Basics
the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment
What is sensation?
The amount of energy in a wave.
What is intensity?
what we use to measure the intensity of sound
What are decibels?
organized whole
What is gestalt?
the controversial claim that perception can occur apart from sensory input
What is extrasensory perception?
below the absolute threshold for conscious awareness
What is subliminal?
rods, cones, optic nerve
What are the parts of the retina?
The rate of nerve impulses traveling up the auditory nerve matches frequency of tone.
What is frequency theory?
a lab device for testing depth perception in infants and young animals
What is a visual cliff?
the study of paranormal phenomena
What is parapsychology?
One starts at the sensory receptors and works up to higher levels of processing. The other constructs perceptions from sensory inputs by drawing on experience and expectation.
What is the difference between bottom up processing and top down processing?
the processing of many aspects of a problem simultaneously
What is parallel processing?
The maximum number of decibels before it is damaging.
What is 85 decibels?
retinal disparity
What are binocular cues for perceiving depth by computing the distance between 2 images from the eyes?
lip movements - "ba-ba"
audio - "ga-ga"
we hear - "da-da"
What is the McGurk effect?
The minimum difference between 2 stimuli required for detection 50% of the time.
What is the difference threshold?
Face blindness.
What is prosopagnosia?
doesn't explain low pitch
What is a problem with place theory?
types of perceptual constancy
What are size constancy, lightness constancy, and color constancy?
the interaction between hearing and vision
What is the McGurk effect?
The study of relationships between physical characteristics of stimuli and physical experience.
What is psychophysics?
The Young-Helmholtz trichromatic theory.
What is the theory that the retina contains 3 different color receptors?
sound waves travel through the cochlear fluid trigger nerve impulses
What is the function of the cochlea?
The illusion of movement created when 2 or more adjacent lights blink on and off in succession.
What is the phi phenomenon?
What are telepathy, clairvoyance, and precognition?
