Do infants use past linguistic information to interpret an ambiguous request for an object? When infants in this research were shown 2 objects, and asked for 1 with an indefinite request (e.g., "Can you get it for me?"), both 15- and 18-month-olds used the speaker's previous reference to an absent object to interpret the request. The 18-month-olds did so even when the request was made after a 2.5-min delay. When the request was made by a person who did not participate in the conversation, the infants did not use the previous verbal information. These results demonstrate infants' ability to use language as a source of information in ambiguous contexts and indicate an early appreciation of the shared nature of conversation. 相似文献

Two studies investigated how preschool children's interpretations of novel words as names for parts of objects were affected by 3 kinds of information: (a) whole object familiarity, (b) whole part juxtaposition, and (c) syntactic information indicating possession. Study 1 tested 3- to 4-year-olds and found that although there was evidence that all information affected children's part-term interpretations to some extent, they were most systematic when provided with 2 or more kinds of information. Study 2 adapted the procedure for use with 2.5-year-olds and found the same general pattern of results. Variations across studies were found that may reflect changes in how different kinds of information affect word learning with development. 相似文献

Infants parse dynamic action 总被引：6，自引：0，他引：6
As observers of human behavior, infants are faced with a complex flow of motion in which pauses are rare and only occasionally coincide with boundaries between intentional actions. Two studies investigated whether, despite such complexity, 10- to 11-month-old infants (N = 16 for each study) possess skills for parsing ongoing behavior along boundaries correlated with the initiation and completion of intentions. After being familiarized with digitized sequences of continuous everyday action, infants showed renewed interest in test versions in which motion paused in the midst of an actor's pursuit of intentions (interrupting test videos). In contrast, pauses that suspended motion at intention boundary points (completing test videos) sparked no such renewed interest on infants' part. Moreover, basic salience differences between the two types of test videos were not the source of infants' increased interest when intentions were interrupted (Study 2). These findings demonstrate that infants readily detect disruptions of the structure inherent in intentional action, and hence parse ongoing behavior with respect to such structure. Such parsing skill is likely a prerequisite to the development of genuine intentional understanding. 相似文献

In previous studies, very young children have learned words while "overhearing" a conversation, yet they have had trouble learning words from a person on video. In Study 1, 64 toddlers (mean age=29.8 months) viewed an object-labeling demonstration in 1 of 4 conditions. In 2, the speaker (present or on video) directly addressed the child, and in 2, the speaker addressed another adult who was present or was with her on video. Study 2 involved 2 follow-up conditions with 32 toddlers (mean age=30.4 months). Across the 2 studies, the results indicated that toddlers learned words best when participating in or observing a reciprocal social interaction with a speaker who was present or on video. 相似文献

This research was conducted to understand paraprofessional home visitors’ perceptions of their training in addressing poor mental health, substance abuse, and domestic violence, and their actions in working with families in addressing these issues. Five focus groups were conducted with a total of 28 paraprofessional home visitors. Three main themes emerged from qualitative analysis. Home visitors experienced tension between addressing families’ more pressing needs such as housing or utilities and addressing poor mental health, substance abuse, and domestic violence. Home visitors felt that they received extensive training in these risk areas, but that this training focused heavily on knowledge acquisition rather than skill development. Home visitors also desired more guidance in addressing families’ poor mental health, substance abuse, and domestic violence concerns—namely, more clarity on the extent to which they should address these issues during visits and more and varied supervision. Home visitors need more training on how to initiate conversations about mental health, substance abuse, and domestic violence, including how to transition conversations from other client needs. Home visiting programs must clarify home visitors’ roles in addressing clients’ poor mental health, substance abuse, and domestic violence and provide additional and varied supervision to home visitors. 相似文献

OBJECTIVE: The purpose of this study was to determine which factors were significantly associated with court outcomes for drug exposed infants in dependency court. METHOD: A longitudinal study of 118 drug exposed infant social services and juvenile court files of petitioned cases through all court hearings, using chi-squares and logistic regressions data analysis. RESULTS: There was an overrepresentation of minority mothers who were poor, unemployed, undereducated, and single, with prior referrals to the dependency system and criminal records. The chi-square analysis suggested that variables such as ethnicity, past referrals, and criminal record were significantly associated with court outcomes for all hearings, with minority cases less likely to receive family maintenance orders, and more likely to have their children placed out of home. The regression analysis however showed a different pattern. Ethnicity and prior referrals disappeared as significant risk factors altogether. Only at the initial dispositional hearing did a criminal record significantly influence court decisions. In subsequent hearings, mothers' compliance with court orders and attending court hearings became the significant factors associated with court outcomes. CONCLUSIONS: Mothers' behavior was more important for court outcomes than ethnicity, past referrals, and criminal record. It is therefore imperative that mothers are motivated to successfully comply with court orders by offering culturally appropriate services and facilitating attendance at court hearings. 相似文献

Out of Reach,Out of Mind? Infants’ Comprehension of References to Hidden Inaccessible Objects

下载免费PDF全文 This study investigated the nature of infants’ difficulty understanding references to hidden inaccessible objects. Twelve‐month‐old infants (N = 32) responded to the mention of objects by looking at, pointing at, or approaching them when the referents were visible or accessible, but not when they were hidden and inaccessible (Experiment I). Twelve‐month‐olds (N = 16) responded robustly when a container with the hidden referent was moved from a previously inaccessible position to an accessible position before the request, but failed to respond when the reverse occurred (Experiment II). This suggests that infants might be able to track the hidden object's dislocations and update its accessibility as it changes. Knowing the hidden object is currently inaccessible inhibits their responding. Older, 16‐month‐old (N = 17) infants’ performance was not affected by object accessibility. 相似文献
