This study examined verbal and non-verbal features of mother-infant shared book reading in Australia during the first year of life and explored the relationship between these features and infant cognition. Mother-infant dyads were observed in this cross-sectional study reading an unfamiliar book in a laboratory setting when infants were aged 6…

Background: Impaired profiles of neurocognitive function have been consistently demonstrated among pediatric patients with bipolar disorder (BD), and may aid in the identification of endophenotypes across subtypes of the disorder. This study aims to determine phenotypic cognitive profiles of patients with BD Type I and II. Methods: Subjects (N =…

Discusses the inadequacies of the linguistic development theory called cognitive determinism and suggests instead the linguistic input hypothesis. Concludes that it is not either cognitive development or linguistic input that determines linguistic growth, but an interaction between them. (RM)

This study attempted to determine the functional components of rehearsal strategies in children's discrimination learning. When a discrimination list was given without rehearsal instructions, ability to discriminate situational frequencies predicted performance. Without rehearsal strategy, subjects' ability to discriminate between previous usage…

THE LEARNING OF VERBALLY CONDITIONED MATERIAL WAS STUDIED TO CLARIFY SOME OF THE CONDITIONS UNDER WHICH SUCH LEARNING IS ACCOMPANIED BY THE USE OF HIGHER MENTAL PROCESSES, AND THE CONDITIONS UNDER WHICH IT IS NOT. THE STARTING POINT FOR THIS RESEARCH WAS THE PREMISE THAT LEARNING IN VERBAL CONDITIONING CAN OCCUR EITHER WITH OR WITHOUT AWARENESS ON…

When taught to link sorting to self-instruction ("I'm looking for blue triangles") children show perfect accuracy in sorting. This study investigated if this performance would generalize to new stimuli. One participant showed near-perfect generalization to all new stimulus sets (shapes, letters, pictures); two had difficulty with…

After opening with a 13-page review of the literature, the document's main emphasis is on the three experiments included in this report. The specific rationale, procedures, and results of the three studies comprise the major portion of the document. The general purpose of Experiment 1 was to ascertain the effects of prior relevant subject matter…

Discusses and refutes Novak's arguments against Piaget's theory of intellectual development in favor of Ausubel's theory of meaningful verbal learning. (GA)

Chapters contained in this volume, each with a list of references appended, are: "Scientific Psychology in Transition" by Gregory A. Kimble; "Higher Mental Processes as the Bases for the Laws of Conditioning" by Eli Saltz; "Reification and Reality in Conditioning Paradigms: Implications of Results When Modes of Reinforcement are Changed" by David…

Naming tasks were used in two studies to test for conceptual organization in young children by comparing the latencies for naming objects in primed vs. non-primed conditions. In the primed condition, a taxonomic category was primed by prior activation of a coordinate member of the same category. In Study 1, 54 kindergarten children were randomly…

Investigated children's understanding of meaning of the cognitive verb "know" (as defined by an abstractness and conceptual difficulty hierarchy). Found that knowledge increased with development, and low levels of meaning were mastered before high levels, and more rapidly. Understanding in audio-taped stories was more difficult than in video-taped…
