Can young children, forming expectations about the social world, capture differences among people without falling into the pitfalls of categorization? Categorization often leads to exaggerating differences between groups and minimizing differences within groups, resulting in stereotyping. Six studies with 4‐year‐old children (N = 214) characterized schematic faces or photographs as falling along a continuum (really mean to really nice) or divided into categories (mean vs. nice). Using materials that children naturally group into categories (Study 3), the continuum framing prevented the signature pattern of categorization for similarity judgments (Study 1), inferences about behavior and deservingness (Studies 2 and 5), personal liking and play preferences (Study 4), and stable and internal attributions for behavior (Study 6). When children recognize people as members of continua, they may avoid stereotypes. 相似文献

Concept acquisition in the human infant. 总被引：1，自引：0，他引：1
The ability of 18-, 24-, and 30-week-old infants to learn conceptual categories regarding adult female faces was examined using a habituation paradigm. Little evidence for conceptual categorization occurred at 18 or 24 weeks, but at 30 weeks infants learned to respond to "a specific female face regardless of orientation" and to "female faces in general." 相似文献

Superordinate categorization via association with a common response was studied in pigeons. Original training paired disparate classes (e.g., people + chairs and cars + flowers) with a common response (Responses 1 and 2, respectively). Reassignment training taught new responses (Responses 3 and 4, respectively) to one component class from each pair (e.g., people and cars). Superordinate categorization was documented in testing when the pigeons made the same responses to the stimuli that were withheld in reassignment training (e.g., chairs and flowers) as they did to the reassigned stimuli themselves (e.g., people and cars) and when the birds transferred these discriminative responses to novel stimuli from all four component classes. Reassignment training with novel stimuli produced effects that were similar to those of reassignment training with familiar stimuli. Superordinate categorization via association with a common response is thus a robust effect that generalizes to novel stimuli from each of the component classes. 相似文献

We call for a shift from a content-oriented approach to a process-oriented approach to the study of categorization in infancy. Although gains have been made in our understanding of infant categorization by evaluating the categories to which infants respond, further understanding of infant categorization, and how categorization changes with development, requires that we more directly assess infants' category formation. We argue that two directions for future research will continue to enhance our understanding of categorization in infancy (and beyond). First, contextual variations (e.g., the effects of task, stimuli, and other factors) on infants' categorization must be better understood. Second, we must more directly evaluate the kinds of information infants use when forming categories, as well as how their use of such information changes with age, task, and so forth. We argue that these two foci will provide clearer understanding of the origins and early development of categorization. 相似文献

The literature on the role of models and theories in physics suggests that multiple models, abstract or concrete exist for a particular phenomenon. These models could be organized into hierarchies describing the entire physics domain (Giere 1994). Hierarchies of concepts have been used in other domains with success; however, criteria for a hierarchy of models in physics and theory's role are unclear. Therefore, research was conducted to describe the knowledge structures of experts, intermediates, and novices. A reiterative categorization task required subjects to sort and re-sort physics problems. The proportions of theory- and model-based categories created by the subjects were compared. Novices created hierarchies of model-based categories. Both intermediates and experts created theory-based categories at the highest, most abstract, level but combined model- and theory-based categories at middle and lower levels. These results support a representation of physics knowledge in which a hierarchy of models is organized by theory-based categories. 相似文献

This study evaluated the significant contents and concepts of the Biopsychosocial Assessment Method (MAB) as they relate to the International Classification of Functioning, Disability, and Health (ICF) and the connection between the Geriatric Core Set (GCS) and the different issues of the MAB. We linked the 56 items of the MAB to ICF and GCS categories according to published rules. The most significant concepts included in the MAB enabled the connection of 83 items to the ICF's categories. It was possible to establish a connection with all the components of the ICF except the Body Structures component. Of the 123 categories in the GCS, about 30% did not establish connections with MAB items. The results of this study show that—much like the ICF—the MAB is a tool based on the biopsychosocial model, allowing for a comprehensive and integrated assessment of the different components of functioning. Now, the MAB is the most utilized tool for the evaluation of the geriatric population in Portugal. Thus, it is of the utmost importance that we analyze its results in order to enhance its capabilities. It can then contribute to the creation of a shortened Core Set by the World Health Organization (WHO). 相似文献

Holyoak and Koh (1987) and Holyoak (1984) propose four critical tasks for analogical transfer to occur in problem solving. A study was conducted to test this hypothesis by comparing a multiple components (MC) approach against worked examples (WE) in helping students to solve algebra word problems in chemistry classes. The MC approach incorporated multiple components (symbolic equations, symbols, categorization, hint) in the source, or target, or both, to address the four analogical tasks. Different combinations of the components were tested in a series of four experiments. Symbolic equations (main component) fostered a mental construction of the problem in its solution mode. Categorization enabled an identification of the problem category. A hint in the target directed the learners to the source problem. The interaction between these components facilitated the mapping of the symbolic equations in the source onto the target, resulting in the superiority of the MC approach in fostering analogical transfer. Neither the main component alone nor the main component plus one sub-component was sufficient for analogical transfer. Hence for analogical transfer to occur, at least the main component (symbolic equations) and two sub-components (categorization and hint) are required. However, symbols may not have additional effects for transfer to occur. 相似文献

There have been relatively few single case studies concerned with the remediation of spelling deficits among developmental
impairments. Among these there have been a small number that targeted specific components of the spelling process and used
linguistic theories as theoretical underpinning for the development of remediation procedures. This single case study examines
remediation of writing skills and aims at evaluating two different lexically based intervention methods, one of which used
Optimality Theory as its basis. We applied a rule-based remediation and an intervention method using whole-word forms to a
child with selective impairments in the lexical-graphemic components. The investigation was done with words in which phoneme-grapheme-correspondences
in word final position change due to voicing neutralization. The individual exhibited a method- and item-specific effect with
respect to the rule-based method. In addition, a transfer effect to untreated items and a generalization effect to untrained
but related tasks was observed. The absence of a method-specific and a generalization effect for the whole-word form intervention
and the success of the rule-based method is determined by the specific cognitive component(s)s that constitute the source
of the deficit and the appropriateness of Optimality Theory to address this particular deficit. 相似文献

Combined with emotional expressions, eye gaze can provide essential information to indicate threat in the environment. The current study assessed the effects of eye gaze direction on infants’ neural processing of fearful and angry faces. Event‐related potentials were recorded from thirteen 7‐month‐old infants. Two face‐sensitive posterior components, the N290 and P400, as well as a frontocentral negative component (Nc), indicating attentional arousal, were sensitive to eye gaze direction and emotion. A larger Nc was observed for angry faces with direct compared to averted eye gaze. Fearful faces elicited a larger N290 than angry faces, whereas angry faces elicited a more prominent P400 regardless of eye gaze direction. The findings are discussed in terms of early social cognitive and neural development. 相似文献

Categorization theory helps make sense of writing placement. As developed by psychologists, social scientists, and language analysts, current theory suggests that human acts of categorization fall roughly under three models: classical, prototypical, and exemplar. Results of actual holistic scoring, however, show that readers behave as if the categories (scale points) had prototypical structure. In many ways, prototypical and exemplar categorization support a different writing-placement method, one more efficient than the holistic, a two-tiered sequence of quick, blind, and single readings followed by careful, informed, and multiple readings. The procedure is flexible and admits wide variations. Categorization theory itself, and standard research techniques associated with it, can be productive in inquiry into writing assessment. 相似文献

Social competency deficits are a core feature of autism spectrum disorders (ASDs). During the past several decades, a number of social skill interventions for students with ASD have emerged. However, over the past five years, three converging issues have brought increased attention to the need for social competence programming: (1) increased ASD incidence rates, (2) inclusion and integration trends, and (3) recent No Child Left Behind Act requirement regarding use of evidence-based practices. This article discusses current best practices in enhancing the social competence of learners with ASD. To this end, a review of the literature was conducted to: (1) define key behaviors related to social competence targeted by common interventions and (2) identify the core components and targets that are essential for effective social competence interventions. Searches done by hand and electronically were conducted to identify empirical reviews or summaries of effective social competence interventions from preschool to early adulthood. Eight reviews that encompass typically developing as well as those that specifically target ASD were chosen. Results of the review identified eight primary behavior categories most frequently targeted by social interventions across preschool, elementary, and secondary age groups. Additional analysis identified 11 core components consistently identified in the reviews. Explanation of categories as well as implications for future research and practice are explored. 相似文献

One hundred 18-month-olds were tested using sequential touching and following 4 different priming contexts using sets of toys that could be simultaneously categorized at either the basic or global level. An exact expression of the expected mean sequence length for arbitrary categories was derived as a function of the number of touches made, and a finite mixture model analytic method was also used to explore individual variability in categorization. Toddlers could categorize flexibly and spontaneously selected the level of categorization as a function of the prior prime. Perceptual Variability emerged as a predictor of the level at which infants subsequently categorized. The infants were also able to classify objects as members of both basic- and global-level categories simultaneously. 相似文献

认知语言学有关范畴化理论的构建以"家族相似性"为基础。但"家族相似性"作为构建范畴的基本原则不能贯彻到范畴的全部;在进行范畴层次划分时,仅依靠"网络交叉相似"无法确立上层范畴;非典型成员游离于范畴之间,使"范畴内部结构"成为一个自相矛盾的概念。这些进退维谷的状况,是范畴化理论的"瓶颈"所在。 相似文献

Electrophysiological correlates of infant recognition memory 总被引：4，自引：0，他引：4
Event-Related Potentials were recorded from 6-month-old infants in order to examine the electrophysiological correlates of recognition memory. In 1 study, infants were shown 1 face briefly, followed by the same face presented with high probability, and a novel face presented with low probability. 2 components were observed that distinguished between the novel and familiar events. Differences between these components in latency, polarity, and scalp topography led to the suggestion that 2 processes were involved in recognizing the stimuli. In a second study infants were again presented with 1 face briefly, followed by the same face and a novel face presented with equal probability. 1 component at central scalp distinguished between the novel and familiar events. In a third study, infants were simply presented with 2 previously unseen faces equally often. Infants responded as if the faces were identical, suggesting that previous experience with 1 stimulus directs infants' attention to the novel stimulus during the test portion of the task. The extent to which the observed responses reflect the updating of working memory is discussed, as is the extent to which infants' electrophysiological response to stimulus novelty and uncertainty resembles the adult's. 相似文献

Abstract The purpose of this article was to examine students' after-school pursuits in a categorization framework and to consider the association of the pursuits with achievement after disaggregating the data by ethnicity. Student pursuits were categorized as in- or out-of-school, academic or nonacademic, organized or unorganized instead of simply in or out of school. For example, varsity football would be categorized as in-school, nonacademic, organized. A sample of 8,305 8th- and 10th-grade students who were enrolled in both years and had complete data was drawn from the National Education Longitudinal Study (1988) data set. The authors used multiple regression to analyze the models by ethnic background and found that different pursuits had differing levels of association after disaggregating by ethnicity. Also, classifying all after-school pursuits into 1 or 2 categories masked important differences in their associations with achievement. 相似文献

Student responses to a large number of constructed response items in three Math and three Reading tests were scored on two occasions using three ways of assigning raters: single reader scoring, a different reader for each response (item-specific), and three readers each scoring a rater item block (RIB) containing approximately one-third of a student's responses. Multiple group confirmatory factor analyses indicated that the three types of total scores were most frequently tau-equivalent. Factor models fitted on the item responses attributed differences in scores to correlated ratings incurred by the same reader scoring multiple responses. These halo effects contributed to significantly increased single reader mean total scores for three of the tests. The similarity of scores for item-specific and RIB scoring suggests that the effect of rater bias on an examinee's set of responses may be minimized with the use of multiple readers though fewer than the number of items. 相似文献

We examined the experience of female ballet dancers and developed a theory about the origin and effects of this experience. Gordon's (1983) book Off Balance contains interviews and accounts of dancers' experience, and was used as the primary data source. Established methods of grounded theory were used to develop a theoretical account based on Gordon's text. We gleaned 167 meaning units from the text, and through categorization of these meaning units identified thematic components of dancers' experience as: (a) Fantasy Creatures; (b) Machines; (c) Slaves; (d) Children; and (e) Artists, each feeding our core construct of dancers as "A Breed Apart". Based on these categories we suggest some possible dynamics from which these experiences derive; we also discuss the study's limitations and implications for future research. 相似文献

Classifying people into categories not only helps humans simplify a complex social world but also contributes to stereotyping and discrimination. This research examines how social categorization develops by testing how language imbues with meaning otherwise arbitrary differences between people. Experimental studies (N = 129) with 2‐year‐olds showed that generic language—language that refers to abstract kinds—guides the development of social categorization. Toddlers learned a new category after hearing generic language about individuals who shared an arbitrary perceptual feature but not after hearing matched specific language, simple labels, or plural (but nongeneric) language about the same set of individuals. These findings show how subtle linguistic cues shape the development of social categorization. 相似文献
