PRES: Pupil Responses to Pitch Deviants Reflect Predictability of Melodic Sequences Flashcards
What physiological measure is used to study predictability in melodic sequences?
Pupil response
What happens to pupil dilation when a pitch deviant occurs in a melodic sequence?
Pupil dilation increases.
What is a pitch deviant in the context of this study?
A deviation from the expected pitch in a melody.
How does the predictability of a melody affect listener response?
Predictable melodies result in smaller pupil responses, while unpredictable ones result in larger responses.
Which cognitive mechanism is reflected in physiological responses to pitch deviants?
Auditory prediction mechanisms.
What does increased pupil dilation signify in response to a pitch deviant?
Increased cognitive effort and attention.
Why is pupil dilation used as a measure in auditory studies?
It is a non-invasive indicator of cognitive and emotional processes.
What broader cognitive process does the study of pitch deviants contribute to understanding?
Prediction and adaptation mechanisms in auditory cognition.
How does the concept of auditory predictability relate to everyday listening experiences?
It helps listeners anticipate and make sense of complex auditory environments.
What role does selective attention play in processing pitch deviants?
It allows listeners to focus on deviations in auditory streams.
What type of brain activity is hypothesized to correspond with pupil responses to pitch deviants?
Activity in the auditory cortex associated with expectation and error detection.
How might pitch predictability influence learning in a musical context?
Predictable sequences could enhance learning by reducing cognitive load.
What does this study reveal about the nature of expectation in auditory processing?
It is an automatic, adaptive process that adjusts to the predictability of auditory input.
How could pupil responses to pitch deviants be used in educational settings?
To assess students’ auditory engagement and detect cognitive overload.
What future applications might stem from this research in understanding auditory disorders?
It could help identify deficits in auditory prediction in conditions like dyslexia or auditory processing disorders.
