In a previous study, we established that compared to a written case, a video case enhances observable cognitive processes in the verbal interaction in a postgraduate problem-based learning format. In a new study we examined non-observable cognitive processes using a stimulated recall procedure alongside a reanalysis of the data from the first…

Discusses the positive aspects of verbalizing ideas in order to provide a frame of reference which serves to clarify the concept. (Author/HV)

Introduces a systematic methodology for the analysis of covert or latent group talk, along with a set of operational procedures of validation. The methodology is related to analogical reasoning. (RC)

Takes an in-depth look at the probabilistic nature of human communication, i.e, the misinterpretation of the language-producer message by the language comprehender. Reviews the psycho-linguistic, linguistic and philosophical literature dealing with this aspect of language and demonstrates that this misinterpretation is related to a basic process…

Some psychological issues of implication and inference were discussed and dealt with from a theoretical standpoint in an attempt to put clearly into perspective the authors' conceptions of the direction that further research in this area can take to (a) contribute to the understanding of inference and implication in relation to the total message…

Concept labeling and use of complex solutions is facilitated by instructions to verbalize concurrently with initial stimulus presentation. Older subjects who delay verbalization until after task completion are less effective in using relevant stimulus dimensions for solution and more closely approximate the performance of younger concurrent…

This paper examines language in a factory setting and focuses on: (1) identical terms which workers use in different contexts, (2) terms that are discarded or changed, (3) different terms that express opposite units in a conceptual category but are labels for identical objects, and (4) terms which represent finer discriminations within conceptual…

Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)

Three extrinsic factors were manipulated in a problem-solving task performed by 80 ten-year-old children of I Q 90-110. The factors were: the presence or absence of the name of the concept given in feedback, specific instructions, and whether the child was allowed to verbalize. The task was a modification of Vygotsky's experiment on concept…

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…

Four studies tested the hypothesis that collection structures are easier than classes in numerical reasoning tasks. With perceptual input constant, the collection labels in contrast to the class labels promoted children's insight into certain numerical principles and facilitated the use of these principles in a variety of numerical tasks.…

A constructivist analysis of the concepts of communication and environment may go against the traditional ideas of realists. Both concepts are treated as subjective constructs of a cognizing agent. It is held that the basis of the constructivist theory of knowing as the idea that knowledge is a mapping of ways of acting and thinking and the result…

The report documents performance on a 24-month R&D effort oriented toward the development of a computerized model for machine translation of natural languages. The model is built around a set of procedures called verbalization, intended to stimulate the processes employed by a speaker or writer in turning stored information into words.…

To investigate whether problem-based learning leads to conceptual change, the cognitive and metacognitive processes of a group of medical students were studied during the problem analysis phase, and their verbal communication and thinking processes were analyzed. Stimulated recall of the thinking process during the discussion detected a conceptual…

RESEARCH AND EXPERIENCE SHOW THAT FILM IS MORE EFFECTIVE IN FACTUAL LEARNING AND IN PERCEPTUAL MOTOR LEARNING THAN IN TEACHING RATIONAL ACTIVITIES. LANGUAGE AND FILM HAVE DIFFERENT STRUCTURES WHICH DETERMINE THEIR FUNCTIONS IN INSTRUCTIONAL SETTINGS. ESSENTIALLY, PICTURES ARE INDUCTIVE WHILE LANGUAGE IS DEDUCTIVE. LANGUAGE IS CAPABLE OF NUMBERLESS…
