title: [Cognition of binary-event-sequences: its relation to the sequential attributes].
abstract: Sixty subjects were asked to evaluate the degree of similarity among 15 binary-event-sequences which were generated through the Bernoulli process. The averaged similarity matrix of 50 subjects (ten omitted) was analysed by the Hayashi's Quantification Method IV, and the dimensions yielded were compared with the theoretically derived dimensions for the operational interpretation. The result showed that the run structure--the number of runs and the length of the longest run--and the number of one event in a sequence were the important attributes in cognition of binary-event-sequences. These attributes were most frequently employed by subjects, although other attributes and their combinations may be relevant. It was pointed out that the general tendency of judgments, i.e., dependence on the spatial and visual aspects of given sequences, proved subjects' inattention to the characteristics of the probabilistic generation process of sequences.
