Perception Flashcards
Monocular depth cues
Cues that allow a person to judge depth and distance using one eye
Types of monocular depth cues
– height in plane
– relative size
– occlusion
– linear perspective
Height in plane
Objects that are higher individual plane appear further away
Relative size
When objects appear smaller than the known size, they are perceived as being further away
Occlusion
Objects that are behind or obscured by another object of perceived as further away
Linear perspective
Lines at our parallel to get closer and meet
Binocular depth cues
– Retinal disparity
– Convergence
Factors affecting perception
– culture
– emotion
– motivation
- expectation
Perception set
The tendency for our brain to notice certain aspects of the environment more than others
Culture
The social world that surrounds you. Culture influences us through beliefs and expectations.
William Hudson (1960)
People from different background/education use depth cues differently and have different perceptual sets
This supports Gregory’s constrictive theory as it shows death cues are learnt.
Perceptual set and emotion
The tendency for our brains you noticing that are exciting interesting or unusual but also block things that may go anxious or we find threatening
Perceptual set and motivation
The fault that drives your behaviour can affect how you receive things in the environment wanting something can increase it’s attractiveness
Gilhirst & Nesberg (1952) aim
To find out if food that probation affects the perception of pictures of food
Gilhirst & Nesberg (1952) method
Two groups of students one group deprived food for 20 hours in a control group (not hungry). Students were shown four sides each one showing a meal, the slides of display 15 seconds. The pictures were shown again, but dimmer and the participants had to adjust the lighting to make it the same as it did before.
