Reaction time of visual response

Reaction time of optic reparteeData accretion and ProcessingIn this look into, the reception time of visual and haptic response has been investigated by measuring how both great deals reacted when eye were open and past when eyes were closed. For a better comparison of the two, the averages see been comp ard as well. The conventions centimetres swallow been turned into time counted in seconds using the formulaObservationsThe tactile responses where swift to visual stimuli presentedAs time passed, the reflexes where becoming reasonably slower, however, at both(prenominal) point, it was easy to expect when the other student would let go of the ruler imputable to the many trials.Using the measurements obtained from the above tables, graphs nurture been organised so as to better comprehend the outcomes of this experiment.ObservationsIn general, the right hand seems to ache a meteoric response to tactile stimulation than visual one. many values seem to not comply with the stop of them, probably due to the existence of other circumstanceors affecting the outcome of the experiment.ObservationsIn general, the left hand seems to have a faster response to visual stimulation than tactile one.Some values seem to not comply again with the rest of them, probably due to the existence of other factors affecting the outcome of the experiment.Overall, the tactile responses seem to be faster than the visual ones, dependent nevertheless from factors such as left-handedness and/or right-handedness.ObservationsThe left hand had a faster response to the visual stimuli compared to the right handObservationsThe right hand had a faster response to tactile stimuli than the left hand. Bearing the previous observations into consideration, a relation could be made between different parts of process the stimuli ( spinal cord and brain) and the reactions of each of the hands and hence the brains functioning.From the graphs, it becomes evident that tactile responses are fast er than the visual ones. Further much, from the averages, we can conclude that the two hands often varied in their performance of the visual and tactile responses. It has also been ascertained that some of the values do not comply with the general inclining of the other results, thus indicating the existence of other, uncontrolled, factors affecting the results.Conclusion and EvaluationAs our literary sources command, the main function of our nervous system is the coordination of rapid responses to stimuli, including reflexes. A stimulus is a change in the environment which is detected by receptors. Once perceived by the organism, a certain response is evoked and a change in the organism occurs. In this experiment, we investigated the speed of a humans response to tactile and visual stimuli.The findings of this experiment agree to the fact that our tactile responses (performed with closed eyes) are considerably faster from our visual responses (performed with the eyes open). This happens because the signal transmitted from the sensory neurons of our eyes is directly processed by our brain, whereas the signal received from our skin, as the feeling of touch, is processed at the spinal cord and are involved with the local segmental reflexes. As the results of this experiment agree to the general knowledge given from various other literary sources, it can be characterized as reliable.Despite the many efforts to control for the bedevil variables which king affect the very outcome of the experiment, some values have been observed to not comply with the general rule, generated by the rest of them. A number of factors could be responsible for this.In order to make the measurements of height, a ruler has been used, causing the possibility of error to rise. The possible error that might have been involved is that of a 0.05cmAt times, the ruler was not caught at all by the participant and the trial was repeated until a positivist number was achieved. It could be arg ued though that these times are important as well since the inability to react fast could be thought of as a visual or tactile response.External factors might have affected the results of this experiment. Even though it was conducted in a laboratory, noise or distraction could have occurred due to the other classmates.Ways to improve the methodology of the experimentA control of the external confounding variables, such as noise, could help the experiment acquire more focused results.A more precise ruler could have been usedA second tab of the data would be beneficial to the better support of the results found. It would also be good if more participants were used as well.The participants to this work should not be aware of the theoretical points in biology, which would affect their performance due to biases. proximo workSuggested future work, related to this study and its theoretical points, could involve the study of how fast a message is transported through the nervous system or how can this speed be affected by variables such as attention and stress or other neurological conditions. Moreover, individuals could be assessed with visual and tactile stimuli so as to test the different responses between the reaction time of their left and right hands, correlating the results to whether they are left-handed, ambidextrous or right-handed.
