Does perceptual set involve bottom up or top down processing? Why?

• Top-down processing because it involves using expectations and prior experience to make sense of/process information

• Random processing because it involves using expectations and prior experience to make sense of/process information

• Bottom-up processing because it involves using expectations and prior experience to make sense of/process information

What is perceptual set?

• Perceptual set is a type of sensory memory.
• Perceptual set refers to the physical characteristics of stimuli.
