Studies of amniotic testosterone in humans suggest that fetal testosterone (fT) is related to specific (but not all) sexually dimorphic aspects of cognition and behaviour. It has also been suggested that autism may be an extreme manifestation of some male‐typical traits, both in terms of cognition and neuroanatomy. In this paper, we examine the possibility of a link between autistic traits and fT levels measured in amniotic fluid during routine amniocentesis. Two instruments measuring number of autistic traits (the Childhood Autism Spectrum Test (CAST) and the Child Autism Spectrum Quotient (AQ‐Child)) were completed by these women about their children (N=235), ages 6–10 years. Intelligence Quotient (IQ) was measured in a subset of these children (N=74). fT levels were positively associated with higher scores on the CAST and AQ‐Child. This relationship was seen within sex as well as when the sexes were combined, suggesting this is an effect of fT rather than of sex per se. No relationships were found between overall IQ and the predictor variables, or between IQ and CAST or AQ‐Child. These findings are consistent with the hypothesis that prenatal androgen exposure is related to children exhibiting more autistic traits. These results need to be followed up in a much larger sample to test if clinical cases of ASC have elevated fT. 相似文献

There is an ongoing debate regarding the diagnostic overlap between Attention Deficit Hyperactivity Disorder (ADHD) and Fetal Alcohol Spectrum Disorder (FASD). Differential diagnosis is important because of treatment implications. Children aged 7–10 years (47 ADHD, 30 FASD, 39 controls) participated. The Movement Assessment Battery for Children (M-ABC) and the Clinical Observations of Motor and Postural Skills (COMPS) were used. Force plate and electromyography data were collected during static balance and balance perturbation. On the M-ABC both children with ADHD and FASD had more motor problems than controls. The ADHD-Combined and the ADHD-Predominantly Inattentive subgroups were similarly affected in their fine motor skills. On the COMPS, the majority of children in both groups performed in the normal range, but for those children clinically affected, it was the children with ADHD who were more likely to be severely impaired. The children with ADHD were characterized by early onset latencies of the tibialis anterior muscles and increased amplitudes of the gastrocnemius muscles. Difficulty scaling muscle force reflecting medial cerebellar involvement may be the key problem in ADHD. Cerebellar involvement in the postural instability in FASD awaits further study. 相似文献

People often remember what they attend to in the world. Such memory can be cast as a kind of mental catalog or index of attended objects. To investigate how such an index is acquired and used, protocol data were collected from a programmer who scrolled to off-screen objects from time to time as she worked. These protocol data were modeled using Soar, which constrains how the index is constructed. In the model, an index entry is an episodic trace encoded during attention. The trace associates the attention event with a time symbol denoting the event's occurrence. Later, the model can ask itself whether it saw that object by calling to mind an image of the attention event. If this image retrieves a time symbol, then the model infers that the object exists and can reason about bringing the object back into view. Episodic indexing is a theory of these encoding and retrieval processes. It posits that information about attention events is encoded automatically, but that retrieval requires effort and knowledge. Episodic indexing is congruent with a range of results on episodic and temporal codes and recognition and recall processes. It incorporates source monitoring (Johnson, Hashtroudi, & Lindsay, 1993) and is a simple and pervasive form of long-term working memory (Ericsson & Kintsch, 1995). 相似文献

The purpose of this article is to characterize and evaluate the phases through which feminist positions on the family have evolved in recent history and to suggest feminists in Christian and Jewish theology and religious studies as among the most important participants in current discussions about the family. 相似文献

The authors employed a structured interview to ascertain public defenders' perceptions of their clients' competence and the degree of their participation in the defense. In a sample of 122 randomly selected, non-dismissed felony cases, attorneys had doubts about the competence of 14.8% (n = 18) of their clients. Attorneys reported that clients whose competence was doubted were less involved in decision-making and, overall, were passive participants in their cases. Nearly one-half of these clients were not referred for assessment by a mental health professional. The authors compare the practices of attorneys faced with clients of suspected competence with those of mental health clinicians treating patients with impairments in decision-making capacity. 相似文献

It was hypothesized that the greater influence of external cues on obese than on normal individuals' eating behavior is a manifestation of a generalized sensitivity to external cues. Responsivity of nut consumption to the external cue of shells on the nuts and responsivity of judgment of verticality to the external cue of a tilted visual field were assessed for male and female, obese and normal-weight subjects. As predicted, both obese subjects' nut consumption and their judgments of verticality were more influenced by external cues than were those of normals. Females' judgments of verticality were more influenced by external cues than males' were, but the sex differences in eating behavior were not statistically significant. A significant correlation between the field dependence of subjects' eating behavior and their judgments of verticality suggests that a single cause may generate sensitivity to external cues in these two diverse situations. 相似文献
