Auditory Stream Analysis and Gestalt Principles

These flashcards cover key concepts related to auditory streams, Gestalt principles, and the processes involved in auditory scene analysis.

Auditory Streams

The purpose of hearing to identify sound sources and discern which sounds belong together.

Auditory Scene Analysis

The process by which we distinguish different sounds, even in complex contexts, by breaking them down by frequency.

Gestalt Principles

Descriptive generalizations about how perception is organized, highlighting that the whole is different from the sum of its parts.

Proximity (Hearing)

In auditory perception, sounds that are close in pitch and/or time are perceived as parts of the same auditory object.

Similarity (Hearing)

Sounds that have similar timbre are perceived as belonging together.

Good Continuation

The principle that listeners perceive smoothly connected pitches as a single stream, rather than as abrupt changes.

Common Fate

Items that move together in pitch are perceived as parts of the same perceptual entity.

Old-plus-New Heuristic

The tendency to interpret a sudden increase in complexity as the addition of a new sound to an ongoing sound.

Continuity in Audition

The perception of an old sound being continuous with a new sound, despite interruptions.

Pitch Proximity and Tempo

As tempo increases, the tendency for streams to separate increases, potentially overridden by pitch proximity.

Testing Gestalt Principles

Creating scenarios where Gestalt principles predict interpretations, revealing conflicts that may lead to auditory illusions.

Continuity via Trajectory

Perceptual effects that arise based on the trajectory of sound, affecting pitch perception based on the gaps in sound.
