An archer experiences a performance decline during an important competition, exhibiting increased heart rate and muscle tension. Which psychological effect dominates in this scenario?

💡 Explanation

Excessive arousal impairs motor control because it leads to muscle tension and a narrowed attentional focus, disrupting fine motor skills; therefore performance declines, rather than arousal optimizing it, as the Yerkes-Dodson law suggests performance decreases beyond optimal arousal.
