The organization of category-selective regions in ventral visual cortex is well characterized in human adults. We investigated a crucial, previously unaddressed, question about how this organization emerges developmentally. We contrasted the developmental trajectories for face-, object-, and place-selective activation in the ventral visual cortex in children, adolescents, and adults. Although children demonstrated adult-like organization in object- and place-related cortex, as a group they failed to show consistent face-selective activation in classical face regions. The lack of a consistent neural signature for faces was attributable to (1) reduced face-selectivity and extent of activation within the regions that will become the FFA, OFA, and STS in adults, and (2) smaller volumes and considerable variability in the locus of face-selective activation in individual children. In contrast, adolescents showed an adult-like pattern of face-selective activation, although it was more right-lateralized. These findings reveal critical age-related differences in the emergence of category-specific functional organization in the visual cortex and support a model of brain development in which specialization emerges from interactions between experience-dependent learning and the maturing brain. 相似文献

ABSTRACT— Previous research suggests that a language learned during early childhood is completely forgotten when contact to that language is severed. In contrast with these findings, we report leftover traces of early language exposure in individuals in their adult years, despite a complete absence of explicit memory for the language. Specifically, native English individuals under age 40 selectively relearned subtle Hindi or Zulu sound contrasts that they once knew. However, individuals over 40 failed to show any relearning, and young control participants with no previous exposure to Hindi or Zulu showed no learning. This research highlights the lasting impact of early language experience in shaping speech perception, and the value of exposing children to foreign languages even if such exposure does not continue into adulthood. 相似文献

One of the most intriguing findings on language comprehension is that violations of syntactic predictions can affect event-related potentials as early as 120 ms, in the same time-window as early sensory processing. This effect, the so-called early left-anterior negativity (ELAN), has been argued to reflect word category access and initial syntactic structure building (Friederici, 2002). In two experiments, we used magnetoencephalography to investigate whether (a) rapid word category identification relies on overt category-marking closed-class morphemes and (b) whether violations of word category predictions affect modality-specific sensory responses. Participants read sentences containing violations of word category predictions. Unexpected items varied in whether or not their word category was marked by an overt function morpheme. In Experiment 1, the amplitude of the visual evoked M100 component was increased for unexpected items, but only when word category was overtly marked by a function morpheme. Dipole modeling localized the generator of this effect to the occipital cortex. Experiment 2 replicated the main results of Experiment 1 and eliminated two non-morphology-related explanations of the M100 contrast we observed between targets containing overt category-marking and targets that lacked such morphology. Our results show that during reading, syntactically relevant cues in the input can affect activity in occipital regions at around 125 ms, a finding that may shed new light on the remarkable rapidity of language processing. 相似文献

This study examined patterns of growth across benchmark assessments for curriculum-based measures (CBM) over 2 academic years, with the twofold purpose of replicating earlier findings of growth patterns on R-CBM and conducting a preliminary investigation of growth patterns on M-CBM and CBM-Maze. The sample included 898 cases from 3rd through 5th grade over 2 academic years from one elementary school in the rural Midwest. All students participated in tri-annual benchmark assessments in which they were administered R-CBM, CBM-Maze, and M-CBM. Repeated measures analysis of variance was used to examine patterns of growth for all three measures. Students demonstrated greater R-CBM weekly growth during winter-to-spring than fall-to-winter across grade levels. Patterns for CBM-Maze and M-CBM were somewhat inconsistent across school years and grade levels. Results are discussed in terms of contextual variables that may impact within-year growth patterns and technical characteristics of CBM slopes. 相似文献

We examined the relation between cognitive development and fear, anxiety, and behavioral inhibition in a non-clinical sample
of 226 Dutch children aged 4–9 years. To assess cognitive development, children were tested with Piagetian conservation tasks
and a Theory-of-Mind (TOM) test. Fears were measured by means of a self-report scale completed by the children, while anxiety
symptoms and behavioral inhibition were indexed by rating scales that were filled out by parents. Significant age trends were
observed for some anxiety phenomena. For example, younger children displayed higher fear scores, whereas older children exhibited
higher levels of generalized anxiety. Most importantly, results of regression analyses (in which we controlled for age) indicated
that cognitive development, and in particular TOM ability, made a unique and significant contribution to various domains of
behavioral inhibition. In all cases, higher levels of TOM were associated with lower levels of behavioral inhibition. In general,
percentages of explained variance were rather small (i.e., <6%), indicating that the role of cognitive development in various
anxiety phenomena is limited. 相似文献

ObjectivesThe present study explored the experience of introjected regulation (i.e. a controlling motivational regulation in which people act due to internal pressures that are regulated by contingent self-esteem; [Ryan, R. M., & Deci, E. L. (2000). Intrinsic and extrinsic motivations: classic definitions and new directions. Contemporary Educational Psychology, 25, 54–56]) in relation to sport and exercise in mid-adolescence.MethodsAdolescents reporting strong introjected regulation of sport and/or exercise relative to their peers were identified using quantitative questionnaires, and invited for interview. Semi-structured interviews were recorded with 10 boys and 8 girls (mean age 14 years), transcribed verbatim, and analysed using an interpretive phenomenological approach.ResultsIntrojected regulation accompanied high levels of self-determined motivation, and was associated with high levels of physical activity in the present sample. Two major themes emerged: (i) gender differences in the basis for introjected regulation; and (ii) differences in the reasons and goals underpinning self-determined versus introjected regulations for exercise. In boys, introjected regulation was largely related to social factors, such as avoiding social disapproval and attaining ego enhancement. Girls rarely exercised with their friends, and introjected regulation more commonly reflected the partial internalization of a health and fitness rationale. In many cases, self-determined and introjected regulations were underpinned by different goals or reasons, supporting the importance of assessing an individual's multiple motives towards activities.ConclusionsIntrojected regulation for exercise was associated with higher than expected levels of participation in sport and exercise, regardless of whether it was founded on contingent self-worth, or the partial internalization of adaptive reasons for exercise. The implications of social control on future exercise participation are discussed. 相似文献

A study of 80 couples (mean age 24) examined the impact of attachment patterns on reactions to manipulated positive or negative feedback, ostensibly from partners. As expected, individuals high in attachment anxiety reported more negative mood and the least indifference to partner feedback. In addition, those high in attachment anxiety reported more negative reactions to negative feedback compared to those low in anxiety. Those high in attachment anxiety reported lower self‐competence after receiving negative feedback than those low in anxiety. Further, reactions to manipulated feedback mediated the relationship between attachment anxiety and self‐competence. Attachment models play a role in determining reactions to partner feedback and moderate how feedback is used to maintain self‐views. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Two studies evaluated whether there was a subtype of menopausal women and, if so, how it differed from the global gender stereotype. Study 1 had participants generate items associated with women going through menopause, midlife women, and midlife men. Results showed that there is a menopausal women stereotype, and it is mostly negative in content. Moreover, this stereotype differs from the perceptions of women in general. Study 2 examined the effects of the menopausal women stereotype by employing the illusory correlation paradigm (e.g., McConnell, Sherman, & Hamilton, 1994) and found that participants greatly overestimated the number of times that menopausal women and negative moods appeared together. This research highlights the importance of examining stereotype subtypes and subgroups 相似文献

Context processing in older adults: evidence for a theory relating cognitive control to neurobiology in healthy aging. 总被引:6,自引:0,他引:6
T S Braver D M Barch B A Keys C S Carter J D Cohen J A Kaye J S Janowsky S F Taylor J A Yesavage M S Mumenthaler W J Jagust B R Reed 《Journal of experimental psychology. General》2001,130(4):746-763
A theory of cognitive aging is presented in which healthy older adults are hypothesized to suffer from disturbances in the processing of context that impair cognitive control function across multiple domains, including attention, inhibition, and working memory. These cognitive disturbances are postulated to be directly related to age-related decline in the function of the dopamine (DA) system in the prefrontal cortex (PFC). A connectionist computational model is described that implements specific mechanisms for the role of DA and PFC in context processing. The behavioral predictions of the model were tested in a large sample of older (N = 81) and young (N = 175) adults performing variants of a simple cognitive control task that placed differential demands on context processing. Older adults exhibited both performance decrements and, counterintuitively, performance improvements that are in close agreement with model predictions. 相似文献
