A qualitative study of a supervision course included pre-and post-interviews of the participants in addition to in-class participant observation. In an effort to be consistent with a postmodern perspective, the data were reviewed by the four members of the research team, each of whom shares his or her analysis, or story. Common themes which emerged in response to the focus on student change include greater awareness of isomorphic processes, ethical and legal issues, and evaluative processes. 相似文献

Suicide is the chief cause of premature death among schizophrenic persons. The lifetime incidence of suicide for patients with schizophrenia is 10% to 13% compared to a general population estimate of about 1%, and is quite close to that observed among those with major affective disorder. The magnitude of increased risk for suicide among schizophrenics peaks before middle age and declines thereafter, although schizophrenic persons tend to be at increased risk throughout the life span. Among psychiatric patients, schizophrenics are overrepresented among suicides, and often schizophrenics constitute the majority of inpatient suicides. It is important in evaluating suicide risk among schizophrenic persons to assess depression and suicidal ideation especially during index admission and during acute phases of the illness. It is noteworthy that schizophrenic persons often commit suicide as the overall level of psychopathology decreases during a nonpsychotic phase. Research has yielded salient risk factors for suicide in schizophrenic persons and "types" of especially vulnerable patients, even though statistical prediction of individual suicides has not proven effective. 相似文献

An apnea hypothesis is proposed termed Conditioned Hyperventilation. An organism (animal, infant, or adult) can become conditioned to anticipate traumatic terminal breathing. The resulting hyperventilation produces excessive oxygen, which triggers apnea, allowing an increase in carbon dioxide. This apnea serves as an additional unconditioned stimulus (UCS) causing the hyperventilation (apnea) to increase. Organic blockage can also serve as the UCS. Apnea may be reduced or prevented by monitoring and extinguishing hyperventilation through the use of behavioral modification techniques, or biofeedback. Infant lung collapse during the first six months is suggested as one UCS in infants. 相似文献

Although there is a documented link between psychopathy and instrumental violence in adult offenders, the association between these constructs has not garnered significant attention in adolescent offenders. In this study, we evaluated the relationship between psychopathy and instrumental aggression in a sample of 122 male adolescents incarcerated in a state facility for serious and chronic offenders. We evaluated the primary (2-, 3-, and 4-factor) models of the Psychopathy Checklist: Youth Version (PCL:YV; Forth, Kosson, & Hare, 2003) and assessed their relationship to a separate 5-item measure of instrumental violence. CFA revealed good model fit for the 3- and 4-factor latent variable models of adolescent psychopathy and a single-factor model reflecting a 5-item measure of instrumental violence. Structural equation modeling results indicate that the 4-factor model accounted for 20% of the variance for instrumental violence. In contrast, the 3-factor model of the PCL:YV accounted for 8%, and the 2-factor model accounted for 5% of the variance associated with instrumental violence. 相似文献

Peer models (classmates without disabilities) who were proficient in performing a task completed one response chain each day and described the steps they performed while their classmates with disabilities observed. Three students with disabilities participated, and their performance of the response chains was assessed immediately prior to and following the peer modeling each day. A multiple probe design across response chains, replicated across children with disabilities, was used. In addition, participation and social interactions of children with disabilities and their peer models were assessed in classroom activities after daily modeling sessions. The results indicate that the peer models performed the response chains accurately and quickly, and students with disabilities acquired the response chains. Across the study, participation in classroom activities was high, social interactions were low, and neither was affected by the peer modeling intervention. 相似文献

If food pilferage has been a reliable selection pressure on food caching animals, those animals should have evolved the ability to protect their caches from pilferers. Evidence that animals protect their caches would support the argument that pilferage has been an important adaptive challenge. We observed naturally caching Eastern grey squirrels (Sciurus carolinensis) in order to determine whether they used any evasive tactics in order to deter conspecific and heterospecific pilferage. We found that grey squirrels used evasive tactics when they had a conspecific audience, but not when they had a heterospecific (corvid) audience. When other squirrels were present, grey squirrels spaced their caches farther apart and preferentially cached when oriented with their backs to other squirrels, but no such effect was found when birds were present. Our data provide the first evidence that caching mammals are sensitive to the risk of pilferage posed by an audience of conspecifics, and that they utilise evasive tactics that should help to minimise cache loss. We discuss our results in relation to recent theory of reciprocal pilferage and compare them to behaviours shown by caching birds. 相似文献

Despite the existence of effective treatment options for PTSD, these treatments are failing to reach those that stand to benefit from PTSD treatment. Understanding the processes underlying an individual's treatment seeking behavior holds the potential for reducing treatment-seeking barriers. The current study investigates the effects that positive treatment testimonials have on decisions regarding PTSD treatment. An undergraduate (N = 439) and a trauma-exposed community (N = 203) sample were provided with videotaped treatment rationales for prolonged exposure (PE) and sertraline treatments of PTSD. Half of each sample also viewed testimonials, detailing a fictional patient's treatment experience. All participants then chose among treatment options and rated the credibility of – and personal reactions toward – those options. Among treatment naïve undergraduates, testimonials increased the proportion choosing PE alone; and among treatment naïve members of the trauma-exposed community sample, testimonials increased the proportion choosing a combined PE plus sertraline treatment. These effects were not observed for those with prior history of either psychotherapeutic or pharmacological treatment. Major barriers exist that prevent individuals with PTSD from seeking treatment. For a critical unreached treatment sample, those who are treatment naïve, positive patient testimonials offer a mechanism in which to make effective treatments more appealing and accessible. 相似文献
