ABSTRACT— Mammals, including humans, show sex differences in juvenile play behavior. In rodents and nonhuman primates, these behavioral sex differences result, in part, from sex differences in androgens during early development. Girls exposed to high levels of androgen prenatally, because of the genetic disorder congenital adrenal hyperplasia, show increased male-typical play, suggesting similar hormonal influences on human development, at least in females. Here, we report that fetal testosterone measured from amniotic fluid relates positively to male-typical scores on a standardized questionnaire measure of sex-typical play in both boys and girls. These results show, for the first time, a link between fetal testosterone and the development of sex-typical play in children from the general population, and are the first data linking high levels of prenatal testosterone to increased male-typical play behavior in boys. 相似文献

In immediate serial recall short words are better recalled than long words. The word length effect has become pivotal in the development of short-term memory models. The current research tests one explanation of the word length effect; that it is related to proactive interference (PI). We report two experiments in which the relationship is directly tested. In the first experiment we show that word length effects can be observed over the first few trials in an experiment and that the effect shows itself primarily in the number of omissions made. In the second experiment we simultaneously test for PI and word length effects. Strong word length effects were present but there was little evidence for PI influencing either overall levels of recall or the word length effect. In short, no empirical support was found for PI as an explanation of the word length effect. 相似文献

Previous research has shown the performance of the CJDATS Co-Occurring Disorders Screening Instruments (CODSI-MD and SMD)--six- and three-item instruments to screen for any mental disorder (CODSI-MD) and for severe mental disorders (CODSI-SMD), respectively--to be comparable or superior to other, longer instruments. This study tested the stability of the performance of the CODSI-MD and SMD across three racial/ethnic groups of offenders entering prison substance abuse treatment programs (n = 353), consisting of 96 African American, 120 Latino, and 137 White admissions. The Structured Clinical Interview (SCID) was used to obtain DSM-IV Axis I and II diagnoses; a lifetime SCID diagnosis of a mental disorder or a severe mental disorder was the criterion against which the CODSI-MD and SMD were validated. Results showed no statistical differences in sensitivity or specificity for either the CODSI-MD or SMD across the African American, Latino, and White prisoner groups. The value of the CODSI-MD and SMD as brief screens for mental disorders among offenders with diverse racial/ethnic backgrounds is discussed. 相似文献

Against a backdrop of increasing concern about the adequacy of treatment for co-occurring substance use and mental disorders (typically known as "co-occurring disorders," or COD) in the criminal justice system, this article attempts to provide empirical evidence for a typology of levels of COD treatment for offenders in both prison and community settings. The paper investigates two levels of treatment programs for COD; "intermediate" programs, in which treatment programming has been designed primarily for offenders with a single disorder, and "advanced" programs, in which programming has been designed to provide integrated substance abuse treatment and mental health services. Findings from a national survey of program directors indicated that both intermediate and advanced COD treatment programs were similar in their general approach to substance abuse treatment, but differed considerably in their treatment of mental disorders, where the advanced programs employed significantly more evidence- and consensus-based practices. Results provide support for the distinction between intermediate- and advanced-level services for offenders with COD and support a typology that defines advanced programs as integrating a range of evidence- and consensus-based practices so as to modify treatment sufficiently to address both diseases. 相似文献

In this paper, we introduce a new approach to creativity assessment. Arguably, one of the main obstacles to creativity assessment is that creativity criteria are likely to change depending on what is assessed and who is making the assessment. We argue that we might be able to solve this problem by adopting a relational ontology, i.e., an ontology according to which beings of the world acquire their properties by relating to other beings. First, we present the main consequences of this ontological approach for creativity assessment: (a) Accounting for the creativity of a given object involves retracing the beings (including criteria) that relate it to its alleged creativity; (b) One can assess the creativity of this object by looking at the number of beings that substantiate this relation, i.e., by looking at what we call the “degree of solidity” of the relation; (c) One can thus account for the specificity of various forms of creativity and, at the same time, compare them in terms of solidity. Building on these ontological assumptions, we then present a new assessment technique, the Objection Counting Technique, before putting it to the test using an excerpt taken from a naturally occurring brainstorming session. 相似文献
