Abstract
Earlier works demonstrated that Ss utilize a "paralogic" rather than a logician's logic in constructing linear orders. In this study, the finding was inspected in a case of constructing linear order of time series. Ss received two premises specifying an order of age among three men followed by a question. The difficulty of solving a linear syllogism is measured by the percentage of Ss able to answer the question. Variations in difficulty of alternative forms of the problem were investigated. Ss received statements like Taro was born before Jiro. They were instructed to write the names in two dimensional space. Results are as follows. (1) People learn a time series more readily from past to present than form present to past within premises. (2) Relation word does not decided difficulty of solving a linear syllogism. It is decided by logical meaning. (3) Time series are tied to specific axes and directions.
