Ch 4-6 Flashcards
(34 cards)
How does light stimuli reach us?
Light will reflect light waves in a particular environment.
Inversion of light
Cornea–>pupil–>translens–>retina
Rods
Working in dim light, brightness, darkness.
Cones
Color, key features, most involved.
Mammalian visual system
From retina to the brain.
The auditory cortex
The cortex responds to specific frequencies.
Ex)
Sound,location via loudness, arrival time, and phase.
Vestibular system
Direction, tilt, and acceleration of the head. Also sensation of the body and movement.
Hair cells are stimulated by
Otoliths in semicircular canal fluids.
Phantom limb syndrome
Reorganized sensory representation neurons reorganize and inner ate other parts of the body after loss of a limb.
Taste buds are in the
Papillae
There are five taste receptors
Adaptation, temporal coding, lonotropic& meabortropic effects, and taste sensitivity.
Taste sensitivity
Depends on the number of fungiform papillae.
Olfaction used for
Detecting, flavor, and social messaging.
Research designs for development
Longitudinal and cross sectional studies
Cohort effects
Active in one group and non active in another.
The fetus&newborn
Zygote–>embryo–>fetus
Trichromatic theory
Wavelength specific cones
Opponent process theory
After images and exciationy inhibition patterns.
Retinex theory
Retinal stimulation aggreated.
Classical (Pavlovian) conditioning
Language unconditioned stimulus and response conditioned stimulus and response.
Operant Conditioning
Thorndikes puzzle box
Positive
Adding something to the environment.
Negative
Something you take from the environment to make them do it again.
Primary
Things that don’t require second to nature (survival)
