Document Summary
Automaticity: processes that require little or no involvement of conscious, limited attention mechanisms (i. e. walking) Shneider and shiffrin visual and memory search experiments believe that processes become automatic when; When given input is systematically associated with a particular response. Memory search experiments: a fixation point is given, in which a set is shown. The fixation point is then given again, and another set is shown. Participants are expected to answer whether the second set was a part of the first; Consistent mapping: targets are always letters and distracters are always numbers. Varied mapping: one set containing only letters of number are shown. On every trail, items that are targets and distractors change. With practice, search in the consistent mapping condition should become more automatic. Scheider and shiffrin"s predictions were supported: response times were generally faster in the consistent mapping condition, progress towards automaticity occurs only the consistent mapping condition. Thus, a systematic association between input and response is important.
