Adult neuroimaging studies have demonstrated dissociable neural activation patterns in the visual cortex in response to letters (Latin alphabet) and numbers (Arabic numerals), which suggest a strong experiential influence of reading and mathematics on the human visual system. Here, developmental trajectories in the event‐related potential (ERP) patterns evoked by visual processing of letters, numbers, and false fonts were examined in four different age groups (7‐, 10‐, 15‐year‐olds, and young adults). The 15‐year‐olds and adults showed greater neural sensitivity to letters over numbers in the left visual cortex and the reverse pattern in the right visual cortex, extending previous findings in adults to teenagers. In marked contrast, 7‐ and 10‐year‐olds did not show this dissociable neural pattern. Furthermore, the contrast of familiar stimuli (letters or numbers) versus unfamiliar ones (false fonts) showed stark ERP differences between the younger (7‐ and 10‐year‐olds) and the older (15‐year‐olds and adults) participants. These results suggest that both coarse (familiar versus unfamiliar) and fine (letters versus numbers) tuning for letters and numbers continue throughout childhood and early adolescence, demonstrating a profound impact of uniquely human cultural inventions on visual cognition and its development. 相似文献

This research examines the relationship of social capital with the acculturation attitudes and sociocultural adaptation of 122 migrants from Central Asian republics of the former Union of Soviet Socialist Republics (Uzbekistan, Tajikistan, Turkmenistan, Kyrgyzstan, and Kazakhstan) and 136 migrants from South Korea. The questionnaire included scales for assessing acculturation attitudes (integration, assimilation, and separation), individual social capital (bridging and bonding), and sociocultural adaptation. Using parallel mediation analysis, we found that acculturation attitudes for migrants from Central Asia are secondary to their social capital in relation to sociocultural adaptation. However, among migrants from South Korea, social capital is not linked to their acculturation attitudes, and in general, its role in sociocultural adaptation is lower as compared to the role of acculturation attitudes. As a whole, our research shows that although sociocultural adaptation for all ethnic groups is linked to acculturation attitudes and social capital, acculturation attitudes for certain ethnic groups can be dependent on social capital. 相似文献

A resampling algorithm is presented for analyzing multiway contingency tables with fixed marginal frequency totals. Applications are illustrated with extensions of Fisher's exact, Pearson's chi-squared, and likelihood-ratio tests to three-way contingency tables. 相似文献

In this paper, I will distinguish two varieties of external world skepticism: belief and confidence skepticism. I will argue that we can defang the intuitive motivations for confidence skepticism (though not a meeker “argument from might,” which got some attention in the twentieth century literature on external world skepticism) by adopting a partially psychologistic answer to the problem of priors. And I will argue that certain recent work in the epistemology of mathematics and logic provides independent support for such psychologism. 相似文献

The processing of abbreviations in reading was examined with an eye movement experiment. Abbreviations were of 2 distinct types: acronyms (abbreviations that can be read with the normal grapheme-phoneme correspondence [GPC] rules, such as NASA) and initialisms (abbreviations in which the GPCs are letter names, such as NCAA). Parafoveal and foveal processing of these abbreviations was assessed with the use of the boundary change paradigm (K. Rayner, 1975). Using this paradigm, previews of the abbreviations were either identical to the abbreviation (NASA or NCAA), orthographically legal (NUSO or NOBA), or illegal (NRSB or NRBA). The abbreviations were presented as capital letter strings within normal, predominantly lowercase sentences and also sentences in all capital letters such that the abbreviations would not be visually distinct. The results indicate that acronyms and initialisms undergo different processing during reading and that readers can modulate their processing based on low-level visual cues (distinct capitalization) in parafoveal vision. In particular, readers may be biased to process capitalized letter strings as initialisms in parafoveal vision when the rest of the sentence is normal, lowercase letters. 相似文献

Social rejection can create powerful changes in people's brains and bodies. In the study reported here, we examined brain-based individual differences associated with buffering against cardiovascular threat responses to social rejection. Using EEG source-localization techniques, we examined differences in intracortical asymmetry. We predicted that individuals with greater left relative to right dorsolateral prefrontal activity would show a more approach-motivated response to social rejection. Eighty-four female participants were randomly assigned to one of three stressful situations: social rejection, social evaluation without rejection, or self-evaluation. Among participants assigned to the social-rejection condition, greater left relative to right prefrontal intracortical activity at baseline was associated with more adaptive cardiovascular profiles and more self-reported approach-oriented emotions. Participants in the other conditions did not show these relationships. Our data are the first to show that social context matters when attempting to link individual differences in cortical asymmetry with approach-related cardiovascular and emotional outcomes. 相似文献

Much of the recent research on counterproductive work behaviors (CWBs) has used multi-item self-report measures of CWB. Because of concerns over self-report measurement, there have been recent calls to collect ratings of employees' CWB from their supervisors or coworkers (i.e., other-raters) as alternatives or supplements to self-ratings. However, little is still known about the degree to which other-ratings of CWB capture unique and valid incremental variance beyond self-report CWB. The present meta-analysis investigates a number of key issues regarding the incremental contribution of other-reports of CWB. First, self- and other-ratings of CWB were moderately to strongly correlated with each other. Second, with some notable exceptions, self- and other-report CWB exhibited very similar patterns and magnitudes of relationships with a set of common correlates. Third, self-raters reported engaging in more CWB than other-raters reported them engaging in, suggesting other-ratings capture a narrower subset of CWBs. Fourth, other-report CWB generally accounted for little incremental variance in the common correlates beyond self-report CWB. Although many have viewed self-reports of CWB with skepticism, the results of this meta-analysis support their use in most CWB research as a viable alternative to other-reports. 相似文献

[Formula: see text] This article reviews recent work aimed at developing a new framework, based on signal detection theory, for understanding the relationship between explicit (e.g., recognition) and implicit (e.g., priming) memory. Within this framework, different assumptions about sources of memorial evidence can be framed. Application to experimental results provides robust evidence for a single-system model in preference to multiple-systems models. This evidence comes from several sources including studies of the effects of amnesia and ageing on explicit and implicit memory. The framework allows a range of concepts in current memory research, such as familiarity, recollection, fluency, and source memory, to be linked to implicit memory. More generally, this work emphasizes the value of modern computational modelling techniques in the study of learning and memory. 相似文献
