Sensation and Perception Chapter 4
Exam Q&A 100% Guaranteed Pass
Define sensation. - ✔✔The elementary units of an experience.
Define perception. - ✔✔Organizing the sensations to make a meaningful
interpretation.
What is a subliminal perception? - ✔✔The processing of sensory information
that occurs below the limen (that is) the level of conscious awareness.
-When researchers subliminally trigger emotions by exposing participants to
words related to anger, these participants are more likely to rate other people
as hostile.
Explain the roles of rod vision. - ✔✔-Long and narrow; enable us to see basic
shapes and forms.
-Rely on them to see in low levels of light.
-More plentiful, not in the fovea
Explain the roles of cone vision. - ✔✔-Perceive color (found in the fovea)
-receptor cells in the retina allowing us to see in color

, Compare the trichromatic and opponent-process theory of color vision. - ✔✔-
Trichromatic theory: We base our color vision on 3 primary colors (Blue, green,
and red).
-Opponent process theory: Furthers the trichromatic theory to explain
afterimages. We perceive colors in terms of three pairs of opponent cells (red or
green, blue or yellow, or black or white). Our nervous system uses both
principles during color vision, but different neurons rely on one principle more
than the other.
Describe the properties of sound that are responsible for translating the
auditory message (including frequency, pitch, and amplitude). - ✔✔-Frequency:
the tighter the waves are packed, the higher the frequency
-Pitch: how high or how low a sound is
-Amplitude: height of the wave = how loud it is
-Timbre: the quality or complexity of the sound
Are there any links between our different senses? - ✔✔Yes, what we can hear
can be influence by what we see. Ex: The McGurk Effect (We hear "ba ba ba"
but the person is actually saying "ga ga ga").
What is the structure of the ear? - ✔✔-Outer ear
-Middle ear
