Sensations and Perceptions Flashcards
What is the smell sensory system?
olfactory
What is the touch sensory system?
somatosensory
what is the taste sensory system?
gustatory
What is the hearing sensory system?
auditory
what is the sight sensory system
visual
Cells that collect information from the envrionment
sensory receptor cells
the process of converting information to neural impulses
sensory transduction
What is the detection limit
threshold
What is the minimum detection limit
absolute threshold
What is the minimum difference in stimuli to notice the difference
difference threshold
What is noise?
the extraneous information that interferes with a signal
What is signal detection theory?
the response to a signal depends on an the ability to differentiate between signals and noise
What is sensory adaptation?
How our response decreases to stimuli the longer we are exposed to it.
Bottom-up processing
physical stimuli that is translated into neural impulses
Top-down processing
taking known information and applying it to the stimuli
Perceptual set
external influences that change perception
Treisman’s theory
The more different the features in a set are the longer it takes to see the differences
Recongition-by-components
the more geons the easier to recognize the object
