1. Third Order Conditioning:

    Third order conditioning is a psychological concept that demonstrates the potential for the formation of conditioned responses through a sequence of associative learning processes.

  2. First Order Conditioning:

    In first order conditioning, a neutral stimulus (NS) is repeatedly paired with an unconditioned stimulus (US) to elicit an unconditioned response (UR). Through this classical conditioning process, the neutral stimulus eventually becomes a conditioned stimulus (CS) that can elicit the same response, known as the conditioned response (CR).

  3. Second Order Conditioning:

    In second order conditioning, a previously neutral stimulus (CS1) that has been associated with an unconditioned stimulus (US) through first order conditioning, is then paired with a new neutral stimulus (CS2) several times. Eventually, CS2 alone can elicit a conditioned response (CR) even without the presence of the original US.

  4. Third Order Conditioning:

    In third order conditioning, the process is extended further. A new neutral stimulus (CS3) is introduced and repeatedly paired with CS2, which has acquired its conditioned properties through second order conditioning. As a result, CS3 itself becomes a conditioned stimulus (CS) capable of evoking a conditioned response (CR), even without the presence of CS2 or the original US.

  5. Higher Order Conditioning:

    Third order conditioning is an example of higher order conditioning, which demonstrates that classical conditioning can extend beyond a second order and suggests the potential for multiple levels of associative learning to influence behavioral responses.
