Figure 3. Behavioral variability in the frog. A. Base line behavior. On each of ten trials, the frog was positioned at the lower cross (long vertical line is body axis, short horizontal line the line between the frog's eyes) and presented with a live mealworm confined in a cup (short upper horizontal line.Thinner oblique lines show the position and angle of the frog's head after the first movement on each trial. Notice that both position and angle vary substantially. B. Reduction of stimulus cup size (shorter upper horizontal line). Notice that there is no corresponding reduction in the variability of final head position. C. Increase in variability of initial posture (broadening of line corresponding to body axis). Notice that there is no corresponding increase in the variability of final head position. D. A richer visual environment. Notice that, under this condition, the observed variability in final head position significantly decreases. Unpublished studies by Paul Grobstein, Jeff Oristaglio, and others.
