CLASSIC STUDY: Sperry, hemisphere deconnection + unity in conscious awareness. behaviour = lateralisation of function
CONTEMPORARY STUDY: Casey, behavioural and neural correlates of delay gratification 40 years later, behaviour = delayed gratification
Cerebral cortex
largest part of the brain. the cortex is divided into 4 lobes which is believed to control different functions. frontal lobe = reasoning, planning, memory, parts of speech, movement, emotions + problem solving
The limbic system
a structure in charge of emotion, motivation + memory
To what extent does Casey enhance our understanding of regions of the brain? (5)
Similarities + differences
SIMILARITIES
both have low ecological validity -> lab + task = artificial
both unethical = protection of Ps
DIFFERENCES
Sperry = qualitative, Casey = quantitative
Sperry = follows protection of Ps (doesn't force Ps to get hemisphere deconnection), Casey = breaks protection of Ps
