Self-focus and task difficulty effects on effort-related cardiovascular reactivity.

Area of Science:

• Psychology
• Cardiovascular Physiology
• Performance Psychology

Background:

• Self-focused attention can heighten self-evaluation, influencing performance.
• Motivational intensity theory suggests physiological responses increase with task difficulty.
• Active coping models link self-esteem consequences to performance conditions.

Purpose of the Study:

• To investigate the combined effects of self-focused attention and task difficulty on cardiovascular reactivity.
• To test predictions derived from motivational intensity theory and active coping approaches.

Main Methods:

• Two experiments were conducted involving participants performing tasks under varying levels of self-focused attention and difficulty.
• Performance-related cardiovascular reactivity, specifically systolic blood pressure, was measured.
• Task difficulty was manipulated as unfixed ('do your best'), high, easy, or impossible.

Main Results:

• High self-focused attention significantly increased systolic blood pressure reactivity when task difficulty was high or unfixed.
• This effect was not observed when tasks were either very easy or impossible.
• Findings support the integration of self-evaluation, motivational intensity, and cardiovascular responses.

Conclusions:

• Self-focused attention potentiates cardiovascular reactivity in performance situations with significant outcomes.
• The relationship between self-focus, task difficulty, and physiological response is moderated by perceived achievability.
• These findings have implications for understanding stress responses in achievement contexts.
