This study examined whether young children are able to imitate a robot's goal‐directed actions. Children (24–35 months old) viewed videos showing a robot attempting to manipulate an object (e.g., putting beads inside a cup) but failing to achieve its goal (e.g., beads fell outside the cup). In 1 video, the robot made eye contact with a human before and after it failed the action. In another video, the robot did not make eye contact with the human adult. Only in the former condition did children “imitate” the robot's “intended” but unconsummated actions (e.g., putting beads inside a cup). When the robot did not make eye contact, children performed poorly, at the baseline level. These results suggest that human‐like gaze behaviors, not human‐like morphology, may play an important role in young children's imitation of a nonhuman agent's goal‐directed behaviors.  相似文献

Infants can infer agents’ goals after observing agents’ goal‐directed actions on objects and can subsequently make predictions about how agents will act on objects in the future. We investigated the representations supporting these predictions. We familiarized 6‐month‐old infants to an agent who preferentially reached for one of two featurally distinct objects following a cue. At test, the objects were sequentially occluded from the infant in the agent's presence. We asked whether infants could generate action predictions without visual access to the relevant objects by measuring whether infants shifted their gaze to the location of the agent's hidden goal object following the cue. We also examined what infants represented about the hidden objects by removing one of the occluders to reveal either the original hidden object or the unexpected other object and measuring infants’ looking time. We found that, even without visual access to the objects, infants made predictive gazes to the location of the agent's occluded goal object, but failed to represent the features of either hidden object. These results suggest that infants make goal‐based action predictions when the relevant objects in the scene are occluded, but doing so may come at the expense of maintaining representations of the objects.  相似文献

Three studies investigated the role of surface attributes in infants' identification of agents, using a habituation paradigm designed to tap infants' interpretation of grasping as goal directed (Woodward, 1998). When they viewed a bare human hand grasping objects, 7‐ and 12‐month‐old infants focused on the relation between the hand and its goal. When the surface properties of the hand were obscured by a glove, however, neither 7‐ nor 12‐month‐old infants represented its actions as goal directed (Study 1). Next, infants were shown that the gloved hands were part of a person either prior to (Study 2) or during (Study 3) the habituation procedure. Infants who actively monitored the gloved person in Study 2 and older infants in Study 3 interpreted the gloved reaches as goal directed. Thus, varying the extent to which an entity is identifiable as a person impacts infants' interpretation of the entity as an agent.  相似文献

The ability to effectively regulate emotions is an important marker for early socio‐emotional development. The uses of self‐comforting behaviors and self‐distraction have been empirically supported as effective regulatory strategies for infants, although research on determinants of such behaviors is scarce. Thus, a more thorough examination of the development of regulatory behaviors is needed. For the current study, 135 mothers, fathers, and their infants participated in laboratory visits at 3, 5, and 7 months of age where parent sensitivity and infant regulatory strategies were coded from the Still‐Face Paradigm. Parents also filled out questionnaires about infant temperament and parental involvement. Using multilevel modeling to examine levels and trajectories of self‐comforting and self‐distraction, the current study found: (1) infants higher in temperamental surgency used more self‐distraction and self‐comforting, (2) infants lower in surgency with highly involved parents increased in self‐distraction at a faster rate, particularly with highly involved fathers, and (3) infants used self‐comforting more than average with fathers when the infant was also lower in temperamental regulation. In addition, we examined trajectories of parent involvement and temperament in relation to infant regulatory strategy.  相似文献

Much has been written about the systemic effects of families and culture on individual well‐being. Seldom discussed, however, are the systemic effects of our relationship with the larger ecological system in which all families and cultures are embedded. A case is made for the importance of nature in family therapy. Furthermore, before therapists can effectively address ecological issues in therapy, they need to address various ecological self‐of‐the‐therapist issues that will influence their clinical practice. A series of questions are asked to help guide therapists in this exploration, and practical suggestions for incorporating nature into MFT clinical practice, training, and research are made.  相似文献

When mothers engage in infant‐directed (ID) speech, their voices change in a number of characteristic ways, including adopting a higher overall pitch. Studies have examined these acoustical cues and have tested infants' preferences for ID speech. However, little is known about how these cues change with maternal sensitivity to infant feedback in the context of interaction. In this study, each mother watched her infant (located in an adjacent sound booth) on a video screen and talked to him or her through a microphone. The mother believed that her infant could hear her voice and she attempted to make her infant happy through her vocalizations. In reality, the infant could not hear her voice. The mother's ID speech was analyzed in real time for changes in mean pitch. For half of the infant–mother dyads an experimenter surreptitiously positively engaged the infant when the voice analysis revealed a rise in pitch, thereby producing positive reinforcement to the mother for natural higher pitched ID speech. The other half were reinforced for lower pitched ID speech. Mothers raised their pitch significantly more in the former than the latter condition, illustrating that the pitch of ID speech is dynamically affected by feedback from the infant.  相似文献

Cultural variation in durations, relations, and contingencies of mother–infant person‐and object‐directed behaviors were examined for 121 nonmigrant Latino mother–infant dyads in South America, Latina immigrants from South America and their infants living in the United States, and European American mother–infant dyads. Nonmigrant Latina mothers and infants engaged in person‐directed behaviors longer than Latino immigrant or European American mothers and infants. Mother and infant person‐directed behaviors were positively related; mother and infant object‐related behaviors were related for some cultural groups but not others. Nearly all mother and infant behaviors were mutually contingent. Mothers were more responsive to infants' behaviors than infants were to mothers. Some cultural differences in responsiveness emerged. Immigrant status has a differentiated role in mother–infant interactions.  相似文献

The Self‐Directed Search (SDS; Holland, 1994 ) is sometimes administered to large student groups outside of counseling to address common career development needs. This study evaluated the effectiveness of the SDS as a stand‐alone intervention by comparing a general sample of college students who completed the SDS (n = 39) with a no‐treatment control group (n = 41) on several outcomes. Completion of the SDS related to an increase in the number of career alternatives being considered 4 weeks later but did not relate to career exploration, career decision‐making self‐efficacy, career indecision, and seeking of career counseling services. If the SDS is used outside of counseling with broad student samples, the authors suggest providing additional intervention to ensure that it promotes exploration of any additional careers being considered.  相似文献

The role of contingency learning was examined in 3‐month‐old infants' reaching movements. Infants in the experimental group experienced 9 min of active training during which they could move their arms in a reach‐like fashion to pull and move a mobile. Infants in the control group experienced 9 min of passive training during which they watched a mobile move. Prior to (pre‐training) and following the mobile experience (post‐training), infants in both conditions were given an opportunity to interact with a rattle placed within and out of their reach. Compared with infants in the control condition, infants in the experimental condition produced reach‐like movements more frequently during the mobile experience; they also showed a greater increase in reaching attempts from pre‐ to post‐training assessments with the rattle. These findings show that reinforcement of arm extensions and retractions increases the frequency of infants' reaching behaviors. This result suggests that the reinforcement of components of infants' behaviors may contribute to the successful assembly of these behaviors. This process could help keep infants engaged during the lengthy transition from prereaching to independent reaching.  相似文献

The authors explore the construct of profile elevation on interest inventories results. They speak to the need for career counselors to maximize their use of the interest inventory and how they can do that by properly interpreting profile elevation. Profile elevation is defined, and correlates of high and low profile elevation are presented. The common interpretive interaction that occurs between profile elevation and differentiation is explored. The authors also present a case of low profile elevation and the career counseling interventions and considerations used with the client.  相似文献

College students experience a number of stressors, such as adjustment to a new environment, postgraduation planning, and the balancing of changing roles and responsibilities. These stressors may contribute to increased rates of psychological distress that have implications for their educational and career development. The purpose of this study was to extend understanding of the nature of the relationships among psychological distress, self‐esteem, and career decision self‐efficacy (CDSE) beliefs. Results from 292 undergraduate students demonstrated support for the proposed hypotheses. Psychological distress negatively related to self‐esteem and to CDSE. Self‐esteem was positively related to, yet distinct from, CDSE, and both self‐esteem and psychological distress contributed unique variance to the prediction of CDSE. Results highlight the importance of attending to student psychological distress in the provision of career counseling services. Future research that centralizes mental health is needed to better understand relationships among career development processes over time and within diverse student populations.  相似文献

Many early adolescents experience peer victimization, but little research has examined how they respond to aggression by peers. Thus, in a large sample of early adolescents (= 648; M age = 12.96; SD = 0.30; 52.0% female), we examined (1) the associations between peer‐reported victimization and self‐reported responses to peer provocation, and (2) whether these associations were moderated by peer‐reported aggression. In particular, we predicted that the reported use of assertion, a strategy generally viewed as socially skillful, would be associated with less victimization, but only for youth low on peer‐reported aggression. Results were consistent with this hypothesis. Moreover, seeking adult intervention was associated with greater victimization for youth high on peer‐reported aggression. Implications for research and practice are discussed.  相似文献

In the United Kingdom (UK), the number of convictions for offences related to child abuse images fell back following the police investigation dubbed ‘Operation Ore’, but have still continued at levels unimaginable only 10 years ago. However, while government and the internet industry deserve credit for the steps they have taken to reduce the traffic in child abuse images online in the UK, the fact that a number of Internet Service Providers appear to be reluctant to act to block access to it calls into question the effectiveness of the self‐regulatory principle: the idea which has been central to the UK’s overall approach to internet policy since 1996.  相似文献

Mothers modify their actions when demonstrating objects to infants versus adults. Such modifications have been called infant‐directed action (IDA) or motionese (Brand, Baldwin, & Ashburn, 2002). We investigated the IDA features of interactiveness and simplification by quantifying eye gaze, object exchanges, and action units enacted between exchanges in 42 mothers' demonstrations of novel objects to infants (6–8 months or 11–13 months) or adults. We found more eye gaze, more object exchanges, and fewer action types per turn in demonstrations to infants relative to adults. Unlike prior research using global measurements, we detected differences in behavior directed at infants of different ages: Shorter, more frequent gazes and more exchanges characterized demonstrations to older versus younger infants. These findings indicate the fruitfulness of fine‐grained analysis of IDA, and further clarify how adults may support infants' processing of human motion.  相似文献

This study explored the role of maternal sensitivity and infant‐directed speech (IDS) prosody in infants’ expression and regulation of negative emotion. Seventy mothers and their 3‐month‐old infants were observed during the Still‐Face Paradigm (SFP). Maternal sensitivity and IDS prosody were assessed at baseline and infant negative affect in the baseline, still‐face, and reunion episodes. Results showed that prototypical IDS prosody characterized by wider fundamental frequency (F0) variability was related to decreases in infant's negative affect, but only if accompanied by maternal sensitivity. Infants of sensitive mothers who spoke with more prototypical IDS prosody showed better abilities to regulate negative affect during the SFP. When prototypical IDS prosody was accompanied by low maternal sensitivity, infants showed lower regulation of negative emotions. In conclusion, infant negative affect regulation in a dyadic setting is facilitated by an optimal combination of both more prototypical maternal IDS prosody and maternal sensitive responsiveness. Implications for the study of mother–infant interaction are discussed.  相似文献

This study sought to examine the electrophysiological correlates of visual perceptual priming in a sample of low risk preterm infants. We compared the ERP data of 20 healthy preterm infants at the age of 6 months (corrected age: 4 months) to those of 20 six‐month‐old and 20 four‐month‐old full term infants. The comparison groups represented the preterm infants' chronological and corrected ages respectively. The results showed that the brain responses of the preterm infants at the age of 6 months, specifically the topography and the latency of the Nc component, are more similar to those of their corrected age peers than to those of the chronological age controls.  相似文献

Face preferences for speakers of infant‐directed and adult‐directed speech (IDS and ADS) were investigated in 4‐ to 13.5‐month‐old infants of depressed and nondepressed mothers. Following 1 min of exposure to an ID or AD speaker (order counterbalanced), infants had an immediate paired‐comparison test with a still, silent image of the familiarized versus a novel face. In the test phase, ID face preference ratios were significantly lower in infants of depressed than nondepressed mothers. Infants' ID face preference ratios, but not AD face preference ratios, correlated with their percentile scores on the cognitive (Cog) scale of the Bayley Scales of Infant & Toddler Development (3rd Edition; BSID‐III), assessed concurrently. Regression analyses revealed that infant ID face preferences significantly predicted infant Cog percentiles even after demographic risk factors and maternal depression had been controlled. Infants may use IDS to select social partners who are likely to support and facilitate cognitive development.  相似文献

Intentional self‐regulation (ISR) is thought to undergo significant development during the second decade of life, but our understanding of ISR's development during this period remains incomplete. We discuss the development of ISR as operationalized by Freund & Baltes's (2002) measure of selection, optimization, and compensation (SOC). We use data from 5,471 youth that had participated in the 4‐H Study of Positive Youth Development in Grades 5 through 12. Using exploratory factor analyses, our findings suggest that the SOC questionnaire adheres to a stable three‐factor structure across adolescence, with factors representing selection, intentional self‐regulation, and a reverse‐coded method factor. We discuss the implications of our findings for future research.  相似文献

This paper reviews the burgeoning sociological literature on non‐suicidal self‐injury, in which individuals intentionally harm themselves by cutting, burning, scratching, or smashing their body parts. We identify challenges to studying self‐injury, such as conflicting definitions and categorizations. Comparing self‐injury to other behaviors such as suicide, body modification, and self‐mutilation, we assert that non‐suicidal self‐injury deserves its own conceptual category. We explain how a critical sociological approach provides a valuable counterweight to medical and psychological studies of self‐injury. In particular, this paper advances the deviance perspective. Finally, we highlight how technology has allowed self‐injurers to build supportive communities in cyberspace, blurring the line between hidden and public acts. We conclude with suggestions for future directions in the study of self‐injury.  相似文献
