When Experimental Findings Conflict with Everyday Observations: Reflections on Children''s Category Learning

Attempts to reconcile the ease with which young children naturally learn everyday categories with their frequent difficulty in acquiring artificial categories in the laboratory have taken different forms. Kemler Nelson suggested that one reason for the discrepancy may be that many everyday object categories have a family-resemblance structure that can be learned by means of a holistic mode of processing. While Ward et al. have recently questioned this account of why children learn family-resemblance categories easily, conclusions based on their laboratory data fail to provide a good explanation of the real-world case. Accordingly, it is suggested that the laboratory family-resemblance task used by these previous investigators may be unrepresentative and may fail to mimic crucial aspects of the everyday category-learning context. It is also suggested that aspects of Ward et al.'s methodology may lead them to underestimate holistic (or nonselective) processing.     

Children and Adults Learn Family-Resemblance Categories Analytically

3 experiments examined the modes of processing used by children and adults in learning family-resemblance categories. The materials were cartoon faces (Experiments 1 and 2) and bugs (Experiment 3) divided into categories that possessed no single defining attributes, but rather several characteristic attributes that were each partially predictive of category membership. The categories were structured so that a holistic mode of processing in which the individual did not selectively weight any given attributes could have led to success. Nevertheless, preschoolers (Experiments 2 and 3), first and third graders (Experiment 1), and adult college students (all experiments) all exhibited primarily analytic modes of learning that consisted of single- and dual-attribute approaches. Although the proportion of analytic learners among the preschoolers was lower than among the adults in Experiment 3, in no case were holistic modes of learning evident. The results are discussed in terms of their implications for young children's apparent relative success in learning natural categories. It is suggested that children's success in learning real-world categories may be based, in part, on an interaction between a basically analytic processing style and natural category structures that provide many partially informative attributes.     

What is "high"? The development of reference points for "high" and "low"

Young children have been characterized as interpreting relative adjectives as if they were nominal or categorical terms. The categorical interpretation of relative terms, however, may be quite complex. Indeed, the mature understanding of relative terms would seem to include a complex system of reference points for the terms' categorical usages. In 5 experiments we examined the complexity of 3-5-year-old children's and adults' categorical interpretations. We specifically examined how reference points for the categorical interpretation of high and low are defined. The definition of reference points relative to the object judged, the vertical position of the observer, and the extent of vertical variation were assessed. 3 major developmental trends were observed: a trend from the application of the terms to only extreme values to their application to broader categories; a trend from nominal-like categories to ones defined flexibly relative to context (e.g., nature of object judged, and extent of vertical variation); and a trend from reference points functioning as focal points to their operating as directional category boundaries. In brief, the results suggest that the categorical usage of relative terms involves a rich and intricate knowledge system and that it takes children considerable time to acquire and organize the relevant pieces of knowledge.

Delay-induced bias in children's memory for location

Two experiments examined how imposing a delay between learning and reproducing locations influences children's memory for location. In Experiment 1, ninety-six 7-, 9-, and 11-year-old children and adults learned the locations of 20 objects in an open, square box divided into four regions by opaque walls. During test, participants attempted to place the objects in the correct locations without the aid of the dots that had marked the locations or the boundaries that had divided the space. The test phase began either immediately following learning or following a 12-min delay. As predicted by the Category-Adjustment model, bias toward category centers increased significantly following an intervening delay. Moreover, the magnitude of categorical bias followed a systematic U-shaped developmental pattern. Results from a second study (N = 72) replicated this developmental pattern. Discussion focuses on the implications of these results for understanding how children and adults remember locations.     

Hyperactivity and incidental memory: evidence for attentional diffusion

2 experiments examined hyperactive children's attentional diffusion, that is, their tendency to underfocus their attention during learning. In Experiment 1 hyperactive children correctly rejected more incorrect incidental information than their nonhyperactive peers, indicating they were more likely to process noncentral attributes. This type of diffuse attention did not interfere with hyperactive children's overall memory performance. Experiment 2 varied the difficulty level of encoding central information, either by limiting the time available for encoding it (brief vs. long) or by varying the meaningfulness of the central information (high associative value shapes vs. low associative value ones). Results showed that hyperactives outperformed nonhyperactives on incidental recognition only when the encoding demands of the central task were easy. Easy encoding permitted them to attend to incidental information without sacrificing central information. Taken together, the results of both experiments demonstrated the validity of the attentional diffusion hypothesis and indicate the need to assess the central processing demands associated with central and incidental learning in order to evaluate the extent of hyperactive children's attentional diffusion.     

'Being in the World': The event of learning

This paper employs an eclectic mix of paradigms in order to discuss constituting characteristics of young children's learning experiences. Drawing upon a phenomenological perspective it examines learning as a form of 'Being' and as the result of learners' engagement with the world in their own, unique, intentional manners. The learners' intentions towards their world are expressed in everyday activity and participation. A social constructivist perspective is thus employed to present learning as situated in meaningful socio-cultural contexts of the everyday, lived world and as a form of participation in those settings. These characteristics of learning are brought together into a holistic, synthesised model, a Gestalt of learning. The proposed synthesis has relevance for and is applicable to educational contexts as a means of making sense of children's learning experiences and of promoting and facilitating them.     

Classroom and Grade Level Differences in the Stability of Teacher Expectations and Perceived Differential Teacher Treatment

Using two independent samples of urban elementary school children from Grades 1, 3, and 5, this study explored the long-term stability of classroom learning environments that differ in the extent of differential teacher treatment favoring high achievers over low achievers, as reported by students. Classroom differences ('high' versus 'low') in perceived differential treatment were highly stable from fall to spring in Grades 3 and 5, but not in Grade 1. Stability in (a) individual children's reports of differential treatment, and (b) teacher expectations for children's year-end reading achievement was accentuated in classrooms where differential treatment was pronounced early in the year, particularly in the higher elementary grades. Findings suggest that there would be heightened risk for problematic teacher expectancy effects and other maladaptive learning outcomes in these classrooms, because stable or rigid performance expectations are coupled with classroom instructional patterns that consistently convey these expectations to children. In contrast, risk is likely to be reduced in classrooms where high and low achievers are treated more equitably in the eyes of children, because teachers' expectations for children are more flexible, and children take longer to discern differences in treatment. The overall consistency of findings in two samples supports the generalizability of the conclusions reached.     

Learning Science through Investigations: An Experience with Hong Kong Primary School Children

This paper reports on a study of children learning science through investigations. Because many skill-type performances depend upon knowing and understanding the relevant content, this paper addresses both the children's understanding of scientific ideas and their performance of the science process skills. Twenty-four written records of investigations conducted by Hong Kong primary school children were studied to explore children's cognitive processes in scientific investigations. The paper concludes with a model that provides useful information about aspects of children's cognitive understanding and the practical processes that are necessary for scientific investigation.

Emotion discourse, social cognition, and social skills in children with and without developmental delays

This study examined parent-child emotion discourse, children's independent social information processing, and social skills outcomes in 146 families of 8-year-olds with and without developmental delays. Children's emergent social-cognitive understanding (internal state understanding, perspective taking, and causal reasoning and problem solving) was coded in the context of parent-child conversations about emotion, and children were interviewed separately to assess social problem solving. Mothers, fathers, and teachers reported on children's social skills. The proposed strengths-based model partially accounted for social skills differences between typically developing children and children with delays. A multigroup analysis of the model linking emotion discourse to social skills through children's prosocial problem solving suggested that processes operated similarly for the two groups. Implications for ecologically focused prevention and intervention are discussed.

Language delays, reading delays, and learning difficulties: interactive elements requiring multidimensional programming

Researchers have hypothesized four levels of instructional dialogue and claimed that teachers can improve children's language development by incorporating these dialogue levels in their classrooms. It has also been hypothesized that enhancing children's early language development enhances children's later reading development. This quasi-experimental research study investigated both of these hypotheses using a collaborative service delivery model for Grade 1 children with language difficulties from a socially and economically disadvantaged urban community in Australia. Comparing the end-of-year reading achievement scores for the 57 children who received the language intervention with those of the 59 children in the comparison group, the findings from this research are supportive of both hypotheses. The interrelationships between learning difficulties, reading difficulties, and language difficulties are discussed along with children's development in vocabulary, use of memory strategies and verbal reasoning, and the need for multidimensional programming.     

The effectiveness of multimedia programmes in children's vocabulary learning

The present experiment investigated the effect of three different presentation modes in children's vocabulary learning with a self-guided multimedia programmes. Participants were 135 third and fourth grade children who read a short English language story presented by a computer programme. For 12 key (previously unknown) words in the story, children received verbal annotations (written translation), visual annotations (picture representing the word), or both. Recall of word translations was better for children who only received verbal annotations than for children who received simultaneously visual and verbal annotations or visual annotations only. Results support previous research about cognitive load in e-learning environments, and show that children's learning processes are hindered by limited working memory. This finding implies a challenge for multimedia programmes designed for children and based on self-regulated learning.     

Children's Proportional Judgments: The Importance of "Half"

3 experiments are reported, all of which show the crucial importance of the "half" boundary in children's proportional judgments. In the first experiment 4-, 5-, 6-, and 7-year-old children had to judge which of 2 boxes of blue and white bricks was represented in a small picture. The proportion of blue to white bricks was different in the 2 boxes, and the question was whether the children could use these proportions to make their choices. The 6- and 7-year-old children solved the problem much more successfully when the proportions crossed the "half" boundary (e.g., 3/8 blue vs. 5/8 blue). The second experiment showed that discriminations involving half (e.g., 1/2 blue vs. 1/4 blue) are also easier than those that do not cross the "half" boundary for the 6- and 7-year-olds. The third experiment confirmed the results of the first 2 with pictures of different absolute sizes from each other. We conclude that "half" plays a crucial role in children's early proportional reasoning, and that the "half" boundary is to some extent similar to, though not as powerful as, the category boundaries discovered in speech perception.     

Social information processing, security of attachment, and emotion regulation in children with learning disabilities

This study examined the contribution of attachment security and emotion regulation (ER) to the explanation of social information processing (SIP) in middle childhood boys with learning disabilities (LD) and without LD matched on age and grade level. Children analyzed four social vignettes using Dodge's SIP model and completed the Kerns security scale and the children's self-control scale. Study results demonstrated major difficulties in SIP, lower attachment security, and less ER in children with LD compared to children without LD. Attachment as well as the interaction between attachment and ER emerged as important contributors to most SIP steps, suggesting that children with higher security who also have better ER skills will have better SIP capabilities along the different steps, beyond group inclusion. Results were discussed in terms of practical and clinical implications regarding the importance of mother-child attachment and ER skills for social cognitive capabilities in children with LD.     

A Time and a Place for Everything: A Discrete Systems Perspective on the Role of Children's Rough-and-Tumble Play in Educational Settings

This paper emphasizes the following points regarding the appropriate role of rough-and-tumble play (R & T) in educational settings. (1) There has been an important secular trend toward an increasing importance of adult supervision of children's play. As a result, children's R & T must be considered in the context of social values regarding the expected developmental significance of children's play. (2) R & T is an aspect of evolved systems that propel the children into enthusiastic interaction with their environment and can be reasonably supposed to have several beneficial influences on children's cognitive and social development. (3) R & T can be distinguished from aggression, and adult supervised R & T is potentially an important arena for learning the limits of appropriate R & T. (4) It is suggested that supervised educational settings should be concerned with socializing several discrete systems that underlie children's development, including the present emphasis on socializing children to be able to focus attention, inhibit behavior, and be neat and orderly. However, the purpose of the present paper is to present a case for socializing the systems underlying stimulus seeking, extroversion, sociability, and intellectual creativity as well.     

The Inheritability of Identity: Children's Understanding of the Cultural Biology of Race

4 experiments explored adult and grade school children's beliefs about inheritability of identity, particularly the "one-drop rule" that defines children of mixed-race parents as belonging to the racial category of the minority parent. In Study 1, 8- and 12-year-olds ( N = 32) and adults ( N = 43) were asked the category membership of mixed-race children and the degree to which they resembled each parent. Study 2 investigated whether the same-aged children ( N = 36) and adults ( N = 18) expected mixed-race children to have white, black, or intermediate features. Study 3 explored children's ( N = 46) expectations about the inheritability of the same properties in animals. Older children, like adults, were found to believe that mixed-race children have black racial features. Adults additionally believe that such children inherit the categorical identity of the minority parent. Study 4 repeated the same tasks with black and white children ( N = 39) attending an integrated school. Unlike children attending a predominantly white school, children in the integrated school (regardless of race) expect mixed-race children to have intermediate racial features.     

The Teacher's Role in Creating a Positive Verbal and Nonverbal Environment in the Early Childhood Classroom

Teachers play a critical role in establishing the verbal and nonverbal environment in the early childhood classroom. Within this article, children's literature is used as a vehicle for enhancing understanding of (a) how teachers talk to children, (b) how teachers allow children to talk to each other in positive and reinforcing or negative ways, and (c) how teachers help children talk to themselves about their learning and participation in class. The role of the teacher as a positive, conscious, and deliberate model of self-regulated learning is promoted.
