11. A method for facilitating user-task/plan-based content presentation to affect user remembrance of content, the method comprising: receiving, via one or more processors, content to be presented to a user, the content comprising a first content portion; obtaining, via one or more processors, a first importance indicator indicating an importance of the first content portion with respect to a task or plan of the user; obtaining, via one or more processors, based on user data related to the user, presentation style boundary conditions, the presentation style boundary conditions indicating a presentation style set from which one or more presentation styles are to be selected for presenting the content to the user, the presentation style set comprising (i) a first presentation style associated with a first difficulty level and (ii) a second presentation style associated with a second difficulty level, the second difficulty level being indicative of requiring less effort from the user to read the content than the first difficulty level; selecting, via one or more processors, based on the first importance indicator, from the presentation style set, the first presentation style to be used over at least the second presentation style for presenting the first content portion to the user; causing, via a display, presentation of the content based on the selected first presentation style such that the first presentation style is used to present the first content portion on the display; detecting, via one or more sensors, during the presentation of the first content portion, sympathetic autonomic activity data indicating the user's sympathetic autonomic activity related to the task or plan of the user; determining, during the presentation of the first content portion, based on the sympathetic autonomic activity data, whether the user's sympathetic autonomic activity corresponds to a baseline sympathetic autonomic activity level; and adjusting, via the display, the presentation of the first content portion based on a determination that the user's sympathetic autonomic activity corresponds to the baseline sympathetic autonomic activity level such that a presentation style that is easier to read than the first presentation style is used to present the first content portion on the display.
11. A method for facilitating user-task/plan-based content presentation to affect user remembrance of content, the method comprising: receiving, via one or more processors, content to be presented to a user, the content comprising a first content portion; obtaining, via one or more processors, a first importance indicator indicating an importance of the first content portion with respect to a task or plan of the user; obtaining, via one or more processors, based on user data related to the user, presentation style boundary conditions, the presentation style boundary conditions indicating a presentation style set from which one or more presentation styles are to be selected for presenting the content to the user, the presentation style set comprising (i) a first presentation style associated with a first difficulty level and (ii) a second presentation style associated with a second difficulty level, the second difficulty level being indicative of requiring less effort from the user to read the content than the first difficulty level; selecting, via one or more processors, based on the first importance indicator, from the presentation style set, the first presentation style to be used over at least the second presentation style for presenting the first content portion to the user; causing, via a display, presentation of the content based on the selected first presentation style such that the first presentation style is used to present the first content portion on the display; detecting, via one or more sensors, during the presentation of the first content portion, sympathetic autonomic activity data indicating the user's sympathetic autonomic activity related to the task or plan of the user; determining, during the presentation of the first content portion, based on the sympathetic autonomic activity data, whether the user's sympathetic autonomic activity corresponds to a baseline sympathetic autonomic activity level; and adjusting, via the display, the presentation of the first content portion based on a determination that the user's sympathetic autonomic activity corresponds to the baseline sympathetic autonomic activity level such that a presentation style that is easier to read than the first presentation style is used to present the first content portion on the display. 12. The method of claim 11 , wherein the content comprises the first content portion and a second content portion, the method further comprising: obtaining, via one or more processors, a second importance indicator indicating an importance of the second content portion with respect to the task or plan of the user; and selecting, via one or more processors, based on the second importance indicator, from the presentation style set, the second presentation style to be used over at least the first presentation style for presenting the second content portion to the user, wherein causing the presentation of the content comprises causing, via the display, the presentation of the content based on the selected first presentation style and the selected second presentation style such that (i) the first presentation style is used to present the first content portion on the display and (ii) the second presentation style is used to present the second content portion on the display.
