Evaluation of infradian and ultradian rhythms
Cards in this deck (5)
- 1EVALUATION OF INFRADIAN AND ULTRADIAN RHYTHMS: (Evolutionary basis?)STRENGTH AND WEAKNESS:
STRENGTH: Menstrual cycle has evolutionary basis - menstrual synchrony in our ancestors = falling pregnant at similar times + sharing childcare
WEAKNESS: Schank questions validity - too many females cycling together may lead to competition of males = avoidance of synchrony would be naturally selected - 2EVALUATION OF INFRADIAN AND ULTRADIAN RHYTHMS: (Methodology?)WEAKNESS: Methological limitations in synchronisation studies
- Argue there are many factors that affects changes in cycles - stress, diet, exercise (confounding variables)
- So patterns in McClintocks study happened by chance
- Research typically involves small samples - 3EVALUATION OF INFRADIAN AND ULTRADIAN RHYTHMS: (Evidence supporting sleep stages?)STRENGTH: Evidence supports idea of distinct stages of sleep
- Dement and Kleitman
- Monitored sleep patterns of 9 adults - controlled effects of caffeine and alcohol
- REM linked to dreaming, brain activity varied depending on how vivid the dreams were
- Waking during REM = accurate recall of dream
- REM important component - 4EVALUATION OF INFRADIAN AND ULTRADIAN RHYTHMS: (Animal studies?)WEAKNESS:
Role of pheromones found mainly in animals sexual selection
Just speculation of humans
- Cannot be generalised to humans because we have different biology to animals - 5EVALUATION OF INFRADIAN AND ULTRADIAN RHYTHMS: (Practical application?)STRENGTH: Practical application of SAD
- Effective treatment for SAD is phototherapy - light box that simulate strong light in the evening and morning
- Thought to reset melatonin levels in people with SAD
- EASTMAN ET AL: Relieves symptoms in up to 60% of sufferers
