what happens in the brain when you conjure up a mental image in your mind’s eye
what did O&K test
whether particular regions of extrastriate cortex activated during mental imagery depending on content of image
how did O&K test it
used fMRI -> demonstrated selective activation withing region of cortex specialised for face perception during mental imagery of faces
& done the same for specialised place perception during mental imagery of places
results of O&K
found it’s possible to determine content of single cognitive events from inspection of fMRI data from individual imagery trials
conclusion of O&K
data strengthens the evidence that imagery & perception share common mechanisms & demonstrate that specific brain regions activated during mental imagery depend on the content of the visual image
limitation of O&K
cause & effect
conclusion of HM
brain & behaviour affected
brain = memory
behaviour = seizures stopped
James-Lange theory of emotion proposed
emotions arise as result of physiological response - they encounter stimulus which creates bodily response & brain interprets with a physical reaction - emotion
JLT example
your heart beating rapidly leads yu to realise youre afrid
Cannon counter argument to JLT
wasn’t necessary for feeling of emotions to be based on body
Cannon experiment
cats were induced into sham rage
decerebrated cats retain behvaiourally integrated rage
cannon results
acitivty in thalamus & hypothalamus was responsible for quality of sensations of emotions
JLT limitations
l
diffiuclt to perceive physiological state accurately
