Numerical abstraction by human infants 总被引:9,自引:0,他引:9
Across several experiments, 6- to 8-month-old human infants were found to detect numerical correspondences between sets of entities presented in different sensory modalities and bearing no natural relation to one another. At the basis of this ability, we argue, is a sensitivity to numerosity, an abstract property of collections of objects and events. Our findings provide evidence that the emergence of the earliest numerical abilities does not depend upon the development of language or complex actions, or upon cultural experience with number. 相似文献

Insides and essences: early understandings of the non-obvious 总被引:3,自引:0,他引:3
Insides and essences are both critical concepts for appreciating the importance of non-obvious entities: neither are observable, both contrast with external appearances, and both can be more important than external appearances. The present research examined understandings of insides and essences in 3- to 5-year-old children. In Study 1, children were asked questions requiring them to think about both the insides and the outer appearances of a series of objects. In Study 2, children were tested on their understanding that insides are typically more important than outer surfaces for an object's identity and functioning. In Studies 3, 4, and 5, children were tested on their understanding of innate potential, a concept that reflects understanding of an inborn essence. Contrary to the traditional view of children as externalists (cf. Piaget, 1951), these studies demonstrate that by age 4 children have a firm grasp of the importance of both insides and essences. Even by age 3 children reason clearly about the inside-outside distinction. These results suggest that preschool children attend to non-obvious features and realize their privileged status. They may also indicate a more basic predisposition toward psychological essentialism in young children. 相似文献

Beliefs about the origins of human psychological traits 总被引:5,自引:0,他引:5
The development of children's reasoning about the origins of human psychological traits was investigated across 4 studies with a total of 316 participants ranging in age from kindergartners to 5th graders and adults. The primary methodology was a switched-at-birth task (L. A. Hirschfeld, 1995), which poses a hypothetical nature-nurture conflict. Two major issues were addressed: (a) the extent to which psychological traits are viewed as a product of environmental influence and (b) whether individuals can be primed to think about the origins of psychological traits in particular ways. Results suggest that there is an age-related increase in the tendency to make distinctions among different psychological traits and that over time, individuals come to believe that psychological traits are determined primarily by nurture. Results also show that young children's beliefs about trait origins are subject to subtle priming effects before an adultlike response pattern is seen. 相似文献

This paper describes the process of two groups of students from high schools located in the immediate vicinity of the World Trade Center grappling to make sense of the events of September 11 through the creation of a documentary chronicling their experiences. The process of creating these videos mirrored the process and curative factors of a psychotherapy group in a non-stigmatizing, innovative, and accessible format, one generated by the students themselves with the assistance of professionals in the visual and performing arts. After reviewing the literature on the potential impact of violence on adolescents and the use of group treatment, especially in school settings, as an optimal choice for this population, we describe the distinctive process of the two separate groups of students, each culminating in different expressions of their very personal experience of September 11. We understand and contextualize their process through the lens of the therapeutic dynamics and elements of group work. 相似文献

Nonverbal Counting in Humans: The Psychophysics of Number Representation 总被引:12,自引:0,他引:12
In a nonverbal counting task derived from the animal literature, adult human subjects repeatedly attempted to produce target numbers of key presses at rates that made vocal or subvocal counting difficult or impossible. In a second task, they estimated the number of flashes in a rapid, randomly timed sequence. Congruent with the animal data, mean estimates in both tasks were proportional to target values, as was the variability in the estimates. Converging evidence makes it unlikely that subjects used verbal counting or time durations to perform these tasks. The results support the hypothesis that adult humans share with nonverbal animals a system for representing number by magnitudes that have scalar variability (a constant coefficient of variation). The mapping of numerical symbols to mental magnitudes provides a formal model of the underlying nonverbal meaning of the symbols (a model of numerical semantics). 相似文献

Sloutsky and Fisher (2012) attempt to reframe the results presented in Noles and Gelman (2012) as a pure replication of their original work validating the similarity, induction, naming, and categorization (SINC) model. However, their critique fails to engage with the central findings reported in Noles and Gelman, and their reanalysis fails to examine the key comparison of theoretical interest. In addition to responding to the points raised in Sloutsky and Fisher's (2012) critique, we elaborate on the pragmatic factors and methodological flaws present in Sloutsky and Fisher (2004) that biased children's similarity judgments. Our careful replication of that study suggests that, rather than measuring the influence of labels on judgments of perceptual similarity, the original design measured sensitivity to the pragmatics of task demands. Together, the results reported in Noles and Gelman and the methodological problems highlighted here represent a serious challenge to the validity of the SINC model specifically and the words-as-features view more generally.

This set of seven experiments examines reasoning about the inheritance and acquisition of physical properties in preschoolers, undergraduates, and biology experts. Participants (N = 390) received adoption vignettes in which a baby animal was born to one parent but raised by a biologically unrelated parent, and they judged whether the offspring would have the same property as the birth or rearing parent. For each vignette, the animal parents had contrasting values on a physical property dimension (e.g., the birth parent had a short tail; the rearing parent had a long tail). Depending on the condition, the distinct properties had distinct functions (“function‐predictive”) were associated with distinct habitats (“habitat‐predictive”), or had no implications (“non‐predictive”). Undergraduates' bias to view properties as inherited from the birth parent was reduced in the function‐ and habitat‐predictive conditions. This result indicates a purpose‐based view of inheritance, whereby animals can acquire properties that serve a purpose in their environment. This stance was not found in experts or preschoolers. We discuss the results in terms of how undergraduates' purpose‐based inheritance reasoning develops and relates to larger‐scale misconceptions about Darwinian evolutionary processes, and implications for biology education. 相似文献

Psychological essentialism in children 总被引:9,自引:0,他引:9
Gelman SA 《Trends in cognitive sciences》2004,8(9):404-409
Psychological essentialism is the idea that certain categories, such as "lion" or "female", have an underlying reality that cannot be observed directly. Where does this idea come from? This article reviews recent evidence suggesting that psychological essentialism is an early cognitive bias. Young children look beyond the obvious in many converging ways: when learning words, generalizing knowledge to new category members, reasoning about the insides of things, contemplating the role of nature versus nurture, and constructing causal explanations. These findings argue against the standard view of children as concrete thinkers, instead claiming that children have an early tendency to search for hidden, non-obvious features. 相似文献
