Topic: Visual Perception

Question 1

Perception

Answer 1

The way we interpret sensation and therefore make sense of everything around us

Question 2

Reception

Answer 2

When light energy enters the eye and focuses on the retina

Question 3

Transduction

Answer 3

When light energy is converted into nerve impulses

Question 4

Transmission

Answer 4

When the nerve impulses travel via the optic nerve to the optical lobe

Question 5

Selection

Answer 5

When the image is pulled apart by cells called feature detectors

Question 6

Organisation

Answer 6

When the visual information reaching the brains visual cortex is recognised using three groups of visual perceptual principles

Question 7

Interpretation

Answer 7

The temporal lobes give the object meaning

Question 8

Electromagnetic spectrum

Answer 8

Describes the various types of electromagnetic radiation based on their wave length. We can see light between 360 and 760 nanometers

Question 9

Rods

Answer 9

125 million in each eye. Responsible for vision in low light and for peripheral vision. Only register in black and white.

Question 10

Cones

Answer 10

6 million 500 thousand in each eye. Responsible for detail, colour and black and white vision in daylight

Question 11

Size constancy

Answer 11

We maintain a constant perception of an objects size, even though it may be getting closer or moving further away.

Question 12

Shape constancy

Answer 12

We maintain a constant perception of an objects shape even though it may rotate

Question 13

Gestalt

Phi Phenomenon

Answer 13

The perception of movement created by rapid presentation of a series of stationary stimuli

Question 14

Gestalt

Figure ground

Answer 14

Images are organised into the central object of attention and background

Question 15

Gestalt

Closure

Answer 15

We may perceive an object of being whole when it is actually incomplete

Question 16

Similarity

Answer 16

Elements which are similar in appearance may be seen as a whole

Question 17

Proximity

Answer 17

Elements which are in a close proximity of one another may be seen as one unity

Question 18

Binocular depth cue

Retinal disparity

Answer 18

The retina of each eye receives slightly different images snd fuses them together

Question 19

Convergence

Answer 19

The automatic turning of the eyes inwards as we watch an object approaching

Question 20

Monocular depth cur

Accommodation

Answer 20

The ciliary muscles of the eye change the curvature of the lens to focus on the image on the retina

Question 21

Monocular depth cue

Linear perspective

Answer 21

Parallel lines appear to converge as they retreat into the distance

Question 22

Monocular depth cue

Interposition

Answer 22

Objects being overlapped are perceived as being further away

Question 23

Monocular depth cue

Texture gradient

Answer 23

Texture in the foreground is more detailed than in the background

Question 24

Monocular depth cue

Relative size

Answer 24

We perceive the object producing the largest retinal image as the nearest

Question 25

Monocular depth cue

Height in the visual field

Answer 25

Portrays the objects further away as being closer to the horizon

Question 26

Perceptual set

Answer 26

A predisposition to attend to certain aspects of a stimulus. Can be influenced by context, motivation, emotion and precious experience

Question 27

Ponzo illusion

Answer 27

Horizontal line in each diagram appears to be bigger due to hight in the visual field and linear perspectice

Question 28

Muller Lyer illusion

Answer 28

Feather tails is perceived as being longer due to the gestalt principle of closure

Question 29

Sensation

Answer 29

The process of sensing our environment through the five senses.
