Varied manipulatory-gnawing experience with nonfood objects facilitated later nut opening and insect predation in rats. Varied food consumption, which minimized manipulation, facilitated the hulling and consumption of sunflower seeds. Both treatments weakly facilitated forepaw food tablet grasping but neither treatment altered novel foods consumption or nest building. The data suggest that these two forms of prior experience contribute differentially to some later behaviours depending upon the sensory-motoric demands of the task and/or upon the intensity of food related stimulation.
对非食物物体进行多样化的操控啃咬体验，有助于大鼠日后打开坚果和捕食昆虫。多样化的食物消耗（将操控行为降至最低），有助于去壳和食用向日葵种子。两种处理方式都对前爪抓取食物片有微弱的促进作用，但两种处理方式都没有改变对新食物的消耗或筑巢行为。数据表明，这两种先前的经验形式，根据任务的感觉运动需求和/或与食物相关的刺激强度，对一些后续行为的贡献有所不同。
