A long-standing debate surrounds the issue of whether human and nonhuman animals share the same perceptual mechanisms. In humans, the Zöllner illusion occurs when two parallel lines appear to be convergent when oblique crosshatching lines are superimposed. Although one baboon study suggests that they too might perceive this illusion, the results of that study were unclear, whereas two recent studies suggest that birds see this illusion in the opposite direction from humans. It is currently unclear whether these mixed results are an artifact of the experimental design or reflect a peculiarity of birds’ visual system or, instead, a wider phenomenon shared among nonhuman mammals. Here, we trained 6 monkeys to select the narrower of two gaps at the end of two convergent lines. Three different conditions were set up: control (no crosshatches), perpendicular (crosshatches not inducing the illusion), and Zöllner (crosshatches inducing the illusion in humans). During training, the degrees of convergence between the two lines ranged from 15° to 12°. Monkeys that reached the training criterion were tested with more difficult discriminations (11°–1°), including probe trials with parallel lines (0°). The results showed that monkeys perceived the Zöllner illusion in the same direction as humans. Comparison of these data with the data from bird studies points toward the existence of different orientation-tuned mechanisms between primate and nonprimate species. 相似文献

Developmental dyscalculia (DD) is marked by specific deficits in processing numerical and mathematical information despite normal intelligence (IQ) and reading ability. We examined how brain circuits used by young children with DD to solve simple addition and subtraction problems differ from those used by typically developing (TD) children who were matched on age, IQ, reading ability, and working memory. Children with DD were slower and less accurate during problem solving than TD children, and were especially impaired on their ability to solve subtraction problems. Children with DD showed significantly greater activity in multiple parietal, occipito‐temporal and prefrontal cortex regions while solving addition and subtraction problems. Despite poorer performance during subtraction, children with DD showed greater activity in multiple intra‐parietal sulcus (IPS) and superior parietal lobule subdivisions in the dorsal posterior parietal cortex as well as fusiform gyrus in the ventral occipito‐temporal cortex. Critically, effective connectivity analyses revealed hyper‐connectivity, rather than reduced connectivity, between the IPS and multiple brain systems including the lateral fronto‐parietal and default mode networks in children with DD during both addition and subtraction. These findings suggest the IPS and its functional circuits are a major locus of dysfunction during both addition and subtraction problem solving in DD, and that inappropriate task modulation and hyper‐connectivity, rather than under‐engagement and under‐connectivity, are the neural mechanisms underlying problem solving difficulties in children with DD. We discuss our findings in the broader context of multiple levels of analysis and performance issues inherent in neuroimaging studies of typical and atypical development. 相似文献

Feminist epistemologies consider ways in which gender (among other social factors) influences knowledge. In this article, I want to consider a particular kind of feminist empiricism that has been called feminist radical empiricism (where the empiricism, not the feminism, is radical). I am particularly interested in this view's treatment of values as empirical, and consequently up for revision on the basis of empirical evidence. Proponents of this view cite the fact that it allows us to talk about certain things such as racial and gender equality as objective facts: not just whether we have achieved said equality in our society, but whether we are, in fact, all equal. I will raise the concern that the way in which they model the role of values in epistemology may be a problematic idealization of the open‐mindedness of human agents. In some cases, resistance to value‐change cannot be diagnosed as a failure to respond adequately to evidence. If so, the strategy of empirically testing our values that some feminist radical empiricists suggest may not be as useful a tool for social change as they think. 相似文献

This article examines cross-cultural therapeutic assessment in a community mental health clinic. The first case describes the work between a Caucasian assessor and a Mexican American family. The authors explore the metaphorical and literal translation of the findings from English to Spanish and the parallel process of translation of the self, experienced by both assessor and client. The second case describes the work between a Caucasian assessor and an African American adolescent. We describe the inherent challenge between the Eurocentric "task" orientation of the evaluation and the Afrocentric "relationship" orientation. We suggest that bridging the gap between cultures and overcoming cultural mistrust lay in the building of the assessor-client relationship. Fischer's concepts of rapport and intimacy are emphasized and expanded on as we emphasize the importance of cocreated meaning in cross-cultural assessment work. 相似文献

The present study investigated the lexical representations underlying the production of English schwa words. Two types of schwa words were compared: words with a schwa in poststress position (e.g., mackerel), whose schwa and reduced variants differ in a categorical way, and words with a schwa in prestress position (e.g., salami), whose variants differ in a noncategorical way. Participants named pseudohomophones and matched pseudowords corresponding to schwa and reduced variants of these words. Results revealed an advantage for pseudohomophones over matched pseudowords for both variants of poststress schwa words but only for schwa variants of prestress schwa words. As the pseudohomophone advantage is assumed to reflect the activation of a phonologically matching stored phonological representation, these results suggest that both variants of poststress schwa words are lexically represented while only schwa variants of prestress schwa words are. This result extends the proposal that words with two categorically distinct variants are stored in the production lexicon with 2 representations to another language and demonstrates that this 2-lexeme account does not generalize to pronunciation variants differing from one another in a noncategorical fashion. This finding challenges one of the widely shared assumption of generative models of word production: that content words have only 1 phonological representation. On the other hand, it provides further evidence in favor of another fundamental assumption of these models: that lexical representations are abstract sets of segments rather than fully detailed exemplars. 相似文献

This study examined 219 African American college students at predominantly White universities using the constructs of perfectionism, academic achievement, self-esteem, depression, and racial identity. Cluster analysis was performed using the Almost Perfect Scale-Revised (APS-R), which yielded three clusters that represented adaptive perfectionists, maladaptive perfectionists, and nonperfectionists. These three groups were compared on their scores on the Rosenberg Self-Esteem Scale (RSES), the Center for Epidemiological Studies-Depression Scale (CES-D), the Cross Racial Identity Scale (CRIS), and Grade Point Average (GPA). Adaptive perfectionists reported higher self-esteem and lower depression scores than both the nonperfectionists and maladaptive perfectionists. Adaptive perfectionists had higher GPAs than nonperfectionists. On the racial identity scales, maladaptive perfectionists had higher scores on Pre-Encounter Self Hatred and Immersion-Emersion Anti-White subscales than adaptive perfectionists. The cultural and counseling implications of this study are discussed and integrated. Finally, recommendations are made for future studies of African American college students and perfectionism. 相似文献

This study examined the lexical representations and psycholinguistic mechanisms underlying the production and recognition of novel words with two pronunciation variants in French. Participants first learned novel schwa words (e.g., /??nyk/), which varied in their alternating status (i.e., whether these words were learned with one or two variants) and, for alternating words, in the frequency of their variants. They were then tested in picture-naming (free or induced) and recognition memory tasks (i.e., deciding whether spoken items were learned during the experiment or not). Results for free naming show an influence of variant frequency on responses, more frequent variants being produced more often. Moreover, our data show an effect of the alternating status of the novel words on naming latencies, with longer latencies for alternating than for nonalternating novel words. These induced naming results suggest that both variants are stored as lexical entries and compete during the lexeme selection process. Results for recognition show an effect of variant frequency on reaction times and no effect of variant type (i.e., schwa versus reduced variant). Taken together, our findings suggest that participants both comprehend and produce novel French schwa words using two lexical representations, one for each variant. 相似文献

This study aims to demonstrate the effect of action fluency on emotional evaluation, specifically to show that neutral words can be evaluated positively or negatively depending on motor activity and evaluative setting. Right-handers naturally tend to associate positive (negative) valence to the right (left) part of space (Casasanto, 2009). We extend these associations to lateralized behaviors by studying the combined effect of motor fluency of lateral arm movements and the evaluative scale on the subjective evaluation of neutral words. Three experiments evidenced that, for right-handers, the realization of fluent rightward arm movements and the use of an evaluative scale congruent with their valence/laterality associations (left negative, right positive) led to a positive evaluation of neutral words, while non-fluent leftward movements and an incongruent scale led to a negative evaluation. This study demonstrates that emotion–action associations are experience-based, and influenced by functional and situational constraints. 相似文献
