Using ideas from evolution, and what is known about higher stages of development, we examine a hypothetical scenario, in which new humanoid species, called Superions, are produced. What would then happen with current humans? Recent genetic engineering advances have led to creating life forms with particular characteristics. Scientists are already genetically engineering human beings. Some changes are to improve health. Engineering of traits such as intelligence, higher stage reasoning or less neuroticism is also very likely. This is seen as the ultimate terrorist act because it is genocide, not against a culture, but against an entire species. The article will also discuss how Homo Sapiens could defend themselves against this. Relating two species (systems), the Homo Sapiens and Superions constitutes metasystematic operations. Developing a system of discourse that would not destroy the Homo-sapiens requires paradigmatic operations (Sonnert and Commons, Individ Soc 4:31–35, 1994). 相似文献

Ethical guidelines require school psychologists to ensure that their assessment practices are nondiscriminatory, but typical discussions on this topic neglect the possible discriminatory effects of cultural stereotypes on assessment results. Recent research on stereotype threat shows that students' knowledge of stereotype-based negative expectations about their test performance can depress their actual test performance. This paper discusses the range of conditions that promote stereotype threat and identifies important moderators and mediators of the phenomenon. Several practical suggestions are offered for school psychologists to consider when interviewing students, interpreting assessment results, and developing programs to increase schoolwide achievement. 相似文献

In this article, the authors have 2 aims. First, hierarchical, nonhierarchical, and nonstandard log-linear models are defined. Second, application scenarios are presented for nonhierarchical and nonstandard models, with illustrations of where these scenarios can occur. Parameters can be interpreted in regard to their formal meaning and in regard to their magnitude. The interpretation of the meaning of parameters is the main focus of this article. Design matrices are used to describe the hypotheses tested in models and to illustrate cases in which parameters are interpretable. Also, design matrices are used to show where and how nonstandard models differ from standard hierarchical models. Coding schemes are discussed, in particular, dummy coding and effects coding. Data examples are given with data and models discussed in the literature. 相似文献

Anxiety disorders are common, costly and debilitating, and yet often unrecognized or inadequately treated in real world, primary care settings. Our group has been researching ways of delivering evidence-based treatment for anxiety in primary care settings, with special interest to preserving the fidelity of the treatment while at the same time promoting its sustainability once the research is over. In this paper, we describe the programs we have developed and our directions for future research. Our first study evaluated the efficacy of CBT and expert pharmacotherapy recommendations for panic disorder in primary care, using a collaborative care model of service delivery (CCAP). Symptom, disability and mental health functioning measures were superior for the intervention group compared to treatment as usual both in the short term and the long term, although also more costly. In our ongoing CALM study, we have extended our population to include panic disorder, social anxiety disorder, generalized anxiety disorder and posttraumatic disorder, while at the same time utilizing clinicians with limited mental health care experience. In addition to pharmacotherapy management, we developed a computer-assisted CBT that guides both novice clinician and patient, thereby contributing to sustainability once the research is over. We have also incorporated a measurement based approach to treatment planning, using a web-based tracking system of patient status. To date, the computer-assisted CBT program has been shown to be acceptable to clinicians and patients. Clinicians rated the program highly, and patients engaged in the program. Future directions for our research include dissemination and implementation of the CALM program, testing potential alternations to the CALM program, and distance delivery of CALM. 相似文献

This research examines children’s beliefs about moral behavior in the virtual world and the real world. Participants were 515 children, average age 12 years old. One-third were African American and two-thirds were Caucasian American. Children completed surveys mailed to their homes which included questions about the acceptability of morally questionable virtual behaviors. Findings indicated: (1) gender and race differences in the acceptability of morally questionable behaviors in the virtual world; (2) moral behavior and moral attitudes in the real world predicted the acceptability of morally questionable behaviors in the virtual world; and (3) the frequency of IT use predicted the acceptability of morally questionable behaviors in the virtual world. Implications for children’s IT education are discussed. 相似文献

The standard practice of reducing every same-different data set to two numbers (hits and false alarms) is wasteful, because the response pattern to all four stimulus pairs carries information about the decision rule adopted by the observer. We describe eight rules organized in three families: differencing, covert classification, and likelihood ratio. We prove that each family produces a characteristic pattern of (in)equalities among the response probabilities. We propose two simple qualitative tests. Is the performance on stimulus pairs AA and BB statistically indistinguishable? If not, differencing and likelihood-ratio strategies can be rejected. Is the performance on pairs AB and BA indistinguishable? If not, covert classification can be rejected. We present algorithms for fitting two covert-classification models and illustrate the new methodology in a perceptual learning experiment on visual motion-direction discrimination. The standard assumption of symmetric decision criteria was violated. 相似文献

Die Posttraumatische Belastungsst?rung (PTBS, engl.: posttraumatic stress disorder, PTSD) wird klinisch charakterisiert durch
die Symptomtrias „Wiedererinnern“ (so genannte intrusive Symptomatik, engl.: re-experiencing), „Vermeidung und Bet?ubung“
(engl.: avoidance and numbing) und „vegetative übererregbarkeit“ (engl.: increased arousal). Diese St?rung stellt insofern
eine Ausnahme des ph?nomenologisch-beschreibenden, diagnostischen Ansatzes der modernen psychiatrischen Diagnosesysteme dar,
als sie einen eindeutigen ?tiologischen Bezug nimmt – n?mlich auf ein erlebtes Trauma. Im Folgenden sollen spezielle Aspekte
der PTBS zur geschichtlichen Entwicklung der Erfassung des St?rungsbildes sowie betreffend Diagnose, Risiko-und Resilienzfaktoren,
Neurobiologie und Therapie dargestellt werden. 相似文献

Two experiments using event-related potentials (ERPs) examined the extent to which early traumatic experiences affect children's ability to regulate voluntary and involuntary attention to threat. The authors presented physically abused and nonabused comparison children with conflicting auditory and visual emotion cues, posed by children's mothers or a stranger, to examine the effect of emotion, modality, and poser familiarity on attention regulation. Relative to controls, abused children overattended to task-relevant visual and auditory anger cues. They also attended more to task-irrelevant auditory anger cues. Furthermore, the degree of attention allocated to threat statistically mediated the relationship between physical abuse and child-reported anxiety. These findings indicate that extreme emotional experiences may promote vulnerability for anxiety by influencing the development of attention regulation abilities. 相似文献
