Validity of the emotional Stroop task hinges on equivalence between the emotion and the control words in terms of lexical features related to word recognition. The authors evaluated the lexical features of 1,033 words used in 32 published emotional Stroop studies. Emotion words were significantly lower in frequency of use, longer in length, and had smaller orthographic neighborhoods than words used as controls. These lexical features contribute to slower word recognition and hence are likely to contribute to delayed latencies in color naming. The often-replicated slowdown in color naming of emotion words may be due, in part, to lexical differences between the emotion and control words used in the majority of such studies to date. 相似文献

The objective of this paper was to describe the intellectual development of 39 children with HIV infection. The children received
serial evaluations over a 10-year period. Thirty-nine children were assessed with age-appropriate intellectual measures at
regular intervals as part of their treatment in the HIV Program of a children's hospital. Children showed an 24-point drop
in mean Bayley Mental scores over the first 2 years of life. McCarthy scores remained in the low average range from ages 3–5
years. IQ scores were stable by age 6 in the low average range, and unchanged through age 12. Significant changes in memory,
vocabulary, and performance subtests were noted. Children with HIV infection demonstrated a significant decline in mental
functioning over the first 2 years of life, fell into the low average range by age 3, and remained in the low average range,
with subtle changes in some areas. 相似文献

Socioeconomic status (SES) is strongly associated with cognitive ability and achievement during childhood and beyond. Little is known about the developmental relationships between SES and specific brain systems or their associated cognitive functions. In this study we assessed neurocognitive functioning of kindergarteners from different socioeconomic backgrounds, using tasks drawn from the cognitive neuroscience literature in order to determine how childhood SES predicts the normal variance in performance across different neurocognitive systems. Five neurocognitive systems were examined: the occipitotemporal/visual cognition system, the parietal/spatial cognition system, the medial temporal/memory system, the left perisylvian/language system, and the prefrontal/executive system. SES was disproportionately associated with the last two, with low SES children performing worse than middle SES children on most measures of these systems. Relations among language, executive function, SES and specific aspects of early childhood experience were explored, revealing intercorrelations and a seemingly predominant role of individual differences in language ability involved in SES associations with executive function. 相似文献

After training conditional discriminations among selected stimuli from two perceptual classes, the emergence of novel relations involving other members of both classes was assessed using cross-class probes. The cross-class probes were presented using one of four different testing schedules. In the 2/9 test, nine different probes were presented in each of two test blocks. In the 6/3 test, three different probes were presented in each of six test blocks. In the 18/1-RND test, each of the 18 cross-class probes was presented in separate test blocks. In the 2/9 and 6/3 tests, the cross-class probes were presented in a randomized order within test block. In the 18/1-RND test, the cross-class probes were presented in a randomized sequence. In the 18/1-PRGM test, however, the cross-class probes were presented in a programmed order (i.e., the values of the stimuli in each cross-class probe were changed systematically in the succession of probe presentations). About 55% of the linked perceptual classes emerged during the 2/9, 6/3, and 18/1-RND tests. Thus the number of different probes in a test block did not influence the emergence of classes as long as the probes were presented in a random order. Virtually all classes emerged during the 18/1-PRGM test. Thus at least one ordered introduction of different cross probes resulted in the reliable emergence of linked perceptual classes. Mechanisms responsible for linked perceptual class formation are discussed along with the relation of these classes to other complex categories. 相似文献

This paper is a response to Schumm's 2004 critique of Belkin's 2003 article, dealing with the "Don't Ask, Don't Tell" policy in the U.S. military. Schumm's critique specified four reasons for continuing to exclude homosexuals from military service: military effectiveness, sexual asymmetries, Christian soldiers' dilemma of "living a lie" and skewed opinions of policy makers and military elites. Each of these categories is analyzed and discussed. 相似文献

This study investigated whether cognitions and behavior in an asymmetric social dilemma can be predicted by national culture. Results indicated that, as predicted, groups of decision makers from Japan--a collectivist, hierarchical culture-were more cooperative, expected others to be more cooperative, and were more likely to adopt an equal allocation distribution rule to resolve the dilemma than were groups of decision makers from the United States-an individualist, egalitarian culture. An opportunity for communication had a greater impact on expectations of others' behavior in groups of U.S. decision makers than in groups of Japanese decision makers. 相似文献

Phonological sensitivity is an important causal variable in reading acquisition; however, there is controversy concerning its nature. One view holds that sensitivity to various linguistic units reflects independent abilities, whereas another holds sensitivity to these units reflects one ability. We examined relations among sensitivity to words, syllables, rhymes, and phonemes in 149 older preschool children (4- and 5-year-olds) and 109 younger preschool children (2- and 3-year-olds) who completed eight measures of phonological sensitivity and measures of print knowledge. Confirmatory factor analyses of all combinations of word, syllable, rhyme, and phoneme factors found that a one-factor model best explained the data from both groups of children (CFIs >.98). Only variance common to all phonological sensitivity skills was related to print knowledge and rudimentary decoding. Findings support a developmental conceptualization of phonological sensitivity. 相似文献

After continued pressure, the Canadian government offered an apology to Aboriginal peoples for its role in the Indian Residential School (IRS) system, where children were removed from their families in an effort to assimilate the Aboriginal population. Although the apology was sought after, it was unclear what Aboriginal peoples expected it to accomplish in relation to their treatment and quality of life within Canada. Quantitative and qualitative analyses revealed that, although Aboriginal adults (N = 164) felt the apology could potentially be a first step towards improved relations with the government and non‐Aboriginal Canadians, expectations that such changes would actually come to fruition were generally pessimistic. In exploring predictors of such expectations, path analysis indicated that those who had been intimately impacted by IRSs reported greater perceived discrimination that, in turn, was associated with lowered intergroup trust and forgiveness. Those who perceived high levels of discrimination were less likely to expect changes following the apology, which was mediated by the low levels of intergroup trust and forgiveness towards the government, but not towards non‐Aboriginal Canadians. Essentially, an apology was not enough to elicit hope for improved intergroup relations, especially when perceptions of continued discrimination impeded the restoration of intergroup trust and forgiveness. 相似文献

victims and offenders: accounts of paybacks,invulnerability, and financial gain among homeless youth
In recent years, club-drug use among a segment of urban gay men has gained in popularity, contributing to a range of effects, including heightened sexual stimulation, increased sexual performance and endurance, but also, unsafe sexual practices, drug overdose, drug addiction and death. This article draws from a larger study of urban sexual careers and identifies two prominent forms of club-drug use: the first, to facilitate sexual performance; and the second, to facilitate community. The author argues that the basis of both patterns of drug use lie in adaptations to the institutional organization of urban gay sexual sociality. 相似文献
