Kindergarten and first-grade children conserved physical attributes of inanimate objects more easily than the physical attributes of animate objects. Significant conservation differences between various animate objects also were found. (Author/RL)

Some young children presented with unidimensional and nonverbal conservation tasks were able to give a conservation response if they could answer with a picture instead of orally. (Editor)

Fifty-eight kindergarten children were assessed on traditional presentations involving the conservation of number and liquid. Each conservation test contained two different items and began with the stimuli quantitatively and perceptually equal. Two other conservation tasks for number and liquid with initial nonequivalence followed. Performance on…

A longitudinal investigation on development of conservation skills in 31 learning disabled (LD) children suggested that delayed transition between preoperational and concrete operational thought may be an important factor in understanding the continued school failure of learning disabled children. (Author/CL)

Hypothesized that there would be no significant sex differences in the performance of conservation tasks on substance or volume, among 247 Ibo-speaking Nigerian children. Attributed confirmation of the hypothesis to social change and greater sexual equality in this developing society. (GC)

Tests of intelligence, music audiation, auditory conservation, and visual conservation were administered to two first-grade classes. Data revealed that auditory conservation isn't significantly related to visual conservation but is significantly related to music aptitude, to IQ, and to the interaction of music aptitude and IQ. Instructional…

Describes an exploratory investigation of blind children's concepts of number, substance, length, area, weight, and volume conservation. Six children totally without sight or with only light perception were pretested, taught, and posttested twice using tasks specifically adapted for tactual presentation of materials. The children showed increased…

On the basis of these findings, both the measurement techniques of previous studies and Piaget's analysis of seriation are challenged. (Author)

The Concept Assessment Kit Conservation test was administered to 250 children from 6 countries. Results indicated that the age trends in conservation development for both males and females are fairly consistent from culture to culture. (DM)

Support for the contention that the empirical specification of the Piagetian concept of reversibility during training is not a requirement for conservation induction is presented in this experimental study. (Author/JKS)

A longitudinal study investigated children's ability to infer, from initial and final relative numerosity information, which of four transformations of a stimulus array had occurred: addition, subtraction, expansion, or contraction. It was expected that performance would reflect a sequence of three levels in understanding the effects of addition…

Forty-eight kindergarten children were divided into four groups on the basis of their status (preoperational vs. transitional) and whether or not they received inversion-negation training. Results indicated no differences due to status, but differences due to training. Results do not confirm the contention that acceleration can only occur during…

The purpose of the present study was to determine if a developmental sequence could be established for the appearance of conservation. A series of four dimensional tasks and a conservation task were administered to 25 kindergarten girls and 25 kindergarten boys. The dimensional tasks tested understanding of comparative and superlative terms along…
