q2 i? Additional distractors on the screen had negative consequences for children's tracking performance but less so for adults, even when tracking a single target. → Kimiko Ryokai 2013

Accuracy was analyzed as a function of target and distractor number (Fig. 5) for both children and adults. The article also reports that for children the presence of an additional distractor affected tracking 3 targets by 6% while adults showed a fixed performance level.

"for children, tracking a single target with 2 versus 3 distractors on the screen, reduced performance by 20 %, but dropped performance by only 10 % for adults."

Discussion¶

Learner Variables¶

• Attention — predictor: learners who differ on it differ in outcomes
