High degree of inter-experimenter reliability is dependent on sufficient training. (A). The % difference in total exploration in seconds was scored by a novice and a trained experimenter (circles, open bars) when scoring identical movies of the same subjects vs the % difference between 2 trained experimenters also scoring identical movies (triangles, closed bars. % difference = [ABS value (trained-novice)/trained %100] or [ABS value (trained1-trained2)/trained2 %100] (B) The Pass/Fail Rate for a novice vs a trained experimenter (left panel) and for 2 trained experimenters (right panel). N for each condition is shown in panel A as individual points in and within the bars in panel B. Note – the trained and novice in panel A and viewed the same movies as did the trained experimenters. The two trained experimenter in panel B viewed identical movies for each comparison, but these experiments were conducted separately, hence the different sample size.
