a suggestive trendp = 0.052
Indeed, in control conditions there is a suggestive trend for a decline in sociability over time (effect of trial = −65.03 ± 31.45, F 1,19 = 4.28, p = 0.052) whereas fish measured under the risk context exhibit no such habituation (effect of trial = −37.8 ± 32.6, F 1,19 = 1.34, p = 0.26).
