An apparatus was developed to study social reinforcement in the rat. Four Long-Evans female rats were trained to press a lever via shaping, with the reinforcer being access to a castrated male rat. Responding under a fixed-ratio schedule and in extinction was also observed. Social access was found to be an effective reinforcer. When social reinforcement was compared with food reinforcement under similar conditions of deprivation and reinforcer duration, no significant differences were observed.
开发了一种装置来研究大鼠的社会强化作用。通过塑造训练了四只长 Evans 雌性大鼠按压杠杆,强化物是与一只阉割过的雄性大鼠接触。还观察了在固定比率时间表下的反应以及消退情况。发现社会接触是一种有效的强化物。当在类似的剥夺和强化物持续时间条件下将社会强化与食物强化进行比较时,未观察到显著差异。
