LIN 401 Lecture Notes - Lecture 21: Short-Term Memory, Parsing, Phoneme
Document Summary
Begins with an auditory signal (spoken languages) or a visual. Type of sound - comes from the distribution of formats (levels of acoustic. Intensity (loudness) - loud or soft frequency where the signal is concentrated). The brain matches parts of the signal to phonemes and larger units (morphemes, words, syntactic constituents, intonation, stress, emotion, etc. ) Language needs to be interpreted by the human brain. Surrounding sounds exert influences - not every pronunciation of every phoneme is always the same. The brain always rounds up to the nearest phoneme. Categorical perception exactly like the prototypical case of that phoneme. This accounts for why we hear all sets of [b]-like sounds as the same thing. Anything within the abstract space of a phoneme sounds. Lexical search occur when the word is very common. Abstract spaces in which everything sounds the same. How words are stored; how we access their meanings. Brain searches for matching words; faster correct answers of yes .
