ABSTRACTSeveral studies have established the impact of conceptually similar context on the emergence of “Context-Effect” (CE). None of these studies included the Re-pair/rearrange condition at the test, which prevented them from being conclusive about the exact process (binding/ensemble or familiarity) that was affected by the conceptually similar context. To this end, in the present study faces (target to be remembered) were presented in the context of either words (W) or picture (P) scenes, and at test Re-pair was added as one of the context conditions. At test two groups were presented with the same context as in study (consistent condition) (WW & PP), and two groups with the inconsistent condition (WP & PW). Results showed no familiarity effect when only the conceptual match was preserved (i.e., inconsistent condition) and both effects of binding and familiarity when both conceptual and perceptual match were present (i.e., consistent condition). Thus, the semantic association between a face and context could serve as recognition cues even when modality has been changed, but the label remained constant. 相似文献

The current study investigates two recently identified threats to the construct validity of behavioral inhibition as a core
deficit of attention-deficit/hyperactivity disorder (ADHD) based on the stop-signal task: calculation of mean reaction time
from go-trials presented adjacent to intermittent stop-trials, and non-reporting of the stop-signal delay metric. Children
with ADHD (n = 12) and typically developing (TD) children (n = 11) were administered the standard stop-signal task and three variant stop-signal conditions. These included a no-tone
condition administered without the presentation of an auditory tone; an ignore-tone condition that presented a neutral (i.e.,
not associated with stopping) auditory tone; and a second ignore-tone condition that presented a neutral auditory tone after
the tone had been previously paired with stopping. Children with ADHD exhibited significantly slower and more variable reaction
times to go-stimuli, and slower stop-signal reaction times relative to TD controls. Stop-signal delay was not significantly
different between groups, and both groups’ go-trial reaction times slowed following meaningful tones. Collectively, these
findings corroborate recent meta-analyses and indicate that previous findings of stop-signal performance deficits in ADHD
reflect slower and more variable responding to visually presented stimuli and concurrent processing of a second stimulus,
rather than deficits of motor behavioral inhibition. 相似文献

In Uganda, one in five children presents mental health challenges, including disruptive behavior disorders (DBDs). DBDs can persist through adulthood and result in negative outcomes. Effective interventions for DBDs have been developed and tested in high-poverty communities in developed countries. Yet, most African countries, such as Uganda, lack such interventions. This paper describes the adaptation process of an evidence-based intervention of U.S. origin to optimize fit to context with intervention fidelity, as part of a randomized trial conducted with youth that exhibit behavioral challenges and their caregivers in 30 schools in Uganda. The process involved: initial meetings with headteachers and teachers to introduce the study and the main concepts of the intervention; initial manual review focusing on 4Rs and 2Ss content by the Uganda team; engagement of community stakeholders for additional feedback on content and cultural relevance; final revision of the manual; and collection of children’s drawings for the illustration of the manual. This paper describes both similarities and differences between the original and adapted intervention content and methods of delivery. The findings also highlight the importance of involving community stakeholders in the adaptation process. 相似文献

We studied economic choice behavior in capuchin monkeys by offering them to choose between two different foods available in variable amounts. When monkeys selected between familiar foods, their choice patterns were well-described in terms of relative value of the two foods. A leading view in economics and biology is that such behavior results from stimulus-response associations acquired through experience. According to this view, values are not psychologically real; they can only be defined a posteriori. One prediction of this associative model is that animals faced for the first time with a new pair of foods learn to choose between them gradually. We tested this prediction. Surprisingly, we find that monkeys choose as effectively between new pairs of foods as they choose between familiar pairs of foods. We therefore, propose a cognitive model in which economic choice results from a two-stage mental process of value-assignment and decision-making. In a follow-up experiment, we find that the relative value assigned to three foods in sessions in which we tested them against each other combine according to transitivity. 相似文献

The contention that basic behavioral intentions are forecasted by emotional expressions has received surprisingly little empirical
support. We introduce a behavioral task that gauges the speed with which movement of angry and fearful faces (toward or away
from an expressor's gaze) are accurately detected. In two studies we found that perceivers were faster to correctly detect
approaching anger faces (i.e., faces that moved in the direction of their own gaze). The opposite, however, was not true for
fear expressions. These findings offer evidence that, at least for anger displays, the basic behavioral intent to approach
is strongly transmitted and at very low-levels of processing, even priming congruent behavioral responses in observers. The
null results for fear faces may indicate that these signal a “freezing” response or behavioral inhibition rather than flight
per se. The results of this work are discussed in relation to contemporary theories of emotion. 相似文献

Cognitive-behavioral therapy for insomnia (CBTi) has demonstrated considerable efficacy within randomized clinical trials and case-series designs. This case-series study in a community sleep medicine clinic assessed the effectiveness of an eight-session CBTi protocol chronic insomnia patients who were allowed to continue their use of hypnotics (intent-to-treat n = 48), administered by a clinical psychology doctoral student receiving training and supervision in CBTi by a behavioral sleep medicine certified clinician. Outcome measures included daily sleep diaries, self-report measures on insomnia severity, dysfunctional beliefs and attitudes about sleep, daytime sleepiness, as well as medication usage. Patients showed significant improvements in sleep onset latency, wake time after sleep onset, sleep efficiency, insomnia severity, and dysfunctional sleep beliefs from pre- to post-treatment. No changes were seen in daytime sleepiness - patients were not excessively sleepy either before or after treatment. Use of sleep medication declined significantly from 87.5% pre-treatment to 54% post-treatment, despite no active efforts to encourage patients to withdraw. Results demonstrate that a CBTi conducted in a community sleep medicine clinic with patients not required to discontinue sleep-related medications can have similar effects as therapy delivered among those not on medication. 相似文献

Thought suppression research in the area of social phobia provides conflicting evidence regarding whether individuals demonstrate a general deficit or successful suppression. This paper reports the outcome of two studies using an online thought suppression paradigm measuring activation of target thoughts. Study 1 examined the effects of suppressing social threat stimuli with a healthy control group. Surprisingly, the results showed that participants demonstrated non-suppression of this stimuli class. Study 2 compared individuals with social phobia to a control group using the same stimuli as Study 1. Results revealed that following instructions to suppress social threat stimuli, individuals with social phobia demonstrated successful suppression, whilst the control group, as in Study 1, did not. The lack of suppression of social threat information by the control group may reflect functional impression-management of social threat stimuli. Whereas, successful suppression of these stimuli by individuals with social phobia, may contribute to diminished habituation to such information. 相似文献

Transference occurs when a perceiver's representation of a significant other is activated and applied to a new target person (Andersen & Chen, 2002). Extending past research, it was hypothesized that transference occurs even when a target person possesses a core feature—namely, group membership status—that is inapplicable to the relevant significant-other representation. Supporting this, transference led perceivers to make representation-consistent memory and evaluation judgments about a target—regardless of whether the target's political (experiment 1) or ethnic (experiment 2) group membership was the same or different from that of the relevant significant other. Moreover, in experiment 2, perceivers undergoing transference involving a positively evaluated significant other behaved more positively toward the target even when the target was from an ethnic out-group. The results represent initial evidence of transference processes occurring across group boundaries. Implications for transference and the reduction of out-group bias are discussed. 相似文献

Around the world, members of racial/ethnic minority groups typically experience poorer health than members of racial/ethnic majority groups. The core premise of this chapter is that thoughts, feelings, and behaviours related to race and ethnicity play a critical role in healthcare disparities. Social psychological theories of the origins and consequences of these thoughts, feelings, and behaviours offer critical insights into the processes responsible for these disparities and suggest interventions to address them. We present a multilevel model that explains how societal, intrapersonal, and interpersonal factors can influence ethnic/racial health disparities. We focus our literature review, including our own research, and conceptual analysis at the intrapersonal (the race-related thoughts and feelings of minority patients and non-minority physicians) and interpersonal levels (intergroup processes that affect medical interactions between minority patients and non-minority physicians). At both levels of analysis, we use theories of social categorisation, social identity, contemporary forms of racial bias, stereotype activation, stigma, and other social psychological processes to identify and understand potential causes and processes of health and healthcare disparities. In the final section, we identify theory-based interventions that might reduce ethnic/racial disparities in health and healthcare. 相似文献

The purpose of this study was to ascertain whether there is a differential relationship in the socialization of children with respect to gender identification when responses of children were examined with respect to race and sex (N = 596 fifth and sixth grade boys and girls). Strong father preference was found to have no effect on the choice a boy will make when choosing between male and female peers, during preadolescence, while a strong mother preference by a girl is related to the sex of the peers she chooses. Preadolescent girls who identify with their mothers chose girls with whom to interact in a variety of activities more frequently than they chose boys. A greater proportion of girls preferred to engage in activities with their mothers than boys preferred to engage in activities with their fathers. No differences were observed between racial groups in terms of girls' choices involving peers. Black boys, however, preferred to engage in activities with opposite-sex rather than same-sex peers to a greater extent than white boys. 相似文献
