1. Perception and memory 1- Perception 2- Memory

2. What is perception? A process by which the brain analyses and makes sense out of incoming sensory information. What are the three areas of perception? Segregation of objects (segregate objects from one another and their background) Perception of distance (Judge their distance from us) Recognition (Recognise what they are)

3. Segregation of objects – Perceptual organisation into figure and ground- when an object appears to stand out from the background in an obvious manner. – Figure is what you notice or focus on – Ground is less noticable and serves as the background for the figure

8. Segregation of objects Perceptual organisation of stimuli into coherent patterns (e.g. Grouping of stimuli by proximity) See book p226-227

9. Perception of distance https://www.youtube.com/watch?v=dS12p0Zqlt 0

10. Perception of distance is done using several visual cues such as Relative size The further away an object is situated from the eye, the smaller is it perceived to be.

12. Perceptual of distance is done using several visual cues such as relative size superimposition

13. When one object partially blocks the view of another, the blocked object is perceived to be further away. superimposition

14. Perceptual of distance is done using several visual cues such as relative size superimposition relative height in horizontal field.

16. relative height in horizontal field

17. Among a group of objects whose bases are below the horizon, those with their base in a relatively higher position appear to be further away, those with their bases in a lower position seem nearer

18. Perceptual of distance is done using several visual cues such as relative size superimposition relative height in horizontal field. linear perspective

19. Parallel lines converge in the distance linear perspective

20. Perceptual of distance is done using several visual cues such as relative size superimposition relative height in horizontal field. linear perspective Binocular disparity

23. The closer the object is to view the greater the disparity between the two images. The two images merge into one in the brain. This image indicates depth and distance of an image more effectively than either single eye. Perceptual constancy as objects become nearer and the viewing angle changes.

25. Perceptual constancy is the tendency to see familiar objects as having standard shape, size, color, or location, regardless of changes in the angle of perspective, distance, or lighting. http://www.dailymotion.com/video/xq1r fl_national-geographic-test-your-brain- episode-2-perception_shortfilms http://www.dailymotion.com/video/xq1r fl_national-geographic-test-your-brain- episode-2-perception_shortfilms
