Finger Response Times to Visual, Auditory and Tactile Modality Stimuli
By Christopher Watts 9MLO

Introduction:
The time it takes from when an individual responds to a certain stimulus that they have detected is commonly referred to as reaction time. This delay in time is caused by the amount of time it takes information to go through the nervous system and then towards your brain. Your brain acts as the processor of your body and translates these informative signals so that your body can act accordingly. Reaction time is important so that humans can act fast and accordingly to whatever situations they come across. Athletes such as short distance runners and cricketers require fast reaction times in order to enhance their ability and ultimately enhance their overall performance. The
To enhance road safety for pedestrians, a crosswalk warning system with flashing lights adjacent to a marked crossing is used. In addition to the use of vision, auditory modality is widely used in transport, health care, and industrial environments as it has an immediate arousing effect. There was an investigation of the level of urgency of non-verbal auditory alarms used in aircraft environments, and found that the ‘siren-like quality sounds’ were judged as the most urgent. The siren type of auditory alarm was also rated more alerting than the buzzer one. A tactile reaction time is the reaction from the sense of touch. This is slightly different to the pain reaction time as touch and pain receptors aren 't exactly the same. Tactile reaction time is used when the stimuli physically touches you such as if somebody were to touch you on the back. There is a common misunderstanding with 'reflexes ' and 'reaction time ' but they are actually quite different. Reflexes are developed survival tactics that are involuntary actions. These can still be improved but will
