We report a single case study of a brain-damaged patient with impaired arithmetic
performance. Three principal findings are presented: First, in a task involving production of …

Abstract According to LeFevre, Sadesky, and Bisanz (1996), averaging solution latencies in
order to study individuals' arithmetic strategies can result in misleading conclusions …

Unities in the processes involved in solving arithmetic problems of varying operations have
been suggested by studies that have used both factor-analytic and information-processing …

The current study investigated the role of the central executive and the phonological loop in
arithmetic strategies to solve simple addition problems (Experiment 1) and simple …

In recent years, research has focused extensively on the learning, representation, and
processing of mathematical knowledge, and neuropsychological investigations have played …

In this paper, I provide a brief overview of the area of research known as cognitive or mental
arithmetic. The paper focuses especially on the chronometric, reaction time (RT) based …

The area of cognitive arithmetic is concerned with the mental representation of number and
arithmetic, and the processes and procedures that access and use this knowledge. In this …

We compared the working memory requirements of two forms of mental addition: exact
calculation (eg, 63+ 49= 112) and approximation (eg, 63+ 49 is about 110). In two …

In two experiments, obligatory activation of arithmetic facts resulted in interference on a
simple number-matching task. Subjects were required to verify the presence of a probe …

Previous research has demonstrated that working memory plays an important role in
arithmetic. Different arithmetical strategies rely on working memory to different extents—for …
