Introduction to Perception
Multiple Choice Quiz
The phenomenon of perception
results in a perfectly accurate representation of the world.
improves the chances for survival.
is an entirely psychological phenomenon.
has evolved only recently.
Perception alters the view of the world by
diminishing irrelevant or redundant information.
ignoring a large amount of potential sensory information.
failing to take into account regularities of matter and energy.
both a and b.
Sensory transduction is the process by which
sensory stimuli are analyzed.
nerve fibers conduct sensory information.
physical energy is converted to biochemical energy.
information from different sensory modalities are compared.
A stimulus is
the physical energy that begins the perceptual process.
the psychological correlate of physical energy.
the manner in which sensory nerve fibers communicate with one another.
another word for a perception.
Psychophysics is the scientific discipline that
relates the activity of sensory nerve fibers to perception.
characterizes the physical nature of sensory stimulation.
compares human perceivers to a computer-generated model.
relates a sensory stimulus to a perceptual event.
Materialism is the philosophical perspective that
perception depends only on the nervous system.
perception begins with physical material.
only your mind exists and all worldly objects are creations of your mind.
the world is exactly how it appears to be.
The purpose of active perception is to
distinguish self-produced patterns of stimulation from externally-produced ones.
guide our sensory sampling based on our physical needs.
eliminate the need to make decisions based on sensory stimulation.
reduce the overall quantity of sensory information.
"Near" senses are distinguished from "far" senses because
some senses require direct contact with the source of stimulation.
information from the "far" senses are more behaviorally relevant.
"near" senses allow more time to consider the behavioral reaction.
"near" senses aren't found in higher species of animal.
A Necker cube helps to demonstrate that
perceptions have qualities not present in the physical stimulus.
interpretations of physical stimuli are stable and dependable.
the physical world is entirely a product of the mind.
changes in appearance are due to changes in the physical stimulus.
Muller's doctrine of specific nerve energies states that
neurons of a given sensory system resonate to a particular physical stimulus.
the nature of a sensation depends on how the sensory fibers were stimulated.
neurons of a given sensory system can only be stimulated by a one type of stimulus energy.
the nature of a sensation depends on which sensory fibers were stimulated.
The phenomenal/naturalistic approach to studying perception is hindered because
it can only be applied to animals in the wild.
of it's heavy reliance on verbal report.
the frequency of individuals with Anton's syndrome make conclusions suspect.
informal approaches have no role to play in the study of perception.
The primary criticism of the experimental approach to studying perception is that
the stimuli that are used cannot be repeated precisely.
it's impossible to compare experimental results between two participants in the study.
the stimuli that are used are not the same as those for which the sensory systems evolved.
the behaviors measured are no more reliable than verbal report.
The lesion technique for studying perception is advantageous because
it is non-invasive (i.e., doesn't harm the participant).
it suggests the anatomical locus of a perceptual function.
there is a one to one relationship between lesions and behavioral deficits
the results of a lesion study are definitive and conclusive.
The primary advantage of both PET and fMRI brain imaging is that
they measure neural activity on a very fine spatial scale.
they directly measure neural activity.
they can relate human brain activity to performance in a perceptual task.
they don't require radioactive labeling agents.
Seeing subjective contours in a Kaniza figure
is a uniquely human trait.
has no physiological basis.
indicates that brain damage has occurred.
suggests that the brain is fabricating a more likely interpretation of the figure.
