How is the stimulus concept currently in our lives? (Ivan Pavlov) in TTQA

Answers

Answer:

stimulus is anything that can trigger a physical or behavioral change. The plural of stimulus is stimuli. Stimuli can be external or internal. An example of external stimuli is your body responding to a medicine. An example of internal stimuli is your vital signs changing due to a change in the body.

As humans, we detect and respond to stimulus in order to survive. For example, if you walk outside on a very sunny day, your pupils will constrict to protect your eye from taking in too much light and being damaged. Your body reacts to the stimulus (the light) to protect you.
