Abstract

Developmental dyscalculia (DD) is a number processing and calculation disorder that has been identified in a similar fashion to other specific learning disorders. That is, the diagnosis is made when the individual’s achievement or ability in arithmetic is significantly below that expected for age, schooling, and level of intelligence. This disorder is conceptualized as a hereditary disorder, being present from early childhood, and is not the result of poor or inappropriate schooling, cultural factors or medical conditions (American Psychiatric Association, 2000; WHO, 1996), although these latter conditions can aggravate any learning disability. Although this widely accepted definition appears plausible, findings from recent years require reconsideration firstly of the way DD is defined and secondly of diagnostic criteria.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
