PERCEPTION AND SENSATION

Question 1

SENSATION

Answer 1

• A psychological process involving sensory reception detecting and responding to stimuli

Question 2

PERCEPTION

Answer 2

• A mental process of organising and interpreting sensory stimuli sent from the sensory organs

Question 3

STAGES OF PERCEPTION

PERCEPTION - TAKING IN THE LIGHT

Answer 3

• Perception begins with the reception when a stimulus is detected at a sensory receptor site (eye, ear)

Question 4

TRANSDUCTION - TURNING THE LIGHT INTO SIGHT

Answer 4

• If the light stimulus is intense enough to activate the photoreceptors they will convert the light energy into electrochemical energy required for neural implies

Question 5

TRANSMISSION - FROM EYE TO BRAIN

Answer 5

• Electrochemical charged neural impulses leave their receptors sight and travel along specific neural pathways to particular locations in the brain for processing

Question 6

GESTALT PRINCIPLES

Answer 6

• A group of principles that organise visual perceptual features and then integrate them into connected patterns or whole forms

Question 7

FIGURE GROUND

Answer 7

• The view perceptually groups and separates some features of the stimulus so that part of a stimulus appears to stand out as an object against the background

Question 8

CLOSURE

Answer 8

• Refers to the view perceptual tendency to perceptually complete an incomplete figure by filling in an imaginary contour line

Question 9

SIMILARITY

Answer 9

• Tendency to perceive stimulus that have visual features (size, shape, colour and form) as belonging together forming a meaningful single unit or group

Question 10

PROXIMITY

Answer 10

• Stimuli close together in a space are perceived as belonging together
