The current four experiments investigated gaze following behavior in response to gaze and head turns in 4-month-olds and how reinforcement learning influences this behavior (N = 99). Using interactive eye tracking, infants’ gaze elicited an animation whenever infants followed a person’s head or gaze orientation (Experiment 1.1, 2.1 and 2.2) or looked at the opposite side (Experiment 1.2). Infants spontaneously followed the direction of a turning head with and without simultaneously shifted gaze direction (Cohen’s d: 0.93–1.05) but not the direction of isolated gaze shifts. We only found a weak effect of reinforcement on gaze following in one of the four experiments. Results will be discussed with regard to the impact of reinforcement on the maintenance of already existing gaze following behavior. 相似文献

孤独症儿童对社会刺激的注意行为存在缺陷,主要表现在对眼睛注视的定向注意和联合注意受损。回溯研究发现,孤独症儿童在婴儿期就表现出对社会刺激如面孔、名字等的注意损伤。然而采用空间注意线索化范式,发现既有证据表明他们能对眼睛注视线索发出注意定向行为,也有相反的证据。孤独症儿童联合注意的缺损主要表现在,不能对他人的社会指向做出反应,也不能主动发出注意分享行为。文章回顾了孤独症儿童对眼睛注视线索引起的注意定向的研究,分析了结果存在矛盾的可能原因,列举了他们在联合注意缺损上的主要表现,并总结了与其社会性注意相关神经基础的异常。 相似文献

Young infants are sensitive to self‐directed social actions, but do they appreciate the intentional, target‐directed nature of such behaviors? The authors addressed this question by investigating infants’ understanding of social gaze in third‐party interactions (N = 104). Ten‐month‐old infants discriminated between 2 people in mutual versus averted gaze, and expected a person to look at her social partner during conversation. In contrast, 9‐month‐old infants showed neither ability, even when provided with information that highlighted the gazer’s social goals. These results indicate considerable improvement in infants’ abilities to analyze the social gaze of others toward the end of their 1st year, which may relate to their appreciation of gaze as both a social and goal‐directed action. 相似文献

The importance of eye gaze as a means of communication is indisputable. However, there is debate about whether there is a dedicated neural module, which functions as an eye gaze detector and when infants are able to use eye gaze cues in a referential way. The application of neuroscience methodologies to developmental psychology has provided new insights into early social cognitive development. This review integrates findings on the development of eye gaze processing with research on the neural mechanisms underlying infant and adult social cognition. This research shows how a cognitive neuroscience approach can improve our understanding of social development and autism spectrum disorder. 相似文献

To examine the ontogeny of emotional face processing, event-related potentials (ERPs) were recorded from adults and 7-month-old infants while viewing pictures of fearful, happy, and neutral faces. Face-sensitive ERPs at occipital-temporal scalp regions differentiated between fearful and neutral/happy faces in both adults (N170 was larger for fear) and infants (P400 was larger for fear). Behavioral measures showed no overt attentional bias toward fearful faces in adults, but in infants, the duration of the first fixation was longer for fearful than happy faces. Together, these results suggest that the neural systems underlying the differential processing of fearful and happy/neutral faces are functional early in life, and that affective factors may play an important role in modulating infants' face processing. 相似文献

This study utilized electroencephalographic recordings to examine whether young children with autism spectrum disorder (ASD) have impaired face recognition ability. High-density brain event-related potentials (ERPs) were recorded to photos of the child's mother's face versus an unfamiliar female face and photos of a favorite versus an unfamiliar toy from children with ASD, children with typical development, and children with developmental delay, all 3 to 4 years of age (N = 118). Typically developing children showed ERP amplitude differences in two components, P400 and Nc, to a familiar versus an unfamiliar face, and to a familiar versus an unfamiliar object. In contrast, children with ASD failed to show differences in ERPs to a familiar versus an unfamiliar face, but they did show P400 and Nc amplitude differences to a familiar versus an unfamiliar object. Developmentally delayed children showed significant ERP amplitude differences for the positive slow wave for both faces and objects. These data suggest that autism is associated with face recognition impairment that is manifest early in life. 相似文献

Infants become sensitive to emotion expressions early in the 1st year and such sensitivity is likely crucial for social development and adaptation. Social interactions with primary caregivers may play a key role in the development of this complex ability. This study aimed to investigate how variations in parenting behavior affect infants' neural responses to emotional faces. Event‐related potentials (ERPs) to emotional faces were recorded from 40 healthy 7‐month‐old infants (24 males). Parental behavior was assessed and coded using the Emotional Availability Scales during free‐play interaction. Sensitive parenting was associated with increased amplitudes to positive facial expressions on the face‐sensitive ERP component, the negative central. Findings are discussed in relation to the interactive mechanisms influencing how infants neurally encode positive emotions. 相似文献

How does visual experience change over development? To investigate changes in visual input over the developmental transition from crawling to walking, thirty 13‐month‐olds crawled or walked down a straight path wearing a head‐mounted eye tracker that recorded gaze direction and head‐centered field of view. Thirteen additional infants wore a motion tracker that recorded head orientation. Compared to walkers, crawlers' field of view contained less walls and more floor. Walkers directed gaze straight ahead at caregivers, whereas crawlers looked down at the floor. Crawlers obtained visual information about targets at higher elevations—caregivers and toys—by craning their heads upward and sitting up to bring the room into view. Findings indicate that visual experiences are intimately tied to infants' posture. 相似文献

Differential experience leads infants to have perceptual processing advantages for own‐ over other‐race faces, but whether this experience has downstream consequences is unknown. Three experiments examined whether 7‐month‐olds (range = 5.9–8.5 months; N = 96) use gaze from own‐ versus other‐race adults to anticipate events. When gaze predicted an event's occurrence with 100% reliability, 7‐month‐olds followed both adults equally; with 25% (chance) reliability, neither was followed. However, with 50% (uncertain) reliability, infants followed own‐ over other‐race gaze. Differential face race experience may thus affect how infants use social cues from own‐ versus other‐race adults for learning. Such findings suggest that infants integrate online statistical reliability information with prior knowledge of own versus other race to guide social interaction and learning. 相似文献

Despite hundreds of studies describing infants' visual exploration of experimental stimuli, researchers know little about where infants look during everyday interactions. The current study describes the first method for studying visual behavior during natural interactions in mobile infants. Six 14-month-old infants wore a head-mounted eye-tracker that recorded gaze during free play with mothers. Results revealed that infants' visual exploration is opportunistic and depends on the availability of information and the constraints of infants' own bodies. Looks to mothers' faces were rare following infant-directed utterances but more likely if mothers were sitting at infants' eye level. Gaze toward the destination of infants' hand movements was common during manual actions and crawling, but looks toward obstacles during leg movements were less frequent. 相似文献

Two experiments examined the effects of a pedagogical agent's (PA's) pointing gestures, eye gaze, and eye contact on learning processes (measured by learners' eye fixations on relevant elements) and learning outcomes (as measured by retention and transfer test scores) with a multimedia lesson on neural transmission. In Experiment 1, having the PA look at and point to relevant elements as she lectured led to more eye fixations on the relevant portion of the graphic and better retention and transfer test scores. Keeping eye contact with learners tended to improve retention test scores and increased their eye fixations on relevant elements when the PA also looked at and pointed to the graphic. In Experiment 2, the PA's pointing gestures as a stand-alone feature caused better retention test scores and more fixations on relevant elements of the graphic, but eye gaze direction did not. These findings help extend the embodiment principle. 相似文献

Adults recognize emotions conveyed by bodies with comparable accuracy to facial emotions. However, no prior study has explored infants' perception of body emotions. In Experiment 1, 6.5‐month‐olds (n = 32) preferred happy over neutral actions of actors with covered faces in upright but not inverted silent videos. In Experiment 2, infants (n = 32) matched happy and angry videos to corresponding vocalizations when the videos were upright but not when they were inverted. Experiment 3 (n = 16) demonstrated that infants' performance in Experiment 2 was not driven by information from the covered face and head. Thus, young infants are sensitive to emotions conveyed by bodies and match them to affective vocalizations, indicating sophisticated emotion processing capabilities early in life. 相似文献

The present article shows that infant and dyad differences in hand–eye coordination predict dyad differences in joint attention (JA). In the study reported here, 51 toddlers ranging in age from 11 to 24 months and their parents wore head‐mounted eye trackers as they played with objects together. We found that physically active toddlers aligned their looking behavior with their parent and achieved a substantial proportion of time spent jointly attending to the same object. However, JA did not arise through gaze following but rather through the coordination of gaze with manual actions on objects as both infants and parents attended to their partner's object manipulations. Moreover, dyad differences in JA were associated with dyad differences in hand following. 相似文献

Automatic attention cueing by perceived changes in gaze direction was studied in 2-year-old children with autism and typically developing (TD) controls using a visual attention cueing paradigm. In Experiments 1 and 2 the cue consisted of an eye movement (Eyes) and a nonbiological movement (SimEyes), respectively. The results suggest that visual attention in children with autism and their TD counterparts is cued by perceived eye movement. Thus, although in naturalistic situations toddlers with autism do not follow the gaze of others, they are sensitive to directional cues inherent in eye movement. Cue-specific differences in performance related to the level of engagement and cue-processing time may suggest reliance on different underlying strategies for gaze processing in autism. 相似文献

Infant Sensitivity to Adult Eye Direction 总被引：5，自引：0，他引：5
Adult eye direction was manipulated while adults interacted with 3–6-month-olds over closed-circuit television (Experiment 1) or in person (Experiment 2). Infants received 4 1-min interaction periods. For experimental groups, adult eye contact was maintained during Periods 1 and 3, and averted during Periods 2 and 4 (by viewing infants on a television monitor to maintain contingency). Control infants received eye contact during all periods. Experimental infants' smiling declined whenever adults looked away; their visual attention simply decreased across periods. Control infants showed little change in gaze or smiling across periods. The implications of these results for Baron-Cohen's model of infant theory of mind and Morton and Johnson's 2-process theory of infant face perception are discussed. 相似文献

This study examined the transactional interplay among children's negative family representations, visual processing of negative emotions, and externalizing symptoms in a sample of 243 preschool children (Mage = 4.60 years). Children participated in three annual measurement occasions. Cross‐lagged autoregressive models were conducted with multimethod, multi‐informant data to identify mediational pathways. Consistent with schema‐based top‐down models, negative family representations were associated with attention to negative faces in an eye‐tracking task and their externalizing symptoms. Children's negative representations of family relationships specifically predicted decreases in their attention to negative emotions, which, in turn, was associated with subsequent increases in their externalizing symptoms. Follow‐up analyses indicated that the mediational role of diminished attention to negative emotions was particularly pronounced for angry faces. 相似文献

We examined the ontogeny of the infant rhesus monkey's defensive behaviors and the ability to modulate them in response to specific environmental cues. Rhesus infants in 4 age groups (N = 8 per group) were briefly separated from their mothers and tested under 3 conditions: alone, in the presence of a human who averted his gaze, and in the presence of a human staring at them. Infants as young as 0 to 2 weeks displayed defensive behaviors but did not selectively respond to the human's presence or direction of gaze. By 9 to 12 weeks of age, infants modulated their responses in relation to the parameters of the threat. At this age, infant rhesus monkeys undergo cognitive and emotional changes associated with brain development similar to those in human infants 7 to 12 months old. This also is the time when human infants engage in complex emotional and behavioral responses to threatening situations. Understanding the development and expression of defensive behaviors in infant monkeys should be applicable to similar issues in emotional development of human infants. 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

Do infants see emotional expressions in static faces? 总被引：2，自引：0，他引：2
To determine whether young infants discriminate photographs of different emotions on an affect-relevant basis or on the basis of isolated features unrelated to emotion, groups of 17-, 23-, and 29-week-olds were habituated to slides of 8 women posing either Toothy Angry, Nontoothy Angry, or Nontoothy Smiling facial expressions and were then shown 2 new women in the familiarized expression and in a novel Toothy Smiling expression. At all 3 ages, recovery to the novel Toothy Smiling faces occurred only after habituation to Nontoothy faces (whether smiling or angry), not after habituation to Toothy Angry faces, indicating that infants had been responsive to nonspecific features of the photographs (presence or absence of bared teeth) rather than to affectively relevant configurations of features. In a second experiment, 2 older age groups (35 and 41 weeks) also proved to be insensitive to affect-related aspects of still faces, though more so for angry than for happy expressions. It is suggested that the young infant's difficulty in extracting emotional information from static stimuli may be attributable to the absence of the critical invariants (dynamic, multimodally specified) that characterize naturalistic expressions of emotion. 相似文献
