1.  A goal-based perspective on eye movements in visual world studies 
Acta psychologica  2010;137(2):172-180.
There is an emerging literature on visual search in natural tasks suggesting that task-relevant goals account for a remarkably high proportion of saccades, including anticipatory eye-movements. Moreover, factors such as “visual saliency” that otherwise affect fixations become less important when they are bound to objects that are not relevant to the task at hand. We briefly review this literature and discuss the implications for task-based variants of the visual world paradigm. We argue that the results and their likely interpretation may profoundly affect the “linking hypothesis” between language processing and the location and timing of fixations in task-based visual world studies. We outline a goal-based linking hypothesis and discuss some of the implications for how we conduct visual world studies, including how we interpret and analyze the data. Finally, we outline some avenues of research, including examples of some classes of experiments that might prove fruitful for evaluating the effects of goals in visual world experiments and the viability of a goal-based linking hypothesis.
