Topic 3 perceptual development Flashcards
Gibson and walk
Aim to see if human children and young animals are able to perceive innately ?
Procedures
Children place on the glass
Shadowside, check-box and the glass
Deep and check-box on the floor
Mother stand at one and two encourage them to move closer
Sample: 36 children (6-14 month)
Result 100% shallow side, 11% deep end
Conclusion: children can perceived that by the time they can crawl
Animal study (highly controlled)
Chick, goat lamb (limp) , kitten (freeze) , dark rear rat - shallow end
Aquatic turtles , rats (whiskers)— deep end
Relative size : young and adult rats (learned)
Motion parallax : dark rare rats (innate)
Fantz- preference for complex pattern and faces
Children under age of five
More time looking at faces /pattern than plain colour
Innate perceptual ability to recognise face
Longer the gay the more he prefer stimuli
Operant conditioning : dummy/pacifier
If they see different with new stimulates, they would have faster sucking just like seeing the mother versus stranger
Hudson- cultural difference in perception
South African workers
A picture with Hunter Spear, the antelope and the antelope is near than the elephant
Two depth clues : overlapping objects/ known size
Questions
- What do you see?
- Which is nearer, antelope or the elephant
- What is the man doing?
Children and adult find it difficult
Cross-cultural study : history and culture effect perceptual set (nurture)
Blakemore and Cooper- kittens raised in different environment
Limit visual experience of kitten to compare behavioural and neurophysiological effect
two weeks old put in vertical or horizontal cylinder with glass platform and black collar and lid
Five hours per day up to 5 months
Being put in the lighted room at five months old
Pupillary Reflex normal , always clumsy
Initially navigate the room by touch , starter response and visual placing Lost
No neuron along to the opposite direction of the line in cylinder
Sensory integration therapy
Hyposensitive/ hypersensitive child
Assessed by occupation knows therapist and multidisciplinary team
Sensory diet Taylor to individuals including plan play activity
Activity: build on each other, match children highest skill, challenging overtime
Accommodation : adjustment to child environment for example classroom
Not training specific skills , the purpose is integrate all of the senses, activities will include other senses
Develop perceptual ability by exposed to sensory stimuli structured repetitive progressive way
However, only a few show positive results
