this is all the info in the lab

Answer 1

1. The subjects' mean reaction time to visual cues took minutely longer than the subjects' mean reaction time to auditory cues.
2.Stimuli from the auditory receptors travels to the brain faster than stimuli from the photoreceptors, even though light travels significantly faster than sound. The pathway that visual stimuli take to get to the brain is more neurologically complex than the pathway that auditory stimuli take. The more complex a pathway, the longer it takes for a stimulus to reach the brain. Therefore, reaction to visual stimuli is slightly slower than reaction to auditory stimuli.

4. Overall, both of the subjects had a significantly faster reaction time to auditory prompted cue over any other auditory or visual cues. With the help of a one-word cue immediately before signal, the subjects were able to react more efficiently. A faster reaction time results due to the prior knowledge of a cue compared to a situation when the cue is random and unprompted. Also, slower reactions are expected when responding to predicted cues because the subject may be counting either too slowly or too fast compared to the cue that is set on exact time interval.

Exercise 4 :-
1. When analyzing the subjects' reaction times to prompted and predicted auditory cues, the two subjects responded most quickly to the prompted cues. Between the two subjects, there was an average increase of 0.1 second in response to a prompted cue, which is relatively 50% faster than the predicted auditory cue.
2.Both subjects responded most slowly to the auditory predicted cues. Faster reaction times to auditory random without cues might have resulted because the subjects were focused since they knew they would not be prompted. The prompted auditory cue warned subjects about the imminent proceeding cue. In contrary, the auditory predicted cue required that the subjects multitask counting the predicted times and signaling the cues. Perhaps if subjects had access to digital time keepers which would eliminate the need to mentally keep track of time, their reactions times to auditory predicted cues would be more similar to auditory prompted cues.
3. Both of our subjects responded faster to auditory stimuli than to visual stimuli. This was consistent with our hypothesis since the visual neural pathway is more complex than the auditory neural pathway. Therefore, our results are expected to be consistent with the observations made by other groups.
