The behavioral immune system is designed to promote the detection and avoidance of potential sources of disease. Whereas previous studies of the behavioral immune system have provided insight into the types of heuristic cues used to identify disease carriers, the present research provides an understanding of the basic psychological processes involved in the detection of those cues. Across 4 studies, feeling vulnerable to disease, whether that feeling stemmed from dispositional tendencies or situational primes, facilitated a disease overperception bias--a tendency to overperceive people in the environment displaying heuristic disease cues. This disease overperception bias was observed in the outcomes of 2 cognitive processes: categorization and memory. When concerned about disease, participants set a lenient threshold for categorizing targets as displaying heuristic disease cues (e.g., obesity, old age). Additionally, concerns about disease led participants to set a lenient threshold for reporting on a recognition task that they had previously seen individuals displaying those disease cues. The present research provides insight into the basic cognitive mechanisms underlying the operation of the behavioral immune system. 相似文献

This study provides convergent, discriminant, and incremental validity data for a new measure of dependent personality traits from the perspective of the five-factor model (FFM). Dependent personality trait scales were constructed as maladaptive variants of FFM facets (e.g., Gullibility as a maladaptive variant of FFM trust). Based on responses from 383 undergraduates, the convergent validity of the Five-Factor Dependency Inventory (FFDI) scales was tested with respect to 2 measures of the FFM, 6 dependency trait scales, and 4 measures of dependent personality disorder. Discriminant validity was tested with respect to FFM facets from alternative domains. Incremental validity was tested with respect to the ability of the FFM dependent personality trait scales to account for variance in 2 established measures of dependency, after variance accounted for by respective FFM facet scales and other measures of DPD was first removed. The results of this study provided support for the validity of the FFDI assessment of dependency from the perspective of the FFM. 相似文献

The five-factor model (FFM) is the predominant dimensional model of general personality structure. A considerable body of research supports the hypothesis that personality disorders can be conceptualized as extreme or maladaptive variants of the domains and facets of the FFM. However, existing measures of the FFM are confined largely to the normal variants. The purpose of this special section of the Journal of Personality Assessment is to provide the development and initial validation of self-report inventory scales to assess obsessive-compulsive, borderline, narcissistic, avoidant, and dependent personality traits from the perspective of the FFM, which complement the similarly constructed existing measures for psychopathic, histrionic, and schizotypal personality traits. 相似文献

Effect of contraction intensity [100%, 75%, 50%, and 25% maximum voluntary contraction (MVC)] and movement velocity [0 degrees (isometric)], 50 degrees, 100 degrees, 200 degrees, and 400 degrees/sec. [isovelocities]) on root mean square amplitude (SEMG-RMS) and median frequency power spectrum (SEMG-MNF) of vastus lateralis (VL) surface electromyography was investigated with ten healthy female university students. Peak torque (PT), mean torque (MT), SEMG-MNF, and SEMG-RMS, analyzed using separate repeated-measures analyses of variance (p < or = .05), indicated: (1) an inverse relation between PT and MT and movement velocity, (2) greater SEMG-MNF values during all isovelocity conditions compared with isometric conditions, with highest values occurring at 50 degrees /sec. and at 100% and 75% MVC, and (3) at all contraction intensities SEMG-RMS values were higher during dynamic movements than isometric movements and highest at 200 degrees /sec. Isovelocity contractions were inferred to facilitate a greater recruitment of fast-twitch fibers (via increased SEMG-MNF), which was intensified at 50 degrees /sec., whereas greater overall muscle activation was found at 200 degrees /sec. 相似文献

Works cited in six forensic psychology journals published 2008-2010 were counted to identify the most frequently cited journals. The sample of works cited (N = 21,776) was not a definitive ranked list of important journals in forensic psychology, but was large enough to indicate high-impact journals. The list of frequently cited publications included more general psychiatry and psychology journals than titles specific to forensic psychology. The implications of the proportion of general versus specific titles for collections supporting research in forensic psychology were discussed. 相似文献

Relatively little is known about the potential interplay between genetic and environmental influences on attention-deficit/hyperactivity
disorder (ADHD), including gene-environment interaction (G×E). There is evidence that parenting behavior interacts with offspring
genotype in the development of externalizing problems, but studies have largely focused on explicit maltreatment rather than
differentiated measures of parenting behavior, including positive and negative parenting. We tested the interactive effects
of the 30-base pair variable number tandem repeat (VNTR) polymorphism of the monoamine oxidase A gene (MAO-A) with positive
and negative parenting behavior on parent- and teacher ratings of inattention and hyperactivity symptoms among 150 6–9 year-old
boys with and without ADHD. Negative parenting predicted parent and teacher ratings of inattention symptoms, but only among
boys with high-activity MAO-A genotype. MAO-A genotype did not moderate the association of positive parenting and parent-
and teacher ratings of ADHD. We discuss the potential role of interactive exchanges between parenting behavior and child genotype
in the development and persistence of ADHD and related behavior problems. 相似文献

Three conditioned suppression experiments with rats as subjects assessed the contributions of the conditioned stimulus (CS)-context and context-unconditioned stimulus (US) associations to the degraded stimulus control by the CS that is observed following partial reinforcement relative to continuous reinforcement training. In Experiment 1, posttraining associative deflation (i.e., extinction) of the training context after partial reinforcement restored responding to a level comparable to the one produced by continuous reinforcement. In Experiment 2, posttraining associative inflation of the context (achieved by administering unsignaled outcome presentations in the context) enhanced the detrimental effect of partial reinforcement. Experiment 3 found that the training context must be an effective competitor to produce the partial reinforcement acquisition deficit. When the context was down-modulated, the target regained behavioral control thereby demonstrating higher-order retrospective revaluation. The results are discussed in terms of retrospective revaluation, and are used to contrast the predictions of a performance-focused model with those of an acquisition-focused model. 相似文献

Although children born preterm or low birth weight (PT LBW) are more likely to exhibit behavior problems compared to children born at term, developmental and family processes associated with these problems are unclear. We examined trajectories of maternal depressive symptoms in relation to toddler compliance and behavior problems in families with PT LBW infants. A total of 177 infants (93 boys, 84 girls) and their mothers enrolled in the study during the infant's NICU stay. Data were collected at five time points across 2 years. Assessments of maternal depressive symptoms were conducted at all time points, and toddler compliance and opposition to maternal requests and behavior problems were assessed at 2 years. Toddlers born earlier with more health problems to mothers whose depressive symptoms increased over time exhibited the most opposition to maternal requests during a cleanup task at 24 months, consistent with multiple risk models. Mothers with elevated depression symptoms reported more behavior problems in their toddlers. The study has implications for family‐based early intervention programs seeking to identify PT LBW infants at highest risk for problem behaviors. 相似文献

Actions that do not have as their goal the advancement or protection of one's material interests are often seen as illegitimate. Four studies suggested that moral values can legitimate action in the absence of material interest. The more participants linked sociopolitical issues to moral values, the more comfortable they felt advocating on behalf of those issues and the less confused they were by others' advocacy (Studies 1 and 2). Crime victims were perceived as being more entitled to claim special privileges when the crime had violated their personal moral values (Studies 3 and 4). These effects were strongest when the legitimacy to act could not already be derived from one's material interests, suggesting that moral values and material interest can represent interchangeable justifications for behavior. No support was found for the possibility that attitude strength explained these effects. The power of moralization to disinhibit action is discussed. 相似文献

A social justice orientation for counseling is appealing to many but appears to some to violate counselor neutrality and respect for client freedom and rights. Confusion about neutrality and advocacy in the counseling field seems to reflect confused assumptions and values in the wider culture. As a result, counseling is guided more by a disguised ideology of liberal individualism than an objective theory or value‐neutral principles. The authors suggest that a hermeneutic, dialogical framework for counseling has the potential to resolve much of this confusion and to refine and broaden a social justice approach in needed ways. 相似文献
