Lecture 1 & 2 Flashcards
Response Compression
Intensity increases, the perceived magnitude increases more slowly than the actual increase in intensity. Example: brightness perception.
Response Expansion
Intensity increases, the perceived magnitude increases more quickly than the actual increase in intensity. Example: pain perception
How does context affect perception?
Uh lighting and shit can change what you see like color theory and also like that dress.
How does multimodal processing shape our perception?
this is when you combine senses to change effects like mirror box for phantom pain or playing a sound and only change the mouth movement of a video
distal stimulus
everything in the environment that is available to an observer
proximal stimuli
observer selectively attends to an object and receptors respond to the distal stimulus. Example: images formed on the retina
Principle of Representation
Everything a person perceives is based
not on direct contact with stimuli but rather on representations of stimuli
that are formed on the receptors and the resulting activity in the
person’s nervous system.
Example: we only see stuff because of the stimuli on our retinas
Principle of Transformation
The representations of stimuli in our
environment which we construct are transformed, or changed, between
the original distal stimulus and the eventual perception they give rise to.
Example: distortion and sonic
Sensory receptors
are cells specialized to
respond to environmental energy
Transduction
converts environmental energy into nerve
impulses during receptor processing
Neural processing
involves
changes that occur as signals are
transmitted through the mess of
neurons in our brains
example: brain doing stuff
Bottom-up processing
data-based processing
aka incoming stimuli from senses
Top-down processing
knowledge-based processing
aka processing based on the perceiver’s previous knowledge
oblique effect
our brains love horizontal and vertical stripes but not so much diagonal stripes
