Which of the following is not considered as self- generated feedback?

Assurance is not treated as self-generated feedback, because it is reassurance received from outside rather than information a learner produces from their own work.

Previewing is self-generated feedback, as the learner looks ahead over the task to check direction.

Retracing is self-generated feedback, as the learner goes back over steps to detect errors.

Observation is self-generated feedback, as the learner monitors their own ongoing performance.

Self-generated feedback is internal, arising from the learner's self-monitoring rather than an external source.

It contrasts with external feedback given by a teacher, peer or evaluation system.
