Biological Rhythms - Ultradian Rhythms

Question 1

What are the three AO3 PEELS to evaluate ultradian rhythms?

Answer 1

Strength - prac apps
Strength - scientific methods
Weakness - low eco val

Question 2

P
(prac apps)

Answer 2

Strength - prac apps in und age related changes in sleep

Question 3

E

Answer 3

• this is bc the fact that the growth hormone is produced during stage 4 of sleep
• has been ass w lack of sleep in old age as research has found older ppl experience less stage 4 sleep

Question 4

Answer 4

• as a result of this research, medication and relaxation techniques have been developed to inc stage 4 sleep in older indv
• to prevent some issues ass with old age such as reduced alertness

Question 5

L

Answer 5

therefore research investigating UR i.a.i.p.o.a.p

Question 6

P
(scientific methods)

Answer 6

In addition, a further strength of research into UR is that it uses scientific methods

Question 7

E

Answer 7

this is bc it is based on obj and emp techniques such as EEGs to measure brain activity or controlled lab settings

Question 8

E

Answer 8

• EEGS scientifically measure brain activity throughout 5 stages of sleep to identify length of rhythm
• and how many times rhythm occurs throughout duration of sleep, excluding extraneous variables such as noise and temp

Question 9

L

Answer 9

• this argues this inc overall int val of research investigating UR
• therefore raising psychologys scientific status

Question 10

P
(discussion - low eco val)

Answer 10

However, the research may have low eco val

Question 11

E

Answer 11

this is bc research is conducted in artifical setting of a lab

Question 12

E

Answer 12

so the sleep experienced by ppts may not reflect their genuine sleep patterns due to the unfamiliar surroundings and bc theyre att to electrodes

Question 13

L

Answer 13

• therefore this may alter the length of the UR, making it difficult to gen findings to exp how UR work in rl
