The ‘dice’ game: A new test of pragmatic language skills after closed-head injury

Abstract

There are few clinical tools available to assess communication skills following closed-head injury. This paper describes one such task in which the subject is required to explain a board game to a naive listener. The explanation is taped, transcribed and the content is quantified. Reliability studies demonstrated that the test can be consistently scored. A group of 43 normal subjects was investigated, and some variation in peformance according to age and educational background was revealed. A group of 20 brain-injured male adults with executive-type deficits were then compared to a matched subgroup of the controls. The clinical group produced less essential information and relatively more unnecessary information than their non-brain-damaged counterparts. Qualitative features of discourse disorganization were also revealed.
