The relation between adult perception of emotion intensity in the cries of 1- and 6-month-old infants and the acoustic characteristics of the cries was examined. In the first study, adults who were inexperienced in child care rated 40 cries on 3 emotion intensity scales: anger, fear, and distress. The cries of 6-month-olds were rated as being significantly more intense. Different acoustic variables accounted for emotion intensity ratings for the 2 infant ages. Peak amplitude and noisiness of the cry predicted adult judgments of intensity ratings of 1-month-olds' cries; a measure of amplitude ratio (in 2 frequency bands) was the best predictor of intensity ratings of 6-month-olds' cries. In the second study, parents of infants rated the same cries on the same scales. They also rated the older infants' cries as being more intense. The 2 adult groups did not differ on their ratings, and a regression equation derived from one adult group predicted the other adult group's rating of the same infant age better than it predicted its own ratings for the other infant age. Infant age, and its associated acoustic features, seems to be a more important determinant of adults' perception of emotion intensity than are such adult characteristics as gender or infant-care experience.  相似文献

3 studies were designed to examine the "still-face" paradigm, in which mothers stared at their 3- or 6-month-olds for a brief, still-face period interposed between 2 periods of normal face-to-face interaction. 6-month-olds decreased smiling and gazing at their mothers and grimaced more during the still-face period relative to the other periods; no period effects occurred in a no-change control group (Studies 1 and 2). Similar results were obtained when mothers and their infants observed and interacted with each other over closed-circuit color television monitors (Study 3). Moreover, the same relative decline in the infants' visual attention and positive affect during the still-face period occurred to a change in mothers' facial display (a televised, prerecorded, still face vs. a televised, live, interacting face) regardless of the presence or absence of their interactive voices (sound on the infants' monitor turned on or off). 3-month-olds exhibited a significant still-face effect, but only when maternal touch was a part of the manipulation (Study 1 vs. 2); therefore, the televised procedure was not conducted. The still-face effect is a robust phenomenon, produced with either "live" or "televised" procedures, both of which offer promising techniques for examining models of socioemotional perception/understanding of infants.  相似文献

This study examined reactions of 1-year-olds and young 2-year-olds to being controlled by mothers. Mothers' supportive behavior predicted children's willing compliance. However, contrary to research with older children, defiance was also associated with variables linked to maternal competence, specifically, mothers' supportive behavior, autonomy-granting controls, and low depressive symptoms. At this age high-defiant children initiated positive interaction with mothers more than did low-defiant children. With age, children displayed more willing compliance and more active resistance (defiance, low passivity). However, developmental increases in active resistance were absent when mothers were high in depressive symptoms. Findings are consistent with the proposal that in early development active resistance to parents often reflects children's motivation to control events, not poor parenting or strained parent-child relationships.  相似文献

One of the major adaptations during the infancy period is the development of the ability to cope with arousing or uncertain events. The following study was designed to examine emotion regulation strategy use between 6 and 18 months. 75 infants (25 each of 6-, 12-, and 18-month-olds) were videotaped interacting with 3 female strangers. Coping strategies were coded using a portable computer with a continuous sampling program, enabling coders to record both frequencies and durations of behaviors. Results indicated that 6-month-olds were more likely than 12- or 18-month-olds to use gaze aversion and fussing as their primary emotion regulation strategies, and were less likely than the older infants to use self-soothing and self-distraction. 18-month-olds were more likely than the younger infants to attempt to direct their interactions with the strangers. Infants' strategy use also differed as a function of their wariness of strangers, particularly at 12 months of age.  相似文献

Self-report and behavioral observation procedures were used to assess the quality of mothers' interactions with facially deformed infants. This assessment strategy also provided an opportunity to evaluate the hypothesis that parents of facially deformed infants may deny or be unaware of deficits in their relationships with these children. 10 mothers, 5 with unattractive/craniofacially deformed infants and 5 with normal infants, completed self-report measures of stress, social support, satisfaction with parenting, and general life satisfaction. Mother-infant interactions were videotaped and rated on discrete and global behavioral measures. Results revealed that mothers of deformed infants rated their parental satisfaction and current life satisfaction more positively than did mothers of normal infants. However, these same mothers were observed to behave in a consistently less nurturant manner than mothers of normal children. These results suggest that infant facial deformity/unattractiveness may affect the quality of infant-caregiver interactions without parental awareness.  相似文献

The development of volitional emotion regulation of expression was examined with a modified disappointing gift paradigm and strategy for coding children's expressions. Forty‐nine boys and 49 girls aged 4, 6, and 8 were motivated to volitionally deceive an observer by false smiling, regardless of whether they received an attractive, unattractive, or no gift. Ten naïve observers watched children's videotaped behavior in random order and judged the quality of emotion and type of gift. This impression analysis indicated that children's competence to volitionally regulate their expressions increased with age. In addition, this ability was positively associated with children's emotion understanding of how to differentiate between emotion and expression. Unexpectedly, girls did not display a superior volitional regulation of expression than boys.  相似文献

The purpose of this experiment was to measure the effects of source physical attractiveness and receiver Machiavellian tendency on receiver attitude change. Subjects were asked to read a persuasive message written by a physically attractive or unattractive source. High and low Machiavellian subjects were randomly assigned to the two attractiveness conditions. Pre‐ and post‐manipulation measures were made to assess attitudes toward the persuasive message. A significant attractiveness effect was obtained—the attractive source being found more persuasive. Moreover, a significant Machiavellian × attractiveness interaction effect was obtained. While low‐Machiavellian subjects were greatly influenced by the attractive source, high Machiavellians were not.  相似文献

24 infants, 12 4-month-olds and 12 6-month-olds, were repeatedly shown slides of 3 facial expressions. The expressions were previously judged by obervers to be indicators of joy, anger, and no emotion, respectively. The duration of the first visual fixation to each presentation of the slides was monitored for each subject. The data indicated that the infants looked at the joy expression significantly more than at either the anger or neutral expressions. The results suggest that infants are capable of discriminating emotion expressions earlier in their development than previous studies have implied.  相似文献

The birth of words: ten-month-olds learn words through perceptual salience   总被引：1，自引：0，他引：1  
A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a particular spatial location rather than to an object. Results show that 10-month-olds can learn new labels and do so by relying on the perceptual salience of an object instead of social cues provided by a speaker. This is in direct contrast to the way in which older children (12-, 18-, and 24-month-olds) learn and extend new object names.  相似文献

To determine whether the "depressed" behavior (e.g., less positive affect and lower activity level) of infants noted during interactions with their "depressed" mothers generalizes to their interactions with nondepressed adults, 74 3-6-month-old infants of "depressed" and nondepressed mothers were videotaped in face-to-face interactions with their mothers and with nondepressed female strangers. "Depressed" mothers and their infants received lower ratings on all behaviors than nondepressed mothers and infants. Although the infants of "depressed" versus nondepressed mothers also received lower ratings with the stranger adult, very few differences were noted between those infants' ratings when interacting with their mother versus the stranger, suggesting that their "depressed" style of interacting is not specific to their interactions with depressed mothers but generalizes to their interactions with nondepressed adults as early as 3 months of age.  相似文献

This study investigated the effect of increasing familiarization time on the visual recognition memory of 6- and 12-month-old full-term and preterm infants. Infants were given trials in which they viewed a shape for either 10-, 15-, 20-, or 30-sec familiarization and were then tested for visual recognition memory using the paired comparison technique. While the older infants showed evidence of recognition memory after less familiarization time than the younger ones, at both ages preterms required considerably longer familiarization than full-terms. The pattern of performance replicates our earlier finding of developmental lags in the visual information processing of 6-month-old preterms and extends these findings to 12-month-olds. These results suggest that there are persistent differences between preterm and full-term infants throughout at least the first year of life in this very fundamental aspect of cognition.  相似文献

Despite dramatic increases in recent decades in the number of employed mothers with children under 3 years of age and the greater utilization of nonmaternal child-care services (particularly unregulated family day care), little is known about the nature and quality of care provided to these infants by their employed mothers and substitute caregivers. This study was conducted to provide a comparative assessment of maternal and nonmaternal infant caregiving practices in own-home and unregulated family day-care homes, respectively. 30 caregivers (10 employed mothers, 10 substitute caregivers, and 10 nonemployed mothers) were observed in interaction with 5-6-month-old infants using Yarrow, Rubenstein, and Pedersen's Home Environment and Mother-Infant Interaction scales. While no differences were observed in the caregiving of employed and nonemployed mothers, both of these groups exceeded the sitters in socially mediated stimulation, contingent responsiveness, positive affect, and overall level and variety of social stimulation. In addition, employed mothers provided more tactile-kinesthetic, visual, and auditory stimulation to their infants than did the substitute caregivers. However, no differences were found between the infants reared in the home and day-care settings in Bayley Mental and Psychomotor developmental abilities. Evidence implicated group size (total number of children) in the quality of caregiving in family day-care homes. The impact of daily separations and qualitatively different caregiving experiences on infants is discussed.  相似文献

This article presents the results of a study comparing deaf and hearing parents in the use of visual-tactile communication strategies during interaction with their hearing-impaired children between 18 and 24 months of age. The study includes 17 deaf and hard-of-hearing children and 33 parents, covering hearing mothers (n = 12), hearing fathers (n = 11), deaf mothers (n = 5), and deaf fathers (n = 5). The four groups of parents are compared in the use of visual-tactile communication strategies during free play with their children. Overall results show that deaf mothers and deaf fathers differ significantly from hearing parents in the use of a visual communication style adapted to the developmental communication needs and abilities related to the 18- to 24-month age period. The study pays special attention to differences in visual-tactile communication strategies according to hearing status, gender, use of languages, and communication modes.  相似文献

The ability to use the relations between visible landmarks to locate nonvisible goals (allocentric spatial coding) underlies success on a variety of everyday spatial orientation problems. Little is known about the development of true relational coding in infancy. Ninety-six 6-, 8.5- and 12-month-old infants were observed in a peekaboo paradigm in which they had to turn to a target location after displacement to a novel position and direction of facing. In a landmark condition, the target position was located between two landmarks, contrasted with a control condition in which no distinctive landmarks were provided. Six-month-old infants performed poorly in both conditions, 8.5-month-olds were significantly better with the landmarks, and 12-month-olds solved the task with or without landmarks. A follow-up study confirmed that the 8.5-month-olds used both landmarks to solve the task. This demonstration of allocentric spatial coding in 8.5-month-old infants shows earlier competence than that found in previous work in which only infants at the end of the first year were able to use landmarks relationally.  相似文献

6 1-month-old infants and 6 2-month-old infants each viewed 3 faces (his mother's, a strange woman's, and a strange man's) while his eye movements were recorded by corneal photography. The 1-month-olds fixated away from the faces most of the time, and they looked at their mothers even less often than at the strangers. When they did fixate a face, they usually chose a limited portion of the perimeter. By constrast, 2-month-olds fixated the faces most of the time, looked at more features, and were more likely to look at internal features, especially the eyes. This scanning resembles that reported previously for 2-dimensional shapes, although in some respects it appears unique to faces.  相似文献

This study examined infant response and recovery from a social challenge and parent responses. Behavioral and physiological responses were measured from forty-three 5- and 6-month-olds infants during a modified still-face procedure that used an additional still-face reunion sequence. Results confirm the hypothesis that infants of more responsive parents show more regulation than infants of less responsive parents. Infants of more responsive parents showed greater regulation of heart rate and negative affect during the final episode of the procedure than infants of less responsive parents. In addition, this procedure elicited a cortisol response (from .22 microg/dl to .31 microg/dl). Findings suggest important links between parent behavior and infant stress reactivity and regulation.  相似文献

The development of social referencing   总被引：6，自引：0，他引：6  
The development of social referencing in 40 infants aged 6-9, 10-13, and 14-22 months was investigated in this study. Social referencing was defined broadly to include children's looks toward parents, their instrumental toy behaviors, affective expressions, and other behaviors toward parents. Children's looks at parents were more selective with increasing age, with older infants preferring to look directly at their parents' faces and younger infants showing no preference for looks to faces over looks elsewhere at the parent. Younger infants looked most often when their parents expressed positive affect, whereas older infants looked most often when parents displayed fearful reactions toward a stimulus. Evidence of a behavioral regulatory effect on instrumental toy behaviors was found only among infants 10-13 months of age. However, only infants older than 14 months of age inhibited touching the toy until after referencing the parent. On some measures these older infants showed a preference for toys associated with fearful messages. Affective expressions were in line with positive and negative behavior toward toys. No support for mood modification or simple imitation as explanations for the effects was found. Results indicated that the looking behavior of younger children may function differently than that of older children, and that social referencing involves a number of component skills that develop during the end of the first year and throughout the second year of life.  相似文献

The current study investigated whether individual and developmental differences in look duration are correlated with the latency for infants to disengage fixation from a visual stimulus. Ninety-four infants (52 3-month-olds, 42 4-month-olds) were tested in a procedure that measured ocular reaction time to shift fixation from a central target to a peripheral target under conditions in which the central-target either remained present ("competition" condition) or was removed from the display ("noncompetition" condition). Look duration was correlated with disengagement latency; longer-looking infants were slower than shorter-looking infants to shift fixation to the peripheral target on competition trials, but not noncompetition trials. Results were similar for 3- and 4-month-olds, although 3-month-olds showed slower latencies on all trials. Furthermore, long-looking infants were not consistently slower, but rather showed greater variability in their response latencies under conditions that required disengagement of fixation. The results support the position that developmental and individual differences in look duration are linked to the development of the neural attentional systems that control the ability to disengage, or inhibit, visual fixation.  相似文献

Adolescent-era predictors of adult romantic life satisfaction were examined in a multimethod, prospective, longitudinal study of 165 adolescents followed from ages 13 to 30. Progress in key developmental tasks, including establishing positive expectations and capacity for assertiveness with peers at age 13, social competence at ages 15 and 16, and ability to form and maintain strong close friendships at ages 16–18, predicted romantic life satisfaction at ages 27–30. In contrast, several qualities linked to romantic experience during adolescence (i.e., sexual and dating experience, physical attractiveness) were unrelated to future satisfaction. Results suggest a central role of competence in nonromantic friendships as preparation for successful management of the future demands of adult romantic life.  相似文献

The goal of this investigation was to study the regulatory retention effects of an adult's emotional displays on infant behavior. In Study 1, 11- and 14-month-old infants were tested in a social-referencing-like paradigm in which a 1-hr delay was imposed between the exposure trials and the test trial. In Study 2, 11-month-olds were tested in the same paradigm, but the delay between the exposure trials and the test trial was only 3 min. Study 1 revealed that 14-month-olds, but not 11-month-olds, demonstrated behavior regulatory effects toward the target object linked to the adult's emotional displays. Study 2 indicated that 11-month-olds were affected by the emotional displays if the delay between exposure and test trials was brief enough.  相似文献
