We wanted to measure learning and reinforcement in the flies for eight genotypes that we have tested as of now. For calculating the reinforcement scores we took the average of the two training periods combined PI scores and then subtract the PI value of the pretest period.

Reinforcement = average (combined training PI) – (combined pretest PI)

Below is the boxplot of the effect size for each fly for all these genotypes:-

We then calculated the mean of these reinforcement values for each of the screens and below is a bargraph for these means:-
