The lowest reaction time equates to the person with the fastest reaction time – in this example, student A has the fastest reaction time (255 ms) and student C the slowest (267 ms) Examiner Tip You could be asked to express answers in standard form or as ratios in an exam for this type of question.1. Formulate and test hypotheses regarding reaction times. Introduction: Reaction time is a measure of how quickly an organism can respond to a particular stimulus. Reaction time has been widely studied, as its practical implications may be of great consequence, e.g. a slower than normal reaction time while driving can have grave results.
Keywords: Older adults, Ruler drop test, Simple reaction time, Choice reaction time, Dual-task reaction time, Discrimination reaction time. Introduction. Reaction time (RT) is the time interval between the presentation of a stimulus and the onset of the muscular response to that stimulus . Reaction time is a widely used variable to measure the .
The ruler-drop test has acceptable test-retest reliability that compares favorably with computerized measures of reaction time. 5 – 7 The problem, however, is that using such a test to evaluate recovery from concussion requires serial administration of the test; whether repeating such a test over time (ie, multiple days and weeks) would be .
