1. Starter What your exam will look like

2. Learning Objectives Lesson 1 & 2 To identify examples of Gestalt laws. To understand and evaluate the Gestalt theory of illusions. To recognise the differences between the Gestalt theory and Gregory’s theory, and their relative strengths and weaknesses.

3. Gestalt Theory of Illusions To understand Gestalt’s theory, first you need to understand the Gestalt Laws. –The whole is worth more than the sum of the parts –Figure and Ground –Similarity –Proximity –Continuity –Closure Use the worksheet, to draw illustrations for each Gestalt law in your books and write a sentence beside explaining them.

4. Gestalt Theory What are illusions? –Fictions –After effects –Ambiguous Figures –Distortions For each illusion read the information and write a simple definition in your book.

5. Gestalt Theory The Gestalt Laws suggest that our perception organises the parts of a stimulus into a ‘whole’ For example, we saw how we perceive groups and continuous lines using the laws of proximity, continuity and similarity. Because of figure-ground we separate ‘objects’ from ‘backgrounds’ Select two examples of illusions we have studied in the last few weeks, and explain them using Gestalt theory, use the worksheet to help you.

Compare responses for and against the 2 theories about Illusions: Gestalt forGestalt Against Gregory ForGregory Against Perspective law explains distortion illusions Cannot explain any distortions other than Muller-lyer Linear Depth cues enable illusions Curved lines don’t work like linear depth cues Uses different explanations at different times Size constancy enables illusions Can help to explain ambiguous figures
