PIAGET HAS BEEN CONCERNED WITH THE ASSESSMENT OF THE PRESENCE OR ABSENCE OF CONSERVATION AND RELATED PROCESSES, BUT HE HAS NOT FOCUSED EXPERIMENTALLY ON THE FACTORS WHICH CAN ACCOUNT FOR THE LEARNING OF CONSERVATION. TO INVESTIGATE SUCH FACTORS, RESEARCH WAS CONDUCTED (1) TO DETERMINE THE RELATIVE EFFECTIVENESS OF TWO PARTICULAR GROUP TRAINING…

Two experiments comprised this study comparing the ability of children from ages 4 to 12 years to discriminate the order in which items from a previously presented sequence of stimuli had been presented. The hypotheses were that the discrimination of recency (DR) improves with age, that broader separations of test items are easier to discriminate…

Reports the results of two experiments dealing with children's visual and tactual performance. In the first task, after several presentations of a series, the tactual group made almost errorless discriminations. But with memory demands, tactual performance became poorer than visual performance. Found a large developmental difference. (JAC)

Compared the processing of rapid auditory stimuli on two-tone auditory discrimination tasks by 7- to 11-year-olds with learning impairments (LI) and those without learning impairments (non-LI). Found that LI children committed more errors, but the effects of timing were comparable. Obtained same results with a sample of good and poor readers. Task…

The research concerned the association of neutral objects, such as nonsense syllables, with rewards, such as money and candy, in children. Thirty-six subjects were obtained from grades two through six of local public elementary schools in Nashville, Tennessee. Associations between neutral objects and rewards were formed in a task concerning…

One control group and eight experimental groups, each composed of 12 first grade children, participated in this experiment. It was designed to investigate the effects of frequency of reinforcement and repeated evaluation of stimuli on the conditioning of preferences. Each child participated in the experiment for seven consecutive school days. The…

Sex typing among preschool children was investigated by means of a complete experimental design to test which factors maintain sex-typed behaviors, to test whether sex-typed behaviors are learned, and to reduce sex typing. The complete experimental design, it is maintained, allows investigators to focus on the consequences of sex typing rather…

Two experiments studied the influence of an individual's cognitive style on concept identification. Subjects were high school males, classified into levels of cognitive style according to their performance on the Hidden Figures Test. For the first experiment, three non-overlapping groups of 30 each were required to classify figural patterns, which…

Reexamines the traditional role of observation in science and science education. Proposes that since observation is based on some view of the world, it is not innocent and unbiased, but theory-dependent. Discusses possible implications for the science curriculum when reconsidering the role and status of observation in science. (TW)

The occurrence of the two allomorphs of the indefinite article in standard English ("a" before nouns or noun clauses beginning with consonant sounds and "an" before those beginning with vowel sounds) is a concept similar to those studied in the general concept formation paradigm. The acquisition of this grammatical concept was examined using 80…

This guide provides group activities for teachers to aid in planning a multicultural curriculum for developing sensory perception in children. The guide emphasizes the cognitive processes involved in sorting out sensory data and the use of multicultural materials as resources for sensory experience. Activities are presented in six sections.…

Simple and complex learning and problem solving situations were employed with mentally retarded children and adults. In the Rotation-Discrimination Complex and the Size-Discrimination Simple experiments, upper and lower test achievement subgroups were subjected to two basic types of visual discrimination at different levels of task complexity.…

The purpose of this study was to empirically test a set of predictions implied by the Model of Conceptual Learning and Development using the concept of cutting tool. Four subtests were developed to assess a subject's ability to perform at each of four successive levels of concept attainment (concrete, identity, classificatory and formal). In…

The frequency theory of verbal discrimination learning makes no distinction between silent and spoken rehearsal. Further, the frequency theory predicts that the study-test method of list presentation is superior to the anticipation method. College students, performing under silent and spoken rehearsal conditions, learned 16 low-frequency…

Examines the relationship of grade level to children's ability to make musical discriminations when elements are presented simultaneously. Utilized a brief instructional period, listening tests, and singing tasks. Results indicated significant differences between grade level, types of discrimination, and musical interactions. Includes statistical…
