Q

made up of three components: hues, intensity, and saturation.

20
Q

3 COMPONENTS OF COLOUR

A
  1. Hue
  2. Intensity
  3. Saturation
21
Q

is determined by the spectral wavelength of light.

22
Q

is the brightness of the color. The brightness or dullness of a color.

23
Q

is the amount of whiteness in the color.

24
Q

compensates for the movement of the image on the retina.

A

Visual Processing

4 ACTIVITIES FOR THE SENSES
1. Reading 2. Hearing 3. Touch 4. Movement
26
in reading, this is a type of eye movement used to move the fovea rapidly from one point of interest to another.
Saccade
27
in reading, pertains to the maintaining of focus on just one location, perception occurs during here.
Fixation
28
3 PHYSICAL APPARATUS OF THE EAR
1. Outer Ear 2. Middle Ear 3. Inner Ear
29
the visible part of the ear and protect the sensitive middle ear from damage.
Outer Ear
30
transmits sound waves as vibration to inner ear.
Middle Ear
31
where chemical transmitters are released and cause impulses in auditory nerve.
Inner Ear
32
in sound, this pertains to the sound frequency.
Pitch
33
in sound, this pertains to the amplitude
Loudness
34
in sound, this pertains to the type of quality
Timbre
35
3 PROCESSES OF THE MEMORY
1. Sensory -> attention -> 2. Short-term memory -> rehearsal -> 3. Long-term memory
36
this exists for each sensory channel.
Sensory Memory
37
is the concentration of the mind on one out of a number of competing stimuli or thoughts.
Attention
38
3 TYPES OF SENSORY MEMORY
1. Iconic Memory 2. Echoic Memory 3. Haptic Memory
39
this type of sensory memory is for visual stimuli.
Iconic Memory
40
this type of sensory memory is for aural stimuli.
Echoic Memory
41
this type of sensory memory is for touch.
Haptic Memory
42
acts as a “scratch pad” for temporary recalls of information.
Short-Term Memory
43
is the main resource. Is intended for long-term storage of information.
Long-Term Memory
44
Information is processed and applied to (4)
- reasoning - problem solving - skill acquisition - error

5 Effectors
- Limbs - Fingers - Eyes - Head - Vocal System
