descriptionword/key phraseextra hint
perceptual xperience of one sense evoked by another sense
form, constancy, depth are examples of how we ______ perceptions
number of cones (approx)densely packed in fovea
perceptual process that assembled info into patterns that help us understand the world
process where different groups of cells specialize for different types of analysis and allow for rapid searching
readiness to perceive in a particular manner, based on expectations (e.g. facial features)
processing where individual elements are examined in order to create the whole, the bottom is the stimulus
methods that meausre the strength of a stimulus and the observer's sensitivity to that stimulus
the differences in the retinal images of the two eyes that provides info about depth
photoreceptors that become active only under low-light conditions for night vision
the ability to see fine detail
list an example of a perceptual groupings
an area of the retina that contains neither rods nor cones and therefore has no mechanism to sense lightoptic nerve creates this
aspects of a scene that yield information about depth when viewed with one eye
number of rods (approx)evenly distributed around retina xcept at fovea
an area of the retina where vision is the clearest and there are no rods at all
process where we can perform more than 1 activity at one time, but our attention is a limited resource
descriptionword/key phraseextra hint
simple awareness due to the stimulation of a sense organ
the region of the sensory surface that, when stimulated, causes a change in the firing rate of that neuron
light-sensitiv tissue lining the back of the eyeball
far sighted, image focused behind retina because eyeball too short
the organization, ID and interpretation of a sensation in order to form a mental representation
perceptual process that pays attention to some stimuli and ignores others
sensitivity to prolonged stimulation tends to decline overtime as an organism adapts to current conditions
what takes place when many sensors in the body convert physical signals from the environment into neural signals sent to the CNS
a perceptual principle stating that even as aspects of sensory signals change, perception remains consistenaka recognizing a friend who is not looking directly at you
perceptual process that shows how the brain explains sensations
near sighted, image focused in front of the retina because eyeball too long
the just noticeable difference of a stimulus is a constant proportion despite variations in intensitye.g. JND for weight 2%
photoreceptors that detect color, operate under normal daylight conditions, and allow us to focus on fine detail
the minimal change in a stimulus that can just barely be detected
processing where the whole is used to perceive its elements, the top is the mental set
an observation that the response to a stimulus depends both on a person's sensitivity to the stimulus in the presence of noise and on a person's response critereon
the minimal intensity needed to just barely detect a stimulus
