Carolina wants to investigate how mental processes, such as attention, affect the amount of time that a child will work on a difficult task. Carolina's research is most similar to the research approach taken by who helped develop a. Rogers; humanistic psychology b. Watson; behaviorism c. Miller; cognitive psychology d. Wertheimer; Gestalt theory

Carolina's research focuses on mental processes and their influence on a child's behavior (i.e., working on a difficult task). Review the approaches and theories of the listed psychologists: a. Rogers: Humanistic psychology focuses on human potential, self-actualization, and personal growth. b. Watson: Behaviorism studies observable behavior and its relationship to environmental stimuli. c. Miller: Cognitive psychology focuses on mental processes, such as perception, memory, thinking, and problem-solving. d. Wertheimer: Gestalt theory studies the holistic nature of the human mind, emphasizing the importance of the organization and structure in cognitive processes. #Step 2: Compare Carolina's Research to Each Approach#

Compare the focus of Carolina's research (mental processes such as attention and their effect on the duration of working on task) with each psychological approach: a. Rogers: While humanistic psychology emphasizes personal growth, it does not specifically focus on mental processes or their effect on behavior; this would not be the approach Carolina's research aligns with. b. Watson: Behaviorism focuses on observable behavior, not mental processes; hence, this is not the best choice for Carolina's research. c. Miller: Cognitive psychology directly focuses on mental processes and their relationship with behavior. This is most in line with Carolina's research. d. Wertheimer: Gestalt theory takes a holistic approach to cognitive processes, but it does not directly focus on the influence of mental processes like attention on specific behaviors. #Step 3: Identify the Most Appropriate Research Approach#

Based on the comparison of each psychologist's research approach with Carolina's research topic (mental processes and their effects on behavior), the most appropriate research approach is: c. Miller; cognitive psychology
