Dichotic listening: two messages presented simultaneously in different ears. Listen to one- shadowing the message: phrase and phonemic shadowing. Broadbent and the filter metaphor first proposed model of attention early proponent of information theory. Yes, right ear dominence: language processing is in the left side of the brain (contralateral) Broad(cid:271)e(cid:374)t"s earl(cid:455)-selection model: attended speech sensory buffer attentional selection semantic analysis . But: sensory buffer blocks out everything but attended speech. Can we process the meaning of words. Intermediate-selection model: activation threshold for own name, attended speech, etc, uncommon words (marsupial) have a high. Physiological evidence for early attentional selection of speech inputs. Modulation of n! by attention occurs early (within 150 ms: how can this happen attending to speech activates parietal and frontal cortex.
