Perceptual processes have inherent affect. When identical stimuli violate pleasant perceptual expectations, they are disliked, demonstrating perception

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Affective Science

Background:

  • Prior research indicates perceptual processes possess intrinsic affect.
  • Previous studies manipulated affect by varying stimulus categories.
  • This study advances understanding by manipulating expectations for identical stimuli.

Purpose of the Study:

  • To investigate how perceptual expectations influence affective responses to identical stimuli.
  • To determine if violating pleasant perceptual expectations leads to negative affect.
  • To provide stringent evidence for intrinsically pleasant or unpleasant perception.

Main Methods:

  • Conducted seven experiments using between-subjects designs.
  • Manipulated perceptual expectations for objectively identical visual stimuli.

  • Prevented participants' insight into the experimental manipulation to ensure validity.
  • Main Results:

    • Identical stimuli were visually disappointing and less liked when violating pleasant perceptual expectations.
    • These negative effects were specific to violations of perceptual expectations.
    • Results suggest perception is intrinsically pleasant or unpleasant, influenced by expectations.

    Conclusions:

    • Perceptual expectations significantly modulate affective responses to identical stimuli.
    • Violating pleasant perceptual expectations leads to decreased liking and disappointment.
    • Findings align with predictive coding frameworks and explain enjoyment of perceptual effort.
