COGNITION: MENTAL IMAGERY | CONCEPT AND PROTOTYPE Flashcards
instinctual (System 1) and deliberate (System 2)
two types of thinking
involves making quick decisions and using cognitive shortcuts, is guided by our innate abilities and personal experiences
System 1
which is relatively slow, analytical, and rule-based, is dependent more on our formal educational experiences

participants were asked to push a button when they had imagined themselves moving from one place on the island to another. As the graph below the picture shows, participants took longer times to complete the task when the locations on the image were farther apart.
Kosslyn’s Fictional Island 1978
researchers have been able to see the overlap that occurs in brain areas activated during visual mental imagery tasks as compared to actual tasks involving visual perception
functional magnetic resonance imagery (fMRI)
frontal cortex
cognitive control
temporal lobes
memory
parietal lobes
attention and spatial memory
occipital lobes
visual processing
are only one form of mental representation
Mental images
Another aspect of thought
processes, ideas that represent a class or category of objects, events, or activities.
Concepts
use to think about objects or events without having to think about all the specific examples of the category.
