Why does visual working memory performance increase with age in childhood? One recent study ( Cowan et al., 2010b ) ruled out the possibility that the basic cause is a tendency in young children to clutter working memory with less‐relevant items (within a concurrent array, colored items presented in one of two shapes). The age differences in memory performance, however, theoretically could result from inadequate encoding of the briefly presented array items by younger children. We replicated the key part of the procedure in children 6–8 and 11–13 years old and college students (total N = 90), but with a much slower, sequential presentation of the items to ensure adequate encoding. We also required verbal responses during encoding to encourage or discourage labeling of item information. Although verbal labeling affected performance, age differences persisted across labeling conditions, further supporting the existence of a basic growth in capacity. 相似文献

This study examined the relative efficacy of explicit instruction and indirect priming on young children's behavior in a task that required a series of choices between a small immediate reward and a larger delayed reward. One hundread and six 4-year-old children were randomly assigned to one of four conditions involving one of two goals (maximize rewards or obtain immediate rewards) and one of two types of instruction (indirect priming using stories or explicit verbal instructions). Children were more likely to make goal-congruent choices as a result of indirect priming, but there was no effect of explicit instruction, suggesting that indirect approaches to changing young children's behavior may be more effective than direct approaches under some circumstances. These results have implications for understanding the dynamic interplay between bottom-up and top-down influences on self-regulation early in development. 相似文献

This study conducts an exploratory factor analysis on Wickman’s (2004) Pastors at Risk Inventory that measures the likelihood of whether clergy may face forced or unforced resignation. An online
survey was administered to 285 evangelical pastors containing 42 Likert-type items developed from 20 years of qualitative
practitioner ministry among clergy. The two factors identified—vision conflict and compassion fatigue—are discussed in relation
to the extant literature and in their unique function with clergy. Results indicate that varying levels of disparity typically
exist between expected ministry outcomes and actual ministry experiences, and that vision conflict and compassion fatigue
are more likely among clergy who lack a support team and/or whose church has recently plateaued or declined in attendance. 相似文献

Category training can induce category effects, whereby color discrimination of stimuli spanning a newly learned category boundary is enhanced relative to equivalently spaced stimuli from within the newly learned category (e.g., categorical perception). However, the underlying mechanisms of these acquired category effects are not fully understood. In the current study, Event-Related Potentials (ERPs) were recorded during a visual oddball task where standard and deviant colored stimuli from the same or different novel categories were presented. ERPs were recorded for a test group who were trained on these novel categories, and for an untrained control group. Category effects were only found for the test group on the trained region of color space, and only occurred during post-perceptual stages of processing. These findings provide new evidence for the involvement of cognitive mechanisms in acquired category effects and suggest that category effects of this kind can exist independent of early perceptual processes. 相似文献

We examine the contributions of dynamic systems theory to the field of cognitive development, focusing on modeling using dynamic neural fields. After introducing central concepts of dynamic field theory (DFT), we probe empirical predictions and findings around two examples—the DFT of infant perseverative reaching that explains Piaget's A-not-B error and the DFT of spatial memory that explain changes in spatial cognition in early development. Review of the literature around these examples reveals that computational modeling is having an impact on empirical research in cognitive development; however, this impact does not extend to neural and clinical research. Moreover, there is a tendency for researchers to interpret models narrowly, anchoring them to specific tasks. We conclude on an optimistic note, encouraging both theoreticians and experimentalists to work toward a more theory-driven future. 相似文献

Uncertainty is central to the experience of genetic decision making and counseling about cancer risk. Women seeking genetic
counseling about their breast cancer risk may experience a great deal of uncertainty about issues related to their daughters.
We used a theory of Communication and Uncertainty Management to guide analysis of sources of uncertainty about daughters that
emerged during 16 video-recorded and transcribed conversations between mothers at risk for a BRCA 1/2 mutation and their genetic healthcare practitioners. An interpretive design and constant comparative method revealed three
dominant patterns or themes representing sources of uncertainty mothers have relating to their daughters: disease risk, future
cancer screening, and communication of related information to daughters. Both practitioners and mothers discussed these aspects
of uncertainty. The findings identify the significant role uncertainty and familial concerns play in mothers’ genetic testing
decision making process. To assist genetic practitioners, we highlight daughter-related concerns that mothers are uncertain
about and which are vital to their genetic counseling needs. 相似文献

The purpose of this study was to specify the relationship between positive and harsh parenting and maternal scaffolding behavior. A 2nd aim was to disentangle the effects of maternal education and parenting quality, and a 3rd aim was to test whether parenting quality mediated the association between maternal education and scaffolding practices. We examined associations between positive and harsh parenting practices and contingent and noncontingent tutoring strategies. Ninety-six mother-child dyads (49 boys, 47 girls) from working- and middle-class English families participated. Mothers reported on parenting quality at Time 1 when children were 5 years old and again approximately 5 years later at Time 2. Mother-child pairs were observed working together on a block design task at Time 2, and interactions were coded for contingent (contingent shifting) and noncontingent (fixed failure feedback) dimensions of maternal scaffolding behavior. Positive and harsh parenting accounted for variance in contingent behavior over and above maternal education, whereas only harsh parenting accounted for unique variance in noncontingent scaffolding practices. Our findings provide new evidence for a more differentiated model of the relation between general parenting quality and specific scaffolding behaviors. 相似文献
