This work is an exploration of upper elementary students' sense making around four conventional representations of function: equations with algebraic notation, Cartesian graphs, function tables, and natural language. The cornerstone to the empirical work is a task called the Function Puzzle, where students are given 16 cards representing four…

As part of a search for a unified theory of attention, observers detected letters in streams of digits under conditions of divided or selective attention for a period of 10 hours. The practice effects on the detectability of targets and on the response criteria used by observers were evaluated. (Editor/RK)

Results appear to indicate that the belief systems of the young child about the attributes of a stimulus person can be altered extensively by introducing characteristics completely unrelated to these attributes into the semantic representation of that person. (Authors)

This paper reviewed the original spreading-activation theory developed by M. R. Quillan while trying to correct some common misunderstandings concerning it. It extended the theory in several respects, showed how the extended theory dealt with recent experimental findings, and compared it to the model of Smith, Shoben, and Rips (1974). (Author/RK)

Argues that tables, graphs, and diagrams extend language's power by exploiting the Euclidean possibilities which a text suggests. Notes that graphic display elements form no compatible natural set and that their value and visual elements are decisively disparate. Concludes that graphic displays are unlikely candidates for unitary theoretical…

The Bransfrod and Franks procedure of 1971 for studying the abstraction of linguistic ideas was employed in a sentence memory task but with a recall test substituted for the usual recognition test. (Editor)

The present experiment was designed to test two alternative hypotheses of the roles of input order and semantic structure in determining the effect of blocked presentation and the general facilitation of recall. (Author)

In the present study, the development of the ability to differentiate among various kinds of word meaning was explored with children from the eighth and eleventh grades as subjects. (Editor/RK)

An important issue in encoding theories of memory is the stability of encodings from one stimulus presentation to the next. Article investigate the use of homonyms as an approach to observing the changes in word associations. (Author/RK)

The present research was undertaken in the attempt to gain knowledge about the nature of qualitative changes in vocabulary performance across the major portion of the life span. (Author)

The author presents tables she uses to explain to students the relationships between concepts of symbolic logic, set theory and search strategies. (3 references) (SJ)

Studies the influence of both a syntactic cue (i.e. agent-deletion) and a semantic cue (i.e. non-reversibility) on the evolving comprehension of passive sentences by young children. (Author/RK)

The relation between orientation task and resultant structure of the memory trace was studied using an incidental learning paradigm. Twenty subjects examined 50 pairs for meaningful associations (semantic task), and 20 for rhymes (nonsemantic task). (Editor)

The present study investigated the structure of categories and concepts in psychological research and the nature of mental representations in general. (Author/RK)
