It is shown that dynamics of percentage of conditioned food refusals by snails Helix pomatia and Helix lucorum is satisfactorily approximated by regression equation of exponential type with included coefficient reflecting the animals state before the beginning of learning. The ability is established of the snails to practically completely differentiate various alimentary conditioned stimuli. The introduction of differentiation always improved the reflex consolidation. Conditioned reactions to differentiation stimulus appeared at the elaboration stage and were absent at the stage of conditioned reflex consolidation.
结果表明，罗马蜗牛和白玉蜗牛对条件性食物拒绝的百分比动态，通过指数类型的回归方程能够得到令人满意的近似，该方程包含反映学习开始前动物状态的系数。已确定蜗牛实际上能够完全区分各种食物性条件刺激。引入分化总是能改善反射巩固。对分化刺激的条件反应在细化阶段出现，而在条件反射巩固阶段则不存在。
