Fig. 4: Testing the GUT rule.
From: Differential patch-leaving behavior during probabilistic foraging in humans and gerbils
a Point plots show individual humans’ GUTs and averaged time intervals between two consecutive reward captures (i.e., inter-target intervals, ITT) in seconds (s) plotted for each patch quality of the long-GUT group. Connecting lines indicate the values that belong to the same individual. In all subjects GUT durations consistently exceeded the average ITTs, in accordance with a GUT rule used for patch-leaving. b Corresponding GUT and ICI data shown for the short-GUT group, red lines show a downward trend indicating 14 subjects who had lower GUTs than ITTs and, thus, a GUT-ITT pattern not conforming to the GUT-rule. c The point plot shows the same GUT-ITTs relation for the long-GUT gerbil; the single red line indicates the deviation from the GUT-rule in a single gerbil. d Point plots show short-GUT gerbils’ GUT-ICI patterns. Here, all animals showed data consistent with the GUT rule.
