Modified versions of three popular nonaversive treatments for rumination in a person with profound developmental delay were evaluated using an alternating treatments design (ATD) as a component of an ABAB design. Results showed that the most effective intervention involved noncontingent feeding every 20 s for the 30 min immediately following a meal. Further analysis demonstrated that no significant increase in rumination occurred during the 60 min after the treatment procedure had expired, thus indicating that rumination was not merely postponed. Results are discussed in terms of their relation to currently popular (satiation) interventions for the treatment of rumination in individuals with developmental disability. Future research needs are proposed from an analysis of known behavioral and physiological variables and their possible interactions. ©1997 by John Wiley & Sons, Ltd. 相似文献

Processing language requires the retrieval of concepts from memory in response to an ongoing stream of information. This retrieval is facilitated if one can infer the gist of a sentence, conversation, or document and use that gist to predict related concepts and disambiguate words. This article analyzes the abstract computational problem underlying the extraction and use of gist, formulating this problem as a rational statistical inference. This leads to a novel approach to semantic representation in which word meanings are represented in terms of a set of probabilistic topics. The topic model performs well in predicting word association and the effects of semantic association and ambiguity on a variety of language-processing and memory tasks. It also provides a foundation for developing more richly structured statistical models of language, as the generative process assumed in the topic model can easily be extended to incorporate other kinds of semantic and syntactic structure. 相似文献

Virtually all human individual differences have been shown to be moderately heritable. Much of this research, however, focuses on measures of dysfunctional behavior and relatively fewer studies have focused on positive traits. The values in action (VIA) project is a comprehensive and ambitious classification of 24 positive traits, also known as character strengths (Peterson, C., & Seligman, M. E. P. (2004). Character strengths and virtues: A handbook and classification. Washington, DC: American Psychological Association), the majority of which have received no behavior genetic attention. Using a sample of 336 middle-aged twins drawn from the Minnesota Twin Registry who completed the VIA inventory of strengths, we detected significant genetic and non-shared environmental effects for 21 of 24 character strengths with little evidence of shared environmental contributions. Associations with a previously administered measure of normal personality found moderate phenotypic overlap and that genetic influences on personality traits could account for most, but not all, of the heritable variance in character strengths. 相似文献

The authors offer an integral approach to counseling ethics using K. Wilber's (2000a, 2000b) integral metatheory. The article examines traditional counseling ethics through the lens of K. Wilber's (2000a, 2000b) “all‐quadrants, all‐levels” model, consisting of quadrants, levels, lines, states, and types. The authors begin with the 4 quadrants and how they can inform understanding of traditional counseling ethics. Vertical development in relation to counseling ethics is addressed, followed by a case study of an ethical dilemma in counseling. The authors offer an integrally informed process of ethical decision making that can be seen to complement less comprehensive ethical decision‐making models. 相似文献

This study examined the association of borderline personality disorder (BPD) and negative emotional states with impulsivity in the laboratory. Undergraduate participants who were high in BPD features (high-BPD; n = 39) and controls who were low in BPD features (low-BPD; n = 56) completed measures of negative emotional state before a laboratory measure of impulsivity--a passive avoidance learning task. Controlling for psychopathology, high-BPD participants committed a greater number of impulsive responses than did low-BPD participants. Negative emotional state moderated the effect of BPD on impulsive responses. High-BPD participants who were in a negative emotional state committed fewer impulsive responses than high-BPD participants who were low in negative emotional state. Fear, nervousness, and shame negatively correlated with impulsivity among high-BPD participants but not among low-BPD participants. In addition, high-BPD participants reported greater emotion dysregulation in a variety of domains, compared with low-BPD participants. 相似文献

Why are people trustworthy? I argue for two theses. First, we cannot explain many socially important forms of trustworthiness solely in terms of the instrumentally rational seeking of one’s interests, in response to external sanctions or rewards. A richer psychology is required. So, second, possession of moral character is a plausible explanation of some socially important instances when people are trustworthy. I defend this conclusion against the influential account of trust as ‘encapsulated interest’, given by Russell Hardin, on which most trustworthiness is explained by the interest of continuing relationship. 相似文献

Although research has indicated that cognitions and situational factors play a role in relationship satisfaction and aggression, few studies have investigated the association between intimate partner violence (IPV) and relationship values. We addressed this gap by measuring college students’ perpetration of and victimization by four types of IPV; namely, physical violence, sexual violence, threats, and psychological aggression over the past year. One-way ANOVAs and multiple regression analyses were used to measure the association between IPV and the endorsement of relationship values. The results suggest that past IPV perpetration and victimization correlated with the current endorsement of relationship values for males more than females. In general, male perpetrators rated relationship values such as security, investment, others’ approval, and daily conflict as less important than non-perpetrators. Although male victimization explained significant variance in security, investment, and others’ approval, the results were somewhat mixed as to whether victimization related to higher or lower ratings of relationship values, with the majority of the results suggesting an inverse correlation between relationship value endorsement and IPV experience. Future research can investigate mediating factors in the relationship between IPV and relationship value endorsement, as well as look at how IPV and relationship values influence decisions concerning relationship maintenance. 相似文献
