Abstract: The computer generates geometrical figures based on predefined parameter values. The parameter values are ranked according to difficulty level so that the computer may generate tasks that visually look differently but are based on the same set of parameter values.

Abstract: The method is for training a working memory of a user. A maximum ability of a user is established. A first sequence of stimuli of a first trial is displayed to the user. The user is requested to remember the first sequence of stimuli. A delay of a predetermined time is established during which the first sequence of stimuli is not visible to the user. The user is enabled to enter an answer sequence after an expiration of the delay in response to the request to remember the first sequence of stimuli displayed prior to the delay. A first difficulty level of the first stimulus presentation sequence is determined. The first difficulty level is compared to the maximum ability of the user to develop a difficulty ratio. The difficulty ratio is presented to the user.

Abstract: The present invention relates to a computer training system for training working memory capacity of a user of a computer within the system, and a computer program to be used within said system, a first task of a first difficulty level is presented to the user, a delay of a predetermined time is performed, during which delay the task is not visible or audible to the user, and during which delay it is not possible to enter an answer into the computer, the difficulty level of a subsequent task to be presented to the user is changed in accordance with predetermined adaptation rules and based on said evaluation such that the difficulty level of the subsequent task is adapted to the capacity of the user, subsequent tasks are presented to the user adapted to the capacity of the user in until a predetermined time limit is exceeded or until a predetermined number of tasks has been performed.
