Document Summary

One voice talks really slow, one really fast at same time. Automatic processing also assists us in our ability to have divided attention. The ability to perform more than one activity at a time. Sat participants in front of a video screen and tested their reaction times in response to images that sped from the background. Significantly faster reaction times for images that were coming towards their head compared to images that would just miss their head. Participants can usually repeat the one message successfully. However, they generally have a very difficult time remembering the other message. Shadowing experiments demonstrate that we cannot attend completely to more than one thing at a time. But we can shift our attention rapidly back and forth between the messages. Perceptions have an organization and a structure- gestalt princliples. We tend to organize stimuli into a central or foreground figure and a background.
