The Double-Edged Sword of Tension: How Moderate Stress Enhances Performance While Over-Focus Impairs It

Abstract

Tension, often considered a negative emotional state, has traditionally been viewed as detrimental to performance, particularly when excessive. However, emerging research suggests that tension, when experienced at moderate levels, may have a facilitating effect on task performance by activating physiological and cognitive resources. This study explores the dual effects of tension on behavioral outcomes, proposing that moderate tension improves performance by enhancing arousal and resource mobilization, while excessive focus on tension can lead to cognitive overload, impairing task performance. Two hypotheses are tested: (H1) moderate tension enhances task performance through physiological arousal mechanisms such as increased adrenaline secretion, and (H2) excessive focus on tension increases cognitive load, leading to poorer performance. A randomized experimental design will be employed, with participants assigned to a moderate tension group, an excessive tension focus group, and a control group. Physiological measures, including heart rate and galvanic skin response (GSR), along with task performance indicators, will be collected. The expected results will provide empirical evidence supporting the positive role of moderate tension in enhancing behavioral outcomes and highlight the detrimental effects of excessive tension focus. This study offers theoretical insights into the dual nature of tension and practical implications for managing tension in high-pressure task environments.
