Document Summary
Speech brand of psychology devoted to study verbal behaviour. Psycholinguistics: branch of psychology devoted to study verbal behaviour. Speech is social, it is learned and used in interaction with others. We extract words from a stream of speech. Our auditory systems recognize patterns underlying speech. Belin, zatorre, and ahad: used fmri scans to find that some regions of the brain responded more to human vocalizations rather than just other natural sounds. Left hemisphere showed larger contrast and thus, it plays a larger role in analyzing speech. Eg: pin is three phonemes /p/+/i/+/n/ : voice-onset time: a way in which we discriminate among phonemes. It is the delay between the initial consonant sound and vibrating vocal chords (voicing). Eg: there is a delay in voicing for pa compared to ba although the initial sound (made with the mouth) is the same: phonemic discriminations initially occur in both hemispheres. We recognize speech sounds in larger chunks such as syllables.
