Neural adaptation of imaginary visual motion.

Observers made time-to-contact judgements about an imagined moving object that passed through an area of the visual field previously adapted to a single direction of real motion. The direction of imagined motion varied relative to the direction of adapting motion. When imagined motion was in the same direction as that experienced during adaptation, imagined speed was slowed; when imagined motion was in the opposite direction, its speed was increased; when adaptation and imagined motions were orthogonal, imagined speed was unaffected. The particular influence that prior adaptation has on imagined speed suggests that imagined motion and real vision may engage common neural mechanisms without being functionally equivalent. Negative aftereffects observed in imagined motion imply that the imagination represents movement as an inference from position changes of static images.

On the role of extraretinal signals for saccade generation.

We investigated the accuracy of sequential saccadic eye movements, executed without visual feed-back. We found evidence that the final error of one saccade is corrected during the next, which supports the existence of extraretinal inputs to the saccadic generator. The corrections, however, were incomplete, which suggests that extraretinal signals are only partially effective.

Eye movements as a window into real-time spoken language comprehension in natural contexts.

When listeners follow spoken instructions to manipulate real objects, their eye movements to the objects are closely time locked to the referring words. We review five experiments showing that this time-locked characteristic of eye movements provides a detailed profile of the processes that underlie real-time spoken language comprehension. Together, the first four experiments showed that listeners immediately integrated lexical, sublexical, and prosodic information in the spoken input with information from the visual context to reduce the set of referents to the intended one. The fifth experiment demonstrated that a visual referential context affected the initial structuring of the linguistic input, eliminating even strong syntactic preferences that result in clear garden paths when the referential context is introduced linguistically. We argue that context affected the earliest moments of language processing because it was highly accessible and relevant to the behavioral goals of the listener.
