Question

What level of stress is suitable for optimal performance?

• A. High level of stress
• B. Low level of stress
• C. Moderate level of stress
• D. No stress

Hint:

Think of the inverted-U curve.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Stress affects performance in a curve shaped like an upside-down U. Too little stress leaves us bored. Too much stress overwhelms us. The best results come in between.

Step 2: Recall the idea.
This is the Yerkes-Dodson idea. Performance is highest at a middle level of arousal, which here is a middle level of stress.

Step 3: Check option (1) High stress.
Heavy stress causes anxiety and poor focus. Performance drops. So option 1 is wrong.

Step 4: Check option (2) Low stress.
With low stress there is little motivation to work hard. Performance stays below its best. So option 2 is wrong.

Step 5: Check option (3) Moderate stress.
A moderate level gives enough alertness and drive without overload. This is the best level. So option 3 is right.

Step 6: Check option (4) No stress.
With no stress there is no push to act, so results are poor. So option 4 is wrong.

Final Answer:
Performance peaks at a moderate level of stress, option 3.\[ \boxed{\text{3}} \]
