Additionally, there was a marginally significant congruency × experiment effect ( F ( 1 , 82 ) = 3.65 , p = 0.059 , η p 2 = 0.04 ), which indicated a marginally weaker congruency effect in Experiment 1 compared to Experiment 2 .
As found for incongruent-same trials, the alignment × experiment interaction failed to reach at least marginal significance ( F (1,82) = 2.63, p = 0.109), which means that flatter alignment slopes of incongruent trials in Experiment 2 compared to Experiment 1 could not be confirmed at any significance level with the given sample size, neither with incongruent-same trials (see Fig. 6 ), nor with all incongruent trials (see Figs. 4 and 5 ).
