Chapter 3 Flashcards
main concepts of cognitive psychology
- information processing depends on mental representations
- mental representations undergo internal transformations
word superior effect
letters are better recognized as part of a word than within a random string of letters
Alzheimer’s disease
a degenerative vascular disorder caused by tangles within neurons and plaque build up in the brain that increases with age
epilepsy
excessive and abnormal patterned behavior in the brain; often causes seizures which are a transient loss of consciousness
double dissociation *
strongest neuropsychological evidence that a patient has a selective deficit in a certain cognitive function; done by studying two patients who have different lesions that affect different areas of the brain
agonist
pharmacological substance that activates a receptor to cause a biological activity
antagonist
pharmacological substance that blocks the activation of a receptor to prevent a biological activity
behavioral genetics
study of how genetic makeup and environment impact behavior
knock out procedure
study method that involves inactivating part of a gene
deep brain stimulation
invasive form of brain stimulation that involves implanting an electrode on the brain
optogenetics *
a protein is encoded in a virus that is selectively given to certain neurons that allows them to be ‘turned on and off’ by different light exposures
transcranial magnetic stimulation *
form of noninvasive neuronal stimulation that involves using a magnetic field to temporarily deactivate neurons
(rTMS) repetitive
(noninvasive) low frequency bursts stimulation over a long period of time- inhibitory effects
cTBS (continual-theta burst stimulation)
high frequency continuous stimulation for a shorter period of time- excitatory effects
ERP (event related potential)
measure of neuron that aligns a trial relative to an event
PET
brain scan that uses radioactive tracer distribution to see brain function
fMRI
noninvasive brain scan that measure Blood Oxygenation Level Dependent signals as an indirect measure of brain activity
connectomes
structural or functional connections within the brain
