Which of the following is NOT considered a strategy for increasing efficacy expectations?

The identification of negative self-talk as a non-strategy for increasing efficacy expectations is accurate because it does not contribute to, but rather undermines, an individual's confidence in their abilities. In contrast, mastery experiences involve successfully accomplishing tasks, which boosts self-efficacy by demonstrating capability. Verbal persuasion, through encouragement and positive affirmations, serves to enhance an individual's belief in their potential, while physiological states refer to the interpretation of bodily responses that can influence motivation and self-efficacy.

In summary, unlike the other strategies that aim to heighten an individual's belief in their capabilities, negative self-talk erodes confidence and has a detrimental effect on efficacy expectations.
