Ch.3 - Recognising Objects Flashcards
The individual
Perceives a stimulus
Senses are often
Incomplete
Different areas of a brain
Process a stimulus and interact with each other - parallel processing
Stimulus recognition can be vastly aided by
Context
Object recognition may begin with
Detecting simple features
After detecting simple features,
Separate mechanisms put features together (assembling objects)
Object components are identified by
Detectors
Detectors reach their threshold in preference to a stimulus, then
Pass the signal onto other sections of the brain
Detectors are no just neurons or groups of neurons, they’re likely
Complex assemblies of neural tissue
Visual language detectors can be
Letter, groups of letters, words…
The advantage of parallel processing of detector signals is
Speed
Different objects can be perceived
Differently
