Habituation
Repeated stimulus produces smaller response when presented repeatedly
Can recover response with disabituation
Experiment with fetuses: found that kicking reduced as they habituated to a vibroacoustic stimulation (VAS). Habituated faster when presented 10 mins later.
Fetal Learning
We can quantify this through:
- Changes in fetal behavior/response
- Behavior after birth
Experiments
- Prenatal experience and later taste preferences
Experiment where mother consumed water and carrot juice in different parts of their childs development. (CW, WC, WW). Then infant preference tests at time of weaning where administered.
- Found that children exposed to carrots (C groups) had substantially less of a negative face response when presented carrot flavored cereal.
- Memory for prenatal auditory experience
Mothers read the same story out loud every day for the last 6 weeks of pregnancy.
Baseline sucking rate was recorded. Then when infants increased/decreased their sucking rate, they either heard a familiar/different story.
- Infants produced the sucking rate that resulted in hearing the familiar story.
Takeaways
- Sensory systems begin to function during prenatal development
- Fetus can learn and form memories
- At some level, what is learned during the prenatal period is remembered after birth
