1

The set of processes by which we recognise, organise, and make sense of the sensations we receive from environmental stimuli

perception

2

In regards to the perceptual continuum of vision, what is an example of a distal object?

grandmas face

3

What happens in the informational medium?

light is being reflected of grandmas face (visible electromagnetic waves)

4

What is the proximal stimulation?

photon absorption in the rod and cone cells of the retina., the receptor surface in the back of the eye.

5

What is an example of a perceptual object?

grandmas face

6

______ occurs when sensory receptors change their sensitivity to the stimulus. Constant stimulus leads to lower sensitivity.

Sensory adaptation

7

When parts are identified, put together, and then recognition occurs is knows as what theory of perception?

bottom-up theory

8

People actively construct perceptions using information based on expectations, this is known as what theory of perception?

top-down theories

9

What are four types of bottom-up processing theories?

direct perception, template theories, feature-matching theories and recognition-by-components theory

10

The information in our sensory receptors is all we need to perceive anything. We do not need the aid of complex thought processes to explain perception. What theory is this?

Gibon's theory of direct perception

11

Multiple templates are held in memory. To recognise the incoming stimuli, you compare to templates in memory until a math is found. What theory is this?

Template theory

12

Recognise objects on the basis of a small number of characteristics (features). What theory is this?

Feature-matching theory

13

What are the four kinds of demons in the pandemonium model?

Image demons, feature demons, cognitive demons and decisions demons

14

What theory breaks objects down into geons?

Recognition-by-components theory

15

______ processing occurs quickly and involves making inferences, guessing from experience, and basing one perception on another.

Top-down

16

What are the 5 gestalt principles?

proximity, similarity, continuity, closure and symnetry

17

Individuals organise their experience in as simple, concise, symmetrical, and complete manner as possible is known as

Law of Pragnanz

18

The ability to see the world in 3 dimensions and detect distance:

Depth perception

19

Three examples of monocular depth cues:

texture gradients (grain of item), relative size (bigger is closer), interposition (closer are in front of other objects)

20

Three more examples of monocular depth cues?

linear perspective, Aerial perspective and motion parallax

21

Parallel lines converging in the distance is known as?

linear perspective

22

Images seem blurry the farther away they are is known as?

aerial perspective

23

Objects get smaller at decreasing speed in decreasing speed in distance is known as?

motion parallax

24

What are two binocular depth cues?

binocular convergence and binocular disparity

25

eyes turn inward as objects moves towards you, brain uses this information to judge distance:

binocular convergence

26

Each eye views a slightly different angle of an object; brain uses this to create a 3D image:

binocular disparity

27

Inability to recognise and identify objects or people, despite having knowledge of the characteristics of the object or people:

agnosia

28

Normal visual field, yet act blind. Perceives only one stimulus a time - single word or object:

simultagnostic

29

Inability to recognise faces, including own face:

prosopagnosia

30

Cannot use vision to guide movement. Unable to reach for items:

Optic ataxia
