* '''<span id="Forgetting index">Forgetting index</span>''' determines the default requested [[Glossary#forgetting index | forgetting index]]. This forgetting index will be used by all newly created [[categories]]. As a result, all new items added to those categories will use this forgetting index by default. Forgetting index determines the speed of learning. When you first run SuperMemo, it is set at 10%. This means that SuperMemo will tune the learning process in such a way that you will stand 10% chance of forgetting any given item at repetitions. You can reduce the forgetting index to 3% at the cost of a significant slow-down of the learning process. You can also increase it up to 20% to greatly increase the [[Glossary#acquisition rate | speed of learning]] at the cost of [[Glossary#retention | knowledge retention]]. Increasing the forgetting index further makes little sense as both retention and the speed of learning will decrease (you can read about it in [http://supermemo.com/articles/theory.htm Theoretical aspects of SuperMemo] or see it for yourself by using '''[[Tools menu | Tools]] : Statistics : Simulation'''). All individual items can have their individual forgetting index set with '''Edit : [[Element parameters dialog box | Edit parameters]]''' on the [[element menu]] (''Ctrl+Shift+P''). Before you change that value, however, the default forgetting index will be determined by the default value of the parent category, which in turn is taken from the setting at '''[[Tools menu | Tools]] : [[Options]] : Learning : Forgetting index'''.

* '''<span id="Midnight clock shift">Midnight clock shift (hours) </span>''' - the number of hours after midnight on which the new repetition day begins. For your convenience you should put the midnight-clock-shift value to the middle of your average night. For example, if your average sleeping hours are 23:00 - 7:00 (i.e. 11 p.m. - 7 a.m.), the middle of your night comes at 3 a.m. (you set the slider at 3).

Midnight clock shift is extended to 16 hours for people in shift work and those who work in unusual hours (e.g. as a result of [http://supermemo.com/articles/sleep.htm DSPS or ASPS sleep disorders]). The change of date will not occur until you restart SuperMemo. For that reason, you should always close SuperMemo for the night

* '''Sound feedback''' - decide the way in which SuperMemo will react to passing and failing grades:
*'''Algorithm SM-18 Alerts''' - alert on interval discrepancies large enough (in percent) for [[Glossary:Interval|intervals]] long enough (in days) as compared with Algorithm SM-15:
** '''None''' - provide no sound feedback
**'''Difference [%]''' - raise alert when interval difference (in percent) as compared with Algorithm SM-15 is equal or larger than the specified amount
** '''Default''' - use default Windows sounds to indicate bad and good grades
**'''Interval [days]''' - do not raise an alert for intervals shorter than the specified amount
** '''Custom''' - define your own sounds with '''[[Options]] : Learning : Custom sounds''' (see below)
**'''Factor''' - raise alert when interval quotient as compared with Algorithm SM-15 is larger than the specified amount
* '''Custom sounds''' - if the '''Custom''' option in '''[[Options]] : Learning : Sound feedback''' is checked, '''Custom sounds''' makes it possible to pick sound [[Glossary#registry member | registry members]] for grade sound feedback. For example, if you have a low beep in the sound registry member named ''Fail'', and a cheerful Tada signal named ''Tada'', you can type in those two names at '''Custom sounds: Success'''=''Tada'', '''Failure'''=''Fail''. You can test the sounds by pressing play buttons on the right. To import sounds to sound registry use '''[[Search menu | Search]] : Sounds''' and choose '''Tools : Import files''' on the [[registry menu]]

This is the interpretation of individual fields:

  • Forgetting index determines the default requested forgetting index. Forgetting index determines the speed of learning. When you first run SuperMemo, it is set to 10%. This means that SuperMemo will tune the learning process in such a way that you will stand a 10% chance of forgetting any given item at repetition. You can reduce the forgetting index to 3% at the cost of a significant slow-down of the learning process. You can also increase it up to 20% to greatly increase the speed of learning at the cost of knowledge retention. Increasing the forgetting index further makes little sense as both retention and the speed of learning will decrease (you can read about it in Theoretical aspects of SuperMemo or see it for yourself by using Toolkit : Statistics : Simulation). All individual items can have their individual forgetting index set with Edit : Edit parameters on the element menu (Ctrl+Shift+P). Read more: Forgetting index
  • Always randomize final drill - scramble the sequence of repetitions in the final drill before moving to the final drill stage
  • Skip final drill - do not create the final drill queue. Final drill must always be considered of lower priority than reviewing the outstanding material. For that reason, in a heavily overloaded incremental reading process you may come to a point where your learning sessions always end with Postpone (or start with Auto-postpone). If this is the case, building the final drill queue makes little sense
  • Midnight shift - the number of hours after midnight on which the new repetition day begins. For your convenience you should put the midnight-clock-shift value to the middle of your average night. For example, if your average sleeping hours are 23:00 - 7:00 (i.e. 11 p.m. - 7 a.m.), the middle of your night comes at 3 a.m. If you then set your midnight shift at 3 a.m. (slider at 3), you are least likely to be in a situation when you need to change the midnight clock shift to correctly execute repetitions belonging to a given waking day. If on occasion you come back home late at 2:30 a.m. and are still able to make repetitions, SuperMemo will behave like there was no date change at midnight. On the other hand, if you wake up at 3:30 a.m. and decide to make repetitions at that time, SuperMemo will already consider those repetitions as belonging to the new day. Midnight clock shift is extended to 16 hours for people in shift work and those who work in unusual hours (e.g. as a result of DSPS or ASPS sleep disorders). The change of date will not occur until you restart SuperMemo. For that reason, you should always close SuperMemo for the night
  • Algorithm SM-18 Alerts - alert on interval discrepancies large enough (in percent) for intervals long enough (in days) as compared with Algorithm SM-15:
    • Difference [%] - raise alert when interval difference (in percent) as compared with Algorithm SM-15 is equal or larger than the specified amount
    • Interval [days] - do not raise an alert for intervals shorter than the specified amount
    • Factor - raise alert when interval quotient as compared with Algorithm SM-15 is larger than the specified amount
