Social motivation (as measured by a visually isolated chick's tendency to establish visual contact with, move towards and remain in proximity to a group of conspecifics) was assessed in lines of Japanese quail which had been selected for high (HSR line) or low (LSR line) levels of an index of treadmill behaviour which combined the tendency to run towards conspecifics with the tendency to move away from them. HSR line chicks peeded sooner and more frequently before establishing visual contact with conspecifics and spent more time close to conspecifics after visual contact had been established than LSR line chicks. HSR line chicks also tended to have shorter latencies to establish visual contact with conspecifics, jump more and interact more with conspecifics than LSR chicks. It is suggested that these results indicate that selection for treadmill behaviour, which is considered to be a measure of social reinstatement tendencies, has influenced overall levels of social motivation. Furthermore, it would also appear that the phenotypic differences between the HSR and LSR lines are relatively intensive to genotype x environment interactions.
通过视觉隔离的雏鸡与一群同种个体建立视觉接触、朝其移动并保持接近的倾向来衡量社交动机，在日本鹌鹑品系中进行了评估。这些鹌鹑品系根据跑步机行为指数的高（HSR品系）或低（LSR品系）水平进行了选择，该指数综合了朝同种个体奔跑的倾向和远离它们的倾向。与LSR品系雏鸡相比，HSR品系雏鸡在与同种个体建立视觉接触之前更快且更频繁地发出叫声，并且在建立视觉接触后花更多时间靠近同种个体。HSR品系雏鸡与同种个体建立视觉接触的潜伏期也往往更短，比LSR雏鸡跳得更多且与同种个体互动更多。研究表明，这些结果表明，对跑步机行为的选择（被认为是社交恢复倾向的一种衡量）影响了社交动机的总体水平。此外，HSR和LSR品系之间的表型差异似乎也相对强烈地受到基因型×环境相互作用的影响。
