lecture 22 Flashcards
learning and memory
explicit memory
facts and events that we recall spontaneously and consciously
episodic memories
autobiographical memory for events as the individual experienced them
semnatic memories
facts and info without an autobiographical connection
implicit memories
motor skills that can be performed automatically
emotional memories include ____
affective properties of the stimulus
long term memory systems
explicit, implicit, emotional
short term memory systems
sensory, motor, cognitive
amnesia
loss of existing memories or inability to form new ones
T/F
amnesia requires an event to cause it
True
anterograde vs retrograde amnesia
anterograde - inability to form new
retrograde - loss of old
retrograde amnesia is ____-dependent, ____ events are more likely to be lost
time, recent
islands of memory
events retained within the period of retrograde amnesia
prospective memory
remembering things you intend to do
destination memory
memory for past interactions, like who you told a story to
childhood amnesia
inability to remember events before 4 years old, and difficulty recalling first 10
theories for infantile amnesia
- developmental changes in cognitive abilities and memory systems in the first decade of life
- the rapid proliferation of new hippocampal neurons early on might disrupt stored memories
fugue state
when an individual loses memory of their personal history
fugue states are often ____ and ____, due to damage where?
sudden, transient, memory systems of the medial temporal lobe
T/F
amnesias can exist for specific categories of items
yes, like human faces, fruits and veggies, animals, or birds, etc
autonoetic awareness of time is what and allows for what
the awareness of the continuum of time from our past to our future, allows mental time travel from our past to present to future
autonoetic awarenss depends on what structures
hippocampus and frontal lobes and uncinate fasciculus
where is the semantic memory active
temporal and frontal lobes distinct from episodic memory, esp left
parts of the ____ stream supports explicit memory
ventral
____ relays info from the prefrontal cortex to the temporal lobe so support what type of memory
thalamic nuclei, explicit memory
the ____ store memories when they are formed, older memories re stored in ____
hippocampus, adjacent cortex
early damage to the hipocampus results in what
big problems with episodic memory, but almost normal semantic memory
the rhinal cortex includes what and is part of what
the perihinal and entorhinal cortices, is part of the pathway for info flowing into hippocampus from the neocortex
medial temporal structures
hippocampus, amygdala, perihinal, entorhinal, and parahippocampal cortices
lesions to the hippocmapus in monkeys showed
impaired use of context, but normal object recognition
lesions to the rhinal cortex in monkeys showed
impaired object recognition
