- Domestic guinea pigs and wild cavies were transferred from their familiar home enclosure to a novel enclosure for four hours. The absolute increase from initial values (I, in home enclosure) to values after 1 h (R1), 2 h (R2), 3 h (R3), and 4 h (R4) in the novel enclosure as well as from I to the maximal response value (MAX, maximum value of R1-R4) are shown. The responses of guinea pigs and cavies were compared during early and late adolescence. Ndomestic = 10, Nwild early = 8, Nwild late = 7. Significant p-values are highlighted in boldface.
