The present study sought to compare adult and infant ERP responses in analogous tests of visual recognition memory. Adults were tested under two test conditions, in which they were given either explicit instructions to respond to a previously-seen stimulus, or no instructions. Testing in both conditions took place after either a 1- or 5-min delay between familiarization and test. Eight-month-old infants were tested under the same 'passive' (no instruction) conditions as adults. ERP morphology differed across age groups. Adults evinced a P300 that was larger under 'active' as compared to 'passive' test conditions, and a late positive slow wave response that was greater to novel than familiar stimuli. There was no evidence in infants of a P300, although infants did demonstrate a late positive slow wave that was greater to familiar than to novel stimuli. Parallels between the infant and adult findings are discussed and in particular, whether the infant slow wave response is the precursor to the adult P300.
