The representations that underlie our ability to read must encode not only the identities of the letters in a word, but also their relative positions. In recent years, many new proposals have been advanced concerning the representation of letter position in reading, but the available data do not distinguish among the competing proposals; multiple theories, each positing a different letter position representation scheme, are compatible with the evidence. In this article, we report two experiments that used the illusory word paradigm (e.g., Davis & Bowers, Journal of Experimental Psychology: Human Perception and Performance, 30: 923–941, 2004) to distinguish among alternative schemes for representing letter position in reading. The results support a scheme that uses both the beginning and the end of a word as anchoring points. This both-edges scheme has been implicated in letter position representation in …
