In three visual search experiments participants were asked to make a target response if either of two targets was present and to make a nontarget response if neither target was present. Some target-absent displays included only nontarget features that never occurred in the same displays as target features, whereas other target-absent displays included nontarget features that did sometimes occur with target features. Nontarget responses were reliably faster in the former case than in the latter. This “associated nontargets effect” appears to arise from participants' ability to learn and to use contingencies between the presence of certain nontargets and the absence of any target. 相似文献

The current study examined the relation between self-esteem and the Big Five personality dimensions. Data were collected over the Internet from a large heterogeneous sample of individuals who ranged in age from 9 to 90 years (N = 326,641). Collectively, the Big Five accounted for 34% of the variance in self-esteem. High self-esteem individuals were emotionally stable, extraverted, and conscientious and were somewhat agreeable and open to experience. Despite an extensive search for potential mediators and moderators of this general pattern, the relations between self-esteem and the Big Five largely cut across age, sex, social class, ethnicity, and nationality (United States vs non-United States). High self-esteem individuals tended to ascribe socially desirable traits to themselves, and this tendency partially mediated relations between the Big Five and self-esteem. Discussion focuses on interpreting the social desirability effects, limitations of the study, and directions for future research. 相似文献

The ability to differentiate anxiety and depression has been a topic of discussion in the adult and youth literatures for several decades. The tripartite model of anxiety and depression proposed by L. A. Clark and D. Watson (1991) has helped focus the discussion. In the tripartite model, anxiety is characterized by elevated levels of physiological hyperarousal (PH), depression is characterized by low levels of positive affect (PA), and negative affect (NA) or generalized emotional distress is common to both. The advent of the model led to the development of measures of tripartite constructs and subsequent validity studies. The tripartite model and resultant activity concerning the model was largely devoted to adult samples. However, those interested in anxiety and depression among youth are now incorporating the tripartite model in their work. This paper examines the current influence of the tripartite model in the youth literature, especially with regard to measuring anxiety and depression. 相似文献

Understanding the Vital Human Quest for Self-Esteem 总被引:1,自引:0,他引:1

ABSTRACT— Authors have long noted the human penchant for self-esteem. Experimental research has revealed that this desire for self-esteem has wide-ranging effects on cognition, emotion, and behavior. Terror management theory explains that this desire for self-esteem results from a fundamental need for psychological security, which is engendered by humans' awareness of their own vulnerability and mortality. A large body of evidence has supported this explanation. Specifically, substantial lines of research have shown that self-esteem buffers anxiety and reduces defenses against death and that reminders of mortality increase efforts to defend and bolster self-esteem. Complementary findings have helped clarify the role of culture in self-esteem striving and the ways in which people can vary in their level, stability, and sources of self-esteem. I conclude by briefly considering how this contemporary knowledge regarding the quest for self-esteem informs current events and daily life. 相似文献

Basic research into the prevalence, natural course, and phenomena of comorbidity of depressive disorders during childhood are reviewed and implications of this research for treating depressed youths are noted. Results of investigations into the biological aspects of depression are integrated into a multifactorial model of depressive disorders during childhood and the efficacy of pharmacological interventions is discussed. Cognitive theory is integrated with attachment theory to explain a possible avenue to the development of depressive disorders during childhood. Interpersonal therapy has emerged as a potentially effective intervention for depressed youths. Basic tenets of this treatment model are compared and contrasted to a cognitive-behavioral treatment model, and a hybrid treatment referred to as “cognitive therapy within the interpersonal context” is proposed. 相似文献

The precision of an eye-tracker is critical to the correct identification of eye movements and their properties. To measure a system’s precision, artificial eyes (AEs) are often used, to exclude eye movements influencing the measurements. A possible issue, however, is that it is virtually impossible to construct AEs with sufficient complexity to fully represent the human eye. To examine the consequences of this limitation, we tested currently used AEs from three manufacturers of eye-trackers and compared them to a more complex model, using 12 commercial eye-trackers. Because precision can be measured in various ways, we compared different metrics in the spatial domain and analyzed the power-spectral densities in the frequency domain. To assess how precision measurements compare in artificial and human eyes, we also measured precision using human recordings on the same eye-trackers. Our results show that the modified eye model presented can cope with all eye-trackers tested and acts as a promising candidate for further development of a set of AEs with varying pupil size and pupil–iris contrast. The spectral analysis of both the AE and human data revealed that human eye data have different frequencies that likely reflect the physiological characteristics of human eye movements. We also report the effects of sample selection methods for precision calculations. This study is part of the EMRA/COGAIN Eye Data Quality Standardization Project. 相似文献

This study investigated social attention impairments in autism (social orienting, joint attention, and attention to another's distress) and their relations to language ability. Three- to four-year-old children with autism spectrum disorder (ASD; n = 72), 3- to 4-year-old developmentally delayed children (n = 34), and 12- to 46-month-old typically developing children (n = 39), matched on mental age, were compared on measures of social orienting, joint attention, and attention to another's distress. Children with autism performed significantly worse than the comparison groups in all of these domains. Combined impairments in joint attention and social orienting were found to best distinguish young children with ASD from those without ASD. Structural equation modeling indicated that joint attention was the best predictor of concurrent language ability. Social orienting and attention to distress were indirectly related to language through their relations with joint attention. These results help to clarify the nature of social attention impairments in autism, offer clues to developmental mechanisms, and suggest targets for early intervention. 相似文献

Recent studies of redundancy gain indicate that it is especially large when redundant stimuli are presented to different hemispheres of an individual without a functioning corpus callosum. This suggests the hypothesis that responses to redundant stimuli are speeded partly because both hemispheres are involved in the activation of the response. A simple formal model incorporating this idea is developed and then elaborated to account for additional related findings. Predictions of the latter model are in good qualitative agreement with data from a number of sources, and there is neuroanatomic and psychophysiological support for its underlying structure. 相似文献

The present research investigated the hypotheses that elderly people can be reminders of our mortality and that concerns about our own mortality can therefore instigate ageism. In Study 1, college-age participants who saw photos of two elderly people subsequently showed more death accessibility than participants who saw photos of only younger people. In Study 2, making mortality salient for participants increased distancing from the average elderly person and decreased perceptions that the average elderly person possesses favorable attitudes. Mortality salience did not affect ratings of teenagers. In Study 3, these mortality salience effects were moderated by prior reported similarity to elderly people. Distancing from, and derogation of, elderly people after mortality salience occurred only in participants who, weeks before the study, rated their personalities as relatively similar to the average elderly person's. Discussion addresses distinguishing ageism from other forms of prejudice, as well as possibilities for reducing ageism. 相似文献
