The present disclosure relates to methods and tools for enhancing cognition and improving well being in an individual. The methods involve presenting to an individual a task to be performed, presenting to the individual an interference, and receiving inputs from the individual. Where the interference is a distraction, the individual is to ignore the interference. Where the interference is an interrupter, the individual is instructed to respond to the interrupter as a secondary task and is considered to be multi-tasking. Inputs are then also received from the individual pertaining to this secondary task. The methods encompass iterations of these presenting steps and receiving of the input, and generation of analysis and/or feedback to the individual. The analysis can include a comparison of the performances with or without each type of interference.
