only marginally significantP = 0.061
However, increased switch-cost in control conditions (tested with one-sample t -tests against constant value 0 for ΔLA) was only marginally significant for the late afternoon sessions [+1.81 ± 4.28, t (21) = 1.981; P = 0.061; d = 0.42] and decreased switch-cost failed to reach statistical significance after both interventions [-0.71 ± 3.36, t (21) = -0.996; P = 0.331; d = 0.21].
