Various demonstrations of “time stamp” effects in the animal learning literature have reinforced the idea that circadian information is encoded as part of a combined internal/external representation of context and that this contextual information is utilized for complex retrieval processes supporting memory. The goal of the present series of experiments is to assess this idea by manipulating training/testing circadian times on a battery of learning and memory tasks commonly used in the rodent. The data obtained from five experiments using four different learning and memory paradigms provide no evidence for “time stamp” effects on place memory, context memory (aversive or appetitive), or S-R habit learning.  相似文献

Behavior is a property of living animals and is therefore a biological phenomenon. This book shows us what it looks like to have a truly biological science of behavior. Such a science needs to discover the laws that control behavior as it is occurring, and it is this that behavior analysts and other psychologists interested in animal behavior and learning have done so well. The science also needs to explain, however, the role that behavior plays in the life of the individual and in the existence of the species, and this has not been part of the agenda for most psychologists. Shettleworth addresses all of these questions about behavior. She views learning in terms of what it accomplishes for the individual and then provides insight into its causal laws and its evolution. All of this is accomplished with a critical eye and unremitting rigor. These accomplishments occur in the context of a theory based on a unique combination of domain‐general and domain‐specific processes that takes a major step in the direction of showing what students of animal behavior and animal learning have to offer each other.  相似文献

学习不良儿童社会信息加工的特点   总被引:15,自引:1,他引:14  
设置儿童与同伴、成人相互作用的三类情景,每类情景又分为模糊情景和清晰情景两种情况,通过对51名小学生进行结构性访谈,比较了学习不良儿童与一般儿童在信息加工各阶段的差异。结果发现,无论是模糊情景还是意义清晰情景,学习不良儿童和一般儿童在对权威社会情景进行编码时存在显著差异,学习不良儿童的编码准确性和全面性显著低于一般儿童;在模糊同伴情景下,学习不良儿童的反应数量显著多于一般儿童,其消极或侵犯性的反应也多于一般儿童。  相似文献

We address the problem of predicting how people will spontaneously divide into groups a set of novel items. This is a process akin to perceptual organization. We therefore employ the simplicity principle from perceptual organization to propose a simplicity model of unconstrained spontaneous grouping. The simplicity model predicts that people would prefer the categories for a set of novel items that provide the simplest encoding of these items. Classification predictions are derived from the model without information either about the number of categories sought or information about the distributional properties of the objects to be classified. These features of the simplicity model distinguish it from other models in unsupervised categorization (where, for example, the number of categories sought is determined via a free parameter), and we discuss how these computational differences are related to differences in modeling objectives. The predictions of the simplicity model are validated in four experiments. We also discuss the significance of simplicity in cognitive modeling more generally.  相似文献

Grey parrots ( Psittacus erithacus ) solve various cognitive tasks and acquire and use English speech in ways that often resemble those of very young children. Given that the psittacine brain is organized very differently from that of mammals, these results have intriguing implications for the study and evolution of vocal learning, communication, and cognition.  相似文献

易学的推类逻辑   总被引:1,自引:0,他引:1  
易学中的逻辑问题,是一个在易学和逻辑学研究中被忽视的问题,但又是一个关系到对中国文化史、思想史和逻辑史的再认识的重要问题。易学中的逻辑是推类逻辑,本文给出了理由,同时以现代逻辑的方法给出了易学推类逻辑的形式系统,并作了讨论。指出易学逻辑是在中国文化背景下的以汉字表述的特有逻辑形式,建立了中国古代的普遍语言,形成了自我满足的语义系统,其在为人们提供正确的认识方法和为古代科学提供认识工具方面与西方逻辑是一致的。  相似文献

We designed this study to examine children's self-reported and observed emotional and behavioral responding to marital conflict as a potential mechanism linking marital physical aggression (as reported by the parents) and children's behavioral adjustment (as reported by their preschool teachers). In a sample of 48 preschoolers, parental marital physical aggression was positively associated with children's observed dysregulated responding to interparental conflict and negatively associated with children's self-reported behavioral disruption. Marital aggression and children's self-reported responding to marital conflict predicted teacher-reported behavior problems, with both variables adding unique variance. Our findings suggested a potential pathway linking exposure to marital conflict, children's regulatory strategies, and children's behavioral adjustment outside the home.  相似文献

This study was undertaken in an effort to sharpen selection procedures and improve faculty response to the learning needs of students. Eschewing a traditional anticipatory approach in determining suitability for training, the authors undertook a retrospective study to investigate the learning trajectories of candidates. A learning trajectory is defined as the particular way individuals learn, or fail to learn, as they advance through an Institute's training program. The database of this study grew out of the authors' experience with students in classrooms, in supervision, and from discussions about them in Progression, Selection, and The Evaluation of Learning committees. Realizing the reductionism of categorizing a highly complex and diverse group of individuals, the authors, nonetheless, found that candidates tended to group into five rather distinct categories. This paper discusses in detail the characteristics of these five categories and suggests ways in which this grouping may help in both selection and in planning more effective training for candidates. The authors are fully aware that this study has impressionistic qualities and warrants more rigorous research methods, but hope that it will arouse interest in other psychoanalytic centers and stimulate studies to corroborate, refine, or reject the conclusions reached by this group.  相似文献

基于行为的绩效评定方法的研究进展   总被引:20,自引:2,他引:18  
从20世纪60年代至今,基于行为的绩效评定一直是各类组织的主要绩效评定方法。基于工作结果的非判断性绩效测量有其难以克服的局限,各种基于工作行为的判断性绩效测量方法相继开发出来。行为指标的筛选成为研究的主要问题之一。组织公民行为、区分作业绩效与关系绩效等研究,向基于行为的绩效评定提出了新的问题。  相似文献
