This paper attempts to investigate five and six-year old children's ability to formulate logical reasoning. More specifically, our interest focuses on the investigation of young children's ability to use arguments based on logical reasoning. Can pre-school children build arguments based on logical reasoning such as deductive reasoning, or forms of…

The integrated theory of numerical development posits that a central theme of numerical development from infancy to adulthood is progressive broadening of the types and ranges of numbers whose magnitudes are accurately represented. The process includes four overlapping trends: (1) representing increasingly precisely the magnitudes of non-symbolic…

On belief-desire reasoning tasks, children first pass tasks involving true belief before those involving false belief, and tasks involving positive desire before those involving negative desire. The current study examined belief-desire reasoning in participants old enough to pass all such tasks. Eighty-three 6- to 11-year-olds and 20 adult…

Piaget's conceptualization of concrete and formal operations is presented. It is contended that Piaget has obfuscated logic, metaphysics and methodology. (MS)

Proster Theory is a theory of learning which has been proposed by Leslie A. Hart (1975). The theory is based on the functions of the brain. Learning is seen as the formation of programs, which are simply sequences of instructions by which the brain directs the muscles, sense organs, or other portions of the neurological system. Programs which are…

This study was concerned with distinguishing between two kinds of immature reasoning, both of which lead children to draw the same conclusions from arguments and which, therefore, cannot be distinguished by the usual tests. A total of 20 second-graders and 16 sixth-graders were tested on a logic game in which winning depended on drawing correct…

The purposes of this study were twofold: (1) to investigate the effect of movement for several inanimate objects on children's judgments of "aliveness;" and (2) to examine the nature of explanations given by three age groups of children in support of their judgments as to whether animate and inanimate objects were "alive" or…

This annotated bibliography attempts to answer the following questions: (1) What is criticial thinking? (2) Can it be taught and to whom? (3) Which methods are most practical for teaching critical thinking to secondary students? and (4) Can its acquisition be tested? The first question researches the literature for a definition of the term. The…

A modified version of Inhelder's and Piaget's bending-rods task was administered twice in succession to 9-, 11-, and 13-year-olds. Subjects were then categorized as spontaneous, latent, or nonusers of the formal operational control-of-variables strategy according to whether they used the strategy on the first, second, or neither administration.…

Reevaluates literature on the development of transitive inference in light of theoretical and methodological criticisms, and examines two aspects of the Piagetian account of the development of this cognitive ability. Criticism leveled is based on the observations that ability to make transitive inferences is not age-related and that children and…

Provides clarification of the Piagetian theory of the development of conservation and reviews the state of knowledge regarding the theory. It is concluded that reasonable evidence exists suggesting that conservation by identity precedes and induces the emergence of conservation by inversion and compensation. (Author/DB)

Even among individuals operating at Piaget's highest cognitive level (Formal Operations Stage) there is a range of behaviors on important cognitive characteristics. Various substages and their performance criteria are suggested. (JD)

Nine- to 18-month-old infants were presented with simple two-location manual search tasks involving invisible displacements of objects with sequence of displacements occurring before infants search. Results provided insights into age differences associated with development of logical search strategies, information-processing skills, and temporal…

Eight experiments were conducted to examine 3- and 3.5-month-old infants' responses to occlusion events. The results revealed two developments, one in infants' knowledge of when objects should and should not be occluded and the other in infants' ability to posit additional objects to make sense of events that would otherwise violate their…
