Main evidence and numbers
| Condition | Published mean | Wetin dem measure |
|---|---|---|
| Sound signal | 228.01 ms | Each student fastest one out of five tries |
| Light signal | 247.60 ms | Each student fastest one out of five tries |
| Difference | 19.59 ms | Subtraction of the two group averages |
These values come from Table 1 of the comparison study; dem no be general rule about hearing and seeing. Choosing the fastest try make the result different from the average or middle value of all responses. The people wey take part na first-year medical students, 60 men and 60 women; this kind recruitment no set standard for children, older adults or gamers. Jain et al., 2015
Wetin dey happen between the signal and the response?
Simple reaction task ask you to make one known response when signal show. E involve noticing the signal, getting ready and starting movement, and recording that movement. Choice task add identifying the thing wey show and choosing response. This difference matter pass whether website call the result reflex: pressing button by choice no be measure of nerve signal by itself. Woods et al., 2015 Woods et al., 2015
The well-known link between number of response choices and reaction time show why sound-detection task and visual game no need give the same result. Game fit ask you to choose between actions, while the sound test ask for only one response. Comparing them no fit show sensory advantage by itself. Hick, 1952
Age and sex dey change the comparison?
The student study report say the average for male groups faster, but e no fit tell us how much of the difference come from who dem select, experience or other things about them. The small groups wey exercise especially no fit support cause-and-effect conclusion about exercise. The bigger Woods studies show age patterns for their visual tasks; dem no give any adjustment for sound-versus-light wey fit apply to everybody. Jain et al., 2015 Woods et al., 2015 Woods et al., 2015
Wetin dey affect am?
Equipment fit make one sense look faster
Sound score depend on when sound really reach the ear. Visual score depend on when screen really change. The time wey browser schedule, when the thing show physically, and when dem record button press na different events. Tests of different platforms show say timing accuracy and variation depend on browser, operating system, experiment system and hardware. So computer visual result and phone headphone result dey compare two measuring systems as well as two senses. Anwyl-Irvine et al., 2020 Bridges et al., 2020
This one explain too why the fact say light travel faster than sound no settle the matter. For computer task wey dey near, the experiment need control how brain process the signal and equipment delay. The comparison paper measure responses to particular lights and sounds, no be responses to lightning and thunder wey far away. Jain et al., 2015
Wetin you fit realistically do?
If na informal comparison, use the same device, response button, instructions and number of tries, and compare the same kind summary. Even so, if nobody calibrate the setup, you no fit subtract the two scores and call the difference your own sensory-processing speed. Anwyl-Irvine et al., 2020 Bridges et al., 2020
Consistency when you repeat the task matter too. One strong average effect for experiments fit happen together with poor reliability when dem dey rank individuals. Lack of sleep fit change attention and how steady your responses be, so one session no be strong evidence say one sense slow pass normal. These na reasons to understand the task carefully, no be reasons to chase one particular millisecond target. Hedge et al., 2017 Lim et al., 2010

Test for how quick you dey react
Try the visual reaction time test to see how you respond to visual signal wey you no expect. Use the same input method every time. E no include calibrated sound comparison, so use the published comparison as background information, no be as conversion formula.
Common questions
How much hearing dey faster pass seeing?
No fixed difference dey for one person. The student study find 19.59 ms difference between group averages using the fastest out of five method. Other signals and ways of scoring fit give different differences. Jain et al., 2015
Headphones good for comparing the two?
Audio equipment add its own way of presenting the sound. To compare fairly, you need to measure or control that way; no just assume say its delay equal the screen delay. Anwyl-Irvine et al., 2020
If visual score slow, e mean say person get eye problem?
This task combine attention, noticing, movement and equipment delay. E no identify wetin cause slow response. Woods et al., 2015
