A distinction was made between the 7 trials that had only onevoltage violation and the 6 trials that had more than one voltage violation. This examinedwhether the predictions <strong>of</strong> visual search models held true for different levels <strong>of</strong> task complexityfor the acknowledging task. In particular, response times were analyzed using a 3 (Group:Tabular vs. One-line vs. Contour) X 2 (Violation: Single vs. Multiple) Analysis <strong>of</strong> Variance(ANOVA). Scheffe post-hoc tests were conducted to explore significant differences acrossgroups.The results <strong>of</strong> the analysis revealed a significant main effect <strong>of</strong> display group,F (2,25) =9.70, p
