The present studies were undertaken to examine the effects of manipulating delay-interval task (Study 1) and timing of feedback (Study 2) on acquisition and retention. Participants completed a 100-item cumulative final examination, which included 50 items from each laboratory examination, plus 50 entirely new items. Acquisition and retention were…

Ernst Mach is most closely associated with a positivism that demanded a language of close contact with reality. Mach linked this view with the tradition of the quest for an ideal language in which meaning is a property of a word. Logical positivism and the S-R psychology of the early B. F. Skinner also participated in this ideal-language…

In this article, we explore an interactive learning process in a digital forum that focused on personal cases drawn from student teachers' classroom experience. To this end, we combined theoretical and methodological frameworks of knowledge-based and discourse-analytic perspectives that enabled us to uncover evidence showing what the students may…

The purpose of the present experiment was to study storage properties of dual codes for pictures and words by manipulating instructions and to study retrieval properties by manipulating the representational form of the test items. (Author)

This study was designed to determine whether children 3, 4, and 5 years of age could demonstrate their metaphorical competence equally well in words and in pictures. Previous studies which have investigated young children's metaphorical ability have often encouraged young children to make judgments of similarity which rely almost exclusively on…

Results of a series of studies suggested that excessive early vocal stimulation may be detrimental to infants' cognitive processing, and that optimal development may be associated with a moderate amount of early stimulation. Study 1 involved 59 3-month-old infants and their mothers. Study 2 observed 23 mothers and infants seen 3 months after the…

Semantic theory, its relationship to comprehension, the nature and function of semantic memory, and results of some research on semantic memory and bilinguals are discussed through a review of recent literature. The findings discussed seem to confirm these general observations regarding semantic memory and bilinguals: (1) there is integration and…

Previous studies of the effect of age and modality on digit span task performance have yielded inconsistent results. To eliminate some of the methodological difficulties in prior research, 18 college students and 18 older adults were given the digit span task by means of three different modalities: (1) visual successive; (2) visual simultaneous;…

The role of imagery is assessed in verbal concept identification and evidence is found that some concepts can be coded as images. (Author/AM)

Investigates extent to which perceptual factors of speed and flexibility of closure represent more general processes also operating in cognitive and personality domains by including in a single factor analysis perceptual tests and new tests requiring cognitive abilities resembling closure abilities operating in the perceptual domain.

AN EXPERIMENT TO DETERMINE EFFECTIVENESS OF VISUAL (VI) AND VERBAL (VE) PROGRAMED PRESENTATIONS ALSO VARIED RESPONSE MODE (ACTIVE VERSUS PASSIVE) AND ORDER OF PRESENTATION OF VI AND VE VERSIONS OF A SCIENCE LESSON FOR 200 GRADE 8 STUDENTS, TAUGHT VIA CLOSED CIRCUIT TELEVISION, THE FACTORIAL DESIGN REQUIRED EXPOSURE TO ONE LESSON VERSION, IMMEDIATE…

The auditory/verbal short-term memory of 64 college students was examined across a wide range of retention intervals (5 seconds to 60 seconds). High attention during interpolated processing was ensured by monitoring rehearsal with a combination of methods, and errors were analyzed for evidence of proactive and intra-unit interference. Recall of…

TO DETERMINE THE COMPARATIVE AMOUNT OF LEARNING THAT OCCURRED AND THE AUDIENCE REACTION TO MEETING EFFECTIVENESS, A 20-MINUTE INFORMATIVE SPEECH, "THE WEATHER," WAS PRESENTED WITH VISUAL AIDS TO 23 AND WITHOUT VISUAL AIDS TO 23 INFORMAL, VOLUNTARY, ADULT AUDIENCES. THE AUDIENCES WERE RANDOMLY DIVIDED, AND CONTROLS WERE USED TO ASSURE IDENTICAL…

To develop a coherent description of the knowledge and processes involved in skillful word recognition, a study was devised in which 16 adults participated in four related experiments. The purpose of the first experiment was to examine some basic aspects of the processing of words, pseudowords, and nonwords and to discover basic differences in…
