1) Scenаriо Prоmpt: Imаgine yоu аre part of a team designing a new AI system that mimics human cognition. In one of your meetings, someone suggests that the system should follow the same logic as the Information Processing (IP) model, comparing the brain to a computer. As the only cognitive psychologist on the team, you are asked to explain why this model was developed and how it has been applied in understanding human cognition. You also need to explain the model's limitations, particularly in comparison to earlier approaches like introspection and behaviorism. Question: Why was the Information Processing (IP) model developed, and how does the brain-computer analogy help explain cognition? Discuss why this approach was initially considered an improvement over introspective methods and conditioning approaches. Finally, outline some of the key limitations of the IP model, particularly its treatment of emotion and experience. How do these limitations compare to the introspective and conditioning approaches? 2) Scenario Prompt: A research team is studying the brain activity of individuals from the deaf population who rely on lip reading and sign language for communication. They are particularly interested in understanding how the brain processes visual information for language and action, compared to hearing individuals. Their goal is to investigate which brain areas are involved in visual language comprehension, how motor functions are activated during sign language, and how the brain’s visual pathways (dorsal and ventral streams) contribute to these processes. Question: Using your knowledge of brain anatomy and visual processing, explain how the brain of a deaf individual processes visual information differently when lip reading versus using sign language. Discuss the roles of the dorsal and ventral visual streams in these tasks, as well as the brain areas involved in visual language comprehension and motor functions. How do these processes differ from those in hearing individuals? What parts of the brain would be more active in each scenario? 3) Scenario Prompt: You are designing a study that examines how people respond to stressful situations in real time. You are particularly interested in tracking both immediate brain activity during stress and long-term changes in brain regions over time. Question: Discuss the pros and cons of using EEG (ERP) and fMRI for this research. How would each method capture different types of data? Which method would be better for measuring immediate brain activity and which would be better for observing changes over time? Explain how you would combine the two methods, if needed. 4) Scenario Prompt: A famous art museum is planning an exhibit that explores how perception can be deceived through optical illusions. They want to explain to visitors why the brain “sees” things that aren’t there and how Gestalt principles help viewers organize visual stimuli. Question: Explain how the brain’s perception works in this scenario, specifically discussing why optical illusions can trick us. Include an explanation of Gestalt principles (e.g., proximity, closure, continuity) and how the brain automatically uses filters for perception. Why do some illusions occur automatically without conscious thought?
