1. A computer-implemented method, comprising: determining, by a processor, a cognitive load of a plurality of words comprised in a rapid serial visual presentation 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; 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 said controlling step comprises temporarily reducing a presentation rate of the plurality of words responsive to at least one of the increased rate of eye blinks and the increased pupil dilation in relation to the predetermined eye blink range and the predetermined pupil dilation range.
