| Abstract: | The Posner paradigm has often been used to examine the allocation of attention. Van der Heijden (1992) reasoned that participants may use a probability matching when cue validity is less than 100%. In this study, a cue validity of 66% and 100% was used to examine how participants allocate their attention with different cue validities. This was examined with event related lateralizations (ERL). A comparison of the validly cued trials showed no differences in reaction times and percentages of correct responses between the two conditions. However, ERL analyses revealed an effects above an occipito-parietal site. The latter results suggest that participants may indeed use a probability matching strategy. |
