THE EFFECT OF VIEWING CONDITIONS AND INSTRUCTIONS ON SHAPE JUDGEMENTS (pages 49-57)

A study using different groups of naïve subjects in forty‐eight experimental conditions showed that instructions and viewing conditions significantly affected shape judgements. Apparent and ‘non‐directing’ instructions resulted in similar judgements which were as stable as judgements made by subjects who received objective (real shape) or projective (visual angle) instructions. Judgements given under apparent and non‐directing instructions tended to follow the visual angle expectation under reduced viewing conditions and under conditions of extreme slants. Under improved viewing conditions and with moderate slants they followed the real shape expectation.
