Question 1 Report
Which of the following interpretations is most likely to show perceptual set? During a mathematics lesson, pupils briefly see an ambiguous symbol between the sequence 12 and 14. Most pupils report seeing 13, while pupils in an art club later describe the same symbol as the letter B.
(a) Name the factor that has influenced the pupils' perception. [1]
(b) Explain why the two groups give different reports of the same visual information. [3]
Answer Details
(a) Perceptual set / expectation [1] (b) The mathematics pupils expect a number because of the surrounding number sequence [1]; the art pupils are primed to expect letters / symbols [1]; prior knowledge or context leads the brain to interpret the ambiguous stimulus differently [1].
