Unit 1 of AP Psychology often sets the stage for the entire course. Mastering the foundational concepts early on is crucial for success. This comprehensive guide uses a flashcard approach, but expands on each key term to provide deeper understanding and context, perfect for solidifying your knowledge and boosting your exam score.
What are the major perspectives in psychology?
Psychology isn't a monolithic field; it encompasses diverse perspectives that offer unique lenses through which to examine human behavior and mental processes. Understanding these differing approaches is vital for analyzing psychological phenomena effectively.
-
Biological: This perspective emphasizes the physiological and genetic bases of behavior. It explores how the brain, nervous system, hormones, and genes influence our actions and thoughts. Examples include studying the impact of neurotransmitters on mood or investigating genetic predispositions to certain mental illnesses.
-
Evolutionary: This perspective focuses on how evolutionary pressures have shaped our behavior and mental processes over time. It looks at behaviors as adaptations that enhance survival and reproduction. For example, it might examine mate selection strategies from an evolutionary standpoint.
-
Behavioral: This perspective emphasizes observable behaviors and the environmental factors that shape them. It downplays the role of internal mental states, focusing instead on learning through classical and operant conditioning. Think Pavlov's dogs or Skinner's experiments with reinforcement.
-
Cognitive: This perspective emphasizes mental processes such as memory, language, problem-solving, and decision-making. It explores how we process information and how these processes impact our behavior. Cognitive psychologists might investigate how memory biases affect eyewitness testimony.
-
Humanistic: This perspective emphasizes human potential, personal growth, and self-actualization. It focuses on individual experiences, free will, and the pursuit of meaning. Humanistic psychologists often utilize client-centered therapy techniques.
-
Psychodynamic: This perspective, rooted in Freud's work, emphasizes unconscious motives, conflicts, and early childhood experiences in shaping personality and behavior. It explores the interplay of the id, ego, and superego.
-
Sociocultural: This perspective examines the influence of social and cultural factors on behavior and mental processes. It explores how our interactions with others and the broader societal context shape our thoughts, feelings, and actions. Consider how cultural norms influence conformity or aggression.
What are the different research methods used in psychology?
Understanding different research methods is critical for evaluating the validity and reliability of psychological findings. Each method has strengths and weaknesses.
-
Descriptive Research: This includes naturalistic observation, case studies, and surveys. It describes behavior but doesn't explain it. Naturalistic observation, for example, allows researchers to observe subjects in their natural environment without manipulation.
-
Correlational Research: This examines the relationship between two or more variables. Correlation does not equal causation. A positive correlation indicates that as one variable increases, so does the other, while a negative correlation shows an inverse relationship.
-
Experimental Research: This is the only method that allows researchers to establish cause-and-effect relationships. It involves manipulating an independent variable to observe its effect on a dependent variable, while controlling other factors. A control group is essential for comparison.
What is the difference between a case study and a survey?
-
Case Study: An in-depth investigation of a single individual, group, or event. While providing rich detail, it may not be generalizable to larger populations.
-
Survey: A structured questionnaire used to collect data from a large sample. Surveys are efficient but susceptible to response bias and sampling error.
What are ethical considerations in psychological research?
Ethical research is paramount. Key ethical principles include:
-
Informed Consent: Participants must be fully informed about the study's purpose, procedures, and risks before agreeing to participate.
-
Debriefing: After the study, participants should be informed of its true purpose and any deception used.
-
Confidentiality: Participant data must be kept private and protected.
-
Protection from Harm: Researchers must minimize any physical or psychological harm to participants.
-
Deception: Should only be used when necessary and justified, and participants should be debriefed afterward.
