Define Cognition
the ability to acquire and process knowledge about the world
Cognition includes
attention, memory, ad executive function
What are the 5 types of attention
orientation
sustained attention
selective attention
alternating attention
divided attention
Describe the dorsal/ posterior attention system
basic orientation to sensory stimuli
alert warning
always on
Describe the ventral/ anterior attention system
sustained attention
selective attention
activated based on intrinsic need
What are the 5 types of memory
short term
long term
working
episodic
procedural
Describe short term memory
temporary storage of memory
e.g. story retell
Describe long term memory
permanent storage of a memory with unlimited capacity
e.g your name, memorable events
Describe working memory
a subset of short term memory
temporary
finite storage for immediate processing and manipulation
e.g. number backwards
Describe episodic memory
recall of specific experienced events
e.g recalling dinner with friends last night
Describe procedural memory
memory sequence of actions to complete tasks
e.g. brushing, dressing
e.g. piano, articulation and grammar, driving
Encoding
initial processing of info
thalamus/ frontal lobe
storage
transfer of info temporarily for storage or access
hippocampus/ bilateral medial temporal lobes
retrieval
activating existing memory traces, strategy for retrieval, initiating for retrieval, accuracy for retrieval
frontal lobe
Describe anterograde amnesia
loss of memory for events occurring after injury
-learning difficulties
Describe retrograde amnesia
loss of memory for events prior to injury
-usually temporary
