A 5-yr-old mentally retarded spina bifida child was taught to walk with the aid of crutches. This behavior was developed through fading of physical prompting within a 10-step successive approximation sequence. Preliminary training to establish gait consisted of developing use of parallel bars through fading of physically modelled responses within a six-step successive approximation sequence. Use of parallel bars ceased during an extinction period and completely recovered upon being primed with one "free" reinforcement. Systematic use of natural reinforcers was employed as an aid in maintaining use of crutches.
一个 5 岁的智力迟钝的脊柱裂儿童在拐杖的帮助下被教导行走。这种行为是通过在 10 步连续逼近序列中逐渐减少身体提示而发展起来的。初步的步态训练包括通过在 6 步连续逼近序列中逐渐减少物理模型反应来建立使用平行杠。在一个消退期间停止使用平行杠，并在一个“自由”强化物的启动下完全恢复。系统地使用自然强化物作为维持使用拐杖的辅助手段。
