MEGA? is a comprehensive, ecologically framed, structured risk assessment tool for assessing sexually abusive behavior, coarse sexual improprieties, or both in all youth under 19 years, including male and female adjudicated and nonadjudicated youth, children under 12, and youth with low intellectual functioning. MEGA?, or Multiplex Empirically Guided Inventory of Ecological Aggregates for Assessing Sexually Abusive Adolescents and Children (Ages 19 and Under; Miccio-Fonseca, 2006b) is composed of 7 aggregates and 4 distinct risk scales: (a) Risk Scale, (b) Protective Risk Scale, (c) Estrangement Risk Scale, and (d) Persistent Sexual Deviancy Scale. Discussed are the internal consistency findings on a sample of 1,184 (979 males and 205 females). MEGA?'s Risk and Protective Risk Scales are discussed in depth. 相似文献

归类任务中负启动效应与分心物特性抑制的实验研究 总被引:4,自引:1,他引:3
以汉语单字词为材料,采用负启动技术,在归类任务中考察了作为负启动效应根源的扩散抑制是否遵循资源有限机制以及在要求操作反应的情况下是否也能获得来自分心物特性抑制的负启动效应。结果表明:1.被试对曾在启动显示中作为分心物的探测目标的反应时随着启动显示中分心物数目的增加而缩短。因此,扩散抑制遵循资源有限机制;2.在操作反应要求下能获得非常显著的来自分心物特性抑制的负启动效应。 相似文献

Three adolescent students with special educational needs were given a choice between completing one of two available sets of math problems. Reinforcers (nickels) across these alternatives were arranged systematically in separate experimental phases according to three different concurrent variable-interval schedules (reinforcement ratios of 2:1, 6:1, and 12:1). Time allocated to the two stacks of math problems stood in linear relationship to the reinforcement rate obtained from each stack, although substantial undermatching and bias were observed for all subjects. However, changes in the schedules were not followed by changes in allocation patterns until adjunct procedures (e.g., changeover delays, limited holds, timers, and demonstrations) were introduced. The necessity of adjunct procedures in establishing matching in applied situations is discussed as a limitation to quantitative applications of the matching law in applied behavior analysis. 相似文献

Despite interest in exercise as a treatment for anxiety disorders the mechanism behind the anxiolytic effects of exercise is unclear. Two observations motivate the present work. First, engagement of attention control during increased working memory (WM) load can decrease anxiety. Second, exercise can improve attention control. Therefore, exercise could boost the anxiolytic effects of increased WM load via its strengthening of attention control. Anxiety was induced by threat of shock and was quantified with anxiety-potentiated startle (APS). Thirty-five healthy volunteers (19 male, age M?=?26.11, SD ?=?5.52) participated in two types of activity, exercise (biking at 60–70% of heart rate reserve) and control-activity (biking at 10–20% of heart rate reserve). After each activity, participants completed a WM task (n-back) at low- and high-load during safe and threat. Results were not consistent with the hypothesis: exercise vs. control-activity increased APS in high-load (p?=?.03). However, this increased APS was not accompanied with threat-induced impairment in WM performance (p?=?.37). Facilitation of both task-relevant stimulus processing and task-irrelevant threat processing, concurrent with prevention of threat interference on cognition, suggests that exercise increases cognitive ability. Future studies should explore how exercise affects the interplay of cognition and anxiety in patients with anxiety disorders. 相似文献

If and Then: A Critique of Speculative NanoEthics 总被引:7,自引:4,他引:3
Alfred Nordmann 《Nanoethics》2007,1(1):31-46
Most known technology serves to ingeniously adapt the world to the physical and mental limitations of human beings. Humankind
has acquired awesome power with its rather limited means. Nanotechnological capabilities further this power. On some accounts,
however, nanotechnological research will contribute to a rather different kind of technological development, namely one that
changes human beings so as to remove or reduce their physical and mental limitations. The prospect of this technological development
has inspired a fair amount of ethical debate. Here, proponents and opponents of such visions of human enhancement are criticized
alike for engaging in speculative ethics. This critique exposes a general pattern that extends to other nano-, bio-, or neuroethical
debates. While it does not apply to all discussions of “enhancement technologies” it does apply to all ethical discourse that
constructs and validates an incredible future which it only then proceeds to endorse or critique. This discourse violates
conditions of intelligibility, squanders the scarce and valuable resource of ethical concern, and misleads by casting remote
possibilities or philosophical thought-experiments as foresight about likely technical developments. In effect, it deflects
consideration from the transformative technologies of the present.

本文力图把康德的公民伦理思想置于其历史理性的理论框架之中来思考其限度及趋向。在康德历史理性的言说中,公民在康德那里作为“有限的理性存在者”,它是自我作为有限存在者“并非无拘”。康德对于用“有限理性存在者”来对其公民伦理思想进行限定,一方面基于康德公民伦理思想是道德形而上学的实践理性理论,另一方面出于他对卢梭的法权哲学原则的呼应。从价值趋向、交往结构、制度规范、内在德性、权利属性、外在环境等方面对康德的公民伦理思想展开分析,可以察知康德公民伦理思想的趋向也体现为世界公民状态。 相似文献

Limited prosocial emotions (LPE) are characterized by a lack of remorse or guilt, callousness/lack of empathy, being unconcerned about performance, and shallow/deficient affect. While previous research has largely focused on the presence or absence of LPE in youth, there is considerable evidence that symptom presence/absence and symptom impairment are separable dimensions, where impairment often is found to play a significant, unique role in assessing child psychopathology. The current study utilized a newly developed questionnaire with the purpose of exploring its psychometric properties and better understand the dual and potentially differential role LPE symptom presence and LPE-related impairment have in youth. Mothers (n = 265) of children (Mage = 8.04, SD = 2.07) completed questionnaires assessing LPE impairment, LPE symptoms, externalizing disorder symptoms, and functional impairment. Results demonstrated strong support for the psychometric properties of the newly developed measure of LPE impairment. Importantly, LPE-related impairment uniquely predicted all impairment domains above-and-beyond the effects of LPE symptoms, oppositional defiant disorder, and CD symptoms (as well as child age and sex covariates). Moreover, youth in the top 25th percentile on both LPE symptoms and LPE-related impairment (compared to youth only in the top 25th percentile in LPE symptoms) had greater mean externalizing symptoms and functional impairment. The preliminary evidence provided suggests researchers and clinicians may benefit from assessing both LPE symptoms and LPE-related impairment when attempting to identify youth with high levels of conduct problem symptoms and/or psychosocial impairment. Future research should aim to replicate and expand our findings to other clinical populations. 相似文献
