The authors assessed whether (a) early illicit drug use predicted later risky sexual activity, (b) early risky sex predicted later illicit drug use, and (c) common factors affected both risky sexual behavior and illicit drug use. African American and Puerto Rican youth completed questionnaires in their classrooms at Time 1 (T1) and face-to-face interviews with the authors in their homes 5 years later at Time 2 (T2). Logistic regression analyses showed the association between T1 illicit drug use and T2 risky sexual activity and between T1 risky sexual behavior and T2 illicit drug use. With few exceptions, T1 illicit drug use was associated with all of the T2 risky sexual behaviors. After controlling for demographic factors, the authors found that multiple sex partners at T1 was not related to illicit drug use at T2. Condom use at T1 was related to illicit drug use at T2, whereas sexually transmitted diseases and adolescent pregnancy were not related to this drug use. The findings indicated that assessments of and treatments for substance use should focus on the risky sexual behaviors that seem to accompany illicit drug use. 相似文献

The authors examined a cross-sectional interrelationship of psychosocial domains as they relate to aggression in a group of African American and English-speaking Puerto Rican children living in New York City. The population included 80 biological children of African American and Puerto Rican young adults who had been participating in the authors' ongoing longitudinal study, and 77 mothers or mother substitutes (rearing mothers) of those children. The authors performed hierarchical multiple regression analysis. The results indicated that (a) the child's personality and maternal attributes were significantly related to the child's aggression, despite control on all of the other domains and (b) the ethnic identification and discrimination domain was no longer related to the child's aggression with control on the mother-child relationship domain or on the child's personality domain. The findings have implications for clinical practice and public policy. 相似文献

We examine whether children's performance on a false-belief task is impaired by task content that activates an early-developing, prepotent motivational system: predator-avoidance. In two studies (N = 46 and N = 37), children aged 3-4 years completed variants of a false-belief task that involved predator-avoidance, playmate-avoidance, prey-seeking, and playmate-seeking, respectively. The proportion of correct answers on the playmate-avoidance task (Study 1: 52%; Study 2: 51%) was significantly greater than the proportion of correct answers on the analogous predator-avoidance task (Study 1: 28%; Study 2: 22%). This difference was not an artifact of children generally performing better on playmate stories than on predator-prey stories. The findings are consistent with the hypothesis that activation of the predator-avoidance system generates prepotent response patterns that pre-empt full consideration of the mental states of the prey characters in false-belief stories. 相似文献

Conduct Disorder in Girls: A Review of the Literature 总被引:8,自引:0,他引:8
The study of Conduct Disorder (CD) has primarily been limited to boys. The lack of research resulted from a premise that CD in girls was rare. However, CD in girls is a relatively common psychiatric diagnosis, and appears to be associated with several serious outcomes, such as Antisocial Personality Disorder and early pregnancy. Understanding gender differences in the course and severity of CD may lead to important information about etiology. Empirical studies on precursors, developmental course, risk factors and treatment for CD in girls are reviewed, while highlighting similarities and differences between girls and boys. Generally, CD symptoms in girls are stable. Precursors to CD in girls probably include Oppositional Defiant Disorder and temperamental factors, but also may include certain negative cognitions. What distinguishes CD in girls is the high risk they have to develop comorbid conditions, especially internalizing disorders. Risk factors for CD in girls partly overlap with those known for boys, but some factors appear to be highly salient for girls. Finally, there may be some significant effects of gender on treatment efficacy. Implications of these findings for future etiologic research are discussed. 相似文献

A smile may communicate different communicative intentions depending on subtle characteristics of the facial expression. In this article, we propose an algorithm to determine the morphological and dynamic characteristics of virtual agent's smiles of amusement, politeness, and embarrassment. The algorithm has been defined based on a virtual agent's smiles corpus constructed by users and analyzed with a decision tree classification technique. An evaluation, in different contexts, of the resulting smiles has enabled us to validate the proposed algorithm. 相似文献

The Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5) workgroup for disruptive behavior disorders is considering adopting a frequency threshold for symptoms of oppositional defiant disorder (ODD). In the present study, the impact of substituting the term "often" with a specific age-based frequency on impairment and prognosis among preschool children was tested in a longitudinal design. Mutually exclusive groups were created to identify children who met criteria for ODD based on a symptom threshold of "often," as in Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition (DSM-4), and those that met criteria for ODD based on a threshold of "1-2 times per day," which approximated the proposal for DSM-5. Comparisons of these groups to each other and to nondiagnosed peers determined the impact of changing the symptom threshold on impairment and prognosis. Close to one-third of children who met DSM-4 criteria for ODD did not meet criteria under the alternative diagnosis; African American children were overrepresented in this group. Preschoolers who met DSM-4, but not the alternative criteria, had higher rates of ODD, conduct disorder (CD), and were more impaired than their nondiagnosed peers at baseline and follow-up. Preschoolers meeting DSM-4 criteria were less impaired than children meeting the alternative ODD criteria at baseline according to parent, but not according to teacher report. No differences could be detected between those meeting DSM-4 and those meeting the alternative criteria in rate of ODD, CD, or impairment at follow-up. Among clinically referred preschool children, changing the symptom threshold for ODD could result in a sizable group of children who would no longer meet diagnostic criteria, despite demonstrating significant morbidity concurrently and prospectively. 相似文献

How does the remarkable human ability for face recognition arise over development? Competing theories have proposed either late maturity (beyond 10 years) or early maturity (before 5 years), but have not distinguished between perceptual and memory aspects of face recognition. Here, we demonstrate a perception–memory dissociation. We compare rate of development for (adult, human) faces versus other social stimuli (bodies), other discrete objects (cars), and other categories processed in discrete brain regions (scenes, bodies), from 5 years to adulthood. For perceptual discrimination, performance improved with age at the same rate for faces and all other categories, indicating no domain‐specific development. In contrast, face memory increased more strongly than non‐face memory, indicating domain‐specific development. The results imply that each theory is partly true: the late maturity theory holds for face memory, and the early maturity theory for face perception. 相似文献

Longitudinal mixture models have become popular in the literature. However, modest attention has been paid to whether these models provide a better fit to the data than growth models. Here, we compared longitudinal mixture models to growth models in the context of changes in depression and anxiety symptoms in a community sample of girls from age 10 to 17. Model comparisons found that the preferred solution was a 5-class parallel process growth mixture model that differed in the course of depression and anxiety symptoms reflecting both ordering of symptoms and qualitative group differences. Comparisons between classes revealed substantive differences on a number of outcomes using this solution. Findings are discussed in the context of clinical assessment and implementation of growth mixture models. 相似文献

A 6‐year‐old boy with autism spectrum disorder engaged in automatically maintained stereotypy in the form of opening and closing doors. A functional analysis confirmed that he also emitted problem behavior that was maintained by access to stereotypy. We evaluated the separate and combined effects of functional communication training and arbitrary noncontingent reinforcement on both response classes. Results showed that the combination of functional communication training and noncontingent reinforcement was more effective at reducing stereotypy than either intervention on its own, although effects on problem behavior were unclear. These results suggest that combinations of interventions may be useful in the treatment of automatically maintained problem behavior. 相似文献
