    Event Related Potentials and Recognition Memory within the "Levels of Processing" Framework

    Event-related potentials (ERPs) were recorded from nine subjects during an incidental memory paradigm. During the study phase subjects were engaged in two tasks requiring semantic and rhyming decisions. During the test phase, subjects were required to decide on each of 320 trials if the word was 'new' (never before presented) or 'old' (seen previously). Results showed that semantic old words were more often recognized than rhyming ones. ERPs to new words were more negative than ERPs to old words in the 400-800 latency range. ERPs to semantic old words were more positive than ERPs to rhyming ones in the same latency range. The difference between ERPs to semantic and rhyming old words confirms a relationship between ERPs and memory

    Event-Related Potentials and Recognition Memory: The Effect of Word Imagery Value

    Event-related potentials (ERPs) were recorded from 11 healthy Ss during a recognition memory task. Ss were auditorily presented with 160 target words and, after about 10 min, they were engaged in a recognition task. Ss were required to determine on each of 320 trials if the word was never before presented or heard previously. 160 stimuli (80 target and 80 non-target) were high imagery words and the remaining 160 stimuli were low imagery words. Results confirm the hypothesis that negative components as N400 could reflect processes occurring during the memory retrieval of item
