Abstract: | Human neonates were exposed to an artificial odorant for 22h within the first two days after birth. When tested on days1618 postpartum, these infants displayed preferentialorientation to the exposure odor when paired with a novel odorant.The effects of early mere exposure on the stimulus propertiesof odors can therefore endure over a two-week interval, indicatingthat infants retain a memory trace of the exposure odor throughoutthat time period. |
