Research on academic learning indicates that many students experience major difficulties with introductory statistics and
methodology courses. We hypothesized that students’ difficulties may depend in part on the fact that statistics tasks are
commonly viewed as related to the threatening domain of math. In two field experiments which we carried out in the ecological
context of introductory statistics courses, the representation of a statistics task administered to undergraduate students
in Psychology (Study 1; n = 127) and Biology (Study 2; n = 166) was manipulated. In both studies we found that students who reported the least favorable prior attainments in math
had their performance thwarted when the task was presented as related to the math domain, whereas no performance impairment
was observed when the task was presented as related to the verbal/linguistic domain. Implications of the findings for the
design and delivery of introductory statistics and research methodology courses are discussed.

Two experiments investigated whether dealing with a homogeneous subset of syllogisms with time-constrained responses encouraged participants to develop and use heuristics for abstract (Experiment 1) and thematic (Experiment 2) syllogisms. An atmosphere-based heuristic accounted for most responses with both abstract and thematic syllogisms. With thematic syllogisms, a weaker effect of a belief heuristic was also observed, mainly where the correct response was inconsistent with the atmosphere of the premises. Analytic processes appear to have played little role in the time-constrained condition, whereas their involvement increased in a self-paced, unconstrained condition. From a dual-process perspective, the results further specify how task demands affect the recruitment of heuristic and analytic systems of reasoning. Because the syllogisms and experimental procedure were the same as those used in a previous neuroimaging study by Goel, Buchel, Frith, and Dolan (2000), the result also deepen our understanding of the cognitive processes investigated by that study. 相似文献

In the last two decades, comparative research has addressed the issue of how the global and local levels of structure of visual stimuli are processed by different species, using Navon-type hierarchical figures, i.e. smaller local elements that form larger global configurations. Determining whether or not the variety of procedures adopted to test different species with hierarchical figures are equivalent is of crucial importance to ensure comparability of results. Among non-human species, global/local processing has been extensively studied in tufted capuchin monkeys using matching-to-sample tasks with hierarchical patterns. Local dominance has emerged consistently in these New World primates. In the present study, we assessed capuchins’ processing of hierarchical stimuli with a method frequently adopted in studies of global/local processing in non-primate species: the conflict–choice task. Different from the matching-to-sample procedure, this task involved processing local and global information retained in long-term memory. Capuchins were trained to discriminate between consistent hierarchical stimuli (similar global and local shape) and then tested with inconsistent hierarchical stimuli (different global and local shapes). We found that capuchins preferred the hierarchical stimuli featuring the correct local elements rather than those with the correct global configuration. This finding confirms that capuchins’ local dominance, typically observed using matching-to-sample procedures, is also expressed as a local preference in the conflict–choice task. Our study adds to the growing body of comparative studies on visual grouping functions by demonstrating that the methods most frequently used in the literature on global/local processing produce analogous results irrespective of extent of the involvement of memory processes. 相似文献

Both general and math-specific anxiety are related to proficiency in mathematics. However, it is not clear when math anxiety arises in young children, nor how it relates to early math performance. This study therefore investigated the early association between math anxiety and math performance in Grades 2 and 3, by accounting for general anxiety and by further inspecting the prevalent directionality of the anxiety–performance link. Results revealed that this link was significant in Grade 3, with a prevalent direction from math anxiety to performance, rather than the reverse. Longitudinal analyses also showed an indirect effect of math anxiety in Grade 2 on subsequent math performance in Grade 3. Overall, these findings highlight the importance of monitoring anxiety from the early stages of schooling in order to promote proficient academic performance. 相似文献

The current study examined the mediating role of adolescents' personal values on the relation between maternal and peer expectations for prosocial behaviors and adolescents' self-reported prosocial and antisocial behaviors. One hundred thirty-four adolescents (mean age = 16.22 years, 54% girls) completed measures of their own values and behaviors, as well as their perceptions of the positive expectations that their mother and their best friend(s) had for their (the adolescents') prosocial behaviors. Stepwise regression analyses suggested that adolescents' personal prosocial values mediated the relation between adolescents' perceptions of both maternal and peer expectations and adolescents' prosocial behaviors. In addition, for boys, perceptions of positive peer expectations were directly and negatively related to antisocial behaviors. The current study has important implications for parents, educators, and practitioners who are concerned about promoting adolescents' positive behaviors and discouraging negative behaviors. 相似文献

Numerical fractions are commonly used to express ratios and proportions (i.e., real numbers), but little is known about how they are mentally represented and processed by skilled adults. Four experiments employed comparison tasks to investigate the distance effect and the effect of the spatial numerical association of response codes (SNARC) for fractions. Results showed that fractions were processed componentially and that the real numerical value of the fraction was not accessed, indicating that processing the fraction's magnitude is not automatic. In contrast, responses were influenced by the numerical magnitude of the components and reflected the simple comparison between numerators, denominators, and reference, depending on the strategy adopted. Strategies were used even by highly skilled participants and were flexibly adapted to the specific experimental context. In line with results on the whole number bias in children, these findings suggest that the understanding of fractions is rooted in the ability to represent discrete numerosities (i.e., integers) rather than real numbers and that the well-known difficulties of children in mastering fractions are circumvented by skilled adults through a flexible use of strategies based on the integer components. 相似文献

The spatial Simon effect is often asymmetric, being greater on one side than on the other. To date, not much attention has
been paid to these asymmetries, and explanations of the Simon effect do not take them into account. In the present article,
we attempt to clarify the statistical implications of the asymmetries so as to provide a useful tool for future empirical
investigation. Starting with examples from our laboratory and previous well-known studies, we point out the consequences of
ignoring the asymmetries in the Simon effect. We suggest an alternative data analysis that might render the results clearer.
Finally, through a comparison of left- and right-handed subjects, we demonstrate that asymmetries in the Simon effect are
linked to the lateralization of processes involved in the Simon task—that is, attention and response selection. This approach
provides a strong argument against collapsing data from the two sides to measure the Simon effect. 相似文献
