Transduction correct answers process of converting sensory information into neural activity that
the brain can interpret
What is Doctrine of specific nerve energies? correct answers idea that separate brain areas are
specialized for different sensory inputs
Orienting responses correct answers occur when surprising and new events capture our attention
sensory adaption correct answers devoting less attention to very familiar stimuli (boredom)
Absolutely threshold correct answers minimum amount of energy or stimulus we can detect 50%
of the time
difference threshold correct answers smallest difference between stimuli we can detect 50% of
the time
Weber's/ Fechner's law correct answers differences in intensity are harder to detect at higher
intensities
Signal detection theory correct answers people's personal threshold for reporting stimulus
presence or change in stimulus intensity differ between people
Figure ground principle correct answers use of visual features to separate objects from
background
law of similarity correct answers grouping objects by common features
law of proximity correct answers grouping objects together according to closeness in space
law of continuity correct answers grouping features together when separated by another object
law of closure correct answers features with missing pieces of the are of the same object
Difference between bottom up processing and top down processing correct answers Bottom-up:
perception derived from sensory inputs
top down: perception derived from prior experiences/ expectations (causes misunderstandings)
Divided attenion correct answers when one multi-tasks and are not focussed on one thing
Intentional Blindness correct answers failure to perceive because you are busy focussing on
something else
What determines high saturation and low saturation? correct answers High: light consisting of
mostly one wavelength
, Low: light consisting of a mixture of different wavelengths
Order of eye structure at which light hit it correct answers Sclera > Cornea > Pupil > iris > lens >
retina
Sclera correct answers white outer shell
cornea correct answers clear part in front
pupil correct answers dark opening
iris correct answers part of pupil that has color
Where are the lens and what function do they carry? correct answers -clear part behind iris
-Accommodation: changes shape to bend light and direct it to the right spot
where and what is the retina and what is its function? correct answers -layer if light receptors
called photoreceptors at the back of the eye
-carries out transduction: receptors convert light into message that the brain can interpret
What do ganglion cells do? correct answers take signals from photoreceptors and send them to
the brain
Optic Nerve correct answers where axons of ganglion cells are bundled togehter
Optic disc correct answers area on retina without photoreceptors (blind spot)
Fovea correct answers central region of retina
What are the two types of photoreceptors and give points about them correct answers 1) Rods -
very sensitive to light and dominates outside of fovea, representing periphery of visual field
2) Cones - less sensitive to light and dominates centre of fovea, representing centre of visual
field
What is dark adaption? correct answers cones and rods adjust their sensitivity for darker lighting
conditions
Trichromatic theory correct answers color vision is determined by 3 cone types the record red,
blue, and green wavelengths
Opponent process theory correct answers patterns of neutral signals that pit pairs of color in
opposition: red vs green, blue vs yellow
Negative after image effect correct answers staring at one color too long and then looking
elsewhere, the opposite color appears
