Q

AO1 Focus

What effect does progesterone have on the lining of the womb?

A

Grows thicker

17
Q

AO1 Focus

If a female does not get pregnant, what happens to the egg?

A

It is absorbed into the body

18
Q

AO1 Focus

What are the main endogenous pacemakers involved in infradian rhythms?

A
  • Pituitary gland
  • Oestrogen and progesterone
19
Q

AO1 Focus

What are some examples of exogenous zeitgebers that can influence the female menstrual cycle?

A
  • Light
  • Stress
  • Pheromones
20
Q

AO1 Focus

How can exogenous zeitgebers affect infradian rhythms?

A

They dysregulate the rhythm

21
Q

AO3 Focus

What was Russel’s procedure?

This would form the first E of your PEEL

A
  • Asked a sample of women to wear cotton pads under their arm
  • Rubbed on the upper lip of 5 sexual inactive women
  • Repeated for 5 months

This would form the first E of your PEEL

22
Q

AO3 Focus

What were Russel’s findings?

This would form the second E of your PEEL

A

4 out of 5 women developed menstrual cycles that synchronised to within one day of the donor cycle

This would form the second E of your PEEL

23
Q

AO3 Focus

What do Russel’s findings show?

This will form part of your Link in your PEEL

A

That infradian rhythms are influenced by exogenous as well as endogenous factors

24
Q

DISCUSSION Focus

What type of experiment was Russel’s study, and what is an issue with this method?

This could act as a counter to Russel’s RTS

A
  • Field experiment
  • Low control over extraneous variables

This could act as a counter to Russel’s RTS

25
Q

DISCUSSION Focus

What is an example of an extraneous variable which Russel did not control?

This could act as a counter to Russel’s RTS

A
  • Light
  • Diet
  • Stress
26
Q

DISCUSSION Focus

How do potential extraneous variables affect Russel’s research?

This could act as a counter to Russel’s RTS

A

Lowers the internal validity

This could act as a counter to Russel’s RTS

27
Q

DISCUSSION Focus

Russel’s research may have extraneous variables.

What does this mean it is difficult to establish cause and effect between?

This could act as a counter to Russel’s RTS

A

Pheromones and mainting an infradian rhythm

This could act as a counter to Russel’s RTS

28
Q

AO3 Focus

What exogenous zeitgeber in infradian rhythms can be explained by evolutionary psychologists?

This would form the P of your PEEL

A

Pheromones

This would form the P of your PEEL

29
Q

AO3 Focus

Why would pheromones’ role in infradian rhythms have been advantageous in our past?

This would form part of the first E of your PEEL

A

Synchronised pregnancies so one mother could take over caring for an orphaned child

This would form part of the first E of your PEEL

30
Q

AO3 Focus

The role of pheromones in infradian rhythms would enhance the chances of what?

This would form part of the second E of your PEEL

31
Q

AO1 Focus

What can cause an infradian rhythm to become dysregulated?

A

Exogenous zeitgebers
