This article analyzes the effortful control of automatic processing related to social and emotional behavior, including control over evolved modules designed to solve problems of survival and reproduction that were recurrent over evolutionary time. The inputs to effortful control mechanisms include a wide range of nonrecurrent information--information resulting not from evolutionary regularities but from explicit appraisals of costs and benefits. Effortful control mechanisms are associated with the ventromedial prefrontal cortex and the ventral anterior cingulated cortex. These mechanisms are largely separate from mechanisms of cognitive control (termed executive function) and working memory, and they enable effortful control of behavior in the service of long range goals. Individual differences in effortful control are associated with measures of conscientiousness in the Five Factor Model of personality. Research in the areas of aggression, ethnocentrism, sexuality, reward seeking, and emotion regulation is reviewed indicating effortful control of automatic, implicit processing based on explicit appraisals of the context. Evidence is reviewed indicating that evolutionary pressure for cooperation may be a critical adaptive function accounting for the evolution of explicit processing. 相似文献

In the standard numerical anchoring paradigm, the influence of externally provided anchors on judgment is typically explained as a result of elaborate thinking (i.e., confirmatory hypothesis testing that selectively activates anchor-consistent information in memory). In contrast, theories of attitude change suggest that the same judgments can result from relatively thoughtful or non-thoughtful processes, with more thoughtful processes resulting in judgments that last longer over time and better resist future attempts at change. Guided by an attitudinal approach to anchoring, four studies manipulated participants’ level of cognitive load to produce relatively high versus low levels of thinking. These studies show that, although anchoring can occur under both high and low thought conditions, anchoring based on a higher level of thinking involves greater use of judgment-relevant background knowledge, persists longer over time, is more resistant to subsequent attempts at social influence, and is less likely to result from direct numeric priming. 相似文献

In four experiments, we examined the effect of pairing colors with either homogeneous or heterogeneous shapes on a short-term memory task. In Experiment 1, we found no differences in color memory for displays in which colors were each associated with different shapes, paired with individual homogeneous shapes, or paired with heterogeneous shapes. In contrast, in Experiment 2, we found that when participants were asked to remember the specific pairings of colors, memory was improved for heterogeneous-shape displays. The benefit for heterogeneous shapes appears to be memorial, rather than one that occurs at the time of encoding (Experiment 3) or retrieval (Experiment 4). The present study suggests that distinctive shapes can be used to help bind color associations in visual short-term memory. 相似文献

Three experiments investigated the ability to perceive the maximum height to which another actor could jump to reach an object. Experiment 1 determined the accuracy of estimates for another actor's maximal reach-with-jump height and compared these estimates to estimates of the actor's standing maximal reaching height and to estimates of the perceiver's own maximal reaching and reach-with-jump height. Perception of another actor's maximum reach-with-jump height was less accurate than the other estimates, but still accurate to within 8% error. The actor's reach-with-jump height was modified in Experiment 2 by attaching weights around the actor's ankles. Perceivers, who were explicitly aware of the manipulation, adjusted their maximum reach-with-jump estimates for the actor accordingly. In Experiment 3, perceivers were not explicitly aware of the weight manipulation, but provided significantly lower maximum reach-with-jump estimates after watching the actor walk while wearing the weights compared to estimates obtained after watching the actor walk while not wearing the weights. The results suggest that the actor's walking pattern was informative about the actor's capacity to produce a different action, jumping to reach an object. 相似文献

A prospective analysis of acceptance of pain and values-based action in patients with chronic pain. 总被引:1,自引:0,他引:1
OBJECTIVE: Acceptance of pain and values-based action appear important in the emotional, physical, and social functioning of individuals with chronic pain. The purpose of the current study was to prospectively investigate these combined processes. METHOD: 115 patients attending an assessment and treatment course for chronic pain in the U.K. completed a standard set of measures on two occasions separated by an average of 18.5 weeks. RESULTS: Correlation analyses showed that acceptance of pain and values-based action measured at Time 1 were significantly correlated with pain, pain-related distress, pain-related anxiety and avoidance, depression, depression-related interference with functioning, and physical and psychosocial disability measured at Time 2. Multiple regression analyses, in which pain and relevant patient background variables were controlled, showed that the combined acceptance and values measures accounted for between 6.5% and 27.0% of variance in six key measures of patient functioning later in time. CONCLUSION: These results support the importance of acceptance and values-related processes in relation to chronic pain. These results also encourage continued applications of a functional contextual model of psychopathology, the model underlying Acceptance and Commitment Therapy and related approaches such as Contextual Cognitive-Behavioral Therapy. 相似文献

In 2 experiments, the authors explored age of acquisition (AoA) and word frequency (WF) effects in picture naming using the psychological refractory period paradigm. In Experiment 1, participants named a picture and then, a short time later, categorized 1 of 3 possible auditory tones as high, medium, or low. Both AoA (Experiment 1A) and WF (Experiment 1B) effects propagated onto tone discrimination reaction times (RTs), with the effects of AoA being stronger. In Experiment 2, the to-be-named picture followed the auditory tone by a varying interval. As the interval decreased, picture naming RTs increased. The relationship between the interval and AoA (Experiment 2A) was reliably underadditive; AoA effects were eliminated at the shortest interval. In contrast, WF (Experiment 2B) was additive with the effects of the interval. These results demonstrate an empirical dissociation between AoA and WF effects. AoA affects processing stages that precede those that are sensitive to WF. The implications for theories of picture naming are discussed. 相似文献

To investigate how the culturalist perspective on investigating racial group differences in standardized cognitive ability tests has advanced, a content analysis of 28 studies citing J. E. Helms (1992) identified 7 general themes. Overall, researchers cited J. E. Helms (1992) as support for their own hypotheses but did not directly test the culturalist perspective. Para investigar cómo ha avanzado la perspectiva culturalista sobre la investigación de las diferencias entre grupos raciales en los tests estandarizados de abilidades cognitivas, un análisis de contenido de 28 estudios que citan a J. E. Helms (1992) identificó 7 temas generales. En conjunto, los investigadores citaron a J. E. Helms (1992) para apoyar sus propias hipótesis, pero no comprobaron la perspectiva culturalista directamente. 相似文献

Conventional wisdom in much of the educational and psychological literatures states that the ethnic and racial identity of
African American students is related to their academic achievement. The purpose of this study was to determine whether ethnic
identity and anti-white attitudes predicted the academic achievement of African American students at a historically Black
university. A hypothesized path model was proposed that included ethnic identity, attitudes toward other ethnic groups, anti-white
attitudes, perceptions of caring faculty, academic self-concept, and devaluing academic success. The path analysis model explained
27% of the variance in grade point average and revealed three direct effects on grade point average: (a) academic self-concept
(positive), (b) devaluing academic success (negative), and (c) anti-white attitudes (negative). Ethnic identity was indirectly
linked with grade point average (GPA) through academic self-concept and devaluing academic success. Tests of two alternative
nested models suggest that even in an indirect role, ethnic identity may be more important than anti-white attitudes in a
model of African American academic achievement.

A number of studies have evaluated counselling interventions for people with myalgic encephalitis, but few report client perceptions in any detail. This study seeks to explore client perceptions using a qualitative methodology. A sample of 25 individuals with myalgic encephalitis were interviewed about their experiences in counselling. The interviews were transcribed and subjected to thematic analysis using grounded theory principles. The analysis showed that people with myalgic encephalitis endure significant changes to their lives, often involving great loss and trauma. After seeking help through counselling, participants had experienced a wide variety of approaches and there were positive and negative perceptions of each. Other perceptions related to therapist characteristics and the way in which interventions were carried out. Recommendations for practitioners are given. 相似文献
