In the Rescorla-Wagner model, the more surprising the unconditional stimulus is, the greater the need for an organism to it using a conditioned stimulus.

Quasi-experimental approach

Explanation:

The experiment presented above represents a quasi-experimental approach. This type of approach allows the experiment to be established, without the sample used presenting a random distribution, as was done in the experiment presented above. As randomness is ruled out, researchers can assign the formation of treatments and manipulate the composition of experimental groups, but to maintain the credibility of the experiment, it is necessary for the researcher to use an eligibility cut-off mark instead of random assignment.
