<em><u>Neutral stimulus and unconditioned stimulus</u></em><em> are two different parts involved in the </em><em><u>classical conditioning theory </u></em><em>that was developed by </em><em><u>Ivan Pavlov </u></em><em>who was considered as one of the greatest psychologists and behaviorists of his times while conducting his experiment on dogs.</em>
<em><u>A neutral stimulus</u></em><em> is described as a stimulus that doesn't produce any particular response except focusing on attention. Once the neutral stimulus gets connected with an unconditioned stimulus gives rise to a conditioned stimulus. </em>
<em><u>An unconditioned stimulus</u></em><em> is described as a stimulus that is responsible for triggering a particular response automatically, unconditionally, and naturally.</em>
