1. (A–F) Histograms showing the recruitment of dance-followers.
(A–F) Histograms showing the recruitment of dance-followers. Each part of the figure represents the results from a single sector, indicated in the inset. Each column in each figure shows the number of dance-followers that turned their heads and ran in to follow the dancer. The distance from which they came is indicated along the abscissa. The data were analysed into 5 mm ‘bin widths’ because this represents the approximate width of a single cell. The distance is, nevertheless, given here as ‘cell widths’ to simplify comparison with the previous figures. (A). Sector 1. Most of the dance-followers in this sector are attracted from a distance of 2–3 cells away. N=34. (B). Sector 2. The attraction in the 30–60° sector is less narrow than that in the 0–30° sector, and dance-followers come from distances of 2–5 cells away. N=30. (C). Sector 3. Recruitment of dance-followers in this sector is also broadly distributed over distances ranging from three to five cells. N=30. (D,E). Sectors 4 and 5. Dance-followers in these two sectors are recruited predominantly from the 2–4 cell distance. N=30 (D), N=22 (E). (F). Sector 6. Most of the dance-followers in this sector are recruited from close behind the dancer, suggesting the presence of an attractant in addition to, or in place of, substratum vibratory signals. N=28. The line parallel to the x axis indicates the range over which phase reversal would be expected to occur.
