Visual Stimulus And Response Lab Report

a. In this lab we studied the time taken between a stimulus and the response of six different participants, particularly using a visual stimulus and then a response by pressing the event marker. The baseline data was recorded with the participant listening to no music and then another set of data with that same participant listening to slow music playing in their ears.
b. According to the lab manual, a visual signal is detected by bipolar cells synapsing directly with ganglion cells-receptor cells that are responsible for the pupillary reflex and send graded potentials to these bipolar cells. This direct synapse is then sent to the visual cortex which is located in the occipital lobe. To understand what a graded potential is, Dr. Tandy defines
c. The purpose of this experiment was to determine if there was any difference in visual stimulus reaction time when the participant listened to slow music than listening to no music.
a. I composed that listening to slow music while going through the visual stimulus and reaction experiment would cause the participant to be slower at responding to the visual signal. My reasoning behind this hypothesis is from personal experience in that listening to slow music makes my body movements more relaxed and at ease. In a paper written by, Krysten R. Chadwick from Ohio State University, her results show that people tend to drift from their original finger tap and tap their fingers to the beat of the music they are hearing. Her results also indicated that the rate of the auditory stimulus influenced the
To start this experiment, the Lab Scribe software needs to be set-up. For our groups particular experiment, the event marker is the only piece of equipment needed that is a part of the software. Other materials that will be needed are a pair of headphones and soft music. Once the data recording software is all set, position the participant so that they can only see the computer screen and not the keyboard. Have one group member press the F1 key after another member presses the record button. Press the F1 key about 10-15 times. Stop the recording by pressing stop where the group member first pressed start to record. Record the data using the T2-T1 formula data recording tool within the software program. Copy this data into a separate excel document. This data is the baseline data. Using the same participant, have them put in the headphones. Play the soft music, then repeat the experiment of one group member pressing the record button, and the other member pressing the F1 key. Transfer this soft music results next to the baseline results and keep each participants data separate from the other participants. In other words, there should be one baseline and one slow music data results for the six total participants. Repeat this five more times to total to the six participants. Entirety of procedure is completely harmless and
