Memory disorders as a function of traumatic brain injury. Word completion, recall of words and actions.
The memory performance of a group with traumatic brain injury and a matched control group was assessed using the following methods (a) word completion, (b) immediate free, final free and final cued recall of words and (c) immediate free and final free recall of subject-performed tasks (SPTs) and SPTs without motor action (SPTs-WA). The brain-injured (BI) group was significantly inferior relative to the control group in all recall tests except immediate free recall of words. No difference was revealed in the word completion test. The BI-group benefitted less by cues presented either at retrieval (final cued recall of words) or at the time of encoding already built-in in the stimulus (SPTs and SPTs-WA). The results were discussed in terms of the neuropathological background of the patients in the BI-group suggesting that frontal dysfunction could play a critical role. When comparing the tests within the BI-group, however, the performance was better when cues were present and especially so for long-term memory. Motor activity also facilitated long-term memory. Finally, an attempt was made to specify conditions for guidance in the construction of training programmes.
