Abstract
Recent research has suggested that characteristics of aphasic behaviour may be related to attentionaJ factors rather than linguistic impairments. Aphasic individuals are shown to have difficulty on attention tasks. Inefficient allocation of attention has been proposed to account for aphasic individuals poor performance on such tasks. Attention deficits can affect the accuracy of an individuals comprehension and production skills. Speed of processing influences performance on cognitive tasks and is shown to decrease post- stroke. Assessment of attention in an aphasic individual is essential to determine factors that may be a product of attentional impairment rather than purely linguistic factors. The usefulness of the 'test of everyday attention' (TEA) to measure selective attention deficits in the aphasic population was investigated. Selective attention sub-tests of the map and telephone test were selected. The rating scale of attention (RSA) provided a functional assessment of attention. A 'speed of processing test' was devised and data was collected from 80 non-brain-damaged volunteers for comparison. Language measures were taken to compare performance on the TEA tests to participant's linguistic impairments. Results showed that the TEA selected sub-tests provided a suitable tool for the clinician to measure selective attention deficits in aphasic individuals. However, the telephone test showed a highly significant relationship with linguistic measures suggesting that the map test may prove a more reliable measure of attention. Speed of processing was shown to affect some participant's performance on the TEA sub-tests. It remains unclear as to the extent that visual and motor impairments affected performance.
