摘要：This paper reports preliminary analyses of mouse tracking to investigate on-line syntactic processing in aphasie patients. Mouse tracking is a relatively new task that has proven valuable in the study of syntactic processing in normals; e.g., Spivey et al. (2005) used it to study ambiguity resolution in PP attachments, yielding unique information about the time course and nature of eflècts of distracters in the real world paradigm. It consists of measuring mouse movements while participants make responses to spoken sentences in a task. Its temporal resolution is higher than eye tracking, because it measures positions of continuous ballistic movements at 40 msec intervals, while eye tracking is limited by the frequency of saccades.
