Step 1: Understanding the Question:
The question asks us to analyze the validity of statements concerning stress coping, self-expectancies, and their influence on human behavior as proposed by social-cognitive theories.
Step 2: Detailed Explanation:
• Assertion A states that people who expect to handle stress effectively often do so and report higher life satisfaction. This is a true statement.
• This aligns with Albert Bandura's theory of self-efficacy, which states that an individual's belief in their ability to perform a task directly determines their stress levels, motivation, and coping success.
• Reason R states that the likelihood of a behavior occurring in a specific situation does not depend on an individual's expectancies regarding the outcome of that behavior. This is false.
• According to Julian Rotter's social learning theory, Behavior Potential ($BP$) is a direct function of Expectancy ($E$) and Reinforcement Value ($RV$), expressed as $BP = f(E \& RV)$.
• This means people are highly likely to perform a behavior if they expect that behavior will lead to a positive, successful outcome.
• Therefore, individual expectancies are major determinants of actual behavioral outcomes, rendering Reason R incorrect.
Step 3: Final Answer:
Assertion A is correct because high coping expectancies promote successful coping, but Reason R is incorrect because behavior is heavily dependent on expectancies.
