In this article, we present data from two brain-damaged patients with calculation impairments
in support of claims about the cognitive mechanisms underlying simple arithmetic …

This article presents results from multiple single-case studies of brain-damaged patients with
impairments in retrieval of arithmetic facts (ie,“table” facts such as 8× 7= 56). The results …

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 …

Retrieval of basic arithmetic facts is a central aspect of almost any arithmetic performance.
Furthermore, the arithmetic facts provide an opportunity to study memory processes in the …

A patient is described who is affected by an inability to recall and use 'arithmetical facts' of
one-digit multiplications and divisions. This loss contrasts with the preservation of a wide set …

In this article we explore how arithmetic table facts (eg, 6× 9= 54) are stored in memory and
evaluate the possibility that arithmetic facts are exclusively stored in a phonological or sound …

We report here the case of a patient (BB), suffering from a precocious evolving dementia
with impaired arithmetic performance, who showed specific and theoretical pertinent …

In the present review we will deal with the following questions: What are arithmetic facts?
How are they related to other cognitive functions? What are characteristic features of fact …

This article presents a framework for the cognitive analysis of number processing and
calculation. Within this framework the primary objective is the development of a model that is …

Two experiments tested the hypothesis that simple arithmetic requires working memory
resources. Subjects were presented with a simple verification task (eg 8+ 4= 12. True …
