12-month-old infants were familiarized either tactually or visually with objects and then tested for visual recognition memory using either (1) the familiar and a novel object, (2) colored pictures of the objects, or (3) outline drawings of them. In Study 1, infants showed recognition memory on all 3 visual intramodal problems but showed cross-modal transfer only when objects were used as test stimuli. With increased familiarization times in Study 2, transfer from tactually presented samples to both pictorial displays was achieved, indicating that after feeling an object the infants were able to recognize it visually solely on the basis of its contour. With reduced familiarization times in Study 3, there was no evidence for transfer from visually presented samples to the 2 pictorial displays, replicating the pattern of results observed cross-modally in Study 1 and suggesting that, at least in certain respects, cross-modal and intramodal perception follow similar principles. 相似文献

This study examines if and how the presence of an adult as a receptive agent of children’s drawings has an effect on the early production of pictorial symbols by emphasizing the children’s referential intention as drawers. To this end, we compared three-year-old children’s representational drawings with a model in four experimental conditions, three conditions with an adult as a receptive agent and one condition without a receiver. In the conditions with a receiver (Linguistic Feedback, Graphic Demonstration and Graphic Product) children were explicitly asked to draw for an adult, who had to use the children’s pictures to find hidden objects in identical boxes; the conditions differed in the adult’s actions with non-representational drawings. The results indicate that the presence of the receiver had an impact on representational production only when the adult demonstrated how to create the drawings with the intent of communicating the identity of the objects (Graphic Demonstration). Although drawing is typically viewed as a solitary activity, these results suggest that representational drawings may emerge in communicative contexts between drawers and receivers. 相似文献

Early understanding and production of graphic symbols 总被引：3，自引：0，他引：3

Young children's ability to understand and produce graphic symbols within an environment of social communication was investigated in two experiments. Children aged 2, 3, and 4 years produced graphic symbols of simple objects on their own, used them in a social communicative game, and responded to experimenter's symbols. In Experiment 1 (N = 48), 2-year-olds did not effectively produce symbols or use the experimenter's symbols in the choice task, whereas 3- and 4-year-olds improved their drawings following the game and performed above chance with the experimenter's symbols. Ability to produce an effective graphic symbol was correlated with success on a task that measured understanding of the experimenter's symbols, supporting the claim that children's ability to produce a graphic symbol rests on the understanding of the symbolic function of pictures. In Experiment 2, 32 children aged 3 and 4 years improved their third set of drawings when they received feedback that their drawings were not effective communications. The results suggest that production and understanding of graphic symbols can be facilitated by the same social factors that improve verbal symbolic abilities, thereby raising the question of domain specificity in symbolic development. 相似文献

Previous research suggests that model competence does not emerge until relatively late in infancy (20-26 months). Development was systematically analyzed within 3 key areas--count noun learning, dual representation, and categorization-hypothesized to support the emergence of model competence in the second year. In an object-handling preferential looking task, 21- to 26-month-olds matched model objects to referents only when count noun knowledge was high. When dual representation demands were reduced through the use of pictures in place of model objects, 20-month-olds with low count noun vocabularies succeeded in relating symbols to referents. Finally, change in infants' construal of a model object as a member of a category was documented between 14 and 20 months of age. 相似文献

Infants’ pointing gestures are a critical predictor of early vocabulary size. However, it remains unknown precisely how pointing relates to word learning. The current study addressed this question in a sample of 108 infants, testing one mechanism by which infants’ pointing may influence their learning. In Study 1, 18‐month‐olds, but not 12‐month‐olds, more readily mapped labels to objects if they had first pointed toward those objects than if they had referenced those objects via other communicative behaviors, such as reaching or gaze alternations. In Study 2, when an experimenter labeled a not pointed‐to‐object, 18‐month‐olds’ pointing was no longer related to enhanced fast mapping. These findings suggest that infants’ pointing gestures reflect a readiness and, potentially, a desire to learn. 相似文献

Morphing images: a potential tool for teaching word recognition to children with severe learning difficulties 总被引：1，自引：0，他引：1

Children with severe learning difficulties who fail to begin word recognition can learn to recognise pictures and symbols relatively easily. However, finding an effective means of using pictures to teach word recognition has proved problematic. This research explores the use of morphing software to support the transition from picture to word recognition. Morphing software was used to teach word recognition to a group of eight children who were previously unable to recognise words. At the end of 16 teaching sessions, in a related design, the morphing technique was more effective than a word‐alone approach ( p < 0.05, one‐tailed). These results support the use of techniques such as symbol accentuation ( Miller & Miller, 1971 ) and challenge the concept that the use of pictorial information is inherently detrimental to learning in this context, in comparison to the repeated presentation of words alone. The recent advent of accessible morphing software removes previous barriers to this type of approach. The investigation highlights several useful avenues for future research, in particular, the use of mnemonic elements within morphing teaching methods. 相似文献

This study examined the role of social-referential context in 13- and 18-month-olds' mapping of verbal and nonverbal symbols to object categories. Infants heard either novel words or novel nonverbal sounds in either a referential or nonreferential context. In all conditions, an experimenter engaged in a social-referential interaction and the label was produced while the infant's attention was directed to the referent. In the referential condition, labels were produced by the experimenter within the context of a familiar naming routine. In the nonreferential condition, labels were emitted from a baby monitor placed near the infant. The study subsequently tested infants' mapping of the symbols to the referent objects using a forced-choice procedure. Although the results for the 18-month-olds were strongest, infants at both ages showed evidence of learning both words and sounds in the referential condition and failed to learn them in the nonreferential condition. Thus, infants successfully learned both words and sounds under the same circumstances at both ages. These findings suggest that the social-referential context, and not the symbolic form per se, determine infants' success at symbol learning. 相似文献

The use of visualisation in learning material is increasing rapidly. Three major categories of pictures or illustrations are distinguished: representational pictures, logical pictures, and pictorial analogies. This article concentrates on pictorial analogies of which the cognitive functioning depends on identical relations between two non-identical domains. To get more insight into the crucial parameters of pictorial analogies in combination with expository text, two investigatory studies with physics materials are reported. The results show that the use of pictorial analogies can improve learning significantly if they are designed properly and used together with the expository text to be studied. Pictorial analogies should be carefully developed in regard to high structural similarity between the base and the target domain. Understanding of the analogical relationship is supported by inter-connecting the information text closely with references to the relevant features of the pictorial analogy. 相似文献

This study examined whether 12‐month‐olds will accept words that differ phonologically and phonetically from their native language as object labels in an associative learning task. Sixty infants were presented with sets of English word–object (N = 30), Japanese word–object (N = 15), or Czech word–object (N = 15) pairings until they habituated. Infants associated CVCV English, CCVC English, and CVCV Japanese words, but not CCVC Czech words, with novel objects. These results demonstrate that by 12 months of age, infants are beginning to apply their language‐specific knowledge to their acceptance of word forms. That is, they will not map words that violate the phonotactics of their native language to objects. 相似文献

Associations between infants' transition to walking and object activities were examined. Fifty infants were observed longitudinally during home observations. At 11 months, all infants were crawlers; at 13 months, half became walkers. Over age, infants increased their total time with objects and frequency of sharing objects with mothers. Bidirectional influences between locomotion and object actions were found. Walking was associated with new forms of object behaviors: Walkers accessed distant objects, carried objects, and approached mothers to share objects; crawlers preferred objects close at hand and shared objects while remaining stationary. Earlier object activities predicted walking status: Crawlers who accessed distant objects, carried objects, and shared objects over distances at 11 months were more likely to walk by 13 months. 相似文献

In a series of 4 studies, we explored preschoolers' understanding of thought bubbles. Very few 3-year-olds or 4-year-olds we tested knew what a thought-bubble depiction was without instruction. But, if simply told that the thought bubble "shows what someone is thinking," the vast majority of 3-year-olds and 4-year-olds easily understood the devices as depicting thoughts generally and individual thought contents specifically. In total, these children used thought-bubble depictions to ascertain the contents of characters' thoughts in a variety of situations; appropriately distinguished such depictions from mere associated actions or objects; described thought bubbles in the language of mental states; judged that persons' thoughts in these depictions were subjective in the sense of person-specific (and hence 2 people can have different thoughts about the same state of affairs); and judged that thought-bubble thoughts ( a ) were representational in the sense of depicting or showing some other state of affairs, ( b ) were mental and thus showed intangible, private, internal thoughts unlike real pictures or photographs, and ( c ) can be false, that is, can depict a person's misrepresentation of some state of affairs. We discuss the implications of these findings for young children's understanding of thoughts and thought bubbles, for their learning and comprehension of pictorial conventions, and for the use of thought bubbles to assess children's early understanding of mind. 相似文献

Three experiments examined the effect of practice on memory performance by 18-month-old infants. Infants were tested using an imitation paradigm; an adult demonstrated a series of actions with objects and infants were given the opportunity to reproduce those actions following a delay. Some infants practiced the target actions before the retention interval (practice) and some did not (no practice). In Experiment 1, a reminder treatment alleviated forgetting by infants who practiced but failed to alleviate forgetting by infants who did not practice. In Experiments 2A and 2B, infants who practiced generalized to novel test stimuli after a 24-hr delay, whereas infants without practice did not. Results suggest practice influences the accessibility and generality of infants' memories. 相似文献

Two experiments examined whether 18-month-olds learn from emotions directed to a third party. Infants watched an adult perform actions on objects, and an Emoter expressed Anger or Neutral affect toward the adult in response to her actions. The Emoter then became neutral and infants were given access to the objects. Infants' actions were influenced by their memory of the Emoter's affect. Moreover, infants' actions varied as a function of whether they were currently in the Emoter's visual field. If the previously angry Emoter was absent (Experiment 1) or turned her back (Experiment 2), infants did not use the prior emotion to regulate their behavior. Infants learn from emotional eavesdropping, and their subsequent behavior depends on the Emoter's orientation toward them. 相似文献

The ability of infants aged 8–12 months to coordinate their arm and trunk movements to contact an object located in different positions was investigated in 2 experiments. In the first, 8- and 10-month-old infants reached for near objects but both reached and leaned for more distant ones indicating that they perceived that forward leaning extends the range of contact beyond that of reaching alone. In addition, arm and trunk movements were initiated simultaneously; visual information concerning object distance was sufficient to activate an integrated reaching-and-leaning response. Object distances were increased and a mechanical aid was provided on half the trials in the second experiment with 10- and 12-month-old infants. For both age groups the degree of leaning was reduced for objects that were out of reach without the aid. Only older infants were able to use the aid to extend partially their range of contact. Overall the results support the conclusions that, by at least 8 months, infants perceive that leaning extends their effective reaching space; by 10 months they perceive the limits within which reaching together with leaning is likely to be effective; and by 12 months they begin to perceive how this space may be extended by a mechanical aid. 相似文献

Summary Pictorial communication of shape and form is not simply a learned visual language. Whatever processes of learning, if any,
underly our ability to perceive represented surfaces’ edges-without which the communication of shape is impossible-in response
to outline drawings, probably occurs very early in life in consequence of our normal commerce with spatial objects. Although
this probability makes the problems of“learning to see pictures”relatively inaccessible, it simplifies the study of the rules
which govern edge- and surface-perception in pictures. The applicability of such rules depends, eventually, on knowing

Previous research has shown that pictures can be effective in enhancing text memory. For example, Waddill and McDaniel (1992) found that pictures depicting detail information in an expository text effectively enhanced recall of those details and pictures depicting relational information effectively enhanced recall of those relations. However, the research on picture enhancement effects raises the question of whether the mnemonic value of pictures is simply a by‐product of having drawn attention to parts of the text through selective repetition of text content. The present study addressed the question by comparing the relative effectiveness of pictures versus simple verbal captions in promoting text memory. The results replicated the Waddill and McDaniel (1992) pictorial enhancement effect. However, the results showed that repeating the targeted information in a verbal caption was as effective as providing a pictorial illustration, thus suggesting that repetition of text content rather than nonverbal pictorial illustrations produced the effect. The findings generalized across three texts that differed in the amount of spatial content they conveyed. 相似文献

In 4 experiments 120 three- to four-year-old nonreaders were asked the identity of a symbolic representation as it appeared with different objects. Consistent with Bialystok (2000), many children judged the identity of written words to vary according to the object with which they appeared but few made such errors with recognizable pictures. Children also made few errors when the symbols were unrecognizable pictures. In Experiments 2 to 4 this pattern of responses was preserved in conditions that made it unlikely or impossible for children to answer correctly by taking the symbol to refer to one of the objects with which it appeared. Instead, correct answers required children to appreciate that the symbol had a generic, abstract meaning. 相似文献

Infants’ transfer of information from pictures to objects was tested by familiarizing 9‐month‐olds (N = 31) with either a color or black‐and‐white photograph of an object and observing their preferential reaching for the real target object versus a distractor. One condition tested object recognition by keeping both objects visible, and the other tested object representation by hiding both objects. On visible trials, infants reached more for the distractor, indicating they recognized the target object from its picture. On hidden trials, infants reached more for the target object, suggesting they formed a continued representation of the object based on its picture. Photograph color had no effect. Infants thus show picture‐to‐object transfer by 9 months with preferential reaching, even with black‐and‐white pictures. 相似文献
