Answer:
Conditioned Stimuli.
Step-by-step explanation:
A conditioned stimulus is any internal or external stimulus that initially causes no reaction in an organism. However, through a classic conditioning process, you can create an answer. An example of this can be seen in the question above, where the word "psychology" was spoken whenever Emily's sister pretended to poke her eyes. At first, the word "psychology" had no effect, but now the word "psychology" makes Emily blink even when her sister doesn't pretend to poke her eyes.
