Factors Influencing Young Children's Ability to Detect Logical Inconsistencies in Oral Communications
Factors influencing the ability of kindergarten and first grade children to detect inconsistencies in communications were investigated in two experiments. The first experiment revealed that detection
Measuring Children's Age Stereotyping Using a Modified Piagetian Conservation Task
We examined five-year-old-children's age stereotyping using a modified Piagetian conservation task. Children were asked if two lines of objects were the “same” after one line had been made longer
Challenging "Early Competence": A Process Oriented Analysis of Children's Classifying
It is argued that the process of classifying is in fact very different for 5 and 10 year olds: whereas the older children treat the whole classification as a single unit composed of interrelated classes, the younger children proceed as though each class were independent of the others.
The child's understanding of functional relations in the domain of liquid quantity
Four liquid comparison tasks were designed to assess children's knowledge of functional relations, one-directional compositions of functional relations (greater + greater yield greater) and
Multiple classification performance of juvenile chimpanzees, normal children, and retarded children
The cognitive capacities of juvenile chimpanzees, normal children, and retarded children were evaluated by using a nonverbal, Piagetian-type multiple classification task, which suggests that the human children used a conceptual strategy, while the juvenile chimpanzees employed a perceptual strategy to solve the multiple classification problems.
Improving Children’s Logical and Mathematical Performance via a Pragmatic Approach
Deductive and logical reasoning is a crucial topic for cognitive psychology and has largely been investigated in adults, concluding that humans are apparently irrational. Yet, from a pragmatic
Embodied Action Improves Cognition in Children: Evidence from a Study Based on Piagetian Conservation Tasks
It is shown that active manipulation of the material helped children recognize quantity invariance in a higher proportion than when the demonstration was only observed, which emphasizes how active participation benefits cognitive processes in learning contexts, promoting autonomy, and agency during childhood.
Repetition Increases Children's Comprehension of Television Content—Up to a Point
Two studies examined the effects of repeated viewing on children's comprehension of videos. In Study 1, 72 children aged 6–8 watched The Sword in the Stone. Afterwards, children who had seen the film
Why Cannot Children See as the Same What Grown-Ups Cannot See as Different?— Early Numerical Thinking Revisited
Based on close observations of two 4-year-old children responding to their parents' requests for quantitative comparisons, we offer a "participationist" account of the origins and development of
Early reasoning about competence is not irrationally optimistic, nor does it stem from inadequate cognitive representations.
Young children’s reasoning about competence and achievement often seems out of step with reality. For instance, after failing to solve four puzzles in a row, most 3and 4-year-olds are nevertheless

The experiment was conducted in two sessions over two successive days on 90 children with a mean age of 5-1. All Ss were given pretests and posttests of conservation of number, length, and substance.

Some clues to the nature of semantic development
Studies of comprehension of the quantifiers all and more are reported. The subjects were children between the ages of three and five. There were two main conditions. In one of these the objects to

The aim of this study was to determine whether a group of normal English speaking children and a sample of mentally retarded children and adults, would show the same general trends in development of pre-number concepts as Piaget's subjects.
The Ontogenesis of Speech Acts.
A speech act approach to the transition from pre-linguistic to linguistic communication is adopted in order to consider language in relation to behaviour generally and to allow for an emphasis on the
Utterer’s Meaning, Sentence-Meaning, and Word-Meaning
My aim in this paper is to throw light on the connection between (a) a notion of meaning which I want to regard as basic, viz. that notion which is involved in saying of someone that by (when) doing
The Child's Conception of Number
A stabilizing and support system for an augmenter cooling liner of a gas turbine engine is shown to include flange means which divide a cooling plenum formed between the cooling liner and an exhaust
