Wrap-up effects in reading have traditionally been thought to reflect increased processing associated with intra- and inter-clause integration (; ; cf. ). We report an eye-tracking experiment with a strong manipulation of integrative complexity at a critical word that was either sentence-final, ended a comma-marked clause, or was not comma marked. Although both complexity and punctuation each had reliable effects, they did not interact in any eye-movement measure. These results and simulations using the E-Z Reader model of eye-movement control () suggest that traditional accounts of clause wrap-up are incomplete.
