本研究以功能分析來瞭解一位多重障礙學童舔手指與遮眼睛固著行為的原因。共有兩個子研究。研究一，旨在使用類似功能分析（analogue functional analysis）來檢測該學童的兩種固著行為是由於逃避工作的要求、引起他人的注意、或是自我感官的刺激所引發。研究二，進一步地以感官的功能分析，分別來檢測該學童的兩種固著行為是由於視覺、聽覺、或觸覺的感官後果所造成的。研究結果顯示，該學童舔手指的固著行為可能是由感官的增強所形成，特別是有可能由特定的觸覺刺激所造成的；在另一方面，經兩個子研究的分析後，該學童遮眼睛固著行為的原因，仍不清楚。最後，研究者並對未來的研究提供進一步地建議。

The current study included two experiments that functionally analyzed stereotypical behaviors. An analogue functional analysis was used in Experiment 1 to detect the function of one student's stereotypical licking fingers and covering eyes which might serve to escape from task demands, obtain attention from others, or produce sensory self-stimulation. An analysis of sensory modalities was conducted in Experiment 2 to further analyze the possible sensory consequences causing this student's this student's stereot6ypies. Results of the present study demonstrated sensory sources of reinforcement were a determinant of finger-licking stereotypical behavior in this student. The specific sensory function of his licking stereotypy may be maintained by tactile stimulation. In contrast, no definite reinforcing source was identified in his eye-covering stereotypy. Finally, some suggestions for future researches were provided.
