perceptual development (cognitive)

Question 1

what are visual cues?

Answer 1

things in visual line that are used to determine distance

Question 2

what is depth perception?

Answer 2

ability to see objects in 3D rather than the 2D that hits the retina

Question 3

what is perception built on?

Answer 3

experiences and cultural norms

Question 4

what are examples of depth cues?

Answer 4

• relative size = judge how far away something is based on size of other objects
• texture gradient = how detailed something is determines how close it is

Question 5

How old are infants when depth cues develop?

Answer 5

around 5 months

Question 6

what is pattern perception and when does it develop?

Answer 6

process of identifying complex forms and shapes = 3-4 months

Question 7

what is face perception and when does it develop?

Answer 7

ability to recognise a face in a visual scene = around 7 months

Question 8

what are constancies and when do they develop?

Answer 8

tendency to percieve familiar items as standard shapes and sizes no matter stimuli changes = 6 months

Question 9

What are ways of investigating perceptual development?

Answer 9

1- habituation / gazing task = how bored babies get when seeing new stimuli
2- preferential looking = drawn to shapes that resemble contrasts of a face
3- pyshiocogical measures e.g., heart rate and brain scans
4- deprivation tasks = free kitten vs yoked kitten = yoked kitten had poorer perceptual skills

Question 10

How does going from crawling to walking impact the depth perception of infants?

Answer 10

have to re-learn depth perception when start walking
