Explain terminology to describe figure. Psychology 0044 Sample Lab Report Page 1 Introduction An optical illusion occurs when our perception of an object differs from physical reality. Perceptual compromise was investigated, by measuring the impact of global and local processing on perceptions of size, as modulated by Navon stimuli. The Müller-Lyer effect, the apparent difference in the length of a line as the result of its adornment with arrowheads or arrow tails, is the best known and most controversial of the classical geometrical illusions. When viewers are asked to place a mark on the figure at the midpoint, they invariably place it more towards the "tail" end. Muller-Lyer Lab Report Contents .

Lines with arrows pointing outwards are usually considered shorter than those with arrows pointing inwards. Another example of an optical illusion is the Horizontal-Vertical illusion. Visual illusion classification Illusions of length: Horizontal-Vertical, Muller-Lyer Psychological Mechanism(s) Empirical investigation Measuring size of an effect Method of adjustment, method of limits Reporting Psychological Investigations Structure of Report Content of Report The Müller-Lyer illusion is an optical illusion consisting of three stylized arrows.
