Scenario II
Scenario II is presents fabricated data inspired by the following study:
Greimel, E., Wanderer, S., Rothenberger, A., Herpertz-Dahlman, B., Konrad, K. & Roessner, V. (2011) . Attentional performance in children and adolescents with tic disorder and co-occurring attention-deficit/hyperactivity disorder: new insights from a 2×2 factorial design study. Journal of Abnormal Child Psychology, 39, 819-828.
Effect of Tic Disorder and ADHD on Children's Attention
This study examined the extent to which tic disorder (TD) and attention-deficit/hyperactivity disorder (ADHD) , both individually and combined, affects attention in children and adolescents. To that end, the researchers recruited children with and without TD, and children with and without ADHD. This 2 × 2 (TD × ADHD) design resulted in four conditions: children with no diagnosis (control) , children with TD only, children with ADHD only, and children with TD+ADHD. The Child Behavior Checklist (CBCL) was used to quantify three components of attentional behavior: internalizing, externalizing, and attention. The results revealed that children with ADHD+TD had significantly more internalizing than those with TD alone. In addition, children with ADHD+TD as well as children with only ADHD had more externalizing than those with TD alone. Lastly, ADHD+TD children had more attention problems than those with only TD and those with only ADHD. The results of this study suggest that children with ADHD+TD have more behavioral problems than those with single diagnoses and those with no diagnoses.
-(Scenario II) Suppose the results of Scenario II were that kids with ADHD had more behavioral problems when they did not have TD, and that kids with high TD had more behavioral problems when they did not have ADHD. This would indicate what type of relationship between the two independent variables?

A) marginal
B) hybrid
C) suppression
D) synergistic
