Document Summary
The last sense to develop is vision. They can learn the sound of the mother"s voice, the cadence of a story, and the sound of the mother"s native language in the womb. Fetus are soothed by familiar things: fetal heart rate decreases when they are told a familiar story. Decasper: tested the preferences of newborns using the rate at which they suckle. Cross-sectional study: comparing similar groups at different ages at the same time. Cohort effect: studying the same age across different areas. Attrition: when participants don"t participate in a second session of a study. Longitudinal studies: data is collected from the same group at different time periods, more likely to show a cause-and-effect relationship. Studying looking time tells us about cognition: the baby has habituated to something, the baby remembers seeing something, the baby is surprised to see something. Babies perceptions and reactions: develop a sense of whether a fall could be dangerous several weeks after they start crawling.
