Japanese quail (Coturnix coturnix japonica) were selected over 8 generations for long or short duration of tonic immobility (TI) weighted for independence from social reinstatement (SR) behavior (as measured in a treadmill) and for high or low levels of SR behavior weighted for independence from duration of TI. Divergent selection for long or short duration of TI and for high or low levels of SR behavior resulted in immediate and significant responses that continued throughout the 8 generations. There was no evidence of a plateau in the response to selection in any of the lines. SR responses did not vary in lines selected for duration of TI and vice versa. Selection for short duration of TI led to in an increase in the number of inductions required to induce TI. Selection for low levels of SR behavior led to a decrease in the tendency to move toward conspecifics but not to an increase in the tendency to move away from conspecifics.
日本鹌鹑（Coturnix coturnix japonica）经过8代选育，针对强直静止（TI）的持续时间进行长短选育，该选育基于与社会恢复（SR）行为（在跑步机上测量）的独立性加权；同时针对SR行为的高低水平进行选育，该选育基于与TI持续时间的独立性加权。对TI持续时间的长短以及SR行为的高低水平进行的分化选择导致了即时且显著的反应，这种反应在整个8代中持续存在。在任何品系中，均未发现对选择的反应出现平台期的证据。在针对TI持续时间进行选育的品系中，SR反应没有变化，反之亦然。对TI短持续时间的选育导致诱导TI所需的诱导次数增加。对低水平SR行为的选育导致向同种个体移动的倾向降低，但并未导致远离同种个体的倾向增加。
