Final answer:
The concept of E?P expectancy being influenced by an individual's belief in their ability to complete a task is true and is known as self-efficacy. Self-efficacy plays a significant role in motivation and can affect how individuals approach challenges and how persistent they are in the face of adversity. Predicting human behavior involves assessing likely actions based on understanding these motivational factors.
Step-by-step explanation:
The statement E?P expectancy is influenced by the individual's belief that he/she can successfully accomplish the task is true. This concept relates to self-efficacy, which is the level of confidence in an individual's own abilities to complete a task. It is a crucial part of motivation theories, such as those proposed by Albert Bandura, who established that motivation is often derived from the expectations that individuals have about the consequences of their behaviors and their belief in their capability to perform those behaviors. High self-efficacy can lead to setting challenging goals and persisting through difficulties, whereas low self-efficacy can result in avoiding challenging tasks and giving up easily in the face of setbacks.
When predicting human behavior, such as stating what an individual is likely to do, it is not a certainty but a likelihood based on various factors including past behavior, social context, and individual differences such as self-efficacy. In the domain of ambition, needs for achievement are strongly tied to accomplishment and performance, with a high need for achievement driving individuals to take on challenges and persist.
Understanding the conditions under which informational social influence is likely, such as when answers are unclear or the group has expertise, also relates to the broader discussion of self-efficacy and motivation. Essentially, individuals with high self-efficacy are more apt to trust their own judgment and are less influenced by others in situations where they feel competent and self-assured.
