Human Response Times in Learned and Unlearned Cues INTRODUCTION There are many structures and functions of the human body. There are also many processes included in everything we do such as to sending the message from your brain to stomach that you are hungry to eating and digesting of food. There are always messages being sent, received, and processed. One way that messages are sent are via neurons. Neurons are cells in the nervous system that transmit information to other nerve cells, muscles, or glands within the body. Sensory neurons are responsible for turning external stimuli from the environment into internal electrical impulses. These neurons respond to stimuli such as hot, cold, sharp, and loud noise. These sensory neurons then…show more content…
This lab will alter a previously learned response, the catching of a falling ruler in an attempt to enhance the sense of unlearned higher information processing. According to Lutterschmidt, “if this experiment is repeated enough times, then the unlearned response will eventually become a learned response.” However, the processes within the experiment were only repeated for a total of three trials. Therefore, it is thought that there were no significant differences observed between the learned and unlearned response times. MATERIALS AND METHODS The procedure took place in the physiology lab at the University of Texas at Tyler, on February 14, 2017 at approximately 2-5 p.m. The materials used for the lab included a ruler and 3 test subjects. The first part of the procedure tested learned response times using a visual cue. This was done by suspending a ruler just above a subject’s outstretched thumb and index finger. The subject visually observed the ruler while in the outstretched position, the ruler was then released and the subject caught the ruler as it fell between the thumb and index finger. The measurement of the ruler where it was caught was rounded to 0.5 cm and recorded. This procedure was repeated three times, data was recorded onto a table. The next part of the procedure measured learned response times using an auditory cue. The same procedure used for learned response times using a visual cue, was used here. During this procedure, the subject kept their
