PSYCH 230 UNIT 1 QUESTIONS AND ANSWERS
perception - Answers- the process of creating conscious perceptional experience from
sensory input
-changing sensory input into a meaningful conscious experience
sensation - Answers- registration of physical stimuli from the environment on sensory
receptors
-it changes physical stimuli into information in our nervous systems
basics of perception - Answers- stimulus --> sensation --> perception
receptors, transduction, neural response
neural transduction - Answers- receptors, transduction, and neural response
transduction process - Answers- the receptors take the physical stimulus in the
environment and they will transform it into an electrical, chemical signal that we call a
neural response
2 basics of perception - Answers- #1 it allows us to act on the environment
#2 phenomenology: an internal experience that we don't need to act on (ex: a sunset)
Hering - Answers- -colors are perceived through 2 pairs of opposing colors (4 primary
colors, not 3)
-against constructivism
-believed there was no need for unconscious inference
computational approach - Answers- -many things are done at the same time
-can do many computations at once
-flow of info does not always go in one direction
-more complex and biologically plausible approach to understanding perception
microelectrode - Answers- technique that involves taking an animal and taking out a
little part of their skull and using very little electrodes so we can implant them and study
the neurons that we are interested in studying.
visual agnosia - Answers- an inability to recognize objects
prosopagnosia - Answers- inability to recognize faces
-can only identify features, but not put faces together
electroencephalogram (EEG) - Answers- -put a cap on a participant's head with
electrodes and record activity
