This study explored the interaction between three individual variables, need for cognition and tolerance of ambiguity, and the symbol system used in messages. Goodman's (1976) dimension of notationality of systems is proposed as the continuum of interest upon which sources of information vary. It was hypothesized that high tolerance for ambiguity and need for cognition would lead to increased numbers of interpretations of nonnotational messages over notational ones, and over people low in these traits. Methods utilized in the study are overviewed. Results indicate that subjects high in need for cognition do generate more interpretations of messages in general than do others, however no effect was found for ambiguity tolerance or for message type. Reasons for these results are offered, and directions for further research suggested.

Relationships between reading and writing -- Formation of a thought-world that is a cluster of ideas and associations related to a literacy event -- Establishment of a progression of interrelated ideas from the thought-world -- Creation of intersentence cohesion by filling of gaps.
