Psychology

Learning objective To understand about stereopsis.

Read and discussion – what is stereopsis? Answer questions from textbook

TO UNDERSTAND ABOUT STEREOPSIS. What is stereopsis? What does the word make us think? Stereo Opsis Read Edexcel page 17 (A1b5)

TO UNDERSTAND ABOUT STEREOPSIS. http://www.youtube.com/watch?v=ghSR2bI5YSE http://www.youtube.com/watch?v=P9egHhipgng&list=PLSj5xHXOB7zg UZVTWIb8QpF8hwoTRSqch Edexcel page 17 (A1b5) – now answer the questions.

TO UNDERSTAND ABOUT STEREOPSIS. Can a person who is blind in one eye use stereopsis as a cue to depth? No. Stereo requires two fields of vision.

TO UNDERSTAND ABOUT STEREOPSIS. Sam looks out of his window with both eyes open and lines his finger up with a tree trunk. When he closes his left eye nothing happens, when he closes his rights eye his finger seems to jump away from the tree trunk. Is Sam left or right eye dominant? Right eye dominant.

TO UNDERSTAND ABOUT STEREOPSIS. Lucy is looking out of her window. First she looks at the cat just outside on the wall. Then she looks into the distance at a lorry. Will the difference between the left eye or right eye view be bigger when Lucy is looking at the cat or the lorry? The cat – because the cat is closest and the brain’s stereovision tells us that the lorry is smaller.
