Question

Which characteristic does not determine the effect of noise on task performance?

• A. Intensity
• B. Luminance
• C. Predictability
• D. Controllability

Answer 1

The Correct Option is B

In the field of psychology, understanding how external factors such as noise impact task performance is crucial. Several characteristics influence this effect: 

• Intensity: Refers to how loud the noise is. High intensity can significantly disrupt task performance by hindering concentration.
• Predictability: Involves whether the noise occurs at expected times. Unpredictable noise tends to be more disruptive because it can catch the individual off guard.
• Controllability: Concerns whether the individual can control or stop the noise. When individuals have control over noise, its negative impact on performance is usually reduced.

However, Luminance, which relates to light intensity and brightness, does not determine the effect of noise on task performance. Therefore, it is the characteristic that does not contribute to how noise affects task performance.

Answer 2

The characteristics that influence the effect of noise on task performance include:

Intensity: The loudness or strength of the noise affects how disruptive it is. The higher the intensity, the more likely it is to negatively impact performance.

Predictability: If the noise occurs at regular intervals or is expected, it is less likely to affect performance. Predictable noise allows individuals to adjust and focus better.

Controllability: The ability to control or stop the noise can significantly reduce its negative impact on performance. If individuals can manage or eliminate the noise, it won't disrupt their tasks as much.

However, luminance refers to the brightness of light, not a characteristic related to noise, and therefore does not influence the effect of noise on task performance.
