When the light was shone in the right eye, the left pupil constricted in response. The response did not change from that of the stimulated right eye.
Based on my observations, the pupil reflex is both an ipsilateral reflex and contralateral reflex.
If a person’s left pupil is dilated more than his right pupil, he may have Anisocoria, a harmless condition characterized by unequally sized pupils affecting about 20% of the population.
Having the subject close their eyes during the patellar tendon reflex amplified the response to the mallet strike by causing distraction so that the person was unable to voluntarily suppress the reflex.
Although reflexes do not require the activation of higher brain centers, they can be voluntarily inhibited because even at the simplest level, there are multiple inhibitory influences that can affect the excitability of the motor neuron. …show more content…
6.2: Learned and Unlearned Responses
The null hypothesis is that there is no difference between the response distances of learned and unlearned responses. Since the p-value, 0.04, is less than 0.05, I would reject the null hypothesis. As the level of information processing increases, the response time increases because completing the reaction would take much more time if higher brain processing were required. I do see a difference in the response time when using a learned visual cue versus a learned auditory cue because the human brain generates a response to visual stimuli faster than auditory stimuli.
I would expect to see a difference between the response times of these unlearned and learned responses if I performed 25 trials for each test because eventually the subject would learn the unlearned responses and they will be able to respond faster to
