“…While Lesser (1976) argued that attentional aspects and the sequencing span affected the performance of the speakers with aphasia in the Token Test, other studies have shown that there is a minimal contribution from these factors in the scores (Kreindler, Gheorghita, & Voinescu, 1971). The type of aphasia seems to have no effect on the overall Token Test scores (Mack & Boller, 1979), but the Token Test has been observed to be correlated with the severity of comprehension deficits (Kreindler et al, 1971). The Token Test is also able to distinguish between stroke patients with aphasia, non-aphasic stroke patients (for example, right-hemisphere stroke on right-handed patients), and healthy participants (Swisher & Sarno, 1969;Spellacy & Spreen, 1969).…”
