Theories Flashcards
HM
He had a type of amnesia which meant he could not create any new memories but remembered old ones he could still function and his IQ was higher ⭐️tests showed his episodic was damaged but able to draw the star
Phineas gauge
Metal pole went though his frontal lobe causing him to change his personality
Localisation doesn’t take into account individual differences hertsey found that women have larger broncas areas
Benefits for playing Mario kart for 2 months
Kuhn et al playing at least 30 mins a day increase in key areas like the hippocampus for working memory
Sperrys split brain research
Pots gazed at fixed point in the centre of the screen and visual stimuli was presented to the right or left of the screen very quickly words going to the left hemisphere didn’t process but ppts could physically draw them shows left hemisphere is responsible for langue
What did the picture face test show
Right hemisphere is responsible for visual spatial tasks
Evaluate the split brain research
Small sampling
And brains could be affected by the services
Standized procedures which means that the study is replicable
Danieli
Italian boy who had most of his left hemisphere removed found that his right hemisphere took over to help him with language and speech
What is the role of endogenous pacemakers in regulating circadian rhythms?
They help regulate the sleep/wake cycle
Endogenous pacemakers (EPs) are internal biological clocks that manage circadian rhythms, such as sleep patterns.
What did Siffre’s case study in 1972 demonstrate about sleep/wake cycles?
His body settled into a regular pattern of about 25-30 hours
Siffre spent 6 months in an underground cave without natural light, leading to a ‘free run’ away from environmental zeitgebers (EZs).
What is a key finding from Siffre’s underground cave study?
The internal body clock regulated the sleep/wake cycle without external zeitgebers
This suggests that EPs play a significant role in maintaining circadian rhythms.
What limitation is associated with case study evidence in evaluating the role of EPs?
Case studies may not represent the experiences of others
Siffre’s unique adjustments and personal circumstances may differ from those of other individuals in similar situations.
How long did Siffre spend in the underground cave?
6 months
This extended period without natural light provided insight into the body’s internal regulation of time.
Fill in the blank: Siffre’s body settled into a cycle of about _______ hours.
25-30 hours
True or False: The study of Siffre indicates that environmental zeitgebers are the sole factor in regulating the sleep/wake cycle.
False
The study suggests that both EPs and EZs contribute to the regulation of circadian rhythms.
What does EP stand for in the context of circadian rhythms?
Endogenous pacemakers
What does EZ stand for in the context of circadian rhythms?
Environmental zeitgebers
