Taking into account the study of Luegi (2006), where eye movements of 20 Portuguese
university students while reading text passages were analyzed, in this article we discuss
some methodological issues concerning eye tracking measures to evaluate reading
difficulties. Relating syntactic complexity, grammaticality and ambiguity to eye
movements, we will discuss the use of many different dependent variables that indicate the
immediate and delayed processes in text processing. We propose a new measure that we
called Progression-Path which permits analyzing, in the critical region, what happens when
the reader proceeds on the sentence instead of going backwards to solve a problem that s/he
found (which is the most common expected behavior but not the only one, as is illustrated
by some of our examples).info:eu-repo/semantics/publishedVersio
