Visual Perception

Question 1

Biological factors that influence visual perception

Answer 1

Are grounded in physiology (functions of the body) are also similar for most people. Except where some difference functionality is experienced by an individual due to genetics, injury, age or some other biological reason

Question 2

Biological depth dues

Answer 2

Is the ability to judge distance and see the world in three main dimensions, helps it to determine how near or far an object is from another object or ourselves.

Monocular depth cues: replies on visual information perceived by one eye
Binocular depth cues: from two eyes

Question 3

Binoculars depth cues

Answer 3

Requires both eyes to send information to the brain to perceive depth.

Question 4

Convergence

Answer 4

Involves the inward turning of the eyes, Whitch is detected by the brain as tension changes in the muscles surrounding the eye

Close objects- eyes converge inward = stronger more muscle tension =visual cortex is activated and brain interprets the objects as being close in proximity

Question 5

Retinal disparity

Answer 5

Refutes to the brain detecting similarities and differences between the information being sent from each eye.

Greater disparity = object is close
Less disparity = object is far

Question 6

Monocular depth cues

Answer 6

Require only one eye to send information to the brain to perceived death.

Question 7

How Monocular depth cues work
- accomodation

Answer 7

Accommodation involves the automatic focusing mechanism of the lens in the eye

The ciliary muscles control the lens making it bulge to focus on nearby objects and in Longgate to focus on far away objects .

The brain monitors the movement of the ciliary muscles and uses this information to determine the death and distance of an object in focus

Question 8

Perceptual set (phycological factor)

Answer 8

With regard to top-down processing each persons perception set is different and shapes. How we perceive stimuli. It is informed by past experiences and memory, your motivations and the context in which you are experiencing the stimuli.

Past experiences
Memory
Motivation
Context

Question 9

Perceptual set
Past experiences

Answer 9

Our expectations are influenced by our life experiences. Factors including culture and social backgrounds, family friendships and education.

Question 10

Perceptual set
Memory

Answer 10

The system that actively receives organises stores and recalls information. Our memory is shaped by Alex experiences and helps us understand how the world works playing an important role in our expectations.

Question 11

Perception set
Motivation

Answer 11

Influenced by our individuals desires depending on our motivation we will perceive certain stimuli that align with our goals as more salient than others.

Question 12

Perception set
Motivation

Answer 12

Influenced by our individuals desires depending on our motivation we will perceive certain stimuli that align with our goals as more salient than others.

Question 13

Perception set context

Answer 13

Context is the situation or condition in which something occurs for our purpose. It is the location and the circumstances in which the visual stimulates are being produced

Question 14

Perceptual constancy

Answer 14

The ability to proceed shifting information sent to the brain about an object and know that the object hasn’t actually changed in size, shape or orientation.

Perceptual constancy is used to perceive a visual stimulate as remaining constant . Size constancy, shape constancy and orientation constancy

Question 15

Size constancy

Answer 15

Recognises that a visual stimulator actual size remains the same despite change in the information sent to the brain about the size of stimulus

Question 16

Shape constancy

Answer 16

Recognises that a stimulus actual shape remains the same despite change in the shape of the retinal images sent to the brain

Question 17

Orientation constancy

Answer 17

Recognises that a stimulus actual orientation remains the same despite change in the orientation of the retinal images sent to the brain

Question 18

Gestalt principles

Answer 18

Figure- ground
Closure
Proximity
Similarity

Question 19

The gestalt
Figure ground

Answer 19

The tendency to perceive part of a visual stimuli as more relevant (the figure) and standing out against its less relevant surround (the ground) the line of separation between the figure and the ground is termed the contour and it helps to differentiate the figure from the ground

Question 20

The gestalt principle of closure

Answer 20

Refers to our ability to close up, fill in or ignore gaps in visual stimuli and perceive objects as a meaningful hole

Question 21

Similarity gestalt principal

Answer 21

tend to group together a whole any stimulate that are like in size shape or colour 

Question 22

Proximity gestalt principle

Answer 22

Proximity is the tendency to perceive the parts of a visual stimulus that are close together rather than spaced far apart as belonging to a group

Question 23

Social factors that influence visual perception

Answer 23

Culture
The community in which we live including the people we are surrounded by and associate with helps to shape how we see the world this influence can take the form of traditions value systems attitudes, and beliefs pass down through generations
