Abstract
We evaluated in patients with temporal lobe epilepsy (TLE) and healthy volunteers whether list-learning tests of episodic verbal/figural mem ory and subjective self-reports reliably indicate ''Memory in Reality' ' (MIR). MIR was assessed by the incidental memory of the neuropsychol ogical test event one week after testing. Subjective Memory was assess ed by a questionnaire (SMQ). Patients achieved poorer results than con trols in all measures of memory. Correlation and multiple regression a nalysis indicates that list-learning is highly predictive regarding pe rformance in MIR. MIR predominantly relied on verbal memory in patient s and on visual/figural memory in controls. Subjective memory differen tiated patients and controls but it correlated to MIR only in subjects with unimpaired memory. In conclusion, the data indicate a high ecolo gical validity of list-learning paradigms and they seriously question the diagnostic Value of self-reported memory. They also indicate that incidentally acquired knowledge might be differentially represented in patients with a memory disorder and healthy persons.
