During the screening section of Gagliano's experiment, the pea seedlings had been placed in various Y-pipes and exposed to the fan by itself. Their path of progress was subsequently recorded. The 'appropriate' response by the seedlings was considered to get growing into the arm where the light was "predicted" from the preceding day. The majority of vegetation in both experimental situations grew within a direction consistent with the predicted location of light determined by the position on the lover the earlier day.
