Campbell, Jamie I. D.; Thompson, Valerie A. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2012
Retrieval-induced forgetting (RIF) is a widely studied phenomenon of human memory, but RIF of arithmetic facts remains relatively unexplored. In 2 experiments, we investigated RIF of simple addition facts (2 + 3 = 5) from practice of their multiplication counterparts (2 x 3 = 6). In both experiments, robust RIF expressed in response times occurred…

Stazyk, Edmund H.; And Others – Journal of Experimental Psychology: Learning, Memory, and Cognition, 1982
Three experiments evaluated performance on a mental multiplication task and the adequacy of several different models of mental addition as extended to multiplication. Results are discussed in terms of a network-retrieval approach to mental arithmetic, the commonalities between addition and multiplication, and rule- versus retrieval-based…

Geary, David C.; And Others – 1985
Simple and complex addition problems were presented for true/false verification to 30 undergraduate students to test a general model for cognitive addition. Problems were presented on a microcomputer, with reaction time (RT) and response accuracy recorded. Models for addition were fit to average RT data using multiple regression techniques. These…

Ashcraft, Mark H.; And Others – 1980
Research on the structures and processes involved in simple mental arithmetic is reviewed. Results suggest that mental arithmetic is a memory retrieval phenomenon, which develops with the experiences of elementary school and can be understood in general as retrieval from organized network representations. Simple mental addition with basic facts…

Khoury, Helen Adi; Behr, Merlyn – Journal for Research in Mathematics Education, 1982
Investigated the effects of individual difference variables of field dependence/independence and spatial visualization ability on the performance of college students in three modes. The extent to which four variables account for variability in retention test performance on certain tasks was also viewed. (MP)

Ashcraft, Mark H.; And Others – 1981
Students in grades 1, 3, 4, 5, 6, and college were timed as they produced the answers to simple addition problems or verified a given problem as true or false. First graders clearly relied on a counting process for their performance, as advanced by the Groen and Parkman "min" (for minimum addend) model. Third grade appears to be a…

Kaye, Daniel B.; And Others – 1981
This investigation capitalizes upon the information processing models that depend upon measurement of latency of response to a mathematical problem and the decomposition of reaction time (RT). Simple two term addition problems were presented with possible solutions for true-false verification, and accuracy and RT to response were recorded. Total…
