Fire interest is a risk factor for firesetting. This study tested whether a fire-specific emotional Stroop task can effectively
measure an information-processing bias for fire-related stimuli. Clinic-referred and nonreferred adolescents (aged 13–16 years)
completed a pictorial “Fire Stroop,” as well as a self-report fire interest questionnaire and several control tasks. Results
showed (a) comparatively greater fire-specific attentional bias among referred adolescent firesetters, (b) a negative relationship
between Fire Stroop attentional bias and self-reported fire interest, and (c) positive correspondence between Fire Stroop
attentional bias and self-reported firesetting frequency. These findings suggest that instruments that measure an automatic
bias for fire-specific stimuli may usefully supplement self-report measures in the assessment and understanding of firesetting
behavior. 相似文献

Different aspects of early sleep organization have been associated with subsequent development in premature infants. The aim of the present study was to assess the relations between rapid eye movement (REM) activity in premature neonates and infants' developmental outcomes at 6 months. Participants were 81 premature infants (47 males). Sleep-wake states and REM were observed across 4 consecutive evening hours (7-11 PM) in 10-s frames when infants were between 32 and 36 weeks post-menstrual age. Developmental outcome was assessed at 6 months with the mental development index (MDI) of the Bayley II. Infants with low-REM activity spent more time in less growth-promoting states, including crying and unfocused alert states in the neonatal period and had lower MDI scores at 6 months corrected age compared to infants with high-REM. Differences between the high- and low-REM groups were independent of neonatal medical risk. Low-REM activity may serve as an indicator of developmental risk among premature neonates. 相似文献

Many studies have suggested that a word’s orthographic form must be processed before its meaning becomes available. Some interpret
the (null) finding of equal facilitation after semantically transparent and opaque morphologically related primes in early
stages of morphological processing as consistent with this view. Recent literature suggests that morphological facilitation
tends to be greater after transparent than after opaque primes, however. To determine whether the degree of semantic transparency
influences parsing into a stem and a suffix (morphological decomposition) in the forward masked priming variant of the lexical
decision paradigm, we compared patterns of facilitation between semantically transparent (e.g., coolant—cool) and opaque (e.g., rampant—ramp) prime—target pairs. Form properties of the stem (frequency, neighborhood size, and prime—target letter overlap), as well
as related—unrelated and transparent—opaque affixes, were matched. Morphological facilitation was significantly greater for
semantically transparent pairs than for opaque pairs. Ratings of prime—target relatedness predicted the magnitude of facilitation.
The results limit the scope of form-then-meaning models of word recognition and demonstrate that semantic similarity can influence
even early stages of morphological processing. The research reported here was supported by National Institute of Child Health
and Development Grant HD-01994 to Haskins Laboratories. 相似文献

Human development is thought to evolve from the dynamic interchange of biological dispositions and environmental provisions; yet the effects of specific biological and environmental birth conditions on the trajectories of cognitive and social‐emotional growth have rarely been studied. We observed 126 children at six time‐points from birth to 5 years. Intelligence, maternal sensitivity, and child social engagement were repeatedly tested. Effects of neonatal vagal tone (VT) and maternal postpartum depressive symptoms on growth‐rates were assessed. Cognitive development showed a substantial growth‐spurt between 2 and 5 years and social engagement increased rapidly across the first year and more gradually thereafter. VT improved cognitive and social‐emotional growth‐rates across the first year, whereas maternal depressive symptoms interfered with growth from 2 to 5 years. Differences between infants with none, one, or two non‐optimal birth conditions increased with age. Findings shed light on the dynamics of early development as it is shaped by biological and environmental initial conditions. 相似文献

Are Nativists a Different Kind of Democrat? Democratic Values and “Outsiders” in Japan 总被引:1,自引:0,他引:1
This paper combines three elements: a discussion of democratic values and the status of outsiders in Japanese political culture, the development of new measures to examine sensitive issues of nativism and foreigner perception in Japan, and an empirical exploration of the relationship between democratic values and antipathy toward outsiders. Two forms of democratic orientation were investigated in a sample of about 1,000 university students in Japan: a defensive version, which adheres to the formalistic requirements of democracy but is exclusionary and illiberal, and a universalist version that is liberal and tolerant. A defensive orientation is associated with greater chauvinism, a greater sense of threat emanating from foreigners, and a heightened anxiety about economic competition. A universalist orientation is associated with low perceived threat and low chauvinism, a lack of fear of economic competition, and a positive view of the cultural contributions of outsiders. Nativism may indeed be compatible with democratic values, but only with the defensive, exclusionary form. In short, the defensive form is democracy for xenophobes. Such an orientation is not unique to Japan, but is likely to be found in developing democracies as well as in advanced democracies that feel threatened. 相似文献

This study evaluated peer incidental teaching as a strategy for increasing reciprocal peer interactions by children with autism. Three typical preschoolers were trained as peer tutors for 3 young children with autism. During a classroom free-play session, peer tutors used incidental teaching to obtain verbal labels of preferred toys by children with autism. A multiple baseline across the 3 target children showed replicated positive effects of the intervention. Adult supervision and assistance were then faded systematically, with resulting maintenance of increased reciprocal interactions. Multiple measures of the extent and limits of generalization suggested that 1 child increased interactions in free-play periods throughout the day, but none of the children showed increases at lunch. Teacher and peer ratings supported the social validity of positive findings. 相似文献

This study investigated the relationship between four types of parenting behaviour—warmth, control, monitoring, and autonomy-promoting—and two components of ethnic identity—ethnic behaviours/knowledge and ethnic pride—in first- and second-generation Chinese-American and Chinese-Australian high school students. As hypothesized, parenting behaviours did not predict levels of ethnic behaviour/knowledge, but ethnic pride was associated with family environments characterized as warm, controlling, and autonomy-promoting. Neither gender of respondent nor geographical location (United States or Australia) added significantly to the variance in ethnic identity. The study indicates that parenting practices contribute significantly to adolescents' sense of pride and positive evaluation of their ethnic heritage. 相似文献

The effects of selective cholinergic cell loss within the basal forebrain (BF) were determined using a task that requires shifting of attention between two visual stimuli. Discriminability between two stimuli and response bias were determined in young and old F-344 rats given BF injections of IgG-192 saporin (100 ng). The lesion reduced ChAT activity in the frontal and parietal cortices, hippocampus, and olfactory bulbs. The lesion did not significantly alter Na+/K+-ATPase activity in cortex, hippocampus, or olfactory bulbs, or endogenous levels of neuropeptide Y and neurokinin B within the BF. The BF lesions impaired both stimulus discriminability and response bias in young and old rats. The BF lesions had a significantly greater effect upon stimulus discriminability and response bias in aged rats, compared to young rats, only when the stimulus duration was very brief, i.e., when the task was most difficult to solve. At longer stimulus durations, aging and lesions showed no interaction. The results suggest that the selective loss of cholinergic cells in the BF, but not normal aging, impairs the ability to discriminate between independent sensory stimuli. The loss of these cells confers a response bias in simple operant tasks involving motor responses to reward-related visual stimuli. 相似文献

In the last decade, some feminist epistemologists have suggested that the global scepticism which results from the Cartesian dream argument is the product of a self-consciously masculine modern era, whose philosophy gave pride of place to the individual cognizer, disconnected from the object of knowledge, from other knowers, indeed from his own body. Lorraine Code claims that under a conception of a cognizer as an essentially social being, Cartesian scepticism would not arise. I argue that this is false: an argument parallel in structure, and as well supported as the first-person Cartesian dream argument, could arise in an epistemology which recognizes the social nature of human life and knowledge. Against Code, it is not the first-personhood of Cartesianism which generates scepticism. A second-person scepticism could emerge in a socially conscious epistemology. 相似文献
