An occurrence that currently does not produce a response when it is presented. group of answer choices a) neutral stimulus b) conditioned response c) unconditioned response d) unconditioned stimulus.

A) neutral stimulus

Explanation:

A Russian physiologist proposed the mechanism of learning through association.

This process of learning involves the association of two or more stimuli to produce a new type of learning or response and John Watson named this mechanism as Classical conditioning.

The classical conditioning occurs in three stages: Before, during and after conditioning.  In before conditioning, there is a stimulus which does not produce response but with an unconditioned response produces a response called the neutral stimulus.

Thus, a neutral stimulus is the correct answer.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
