研究了气味引起白化病大鼠第一次乳头附着的条件。在实验I中，大鼠出生前和出生后立即暴露于柠檬醛（一种柠檬气味），当乳头被柠檬醛熏过时，哺乳麻醉的临产母鼠的洗过的乳头。此外，这些大鼠未对这些母鼠的正常、未清洗乳头进行染色。在实验II中，大鼠暴露于柠檬醛，（a）在子宫内，（B）出生后立即，（c）出生前和出生后，或（d）根本不暴露。只有组（c）中的大鼠贴附于清洗过的柠檬醛味乳头，并且不贴附于对照大鼠中引起哺乳的正常未清洗乳头。这些发现表明，产前和产后的事件可以决定哪些嗅觉刺激引起新生大鼠的第一乳头附着。
Conditions under which an odor could elicit the 1st nipple attachment in albino rats were investigated. In Experiment I rats exposed prenatally and immediately after birth to citral, a lemon scent, suckled the washed nipples of an anesthetized, parturient dam when the nipples had been scented with citral. Moreover, these rats did not suckle the normal, unwashed nipples of these dams. In Experiment II rats were exposed to citral either (a)in utero, (b) immediately after birth, (c) both pre‐ and post‐natally, or (d) not at all. Only rats in Group (c) attached to washed, citral‐scented nipples and did not suckle the normal unwashed nipples that elicited suckling in control rats. These findings suggest that prenatal and postnatal events can determine which olfactory stimuli elicit the newborn rat's 1st nipple attachment.
