Executive function is a broad construct that encompasses various processes involved in goal‐directed behaviour in non‐routine situations (Banich, 2009). The present study uses a sample of 560 5‐ to 16‐year‐old twin pairs (M = 11.14, SD = 2.53): 219 monozygotic twin pairs (114 female; 105 male) and 341 dizygotic twin pairs (136 female, 107 male; 98 opposite sex) to extend prior literature by providing information about the factor structure and the genetic and environmental architecture of the Behavior Rating Inventory of Executive Function (BRIEF; Gioia et al., 2000, Child Neuropsychol., 6, 235; Gioia et al., 2000, Behavior rating inventory of executive function, Lutz, FL: Psychological Assessment Resources), a multifaceted rating scale of everyday executive functions. Phenotypic results revealed a 9‐scale, 3‐factor model best represents the BRIEF structure within the current sample. Results of the genetically sensitive analyses indicated the presence of rater bias/contrast effects for the Initiate, Working Memory, and Task‐Monitor scales. Additive genetic and non‐shared environmental influences were present for the Initiate, Plan/Organize, Organization of Materials, Shift, and Monitor and Self‐Monitor scales. Influences on Emotional Control were solely environmental. Interestingly, the aetiological architecture observed was similar to that of performance‐based measures of executive function. This observed similarity provided additional evidence for the usefulness of the BRIEF as a measure of ‘everyday’ executive function. 相似文献

Feeling the sting of another's injustice is a common human experience. We adopt a motivated information processing approach and explore how individual differences in social motives (e.g., high vs. low collectivism) and epistemic motives (e.g., high vs. low need for closure) drive individuals' evaluative and behavioral reactions to the just and unjust treatment of others. In two studies, one in the laboratory (N = 78) and one in the field (N = 163), we find that the justice treatment of others has a more profound influence on the attitudes and behaviors of prosocial thinkers, people who are chronically higher (vs. lower) in collectivism and lower (vs. higher) in the need for closure. In all, our results suggest that chronically higher collectivism and a lower need for closure work in concert to make another's justice relevant to personal judgment and behavior. 相似文献

Continuous bag of words (CBOW) and skip-gram are two recently developed models of lexical semantics (Mikolov, Chen, Corrado, & Dean, Advances in Neural Information Processing Systems, 26, 3111–3119, 2013). Each has been demonstrated to perform markedly better at capturing human judgments about semantic relatedness than competing models (e.g., latent semantic analysis; Landauer & Dumais, Psychological Review, 104(2), 1997 211; hyperspace analogue to language; Lund & Burgess, Behavior Research Methods, Instruments, & Computers, 28(2), 203–208, 1996). The new models were largely developed to address practical problems of meaning representation in natural language processing. Consequently, very little attention has been paid to the psychological implications of the performance of these models. We describe the relationship between the learning algorithms employed by these models and Anderson’s rational theory of memory (J. R. Anderson & Milson, Psychological Review, 96(4), 703, 1989) and argue that CBOW is learning word meanings according to Anderson’s concept of needs probability. We also demonstrate that CBOW can account for nearly all of the variation in lexical access measures typically attributable to word frequency and contextual diversity—two measures that are conceptually related to needs probability. These results suggest two conclusions: One, CBOW is a psychologically plausible model of lexical semantics. Two, word frequency and contextual diversity do not capture learning effects but rather memory retrieval effects. 相似文献

A pressing philosophical problem is how to respond to the existential, anxiety and disenchantment resulting from a naturalistic worldview that eschews transcendent foundations for meaning and value. This problem is becoming more urgent as the popularization of neuroscientific findings renders a disenchanted conception of human beings ever more vivid, compelling, and widespread. I argue that the study of transformative experiences occasioned by classic psychedelic drugs such as lysergic acid diethylamide and psilocybin may reveal the nature of a viable practical solution to this problem. Despite the apparent centrality of nonnaturalistic metaphysical apprehensions to psychedelic transformation, findings from psychedelic research suggest that key elements of psychedelic or “entheogenic” spirituality are consistent with naturalism. These include disruption to neurocognitive mechanisms underpinning the sense of self, and consequent experiences of self‐transcendence and of the decoupling of attention from personal concerns. This liberation of attention can result in the availability of broader perspectives and the development of wonder and appreciation for life. 相似文献

Evidence Supporting Pre‐University Effects Hypotheses of Women's Underrepresentation in Philosophy 下载免费PDF全文
Chris Dobbs 《希帕蒂亚:女权主义哲学杂志》2017,32(4):940-945
In this short essay, I report results from a representative national dataset (n > 7,300) from the Cooperative Institutional Research Program that shows that significantly more men than women intend to major in philosophy at the high‐school and pre‐university level. This lends credence to pre‐university effects hypotheses of women's underrepresentation in philosophy and successfully replicates a smaller analysis performed by Cheshire Calhoun at Colby College in 2009. I also defend my analysis against an objection that claims that intention to major is not a good predictor of final major selection. Finally, I argue that this new analysis should lead to further investment in university‐level diversity programs. 相似文献

Implicit sequence learning is thought to be preserved in aging when the to-be learned associations are first-order; however, when associations are second-order, older adults (OAs) tend to experience deficits as compared to young adults (YAs). Two experiments were conducted using a first (Experiment 1) and second-order (Experiment 2) serial-reaction time task. Stimuli were presented at a constant rate of either 800 milliseconds (fast) or 1200 milliseconds (slow). Results indicate that both age groups learned first-order dependencies equally in both conditions. OAs and YAs also learned second-order dependencies, but the learning of lag-2 information was significantly impacted by the rate of presentation for both groups. OAs showed significant lag-2 learning in slow condition while YAs showed significant lag-2 learning in the fast condition. The sensitivity of implicit sequence learning to the rate of presentation supports the idea that OAs and YAs different processing speeds impact the ability to build complex associations across time and intervening events. 相似文献

Non‐Arbitrariness in Mapping Word Form to Meaning: Cross‐Linguistic Formal Markers of Word Concreteness 下载免费PDF全文
Arbitrary symbolism is a linguistic doctrine that predicts an orthogonal relationship between word forms and their corresponding meanings. Recent corpora analyses have demonstrated violations of arbitrary symbolism with respect to concreteness, a variable characterizing the sensorimotor salience of a word. In addition to qualitative semantic differences, abstract and concrete words are also marked by distinct morphophonological structures such as length and morphological complexity. Native English speakers show sensitivity to these markers in tasks such as auditory word recognition and naming. One unanswered question is whether this violation of arbitrariness reflects an idiosyncratic property of the English lexicon or whether word concreteness is a marked phenomenon across other natural languages. We isolated concrete and abstract English nouns (N = 400), and translated each into Russian, Arabic, Dutch, Mandarin, Hindi, Korean, Hebrew, and American Sign Language. We conducted offline acoustic analyses of abstract and concrete word length discrepancies across languages. In a separate experiment, native English speakers (N = 56) with no prior knowledge of these foreign languages judged concreteness of these nouns (e.g., Can you see, hear, feel, or touch this? Yes/No). Each naïve participant heard pre‐recorded words presented in randomized blocks of three foreign languages following a brief listening exposure to a narrative sample from each respective language. Concrete and abstract words differed by length across five of eight languages, and prediction accuracy exceeded chance for four of eight languages. These results suggest that word concreteness is a marked phenomenon across several of the world's most widely spoken languages. We interpret these findings as supportive of an adaptive cognitive heuristic that allows listeners to exploit non‐arbitrary mappings of word form to word meaning. 相似文献
