2. AO2: energy levels only drop in NREM sleep, not in REM sleep. This discredits which explanation?

  • the energy conservation explanation
  • the foraging requirements explanation
  • the waste of time explanation
  • the predator avoidance explanation

3. AO2: An alternative approach by Horne (1998) combines the evolutionary and restorative explanations. It suggests:

  • There is a core and optional sleep: the core sleep is mainly SWS and is vital for processes to work and optional sleep is mainly REM and is dispensable.
  • There is a core and optional sleep: the core sleep is mainly REM and is vital for processes to work and optional sleep is mainly SWS and is dispensable.

4. AO2: general support for the evolutionary approach comes from who that found mammals with similar genes have similar sleep patterns

  • Capellini (2008)
  • Meddis (1975)
  • Horne (1998)
  • Siegel (2008)

5. AO1: Sleep is a period of inactivity which is important for warm blooded animals who use lots of energy maintaining body temperature and for small mammals with a high metabolic rate.This refers to which evolutionary explanation?

  • Energy conservation
  • Foraging requirements
  • Predator avoidance
  • Waste of Time
