Question 1

What are the 4 gestalt principles?

Answer 1

Figure-ground
Similarity
Proximity
Closure

Question 2

What is accommodation

Answer 2

Lens bulges to focus on close objects, lens flattens to focus on far objects

Question 3

What is motion parallax

Answer 3

Uses movement to gauge how far something is

Question 4

What is linear perspective

Answer 4

The apparent convergence of parallel lines as they go into the distance

Question 5

What is interposition

Answer 5

When one object overlaps another, the covered object is perceived as further away

Question 6

What is texture gradient

Answer 6

The more detail, the closer something is

Question 7

What is relative size

Answer 7

If something creates a smaller retinal image, it is perceived as further away

Question 8

What is height in visual field

Answer 8

The closer something is to the horizon, the further away we perceive it as

Question 9

What are photoreceptors

Answer 9

Sensory receptors of the eyes which receive light and convert this sensory information into a form that can be sent to the brain.
Changes electromagnetic energy into electrochemical energy.

Question 10

Retinal disparity

Answer 10

A binocular depth cue
Our eyes are about 6-7cm apart, this means that each retina receives a slightly different image

Question 11

Bottom-up processing

Answer 11

Info processing where perceptual experiences are created by building larger wholes from minute aspects of sensory data (slower)

Question 12

Top-down processing

Answer 12

Info processing where psychological, social, and contextual info is applied and influences the perception of stimuli

Question 13

RTTSOI?

Answer 13

Reception
Transduction
Transmission
Selection
Organisation
Interpretation

Question 14

What are rods and cones?

Answer 14

Photoreceptors in retina
Rods: Low light
Cones: colour

Question 15

What is convergence?

Answer 15

Eyes turn inward for close objects

Question 16

What is Counterbalancing?

Answer 16

All participants complete each condition, but half of the participants experience the conditions in the reverse order

Question 17

Divided attention

Answer 17

Allows us to process multiple sources of information or stimuli more effectively.

Question 18

What is Selective Attention

Answer 18

Allows us to focus on one task

Question 19

Perception set: (related to skittles experiment

Answer 19

Certain colors of skittles to have specific flavours.

Question 20

Synesthesia

Answer 20

Experience the perception of flavor differently from other participants as one stimulus could activate sensory systems. This could act as an extraneous variable.

Question 21

What is Relative size?

Answer 21

If two objects are the same size, then the object that produces the larger image on the retina will be perceived as closet.

Question 22

What is Spacial Neglect?

Answer 22

Refers to an inability to perceive or orient sensory information located within on side of the space. Individuals with Spatial neglect do not have malfunction senses.

Question 23

Dot to dot experiment:
Selective and divided attention

Answer 23

Selective = Dot to Dot
Divided = Dot to Dot + Singing.

Question 24

IV and DV

Answer 24

IV= Singing
DV= How many answers you got right

Question 25

Conclusion of Dot to Dot

Answer 25

It can be concluded that using divided attention had a negative impact on task completion compared to when participants did not need to divide their attention.

Question 26

Primary and Secondary Data: (Dot to Dot)

Answer 26

Primary = Data collection
Secondary = Didn’t collect any
