Rats were provided with opportunity to turn reinforcing hypothalamic stimulation on and off by traversing back and forth across a chamber. When provided with edible and inedible objects, all animals that self-stimulated carried them from the stimulation to the nonstimulation side. Neither food deprivation nor a history of stimulus-bound eating produced a preference for the edible objects. Equivalent stimulation provided without regard to the animals' location in the chamber did not elicit object-carrying. Results are interpreted in terms of the natural conditions which normally elicit this species-specific unit of behavior. Implications for understanding other behavior patterns elicited by hypothalamic stimulation are suggested.
通过在一个小室内来回穿梭，为大鼠提供了开启和关闭强化性下丘脑刺激的机会。当提供可食用和不可食用物体时，所有自我刺激的动物都会将它们从刺激区域携带到非刺激区域。食物剥夺和受刺激约束的进食史均未产生对可食用物体的偏好。无论动物在小室内的位置如何，提供同等刺激都不会引发携带物体的行为。根据通常引发这种物种特异性行为单元的自然条件对结果进行了解释。并提出了对理解下丘脑刺激引发的其他行为模式的启示。
