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

Eye movements were recorded while sixty-two 1-year-olds, 4-year-olds, and adults watched television. Of interest was the extent to which viewers looked at the same place at the same time as their peers because high similarity across viewers suggests systematic viewing driven by comprehension processes. Similarity of gaze location increased with age. This was particularly true immediately following a cut to a new scene, partly because older viewers (but not infants) tended to fixate the center of the screen following a cut. Conversely, infants appear to require several seconds to orient to a new scene. Results are interpreted in the context of developing attention skills. Findings have implications for the extent to which infants comprehend and learn from commercial video. 相似文献

Imitation of televised models by infants 总被引：2，自引：0，他引：2

Studies indicate that infants in our culture are exposed to significant amounts of TV, often as a baby-sitting strategy by busy caretakers. The question arises whether TV viewing merely presents infants with a salient collection of moving patterns or whether they will readily pick up information depicted in this 2-D representation and incorporate it into their own behavior. Can infants "understand" the content of television enough to govern their real-world behavior accordingly? One way to explore this question is to present a model via television for infants to imitate. Infants' ability to imitate TV models was explored at 2 ages, 14 and 24 months, under conditions of immediate and deferred imitation. In deferred imitation, infants were exposed to a TV depiction of an adult manipulating a novel toy in a particular way but were not presented with the real toy until the next day. The results showed significant imitation at both ages, and furthermore showed that even the youngest group imitated after the 24-hour delay. The finding of deferred imitation of TV models has social and policy implications, because it suggests that TV viewing in the home could potentially affect infant behavior and development more than heretofore contemplated. The results also add to a growing body of literature on prelinguistic representational capacities. They do so in the dual sense of showing that infants can relate 2-D representations to their own actions on real objects in 3-D space, and moreover that the information picked up through TV can be internally represented over lengthy delays before it is used to guide the real-world action. 相似文献

The relation between attachment to mother and knowledge of self and mother in 2 domains was assessed in 1- to 3-year-old infants. Infants' featural knowledge was measured by featural recognition, name, possession, and gender. In this domain, no difference between the 2 attachment classifications was obtained at 1 year of age, but significant and increasingly large differences between securely and insecurely attached infants were found at 2 and 3 years of age. The second domain measured infants' actions on self and mother in the context of symbolic play. Regardless of age, infants who were securely attached to mother acted on self and mother with greater complexity than did infants who were insecurely attached. Attachment was related equally to the complexity of infants' knowledge of self and mother. These data were discussed in the context of the development of infants' internal working models of attachment and the onset of representational ability. 相似文献

Function has been considered important in numerous literatures in the study of cognitive development, yet little is known about what and how infants learn about function. Five experiments examined what 10-month-old infants (N=80) learn about functions that involve a sound produced when an object is acted on. Infants habituated to a single object (Experiment 1) or multiple objects that performed the same function (Experiment 2) learned both the actions and the sounds. Infants did not appear to learn relations between actions and sounds (Experiment 3) or appearances and sounds (Experiment 4), although they did learn the relations between appearances and actions (Experiment 5). These results are discussed in terms of how infants learn about object function. 相似文献

Infants can imitate a novel action sequence from television and picture books, yet there has been no direct comparison of infants' imitation from the 2 types of media. Varying the narrative cues available during the demonstration and test, the current experiments measured 18- and 24-month-olds' imitation from television and picture books. Infants imitated from both media types when full narrative cues (Experiment 1; N = 76) or empty, meaningless narration (Experiment 2; N = 135) accompanied the demonstrations, but they imitated more from television than books. In Experiment 3 (N = 27), infants imitated from a book based on narration alone, without the presence of pictures. These results are discussed in relation to age-related changes in cognitive flexibility and infants' emerging symbolic understanding. 相似文献

The role of maternal affect mirroring on the development of prosocial behaviors and social expectancies was assessed in forty-one 2- to 3-month-old infants. Prosocial behavior was characterized as infants' positive behavior and increased attention toward their mothers. Social expectancies were defined as infants' expectancy for affective sharing. Mothers and infants were observed twice, approximately 1 week apart. During Visit 1, mothers and infants were videotaped while interacting over television monitors for 3 min. During Visit 2, infants engaged in a live, 3-min interaction with their mothers over television monitors (live condition) and they also viewed a replay of their mothers' interaction from the preceding week (replay condition). The order of conditions was counterbalanced. Maternal affect mirroring was measured according to the level of attention maintenance, warm sensitivity, and social responsiveness displayed. A natural split was observed with 58% of the mothers ranking high and 42% ranking low on these affect mirroring measures (HAM and LAM, respectively). Infants in the HAM group ranked high on prosocial behaviors and social expectancy--they discriminated between live and replay, conditions with smiles, vocalizations, and gazes. Infants in the LAM group ranked low on these variables--they gazed longer during the live condition than during the replay condition, but only when the live condition was presented first; however, they did not smile or vocalize more. These findings indicate that there is a relation between affect mirroring and social expectancies in infants. 相似文献

Infants’ memories are highly specific to their training stimuli; they rarely transfer learned responding. In two experiments, we asked whether sensory preconditioning facilitates the transfer of deferred imitation. In Experiments 1A and 1B, 6-month-olds were simultaneously preexposed to Puppets A and B and then saw target actions modeled on Puppet A. The infants associated the paired puppets and imitated the actions on Puppet B. In Experiment 2, the preexposure procedure was repeated, but the actions were modeled on Puppet A with a toy train in view. The infants also associated Puppet A and the train: Either object effectively reactivated both forgotten memories; thereafter, the infants again imitated the actions on Puppet B. These findings reveal that infants form specific and enduring associations between stimuli they have merely seen together. These associations facilitate the transfer of deferred imitation, both directly and indirectly, through connections to other associations. 相似文献

This study investigated children's understanding of others' intentions in a social learning context. Specifically, it investigated whether knowing an adult's prior intention before the adult gives a demonstration influences what children learn from the demonstration. In the five main experimental conditions, ninety-six 2-year-old children watched as an experimenter (E) pulled out a pin and opened the door of a box. Children in two No Prior Intention conditions saw this demonstration alone or paired with an irrelevant action. Children in three Prior Intention conditions knew what E was trying to do before the demonstration: they first saw E either attempt unsuccessfully to open the door, or visit and open several other containers, or they first saw that the door opened. Children opened the box themselves more often in each of these three conditions than in the two No Prior Intention conditions, even though children in all five conditions saw the exact same demonstration of how to open the box. 相似文献

An exploratory study was carried out to investigate the relative effectiveness of news stories watched on television and news stories read by children. Children aged 10 to 12 (n = 123) either watched five news stories or read print versions of the same news stories. In each condition, half of the children expected a retention test, whereas the other children did not. Results indicated that children who did not expect a retention test learned more from television news than from printed news. Among children who expected a retention test, televised and printed news were recalled about equally well. 相似文献

The availability of educational programming aimed at infants and toddlers is increasing, yet the effect of video on language acquisition remains unclear. Three studies of 96 children aged 30–42 months investigated their ability to learn verbs from video. Study 1 asked whether children could learn verbs from video when supported by live social interaction. Study 2 tested whether children could learn verbs from video alone. Study 3 clarified whether the benefits of social interaction remained when the experimenter was shown on a video screen rather than in person. Results suggest that younger children only learn verbs from video with live social interaction whereas older children can learn verbs from video alone. Implications for verb learning and educational media are discussed. 相似文献

There is little evidence that infants learn from infant‐oriented educational videos and television programming. This 4‐week longitudinal experiment investigated 15‐month‐olds' (N = 92) ability to learn American Sign Language signs (e.g., patting head for hat) from at‐home viewing of instructional video, either with or without parent support, compared to traditional parent instruction and a no‐exposure control condition. Forced‐choice, elicited production, and parent report measures indicate learning across all three exposure conditions, with a trend toward more robust learning in the parent support conditions, regardless of medium. There were no differences between experimental and control conditions in the acquisition of corresponding verbal labels. This constitutes the first experimental evidence of infants' ability to learn expressive communication from commercially available educational videos. 相似文献

A total of 111 children, 55 aged 8 to 9 years and 56 aged 14 to 15 years of age, watched one of two single‐topic prime‐time science programmes. Recall and comprehension scores following the viewing of the programmes were assessed. In addition, a number of demographic factors including age, sex, linguistic fluency, prior television viewing and reading habits were investigated as possible predictors of learning from television. It was found that age was a significant factor in both recall and comprehension, but even more important was general knowledge. Sex and linguistic fluency was neither systematically nor frequently associated with good performance. Prior viewing habits concerning science programmes on television and reading behaviour were found to have particular effects but were not major predictors of performance. Knowledge growth (defined as differences in performance between pre‐ and post‐test performance on key, repeated, items specifically addressed by the viewed programme) was consistently observed. This major finding indicated clearly that children can learn prime‐time television science information. 相似文献

A total of 122 parent–infant dyads were observed as they watched a familiar or novel infant‐directed video in a laboratory setting. Infants were between 12–15 and 18–21 months old. Infants were more likely to look toward the TV immediately following their parents' look toward the TV. This apparent social influence on infant looking at television was not solely due to the common influence of the television program on looking behavior. Moreover, infant looks that were preceded by parent looks tended to be longer in length than those that were not preceded by parent looks, suggesting that infants assign greater value to media content attended to by their parents. Thus, parental patterns of attention to television may influence early viewing behavior. 相似文献

Exploring the presence of imitation during early infancy 总被引：3，自引：1，他引：3
2 investigations of early imitative ability were conducted with cross-sectional samples of infants between 4 and 21 weeks. Study 1 involved 2 rounds of modeling 5 gestures to infants. In Study 2, the number of modeled gestures was reduced to 3, but each one was modeled many more times--for the duration of the infant's attention over a 3-min period. When frequencies of reproduction of a modeled act were compared against baseline frequencies and against average frequencies of the act during periods when other actions were modeled, several main results were obtained. First, the most general finding was that imitative-like matching of modeled gestures was the exception, not the rule, at all ages. Second, even where significantly greater frequencies of a gesture occurred during modeling than during control periods, it was always a partial and incomplete version of the modeled act that was reproduced, not a well-formed copy of the adult's gesture. Finally, where results were consistent with an interpretation of imitation, as with responses to tongue protrusion modeling, the effect was restricted to the youngest ages: 4-6 weeks. Given the restricted evidence for imitation, and the fact that neither linear nor curvilinear growth trends were apparent, the most appropriate explanation for the reproduction of tongue protrusions at the youngest age is to be sought in terms of a reflexive or fixed action pattern type of response. 相似文献

A sample of 271 3- and 5-year-olds and their families participated in a 2-year longitudinal study of television viewing patterns. 5 1-week diaries for all family members were collected at 6-month intervals. Programs were categorized as: (1) child informative, (2) child entertainment, (3) news and informative, (4) sports, (5) comedy, (6) drama, (7) action-adventure, and (8) variety-game. The majority of child programs were viewed without parents, while the majority of adult programs were watched with parents. Coviewing patterns of adult programs were predicted from parents' individual viewing habits, but not from the child's. Coviewing declined with age. Parental encouragement and regulation of viewing were orthogonal. Children whose parents encouraged viewing watched more child informative programming; children of restrictive parents watched less entertainment programming. Encouraging parents coviewed more than nonencouraging parents. Results support the assertion that parental viewing preferences, habits, and orientations toward television influence children's viewing, both with and without parents. 相似文献

The purpose of this study was to examine what distance education-related skills and knowledge television production specialists had to learn in order to perform their jobs. The purposive sample for this study consisted of 12 full-time television production specialists who develop live, interactive, video-based educational programs at American universities. However, prior to employment at their respective universities, these television production specialists had no experience or educational background in the field of distance education. Qualitative methods were used to collect data. The analysis gave rise to the finding that television production specialists had to learn skills in two major areas—technical skills and personal/interpersonal skills—and knowledge of instructional design methods. 相似文献

Infants'' Detection of Correlations among Feature Categories 总被引：2，自引：0，他引：2
Barbara Younger 《Child development》1990,61(3):614-620
The present study demonstrates that the infant's ability to detect correlations among attributes extends to correlations among feature categories of the type we might expect to be useful in forming natural object categories. 48 10- and 13-month-old infants were tested using an infant-control habituation procedure. Infants initially were exposed to as many as 12 different animals. 2 attributes were perfectly correlated within the set of habituation stimuli. For example, animals with feathered tails had ears, and animals with furry tails had antlers. The appearance of the correlated features varied across the set of 12 animals. Infants' sensitivity to the pattern of correlation existing within the habituation set was demonstrated by their responses to new stimuli following habituation. Infants generalized habituation to a new animal that preserved the experienced pattern of correlation, but showed an increase in looking to a stimulus that contained a novel combination of the same features. 相似文献
