• time-sharing efficiently allocation processing resources to component task at appropriate times
• advance reconfiguration intentionally prepare for a task switch, thus eliminating costs of having to change tasks
• switching costs increases in RT and error rates on the task after switch
• mixture distribution distribution of responses is assumed to reflect combined result of two different underlying processes
• prospective memory remembering to perform an act in future
• procedural frame hypothesis task goals provide framework into which means to accomplish a task are assimilated to perform mental activities knowing what one needs to do provides a framework for more quickly processing particular information
• psychological refractory period effect slowing in RT to second stimulus when time interval between two stimuli is short first stimulus has an inhibitory effect on processing of the second stimulus limitation in ability to perofrm two tasks at once, implying instead that at least some processes may be carried out for only one task at a time
• response-selection bottleneck Model reponse selection can only occur for one task at a time  but stimuli for two tasks can be processed in parallel but respones to task 2 could not occur until response to task1 had been selected
