| Frage | Antworten |
| Biological Rhythms and Behaviour: Objectives | - Identify different approaches to concepts of consciousness - Provide biological evidence for the source of sleep/ wake cycles - Influence of bio. rhythms on psych. states & activity - Why sleep is important - DIMS & DOES of sleep - Role of Psychology in improving sleep |
| Levels of Consciousness | Unconscious Pre-conscious Conscious |
| Biological Rhythms | Circardian Rhythms: Cycles that take 24Hrs to complete, such as sleep/ wake cycle. Affected by dark/light cues Infradian Rhythms: Can take less than 1 day - menstrual cycle of ovulating mammals Ultradian Rhythms: Cycles that can take more than 1 day, such as hunger cycle Disruption of these cycles can causes stress to the body as the body has to readjust to a new pattern |
| The Internal Clock (Circadian) | Suprachiasmic Nucleus: in the cytoplasm show fluctuations in activity (depending on previous day-night cycle). Transplants of the SCN into another animal 'entrain' the rhythm in the transplanted animal. The SCN control the natural rhythm |
| Evidence of Biological Rhythms | Volunteers were put into a 'free-running' condition (where there were no light or dark cues). Wherein they adopted a natural rhythm (SCN) which lasts about 25 Hrs. The Circadian cycles are desynchronised under these conditions. Body clocks are 'reset' within a few days once put back to normal conditions. |
| Influence of biological rhythms on psychological states and activity | Work Hours - night shifts (bad sleep patterns) Jet Lag |
| REM Vs NonREM | REM : NonREM Heart Rate - Slow Decline : variable with high bursts Respiration - Slow : V with high bursts Thermoregulation - maintained : inpaired Blood Flow - Reduced : High Growth Hormone - Fast : Slow |
| Biological Functions of Sleep | Energy Conservation Predator avoidance Body restoration Possible learning and memory benefits |
| DIMS (Disorders of initiating and maintaining sleep) | Insomnia Situational Insomnia (relating to acute stress, life events) Techniques to deal with DIMS - Biofeedback, meditation, self-hypnosis, bedtime relaxation Sleep Medication - (problems include addiction Sleep Apnea - caused by obesity, snoring, high blood pressure |
| DOES (disorders of excessive somnolence) | Narcolepsy Cataplexy Sleep Paralasis Hypnagogic Hallucinations |
| Psychology and Improving Sleep | Education Relaxation Therapy Cognition Medication Withdrawal Behavioural |
