 In this report, we investigated the visual recognition of pictograms among university students. The subjects were 24 university students (mean age:21.8±0.6 years) without history of brain injury. A total of 151 pictograms were randomly displayed on a screen, and the subjects verbally expressed their interpretation. The overall average rate of correct answers was 65.9%, whereas that of incorrect answers was the highest at 8.7%. The pictograms are set to four levels of recommendation, namely, A, B, C, and reference. Recommendation levels of A and B are considered particularly necessary for a large number of users. However, each of them included approximately 10〜20% of items with a correct response rate of less than 60%. In addition, no statistically significant difference was observed for the percentage of correct responses and degree of recommendation. It seems that correct interpretation of pictograms requires not only the basic visual cognitive ability but also multiple information processing from other higher brain functions such as visual attention, memory, and executive function. Finally, we think it is necessary to explore the visual mechanism for categorization and extraction of meaning.
