Thermoreceptor
Info regarding temp is processed by _______ cell in the skin
illusions
Visual__________occur because stimuli in the environment consistently produce errors in our perception
disparity
The difference between the images in the two eyes or the ________ is the binocular cue the brain uses to determine the depth or distance of an object
Weber's law
What law of psycho-physics states that two stimuli must differ by a constant minimum percentage (rather than a constant amount) to be perceived as different?
Sensation is the initial activation of the sense organs
perception is the processing of the information from those organs in the brain
movement
The perception that a stationary object is moving is called apparent__________
Pain
is the sensation that warns us of damage to our bodies
protects the lens of the eye
Cornea does
The smallest change in stimulation needed in order to discriminate one stimulus from another
The difference theshold is
kinesthetic
senses provide informaiton about movement, posture and orientation
Depth
perception is the ability to perceive objects 3-dimensionally
nose
is an active instrument and we actively sniff when we are trying to track the source of an object of interest
perception
the sorting out, interpretation, analysis and integration of stimuli by the sense organs and the brain is called_______
sclera
is the white, outer part of the eye that helps to maintain the shape of the eye and to protect it from injury
Gestalt perspective
includes the principle that the whole is different from the sun of its parts
Cones
are receptor cells contained in the retina and are useful in color perception, particularly in bright light conditions
vestibular
sense provides information about balance and movement
thermoreceptor
information regarding temp is processed by ____________cells in the skin
Visual cortex
processes sensory information from the eyes in the occipital lob of the brain
familiar size, linear perspective, and texure gradient
are monocular cues that help with depth perception
Light
is a form od electromagnetic energy that can be described in terms of wavelengths
Size, shape and color
3 types of perceptual constancy
Sensation, perception
Specialized receptor cells inthe sense organs detect stimuli from the environment. This is called ______________. The brain then gives meaning to the stimuli, which is called ____________
Apparent movement
the perception that a stationary object is moving
pupils
adjust the amount of light reaching the retina
opponent-process
theory of color vision outlines how receptor cells for color vision are linked in pairs
Top-down processing
begins with the higher levels of the brain
bottom-up processing
processing that is initiated by sensory information about the external environment
Shading
is the monocular cue that involves changes in perception due to the position of the light and the position of the viewer
Trichromatic
the presence of "afterimages" cannot be explained by the ________ theory of color vision
Rods
are important in low light
Sensory receptors
take information from the environment, creating local electrical currents. The receptors trigger action potentials in sensory neurons, which carry the information to the central nervous system
trichromatic
theory of color vision outlines three types of cones that work together to form color vision
Warm and cold
are two types of thermoreceptors
Bottom-up
processing that commences with sensory receptors registering environmental information and spending it to the brain for analysis and interpretation is known as
