(william james, 1890) Types of attention: focused or selective" attention : studied by presenting individuals with two or more stimulus inputs at the same time and instructing them to respond to only one. Question: what do we process from the unattended channel? asked to repeat ( shadow ) one of them. Cherry (1953) : how can we follow only one conversation when everyone is. Speech vs other sounds in unattended ear. Similar messages in both ears but staggered. Only crude information from the unattended ear is encoded. When voices are physically similar they are hard to distinguish (a old man vs a young girl) Words are not recognized even when repeated many times. German and english switch was not distinguishable.
