research has shown that a major reason for poor performance while multitasking is that while multitasking, people
switch their attention rapidly from task to task, so they miss critical information associated with a task that is not receiving their attention

A sound is often detected by one ear more intensely and a fraction of a second earlier than it is detected by the other ear. These cues help individuals determine the
location of the source

feature detectors are neurons that are turned on or off by specific features of visual stimuli like edges and movement. where in the visual system are these feature detectors located?
occipital cortex

absolute threshold
what is the light-sensitive surface of the eye that contains photoreceptors?
The retina is the light-sensitive tissue that lines the inside surface of the eye
which photoreceptors are responsible for color vision?
cones
what are the nerves that carry neural impulses from the eye to the brain? what forms them?

the most common form of color blindness is related to deficiencies in which color system?
red-green
a subliminal stimulus is a stimulus that
falls below the threshold for conscious detection
deven is at a concert when a singer hits a very high note at the end of a song. why is the pitch of the note so high?
frequency is higher
the place in the retina where the optic nerve exists to the brain is called the
blind spot
the fovea has the greatest visual acuity in bright light primarily because the fovea

why do babies turn away in disgust if a bitter substance is placed on their tongue?
they do not have developed taste buds
what is the correct order of information processing in vision?
rods and cones, bipolar cells, ganglion cells, optic nerve
in visual perception, size consistency occurs as an object comes closer to the viewer because the
perceived assistance of the object becomes smaller
When a pair of lights flashing in quick succession seems to an observer to be one light moving from place to place, the effect is referred to as

sensory adaptation
A reason that one typically does not notice a blind spot in the visual field is that
the brain fills in missing information so there is no awareness that the visual field is incomplete

analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
