Real-time language comprehension research using the Apple-Psych system.

We describe the use of the Apple-Psych system to conduct language comprehension experiments. Using this system, we have implemented several tasks commonly used to assess the cognitive processes involved in language comprehension. These include segment-by-segment reading tasks in which the stimuli are presented visually, and divided-attention and crossmodal tasks in which the stimuli are presented both visually and auditorily. Currently we are using the system to control collection of event-related potentials while subjects comprehend auditory discourse.
