1. A computer-implemented method, comprising: receiving, by a processor, a plurality of words comprised in a rapid serial visual presentation; determining, by a processor, a cognitive load of the plurality of words by using at least one metric, the cognitive load being determined on any of a word level and a word sequence level; calculating, by the processor, a variable presentation rate for the plurality of words based on the cognitive load, the variable presentation rate capable of being varied on any of the word level and the word sequence level; and controlling, by the processor, a displaying of the plurality of words on a display device in accordance with the calculated variable presentation rate based on a threshold by temporarily reducing the variable presentation rate responsive to the cognitive load being above the threshold.

The computer-implemented method of claim 1 , wherein the at least one metric comprises an eye-based metric for identifying at least one of an increased rate of eye blinks and an increased pupil dilation in relation to a predetermined eye blink range and a predetermined pupil dilation range.
