In an early study in the Journal of Applied Behavior Analysis, Rekers and Lovaas (1974) evaluated the Behavioral Treatment of Deviant Sex-role Behaviors in a Male Child. They investigated the use of reinforcement and punishment to target non-gender-conforming behaviors of a 5-year-old male child. This study was considered by some to be controversial and concerning, even near the time of publication (Nordyke et al. 1977; Winkler, 1977). The concerns focused on the ethicality of selecting non-gender-conforming behavior as a target response and the use of punishment for this type of response, particularly at the behest of parents when the young child was not seemingly distressed. The study has subsequently been used as empirical support for conversion therapy creating concerns about misinterpretation of the original article and harm to the LGBTQ+ community. This editorial reviews the concerns originally presented by Nordyke et al. (1977) and Winkler (1977) and issues an official Expression of Concern about the various harms that have been associated with this paper. 相似文献

The current study was designed to gain a better understanding of the nature of the relationship between substance use and sexual risk taking within a community sample of women (N = 1,004). Using confirmatory factor analysis, the authors examined the factor structure of sexual risk behaviors and substance use to determine whether they are best conceptualized as domains underlying a single, higher order, risk-taking propensity. A 2 higher order factor model (sexual risk behavior and substance use) provided the best fit to the data, suggesting that these 2 general risk domains are correlated but independent factors. Sensation seeking had large general direct effects on the 2 risk domains and large indirect effects on the 4 first-order factors and the individual indicators. Negative affect had smaller, yet still significant, effects. Impulsivity and anxiety were unrelated to sexual health risk domains. 相似文献

ABSTRACT The central claim is that Hornsby's argument that semantic knowledge is practical knowledge is based upon a false premise. I argue, contra Hornsby, that speakers do not voice their thoughts directly. Rather, our actions of voicing our thoughts are justified by decisions we make (albeit rapidly) about what words to use. Along the way, I raise doubts about other aspects of the thesis that semantic knowledge is practical knowledge. 相似文献

Modal primitivists hold that some modal truths are primitively true. They thus seem to face a special epistemological problem: how can primitive modal truths be known? The epistemological objection has not been adequately developed in the literature. I undertake to develop the objection, and then to argue that the best formulation of the epistemological objection targets all realists about modality, rather than the primitivist alone. Furthermore, the moves available to reductionists in response to the objection are also available to primitivists. I conclude by suggesting that extant theories of the epistemology of modality are not sensitive to the question of primitivism versus reductionism.
