Why do I freeze after one wrong answer?

After a mistake, attention often shifts from the next question to the error itself: replaying it, worrying about the score and doubting your ability. That rumination uses working memory and raises anxiety, which can lower performance on subsequent items. A quick reset routine, and remembering that most tests expect some errors, helps limit the spiral.

Worry and rumination compete with the task for limited working memory. Anxiety research links higher test anxiety with lower performance, and a mistake can trigger a short burst of test anxiety even in normally calm people. Perfectionistic expectations make this worse: if you expect to get everything right, one error feels like a verdict rather than normal variation.

On a 40-item reasoning test, most people miss several items. A test taker who treats item 5 as a disaster may lose focus for items 6 to 10. Another who notes "that's one" and moves on keeps her attention on the task.
