Abstract
The present paper has four main objectives. First, it proposes a general theoretical orientation of memory functions as a basis for the research to be discussed. This framework is functionalistic/interactionistic in nature, in that memory is seen as an interaction between available cognitive capabilities of the individual and specific demands of the situation in which the individual is to remember a certain set of materials. Secondly, on the basis of this framework certain methodological requirements are discussed. These considerations take into account the need for a proper analysis of the to-be-remembered (TBR) information and those cognitive functions involved in remembering the TBR information presented. Thirdly, a preoperative and postoperative memory test is presented. This was designed on the basis of the theoretical and methodological considerations mentioned. Data from one such ongoing study is presented, taking into account various measures of memory functions; immediate free recall, final free recall, final cued recall, serial recall, final final free recall, short-term memory and long-term memory capacity as measured by the Tulving & Colotla [1] lag measure, primacy, asymptote and recency effects, and semantic memory. Finally, on the basis of the experience from this memory test a few aspects of memory testing in epileptic patients are suggested for future research.
