The role of perspective taking in affective decision making was studied in children at two ages (3 and 4 years) using a delay-of-gratification paradigm in which children chose between an immediate reward of lower value and a delayed reward of higher value. Half the children chose for themselves (self condition), and half chose for the experimenter (other condition). Three-year-olds chose delayed rewards in the other condition but made impulsive choices in the self condition. Compared with 3-year-olds, 4-year-olds performed better in the self condition and worse in the other condition. Results suggest that 3-year-olds took either a subjective, first-person perspective (for self) or an objective, third-person perspective (for other). Four-year-olds integrated these perspectives, considering a third-person perspective in the self condition and the experimenter's subjective perspective in the other condition (i.e., her desire for immediate gratification). This integration allowed reason to be tempered by emotion, and vice versa.  相似文献

Executive function is recognized as a critical component of children's cognitive and social development. In two studies, a measure of executive function that had been used in research with chimpanzees was adapted for preschoolers. On this task, called Less Is More, children must point to a smaller reward (two candies) to receive a larger reward (five candies). In Study 1 (N= 101), performance was significantly related to age (3 vs. 4), verbal ability, and established measures of executive function. In Study 2 (N= 128), symbolic representations substituted for real candies in this task. Three-year-olds' performance improved significantly as a function of symbolic distancing. This research has implications for the role of symbol systems in the development of executive control over thought and action.  相似文献

We present our findings on the current well-being of 125 adolescent girls living in families receiving Temporary Assistance for Needy Families Program (TANF) in terms of their health, mental health, and substance abuse status, academic performance, and teenage behaviors. This mixed-method study included separate structured face-to-face interviews with each adolescent and her mother. In addition, 20 daughters were randomly selected and completed more in-depth qualitative interviews. The findings suggest that generally the daughters were in good physical health although they reported mental health problems at about twice the rate that would be expected in a general pediatric sample. Further, about 3–5% of the daughters had a potential serious substance abuse problem. With respect to school, about 28% were not currently attending school although the majority of daughters who were attending school maintained a B average or better. Nearly two-thirds of the daughters reported being sexually active and almost 17% of the adolescents had children of their own, much higher than the 2.9% national rate of girls in this age cohort. While many of these daughters life circumstances may not be optimal, findings from both the quantitative and qualitative interviews with both mothers and daughters indicate that these daughters possess many strengths, abilities, and desires.  相似文献

The purpose of this study was to determine whether 2 forms of attentional inhibition, inhibition of return (IOR) and inhibitory tagging, are differentially affected by the aging process. The authors tested 24 younger adults (mean age = 22 years) and 24 older adults (mean age = 69 years) on a combined IOR and Stroop task (Vivas & Fuentes, 2001). As predicted, younger adults' performance was consistent with inhibitory tagging of objects at inhibited locations. Although older adults demonstrated intact IOR, there was no evidence of inhibitory tagging. The results suggest that age deficits in inhibition are selective.  相似文献

Computer-based studies usually produce log files as raw data. These data cannot be analyzed adequately with conventional statistical software. The Chemnitz LogAnalyzer provides tools for quick and comfortable visualization and analyses of hypertext navigation behavior by individual users and for aggregated data. In addition, it supports analogous analyses of questionnaire data and reanalysis with respect to several predefined orders of nodes of the same hypertext. As an illustration of how to use the Chemnitz LogAnalyzer, we give an account of one study on learning with hypertext. Participants either searched for specific details or read a hypertext document to familiarize themselves with its content. The tool helped identify navigation strategies affected by these two processing goals and provided comparisons, for example, of processing times and visited sites. Altogether, the Chemnitz LogAnalyzer fills the gap between log files as raw data of Web-based studies and conventional statistical software.  相似文献

Healthy people generally underestimate the self-reported well-being of people with disabilities and serious illnesses. The cause of this discrepancy is in dispute, and the present study provides evidence for 2 causes. First, healthy people fail to anticipate hedonic adaptation to poor health. Using an ecological momentary assessment measure of mood, the authors failed to find evidence that hemodialysis patients are less happy than healthy nonpatients are, suggesting that they have largely, if not completely, adapted to their condition. In a forecasting task, healthy people failed to anticipate this adaptation. Second, although controls understated their own mood in both an estimation task and a recall task, patients were quite accurate in both tasks. This relative negativity in controls' estimates of their own moods could also contribute to their underestimation of the moods and overall well-being of patients.  相似文献

We show that online processing difficulties induced by word order variations in German cannot be attributed to the relative infrequency of the constructions in question, but rather appear to reflect the application of grammatical principles during parsing. Event-related brain potentials revealed that dative-marked objects in the initial position of an embedded sentence do not elicit a neurophysiologically distinct response from subjects, whereas accusative-marked objects do. These differences are predictable on the basis of grammatical distinctions (i.e. underlying linguistic properties), but not on the basis of frequency information (i.e. a superficial linguistic property). We therefore conclude that the former, but not the latter, guides syntactic integration during online parsing.  相似文献

After reviewing the different psychoanalytical approaches to language of authors such as Freud, Lacan, Kristeva, Jung and Nicolas Abraham, the author examines the problem of 'analytical listening', of the attitude that every analyst must assume towards the words of the analysand, words that must be heard not just in terms of their content but above all in terms of their sound. We live in a culture in which visual images predominate over acoustic images and all too often this cultural trend is repeated in analysis, but it is only when we can hear the 'poetry' of the analysand's discourse that we are able to provide an 'echo', an analytical response that can co-symbolize with, that can offer to the analysand a word or a metaphor that will unlock the symbol hidden behind his or her words. The author then turns to the problem of bilinguism and its role in analysis. In her view, bilingual analysts are facilitated in their task of listening and of translation, because bilinguism facilitates the rapidity and fluidity of the analyst's associations, and at the same time sharpens his or her awareness of how the sound of a word can subtly change its meaning. The paper ends with a clinical vignette which illustrates the role that language can play in hysteria. In hysteria the dissociation between body and psyche is accompanied by a dissociation inside language itself, between verbalization and vocalization. These dissociations can be linked to the traumatic impact of the encounter between the 'language of tenderness' and the 'language of passion', between the child's attachment needs and parental sexuality. In such cases the failure of communication can be resolved principally through the use the analyst makes of the countertransference.  相似文献

Optimizing well-being: the empirical encounter of two traditions   总被引:42,自引:0,他引:42  
Subjective well-being (SWB) is evaluation of life in terms of satisfaction and balance between positive and negative affect; psychological well-being (PWB) entails perception of engagement with existential challenges of life. The authors hypothesized that these research streams are conceptually related but empirically distinct and that combinations of them relate differentially to sociodemographics and personality. Data are from a national sample of 3,032 Americans aged 25-74. Factor analyses confirmed the related-but-distinct status of SWB and PWB. The probability of optimal well-being (high SWB and PWB) increased as age, education, extraversion, and conscientiousness increased and as neuroticism decreased. Compared with adults with higher SWB than PWB. adults with higher PWB than SWB were younger, had more education, and showed more openness to experience.  相似文献

Many languages have no basic color term for "blue." Instead, they call short–wavelength stimuli "green" or "dark." We show that this cultural, linguistic phenomenon could result from accelerated aging of the eye because of high, chronic exposure to ultraviolet–B (UV–B) in sunlight (e.g., phototoxic lens brunescence). Reviewing 203 world languages, we found a significant relationship between UV dosage and color naming: In low–UV localities, languages generally have the word "blue"; in high–UV areas, languages without "blue" prevail. Furthermore, speakers of these non–"blue" languages often show blue–yellow color vision deficiency. We tested our phototoxicity hypothesis in a color–naming experiment, using computerized, colorimetric simulations of Munsell colors as viewed through clear and brunescent lenses. As predicted, our young subjects used "blue" as in English when the simulated lens was clear, but named colors as in tropical languages when the lens was dense. Our within–subjects design precludes a cultural explanation for this result.  相似文献
