Q

Monocular Depth Cues

A

Accommodation, Pictorial Cues

17
Q

Accommodation

A

Automatic adjustments of our eye lens to focus on an object to change how far away the object is.

18
Q

Binocular Depth Cues

A

Convergence and retinal disparity

19
Q

Convergents

A

Detecting depth by changing tension in the eye muscles.

20
Q

The five Depth Perception

A

Linear Perspective, Interposition, Texture Gradient, Relative Size and height in the visual field.

21
Q

Liner perspective

A

The meeting of parallel lines as they go back into the distance to give depth

22
Q

Interposition

A

Overlap, When one abject slightly covers another and the object furthest is the one being covered.

23
Q

Texture Gradient

A

Reduced detail that occurs in a surface as it becomes further away

24
Q

Relative Size

A

To visually see that the object largest in view is closest and the object that is smallest is further away.

25
Influences of Visual Perception
Perceptual set, context, motivation, emotional state, culture.
26
Perceptual Set
To see something in what we expect to see.
27
Five Basic Taste
Sweet, Sour, Savoury, Salty and Bitter
28
Influences on Taste Perception
Age, Genetics, Perceptual set, Culture
29
Judgement of flavours
Perceptual set, Colour intensity and texture.
30
Stimulus - Taste
Chemical molecules combine with saliva on your tongue.
31
Reception - Taste
Taste receptors located in taste buds that are grouped within the papillae.
32
Transduction - Taste
Convert chemical molecules into signals transmitted to the brain by the facial nerve.
33
Perception - Taste
Facial nerve carriers send information to the thalamus then to the gustatory cortex.
34
Age and taste
The number of taste buds increase durning childhood and decrease with age.
35
Genetics and taste
Make us more or less sensitive to taste.
36
Synaesthesia
Stimulation of one sense stimulates another involuntary second sense. Unique to each person and is constant.
37
Retinal disparity
Difference between the way each eye sees an object when up close.
38
Height in the visual field
The closer an object is to the horizon the further away it is.
