Abstract
An apparatus and method for predicting cognitive performance of an individual based on factors including sleep history and the time of day. The method facilitates the creation of predicted cognitive performance curves that allow an individual to set his/her sleep times to produce higher levels of cognitive performance. The method also facilitates the reconstruction of past cognitive performance levels based on sleep history.
Claims51
A method for determining a predicted cognitive performance level comprising:
- a. inputting a data series having wake states and sleep states of an individual,
- b. selecting a function based on the wake states and sleep states in the data series,
- c. calculating a cognitive performance capacity based on the selected function,
- d. modulating the cognitive performance capacity with a time of day value,
- e. outputting the modulated value as the predicted cognitive performance, and
- when a piece of data within the data series is inconclusive, then
- selecting at least two functions,
- determining a cognitive performance capacity using each function,
- modulating each cognitive performance capacity with a time of day value,
- providing each modulated value, and
- repeating the steps a through e for each modulated value at least once.

A method for determining a predicted cognitive performance comprising:
