 How do we perceive depth? | through binocular (two eyes) or monocular (one eye) cues. |
| Retinal disparity (binocular) | 2 eyes receive slightly different images. Closer the image - greater the disparity. |
| Convergence (binocular) | Eyes move inwards to focus on close objects, the amount the eye moves indicates how far it is away. |
| Superimposition (monocular) | Object overlaps or obscures another object behind |
| Texture gradient (monocular) | Closer objects can be seen in more detail than distant objects. |
| Relative height + size (monocular) | smaller or higher up in the visual field. |
| Convergence (monocular) | parallel lines converge as they do into the distance |
| Shading (monocular) | Objects in the foreground are darker and clearer than those in the distance. |
| Size constancy | A man in a picture is smaller than one closer - perceive they are the same height when placed next to each other. |
| Shape constancy | Objects seen from different angles are perceived as the same object. |
| Colour constancy | Depends on the illumination = still see it as the same |
| Location constancy | We perceive the world as stationary. |
| IDA | Nature/Nurture Psychology as a science = (Gibson +Walk) |
| Gibson + Walk | 36 babies aged 6-14 months - put on a glass top table with a checker board design. Other half was in clear glass with the design 4ft under. Found that babies refused to crawl over it which shows they understand depth perception |
