Young and old adults’ ability to recognize emotions from vocal expressions and music performances was compared. The stimuli consisted of (a) acted speech (anger, disgust, fear, happiness, and sadness; each posed with both weak and strong emotion intensity), (b) synthesized speech (anger, fear, happiness, and sadness), and (c) short melodies played on the electric guitar (anger, fear, happiness, and sadness; each played with both weak and strong emotion intensity). The listeners’ recognition of discrete emotions and emotion intensity was assessed and the recognition rates were controlled for various response biases. Results showed emotion-specific age-related differences in recognition accuracy. Old adults consistently received significantly lower recognition rates for negative, but not for positive, emotions for both speech and music stimuli. Some age-related differences were also evident in the listeners’ ratings of emotion intensity. The results show the importance of considering individual emotions in studies on age-related differences in emotion recognition.  相似文献

Affective style reflecting approach and inhibition is thought to be associated in distinct ways with anxious versus depressed mood; relatively few studies, however, consider how the interaction between affective style and the strategies individuals use to regulate mood and emotion might influence these associations. Sixty-seven non-disordered adults self-reported on their use of two emotion regulation strategies (cognitive reappraisal and expressive suppression), behavioral approach (BAS) and behavioral inhibition sensitivity (BIS) dimensions of affective style, and anxious and depressed mood (trait anxiety and symptoms of depression). Trait anxiety versus depressed mood was associated with unique interactive patterns of emotion regulation and affective style: enhanced use of reappraisal was linked to less depressed mood in those reporting low BAS, whereas high suppression was linked to greater trait anxiety in those reporting low BIS. The implications of findings for typical emotional processes and for clinical disorders and interventions are discussed.  相似文献

Hispanics have become the largest minority group in the United States. Hispanic children typically come from working class homes with parents who have limited English language skills and educational training. This presents challenges to psychologists who assess these children using traditional IQ tests because of the considerable verbal and academic (e.g., quantitative) content. Some researchers have suggested that intelligence conceptualized on the basis of psychological processes may have utility for assessment of children from culturally and linguistically diverse populations because verbal and quantitative skills are not included. This study examined Hispanic children's performance on the Cognitive Assessment System (CAS; [Naglieri, J.A., and Das, J.P. (1997). Cognitive Assessment System. Itasca, IL: Riverside.]) which is based on the Planning, Attention, Simultaneous, and Successive (PASS) theory of intelligence. The scores of Hispanic (N = 244) and White (N = 1956) children on the four PASS processes were obtained and the respective correlations between PASS and achievement compared. Three complementary sampling methodologies and data analysis strategies were chosen to compare the Ethnic groups. Sample size was maximized using nationally representative groups and demographic group differences were minimized using smaller matched samples. Small differences between Hispanic and non-Hispanic children were found when ability was measured with tests of basic PASS processes. In addition, the correlation between the PASS constructs and achievement were substantial for both Hispanic and non-Hispanic children and were not significantly different between the groups.  相似文献

The Zahlen–Verbindungs-Test (ZVT) represents a highly feasible measure of information-processing speed that correlates quite highly with standard psychometric tests of intelligence. The present study was designed to identify specific stages of the sensorimotor processing system that may account for individual differences in overall variability of ZVT performance. For this purpose, ZVT, reaction time (RT), lateralized readiness potential (LRP), and electromyogram (EMG) measures were obtained in 48 female participants. While faster RT, smaller intraindividual variability in RT, shorter response-locked LRP and EMG latencies were associated with superior ZVT performance, speed of stimulus analysis, as reflected by stimulus-locked LRP latency, was unrelated to ZVT performance. Additional commonality analyses suggested a functional relationship between ZVT performance and the time course of central aspects of response organization rather than the time required for execution of the overt motor response. These findings provide converging evidence for the general notion of an association between speed of motor processing and intelligence.  相似文献

An Information Processing Theory of Ambivalence   总被引:1,自引:0,他引:1  
This paper analyzes the sources of ambivalence toward political parties and candidates. We propose and test an information-processing theory of ambivalence in which systematic processing is hypothesized to heighten partisan and candidate ambivalence. We show that ambivalence is linked to several dispositional sources of systematic processing, including individuals' information, motivation, and cognitive style. Specifically, we find that ambivalence tends to be greater among the well informed and those who are high in need for cognition while it tends to be lower among those motivated by directional goals. Collectively, our results suggest that levels of partisan and candidate ambivalence are greatest among those most likely to engage in effortful processing of information and that these effects are independent of value conflict. The results further suggest that the effects of effortful processing on ambivalence are moderated by attitude commitment.  相似文献

认知年老化与执行衰退假说   总被引:6,自引:1,他引:5  
在认知年老化领域,执行衰退假说是近年来新兴的一种理论。执行衰退假说在理论上具有很强的吸引力,但在实证研究中却存在很多困难,如执行功能的可分离性问题,执行功能测量的信度和效度问题,以及执行功能与加工速度的关系问题。目前,该领域研究的焦点是:在行为学水平上,控制一般性因素(加工速度)后,执行功能是否仍对认知年老化起重要的中介作用;在神经水平上,执行(额叶)功能随龄的变化情况,以及在认知年老化过程中,额叶在大脑功能重组中扮演的角色。最终实现对认知年老化的理解,需要将认知功能与大脑结构联系起来;既看到广泛存在的共同的基本机制,又不能忽略不同认知结构的选择性变化。  相似文献

7~12岁儿童视觉搜索能力的发展   总被引:4,自引:0,他引:4  
该研究主要考察7~12岁儿童视觉搜索能力的发展。实验结果表明:儿童视觉搜索能力随年龄的增长而提高,性别差异不显著;儿童对三种不同视觉刺激材料(阿拉伯数字、英文字母、汉字)的视觉搜索的反应时没有表现出明显的差异,这个结果与通常的一些实验结果不同。同时,儿童在视觉搜索过程中,判断刺激出现的反应时均明显短于判断刺激没有出现的反应时;两种判断与左右手之间存在着交互作用。  相似文献

In this review, we examine the role of emotion regulation in the treatment of children with anxiety disorders. Cognitive-behavioral therapy (CBT) has been shown to “work” for children with anxiety disorders and it has been categorized as an evidence-based treatment. However, most studies have shown that the treatment is effective for about 60–70% of children, leaving the remaining children symptomatic and oftentimes with persisting psychological disorders. Of importance, it has also been shown that many children with anxiety disorders demonstrate poor emotion regulation skills. Despite these findings, little attention has been directed toward incorporating emotion regulation strategies into these relatively effective cognitive-behavioral treatments. It is possible that CBT programs do not work as well for a portion of children because their emotion regulation deficits, if present, are not being targeted sufficiently. In this review, it is suggested that adding an emotion regulation component could increase treatment efficacy. In addition, strategies aimed at improving emotion regulation at the individual level and at the family level are introduced. Details of how improved emotion regulation skills could be beneficial in bringing about change are discussed. Finally, issues of measurement and the clinical implications for research and practice are considered.  相似文献

This paper presents the architecture and functionality of a logic prover designed for question answering. The approach transforms questions and answer passages into logic representations based on syntactic, semantic and contextual information. World knowledge supplements the linguistic, ontological, and temporal axioms supplied to the prover which renders a deep understanding of the relationship between the question and answer text. The trace of the proofs provides a basis for generating human comprehensible answer justifications. The results show that the prover boosts the performance of the Question Answering system on TREC 2004 questions by 12%.  相似文献
