Trying to accomplish two or more tasks at the same time. (doing this people strain the limit of attention, the limits of working memory and long term memory)
Multi task
What are the four kinds of Selective attention tasks
Dichotic Listening
The Stroop Effect
Visual Search
Sarccadic Eye Movement
A laboratory technique in which one message is presented to the left ear and a different message is presented to the right ear. (used to investigate Selective attention)
