Psychological Research Methods

  Short Answer Questions on Psychological Concepts 1. Psychological Research Methods Case Study A case study is an in-depth analysis of a single individual or group, typically involving various data collection methods such as interviews, observations, and psychological testing. For example, a researcher may conduct a case study on a patient with a rare psychological disorder to understand the complexities of the condition and its effects on daily life. Survey Surveys involve collecting data from a large group of people through questionnaires or interviews to gather information about attitudes, behaviors, or characteristics. For instance, a survey could be conducted to assess public opinion on climate change, asking participants to express their views through multiple-choice questions. Naturalistic Observation Naturalistic observation is a research method where researchers observe subjects in their natural environment without interference. An example of this would be studying the social interactions of children in a playground setting to understand how they form friendships and play dynamics. 2. Importance of Sleep Sleep is essential for maintaining physical health, emotional well-being, and cognitive functioning. It plays a critical role in learning and memory by consolidating information learned during the day into long-term memory. During sleep, particularly in the REM stage, the brain processes and organizes memories, making it easier to recall information later. 3. Pavlov's Classical Conditioning Pavlov discovered classical conditioning while studying dogs and their salivation responses to food. He noticed that dogs would salivate not only when food was presented (unconditioned stimulus) but also when they heard a bell (initially a neutral stimulus) that was rung just before feeding. - Neutral Stimulus (NS): Bell (before conditioning) - Unconditioned Stimulus (US): Food - Unconditioned Response (UR): Salivation in response to food - Conditioned Stimulus (CS): Bell (after conditioning) - Conditioned Response (CR): Salivation in response to the bell 4. Generalization and Discrimination In classical conditioning, generalization refers to responding similarly to stimuli that are similar to the conditioned stimulus. For example, if a dog learns to salivate at a bell, it might also salivate at similar sounds. Discrimination, on the other hand, occurs when an organism learns to differentiate between similar stimuli and responds only to the conditioned stimulus. In operant conditioning, generalization means applying learned behaviors in different situations, while discrimination involves responding only to specific cues or signals. 5. Reinforcement Schedules in Operant Conditioning There are four basic reinforcement schedules: 1. Fixed-Ratio Schedule: - Description: Reinforcement is given after a fixed number of responses. - Example: A factory worker receives a bonus for every 10 products made. - Responding: High and steady rate of responding. - Extinction: Easier to extinguish. 2. Variable-Ratio Schedule: - Description: Reinforcement is provided after an unpredictable number of responses. - Example: A gambler wins after an unknown number of bets. - Responding: High and steady rate of responding. - Extinction: Harder to extinguish. 3. Fixed-Interval Schedule: - Description: Reinforcement is given after a fixed amount of time has passed. - Example: A paycheck received every two weeks. - Responding: Moderate rate of responding. - Extinction: Easier to extinguish. 4. Variable-Interval Schedule: - Description: Reinforcement is provided after varying amounts of time. - Example: Receiving random texts from friends. - Responding: Steady rate of responding. - Extinction: Harder to extinguish. 6. Observational Learning and Violence In Bandura's study, children observed adults behaving aggressively toward a Bobo doll. The study demonstrated that children who witnessed this aggressive behavior were more likely to imitate it when they were given the opportunity to play with the doll themselves. This highlights how children can learn violent behaviors through observation, suggesting that exposure to aggressive models can influence their actions and attitudes. 7. Measuring Memory - Recognition: The ability to identify previously learned information when presented with options. Example: A multiple-choice test where students select answers they recognize from study materials. - Recall: The ability to retrieve information without cues. Example: Writing an essay from memory about a topic studied. - Relearning: The process of learning information again after it has been forgotten. Example: A student reviewing material for an exam finds it easier to relearn topics they had previously studied. 8. Flashbulb Memory A flashbulb memory refers to a highly detailed and vivid memory of an emotionally significant event. These memories are often perceived as accurate but can be distorted over time. For instance, many people have flashbulb memories of where they were during significant events like 9/11; however, subsequent discussions and media portrayals can alter these memories. 9. Context and State Dependency Sue is exhibiting context-dependent memory and state-dependent memory behaviors. Context-dependent memory suggests that recall is improved when in the same environment as when the information was learned (e.g., studying in the same room as the test). State-dependent memory indicates that recall is enhanced when in the same physiological or emotional state as when the information was encoded (e.g., drinking coffee while studying and during the test). 10. Personal Reflection on Learning One significant thing I have learned this semester is the complexity of human memory and how easily it can be influenced by external factors. This has changed my understanding of psychology as it emphasizes that human behavior is not just based on experiences but also on how those experiences are processed and remembered. Understanding these concepts has deepened my appreciation for the psychological principles that govern our thoughts and actions.
