Mental Imagery Part 3 Flashcards
What is mental rotation?
Imagining an object in motion and viewing it from different perspectives
In the study of mentally rotating shapes, what rate could they go at per second?
60 degrees per second
On which hemisphere does mental rotation rely on for easy and difficult tasks?
Easy: right hemisphere
Difficult: left hemisphere
ERP study: what did the analysis find about mental rotation and hemispheres for deciding if sides pointed by an arrow would be line up or not if squares folded to make a box?
Carried on equally in both hemispheres
For scanning mental images; when did participants need more time to scan between parts of the map?
More time to scan between parts of the map that were farther apart
What are objective distances?
Preserved in our mental images of perceived scenes
What is a cognitive map?
Information from the environment that is worked over and elaborated into a tentative, cognitive-like map, indicating routes and paths and environmental relationships
Where have cognitive maps been linked with?
Hippocampal activity
What did researchers find about taxi drivers in London?
- They have a larger hippocampus (right posterior) than non-taxi drivers
What is auditory imagery?
Experience of sound in your mind that is not caused by stimulation of the receptive cells in your ears
What is an earworm?
Conscious experience of sound - typically a short piece of catchy music that gets stuck on replay in your head
In the fMRI study for auditory imagery; what happened when the music stopped for familiar and unfamiliar songs?
Familiar: subjects reported playing the rest in their minds, but not for unfamiliar songs
- silent moments of familiar songs activiated same brain regions involved in perception of external auditory sounds
How did brain differences with non-taxi drivers relate to the extent of experience of taxi-drivers?
Increase in size correlated with years of experience
Mental rotation is a function of the right hemisphere. True or false?
False
