Described are procedures used to assess reasoning in congenitally blind students. It is explained that the Piagetian Battery of Reasoning Assessments for concrete and formal or abstract thought measures the following basic abilities: reversability of thought, classifacatory thought, spatial orientation, and mental imagery.

Nouns are generally recalled and recognized better in memory tasks, although several theoretical positions and a variety of empirical tasks indicate the importance of verbs to sentences. To try to resolve this paradox, several experiments were designed to explore the efficiency of various sentence elements as cues in recognition memory. Subjects…

These forty conference papers deal with a wide variety of new approaches to the application of developmental theory. The papers represent a cross-section of current research methodology and techniques used to evaluate such traditional Piagetian topics as concrete and formal operations, conservation, classification skills, language development,…

The conjecture was investigated that the intellective load carrying capability for selected intellective functions is identifiable and measurable. Intellective load carrying failure was defined as the point at which a change in transfer function components occurs as a tracking and a scaled intellective function were concomitantly performed. The…

This paper reports further on the study described in SE 019 717. Correlational data relating success on proportionality tasks to understanding of related concepts and processes are presented. The five correlative tests involve (1) reducing fractions, (2) multiplying fractions, (3) facility with fractions, (4) inverse relations, and (5) more…

It is generally assumed that students possess the ability to apply abstract reasoning to content material in a variety of disciplines when they enter college. Yet many college students have not reached the level of formal operations defined by Jean Piaget; thus they experience difficulty in coping with their work. A solution to this dilemma can be…

The Zip Pak for the pre-primer reading level was developed for use with migrant Mexican American children who have reading deficiencies. The area of failure with these children has not been with the visual discrimination involved in decoding, but with the interpretation of the material to be decoded. Therefore, the 5 lessons in this student…

This study compares the effects of Montessori methods of instruction and methods of direct verbal instruction. Montessori methods rely on the ability of the child to learn through physical interaction with inanimate objects and minimize verbal behavior by teacher and student, while the direct verbal method works mainly through language use, both…

The objectives of this study were to determine the strength and importance of the relationships among features of oral and written language proficiency and their accompanying thought processes, and to dimensionalize variables that may be manipulated to assist development of disadvantaged children. Test scores from measures of language/thinking…

The criterion problem in the neoPiagetian cognitive-developmental literature is reviewed. This problem has provoked debate in the context of three empirical questions: concept age norms, concept training effects, and concept invariant sequences. It is argued that only the question of invaniant sequences in same-stage concepts is theoretically…

This paper reviews the literature concerning the development of deductive reasoning, emphasizing the verbal form of the arguments involved in the reasoning. Empirical research is grouped under the heading: assessment studies, critical thinking, instructional studies, and logic and proof. A conceptual framework is developed and a section on errors…

The ability of 120 children (mean ages 6.2, 8.2, 10.1, and 12.3) to perform discrimination learning and subsequent transposition tasks was observed utilizing three experimental conditions (overt-verbal, covert-verbal, and control). The performance of the subjects suggests that the child who is forced to verbalize his conceptual strategies will…

This paper addresses itself to the question of whether the high degree of abstractness in Chomsky's and Halle's analysis of English vowels is justified. Secondarily, two related topics are discussed: (1) limitations on the tongue-height features [+low] and [+high] and (2) the role of rule features in phonological rules. Numerous examples of a more…

This study investigated several questions generated by cueing system research. The cueing system is perceived as a means of directing our categorizing behaviors in the processing and recall of information. Experiments involved a comparison of categorical cueing systems on a given task in relation to two control areas: (1) subjects using a free…

This ten chapter book is designed to provide high school students with an understanding of basic communication processes. The first five chapters include discussions of language development, function, and acquisition in relation to both human and non-human communication. The sixth chapter contains specimen linguistic analyses of speech and…
