Is perseveration caused by inhibition failure? Evidence from preschool children's inferences about word meanings

Four studies examined the relation between children's cognitive inhibition and flexibility in a lexical inference task. Children's linguistic flexibility was assessed by the Flexible Induction of Meaning (FIM) test (Deák, 2000a), which requires that children shift inferences about the meanings of several words for novel objects. In Study 1, 54 3-year-olds either were trained between blocks of problems, for a delay of 3 min, or received no training or delay. Training delays did not influence perseveration. In Study 2 (N=72 3- and 4-year-olds') novel word problems were grouped either to increase the frequency of cue switches (i.e., reduce response "set") or minimize the interval between problems about the same objects. Again, no effect was found. In Study 3, 48 3- and 4-year-olds completed 6 preliminary trials; in a high interference group these trials generated a response set to be inhibited upon the first switch to a new cue context. This group did not perseverate more than a control group. There was no association between FIM perseveration and a Stroop-like test of verbal inhibition though both were marginally related to receptive vocabulary. In study 4 (48 3- and 4-year-olds), FIM was again unrelated to Stroop performance, but was related to the ability to tell whether a situation or problem is indeterminate. Thus, flexibility across semantic inferences is not influenced by timing, order, and number of pre-switch problems and is not predicted by individual differences in a test of verbal inhibition. However previously reported age and individual differences in flexible induction of word meanings are robust and related to vocabulary and logical ability.     

“What Button Do I Press?” the Consequences of Conducting a Service Learning Project with Senior Citizens

In an effort to build interest in the two-year old service learning center and to fulfill its mission to integrate academic life with service in thoughtful and relevant ways, a competition was held to award developmental grants to faculty to create innovative courses incorporating service learning. The winning proposal from the business school used a business ethics course as the vehicle for formally introducing service into the business curriculum. This paper will tell the story of the intended and unintended consequences of building collaboration on several levels: between generations, between college and community, between faculty and college resources, between student teams, and between theory and practice.

A Review Of Geraldine Jonçich's The Sane Positivist: A Biography Of Edward L. Thorndike

This book review, unfinished at the author's death, examines in historical context Thorndike's law of effect, his Animal Intelligence monograph of 1898, and related works on learning and behavior.     

Thorndike's Puzzle Boxes And The Origins Of The Experimental Analysis Of Behavior

The year of Thorndike's dissertation on animal intelligence, 1898, may mark the beginning of the field that eventually became known as the experimental analysis of behavior. The dissertation began a major shift in thinking about animal and human learning, provided important methodological innovations, and carried the seeds of later research and theory, particularly by B. F. Skinner. Although Thorndike was an associationist in 1898, the dissertation began the systematic search for fundamental behavioral processes, and laid the foundation for an empirical science of behavior.     

Personalized System Of Instruction In Cyberspace

Four different undergraduate psychology courses with no allotted classroom time slots were taught in the same term by means of a computer-based version of Keller's personalized system of instruction (PSI), called computer-aided personalized system of instruction (CAPSI). Students' performance and ratings indicate that CAPSI is a viable on-line educational method.     

Facilitation of Sodium Aversion Learning in Sodium-Deprived Rats

Two experiments with rats explored the effects of sodium deprivation induced by furosemide injections upon acquisition of taste aversion to sodium chloride (NaCl). In Experiment 1, rats under either sodium deprivation or a balanced nutrition condition were given access to a limited amount of NaCl solution prior to poisoning. When all rats were tested under sodium repletion, the previously sodium-deprived rats consumed less NaCl than did the nondeprived rats. This finding was replicated in Experiment 2A in which ingestion of a compound solution of NaCl and hydrochloric acid (HCl) was followed by poisoning. Consumption of HCl, however, showed the opposite pattern: the sodium-deprived rats drank more HCl than did the nondeprived rats, a result that was replicated in Experiment 2B. These results suggest that sodium deprivation strengthens the salience of NaCl, thereby facilitating acquisition of aversion to this taste and strongly overshadowing that to a simultaneously presented taste.     

The Neural Basis of Motor-Skill Learning

Recent work indicates that motor-skill learning is supported by four processes: a strategic process that selects new goals of what to change in the environment, a perceptual-motor integration process that adjusts to new relationships between environmental stimuli and the appropriate motor response, a sequencing process that learns sequences of motor acts, and a dynamic process that learns new patterns of muscle activations. These four processes can operate in one of two modes: an unconscious mode, in which one is aware only of the goal of the movement, or a conscious mode, in which one consciously controls detailed aspects of the movement. This article provides an overview of these four processes and two modes, and describes their neural bases.     

表演式学习──表演理论对“最近发展区”的发展

美国当代心理学家、剧作家、表演理论的创始人弗雷德·纽曼（FredNewman）及其同事致力于在实践中发展维果茨基的理论,从表演的维度探讨了zpd的概念,并以此为核心提出了表演式学习的概念,以区别于在当今社会大行其道的工具性学习,即以获取知识和技能为目的的学习。表演理论通过对工具性学习的消极影响的批判及对表演式学习的倡导,在人的教育和发展方面提出了独到见解。     

学前数学教法和儿童智能发展的追踪研究

本研究从儿童心理发展的特点和数学学习之间的内在规律出发,综合考查了各类教学法在学前施教的利弊;同时,在活动教法、指导操作法、演示法和讲授法之间做了对比实验,并设计了一整套以指导操作法为主的学前数学教法,以演示为主的数学教法之间进行了长期、深人的跟踪对比实验。结果表明,在其他变量基本被控制的条件下,指导操作法优于其他的教法;实验班儿童的智能发展,特别是数学能力的发展,明显好于对照班的儿童。这个优势一直持续到小学毕业。
