Young Children's Understanding of Addition Concepts

Children's knowledge of concrete versions of additive composition, commutativity and associativity was investigated in two studies. In Study 1, 24 four- to five-year-olds and 25 five- to six-year-olds judged the equivalence of conceptually related addition problems presented using groups of objects. In Study 2, 45 five- to six-year-olds judged related problems and solved addition problems. Both studies indicated that concrete versions of principles were salient to most children although associativity was more difficult than commutativity and there were considerable individual differences in children's understanding. Study 1 results indicated that schoolchildren were more accurate at recognising additive composition than preschoolers and Study 2 results suggested that commutativity knowledge was related to using advanced counting strategies for solving addition problems. Overall, the research supports the claim that examining early knowledge of addition principles provides important insights into children's emerging part-whole knowledge and mathematical development.     

Young Children's Understanding of the Mind-Body Distinction

4 experiments investigated children's understanding of the mind-body distinction. Children of ages 4 and 5 recognized not only the differential modifiability of changeable versus unchangeable human properties and bodily versus mental properties, but also the independence of activities of bodily organs from a person's intention (Experiment 1). When presented 3 types of causal explanations (i.e., intentional, vitalistic, mechanical), 6-year-olds chose most often as most plausible for bodily functions vitalistic explanations (i.e., those ascribing the phenomena to a relevant bodily organ's initiative and effortful engagement in activity); 8-year-olds chose the vitalistic explanations second most often, following mechanical ones (Experiment 2). However, 6-year-olds, as well as 8-year-olds and adults, did not always choose vitalistic explanations over intentional explanations (Experiment 3); whereas they tended to prefer vitalistic explanations for biological phenomena, they predominantly accepted intentional ones for psychological phenomena (Experiment 3A). These results suggest that children as young as 6 years of age have acquired a form of biology as an autonomous domain which is separate from that of psychology.     

Transfer in Young Children's Understanding of Spatial Representations

The creative and flexible use of symbols is a unique human ability. In order to use a symbol, one must understand the basic relation between the symbol and what it represents. How do young children come to appreciate such relations? One possibility is that insight into one symbolic relation helps children appreciate different ones. The 3 studies presented here support this possibility. In Experiments 1 and 2, both 2.5- and 3.0-year-old children showed transfer from an easy task that required appreciation of a model-room symbolic relation to a more difficult one, one that children their age typically do not appreciate. In Experiment 3, 2.5-year-olds showed transfer between symbol types: Experience with a model-room relation helped them appreciate a map-room relation. These transfer effects are consistent with the claim that early experience with symbolic relations contributes to symbolic sensitivity, a basic readiness to recognize that one object or event may stand for another.     

Young Children's Understanding of Thought Bubbles and of Thoughts

In a series of 4 studies, we explored preschoolers' understanding of thought bubbles. Very few 3-year-olds or 4-year-olds we tested knew what a thought-bubble depiction was without instruction. But, if simply told that the thought bubble "shows what someone is thinking," the vast majority of 3-year-olds and 4-year-olds easily understood the devices as depicting thoughts generally and individual thought contents specifically. In total, these children used thought-bubble depictions to ascertain the contents of characters' thoughts in a variety of situations; appropriately distinguished such depictions from mere associated actions or objects; described thought bubbles in the language of mental states; judged that persons' thoughts in these depictions were subjective in the sense of person-specific (and hence 2 people can have different thoughts about the same state of affairs); and judged that thought-bubble thoughts ( a ) were representational in the sense of depicting or showing some other state of affairs, ( b ) were mental and thus showed intangible, private, internal thoughts unlike real pictures or photographs, and ( c ) can be false, that is, can depict a person's misrepresentation of some state of affairs. We discuss the implications of these findings for young children's understanding of thoughts and thought bubbles, for their learning and comprehension of pictorial conventions, and for the use of thought bubbles to assess children's early understanding of mind.

Young Children's Understanding of Changes in Their Mental States

3-year-old children have difficulty reporting their past false beliefs. We investigated their ability to remember and report other types of past mental state, in particular, pretenses, images, perceptions, desires, and intentions. In a series of tasks, children were placed in one mental state, that state was changed, and they were asked to report the initial state. 4-year-olds were generally able to report all their past mental states, including beliefs. 3-year-olds were able to report past pretenses, images, and perceptions extremely well. They had great difficulty reporting past beliefs. Reporting past desires and intentions was more difficult than reporting pretenses, images, and perceptions, but slightly less difficult than reporting beliefs. The evidence suggests that 3-year-olds have difficulty understanding the nature of representation.     

Young Children's Emotion Comprehension and Theory of Mind Understanding

Research Findings: The present study investigated the relation between theory of mind (ToM) and emotion understanding among 78 children 4½ to 6½ years old (35 boys, 43 girls). ToM understanding was assessed using ignorance and false belief questions within an emotion-understanding task that evaluated children's abilities to recognize facial expressions and identify the external causes of emotions (happy, sad, angry, scared, and surprised), understand the role of beliefs and desires in emotion, and comprehend felt versus expressed emotions. Results indicated that children's understanding of the external causes of emotion, hidden emotions, and a reminder's influence on emotions improved with age and that children's understanding of the external causes of emotion related to ToM understanding. Practice or Policy: Findings suggest that programs that seek to promote children's socioemotional awareness could benefit from encouraging the development of children's understanding of the external causes of emotions to improve overall social cognition.

Revisiting Young Children's Understanding of the Psychological Causes of Behavior

In 1989, Miller and Aloise challenged the prevailing belief that preschoolers tend to explain others' behavior in terms of external events or a person's physical attributes and have little understanding of psychological causes. That review documented preschoolers' understanding of, and even preference for, psychological causes as part of an emerging renaissance in developmental social‐cognitive research. The present, updated review (97 articles, participant ages 3 months to 6 years) suggests the emergence of a transformative new perspective in which social‐cognition is balanced between social and cognitive aspects rather than tilted toward cognition. Recent research on infants' awareness of mental states, young children's understanding of social categories and their judgments of the trustworthiness of informants, and cultural context reveals various ways in which preschoolers' social‐causal reasoning is social.     

Young Children's Understanding of the Causes of Anger and Sadness

This study investigated kindergarten children's understanding of the causes of anger and sadness. Previous research has shown that before 6 or 7 years of age, children have difficulty distinguishing hypothetical situations designed to evoke anger from those designed to evoke sadness. In this project, 80 kindergarten children (ages 5-1 to 6-5, M = 5-10) predicted and explained protagonists' emotional responses to a variety of hypothetical events. The results showed that intentional harm was not the feature young children used to distinguish anger from sadness. Children predicted anger most often when they believed that protagonists could change undesirable situations and reinstate their goals and when children focused on the person or conditions that brought about undesirable situations. Children predicted sadness most often when they believed that goal reinstatement was impossible and focused on the losses that would ensue as a result.     

Young Children's Understanding of a Biological Basis for Parent-Offspring Relations

2 experiments evaluated whether young children understand that kinship implies, but does not guarantee, physical resemblance among family members. In Experiment 1, preschoolers expected adopted babies to share physical properties, but not beliefs and preferences, with their biological parents rather than with their adoptive ones. However, preschoolers in Experiment 2 recognized that shared properties per se do not guarantee kinship: a baby who looks like and lives with a woman is not her biological baby if he or she initially grew inside someone else, whereas a baby may neither resemble nor live with its biological parents. Overall, the results suggest that children expect parents and offspring to share physical properties, but understand that shared properties do not necessarily entail kinship. In both experiments, the extent of this understanding increased with age. However, preschoolers' overall performance supports the claim that some children at this age have a naive theory of biology. The results further suggest that the critical development in an understanding of kinship is acquisition of factual knowledge rather than structural change.     

Young Children's Understanding of "Remember" and "Forget"

3 studies examined young children's understanding that if one "remembers" or "forgot," one must have known at a prior time. In Study 1,4-year-olds but not 3-year-olds understood the prior knowledge component of "forgot"; both groups understood that a character with prior knowledge was "gonna remember." Study 2 controlled for the possibility that good performance on "remember" might be due to a simple association of remembering with knowledge. A significant number of 4-year-olds but not 3-year-olds understood that when 2 characters currently knew, the one with prior knowledge remembered, and that when neither character currently knew, the one with prior knowledge forgot. Study 3 made prior knowledge more salient by making the remembered or forgotten item visible to the subjects throughout. 4-year-olds performed near ceiling on both verbs, whereas 3-year-olds' performance did not differ from chance. The results are discussed in relation to children's developing understanding of the mind.     

Origin and Truth: Young Children's Understanding of Imaginary Mental Representations

In 2 studies, we address young children's understanding of the origin and representational relations of imagination, a fictional mental state, and contrast this with their understanding of knowledge, an epistemic mental state. In the first study, 54 3- and 4-year-old children received 2 tasks to assess their understanding of origins, and 4 stories to assess their understanding of representational relations. Children of both ages understood that, whereas perception is necessary for knowledge, it is irrelevant for imagination. Results for children's understanding of representational relations revealed intriguing developmental differences. Although children understood that knowledge represents reality more truthfully than imagination, 3-year-olds often claimed that imagination reflected reality. The second study provided additional evidence that younger 3-year-olds judge that imaginary representations truthfully reflect reality. We propose that children's responses indicate an early understanding of the distinction between mental states and the world, but also a confusion regarding the extent to which mental contents represent the physical world.     

Reading and Forgetting among Young Children

Kyöstiö, O. K. & Vaherva, T. (1969). Reading and Forgetting among Young Children. Scand. J. Educ. Res., 129‐146. The aim of this article has been to analyze learning to read and forgetting, and to determine an optimal time for starting primary school. The study is a follow‐up type, of an experimental nature, using kindergarten children as an experimental group, and primary and kindergarten children as control groups. The children were tested three times to measure their reading standard before and after a period of tuition, and after the summer vacation interval to determine forgetting. The results show that children are able to learn to read earlier than the present starting of school in Finland presumes. Factors which influence learning are intelligence, age, social status, and teaching method. The large number of drop‐outs from the sample groups diminish the value of the generalizations that can be made from the results.     

Understanding Young Children's Three‐Dimensional Creative Potential in Art Making

This article explores aspects of young children's three‐dimensional development in art making. Understanding young children's three‐dimensional awareness and development is often a neglected area of early childhood educators' education and practice and often children's creative potential is not fully realised. The present article is based on a small scale qualitative study which focused on understanding 5–6 year‐olds' representational intentions in three‐dimensional artworks, understanding of visual/design concepts and expressive use of media (scrap paper and mod roc). The findings of the study suggest that young children are able to create satisfying three‐dimensional representations giving emphasis on forms, uprightness, balance, movement and modeling of multiple sides.     

Young Children's Understanding of Fictional versus Epistemic Mental Representations: Imagination and Belief

In 2 studies, 3- and 4-year-old children's ability to reason about the relation between mental representations and reality was examined. In the first study, children received parallel false belief and "false" imagination tasks. Results revealed that children performed better on imagination tasks than on belief tasks. The second study demonstrated that, when various alternative explanations for better performance on the imagination task were controlled for, children still performed significantly better when reasoning about another person's imagination than when reasoning about another person's belief. These findings suggest that children's understanding that mental representations can differ from reality may emerge first with respect to representations that do not purport to represent reality truthfully.     

Young Children's Theory of Mind Predicts More Sharing With Friends Over Time

Children (predominantly white and middle class) between 3 and 6 years (M = 55.12 months, N = 145 at Time 1, N = 102 at Time 2) participated in the prosocial choice test at two time points approximately 10 months apart. Children could share with strangers, close friends, nonfriends, and in a control, no recipient condition. Children shared more rewards with friends over time. Age interacted with recipient type such that older children had a higher probability of prosocial allocations toward friends and strangers compared to younger children. Theory of mind (ToM) predicted more prosocial allocations to friends over time, and the youngest children with higher ToM scores showed the largest increase in sharing with friends over time.     

儿童文学对低龄儿童焦虑心理的干预

在很多人的心目中,童年是纯真美好的,但是目前我国儿童焦虑心理普遍存在并呈现低龄化发展趋势。不少儿童文学作品已经开始尝试去反映儿童的焦虑心理,对低龄儿童存在的压力进行了或多或少的释放。研究这一部分作品,对于我们拓宽儿童文学领域、深化儿童文学内涵、更新儿童文学认知具有重要的参考价值。     

A Comparison of Young Children's Understanding of Contradictory Representations in Pretense, Memory, and Belief

The present study examined the nature of young children's understanding of various mental representations. 3- and 4-year-olds were presented with story protagonists who held mental representations (beliefs, pretenses, and memories) that contradicted reality. Subjects chose 1 of 2 alternate " thought pictures " (depicting either the mental representation or reality) that reflected the mental state. While 4-year-olds performed relatively well on all scenario types, 3-year-olds chose the correct thought picture significantly more often for pretense and memory scenarios than for false belief scenarios. These results suggest that young children conceptualize pretense as involving mental representations, and that they have more difficulty understanding contradictory mental representations that purport to correspond to reality.
