How Did The Jendrassik Maneuver Increased Reaction Time?
When observing our individual, we observed that that the Jendrassik maneuver increased reaction time. We believe this is so because it acts as a distraction due to the individual concentrating on the maneuver. This tells us that even though simple reflexes don’t directly involve the brain, the brain does still have influence on simple reflexes.
Reflexes can be an indication of nervous system health. When the reflexes are not acting properly or are absent, it can tell a physician if there may be a problem with the nervous system or in the region of nerves. Testing reflexes can tell a physician if something is wrong before the patient shows other noticeable signs of nervous system damage.

Pupillary light reflex protects the internal parts of the eye that are can be damaged with intense light. Constricting allow less light to penetrate the eyes.
No, the mean reaction times varied between all of the conditions set. Our results showed distraction with the greatest mean reaction time and warning with the least reaction time.
Distractions, randomness, and sound increased reaction time. Giving a warning and regular visual cues decreased the reaction time. Yes. The eye and the ears have different modes of transmission of information to the brain. The eyes uses photoreceptors (rod and cone cells) that are stimulated by image and light that has traveled into the eye. The photoreceptors synapse with ganglion cells that become the optic nerve. The optic nerve then sends the image information to the brain for processing. For the ear, the sound waves enter the auditory canal, the eardrum vibrates, the bones of the ear then amplify the vibrations, which then causes pressure waves that vibrate the basilar membrane. The basilar membrane then moves and small hairs bend which causes the stimulus for the hair cells to open ions channels that then result in the release of neurotransmitters, which stimulate afferent neurons. The brain then interprets the auditory signal. From our results we observed that auditory reaction time is greater than visual reaction time. We believe the transmission and processing from the brain may have an influence on this
