Letter substitution has been shown to have a cost to word recognition performance, such as increased reaction time. The use of orthographically similar numbers or symbols as a substitute for letters is known as LEET. Perea, Duñabeitia, and Carreiras (2008) showed that word recognition was not affected when LEET substitutions were used as primes.

This study examined if visual search performance would be influenced by distracters that affect a dimension irrelevant from the task. In Experiment 1 within the letter string of a letter search task, target letters were embedded within a word.

Previous research has shown that older adults are able to compensate for age-related changes though a highly practiced skill (Salthouse, 1984 , Journal of Experimental Psychology: General, 113, 345-371). The authors examined if older adults would show a lexical-only parafoveal benefit.

Hypothesis 1 predicted that the response code compatibility effect in both experiments would benefit older adults comparably to younger adults. Hypothesis 2 predicted that stimulus-stimulus compatibility would be additive to the effects of cross-task compatibility.
