Ch. 2. Perception Flashcards
Our sensory experience of the world is known as:
perception
The processes by which physical properties are converted to neural signals are:
sensations
What kind of perception refers to the perception of the body through touch and sensing of orientation?
Somatic
What describes why perception cannot typically guarantee a faithful representation of the physical world?
The inverse problem
what sort of processing?
original sensory input transformed in an uninterrupted cascade of transformations feeding forward the information, one transformation following another until the final representation is obtained?
Bottom-up processing
What form of processing suggests that perception is based on our expectations?
Top-down processing
What is the name of the relatively rare condition where the sufferer believes that people, or in some instances things, have been replaced with duplicates?
Capgras syndrome
What states that the preferred organization of a perceptual object or event will be the one which is most probable?
The likelihood principle
A statistical approach to perception is provided by a computational theory called:
Bayesian Decision Theory
The theory of embodied cognition is based on the idea that:
Cognition is about experiences that are tightly linked to action.
What does is mean to say that off-line cognition is body based?
Thought is nearly always grounded in perception and action.
Which are the two main pathways from the primary visual cortex used for further visual processing?
Ventral stream and dorsal stream
Any aspect of an object that is preserved no matter the direction from which we view the object is called:
viewpoint invariant relationship.
What is the condition that occurs in the inferior region of the temporal cortex that selectively impacts the ability to recognize shapes and objects?
Visual agnosia
The 2 main component of Cochlear implants
- microphone, sound processor and transmitter
- electrode for transmit signals to the auditory nerve
