The role of person familiarity in young infants' perception of emotional expressions 总被引：2，自引：0，他引：2
This research investigated the role of person familiarity in the ability of 3.5-month-old infants to recognize emotional expressions. Infants (N = 72) were presented simultaneously with two filmed facial expressions, happy and sad, accompanied by a single vocal expression that was concordant with one of the two facial expressions. Infants' looking preferences and facial expressions were coded. Results indicated that when the emotional expressions were portrayed by each infant's own mother, infants looked significantly longer toward the facial expressions that were accompanied by affectively matching vocal expressions. Infants who were presented with emotional expressions of an unfamiliar woman did not. Even when a brief delay was inserted between the presentation of facial and vocal expressions, infants who were presented with emotional expressions of their own mothers looked longer at the facial expression that was sound specified, indicating that some factor other than temporal synchrony guided their looking preferences. When infants viewed the films of their own mothers, they were more interactive and expressed more positive and less negative affect. Moreover, infants produced a greater number of full and bright smiles when the sound-specified emotion was "happy," and particularly when they viewed the happy expressions of their own mothers. The average duration of negative affect was significantly longer for infants who observed the unfamiliar woman than for those who observed their own mothers. These results show that when more contextual information-that is, person familiarity-was available, infants as young as 3.5 months of age recognized happy and sad expressions. These findings suggest that in the early stages of development, infants are sensitive to contextual information that potentially facilitates some of the meaning of others' emotional expressions. 相似文献

Convergent methodologies from studies of fear-potentiated startle in animals and studies of affective modulation of reflex blinks in humans were adapted in order to investigate infants' sensitivity to affective information conveyed by facial expressions of emotion. While 5-month-old infants viewed photographic slides of faces posed in happy, neutral, or angry expressions, a brief acoustic noise burst was presented to elicit the blink component of human startle. Blink size was augmented during the viewing of angry expressions and reduced during happy expressions. Infants did not show marked changes in behavioral reactions to the positive, neutral, and negative slides, although motor activity was slightly reduced during negative slides. Results suggest that, by 5 months, infants react to affective information conveyed by unfamiliar human faces. Potential mechanisms mediating the influence of affective stimuli on reflex excitability are considered. 相似文献

The impact of 2 types of learning experiences on children's perception of multimodal emotion cues was examined. Children (aged 7-12 years) were presented with conflicting facial and vocal emotions. The effects of familiarity were tested by varying whether emotions were presented by familiar or unfamiliar adults. The salience of particular emotional expressions was tested by contrasting the performance of physically abused and nonabused children. Children exhibited a preference for auditory expressions produced by their mothers but not by strangers. Additionally, abused children were biased to rely on auditory cues when their own abusive mother was expressing anger. These results are discussed in terms of the impact of both typical and atypical early experiences on the development of emotion perception. 相似文献

Few studies have examined whether familiarity of partner affects social responses in children with autism. This study investigated heart rate regulation (respiratory sinus arrhythmia [RSA]: The myelinated vagus nerve's regulation of heart rate) and temporal–parietal electroencephalogram (EEG) activity while nineteen 8- to 12-year-old children with autism and 14 controls viewed videos of a familiar and an unfamiliar person reading a story. Children with autism had lower overall RSA levels and exhibited decreased RSA to the unfamiliar person, versus control children. Both groups decreased temporal–parietal EEG activity to the unfamiliar person. Higher RSA was related to higher social skill ratings and fewer problem behaviors. Thus, the social difficulties of children with autism may be characterized by specific mobilization to unfamiliar people. 相似文献

200 pairs of twins were assessed at 14 months of age in the laboratory and home. Measures were obtained of temperament, emotion, and cognition/language. Comparisons between identical and fraternal twin correlations suggest that individual differences are due in part to heritable influences. For temperament, genetic influence was significant for behavioral observations of inhibition to the unfamiliar, tester ratings of activity, and parental ratings of temperament. For emotion, significant genetic influence was found for empathy and parental ratings of negative emotion. The estimate of heritability for parental report of expression of negative emotions was relatively high, whereas that for expression of positive emotions was low, a finding consistent with previous research. For cognition and language, genetic influence was significant for behavioral indices of spatial memory, categorization, and word comprehension. Shared rearing environment appears influential for parental reports of language and for positive emotions, but not for other measures of emotion or for temperament. 相似文献

This article evaluates the extent to which infants' expressive modalities of face, gaze, voice, gesture, and posture form coherent affective configurations and whether these configurations are related to specific interactive contexts. 50 6-month-old infants and their mothers were videotaped in Tronick's Face-to-Face Still-Face Paradigm. The infants' gaze, voice, gestures, self-regulatory, and withdrawal behaviors were coded with the Infant Regulatory Scoring System (IRSS). The infants' facial expressions were coded with Izard's AFFEX system. Contingency analyses of IRSS behaviors and AFFEX expressions revealed 4 distinct affective configurations: Social Engagement, Object Engagement, Passive Withdrawal, and Active Protest. These affective configurations were differentially distributed among the different interactive contexts of the Face-to-Face Still-Face Paradigm. It is suggested that behaviors and facial expressions are fundamental expressive units flexibly organized into configurations that convey messages about the infant's internal state and intentions. Furthermore, it is hypothesized that the basic units of the infant's experience are these distinct affective configurations of emotion and behavior. 相似文献

OBJECTIVE: There were two main aims: first, to assess parental attributions about child behavior in abuse-risk and nonclinic parents. Second, to assess how attributions predict affective and behavioral reactions to child behavior. METHOD: Internal-external attributions relating to the causes of child behavior were compared across mothers at-risk of child abuse (n = 40) and mothers who reported no significant parental or child conduct or behavior problems (n = 20). Mothers' attributions about the causes of the behavior of their own child and an unfamiliar child were recorded in response to the presentation of videotaped excerpts of the behavior. RESULTS: Results highlighted that compared with nonclinic mothers, abuse-risk mothers had a tendency to attribute positive child behavior to more external causes and negative child behavior to more internal causes. Differences were also found between parental cognitions about clearly positive, clearly naughty, and ambiguous child behavior. In the abuse-risk group, positive child behavior predicted coercive parenting when it elicited angry feelings in the mother; ambiguous and naughty child behavior led to coercive parenting through valence ratings of "deviant" and attributions of "internality." Analyses within the abuse-risk group showed that parental attributions are predictive of parental coerciveness for unfamiliar behavior. As behavior becomes more familiar, ratings of its valence and the affect it elicits override attributional activity. CONCLUSIONS: Parental attributions about the causes of child behavior differ according to the valence and familiarity of that behavior, and discriminate between parents at risk for child abuse. Further, attributions are predictive of the affective and behavioral responses the parent makes to the child's behavior for ambiguous or unfamiliar behavior. Evidence was found for the validity of using videotaped stimuli of the behavior of known and unknown children as a method of assessing parental attributions. 相似文献

Establishing word-object relations: a first step 总被引：1，自引：0，他引：1
This work explores how infants in the early phases of acquiring language come to establish an initial mapping between objects and their labels. If infants are biased to attend more to objects in the presence of language, that could help them to note word-object object pairings. To test this, a first study compared how long 18 10-14-month-old infants looked at unfamiliar toys when labeling phrases accompanied their presentation, versus when no labeling phrases were provided. As predicted, labeling the toys increased infants' attention to them. A second study examined whether the presence of labeling phrases increased infants' attention to objects over and above what pointing, a powerful nonlinguistic method for directing infants' attention, could accomplish on its own. 22 infants from 2 age groups (10-14- and 17-20-month-olds) were shown pairs of unfamiliar toys in 2 situations: (a) in a pointing alone condition, where the experimenter pointed a number of times at one of the toys, and (b) in a labeling + pointing condition, where the experimenter labeled the target toy while pointing to it. While the pointing occurred, infants looked just as long at the target toy whether or not it was labeled. During a subsequent play period in which no labels were uttered, however, infants gazed longer at the target toys that had been labeled than at those that had not. Thus language can increase infants' attention to objects beyond the time that labeling actually occurs. These studies do not pinpoint which aspects of labeling behavior contribute to the attentional facilitation effect that was observed. In any case, however, this tendency for language to sustain infants' attention to objects may help them learn the mappings between words and objects. 相似文献

Seven-month-old infants' perception of positive (happy, interested) and negative (angry, sad) affective expressions was investigated using a preferential looking procedure (n = 20 in each of 6 conditions). The infants saw two videotaped facial expressions and heard a single vocal expression concordant with one of the facial expressions. The voice on the soundtrack was played 5 s out of synchrony with the ongoing affective visual display. Infants participated in one of six conditions (all possible pairs of the four expressive events). Infants' visual fixations to the affectively concordant and affectively discordant displays were recorded. Infants looked longer at the affectively concordant displays than at the affectively discordant displays in all conditions except the happy/sad and interested/sad conditions. For these two comparisons, facial discrimination was demonstrated by the infants' preferential looking at happy and interested expressions compared to the sad expression. Thus, 7-month-old infants discriminate among happy, interested, angry, and sad expressions, demonstrating differentiation among specific, dynamic expressions. The results are discussed in terms of the information specifying facial and vocal affect and the possible role of familiarity in learning to differentiate among affective expressions during infancy. 相似文献

In social contexts, people’s emotional expressions may disguise their true feelings but still be revealing about the probable desires of their intended audience. This study investigates whether children can use emotional expressions in social contexts to recover the desires of the person observing, rather than displaying the emotion. Children (7.0–10.9 years, N = 211 across five experiments) saw a protagonist express one emotional expression in front of her social partner, and a different expression behind her partner’s back. Although the protagonist expressed contradictory emotions (and the partner expressed none), even 7-year-olds inferred both the protagonist’s and social partner’s desires. These results suggest that children can recover not only the desire of the person displaying emotion but also of the person observing it. 相似文献

Acquiring Proper Nouns for Familiar and Unfamiliar Animate Objects: Two-Year-Olds' Word-learning Biases 总被引：1，自引：0，他引：1
D. Geoffrey Hall 《Child development》1991,62(5):1142-1154
In 2 studies, 2-year-old children learned a novel word modeled as a proper noun (e.g., "This is Zav") for an animate stuffed toy. Children who learned the word for a familiar object (i.e., one for which they knew a basic-level count noun for the kind) interpreted the word appropriately as a proper noun reliably more often than children who learned the word for an unfamiliar object (i.e., one for which they did not know such a count noun). When the creature was familiar, children typically interpreted the novel word as if it were a proper noun referring uniquely to the labeled individual. When the animal was unfamiliar, children frequently interpreted the word as if it were a count noun referring to a kind of object. Children's spontaneous comments during the tasks provided striking additional evidence that their interpretations of the proper noun varied with the familiarity of the object. The results suggest that young children's sensitivity to the form class of proper nouns is affected by the familiarity of the referent object. The findings are discussed in terms of interpretative biases in word learning. 相似文献

We examined the role of object kind familiarity (i.e., knowledge of a count noun for an object) on preschoolers' sensitivity to the relation between a novel word's form class (adjective or count noun) and its reference (to a material kind-property or to an object kind). We used a forced-choice match-to-target task, in which children learned a word for one object (e.g., a metal cup), and then chose between 2 other objects. One was from the same object kind but a different material kind (with different related properties, such as color and texture; e.g., a white plastic cup); the other was from a different object kind but the same material kind (with the same related properties; e.g., a metal spoon). In Experiment 1, children learned either a count noun (e.g., "This is a zav") or an adjective (e.g., "This is a zav one"). Within each form class, we crossed the familiarity of the referent object kind (familiar and unfamiliar) with the age of the children (2- and 4-year-olds). The principal finding was that in interpreting an adjective, 4-year-olds were more likely to choose the object sharing material kind with the target if the target was familiar than if it was unfamiliar. No such familiarity effect was evident among 2-year-olds. In Experiment 2, we employed a more unambiguously adjectival frame (e.g., "This is a very zav-ish one"), and replicated the results of Experiment 1. We interpret the results in terms of 2 proposed word learning biases: one that learners initially expect any word applied to an unfamiliar object to refer to a (basic-level) kind of object, and a second that learners prefer words to contrast in meaning. We consider several interpretations of the observed age difference. 相似文献

幼儿歌唱活动是幼儿艺术教育领域的一个重要组成部分,它从幼儿歌唱的角度促进幼儿情感、态度、能力、知识、技能的全面发展。因此,幼儿歌唱活动既要重视对幼儿情感、审美情趣的培养,又不能忽视对幼儿进行知识和技能的培养。我们强调的是不要“过份”强调“知识和技能”,但并不等于不要知识和技能。如果我们“过份”强调对幼儿进行知识和技能的训练,必然会限制教师和孩子们的想象力和创造力的发挥,这是片面的。因此,幼儿歌唱教育活动应当是促进幼儿的全面发展。 相似文献

Parents' physiological regulation may support infants' regulation. Mothers ( N = 152) and 6-month-old male and female infants were observed in normal and disrupted social interaction. Affect was coded at 1-s intervals and vagal tone measured as respiratory sinus arrhythmia (RSA). Maternal sensitivity was assessed in free play. Mothers and infants showed opposite patterns of RSA change. During disrupted interaction, mothers' RSA increased and infants' decreased, suggesting self-regulation of distress. During reunion, although the typical pattern was for infants to return to baseline levels, infants of sensitive mothers and sensitive mothers both showed a significant decrease in RSA from baseline. Mothers' and infants' physiological responses may be a function of mutual responsiveness. 相似文献

Although recent studies have convincingly demonstrated that emotional expressions can be judged reliably from actor-posed facial displays, there exists little evidence that facial expressions in lifelike settings are similar to actor-posed displays, are reliable across situations designed to elicit the same emotion, or provide sufficient information to mediate consistent emotion judgments by raters. The present study therefore investigated these issues as they related to the emotions of happiness, surprise, and fear. 27 infants between 10 and 12 months of age (when emotion masking is not likely to confound results) were tested in 2 situations designed to elicit hapiness (peek-a-boo game and a collapsing toy), 2 to elicit surprise (a toy-switch and a vanishing-object task), and 2 to elicit fear (the visual cliff and the approach of a stranger. Dependent variables included changes in 28 facial response components taken from previous work using actor poses, as well as judgments of the presence of 6 discrete emotions. In addition, instrumental behaviors were used to verify with other than facial expression responses whether the predicted emotion was elicited. In contrast to previous conclusions on the subject, we found that judges were able to make all facial expression judgments reliably, even in the absence of contextual information. Support was also obtained for at least some degree of specificity of facial component response patterns, especially for happiness and surprise. Emotion judgments by raters were found to be a function of the presence of discrete facial components predicted to be linked to those emotions. Finally, almost all situations elicited blends, rather than discrete emotions. 相似文献

The expressive behaviors of full-term and preterm infants and their mothers were examined during face-to-face interaction when the infants were approximately 2 1/2, 5, and 7 1/2 months old. Videotapes of the sessions were coded on a second-to-second basis using Izard's discrete emotion coding system. Overall, infants showed a linear increase in positive effect, especially interest and joy, and a corresponding decrease in negative affect, especially pain and knit brow, with age; decrease in negative affect was accounted for largely by the preterm infants. In terms of maternal responses, there was an increase in contingent responding to infant interest expressions and a decrease in contingent responding to infant pain expressions over time, especially in the case of the preterm infant. The data set as a whole was examined further to establish the directionality of influence between mothers and infants in change patterns over time. There was evidence of learning effects in infants as a function of maternal modeling and contingency patterns. Anomalies in maternal responses to preterm infant affect expressions were observed. Mothers of these infants displayed significantly less matching or imitation of their infant's facial expressions, showed random rather than contingent responsiveness to sadness, and a significant ignoring response to infant anger. These differences were attributed to differences in gazing patterns and negative emotion expression in preterm infants. The results are discussed within a framework of emotion socialization that recognizes bidirectionality of influence in the emotional patterns of mothers and infants. 相似文献

We studied individual differences in 3-month-olds' perceptions of smiling and the experiential correlates of those differences. In the laboratory, infants saw a graduated series of smiles that grew in intensity of expression. As a group, 3-month-olds preferred increasingly intense expressions of smiling, but individually they showed different growth rates of preference across the smiling series. Further, infants' preferences related to their home experiences: Infants who showed greater sensitivity to smiling had mothers who more frequently encouraged attention to themselves when they were smiling and their infants were looking at them. Infant discrimination within and between categories of facial expression and the relative strengths of association between different kinds of naturally occurring experiences and infant perceptual sensitivity are discussed. 相似文献

Six-month-old infants' ability to form an abstract category of containment was examined using a standard infant categorization task. Infants were habituated to 4 pairs of objects in a containment relation. Following habituation, infants were tested with a novel example of the familiar containment relation and an example of an unfamiliar relation. Results indicate that infants look reliably longer at the unfamiliar versus familiar relation, indicating that they can form a categorical representation of containment. A second experiment demonstrated that infants do not rely on object occlusion to discriminate containment from a support or a behind spatial relation. Together, the results indicate that by 6 months, infants can recognize a containment relation from different angles and across different pairs of objects. 相似文献
