[Purpose and Subjects] The present investigation was conducted in order to confirm the symbolization process concerning tactile and visual object recognition in 13 healthy adults. [Methods] After three kinds of stimuli with different surfaces (smooth paper, sand paper and cloth) were presented haptically (T-task) and/or visually (V-task), all participants were asked to express as many words as possible associated with the stimulus within 3 minutes. A verbal report by semi-structured interview was recorded, and the contents of the interview were analyzed by Modified Grounded Theory Approach (M-GTA). [Results] The results show that some concepts such as "intuitive judgment", "judgment by association", "judgment by memory recall", "exploratory judgment" and "functional adherence" were created during the object recognition process in T-task and V-task, and moreover another "judgment by tactile image" in V-task. [Conclusions] These findings suggest that these classified concepts may be adopted as various strategies for retrieval and mapping of base in analogical function, that is one type of human thinking.
