We examined how infants’ attentional disengagement from happy, fearful, neutral, and phase-scrambled faces at 8 months, as assessed by eye tracking, is associated with trajectories of maternal depressive symptoms from early pregnancy to 6 months postpartum (decreasing n = 48, increasing n = 34, and consistently low symptom levels n = 280). The sample (mother–infant dyads belonging to a larger FinnBrain Birth Cohort Study) was collected between 5/2013–6/2016. The overall disengagement probability from faces to distractors was not related to maternal depressive symptoms, but fear bias was heightened in infants whose mothers reported decreasing or increasing depressive symptoms. Exacerbated attention to fearful faces in infants of mothers with depressive symptoms may be independent of the timing of the symptoms in the pre- and postnatal stages. 相似文献

2 experiments were conducted to examine 7-month-old infants' perception of the facial expressions happy and fear. Using a paired-comparison procedure, infants in the first experiment were able to generalize their discrimination of these 2 expressions across the faces of 4 male and female models if they were first presented with the set of happy faces, but not if they were first presented with the set of fear faces. A second experiment was conducted to examine the source of the stimulus presentation order effect. Here a second group of 7-month-old infants was presented with a single male or female face posing both the happy and fear expressions simultaneously. The results revealed significantly longer looking to the fear face. This preference to look at fear faces is discussed, as are its implications for studies of expression recognition in general. 相似文献

To investigate the role of early regulatory problems (RP), such as problems in feeding, sleeping, and calming down during later development, the association between parent-reported RP at 3 months (no-RP, n = 110; RP, n = 66) and attention to emotional faces at 8 months was studied. Eight-month-old infants had a strong tendency to look at faces and to specifically fearful faces, and the individual variance in this tendency was assessed with eye tracking using a face-distractor paradigm. The early RPs were related to a lower attention bias to fearful faces compared to happy and neutral faces after controlling for temperamental negative affectivity. This suggests that early RPs are related to the processing of emotional information later during infancy. 相似文献

Combined with emotional expressions, eye gaze can provide essential information to indicate threat in the environment. The current study assessed the effects of eye gaze direction on infants’ neural processing of fearful and angry faces. Event‐related potentials were recorded from thirteen 7‐month‐old infants. Two face‐sensitive posterior components, the N290 and P400, as well as a frontocentral negative component (Nc), indicating attentional arousal, were sensitive to eye gaze direction and emotion. A larger Nc was observed for angry faces with direct compared to averted eye gaze. Fearful faces elicited a larger N290 than angry faces, whereas angry faces elicited a more prominent P400 regardless of eye gaze direction. The findings are discussed in terms of early social cognitive and neural development. 相似文献

3 experiments examined 7-month-old infants' ability to discriminate the facial expressions of happy vs. fear. Experiment 1 revealed that infants demonstrated discrimination of happy vs. fear expressions when posed by a single model but that this discrimination was affected by the order of stimulus presentation. In experiment 2 infants were shown 2 models posing the happing and fearful expressions and did not demonstrate generalization of the discrimination of happy versus fear across these models. The third and main experiment varied the test procedure. Here, infants demonstrated reliable generalized discrimination of the 2 expressions across different models. As in experiment 1, however, these results were constrained by the order in which the stimuli were presented. These consistent order effects were not due to the initial salience of the 2 expressions but, instead, appeared to reflect differential rates of habituation to happy vs. fear expressions. 相似文献

Cognitive Brain Event-Related Potentials and Emotion Processing in Maltreated Children 总被引：1，自引：0，他引：1

Cognitive event-related potentials (ERPs) were recorded from 23 maltreated and 21 nonmaltreated children. Children were presented with slides of Ekman photographs of asingle model posing an angry (25%), a happy (25%), or a neutral (50%) facial expression. In 1 of 2 counterbalanced target conditions, children were asked to press a button in response to the angry face; in the other target condition, they responded to the happy face. Both samples, as expected, exhibited the largest amplitude of the P300 component of the ERP to target stimuli and the smallest amplitude to nontargets. For nonmaltreated children, the average amplitude of P300 across slides was comparable for the 2 target conditions. In contrast, maltreated children displaed larger P300 ampltude to stimuli when they were directed to attend to angry, as opposd children displayed larger p300 amplitude to stimuli whe they were directed to attend to angry, as opposed to happy, targets. These reaults suggest different cognitive processing for positive versus negative affective expressions by children with histories of atypical emotiaonal exotional experiences. 相似文献

Infants' Responses to Facial and Vocal Emotional Signals in a Social Referencing Paradigm 总被引：5，自引：0，他引：5
The independent effects of facial and vocal emotional signals and of positive and negative signals on infant behavior were investigated in a novel toy social referencing paradigm. 90 12-month-old infants and their mothers were assigned to an expression condition (neutral, happy, or fear) nested within a modality condition (face-only or voice-only). Each infant participated in 3 trials: a baseline trial, an expression trial, and a final positive trial. We found that fearful vocal emotional signals, when presented without facial signals, were sufficient to elicit appropriate behavior regulation. Infants in the fear-voice condition looked at their mothers longer, showed less toy proximity, and tended to show more negative affect than infants in the neutral-voice condition. Happy vocal signals did not elicit differential responding. The infants' sex was a factor in the few effects that were found for infants' responses to facial emotional signals. 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

Ninety 6- and 7-year-olds (49.3% White, mostly middle class) from greater Washington, DC were randomly assigned to a subliminal priming condition (secure, happy, or neutral) to determine if attachment security priming decreases physiological, expressive, and self-reported fear reactions to threatening stimuli. Dispositional attachment security was also assessed. Secure priming and attachment security each decreased electrodermal reactivity, increased vagal augmentation, and decreased fearful facial expressions compared to control conditions. Examination of a statistical interaction between security priming and child attachment indicated that, although secure children had increased vagal augmentation and fewer fearful expressions than insecure children, the effects of priming were constant across secure and insecure children. There were no priming or attachment effects associated with children's self-reported fear. 相似文献

Holistic face processing was investigated in newborns, 3-month-old infants, and adults through a modified version of the composite face paradigm and the recording of eye movements. After familiarization to the top portion of a face, participants (N = 70) were shown 2 aligned or misaligned faces, 1 of which comprised the familiar top part. In the aligned condition, no visual preference was found at any group age. In the misaligned condition, 3-month-olds preferred the face stimulus with the familiar top part, adults preferred the face stimulus with the novel one, and newborns did not manifest any visual preference. Results revealed that both infants' and adults' eye movements may be affected by holistic face information and demonstrated holistic face processing in 3-month-olds. 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 relation of positive affect to attention and learning was examined in 5-, 7-, and 9-month-olds (N = 84). Affect and attention were assessed while the infants inspected a photograph. Affect was rated globally, for overall mood, and specifically, for amount of time smiling. Attention was indexed by the duration of the infant's longest (or peak) look, a measure previously linked to differential cognitive performance. At all ages, positive affect (shown by approximately half the infants) was associated with long look durations and slower learning, as assessed on a task in which infants learned to distinguish a familiar face from a series of novel faces. By contrast, neutral affect was associated with short looks and faster learning. Affect and look duration had synergistic effects, in that learning was faster than expected for infants who displayed both short looks and neutral affect. These findings are compatible with adult research that links positive affect to less analytical processing, and provide the first evidence that affect may be associated with the speed of processing differences implicated in short and long looking. 相似文献

A novel method was used to investigate developmental changes in face processing: attractiveness aftereffects. Consistent with the norm-based coding model, viewing consistently distorted faces shifts adults' attractiveness preferences toward the adapting stimuli. Thus, adults' attractiveness judgments are influenced by a continuously updated face prototype. To investigate the development of this process, a novel method was developed for 8-year-olds. After reading a storybook composed of faces with either compressed or expanded features, 8-year-olds' ratings of faces distorted in the direction of the adapting stimuli increased. Nonetheless, they required larger distortions than adults to rate undistorted faces as most attractive preadaptation. Thus, although 8-year-olds' attractiveness preferences are influenced by a continuously updated prototype, their face space is less refined than that of adults. 相似文献

A growing body of research indicates connections exist between action, perception, and cognition in infants. In this study, associated changes between sitting ability and upright face processing were tested in 111 infants. Using the visual habituation “switch” task (C. H. Cashon & L. B. Cohen, 2004; L. B. Cohen & C. H. Cashon, 2001), holistic processing of faces was assessed in same‐aged non‐ and near sitters (22–25 weeks) and same‐aged new and expert sitters (27–32 weeks). U‐shaped relation was found between sitting stage and holistic face processing such that only nonsitters and expert sitters processed faces holistically. It is posited that the results are due to a reorganization of the upright face‐processing system resulting from infants' learning to sit independently and trying to incorporate the meaning of upright faces. 相似文献

The current study investigated factors thought to contribute to facial emotion processing. Female university students (N = 126) completed self-report measures of childhood emotional maltreatment, anxiety symptoms, attachment anxiety and avoidance, and trait mindfulness before completing a facial emotion recognition task, where they viewed sequences of faces that incorporated progressively more emotional content until they were able to correctly identify the emotion. They completed the task under low and high cognitive load conditions to distinguish between relatively effortful versus automatic processing abilities. Regression analyses revealed that under low cognitive load, attachment avoidance and mindfulness predicted quicker identification of fear (i.e., with less perceptual information), whereas anxiety predicted slower identification of fear (i.e., with more perceptual information). In the high cognitive load condition, emotional maltreatment and mindfulness predicted quicker identification of fear, and anxiety and mindfulness predicted faster identification of emotions overall. Although current findings are correlational, most of these effects were specific to fearful faces, suggesting that experiences of childhood emotional maltreatment and associated socio-emotional sequelae are related to heightened processing of threat-related information. 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

The present experiment examined the degree to which analytic and holistic modes of processing play a role in the way children and adults categorize upright and inverted faces. Seven-year-old children (n = 38), 10-year-old children (n = 40), and adults (n = 55) were instructed to classify upright and inverted faces into two categories. The construction of the categories allowed participants to categorize the faces either analytically (by focusing on a single attribute) or holistically (in terms of overall similarity). The results show both a developmental trend from analytic to holistic processing and an effect of face inversion with increasing age. Thus, it appears that 7-year-old children process upright and inverted faces in a way comparable to their processing of nonfacial visual stimuli, namely analytically, whereas a growing proportion of 10-year-olds and adults process only upright faces holistically by adopting a specific mode of face processing. 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

Event-related Potentials in Year-Old Infants: Relations with Emotionality and Cortisol 总被引：2，自引：0，他引：2
Event-related po-potentials (ERPs) were recorded from year-old infants presented with sets of familiar faces presented frequently and infrequently, and a set of novel faces presented infrequently. The normative response of infants in this sample was a late positive slow wave to the Infrequent Familiar faces, and a return to baseline to the Frequent Familiar and Infrequent Novel faces (although there was a tendency for some infants to show a positive slow wave to the latter events). A factor score based on data from frontal and central leads that reflected this normative pattern was significantly associated with infant emotional behavior and cortisol. Infants scoring higher on the normative ERP factor were more distressed during separation, were reported by their parents to smile and laugh more, and had lower cortisol concentrations during ERP testing. These data were interpreted as reflecting the coordination of adaptive responding among different physiological and behavioral systems. 相似文献

We measured event-related potentials (ERPs) to synthetic consonant-vowel syllables (/ba/, /da/, /ga/) from 26 newborns with familial risk for dyslexia and 23 control infants participating in the Jyv?skyl? Longitudinal Study of Dyslexia. The syllables were presented with equal probability and with interstimulus intervals ranging from 3,010 to 7,285 ms. Analyses of averaged ERPs from the latencies identified on the basis of principal component analysis (PCA) revealed significant group differences in stop-consonant processing in several latency ranges. At the latencies of 50-170 ms and 540-630 ms, the responses to /ga/ were larger and more positive than those to /ba/ and /da/ in the right hemisphere in the at-risk group. Between 740 and 940 ms, the responses to /ba/ and /da/ differed between anterior and posterior electrode sites in the control group. These results indicate that the cortical electric activation evoked by speech elements differs between children with and without risk for dyslexia even immediately after birth. Group-related effects at early and late latency ranges of ERPs suggest differences both in the early sound processing based on activation of afferent elements and in later phases of syllable encoding. 相似文献
