This is when a person is able to complete their program very quickly and doesn't have the cognitive aspect involved in the response to the stimulus. At this time the plateau occurred and the data remained at that level for the remainder of the trials. Some of the learning that could have been involved with the improvement of the scores could have been due to the automatic processing that took place in the later trials. People knew what they needed to do and would simply wait for the stimulus to start the motor response. Norrie also showed that the improvement for simple reaction tasks will occur early in the practice and that improvement will not continue to occur throughout all of the practice trials.
Henry talks about learning with respect to the neuromotor coordination.
Neuromotor coordination is achieved by the controlled processing of information moving to the automatic processing. The muscles have acted out the program that had been learned without the individual cognitively thinking about the process. This is a movement that allows people to simply react to a stimulus. This type of learned information can be possibly seen in our data. The experiment shows that a plateau occurs with the data and the possibility for the plateau is because the response to the stimulus has become more automatic.
