Table 1.

Target-distracter configurations tested in Experiment 1. Notes: Each LNS and LS pair shared the same three orientations but differed in the identity of the target. The third column represents the direction of the effect observed in the data. Conditions 1 through 5, marked LNS > LS, represent cases in which the LNS search was significantly harder than the LS search as assessed by a significant main effect of condition (LNS/LS) in an ANOVA on the search times with subject, condition, and set size as factors (p < 0.05). Conditions 6 through 9 represent cases in which LNS were easier than LS searches. Condition 10 showed no significant difference.
