T/F? There is a direct perception/action.
False. There is no direct perception/action since there is internal transformations inherent in processing something before it becomes action.
T/F? Info processing depends on internal representations
True. Inner representations cause and explain behavior. Part of the 2 concepts of cognitive psychology.
T/F? Mental representations undergo transformations.
True.
What are the 4 transformational operations?
- Encode - identify target
- Compare - compare mental rep. with stored memory (see if resembles past experiences)
- Decide - whether target matches memorized items
- Respond
T/F: Word recognition is automatic.
True. “Word superiority effect”
What is phenomenon that people have better recognition of letters presented within word as compared to isolated letters?
Word Superiority Effect. (encode, decide, respond - does not need to compare with mental memory). Word recognition is automatic.
This is when two related mental processes are shown to function independently of each other.
Double dissociation (ex. speech and language comprehension, brain structures that control them independently)
Why can’t we do a double amygdalohippocampectomy?
Lose sense of emotion, can’t process new memories =(
What produces “virtual lesions” disrupting activity in region of brain, can treat depression.
TMS (Transcranial magnetic stimulation)
This can study structure of axon tracts, measure white matter pathways. Also, newest way to analyze brain.
Diffusion Tensor Imaging (DT)
T/F: MRI has higher resolution than CT.
True.
This measures electrical activity of brain, shows internal/external changes.
Electroencephalography (EEG)
This detect changes in blood flow while engaged in task, reveal metabolic changes associated with neural activity.
Functional MRI
Does PTSD cause hippocampal shrinkage, or is it pre-existing condition?
PTSD did not appear to cause hippocampal shrinkage… if you don’t have a robust hippocampal activity… you may experience PTSD easier
Reminders of traumatic experiences activate brain regions that support intense emotion, decrease activation of CNS region involved in sensory input with motor input and modulating arousal, and capacity to communicate experience in words.
PTSD
What is key psychological issue for all organisms?
Control. Opposite is learned helplessness. ex) nursing home study, pick plant and movie night, lived longer.
Key emotional hot spot
Amygdala
Area for speech and key for PTSD
Broca’s
Key to emotional control and attention; DOWN REGULATED in ppl with PTSD, apathy, Alzheimer’s, and schizophrenia
mPFC/ACC (Anterior Cingulate Cortex)
T/F: Theory of Mind is only in the right brain.
False. Bilateral. Related to narrative.
What is related to narrative?
TOM and Interpreter
T/F: Interpreter is only in L brain
False. Bilateral.
What is key to rewards, motor planning, action and execution, dopamine prevalent?
Striatum
T/F: Basal Ganglia is dysregulated with PTSD.
False. Dys-Regulated Striatum found in PTSD.
