索时间随着字数增加而减少,说明字数越多,搜索效率越高。  相似文献

主动性人格与工作绩效:个体-组织匹配的调节作用   总被引:4,自引:0,他引:4  
温瑶  甘怡群 《应用心理学》2008,14(2):118-128
本研究的目的:考察主动性人格在中国企业内对工作绩效的预测性及个体-组织匹配在其中的调节作用。方法:研究以三家中国本土企业的253名员工为被试,使用修订过的主动性人格量表。结果:(1)除了大五人格和社会赞许性之外,主动性人格还可以解释工作绩效8.5%的方差变异;(2)整体分析时只有团队导向因素显著,单独分析时高新独资企业中注重细节因素、团队导向因素和结果导向因素有显著的调节作用;民营企业中尊重员工因素有显著的调节作用;国有企业中革新性因素和团队导向因素有显著的调节作用。结论:主动性人格可以有效地预测工作绩效,个体-组织匹配则根据不同的企业组织,不同的因素在主动性人格和工作绩效的关系中起调节作用。关于本研究的贡献与不足以及未来的研究方向都有所讨论。  相似文献

Aggression is defined as generic assertiveness which includes both constructive and destructive behaviors. An attempt is then made to classify the distinctive operational settings (phenotypic situations) which trigger aggression. The classes of such settings are: 1) privation - the frustration of vital needs and the frustration due to inner conflict of needs; 2) conflict (social) - situation-specific competition and intragroup rivalry for dominance; and 3) victimization — predator-prey relations and vandalism per se. Critical questions which emerge from the definition and classification are posed.  相似文献

In this study the eco-cultural model of parenting (Keller, H. (2007). Cultures of infancy. Mahwah, NJ: Erlbaum) was applied to the study of joint attention behavior of children from families with different socio-economic status (SES). It was hypothesized that infants’ early communication styles would differ with SES reflecting more independent or interdependent interactions with their caregivers. It was also hypothesized that infants would use the same types of behaviors whether they have declarative or imperative communication goals. The Early Social Communication Scales (ESCS, Mundy et al., 2003) was administered to 103 typically developing infants of 12 months (approximately half of them siblings of children with autism). A factor analysis, yielding four behavioral factors, namely pointing, eye contact, actions and following points, confirmed the hypothesis that infants use behaviors consistently across situations independent of their communicative intent. MANOVAs (comprising parental education and income) revealed that higher SES infants showed actions more frequently in the ESCS whereas lower SES infants followed experimenter's points more frequently. The results are discussed in the context of presumably differing socialization goals for infants and the divergent contribution of parental education and income that seem to have additive contribution to some factors (actions, following points) but divergent contributions to others (pointing, eye contact).  相似文献

Following a rise in the life expectancy of cystic fibrosis (CF) patients, many adults with CF form couple relationships. Yet, dyadic coping has not been previously examined in people with CF. This study examined how adults with CF and their partners cope as a couple with the illness, and what meanings each partner and the couple as a unit attribute to the experience. Seventeen adult CF patients and their partners participated in separate semi‐structured in‐depth interviews. Two main patterns of dyadic coping with CF were identified as follows: cooperation and tension. For couples in cooperation, the marital relationship served as a resource for adaptive coping. These couples were characterized by similarities in their perception of the place of CF in their lives and of their roles in the marital relationship. Couples in tension described the couple relationship as strained by difficulty of accepting the disease, proliferation of negative emotions, and a sense of burden and loneliness in the process of coping. Findings point to the importance of mutual empathy, clear and accepted division of roles between the partners, and open communication for facilitating coping as a couple.  相似文献
