Document Summary
Tms: transcranial magnetic stimulation video: pulse- speech arrest (shuts down broca"s area interfering with the neurons firing) Errors in asl: signer must produce competing hand shapes in sequence, anticipation errors: similar to spoken language errors. Word exchange errors often don"t affect inflectional morphemes: i hoped he would like you , i liked he would hope you. Known as stranding errors: suffixes seem to stay put. Syntactic category rule: n n, v v. I parked the truck (car) in the yard: occurs frequently. I trucked the park in the yard: very rare. How do we explain these errors: not just producing one phoneme after another. Words are the same way: ordered hierarchically into many levels. Syllables are organized hierarchically: onsets, rhymes, codas. Assembling a word involves assigning phonemes to the hierarchy. As we produce speech we move from one level of organization to the next. Each step involves assembling units into a sequence.
