Ashcraft, Mark H. – Mathematical Cognition, 1995

Presents a historical overview and summary of research conducted on simple arithmetic in the past 20 years. Presents two seemingly different directions in current research, one on the role of working memory in mental arithmetic and one on the possible cognitive consequences of mathematics anxiety. Contains 108 references. (MKR)

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…

Ashcraft, Mark H.; Hamann, Mary Sue – 1982

Students in grades 1, 4, 7, and 10 were tested in a two-part investigation of simple and complex mental addition (with college students as a reference point). One session involved a normal reaction time task in which children made true/false judgments about a series of addition examples. The other session involved a verbal protocol interview, the…

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…

Ashcraft, Mark H. – 1983

This report describes a simulation of adults' retrieval of arithmetic facts from a network-based memory representation. The goals of the simulation project are to: demonstrate in specific form the nature of a spreading activation model of mental arithmetic; account for three important reaction time effects observed in laboratory investigations;…

Koshmider, John W.; Ashcraft, Mark H. – Journal of Experimental Child Psychology, 1991

In one experiment, subjects from third grade through college relied on memory retrieval rather than on counting to solve multiplication problems. An effect of confusing problems on error rates and reaction times indicated the activation of related information. In a second experiment, subjects demonstrated automaticity of fact retrieval on simple…

Hamann, Mary Sue; Ashcraft, Mark H. – Journal of Experimental Child Psychology, 1985

First, fourth, seventh, and tenth graders were timed when solving simple and complex addition problems, then were presented similar problems in untimed interviews. Manipulation of confusion between addition and multiplication, where multiplication answers were given to addition problems (3 + 4 = 12) indicated an interrelatedness of these…

Ashcraft, Mark H. – 1985

Described in the context of a computer simulation are highlights of a program of research focusing on the storage of mathematics problem solving information in young children's memory and the development of such knowledge structures in older children. Specifically discussed are the problem size effect, the network nature of the memory…
