The filled interval effect in time perception depends on attentional focus. Listeners' estimations of melody duration changed based on whether they focused on detailed contour or overall phrase structure.

Area of Science:

  • Auditory perception
  • Cognitive psychology
  • Music cognition

Background:

  • The filled interval effect describes how the perceived duration of an interval changes based on its contents.
  • Attentional focus is known to modulate various perceptual and cognitive processes.
  • Understanding how attention influences time perception is crucial for explaining subjective experience.

Purpose of the Study:

  • To investigate if different attentional perspectives influence the filled interval effect.
  • To determine how focusing on lower-order vs. higher-order musical structures affects duration judgments.
  • To explore the relationship between event coherence, dynamic attending, and time estimation.

Main Methods:

  • Experimentally comparing the perceived duration of paired melodies with varying structural features.

  • Utilizing musically sophisticated listeners to ensure accurate perception of musical structure.
  • Manipulating attentional focus by instructing participants to track either melodic contour or phrase periodicity.
  • Main Results:

    • Duration estimations were significantly influenced by the hierarchical level of musical structure attended to.
    • The same pair of melodies could lead to overestimations or underestimations of duration.
    • Selective attention to lower-order contour changes or higher-order phrase timing altered time perception.

    Conclusions:

    • Attentional perspective is a key factor modulating the filled interval effect in auditory perception.
    • The dynamic attending theory provides a framework for understanding how attention to different structural levels impacts time estimation.
    • Event coherence and attentional modes are linked to the subjective experience of time during auditory event processing.
