I do not agree with the fact that humans are very similar to the functionality of machines. Although machines are able to improve with greater technology, they are mostly consistant with every result. Humans fluctuate on trials because we are not able to generate the same amount of focus every time, or we have an "unlucky" round. A machine, will consistantly produce the same results, whereas a human can improve over time. You can try to mimic the same characteristics on a "good" round, but you will never be able to exactly replicate a previous trial.
I agree with your assessment discrediting the validity of the human to machine comparison. Machines are what their name states: mechanical. They have a certain consistent way of performing a task that yields a certain set of consistent results. In my experience with this lab, the results varied, sometimes very greatly, when compared with each other. My left hand and right hand do not perform the task of catching the ruler in a similar way. Likewise, when separate parts of the experience were concentrated upon, different results were yielded. A machine does not exhibit this variety in its performance of an activity, and it certainly does not possess the capacity to focus its attention on different parts of a task.
