| SUMMARY: | Experiments to explore the cost of task switching. The task was a stimulus of a letter and a number. On certain trials the task was to respond that the letter was either a consonant or a vowel. Then the tasks was switched to determine if the number was odd or even. They varied many parameters, such as time between response and the next stimulus, if the switch was predictable or unpredictable and which response was required for which task (crosstalk situation). They present some good verbiage on "executive processes" which control this task-set reconfiguration. In the end, they propose that this executive process is an active process that is the endogenous component of task-set reconfiguration. |
SIGNIFICANT CONCEPTS/EXCERPTS:
Notes: Not sure how this relates to CTM, as I can't think of situations where pilots switch tasks on the same stimulus Of course, they switch tasks all the time, but they are switching between tasks with different stimuli. I can't think of a situation where they switch how they respond to the same stimulus.
