Test 2 random tid bits Flashcards
(21 cards)
Posner task
(attention)
to study top-down processing (have true and false cues, measure time it takes to respond)
- think paying attention to woman talking in front of you
attentional capture
(attention)
to study bottom-up processing (have distractors)
- think sister tapping you on the shoulder
contingent capture
(attention)
to study bottom-up and top-down processing
- think sister tapping you on the shoulder then responding to exogenous cue with endogenous search task
representational model
(attention)
a model of explanation for hemispatial neglect, it says that R temporal lobe is contralateral and ipsilateral and L temporal lobe is contralateral, so when damage to R lobe, have difficulty with left visual field
attentional bias model
(attention)
a model of explanation for hemispatial neglect, it says that R and left temporal lobes are both contralateral, but L is more so than R and they compete for resources, so when damage to R lobe, have difficulty in L visual field
guided search model
(attention)
a way to search visual field for task, results in activation map
rapid serial visual processing paradigm
(attention)
a way to measure our attentional load, when we respond to one cue, our ability to respond to a secondary aspect that captures our attention is diminished, demonstrating the attentional blink
pop-out and conjunction search
(attention)
this study is to measure how quickly we can identify our attentional goal in our sensory field. this is made more difficult with salient stimuli (ex. stroop task) and the more attentional resources needed to complete a task, the less likely there are spare resources to attend to anything else
HM
Lesion: bilateral medial temporal lobe
Symptoms: anterograde amnesia (couldn’t make new declarative memory), intact WM, can make new nondeclarative memories
Evidence of: MTL separate from WM and non-declarative memory system, episodic memory theory (relies on MTL)
KF
Lesion: L temporo-parietal cortex
Symptoms: impaired WM, intact declarative memory
Evidence of: SM and declarative memories as a separate system
MS
lesion: R occiptal cortex
Symptoms: impaired perceptual priming, intact explicit recognition (about memory not perception)
Evidence of: involvement of visuo-sensory areas in perceptual priming
KC
lesion: MTL damage (kids w hypoxia, damaged HC)
Symptoms: no episodic memories at all, intact semantic memories
Evidence of: relevance of MTL to episodic memory but separation of semantic memories, episodic memory theory
Standard consolidation theory
(Memory)
memory consolidation and encoding occurs initially in the HC, then to the associative cortices, so HC is just redundant and unecessary
Multiple trace theory
(memory)
episodic memory is all stored in HC, but semantic is elsewhere
Cognitive map theory
(memory)
says that the utility of the MTL is that spatial memories are stored in grid cells in the entirhinal cortex, then transferred to the HC
relational memory theory
(memory)
takes cognitive map theory further and extends to any relations, not just spatial
episodic memory theory
(memory)
says that all episodic memories are encoded by the HC, but not semantic (evidence from KC and HM, who have intact semantic but not episodic memory and disrupted HC)
declarative memory theory
(memory)
all declarative memories are encoded by the MTL (ofc episodic are the first to go bc they’re more repeatedly encoded
3 process model
(memory)
integrates many theories, says perirhinal ‘what’ stream and the parahippocampal; ‘where’ stream integrates info in the HC
top down processing
(memory)
for familiarity bc requires more work
dorsal parietal region
bottom up processing
(memory)
for recollection bc requires less work
