chapters 5-10 Flashcards
When an infant exhibits dishabituation, the researcher concludes that the
infant can tell the difference
the ability to perceive a rod as being continuous behind an occluding block
can be accomplished by three-year-olds
her increased gaze is a reflection of a
scene schema in action
land and hayhoe (2001) found that ______ are most important
the task demands
parkhurst et al. (2002) showed that observers make initial fixations in a visual scene based on
stimulus saliency
the eye movements that occur as the observer shifts his/her gaze are called
saccades
according to the FIT features of an object are initially processed in the
pre attentive stage
________ is when a stimulus that is not attended is not perceived
inattentional blindness
the incidence of change blindness _____ when a cue is added to a scene
decreases
optic flow neurons have been found in the monkey’s
medical superior temporal (MST) area
the neurons that signal the monkey’s intention to grab an object are mostly found in the
parietal reach region (PRR)
MST neurons that respond to flow
can be selective to outward-expanding or circular motions
according to land and lee, drivers look
straight ahead, but not directly at the focus of expansion
mirror neurons in the monkey fire
when the monkey sees the experimenter grasp a piece of food, and when the monkey also grasps the food
if you close both of your eyes while standing on one foot,
you lose your balance more quickly than if your eyes are closed
when expert gymnasts close their eyes while performing a somersalt, they perform
more poorly
M.P, a person with brain damage that resulted in the inability to name objects, could
identify objects more accurately when given the function of the object
information that remains constant even though the observer is moving is called
optic flow
bats are able to determine depth by using
echolocation
an insect is mostly likely to use ____ to perceive depth
movement parallax
the ability to use binocular disparity as a depth cue
can be tested using random dot stereogram
motion parallax
is widely used to create depth in cartoons and videogames
stereoscopic depth perception
is defined as depth perception created by input from both eyes
the imaginery plane in which all objects project to corresponding points in the left and right retina is
the haropter
individuals suffering from “walleye” have difficulty with depth perception because
the visual system suppresses vision in one eye in order to avoid having the experience of double vision
of the oculomotor depth cues, convergence is ______ than accommodation
more effective
__________ is the difference in the images in the two eyes; _____ is the impression of depth that results from this info
binocular disparity; stereopsis
__________ is a term used to describe conditions in which movements between the two eyes are not coordinated
strabismus
When light is mixed it is referred to as _______
an additive color mixture.
Opponent neurons found in the ______ provide physiological support for the opponent-process theory.
both the retina and LGN
Physiological evidence shows that deuteranopes do not have the _____ wavelength cone pigment.
medium
A monochromat experiences
black, white, and grays
stimuli that are physically different, but are perceptually identical, are called
metameters
when paint is mixed in is referred to
a subtractive color mixture
The trichromatic theory of color vision is also known as the _________ theory.
Young-Helmholtz
Adding more white to a color changes the color’s
saturation
By changing _______, we can create about a million (or more) discriminable colors.
saturation, intensity, and wavelength
The reflectance curve is a plot of the light reflected off a surface as a function of
wavelength
