Visual perception images (organisation & interpretation)

The document discusses Gestalt principles, which are theories about how humans organize visual elements into groups and perceive relationships among them. Specifically, it describes principles of depth perception, in which monocular and binocular cues allow us to see in three dimensions. It also examines visual illusions that demonstrate how Gestalt principles can cause us to perceive images differently than their actual properties.

Editor's Notes

#3 Figure-groundWe see these objects as figures against the background.
#4 ClosureHere, gaps are closed to make a complete figure.
#5 SimilarityIn these examples, organisation depends on similarity of colour and/or shape.
#6 ProximityNotice how differently a group of six or nine objects can be perceptually organised, depending on their spacing.
#21 Figure 3.24 a Are the centre dots in both figures the same size? b Context alters the meaning of the middle. (Adapted from Bruner & Minturn, 1955)

#24 Figure 3.16 Pictorial cue:Linear perspective
#25 Figure 3.16 Pictorial cue: Relative size
#26 Figure 3.16 Pictorial cue: Interposition
#27 Figure 3.16 Pictorial cue: Texture gradient
#28 Figure 3.16 Pictorial cue: Height in visual field
#37 Figure 3.21 Necker’s cube.
#38 Visual illusion 1: Is the diagonal a straight line? Check it with a ruler.
#39 Visual illusion 2:Is this a drawing of a staircase descending from upper left to lower right, or is it a view from under a staircase from lower right to upper left?
#40 Visual illusion 3:Are these lines parallel? Cover some of the slash marks to see.
#41 Visual illusion 4:Which line is larger: the horizontal or the vertical line?
#42 Visual illusion 5:Notice how the background distorts the square.
#43 Visual illusion 6:Which shape is larger?
#44 Visual illusion 7:Which column is shortest? Which is longest?
#45 Figure 3.29 The Müller-Lyer illusion. Which of the horizontal lines is the longer?
#46 Figure 3.31 The Ames room. From the front, as shown in a and b, the room looks normal; the actual right-hand corner is very short and the left-hand corner is very tall. The diagram in c shows the shape of the room and reveals why people appear to ‘grow’ as they cross towards the nearer, shorter right-hand corner. The floor plan in d shows people’s actual positions in the Ames room in relation to the viewer.
