Deviances in early event-related potential (ERP) components reflecting auditory and phonological processing are well-documented in children at familial risk for dyslexia. However, little is known about brain responses which index processing in other linguistic domains such as lexicon, semantics and syntax in this group. The present study investigated effects of lexical-semantic priming in 20- and 24-month-olds at-risk for dyslexia and typically developing controls in two ERP experiments. In both experiments an early component assumed to reflect facilitated lexical processing for primed words was enhanced in the at-risk group compared to the control group. Moreover, an N400-like response which was prominent in the control group was attenuated or absent in at-risk children. Results suggest that deficiencies in young children at-risk for dyslexia are not restricted to perceptual and lower-level phonological abilities, but also affect higher order linguistic skills such as lexical and semantic processing. 相似文献

In this study, we systematically review the scientific literature on the effect of color on object recognition. Thirty-five independent experiments, comprising 1535 participants, were included in a meta-analysis. We found a moderate effect of color on object recognition (d = 0.28). Specific effects of moderator variables were analyzed and we found that color diagnosticity is the factor with the greatest moderator effect on the influence of color in object recognition; studies using color diagnostic objects showed a significant color effect (d = 0.43), whereas a marginal color effect was found in studies that used non-color diagnostic objects (d = 0.18). The present study did not permit the drawing of specific conclusions about the moderator effect of the object recognition task; while the meta-analytic review showed that color information improves object recognition mainly in studies using naming tasks (d = 0.36), the literature review revealed a large body of evidence showing positive effects of color information on object recognition in studies using a large variety of visual recognition tasks. We also found that color is important for the ability to recognize artifacts and natural objects, to recognize objects presented as types (line-drawings) or as tokens (photographs), and to recognize objects that are presented without surface details, such as texture or shadow. Taken together, the results of the meta-analysis strongly support the contention that color plays a role in object recognition. This suggests that the role of color should be taken into account in models of visual object recognition. 相似文献

Using confirmatory factor analyses, we examined method effects on Rosenberg's Self-Esteem Scale (RSES; Rosenberg, 1965) in a sample of older European adults. Nine hundred forty nine community-dwelling adults 60 years of age or older from 5 European countries completed the RSES as well as measures of depression and life satisfaction. The 2 models that had an acceptable fit with the data included method effects. The method effects were associated with both positively and negatively worded items. Method effects models were invariant across gender and age, but not across countries. Both depression and life satisfaction predicted method effects. Individuals with higher depression scores and lower life satisfaction scores were more likely to endorse negatively phrased items. 相似文献

There are two ways that we might respond to the underdetermination of theory by data. One response, which we can call the agnostic response, is to suspend judgment: “Where scientific standards cannot guide us, we should believe nothing”. Another response, which we can call the fideist response, is to believe whatever we would like to believe: “If science cannot speak to the question, then we may believe anything without science ever contradicting us”. C.S. Peirce recognized these options and suggested evading the dilemma. It is a Logical Maxim, he suggests, that there could be no genuine underdetermination. This is no longer a viable option in the wake of developments in modern physics, so we must face the dilemma head on. The agnostic and fideist responses to underdetermination represent fundamentally different epistemic viewpoints. Nevertheless, the choice between them is not an unresolvable struggle between incommensurable worldviews. There are legitimate considerations tugging in each direction. Given the balance of these considerations, there should be a modest presumption of agnosticism. This may conflict with Peirce's Logical Maxim, but it preserves all that we can preserve of the Peircean motivation. 相似文献

The present essay takes as its point of departure the resurgence of the anti-porn argument claiming that pornography is harmful. It focuses especially on philosopher Rae Langton’s attempt to use speech act theory to defend the anti-porn position of Catherine MacKinnon. Langton’s argument is critiqued for assuming that we can ascertain the function of pornography without considering the situations of its use. It hence runs counter to the particularizing intent of speech act theory as such, which emphasizes the need to study speech in context. Rather than dismiss the anti-porn position Langton defends as faulty, the essay suggests that it remains an incontrovertible facet of the pornographic situation, and as such should be dialectically engaged. In the second half of the essay, therefore, the reasoning that informs the antiporn position is shown to be incompatible with the recurrent claim that porn is the expression of a male desire to dominate women. Rather, a closer look at Langton’s defense of the anti-porn argument helps us see that pornography is the expression of cognitive possibilities unique to the historical conditions that have brought it forth, and as such is every bit as self-conflicting as is capitalism itself. 相似文献

Nineteen upper-middle class, pre-marital, college couples volunteered to participate in a study on interpersonal relationships. Couples received a modified Rorschach, thematic test, Marriage Value Inventory, a sex questionnaire, and an intensive depth interview. A Q sort of 100 personality items was used to assess the Ss. It was hypothesized that couples would show smaller discrepancies than randomized pairs, except for items relating to dominance, dependency, nurturance, exhibitionism, masculinity and femininity, where the reverse was predicted. Results confirmed the homogamy prediction, but only the dependency need was significant of the complementary predictions. Perception scores and expressive behavior are seen as potential adjuncts to questionnaires and inventories in predicting marital choice. 相似文献

The present study investigates the effects of psychological hardiness and successful completion of a rigorous 250‐km ski march over 9 days in Arctic winter conditions. This ski march is the final portion of a selection program for border rangers in the Norwegian Armed Forces. Study participants were N = 178 soldiers with a mean age of 19.9 years (range 18–23). Hierarchical regression results showed that successful completion of the ski march was predicted by total hardiness scores, after controlling for nutrition factors, physical fitness and sensation seeking. A second hierarchical regression found that the commitment facet of hardiness was the most significant predictor of ski march success, again controlling for nutrition, physical fitness and sensation seeking. Analyses of daily participant surveys showed that the high commitment group reported the highest levels of positive daily coping, and also evaluated their performance more positively. This group also showed increasingly positive self‐evaluations as the exercise went on. Together, these results indicate that hardiness commitment is a key factor influencing performance in a rigorous and stressful endurance task requiring sustained effort, perhaps by enhancing active coping skills and self‐efficacy beliefs. 相似文献
