Table 4. Type-I sequential ANOVA’s eta-squared (N = 924) contrasting the effect of the number of media simultaneously used (Mi) versus the MMI.

Model 1 Model 2
Dependent variables Sample Mi MMI MMI Mi
Attention problems 0.01 0.05 0.01 0.06 0
Motor impulsiveness 0.02 0.10 0 0.09 0.01
Sensation seeking 0.03 0.12 0.01 0.10 0.03
GradCPT d’ 0 0.09 0.01 0.07 0.03

Note. Model 1 : DV ~ Sample + Mi + MMI. Model 2 : DV ~ Sample + MMI + Mi. First column shows the dependent variables (DV). Since Sample is placed in first position in both hierarchical models, we reported one common column for the Sample effect. The other columns show the explained variance of the specified DVs for Model 1 and Model 2. Mi = media multitasking index without the hours component; MMI = Media Multitasking Index; GradCPT = Gradual-onset Continuous Performance Task.
