Questions and Verified Answers |
Already Graded A+
are there really 5 senses? - 🧠 ANSWER ✔✔no; vision, hearing, smell,
taste, light touch, pressure, cold, heat, pain, itch, vestibular, proprioception
sensation - 🧠 ANSWER ✔✔registration of a physical stimulus on sensory
receptors; leads to perception
perception - 🧠 ANSWER ✔✔the process of creating conscious perceptual
experience from sensations
neural transduction - 🧠 ANSWER ✔✔receptors, transduction, neural
response
receptors - 🧠 ANSWER ✔✔specialized neural cells
transduction - 🧠 ANSWER ✔✔transforming into neural signal
,neural response - 🧠 ANSWER ✔✔
Aristotle and the 5 senses - 🧠 ANSWER ✔✔Aristotle illusion and motion
aftereffect
Aristotle illusion - 🧠 ANSWER ✔✔In the illustration, we see two crossed
fingers and a pencil touching in the middle. In this illusion, we feel as if we
have been touched by two pencils rather than one.
motion aftereffect - 🧠 ANSWER ✔✔a visual illusion experienced after
viewing a moving visual stimulus for a time with stationary eyes, and then
fixating on a stationary stimulus
Thomas Young - 🧠 ANSWER ✔✔colors are coded by three different kinds
of nerve fibers; light is a wave
Johannes Mueller - 🧠 ANSWER ✔✔doctrine of specific nerve energies
neural habituation - 🧠 ANSWER ✔✔neural responses to stimuli are
suppressed overtime
perceptual aftereffects - 🧠 ANSWER ✔✔dedicated neurons "represent"
particular stimulus; neurons get tired; without "full" contribution perception
is off
, Von Helmholtz - 🧠 ANSWER ✔✔perception is constructed from both
senses and cognitive processes; unconscious inference; three basic color
receptors
Hering - 🧠 ANSWER ✔✔colors are perceived through 2 pairs of opposing
colors (four primary colors, not three); measured speed of neural
transmission
Weber's Law - 🧠 ANSWER ✔✔the just-noticeable difference between two
stimuli is related to the magnitude or strength of the stimuli (ex. pencil on
paper vs. book)
JND - 🧠 ANSWER ✔✔larger stimulus = larger JND; smaller stimulus =
smaller JND
Fencher - 🧠 ANSWER ✔✔father of psychophysics, the study of relation
between physical stimuli and the perception they elicit
psychophysics - 🧠 ANSWER ✔✔the study of the relation between physical
stimuli and perception
Fencher's Law - 🧠 ANSWER ✔✔the relationship between physical stimuli
and perception is logarithmic - eventually, perception caps out
