This paper focuses on the optimum use of representational space by words in speech and in the mental lexicon. In order to do this we draw the concept of entropy from information theory and use it to plot the information contour of words. We compare different representations of Spanish speech: a citation vs. a fast-speech transcription of a speech corpus and a dictionary lexicon vs. a speech lexicon. We also compare the information profiles yielded by the speech corpus vs. that of the speech lexicon in order to contrast the representation of words over two representational spaces: time and storage space in the brain. Finally we discuss the implications for the mental lexicon and interpret the analyses we present as evidence for a version of Butterworth's (1983) Full Listing Hypothesis.
