In a paper published in this journal, a possible QTL association was reported between general cognitive ability and a marker, identified by an expressed sequence tag, EST00083 (Skuder et al., 1995). In two small samples, the frequency of the common allele of this DNA marker, which was shown to be in the threonine transfer RNA gene in mitochondrial DNA, was significantly greater in a high-IQ group than in a low-IQ group. As part of the ongoing IQ QTL Project (Plomin et al., 1995), we have attempted to replicate this QTL association. First, we found that the QTL association remained significant when we compared 51 high- and 51 -average IQ subjects, drawn in part from the samples used in the previous report. However, when we examined the association in new samples of 40 extremely high-IQ subjects and 50 average-IQ subjects, the association did not replicate. This underlies the need for replication in case-control studies of allelic association. 相似文献

There is a dearth of suitable metrics capable of objectively quantifying motor competence. Further, objective movement quality characteristics during free play have not been investigated in pre-school children. The aims of this study were to characterize children's free play physical activity and investigate how gait quality characteristics cluster with free play in pre-school children (3–5 years old). Sixty-one children (39 boys; 4.3 ± 0.7 years, 1.04 ± 0.05 m, 17.8 ± 3.2 kg) completed the movement assessment battery for children and took part in free play while wearing an ankle- and hip-mounted accelerometer. Characteristics of movement quality were profiled using a clustering algorithm. Spearman's rho and the Mann-Whitney U tests were used to assess relationships between movement quality characteristics and motor competence classification differences in integrated acceleration and spectral purity, respectively. Significant differences were found between motor competency classifications for spectral purity and integrated acceleration (p < .001). Spectral purity was hierarchically clustered with motor competence and integrated acceleration. Significant positive correlations were found between spectral purity, integrated acceleration and motor competence (p < .001). This is the first study to report spectral purity in pre-school children and the results suggest that the underlying frequency component of movement is clustered with motor competence. 相似文献

There is a lack of validated measures for assessing self-awareness of deficits after pediatric traumatic brain injury (TBI). The current study aimed to develop and examine the psychometric properties of the Paediatric Awareness Questionnaire (PAQ), and investigate factors related to self-awareness. The PAQ was administered to 32 children aged 8–16 years with mild to severe TBI (72% male, M age = 11.75, SD = 2.9), their parents, and treating clinicians, and to 32 age- and gender-matched typically developing controls and their parents. Children with TBI and their parents also completed the Knowledge of Injury Checklist (KIC), and parents completed the Depression Anxiety and Stress Scale 21. The PAQ was found to have fair to excellent (α = .79–.97) internal consistency for all versions across both groups and good concordance between parent and clinician total scores (ICC = .78). There was also evidence of convergent validity between the PAQ and KIC for both child (r = ?.45, p < .05) and parent ratings (r = ?.66, p < .001). Poorer self-awareness was significantly related to younger age at injury for the TBI group and lower parental education for the total sample. ANCOVA identified that children with TBI demonstrated significantly poorer awareness than controls after controlling for parental education. Children with TBI typically overestimated their functioning compared to their parents, whereas typically developing children tended to rate their functioning lower than their parents. These findings provide preliminary support for the reliability and validity of the PAQ for assessing self-awareness after pediatric TBI. 相似文献

Research suggests that the human brain codes manipulable objects as possibilities for action, or affordances, particularly objects close to the body. Near-body space is not only a zone for body-environment interaction but also is socially relevant, as we are driven to preserve our near-body, personal space from others. The current, novel study investigated how close proximity of a stranger modulates visuomotor processing of object affordances in shared, social space. Participants performed a behavioural object recognition task both alone and with a human confederate. All object images were in participants’ reachable space but appeared relatively closer to the participant or the confederate. Results revealed when participants were alone, objects in both locations produced an affordance congruency effect but when the confederate was present, only objects nearer the participant elicited the effect. Findings suggest space is divided between strangers to preserve independent near-body space boundaries, and in turn this process influences motor coding for stimuli within that social space. To demonstrate that this visuomotor modulation represents a social phenomenon, rather than a general, attentional effect, two subsequent experiments employed nonhuman joint conditions. Neither a small, Japanese, waving cat statue (Experiment 2) nor a metronome (Experiment 3) modulated the affordance effect as in Experiment 1. These findings suggest a truly social explanation of the key interaction from Experiment 1. This study represents an important step toward understanding object affordance processing in real-world, social contexts and has implications broadly across fields of social action and cognition, and body space representation. 相似文献

Several studies have observed heightened Pavlovian fear conditioning in PTSD. However, it is unclear how fear conditioning in PTSD is related to risk factors for the disorder, such as anxiety sensitivity. Fifty-one combat-exposed veterans (20 with PTSD, 31 without PTSD) completed a differential fear conditioning task in which one colored rectangle (CS +) predicted a loud scream (US), whereas a different colored rectangle (CS-) predicted no US. Veterans with PTSD were characterized by greater anxiety to the CS + but not the CS- during acquisition and extinction, and greater US expectancy during the CS + but not the CS- at extinction. Also, veterans with PTSD had greater pupil dilation to both CSs at extinction, but not at acquisition. Anxiety sensitivity was correlated with anxiety and US expectancy in response to the CS +, but not the CS-, at both acquisition and extinction, and also with pupil diameter to both the CS + and CS- at extinction. Nearly all of these relations held when covarying for PTSD symptoms and trait anxiety. These findings suggest that increased fear conditioning in PTSD may be related to elevated anxiety sensitivity. 相似文献

The purpose of this study was to explore how microaggressions affect counseling outcomes. Participants were 128 racial/ethnic minority individuals who had been in counseling within the past year. Results indicated that identity attributions were associated with counseling outcomes (i.e., working alliance and perceived improvement in counseling). Furthermore, perceptions of cultural humility mediated the relationship between negative emotion due to rupture and counseling outcomes (i.e., working alliance and perceived improvement in counseling). 相似文献

In this paper, I consider Adorno's claim that art is at, or is coming to, an ‘end’. I consider Adorno's account in relation to the work of Arthur Danto and G. W. F. Hegel. I employ Danto's account, together with two distinct interpretive glosses of Hegel's account, as heuristic devices in order to clarify both Adorno's own arguments, and the context within which they are being advanced. I argue that while Danto and Hegel see art as coming to an end autonomously, owing to art's successful realization of its governing principle, Adorno by contrast sees art as coming to an end heteronomously. Art's narrative is forcibly broken off, rather than completed. Adorno's account, indebted to Hegel, of art's commitment both to autonomy and the realization of ‘spiritual needs’ is explored in order to clarify how, on Adorno's view, this has happened to art; and why, precisely, he believes art is coming to an end. 相似文献

This paper offers a new interpretation of Kant's relationship with skepticism in the Groundwork for the Metaphysics of Morals. My position differs from commonly held views in the literature in two ways. On the one hand, I argue that Kant's relationship with skepticism is active and systematic (contrary to Hill, Wood, Rawls, Timmermann, and Allison). On the other hand, I argue that the kind of skepticism Kant is interested in does not speak to the philosophical tradition in any straightforward sense (contrary to Forster and Guyer). On my reading, Kant takes up a skeptical method in the Groundwork as a way of exposing certain obstacles in our ordinary and philosophical thinking about morality. The central obstacle he is interested in is practical in character, arising from a natural tendency we have to rationalize against the moral law. In attempting to resolve this tendency, I argue, the Groundwork turns out to have a profoundly educative task. 相似文献

Social and general cognitive abilities decline in late life. Those with high cognitive reserve display better general cognitive performance in old age; however, it is unknown whether this is also the case for social cognition. A total of 115 healthy older adults, aged 60–85 years (m = 44, f = 71) were assessed using The Awareness of Social Inference Test (TASIT-R; social cognition), the Lifetime of Experiences Questionnaire (LEQ; cognitive reserve), and the Wechsler Abbreviated Scale of Intelligence (WASI-II; general cognitive ability). The LEQ did not predict performance on any TASIT-R subtest: Emotion Evaluation Test (β = -.097, p = .325), Social Inference – Minimal (β = -.004, p = .972), or Social Inference – Enriched (β = -.016, p = .878). Sensitivity analyses using two alternative cognitive reserve measures, years of education and the National Adult Reading Test, supported these effects. Cognitive reserve was strongly related to WASI-II performance. Unlike general cognitive ability, social cognition appears unaffected by cognitive reserve. Findings contribute to the emerging understanding that cognitive reserve differentially affects individual cognitive domains, which has implications for the theoretical understanding of cognitive reserve and its brain correlates. Cognitive measures unbiased by cognitive reserve may serve as best indicators of brain health, free of compensatory mechanisms. 相似文献

This paper describes the development and validation of an inventory to uncover youths' experiences in their neighbourhoods. The Neighbourhood Youth Inventory (NYI) was developed from conversations with youths in Grades 7, 9 and 11. This paper reports the psychometric analyses of the NYI. Responses from 934 youths (511 urban, 423 rural) to the NYI resulted in a four‐factor solution. This solution was stable across responses from youths in Grades 7, 9 and 11, and for urban and rural youths. Cronbach alphas ranged from 0.64 to 0.94. Construct, convergent and discriminant validity of the NYI subscales are demonstrated. Using the NYI we will be able to assess youths' experiences within their neighbourhoods, which may contribute to a more ecological understanding of healthy developmental outcomes beyond family, peer and school environments.
