Auditory Perception & Speech Processing

← Back to Domain-Specific Families

Abstractions about how sound and speech are perceived, remembered, and reproduced — perceptual effects like phonemic restoration and repetition blindness, memory and acquisition processes such as rehearsal, speech repetition, and language acquisition, and technical or notational systems like colored music notation and sound recording.

9 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Colored music notation — Colored music notation is a technique used to facilitate enhanced learning in young music students by adding visual color to written musical notation.
• Irrelevant speech effect — The finding that serial recall of verbal material is impaired by to-be-ignored background speech — even foreign or reversed — because changing-state speech-like sound gains obligatory, pre-attentive access to the phonological store and competes with the subvocally rehearsed task codes.
• Language acquisition — Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language.
• Memory Rehearsal — Maintenance rehearsal is viewed in educational psychology as an ineffective way of getting information to the long-term memory.
• Phonemic restoration effect — Phonemic restoration effect is a perceptual phenomenon where under certain conditions, sounds actually missing from a speech signal can be restored by the brain and may appear to be heard.
• Repetition Blindness — Repetition blindness (RB) is a phenomenon observed in rapid serial visual presentation.
• Sign Stimulus — Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign/key stimulus or releaser.
• Sound Recording and Reproduction — Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects.
• Speech repetition — The automatic nature of speech repetition was noted by Carl Wernicke, the late nineteenth century neurologist, who observed that "The primary speech movements, enacted before the development of consciousness, are reflexive and mimicking in nature..".
