PSY270H5 Lecture Notes - Lecture 8: Mental Rotation, Hierarchical Organization, Essentialism
Document Summary
Exemplar-based approach of categorization: according to this approach, a category is not represented by a single average item. Instead when you think of category, it is represented by all the examples you have encountered before: exemplar based we have a lot of examples. Specificity of the object is lost as you go up. Studies have found that certain object categories activate a specific part of the brain. Ffa is a part of the brain that gets really excited when it sees a face. If you lose that specific area, you lose the ability to recognize that category: each category uses a separate network in the brain to represent a category. Mental imagery: being able to see something without the stimuli, mental imagery: experiencing a sensory impression in the absence of a sensory input. Mental imagery: mental rotation: when you have to mentally move something, does it do the same thing in the brain when you actually move something.
