Cognitive Neuropsychology Flashcards
FUNCTIONAL MODULARITY
independent processing units, exhibiting domain specificity (responding to only one class of stimuli) *serial
ANATOMICAL MODULARUTY
each cognitive module is located in one specific brain region
UNIVERSALITY ASSUMPTION
organisation of cognitive functions are very similar across all individuals
SUBTRACTIVITY
brain damage can only disrupt modules or connections (os pacientes nao desenvolvem novos modules para compensar)
Single dissociation
nao indica modularidade
uma tarefa pode simplesmente ser mais difícil do que a outra
Double dissociation
separate modules may underlie each task
diference in processes used on the two tasks
Associations
qdo o paciente is ímpared nas 2 tarefas X e Y.
usado para identificar certas Sindromes
STRENGHS
-double dissociation provides evidence of modularity
-conexoes entre brain areas and cognitive processes to behaviour
-links cognitive psychology and cognitive neurology
LIMITATIONS
-modularity and universality assumptions are too strong
-brain damage often affects several modules
-patients often develop compensatory strategies
-de-emphasises brain plasticity
-individual diferences make it hard to generalise
