In Freud's study involving Little Hans, opportunity sampling was utilized, which is evident from the way the participant was selected for the study. Freud's choice of Little Hans was based on his existing relationship with the boy's father, who had sought Freud's help regarding his son's phobia of horses. This approach exemplifies opportunity sampling because Freud capitalized on a specific situation where he had direct access to the subject of interest, rather than implementing random, stratified, or systematic methods to gather a broader sample.

Opportunity sampling often involves selecting individuals who are readily available and willing to participate. In this case, the selection of Little Hans was convenient for Freud and allowed for an in-depth analysis of the boy's phobia and associated psychoanalytic theories, demonstrating how opportunity sampling can effectively facilitate qualitative research in psychology.
