We report associations between serial measures of blood lead and intelligence in children age 10-12 years, half heavily exposed to lead from the prenatal period onward, and half relatively unexposed. For a subsample, we examine bone lead-IQ associations, comparing them with bone lead associations. Both blood and bone lead levels were associated with intelligence decrements, small relative to the contribution of social factors. For each doubling of Tib-Pb, Full Scale, Performance, and Verbal IQ decreased by an estimated 5.5, 6.2, and 4.1 points, respectively. Bone lead-IQ associations were stronger than those for blood lead, which nonetheless provide robust analogues. Current BPb, easy to obtain, provides a useful means for assessing Pb exposure/IQ associations. 相似文献

We consider young children's construals of biological phenomena and the forces that shape them, using Carey's (1985) category-based induction task that demonstrated anthropocentric reasoning in young urban children. Follow-up studies (including our own) have questioned the generality of her results, but they have employed quite different procedures and either have not included urban children or, when urban samples were included, have failed to reproduce her original findings. In the present study of 4–10-year-olds from three cultural communities, our procedures followed Carey's more closely and replicated her findings with young urban children. However, they yielded quite different results for young rural European American and young rural Native American children. These results underscore the importance of a complex interaction of culture and experience – including both day-to-day interactions with the natural world and sensitivity to the belief systems of the communities – in children's reasoning about the natural world. 相似文献

Although the amnestic effects of alcohol in humans are well known, its effects on emotional memory are unclear. In this study, using a randomized double-blind placebo-controlled design, we examine narrative emotional episodic memory in healthy human female volunteers (n = 32) who received either a single dose of alcohol (0.6 g/kg), or a placebo and then viewed neutral story elements presented in either a neutral or emotional context. Memory was tested for gist and detail of the neutral elements 3 days later in a surprise recognition test. Since alcohol modulates GABAergic neurotransmission and may exert its effects on emotion through the limbic system, we predicted that acute alcohol treatment would reduce the expected emotional memory-advantage for gist, leaving detail memory relatively unaffected. Furthermore, given previous findings showing that ‘primacy’ memory is enhanced by physiological arousal, we predicted that reduced arousal produced by alcohol would have the opposite effect and impair primacy memory relative to the middle or ‘recency’ sections of the narrative. Emotional arousal was expected to oppose this effect, so impaired primacy memory following alcohol was only expected in the neutral version of the narrative. Although there was a main effect of story phase (though not of story version), contrary to expectations, alcohol impaired primacy memory for emotionally encoded neutral material. The results suggest that under certain circumstances emotional context or physiological arousal make memories labile and susceptible to disruption through pharmacological manipulation during encoding. 相似文献

While conducting intervention research, researchers and practitioners are often interested in how the intervention functions
not only at the group level, but also at the individual level. One way to examine individual treatment effects is through
multiple-baseline studies analyzed with multilevel modeling. This analysis allows for the construction of confidence intervals,
which are strongly recommended in the reporting guidelines of the American Psychological Association. The purpose of this
study was to examine the accuracy of confidence intervals of individual treatment effects obtained from multilevel modeling
of multiple-baseline data. Monte Carlo methods were used to examine performance across conditions varying in the number of
participants, the number of observations per participant, and the dependency of errors. The accuracy of the confidence intervals
depended on the method used, with the greatest accuracy being obtained when multilevel modeling was coupled with the Kenward—Roger
method of estimating degrees of freedom. 相似文献

In this paper I look at attempts to develop forms of consequentialism which do not have a feature considered problematic in Direct Consequentialist theories (that is, those consequentialist theories that apply the criterion of rightness directly in the evaluation of any set of options). The problematic feature in question (which I refer to as ‘evaluative conflict’) is the possibility that, for example, a right motive might lead an agent to perform a wrong act. Theories aiming to avoid this phenomenon must argue that causal relationship entails motives and acts (for example) having the same moral status. I argue that attempts to ensure such ‘evaluative consistency’ are themselves deeply problematic, and that we must therefore accept evaluative conflict. 相似文献

Objectification theory posits that valuing one's body for appearance rather than performance is associated with a range of negative psychological outcomes. This theory has been tested in women, but has received less empirical attention in men. This study examined the relation between self-objectification and ideal body shape in both men and women. One hundred eighty-three college students (111 women, 72 men) completed a questionnaire containing measures of self-objectification and ideal body shape (using a figure array ranging from non-muscular to very muscular). Consistent with hypotheses, women desired a less muscular body and men desired a more muscular body. Women also self-objectified more than men. In addition, there was an interaction between sex and self-objectification on ideal body shape. For women, higher self-objectification scores were related to a desire for a less muscular body. For men, higher self-objectification scores were related to a desire for a more muscular body. Self-objectification theory is a useful framework for understanding body image issues in men. However, the relation between self-objectification and other body related variables may differ for men and women. 相似文献

The ‘Wrong Kind of Reason’ problem for buck-passing theories (theories which hold that the normative is explanatorily or conceptually
prior to the evaluative) is to explain why the existence of pragmatic or strategic reasons for some response to an object
does not suffice to ground evaluative claims about that object. The only workable reply seems to be to deny that there are reasons of the ‘wrong kind’ for responses, and to argue that these are really reasons for wanting, trying, or intending to
have that response. In support of this, it is pointed out that awareness of pragmatic or strategic considerations, unlike
awareness of reasons of the ‘right kind’, are never sufficient by themselves to produce the responses for which they are reasons.
I argue that this phenomenon cannot be used as a criterion for distinguishing reasons-for-a-response from reasons-for-wanting-to-have-a-response.
I subsequently investigate the possibility of basing this distinction on a claim that the responses in question (e.g. admiration
or desire) are themselves inherently normative; I conclude that this approach is also unsuccessful. Hence, the ‘direct response’
phenomenon cannot be used to rule out the possibility of pragmatic or strategic reasons for responses; and the rejection of
such reasons therefore cannot be used to circumvent the Wrong Kind of Reason Problem.

Little is known about the relationship between parent and child anxiety sensitivity (AS), particularly in nonclinical samples. The present study examined this association in 207 healthy parent-child pairs including 244 children (mean age = 12.3 years, 103 girls) and 226 parent figures (175 mothers). Sequential multiple linear regression revealed that parent AS was significantly associated with child AS in girls, but not in boys. Parent AS accounted for 9% of incremental variance in child AS, after controlling for child age, parent depression, and parent anxiety. Analyses of parent AS dimensions indicated that the social concerns dimension accounted for 14% of incremental variance in child AS in girls only. Parent anxiety and depression showed no association with child AS, once parent AS was taken into account. The findings indicate that parent AS, especially AS social concerns, demonstrates a significant relationship with child AS in this nonclinical sample of girls. 相似文献

This study examined differences between socially anxious and nonanxious individuals' ability to use effective communication skills and social skills in the context of romantic relationships. Socially anxious (n = 13) and nonanxious (n = 14) individuals and their romantic partners were videotaped while participating in 10-minute neutral, negative, and pleasant conversations. Regardless of the type of conversation in which they were involved, socially anxious individuals demonstrated impairment in 10 of the 11 social skill variables assessed. In negative conversations, socially anxious individuals displayed more "very negative" behaviors than nonanxious individuals, and across all conversations they displayed fewer "positive" behaviors than nonanxious individuals. Partners of socially anxious and nonanxious individuals did not differ in their communication quality. The results suggest that social anxiety is associated with deficits in relationship maintenance behavior and call for the completion of a larger study examining the interpersonal consequences of social anxiety. 相似文献
