What are the representations and learning mechanisms that underlie conceptual development? The present research provides evidence in favor of the claim that this process is guided by an early-emerging predisposition to think and learn about abstract kinds. Specifically, three studies (N=192) demonstrated that 4- to 7-year-old children have better…

As they observe or produce events, infants identify variables that help them predict outcomes in each category of events. How do infants identify a new variable? An explanation-based learning (EBL) account suggests three essential steps: (1) observing contrastive outcomes relevant to the variable; (2) discovering the conditions associated with…

A reminding-based generalization view of category learning was studied in 4 experiments involving a total of 247 college students. Experiments demonstrated that categorization by reminding can affect what is learned about the category and later categorization performance. Implications of the results for category learning are discussed. (SLD)

This paper provides experimental demonstration of remindings during learning and examines their effect on performance, as well as effects of practice and difficulty. Three experiments examining the occurrence, effects, and conditions of remindings are presented, and the implications for theories of cognitive skill learning are discussed.…

P. Lewicki and others (1988) suggested that subjects unconsciously abstract tacit knowledge about a complex pattern of events in a situation that departs from the artificial grammar learning pattern. The present experiment with 40 third year university students offers an alternative framework that does not assume unconscious rule abstraction. (SLD)

The standard approach guiding research on the relationship between categories and causality views categories as reflecting causal relations in the world. We provide evidence that the opposite direction also holds: categories that have been acquired in previous learning contexts may influence subsequent causal learning. In three experiments we show…

Empirical parallels between repetition priming (RP) and automaticity predicted by the instance theory were studied in 4 experiments with a total of 196 introductory psychology students. RP was viewed as the first few steps toward automaticity. Characteristics RP shares with automaticity, beyond a general speed-up with practice, are discussed. (SLD)

This article explores the use of structure in the encoding and retrieval of music and its relation to level of skill. Twenty-two pianists, classified into four levels of skill, were asked to learn and memorize an assigned composition by J. S. Bach (different for each level). All practice was recorded on cassette tape. At the end of the learning…

Four experiments investigated the attentional requirements of learning as assessed by a serial reaction time task. The effects of a dual-task condition, plus the responses of memory disorder patients, were also investigated. The relationship between learning and awareness, preserved learning in amnesia, and the separateness of memory systems are…

Four experiments with college undergraduates examine interactions between linearly separable and nonlinearly separable abstract category structures, different knowledge types, and instructions on classification learning tasks. Implications for independent cue models and interactive cue models are discussed. (LMO)

Three experiments using college students examine the processes involved in deductive reasoning. Effects of training in classroom and laboratory situations confirmed the authors' hypothesis that people use pragmatic reasoning schemas rather than syntactics rules of logic for problem solving. Training materials used in experiments 1 and 3 are…

Two experiments, with 300 adult women as subjects, studied the effects of laboratory training on the use of the Conjunction Rule, a principle of probability that is often violated. Learning alternative strategies enabled trained subjects to use extensional reasoning rather than intensional heuristics. (SLD)

In earlier work we have shown that adults, young children, and infants are capable of computing transitional probabilities among adjacent syllables in rapidly presented streams of speech, and of using these statistics to group adjacent syllables into word-like units. In the present experiments we ask whether adult learners are also capable of such…

Two experiments investigated learners' procedures in acquiring knowledge from maps. The better learners used successful techniques for encoding spatial information, evaluating their progress, focusing attention on unlearned information, and partitioning the map by spatial region or concept. Visual memory ability was also important. (Author/GDC)

Mismatch between gesture and speech was used to study cognitive processes that characterize the transition between incorrect, but rule-governed, problem understanding to correct rule-governed understanding among 90 fourth graders in Chicago (Illinois). Data support the idea that the transitional state is characterized by concurrent activation of…
