Negative feedback (-) feedback control systems are inhibitory, they oppose or "negate" a change by creating a response that is opposite in direction to the initial disturbance.
Positive feedback (+) feedback control systems are stimulatory, positive feedback tends to amplify or reinforce the change that is occurring.
Stimulus and Response -Stimulus: A change in a variable that elicits a reaction in a feedback loop - Response: The reaction to the stimulus, the operation of the effector in a feedback loop.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
