How long does a Circadian Rhythm last for?

Give an example of a circadian rhythm

Define 'Endogenous Pacemaker'

What are examples of endogenous pacemakers?

What is a characteristic of endogenous pacemakers?

Define 'Exogenous Zeitgebers'

What are examples of exogenous zeitgebers?

Explain the Sleep-wake cycle, keeping in mind exogenous zeitgebers and what they do.

Does the sleep-wake cycle work without external cues?

Is the sleep-wake cycle accurate without natural light?

Is there support for the sleep-wake cycle being 'free-running'? If so, what?

What did they find?

Is there support for Siffre?

Is there a validity issue with Siffre's research? If so what is it?

Does Siffre's study have ecological validity?

Is there a limitation for research into the sleep-wake cycle?

What are the two types of individual differences?

Is there support for the importance of external cues?

What did Folkard et al (1985) wonder?

What experiment did Folkard et al (1985) do?

What do the findings suggest?

What is an interesting feature of these experiments?

What is another example of a circadian rhythm?

Explain core body temperature as a circadian rhythm

What are the effects of core body temperature changes?

What study was conducted to investigate the effects of core body temperature on cognitive ability?

What did this study by Folkard conclude about the effects of core body temperature on cognitive ability?

Who else tested the effects of core body temperature on cognitive ability and what did they find?

Is there more evidence that core body temperature effects cognitive ability?

Is there conflicting evidence as to whether body temperature effects cognitive ability?

What could be an explanation for improved cognitive ability with high core body temperature?

Name a third circadian rhythm

explain hormone production as a circadian rhythm

When is cortisol produced?

Which two other hormones have a clear circadian rhythm?

The explanations for the circadian rhythms suggest that the sleep-wake pattern is fixed (determined) by internal mechanisms. Who demonstrates the power of these biologically determined rhythms?

How may this deterministic view be somewhat misleading?

What did Folkard's study show?

Is there a Real World Application from research into circadian rhythms?

What is Chronotheraputics?

How does research into circadian rhythms help us to understand when medications should be taken?

What is a second real world application?
