Embodied attention and word learning by toddlers 总被引:1,自引:0,他引:1
Many theories of early word learning begin with the uncertainty inherent to learning a word from its co-occurrence with a visual scene. However, the relevant visual scene for infant word learning is neither from the adult theorist's view nor the mature partner's view, but is rather from the learner's personal view. Here we show that when 18-month old infants interacted with objects in play with their parents, they created moments in which a single object was visually dominant. If parents named the object during these moments of bottom-up selectivity, later forced-choice tests showed that infants learned the name, but did not when naming occurred during a less visually selective moment. The momentary visual input for parents and toddlers was captured via head cameras placed low on each participant's forehead as parents played with and named objects for their infant. Frame-by-frame analyses of the head camera images at and around naming moments were conducted to determine the visual properties at input that were associated with learning. The analyses indicated that learning occurred when bottom-up visual information was clean and uncluttered. The sensory-motor behaviors of infants and parents were also analyzed to determine how their actions on the objects may have created these optimal visual moments for learning. The results are discussed with respect to early word learning, embodied attention, and the social role of parents in early word learning. 相似文献

In this study, we investigated the effects of functional group counseling on inspiring low achievers' self-worth and self-efficacy in Taiwan. Forty-three 10th grade low-achieving students volunteered as the Experimental Group to join a 24-week intervention, which integrated and utilized functional group counseling; another 51 10th grade low-achieving students volunteered to be Comparison Group I. In addition, 43 10th grade moderate or high academic achieving students volunteered to be Comparison Group II. All participants completed the Vocational School Student Questionnaire at the beginning and end of this study to measure their self-worth and self-efficacy. In addition, six target students (two boys and four girls) with the lowest total scores on self-worth or self-efficacy in the pretest were selected from the Experimental Group to be interviewed at the end of the intervention and observed weekly. Analyses of variance, analyses of covariance, and paired t-tests assessed the similarity and differences among groups. The initial findings were as follows: Experimental group students had significantly higher scores on self-efficacy and self-worth than both Comparison Group I and Group II students and functional group counseling was shown to significantly affect the low-achieving students. Qualitative results from interviews and observations were used for triangulation and consolidation of quantitative results. Implications of the study included the recommended use of functional group counseling with low-achieving students. 相似文献

We examined a procedure consisting of a preference assessment, prompting, contrived conditioned establishing operations, and consequences for correct and incorrect responses for teaching children with autism to mand “which?” We used a modified multiple baseline design across 3 participants. All the children learned to mand “which?” Generalization occurred to the natural environment, to a novel activity, and to a novel container; the results were maintained over time.Key words: mand for information, verbal behavior, verbal operant, whichContrived motivating operations have been used to teach mands for information to children with autism, including the mands “what?” (e.g., Williams, Donley, & Keller, 2000), “where?” (e.g., Betz, Higbee, & Pollard, 2010; Lechago, Carr, Grow, Love, & Almason, 2010), and “who?” (e.g., Endicott & Higbee, 2007; Sundberg, Loeb, Hale, & Eigenheer, 2002). More recently, researchers have examined the effects of contriving establishing operations (CEOs) in four different ways to teach children with autism to acquire the mands “what?” (Marion, Martin, Yu, & Buhler, 2011; Roy-Wsiaki, Marion, Martin, & Yu, 2010) and “where?” (Marion, Martin, Yu, Buhler, & Kerr, in press). Like the mands “what?” and “where?,” the mand “which?” is a mand for information that gives the speaker the ability to gather specific information regarding an item (e.g., “Which book is mine?”). Given the dearth of research that has examined interventions to teach mands for information using “which?,” the purpose of the present study was to extend the work of Marion et al. (2011, in press) by contriving one of four CEOs for teaching the mand “which?” to children with autism, and to assess for generalization to the other CEOs, the natural environment, and over time. 相似文献

This study examined whether attachment to God moderated the relation between perceived stress and well‐being (i.e., life satisfaction and positive affect) among 183 Chinese Christian international students and immigrants. Results showed significant main effects of (a) perceived stress on life satisfaction and (b) secure attachment to God and avoidant attachment to God on life satisfaction and positive affect. There was a significant interaction of perceived stress and avoidant attachment to God on life satisfaction. Specifically, high avoidant attachment to God exacerbated the association between perceived stress and life satisfaction, whereas low avoidant attachment to God buffered the association between perceived stress and life satisfaction. 相似文献

Two hypotheses were tested in this study. First, blockade of neural activity by lidocaine immediately following the retrieval of a memory may impair the reconsolidation and subsequent expression of that memory. Second, a non-retrieved memory would not be affected by this lidocaine treatment. Since the basolateral nucleus of the amygdala (BLA) is involved in emotion-related memory, an intra-BLA lidocaine infusion was used immediately after the retrieval of two emotion-related memories, the step-through passive avoidance response (PA) and cocaine-induced conditioned place preference (CPP). Intra-BLA lidocaine infusion immediately after cocaine-induced CPP retrieval diminished CPP magnitude in retests. However, intra-BLA lidocaine infusion alone did not affect cocaine-induced CPP performance. Intra-BLA lidocaine infusion immediately after PA retrieval decreased PA performance in retests. Omission of PA retrieval procedure, intra-BLA lidocaine infusion did not affect subsequent PA performance. Surprisingly, intra-BLA lidocaine infusion immediately following the retrieval of PA or cocaine-induced CPP diminished both PA and cocaine-induced CPP performance in the retests. Finally, Fos-staining results revealed that a number of BLA neurons were activated by the retrieval of both cocaine-induced CPP and PA. We conclude that inactivation of neural activity in BLA immediately following retrieval of a fear or cocaine-conditioned memory can impair subsequent expression of both memories. More importantly, retrieval of a memory does not seem to be an absolute condition for rapidly changing the memory. 相似文献
