This paper argues that understanding developmental disorders requires developing theories and models that explicitly represent the role of general intelligence in the cognitive phenotype of the disorder. In the case of autism it is argued that the low-IQ scores of people with autism are not likely to be due to a deficit in the cognitive process that is arguably the major cause of mental retardation - namely, speed of processing - but rather low IQ reflects the pervasive and cascading effects of the deficit in the information-processing module that causes autism. In the case of dyslexia, two radically different models of reading disorder (ability = disability and a modular deficit model) are likely to be influenced by the effect of general intelligence on reading performance in ways that will remain unclear without an explicit model of how general intelligence influences reading. 相似文献

Meta-analysis and structural equation modeling (SEM) are two important statistical methods in the behavioral, social, and medical sciences. They are generally treated as two unrelated topics in the literature. The present article proposes a model to integrate fixed-, random-, and mixed-effects meta-analyses into the SEM framework. By applying an appropriate transformation on the data, studies in a meta-analysis can be analyzed as subjects in a structural equation model. This article also highlights some practical benefits of using the SEM approach to conduct a meta-analysis. Specifically, the SEM-based meta-analysis can be used to handle missing covariates, to quantify the heterogeneity of effect sizes, and to address the heterogeneity of effect sizes with mixture models. Examples are used to illustrate the equivalence between the conventional meta-analysis and the SEM-based meta-analysis. Future directions on and issues related to the SEM-based meta-analysis are discussed. 相似文献

This article presents a response to the comment by B. J. Bushman, D. Romer, and P. E. Jamieson (2015). This reply addresses 2 issues raised by the commenters. First, they claim they and others have not made sensationalistic statements linking violent media to horrific acts of real‐world violence. In response, we supply numerous examples of sensationalistic statements made by them and others. Second, they claim they did not expect violence in films to be related to violent behavior among adults, but only among youths. However, by examining homicide arrests and homicide gun mortality rates among youths, we found that as films have become increasingly violent over time, both homicide arrests and gun‐related homicides have tended to decrease among this age group. 相似文献

Mike Males 《Suicide & life-threatening behavior》1994,24(1):24-37
From 1970 to 1990 California experienced a 32% decline in suicide, which was particularly pronounced among women, non-whites, the young, and urban dwellers. Suicide declines of over 50% were recorded in San Francisco and Los Angeles, and large decreases occurred in other coastal counties. Additionally, California was the only one of 51 states to show a consistent decline in teenage and young-adult suicide (accompanied by an 88% decrease in teenage drug and other poisoning deaths). Initial investigation of death certification, accident and homicide trends, economic measures, and prevention efforts did not produce an explanation for a suicide decrease of California's magnitude. However, the state does display anomalous trends in certain social measures (reduced divorce, rising non-White population, and rising homicide) that point to multifactorial hypotheses including demographic changes and changed attitudes toward violence. Review of the accuracy of past suicide certification procedures nationally is also indicated. 相似文献

Mike O'Leary 《Journal of Investigative Psychology & Offender Profiling》2009,6(3):253-265
We begin by describing some of the mathematical foundations of the geographic profiling problem. We then present a new mathematical framework for the geographic profiling problem based on Bayesian statistical methods that makes explicit connections between assumptions on offender behaviour and the components of the mathematical model. It also can take into account local geographic features that either influence the selection of a crime site or influence the selection of an offender's anchor point.
