Letter Matching Reaction Times

In this study participants were required to make a same/different judgement

regarding pairs of letters, that were either identical, having the same name, or different. Generally, faster reaction times were found in the identical condition, which supports the idea that we operate sequentially as those conditions that only entail one stage are faster than those which entail further stages.

Introduction.

Research into the detection of the component features of patterns helps us to see that one possible way in which objects might be identified is to decompose them into their component features & check these features against stored lists of features. This implies that we operate in a sequential & hierarchical fashion. Evidence for just this kind of sequential processing derives from the assumption that each stage of processing must take a certain amount of time. Thus identifying a feature will take less time than naming a word. If this is the case then any processing task that requires only one level or stage to be passed through should take less time than one that requires several stages, Williams, (2003).

Experimental evidence suggests
