  1. aIn the repeated measurements ANOVA for BAI the Interaction effect was: (F[1.45, 3.13], p = 0.229), Group effect: BAI (F[0.57, 2], p = 0.569) and Time effect: BAI (F[32.66, 1.56], p < 0.001)
  2. bIn the repeated measurements ANOVA for ISI the Interaction effect was: (F[2.27, 3.94], p = 0.065), Group effect: F[0.95, 2], p = 0.392) and Time effect: BAI (F[18.06, 1.97], p < 0.001)
