The '7 Courses Memory Test' has been designed to examine visual-spatial memory components and their interactions in people with acquired brain injury. The test includes recognition parts (Series 1-6) and an incidental spatial recall part (S.7). The first six 'courses' provide a scoring method for the temporal organization of memory items, effect of stimuli frequency, memory inhibition and proactive interference. The test, resembling everyday situations, works with meaningful visual stimuli. The validation process of the test involved the comparison of 86 normal controls and 135 brain injured patients. As a result of both qualitative and quantitative analysis, the two groups are well differentiated by each 'course' of the task. Furthermore, groups with different lateralization and localization can be separated based on the correct answers. (hits), false alarms in S. 1-6 and in spatial S. 7, which is particularly sensible to the damages of the right hemisphere. Patients with right posterior lesion show the worst scores on all seven 'courses' of the task. Specific error types (perseverations, delayed activation, disparity of multiple significance, overestimation of neutral stimuli, lost structure in the spatial task) proved to be characteristic of brain injured patients.
