Orienting Responce correct answers How quickly we change our attention to stimuli that signal

eg. watching tv, we don't pay attention to when the camera angle changes

William Gustav Fechner correct answers Psychophysics: field of study that explores how
physical energy and intensity relate to psychological experience

Absolute Threshold correct answers minimum amount of energy or quantity of a stimulus
required for it to be reliably detected at least 50% of the time it is present

Difference Threshold correct answers Smallest difference between stimuli that can be reliably
detected at lest 50% of the time
eg. salt on food

Signal detection theory correct answers a stimulus perceived depends on both sensory experience
and judgment made by the subject
1. sensory process
2. decision process

Sensory Process correct answers experimenter provides a fake stimulus or none at all

Decision Process correct answers subject asked to report whether or not a stimulus was actually

the objects in out environment and what parts are the background.

Proximity correct answers grouping based on closeness of space
eg. eggs 2 rows of 6 or 6 rows of 2

Similarity correct answers grouping objects together according to features
eg. people in uniform

Selective attention correct answers focusing on one particular event or task

inattentional blindness correct answers a failure to notice a clearly visible event or objects
because attention is directed elsewhere
eg. missing gorilla dance around
eg. refs in sports

Amplitude correct answers height of the wave

Saturation correct answers light that consists of a mixture of different wavelengths have low
saturation

, -light wavelengths that consist of mostly one wavelength have high saturation

Low amplitude correct answers used to see dim colours

High amplitude correct answers used to see bright colours

Sclera correct answers The white, outer surface of the eye

Cornea correct answers The colour layer that covers the front portion of the eye and contributes
to the ability to focus
-light enters the cornea and passes through the pupil

Pupil correct answers regulates amount of light that entries by changing its size, t dilates to allow
more light to genre and constrict to allow less light into the eye.

Iris correct answers the round muscle that adjust the size of the purple, gives eye colour.

Lens correct answers Clear structure focuses light onto the back of the eye

Retina correct answers lines the inner surface of they eye and consists of specialized receptors
that absorb light and send signals related to the properties of light to the brain

Ganglion cells correct answers gather information from photoreceptors
-respond to red

Optic nerve correct answers Dense bundle of fibres that connect to the brain

Blind spot correct answers a space that lacks photoreceptors

Does the brain fill in missing information? correct answers yes!

what are two types of photoreceptors correct answers Rods and cones

Rods correct answers photoreceptors that occupy peripheral regions of the retina; highly
sensitive under low light levels
- see black and grey

Cones correct answers photoreceptors that are sensitive to the different wavelengths of light that
we perceive as colour
- cluster around fovea

Fovea correct answers central region of retina

How many rods for every ganglion cell? correct answers 10
