How people see the world, even how they research it, is influenced by beliefs. Some beliefs are conscious and the result of research, or at least amenable to research. Others are largely invisible. They may feel like "common knowledge" (though myth, not knowledge), unrecognized premises that are part of the surrounding culture. As we…

Assessed 3- to 7-year-old children's sensitivity to logical necessity by contrasting performance in insufficient and sufficient information conditions. A search task used in Experiments 1 and 2 allowed children to search for additional information in insufficient conditions. A judgement condition used in Experiment 2 required a "can't tell"…

This study investigated how 15 preadolescents and adolescents with autistic spectrum disorder (ASD) performed on false belief tasks that included social inferencing of psychological states as well a logical inferencing of physical states. Unlike the control groups, the ASD group performed better on the social inferencing tasks and use of a prompt…

Assesses three sets of Piagetian exclusion operations (of varying the independent variables, of holding the independent variable constant, and tautology) and of levels of thought (concrete through formal) in 33 fifth graders, 27 sixth graders, and 31 seventh graders. (HOD)

This paper describes the development and characteristics of structural interview procedures designed to aid researchers in investigating children's understanding of their logical arguments. The procedures comprise a system which assesses verbal expression, understanding of implication, and ability to reason logically; it also assesses…

Ordering theory was used in two studies to empirically determine hierarchies of developmental precedence for Piaget's 16 logical combinations. In study 1, subjects (N=94) responded to statements about odd and even numbers; in study 2, 30 subjects responded to statements about line segments. Results are reported and discussed. (Author/JN)

Reasoning and logical thinking can be defined and explained from different perspectives. Three approaches are reviewed in this report; they are: (1) the logical structure approach; (2) the Piagetian approach of developmental stages; and (3) the information processing or memory approach. Four hypotheses related to these approaches were investigated…

Comparison of elementary grade students with (N=42) or without (N=42) learning disabilities (LD) on their logical-mathematical structures of thought found that, though both groups generated grouping relationships, children with LD tendered to generate solutions showing less coordinated structures of thought. For both groups, scores on the…

To investigate the development of function concepts and their relation to mathematical and logical abilities typically acquired during the age period of five to seven years, children were tested on nonnumerical function tasks, numerical tasks, and aspects of logical reasoning. (PCB)

The interview-about-instances technique was used to investigate the conceptual frameworks that 17 Form Four Southeast Asian students held about forces acting on an object at rest or in motion. Results show a number of alternate frameworks which are similar to those found in research conducted in western countries. (Author/JN)

As comprehension failure results whenever readers are unable to infer missing causal connections, recent comprehension research has focused both on assessing the inferential complexity of texts and on investigating students' developing ability to infer causal relationships. Studies have demonstrated that texts rely on four types of causal…

Measurements of formal reasoning and principled moral reasoning ability were obtained from a sample of 99 tenth grade students. Specific modes of formal reasoning (proportional reasoning, controlling variables, probabilistic, correlational and combinatorial reasoning) were first examined. Findings support the notion of hierarchical relationships…

Reports the use of a memory load-interference paradigm and the easy-to-hard paradigm as converging operations to study capacity limitations in five- to six-year-old's reasoning. Concludes that transitive inference ability in children is capacity limited. (HOD)

Offers a theory of how commonsense reasoning about motion may develop. Takes as fundamental the basic categories: action, object, space, cause, time, and movement. Suggests that very primitive elements could combine to provide schemes of motion recognizable in psychological accounts of infancy and generate prototypes of and rules for motion. (DK)

Reports on two studies during which 6-, 8-, and 10-year-old children were interviewed about three different types of regularities or rules: social conventions, physical laws, and logical necessities. Shows that older children made more distinctions between social and nonsocial items than did younger children. (HOD)
