PSU Psych 100 Exam 2 questions with
|\ |\ |\ |\ |\ |\ |\
answers
sensation - CORRECT ANSWERS ✔✔the process by which our
|\ |\ |\ |\ |\ |\ |\ |\ |\
sensory receptors and nervous system receive and represent
|\ |\ |\ |\ |\ |\ |\ |\
stimulus energies from our environment
|\ |\ |\ |\
perception - CORRECT ANSWERS ✔✔the process of organizing
|\ |\ |\ |\ |\ |\ |\ |\
and interpreting sensory information, enabling us to recognize
|\ |\ |\ |\ |\ |\ |\ |\
meaningful objects and events |\ |\ |\
bottom-up processing - CORRECT ANSWERS ✔✔analysis that
|\ |\ |\ |\ |\ |\ |\
begins with the sensory receptors and works up to the brain's
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
integration of sensory information |\ |\ |\
top-down processing - CORRECT ANSWERS ✔✔information
|\ |\ |\ |\ |\ |\
processing guided by higher level mental processes, as when we
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
construct perceptions drawing on our experience and
|\ |\ |\ |\ |\ |\ |\
expectations
transduction - CORRECT ANSWERS ✔✔conversion of one form of
|\ |\ |\ |\ |\ |\ |\ |\ |\
energy into another. In sensation, the transforming of stimulus
|\ |\ |\ |\ |\ |\ |\ |\ |\
energies, such as sights, sounds, and smells, into neural impulses
|\ |\ |\ |\ |\ |\ |\ |\ |\
our brain can interpret
|\ |\ |\ |\
,psychophysics - CORRECT ANSWERS ✔✔the study of the |\ |\ |\ |\ |\ |\ |\ |\
relationships between the physical characteristics of stimuli, such|\ |\ |\ |\ |\ |\ |\
as their intensity and our psychological experience of them
|\ |\ |\ |\ |\ |\ |\ |\ |\
absolute threshold - CORRECT ANSWERS ✔✔the minimum
|\ |\ |\ |\ |\ |\ |\
stimulation needed to detect a particular stimulus 50 percent of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the time |\
signal detection theory - CORRECT ANSWERS ✔✔a theory
|\ |\ |\ |\ |\ |\ |\ |\
predicting how and when we detect the presence of a faint
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
stimulus (signal) amid background stimulation (noise). Assumes
|\ |\ |\ |\ |\ |\ |\
there is no single absolute threshold and that detection depends
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
partly on a person's experience, expectations, motivation, and
|\ |\ |\ |\ |\ |\ |\ |\
alertness.
subliminal - CORRECT ANSWERS ✔✔below one's absolute|\ |\ |\ |\ |\ |\ |\
threshold for conscious awareness |\ |\ |\
priming - CORRECT ANSWERS ✔✔the activation, often
|\ |\ |\ |\ |\ |\ |\
unconsciously, of certain associations, thus predisposing one's |\ |\ |\ |\ |\ |\ |\
perception, memory, or response |\ |\ |\
difference threshold - CORRECT ANSWERS ✔✔the minimum
|\ |\ |\ |\ |\ |\ |\
difference between two stimuli required for detection 50 percent
|\ |\ |\ |\ |\ |\ |\ |\ |\
of the time.
|\ |\
Weber's Law - CORRECT ANSWERS ✔✔the principle that, to be
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
perceived as different, two stimuli must differ by a given
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
percentage
, sensory adaptation - CORRECT ANSWERS ✔✔diminished
|\ |\ |\ |\ |\ |\
sensitivity as a consequence of constant stimulation |\ |\ |\ |\ |\ |\
perceptual set - CORRECT ANSWERS ✔✔a mental predisposition |\ |\ |\ |\ |\ |\ |\ |\
to perceive one thing and not the other
|\ |\ |\ |\ |\ |\ |\
wavelength - CORRECT ANSWERS ✔✔the distance from the peak |\ |\ |\ |\ |\ |\ |\ |\ |\
of one light or sound wave to the peak of the next.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
electromagnetic wavelengths vary from the short blips of cosmic |\ |\ |\ |\ |\ |\ |\ |\ |\
rays to the long pulses of radio transmission
|\ |\ |\ |\ |\ |\ |\
hue - CORRECT ANSWERS ✔✔the dimension of color that is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
determined by the wavelength of light; when we know as the |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
color names |\
intensity - CORRECT ANSWERS ✔✔the amount of energy in a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
light or sound wave, which we perceive as brightness or
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
loudness, as determined by the wave's amplitude |\ |\ |\ |\ |\ |\
pupil - CORRECT ANSWERS ✔✔the adjustable opening in the
|\ |\ |\ |\ |\ |\ |\ |\ |\
center of the eye which light enters
|\ |\ |\ |\ |\ |\
iris - CORRECT ANSWERS ✔✔a ring of muscle tissue that forms
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the colored portion of the eye around the pupil and controls the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
size of the pupil opening
|\ |\ |\ |\
