Two rhesus monkeys learned the auditory abstract concept ofsame/different. They were trained with 38 different environmental and natural sounds, which were arranged in different combinations as training progressed. Upon transfer to 138 different novel stimuli, they performed as well (78.8% correct) on the first exposure to the novel stimuli as they did (77.3%) with their training stimuli. The comparatively large set of training sounds, contact with the sound source, and a special fading procedure are thought to have contributed to the monkeys’ being able to learn this concept. Implications for species’ similarities/differences in cognitive processing are discussed. 相似文献

Word learning in children: an examination of fast mapping 总被引:1,自引:0,他引:1
Children may be able to gain at least partial information about the meaning of a word from how it is used in a sentence, what words it is contrasted with, as well as other factors. This strategy, known as fast mapping, may allow the child to quickly hypothesize about the meaning of a word. It is not yet known whether this strategy is available to children in semantic domains other than color. In the first study, 2-, 3-, and 4-year-olds were introduced to a novel color, shape, or texture word by contrasting the new term with a well-known word from that domain. They were then tested for their ability to produce and comprehend the new term and for whether they knew what semantic domain the word referred to. The results show that even 2-year-old children can quickly narrow down the meaning of a word in each of the semantic domains examined, although children learned more about shape terms than color or texture words. A second study explored the effects of several variables on children's ability to infer the meaning of a new term. One finding of this study was that if the context is compelling, children can figure out the meaning of a new word even without hearing an explicit linguistic contrast. 相似文献

Quantity discrimination abilities are seen in a diverse range of species with similarities in performance patterns, suggesting common underlying cognitive mechanisms. However, methodological factors that impact performance make it difficult to draw broad phylogenetic comparisons of numerical cognition across studies. For example, some Old World monkeys selected a higher quantity stimulus more frequently when choosing between inedible (pebbles) than edible (food) stimuli. In Experiment 1 we presented brown capuchin (Cebus [Sapajus] paella) and squirrel monkeys (Saimiri sciureus) with the same two-choice quantity discrimination task in three different stimulus conditions: edible, inedible, and edible replaced (in which choice stimuli were food items that stood in for the same quantity of food items that were given as a reward). Unlike Old World monkeys, capuchins selected the higher quantity stimulus more in the edible condition and squirrel monkeys showed generally poor performance across all stimulus types. Performance patterns suggested that differences in subjective reward value might motivate differences in choice behavior between and within species. In Experiment 2 we manipulated the subjective reinforcement value of the reward by varying reward type and delay to reinforcement and found that delay to reinforcement had no impact on choice behavior, while increasing the value of the reward significantly improved performance by both species. The results of this study indicate that species presented with identical tasks may respond differently to methodological factors such as stimulus and reward types, resulting in significant differences in choice behavior that may lead to spurious suggestions of species differences in cognitive abilities. 相似文献

In a two-choice discrimination learning paradigm, a U-shaped function was found between trials to criterion and the number of sides comprising the random figure discriminanda. These data are consistent with results from human Ss and suggest similar information processing capabilities in the two species. Changing the orientation of the stimulus figures after the discrimination had been learned only partially disrupted subsequent discrimination performance. Any single difference in selected form attributes between the two figures comprising a problem was not a good predictor of learning speed, suggesting that monkeys use a combination of such factors. 相似文献

Current models of instructional design assume that concepts are (a) classifying rules, (b) components of a more complex network or schema in memory, and (c) evaluated/taught by classification performance. Based on current research and theory, however, concepts should be viewed as conceptual tools rather than classification rules. Concepts may be schemas or networks in themselves, as a complex arrangement of declarative, procedural, and inferential knowledge. Concept learning may be measured by concept use and inferences as well as classification and taught via analogies, learning strategies, use/inference practice, and rational-set generators. 相似文献

The aim of this paper is to offer further empirical evidence in support of Bernstein's concept of code from the social semiotic perspective of systemic functional linguistics. When the concept of code was first introduced in the 1960s, it was severely criticised by many famous socio-linguists. It will be argued that these socio-linguists failed to understand the significance of language as a meaning potential, and so they also failed to appreciate the inherent relation between meaning and mental development (Halliday, 1975; Vygotsky, 1978). The concept of code is important in any viable theory of mental development which does not hide behind a mythical homogeneity. Human beings develop different forms of consciousness, and code theory offers a detailed and coherent account of both the social origin and the nature of this variation. In fact, the panoramic scope of Bernstein's sociological theory clarifies the relations of social positioning, coding orientation, communication, and consciousness to learning in official pedagogic sites. In presenting some of the results of my investigation in variant forms of communication between mothers and their young children, I will show that: (a) the variation is systematic, (b) the nature of the variation needs Bernstein's code theory for its interpretation, and (c) the fact of variation can only be accounted for by its relation to social positioning. 相似文献

Four experiments examined generalization of latent inhibition (LI) as a function of the length of preexposure in a conditioned
taste aversion procedure with rats. Experiment 1 showed that one or four nonreinforced presentations of a flavor compound (BX) retarded subsequent conditioning to another
compound (AX). However, after eight presentations of BX, conditioning to AX occurred at the same rate as with no preexposure.
These results indicate that generalization of LI decreased as the length of preexposure to BX increased. Experiment 2 replicated this effect of reducing generalization, as well as demonstrating that LI actually increased as the length of preexposure
to AX increased. Experiment 3 extended the generality of the effect to a procedure in which both BX and AX were preexposed. Experiment 4 demonstrated a similar reducing-generalization effect when generalization of LI from BX to X was assessed. All of these data
are consistent with the notion that prolonged preexposure to BX enhances its discriminability. Different learning mechanisms
that might be responsible for this perceptual learning effect are discussed. 相似文献

Using a lexical decision task, the effects of frequency and number of meanings are investigated for fast and slow readers. It is shown that different patterns of results emerge for fast and slow readers. For fast readers there are general effects of both frequency and number of meanings; for slow readers the effects are considerably attenuated. 相似文献

The different tools of learning potential assessment rest on a mediation stage of some learning experience between a pre-test and a post-test. Althouth mediation might correspond to a broad range of educative behaviors, in these tools, as can be seen in this issue, it most often takes the form of quite direct instructions of cognitive strategies or of more general solving principles: As if the subject’s own activity would be totally substituted by the mediation during a mediated learning experience. From a constructivist conception of the development this view of the nature of mediation is indeed too narrow and too restrictive and raises some basic questions: What might be the meaning of a cognitive potential revealed only by direct instruction? How to relate learning potential and cognitive development? How to transform potentialities in subsequent cognitive development. This paper tackles these issues from a discussion of the Feuerstein’s distinction of mediated learning experience versus learning by direct exposure to sources of stimuli. From a constructivist view of cognitive functioning and cognitive development, it tries to broaden what mediation might be in the assessment of learning potential as well as in cognitive education programs. 相似文献

This article describes an approach for training a variety of species to learn the abstract concept of same/different, which in turn forms the basis for testing proactive interference and list memory. The stimulus set for concept-learning training was progressively doubled from 8, 16, 32, 64, 128 . . . to 1,024 different pictures with novel-stimulus transfer following learning. All species fully learned the same/different abstract concept: capuchin and rhesus monkeys learned more readily than pigeons; nutcrackers and magpies were at least equivalent to monkeys and transferred somewhat better following initial training sets. A similar task using the 1,024-picture set plus delays was used to test proactive interference on occasional trials. Pigeons revealed greater interference with 10-s than with 1-s delays, whereas delay time had no effect on rhesus monkeys, suggesting that the monkeys’ interference was event based. This same single-item same/different task was expanded to a 4-item list memory task to test animal list memory. Humans were tested similarly with lists of kaleidoscope pictures. Delays between the list and test were manipulated, resulting in strong initial recency effects (i.e., strong 4th-item memory) at short delays and changing to a strong primacy effect (i.e., strong 1st-item memory) at long delays (pigeons 0-s to 10-s delays; monkeys 0-s to 30-s delays; humans 0-s to 100-s delays). Results and findings are discussed in terms of these species’ cognition and memory comparisons, evolutionary implications, and future directions for testing other species in these synergistically related tasks. 相似文献

Two experiments were performed to evaluate the effects of definition adjunct questions on concept learning. Each experiment included 132 undergraduates at a large midwestern university. In both experiments, subjects studied a passage containing matched or unmatched application questions only, matched or unmatched application questions preceded by a definition question, definition questions only, or no questions at all. The critical attributes of the to-be-learned concepts were more salient in the sets of examples and nonexamples presented in the matched application questions than in the unmatched application questions. Subjects took a criterion test which consisted of novel matched and unmatched application questions. In both experiments, only unmatched application adjunct questions preceded by a definition question produced significantly higher performance on the criterion questions than definition questions only. The discussion focused on the importance of definition questions for effective use of different types of application questions. 相似文献
