According to the social learning theory, what factor can discourage learners from trying new behaviors?

The correct choice emphasizes the impact of negative past outcomes on a learner's willingness to try new behaviors. In social learning theory, experiences play a crucial role in shaping an individual's approach to learning and behavior. If a learner has previously encountered negative consequences when attempting similar behaviors, it can lead to fear of failure or reluctance to engage in those behaviors again. This past experience acts as a strong internal deterrent, prompting the learner to avoid behaviors they associate with unfavorable results.

In contrast, other factors such as lack of observational opportunities, absence of skilled instructors, or limited access to resources do not have the same immediate psychological impact as negative past experiences. While these factors can affect learning environments and the transfer of new skills, they do not inherently create the same level of anxiety or reluctance that negative experiences induce. This makes the influence of previous negative outcomes particularly significant in the context of social learning and behavior modification.
