People often shop when feeling sad, but whether and why shopping reduces residual (lingering) sadness remains an open question. Sadness is strongly associated with a sense that situational forces control the outcomes in one's life, and thus we theorized that the choices inherent in shopping may restore personal control over one's environment and reduce residual sadness. Three experiments provided support for our hypothesis. Making shopping choices helped to alleviate sadness whether they were hypothetical (Experiment 1) or real (Experiment 2). In addition, all experiments found support for the underlying mechanism of personal control restoration. Notably, the benefits of restored personal control over one's environment do not generalize to anger (Experiments 2 and 3), because anger is associated with a sense that other people (rather than situational forces) are likely to cause negative outcomes, and these appraisals are not ameliorated by restoring personal control over one's environment. 相似文献

In four experiments we explored whether participants would be able to use probabilistic prompts to simplify perceptually demanding visual search in a task we call the retrieval guidance paradigm. On each trial a memory prompt appeared prior to (and during) the search task and the diagnosticity of the prompt(s) was manipulated to provide complete, partial, or non-diagnostic information regarding the target's color on each trial (Experiments 1–3). In Experiment 1 we found that the more diagnostic prompts was associated with faster visual search performance. However, similar visual search behavior was observed in Experiment 2 when the diagnosticity of the prompts was eliminated, suggesting that participants in Experiment 1 were merely relying on base rate information to guide search and were not utilizing the prompts. In Experiment 3 participants were informed of the relationship between the prompts and the color of the target and this was associated with faster search performance relative to Experiment 1, suggesting that the participants were using the prompts to guide search. Additionally, in Experiment 3 a knowledge test was implemented and performance in this task was associated with qualitative differences in search behavior such that participants that were able to name the color(s) most associated with the prompts were faster to find the target than participants who were unable to do so. However, in Experiments 1–3 diagnosticity of the memory prompt was manipulated via base rate information, making it possible that participants were merely relying on base rate information to inform search in Experiment 3. In Experiment 4 we manipulated diagnosticity of the prompts without manipulating base rate information and found a similar pattern of results as Experiment 3. Together, the results emphasize the importance of base rate and diagnosticity information in visual search behavior. In the General discussion section we explore how a recent computational model of hypothesis generation (HyGene; Thomas, Dougherty, Sprenger, & Harbison, 2008), linking attention with long-term and working memory, accounts for the present results and provides a useful framework of cued recall visual search. 相似文献

Six experiments used a within-subjects renewal design to examine the involvement of kappa opioid receptors (KORs) in regulating the expression and recovery of extinguished fear. Rats were trained to fear a tone conditioned stimulus (CS) via pairings with foot shock in a distinctive context (A). This was followed by extinction training of the CS in a second context (B). Finally, all rats were tested for fear to the tone in the extinction context (ABB) and the training (ABA) or a novel (ABC) context. Intracerebroventricular (ICV) infusion of the KOR antagonist nor-binaltorphimine dihydrochloride (nor-BNI) dose-dependently prevented ABA renewal of fear, but had no effect on the expression of ABC renewal, the expression of extinction, or the expression of nonextinguished fear. Conversely, pretest infusion of the KOR agonist U50,488 hydrochloride (U50,488) selectively facilitated the expression of ABA renewal and had no effect on the expression of extinction. Pretest infusion of nor-BNI had no effect on the expression of context-specific latent inhibition. Collectively, these results suggest that KORs gate the expression of fear following extinction training and may comprise a critical neuropeptide component of the circuitry underlying context-dependent expression of fear. 相似文献

The influence of stable individual differences on behaviour need not solely rely upon deliberative processes but can also be exerted through automatic associative processes. In this contribution, three studies that illustrate the role of individual differences in automaticity are presented in the domain of helping behaviour. The first study provides evidence both for a double dissociation and for an additive pattern of implicit and explicit measures in predicting relevant altruistic behaviours. The subsequent two studies show that when the concept of altruism is subliminally primed, individual differences in implicit attitudes significantly predict behaviour. The results are in line with the gatekeeper model, and their implications are discussed focusing on the key role of individual differences in modulating automaticity effects.

This study used latent class analysis (LCA) to empirically derive profiles of religious involvement among a sample of 808
young adults and describe ethnic and gender differences within such religious involvement patterns. Items on the Duke Religion
Index (DRI) were included as part of a larger longitudinal survey of emotional, physical, and behavioral health. The scale
measured the organizational, nonorganizational, and intrinsic dimensions of religiosity (Koenig et al. in Handbook of religion
and health, Oxford University Press, Oxford, 2001) in a sample of young adults at two waves of the study—age 27 and age 30. At age 27, five religious profiles were distinguishable
in the sample while at age 30 six profiles emerged. Ethnic differences were found for each of the religious profiles where
religious involvement manifested in different ways. Religious profiles between ages 27 and 30 changed over time and were affected
by gender and ethnicity. 相似文献

Individual differences in affect intensity are typically assessed with the Affect Intensity Measure (AIM). Previous factor analyses suggest that the AIM is comprised of four weakly correlated factors: Positive Affectivity, Negative Reactivity, Negative Intensity and Positive Intensity or Serenity. However, little data exist to show whether its four factors relate to other measures differently enough to preclude use of the total scale score. The present study replicated the four-factor solution and found that subscales derived from the four factors correlated differently with criterion variables that assess personality domains, affective dispositions, and cognitive patterns that are associated with emotional reactions. The results show that use of the total AIM score can obscure relationships between specific features of affect intensity and other variables and suggest that researchers should examine the individual AIM subscales. 相似文献

Adolescence is a period of heightened susceptibility to anxiety disorders, yet we have little experimental evidence on what factors may lead to psychopathology in adolescence. Preclinical models of extinction are commonly used to study the treatment of anxiety symptoms. Interestingly, recent research has shown that there are fundamental changes in the process of extinction across development, which may have implications for our understanding of psychopathology across the lifespan. Specifically, this research shows that the process of extinction parallels the nonlinear function of prefrontal cortex development, such that extinction behaviour is similar in juvenile and adult rats, but involves different processes in infancy and adolescence (periods of rapid growth and pruning, respectively). Our previous studies have shown that early-life stress accelerates the transition between infant and juvenile extinction systems. In the current series of experiments, we examined whether the same early-life stress, maternal separation (MS), would lead to an earlier transition between the juvenile and adolescent extinction systems, and between the adolescent and adult extinction systems. We show that MS adolescent rats exhibit more adult-like extinction behaviour, and that adolescent-like extinction emerges earlier in development (i.e. in pre-adolescent rats). These results may have important implications for the understanding and treatment of anxiety symptoms in adolescent populations. 相似文献

Reading comprehension plays an important role in achievement for all academic domains. The purpose of this study is to describe the sentence verification technique (SVT) (Royer, Hastings, &; Hook, 1979) as an alternative method of assessing reading comprehension, which can be used with a variety of texts and across diverse populations and educational contexts. Additionally, this study adds a unique contribution to the extant literature on the SVT through an investigation of the precision of the instrument across proficiency levels. Data were gathered from a sample of 464 fourth-grade students from the Northeast region of the United States. Reliability was estimated using one, two, three, and four passage test forms. Two or three passages provided sufficient reliability. The conditional reliability analyses revealed that the SVT test scores were reliable for readers with average to below average proficiency, but did not provide reliable information for students who were very poor or strong readers. 相似文献
