This piece is a commentary on a Behavioral and Brain Sciences target article by Robert Wilensky entitled: Story grammars vs story points.

In spite of the growing interest witnessed in the study of the relationship between emotion and language, the determination of the emotional valence of sentences, paragraphs or texts has so far attracted little attention. To bridge this gap, a technique based on the emotional aspect of words is presented. In this preliminary study, we have compared the affective tones of the sentences of four texts as perceived by readers, to the values generated by the words that compose the texts. The (...) results support the psychological reality of the affective tones of linguistic units larger than a word, and the possibility of their evaluation through the lexical information. Such information should be. useful for studying the role of emotional interest on text processing and for the analysis of the natural stories produced by people in reaction to stressful events.
