English‐monolingual children develop a shape bias early in language acquisition, such that they more often generalize a novel label based on shape than other features. Spanish‐monolingual children, however, do not show this bias to the same extent (Hahn & Cantrell, 2012). Studying children who are simultaneously learning both Spanish and English presents a unique opportunity to further investigate how this word‐learning bias develops. Thus, we asked how Spanish–English bilingual children (Mage = 21.31 months) perform in a novel‐noun generalization (NNG) task, specifically examining how past language experience (i.e. language exposure and vocabulary size) and present language context (i.e. whether the NNG task was conducted in Spanish or English) influence the strength of the shape bias. Participants completed the NNG task either entirely in English (N = 16) or entirely in Spanish (N = 16), as well as language understanding tasks in both English and Spanish to ensure that they understood what the experimenter was asking them to do. Parents completed a language exposure survey and vocabulary checklists in Spanish and English. There was a significant interaction between condition and choice type: Bilingual children in the English condition showed a shape bias in the NNG task, but bilingual children in the Spanish condition showed no reliable biases. No measures of past language experience were related to NNG task performance. These results suggest that when learning new words, bilingual children are attuned to the regularities of the present language context, and prior language experiences may play a more secondary role.  相似文献

There is a ‘theory of mind’ theory of autism. Meltzoff has recently developed a procedure that gives a nonverbal assessment of ‘theory of mind’. A group of children with autism and a matched control group of normally developing infants were given three of Meltzoff’s tasks and three conventional, gestural imitation tasks. The children with autism showed the expected deficits on gestural imitation, but were significantly better than the normally developing infants on the Meltzoff tasks. The implications of these results for a number of theoretical issues are discussed.  相似文献

Adults (151 female, 130 male; 17.4% African American/Black, 48% Caucasian, 22.8% Latino/Hispanic, 11.7% “other”) assigned postdivorce parental care and custody for four combinations of traditional/nontraditional mothers and fathers described in vignettes of divorcing parents. Parental gender characteristics influenced the assignment of parental care and child custody to divorcing mothers and fathers described in the scenarios and interacted with child gender. Across scenarios, female participants assigned more parental care and custody to mothers than did male participants. When feminine qualities were paired with masculine qualities, greater custody was assigned to the parent described with feminine characteristics (whether a father or mother) than when that parent was described with masculine characteristics. The role of feminine gender characteristics for child custody and care was discussed with regard to maternal primacy and possible changes for father involvement in the aftermath of divorce.  相似文献

Several long-term correlates of childhood sexual abuse (CSA) have been identified, including depression, fear, anxiety, guilt, anger, and poor interpersonal functioning (e.g., Browne and Finkelhor, 1986). However, little is know about how CSA survivors fare in old age. This article addresses the impact of unresolved CSA on late-life (emotional, cognitive, and behavioral) functioning. Three case studies of older adults ages 60 and older who were struggling with unresolved CSA are presented. Two observed stressors (loss of social support and declining health) and one developmental task (reminiscence or life-review) appear to be linked to exacerbated vulnerabilities in older survivors. Specifically, because CSA may arrest specific childhood developmental tasks (e.g., ability to form secure attachments, autonomy) or facilitate development of coping strategies that are maladaptive when outside of an abusive environment (e.g., generalized interpersonal distrust, avoidance, dissociation), the survivor may be at risk for developmental vulnerabilities for dysfunction in adulthood. These vulnerabilities may exacerbate unresolved CSA, particularly when the adult encounters stressors or developmental tasks that exceed his or her capacity for adaptive coping. Recommendations for mental health professionals and future research are suggested.  相似文献

Inoculation messages employed in past studies have been consistently preventative. Yet, if inoculation strategies are to be used in mass media campaigns, researchers need to know what the effects will be on all audience members—not just those known to support a message sponsor’s position. A 3‐phase experiment was conducted involving 558 participants. Linear regression analyses identified that initially supportive, neutral, and opposed subjects exposed to the inoculation message reported significantly more positive attitudes toward the study topic of agricultural biotechnology following an attack message than did their respective controls. The inoculation message contributed to significantly increased threat levels among initially neutral and opposed subjects and marginally increased counterarguing output among initially supportive and neutral subjects. Additionally, counterarguing partially mediated final attitudes for inoculated supportive subjects.  相似文献

This study examined the relationships between feedback seeking, goal orientation, performance and four motives which, though generally considered to underlie the feedback seeking process, have not previously been measured comprehensively. Both the likelihood and the number of instances of feedback seeking were measured in two samples (employees and students) in association with perceived or selfassessed above- and below-average performance. Self-assessed performance was a major predictor of feedback seeking; also influential were goal orientation and the goal orientation-performance interaction. Increased feedback seeking was associated with the desire for useful information motive, and reduced feedback seeking with the ego defence and defensive impression management motives. The desire for useful information motive mediated the influence of performance-prove goal orientation for employees, and that of a learning goal orientation for students.  相似文献

Competing stimulus assessments (CSAs) are designed to identify stimuli that, when made freely available, reduce problem behavior. Although CSAs have demonstrated utility, identifying competing stimuli can be difficult for some individuals. The current study describes outcomes from an augmented CSA (A-CSA) for 6 consecutively encountered cases with treatment-resistant subtypes of automatically maintained problem behavior. When test stimuli were made freely available, only between 0 and 1 effective competing stimuli were identified for each case. Prompting and response blocking were temporarily employed in succession to promote engagement with stimuli and disrupt problem behavior. When those procedures were withdrawn and stimuli made freely available, the number of effective competing stimuli increased in all 6 cases. Findings suggest that procedures designed to promote engagement and disrupt problem behavior may allow the A-CSA to be a platform not only for identifying competing stimuli, but also for actively establishing competing stimuli.  相似文献
