Readers fixate longer on less predictable lexemes than on more predictable lexemes, but the predictability of a lexeme depends on the preceding context.
it is common for psycholinguistic models to include a measure of n-gram predictability for each fixated word conditioned on its context, but unless probabilities for words between fixations are also included, the probabilities used in this calculation are   Table 1, the standard bigram factor (top line) predicts that the reading time of the region that ends with word 6 depends on word 5, but the probability of word 5 given its context is never included in the model, so an improbable transition between words 4 and 5 would not be caught.
