儿童语言和认知(思维)发展的关系   总被引:9,自引:0,他引:9  
许政援 《心理学报》1994,27(4):347-353
在对幼儿从出生到3岁语言发展追踪研究和有关实验研究结果的基础上,比较、分析儿童语言和认知(思维)发展的各阶段及起作用的因素,探讨语言发展和认知发展的关系,提出以下几点看法:(1)儿童在1岁前(前语言期)的具体思维阶段有认知(有感知、记忆、表象和思维),但还没有真正的语言。这说明语言不是先于思维,也不是所有的思维都与语言相联系。但是,人类特有的抽象思维却与语言有着密切的联系。(2)认知(思维)发展是语言发展的基础。(3)认知(思维)发展和语言发展的关系是双向的,辩证的,是复杂地交互作用的。(4)应以辩证的唯物主义的观点来看语言和认知(思维)的产生。人类所以有语言,有高度抽象概括的思维,都源于人类的实践活动。  相似文献

Attention bias modification (ABM) protocols aim to modify attentional biases underlying many forms of pathology. Our objective was to conduct an effect size analysis of ABM across a wide range of samples and psychological problems. We conducted a literature search using PubMed, PsycInfo, and author searches to identify randomized studies that examined the effects of ABM on attention and subjective experiences. We identified 37 studies (41 experiments) totaling 2,135 participants who were randomized to training toward neutral, positive, threat, or appetitive stimuli or to a control condition. The effect size estimate for changes in attentional bias was large for the neutral versus threat comparisons (g = 1.06), neutral versus appetitive (g = 1.41), and neutral versus control comparisons (g = 0.80), and small for positive versus control (g = 0.24). The effects of ABM on attention bias were moderated by stimulus type (words vs. pictures) and sample characteristics (healthy vs. high symptomatology). Effect sizes of ABM on subjective experiences ranged from 0.03 to 0.60 for postchallenge outcomes, –0.31 to 0.51 for posttreatment, and were moderated by number of training sessions, stimulus type, and stimulus orientation (top/bottom vs. left/right). Fail-safe N calculations suggested that the effect size estimates were robust for the training effects on attentional biases, but not for the effect on subjective experiences. ABM studies using threat stimuli produced significant effects on attention bias across comparison conditions, whereas appetitive stimuli produced changes in attention only when comparing appetitive versus neutral conditions. ABM has a moderate and robust effect on attention bias when using threat stimuli. Further studies are needed to determine whether these effects are also robust when using appetitive stimuli and for affecting subjective experiences.  相似文献

Because even subtle forms of racial discrimination can damage well-being, identifying individual differences that shape this stress process is important. Dispositional forgiveness has been shown to influence how people perceive and react to interpersonal transgressions, yet its role in the context of racial discrimination has not received much research attention. In the current study, participants completed an initial measure of dispositional forgiveness and then considered a scenario that could be deemed racially discriminatory. Next, participants' perceptions of the scenario, negative affect, and cognitive performance were assessed. Dispositional forgiveness predicted all three outcomes such that more forgiving individuals were less likely to view the event as racially discriminatory and showed lower negative affect and greater cognitive performance after reading the scenario. Moreover, race moderated these relationships such that forgiveness played a more beneficial role for ethnic minorities than for whites.  相似文献

Abstract

Intentions to perform behaviors are influenced by beliefs about their consequences, but researchers have not addressed how such beliefs are cognitively organized. In 3 experiments, the authors tested the hypothesis that beliefs are organized according to whether they are favorable or unfavorable in regard to performing a behavior. In Experiment 1, a group of U.S. students first read a list of beliefs favorable and unfavorable to going to a vacation resort and then listed their beliefs about condom use. In Experiment 2, another group of U.S. students listed their beliefs about condom use. In Experiment 3, a 3rd group of U.S. students listed their beliefs about a novel behavior (asking the experimenter for candy). The results of all 3 experiments were consistent with the hypothesis that people cognitively organize their beliefs according to whether they are favorable or unfavorable to the behavior in question.  相似文献

The cognitive discrepancy model predicts that loneliness occurs when individuals perceive a difference between their desired and actual levels of social involvement. Using data from a sample of high school sophomore students, the present investigation was designed to go beyond previous research that has tested this model by examining the predicted nonlinear relationships between desired and actual social contact and feelings of loneliness. Analyses indicated that support for the cognitive discrepancy model of loneliness was found only for measures of close friendships. Specifically, the discrepancy between the students' ideal number and actual number of close friends was found to be related in a nonlinear fashion to feelings of satisfaction with close friendships and loneliness after control for the number of close friends. Implications of these findings for theoretical models of loneliness are discussed.  相似文献

Nielsen, T. R. Vogel, A., Gade, A. & Waldemar, G. (2012). Cognitive testing in healthy Turkish immigrants ‐ comparison of the RUDAS and the MMSE. Scandinavian Journal of Psychology 53, 455–460. Methods for culturally and linguistically appropriate cognitive testing of elderly minority populations are lacking in Europe. The aim of this study was to compare performance on the Rowland Universal Dementia Assessment Scale (RUDAS) and the Mini Mental State Examination (MMSE) in Turkish immigrants in Denmark and determine the impact of demographic and health‐related variables on test performance. A sample of non‐demented community‐dwelling Turkish immigrants was recruited from the greater Copenhagen area. All participants completed a structured interview regarding demographic, physical and mental health status, as well as measures of depression and acculturation, and cognitive testing with the RUDAS and the MMSE. A total of 76 non‐demented participants aged 50 or more were included in the study. The mean performance on the RUDAS and the MMSE was 26.8 (SD 2.4) and 23.7 (SD 4.3), respectively. In group comparisons, correlation analyses and regression analyses, level of schooling represented a more significant variable for RUDAS and MMSE performance than any other variable. However, the impact of schooling was considerably more pronounced on the MMSE and the test was not found to be a valid measure of general cognitive function in subjects with less than five years of schooling. Although not entirely free of educational bias, the RUDAS can be a valuable supplement to the MMSE for assessment of general cognitive function in Turkish minority populations.  相似文献

Drawing on a broad, multidimensional conceptualization of subjective well-being, this study examined the power of childhood general cognitive ability to predict life satisfaction, satisfaction with eight individual life domains, and the frequency of experiencing positive and negative affect in middle adulthood. Data were obtained from a representative Luxembourgish sample (= 738; 53% female) in a longitudinal study conducted in 1968 and 2008. Childhood general cognitive ability was unrelated to life satisfaction, negatively related to negative affect and satisfaction with free time, and positively related to positive affect and satisfaction with some of the life domains associated with socioeconomic success (i.e. finances, self, housing, work, or health). This predictive power persisted even when childhood socioeconomic status was controlled.  相似文献

The neurophysiological mechanisms underlying superior cognitive performance are a research area of high interest. The majority of studies on the brain-performance relationship assessed the effects of capability-related group factors (e.g. talent, gender) on task-related brain activations while only few studies examined the effect of the inherent experimental task performance factor. In this functional MRI study, we combined both approaches and simultaneously assessed the effects of three relatively independent factors on the neurofunctional correlates of mental rotation in same-aged adolescents: math talent (gifted/controls: 17/17), gender (male/female: 16/18) and experimental task performance (median split on accuracy; high/low: 17/17). Better experimental task performance of mathematically gifted vs. control subjects and male vs. female subjects validated the selected paradigm. Activation of the inferior parietal lobule (IPL) was identified as a common effect of mathematical giftedness, gender and experimental task performance. However, multiple linear regression analyses (stepwise) indicated experimental task performance as the only predictor of parietal activations. In conclusion, increased activation of the IPL represents a positive neural correlate of mental rotation performance, irrespective of but consistent with the obtained neurocognitive and behavioral effects of math talent and gender. As experimental performance may strongly affect task-related activations this factor needs to be considered in capability-related group comparison studies on the brain-performance relationship.  相似文献

The structural approach on social representations is known for the development of central core theory and its similarity with cognition-oriented sociopsychological perspectives, which has been a target of criticism. The approach has difficulty in dealing with the social dimension of knowledge and adopts a static notion of structure. Acknowledging those shortcomings, we present a revised structural conceptual model of social knowledge and social representations based on the consideration of normative and social identity processes, compatible with contributions of authors external to the classical structural approach, such as Wagner (holomorphy) and Lahlou (propagation model). After redefining the concepts of cognem and structure, we tackle thinking processes and the differences between personal and social representations, conceiving the latter as conventional codes linked to groups. Limitations of the perspective are discussed and research directions are indicated based on an understanding of structure that is broader than the one adopted by the classical approach.  相似文献
