Endogenous Pacemakers And Exogenous Zeitgebers

Question 1

How do u train babies to sleep?

Answer 1

Through social cues
Infants sleep wake cycle is initially random, but by 6 weeks their circadian rhythm begins and by 16 weeks majority of babies are entrained.
Schedules and mealtimes are determined by the parents , e.g parents are more likely to conform to local times for eating and sleeping, in order to train the infants circadian rhythm

Question 2

Evaluations of endogenous pacemakers and exogenous zeitgebers

Answer 2

+Research support - endogenous pacemakers, Decoursey and Ralph - exogenous zeitgebers, Campbell and Murphy
+Practical application for Jet Lag - conforming to local times
- Animal studies - ecological validity
- Studies only focus on one and not how EZ and EP interact - low validity
