Assessing risk of harm to self and others is an important component of psychological assessment, although methods for risk assessment vary considerably. The Personality Assessment Inventory (PAI) is frequently administered to evaluate general psychological functioning, as well as to provide information about suicide and violence risk. The purpose of this study was to evaluate the construct validity of the PAI Suicide (SPI) and Violence Potential (VPI) indices in a sample of 158 psychiatric outpatients referred for psychological and neuropsychological assessment within a large northeastern academic medical center between 2007 and 2011. Results generally supported the convergent and divergent validity of both SPI and VPI when evaluating groups with and without a history of suicide and violence risk, and effect sizes were moderate to large even after controlling for other covariates. SPI and VPI scores were also found to vary significantly across different psychiatric groups in ways that would be expected. Finally, we explored the relationship between SPI and VPI, and executive functioning impairment??a neuropsychological variable found to be associated with impulsive self and other-harming behaviors. Consistent with prior research, SPI and VPI were found to be significantly elevated in groups demonstrating executive dysfunction. The implications of these findings and specifically the utility of using SPI and VPI in the assessment of risk are discussed. 相似文献

Available research suggests that fear of negative evaluation and fear of positive evaluation are related but distinct constructs that each contribute to social anxiety, implying a need to focus on these fears in treatment. Yet, this research is almost entirely based on cross-sectional data. We examined the longitudinal relationship between fears of positive and negative evaluation over three time points in a sample of undergraduate students. We tested competing models consistent with two basic positions regarding these fears: (1) that fear of positive evaluation only appears to affect social anxiety because it arises from the same, single underlying trait as fear of negative evaluation, and (2) fears of positive and negative evaluation are correlated, but clearly distinct, constructs. The best-fitting model was an autoregressive latent-trajectory model in which each type of fear had a separate trait-like component. The correlation between these trait-like components appeared to fully account for the relationships between these constructs over time. This investigation adds to the evidence in support of the second position described above: fear of positive evaluation is best interpreted as a separate construct from fear of negative evaluation. 相似文献

Growth arrest and DNA damage-inducible β (Gadd45b) has been shown to be involved in DNA demethylation and may be important for cognitive processes. Gadd45b is abnormally expressed in subjects with autism and psychosis, two disorders associated with cognitive deficits. Furthermore, several high-throughput screens have identified Gadd45b as a candidate plasticity-related gene. However, a direct demonstration of a link between Gadd45b and memory has not been established. The current studies first determined whether expression of the Gadd45 family of genes was affected by contextual fear conditioning. Gadd45b, and to a lesser extent Gadd45g, were up-regulated in the hippocampus following contextual fear conditioning, whereas Gadd45a was not. Next, Gadd45b knockout mice were tested for contextual and cued fear conditioning. Gadd45b knockout mice exhibited a significant deficit in long-term contextual fear conditioning; however, they displayed normal levels of short-term contextual fear conditioning. No differences between Gadd45b knockout and wild-type mice were observed in cued fear conditioning. Because cued fear conditioning is hippocampus independent, while contextual fear conditioning is hippocampus dependent, the current studies suggest that Gadd45b may be important for long-term hippocampus-dependent memory storage. Therefore, Gadd45b may be a novel therapeutic target for the cognitive deficits associated with many neurodevelopmental, neurological, and psychiatric disorders. 相似文献

When interacting with others, informants may offer conflicting information or information of varying accuracy. Recent research suggests that young children do not trust all informants equally and are selective in both whom they solicit for information and whose claims they support. We explored whether domestic dogs (Canis familiaris) are similarly sensitive to agreement among informants. To this end, we utilized a common human gesture, pointing, to which recent research suggests dogs are sensitive. We conducted two experiments in which an experimenter secretly hid food in one of two clear containers while the dog was distracted. Next, a small group moved to indicate the food's location using stationary points positioned above the containers. In Experiment 1, two experimenters moved to stand behind the non-baited container, while a third experimenter moved to stand behind the baited container. Then, all directed one static point at the container in front of them. Experiment 2 exactly resembled Experiment 1 with the exception that the single experimenter standing behind the baited container directed two static points at the container (one with each hand). Dogs chose the container indicated by the majority in Experiment 1 significantly more often than chance, but chose the container indicated by the minority in Experiment 2 significantly more often than chance. This suggests that the number of points, not the number of people, more strongly influenced dogs' choices. 相似文献

This paper is about two proposals endorsed by Xunzi. The first is that there is such a thing as a moral expert, whose moral advice we should adopt even when we cannot appreciate for ourselves the considerations in favor of it. The second is that certain political authorities should be treated as moral experts. I identify three fundamental questions about moral expertise that contemporary philosophy has yet to address in depth, explicate Xunzi??s answers to them, and then give an account of politically authorized moral expertise as Xunzi understands it. The three questions at the heart of this study are these: how should we distinguish between knowing the correct course of action on another??s authority and knowing it for oneself? What exactly are the underlying considerations that the expert grasps and the novice does not? Who are the experts and in what spheres of life can they legitimately claim expertise? 相似文献

According to many theories of decision making, of which signal detection theory is the most prominent, randomness is the main factor responsible for imperfect performance. These theories imply that correcting for attenuation due to randomness should result in perfect scores as long as the participants use nonextreme decision criteria. On the basis of a recent advance termed potential performance theory (Trafimow & Rice, Psychological Review 115:447-462, 2008), we performed auditory and visual detection experiments and corrected the scores for attenuation. Most participants in both experiments tended to perform at a less-than-perfect level, even after their scores were corrected. The findings demonstrate that at least one systematic factor influences detection that is not included in signal detection theory. 相似文献

AbstractFeminist therapy altered how marriage and family therapists conceptualized their clients’ realities and psychopathology. Upon an extensive search of the literature, there is a sparse amount of literature regarding the integration of feminist therapy with experiential therapy. The authors discuss feminist and experiential therapy models, propose a model of feminist-experiential therapy, and highlight the need and fit of these theories. A discussion on giving space to silenced voices, establishing an egalitarian relationship, expanding the definition of deviance, and exploring the importance of language will be done to aid the experiential therapist in their work and expand their client’s experience. 相似文献
