A term used to describe a reaction that is triggered by a secondary (or less direct) stimulus rather than the main or primary stimulus.

एक प्रतिक्रिया जो मुख्य या प्राथमिक उत्तेजना के बजाय द्वितीयक (या कम सीधे) उत्तेजना द्वारा शुरू की जाती है।

English Usage: The secondary stimulus response in the experiment was not as strong as the primary one.

Hindi Usage: प्रयोग में द्वितीयक उत्तेजना प्रतिक्रिया प्राथमिक प्रतिक्रिया जितनी मजबूत नहीं थी।
