Cognition ch 5

by studying the abnormal its possible to

classical neuropsychology favors _____ _____ and cognitive neuropsychology favors ______ ____ _____

in neuropsychology the performance of different patients is combined to yield a group average

in cognitive neuropsychology, the data from different patients are not combined

non-invasive stimulation of the brain caused by a rapidly changing electrical current in a coil held over the scalp

disruption in the blood supply to the brain

over elastic region of artery that is prone to rupture

the basic logic behind the cognitive neuropsychological approach

if the patient performs entirely normally on task b compared to a control group. also could be impaired on both tasks but significantly more on one

if two tasks share the same neural/cognitive resource but one task uses it more, then damage to this resource will affect one task more than the other

one task is performed worse than another because the task is performed sub-optimally (but not because some aspect of the task is compromised)

an example of task demand artefact

in general almost all neuropsychologic studies are aimed at

two single dissociation that have a complementary profile of abilities

difficulties in spelling and writing

a cluster of different symptoms that are believed to be related in some meaningful way

carmazza's assumtions that underpinned almost all neuropsychological studies

the assumption is stated with reference to a lesion within a particular cognitive model and not to a lesion to a particular region of the brain

using observations of brain damaged individuals to inform theories of cognition
