The process by which adults develop competence in symbolic mathematics tasks is poorly understood. Nonhuman animals, human
infants, and human adults all form nonverbal representations of the approximate numerosity of arrays of dots and are capable
of using these representations to perform basic mathematical operations. Several researchers have speculated that individual
differences in the acuity of such nonverbal number representations provide the basis for individual differences in symbolic
mathematical competence. Specifically, prior research has found that 14-year-old children’s ability to rapidly compare the
numerosities of two sets of colored dots is correlated with their mathematics achievements at ages 5–11. In the present study,
we demonstrated that although when measured concurrently the same relationship holds in children, it does not hold in adults.
We conclude that the association between nonverbal number acuity and mathematics achievement changes with age and that nonverbal
number representations do not hold the key to explaining the wide variety of mathematical performance levels in adults. 相似文献

This study aimed to provide evidence for a Global Precedence Effect (GPE) in both vision and audition modalities. In order to parallel Navon's paradigm, a novel auditory task was designed in which hierarchical auditory stimuli were used to involve local and global processing. Participants were asked to process auditory and visual hierarchical patterns at the local or global level. In both modalities, a global-over-local advantage and a global interference on local processing were found. The other compelling result is a significant correlation between these effects across modalities. Evidence that the same participants exhibit similar processing style across modalities strongly supports the idea of a cognitive style to process information and common processing principle in perception. 相似文献

In a birth cohort of 6281 men from Aberdeen, Scotland, social class of origin, childhood intelligence, childhood behavior disturbance and education were examined as predictors of status attainment in midlife (46 to 51 years). Social class of origin, intelligence and behavior disturbance were conceptualized as correlated predictors, whose effects were hypothesized to be partially mediated by educational qualifications. A structural equation model using Full Information Maximum Likelihood estimation confirmed that education had the strongest direct effect on status attainment at midlife. Furthermore, education partially mediated the effects of social class of origin and childhood intelligence, and fully mediated the effects of behavior disturbance on status attainment. Social class of origin, childhood intelligence and behavior disturbance were strongly inter-correlated. After controlling for these associations, educational and social status attainments were influenced to a considerably greater extent by childhood intelligence than by social class of origin. 相似文献

The time-based resource-sharing model of working memory assumes that memory traces suffer from a time-related decay when attention is occupied by concurrent activities. Using complex continuous span tasks in which temporal parameters are carefully controlled, P. Barrouillet, S. Bernardin, S. Portrat, E. Vergauwe, & V. Camos (2007) recently provided evidence that any increase in time of the processing component of these tasks results in lower recall performance. However, K. Oberauer and R. Kliegl (2006) pointed out that, in this paradigm, increased processing times are accompanied by a corollary decrease of the remaining time during which attention is available to refresh memory traces. As a consequence, the main determinant of recall performance in complex span tasks would not be the duration of attentional capture inducing time-related decay, as Barrouillet et al. (2007) claimed, but the time available to repair memory traces, and thus would be compatible with an interference account of forgetting. The authors demonstrate here that even when the time available to refresh memory traces is kept constant, increasing the processing time still results in poorer recall, confirming that time-related decay is the source of forgetting within working memory. 相似文献

The present study investigated whether the conditions that make interracial contact anxiety-provoking for Whites differ from those that make it anxiety-provoking for Blacks. Specifically, the present work examined interracial anxiety as a function of discussant race (i.e., White or Black) and discussion topic (i.e., race-related or race-neutral). To that end, we examined the nonverbal behavior of White and Black participants during brief interpersonal interactions. Consistent with previous research, White participants behaved more anxiously during interracial than same-race interactions. Additionally, White participants of interracial interaction behaved more anxiously than their Black interaction partners. Furthermore, whereas White participants of interracial interactions found race-related discussions no more stressful than race-neutral discussions, Black participants of interracial interactions found race-related discussions less stressful than race-neutral discussions. The implications of these racial and contextual differences in interracial anxiety for improving interracial contact and race relations, more broadly, are discussed. 相似文献

The present research investigated the extent to which the stereotype that young Black men are threatening and dangerous has become so robust and ingrained in the collective American unconscious that Black men now capture attention, much like evolved threats such as spiders and snakes. Specifically, using a dot-probe detection paradigm, White participants revealed biased attention toward Black faces relative to White faces (Study 1). Because the faces were presented only briefly (30-ms), the bias is thought to reflect the early engagement of attention. The attentional bias was eliminated, however, when the faces displayed averted eye-gaze (Study 2). That is, when the threat communicated by the Black faces was attenuated by a relevant, competing socio-emotional cue—in this case, averted eye-gaze—they no longer captured perceivers’ attention. Broader implications for social cognition, as well as public policies that reify these prevailing perceptions of young Black men are discussed. 相似文献

The phonological priming paradigm provides an interesting methodological tool for studying various components of the speech recognition process. However, concerns about response biases distorting the effects have been repeatedly voiced. This article reviews the main studies on priming and aims to distinguish effects under automatic processes from those under some level of strategic control. Both controlled and automatic processes appear to be responsible for the effects observed in phonological priming experiments. Nonetheless, with careful procedures, it is possible to separate them. 相似文献

This study examines the structure of self‐estimates of intelligence (SEI) across 12 nations (Australia, Austria, Brazil, France, Iran, Israel, Malaysia, South Africa, Spain, Turkey, UK and US). Participants rated themselves on general and specific abilities from three popular models of intelligence: Gardner's multiple intelligences, Sternberg's triarchic theory of intelligence, and Goleman's emotional intelligence. The results showed that (a) laypeople across nations have similar and invariant concepts of intelligence, (b) concepts of intelligence are cross‐culturally closely related to academic notions of intellectual ability and (c) sex differences in general and specific SEI favouring men are consistent across countries. Male hubris and female humility in SEI seem independent of sex differences in actual cognitive ability and national levels of masculinity‐femininity. Furthermore, international mean differences in general SEI could not be attributed to discrepancies in national intelligence quotient (IQ) levels or to cultural variations. 相似文献
