Abstract

It has been debated whether, word repetition effect (N250r) is affected by selective attention. Therefore, attention was manipulated due to Lavie's perceptual load theory by increasing the number of letter-words (e.g., 3 letter-words; 6 letter-words & 9 letterwords). An immediate (S1-S2) repetition priming paradigm was used, and the participants were instructed to decide whether both S1 & S2 were identical or not. S1 was presented for short time intervals (200 ms), while S2 was presented for long time intervals (1800 ms). Results showed that there is an early repetition effect (N250r) on both hemispheres for 3 letter-words, while this effect appeared in the left hemisphere for 6 letter-words; nevertheless, this effect is vanished for 9 letter-words. These findings suggested that an early repetition effects which occur around 250 ms strongly depend on selective attention.
