In the Feather Delight task, how long does the feather tickling last?

• A. 15 seconds
• B. 45 seconds
• C. 30 seconds
• D. 60 seconds

Answer: (C)

This item is about how long a standardized sensory stimulus is applied so observations can be compared consistently. In the Feather Delight task, the feather tickling lasts 30 seconds. This duration provides a balance: it’s long enough to elicit a clear reaction across participants but short enough to keep the trial efficient and to avoid excessive fatigue or distress. If the duration were shorter, reactions might not fully develop and measurements could be underestimated; if longer, fatigue or habituation could blur the results and make comparisons less reliable.
