Memory and perceptual changes during pregnancy
This article examines changes in memory and perception during pregnancy. Pregnant women often have difficulty with multi-tasking and remembering future activities; however, they show improvement in memory for faces and recognition of emotional changes, particularly in men. They tend to have an increased sensitivity to odors, many of which are perceived as unpleasant. Perceptions of taste alter throughout the pregnancy, with cravings for sweet foods in the second trimester and for salt in the third; sour tends to be preferred throughout the pregnancy. Childbirth educators can help to reassure students that such changes are normal and will resolve after childbirth.
