Selfsuggestion

Self-suggestion is a mental technique in which individuals attempt to influence their own thoughts, feelings, and behaviors through repeated self-directed statements, imagery, or routines. It overlaps with autosuggestion and self-affirmation and is used in self-help, education, sports, and some forms of therapy.

The approach gained prominence in the early 20th century through Émile Coué, who promoted regular positive affirmations to improve health and performance. It has since been incorporated into cognitive-behavioral and positive psychology frameworks, often alongside visualization or goal setting.

Practices typically involve crafting simple, believable affirmations, repeating them aloud or silently, and pairing them with mental imagery or cues. Some users write them down or schedule repetition at specific times, such as mornings or before sleep, to establish routine.

Evidence on effectiveness is mixed. Some studies find small to moderate benefits for anxiety, mood, or task performance, especially when combined with action plans. Overall effects are variable and not a substitute for professional treatment in clinical conditions.

Limitations and criticisms include variability in response, the potential for backfire if statements are unrealistic or harshly self-critical, and the importance of credibility and alignment with real behaviors. Self-suggestion is best viewed as a complementary tool within broader strategies for well-being or performance.

Related concepts include autosuggestion, self-talk, cognitive-behavioral therapy, positive psychology, and mental imagery.
