Key Concepts in Psychology

Experimental Method
  • Understanding of experimental design is crucial for psychological research.
  • Types of Studies:
    • Lab Experiment: Controlled environment, manipulation of variables.
    • Field Experiment: Conducted in a real-world setting.
    • Natural Experiment: Observes naturally occurring variables without manipulation.
Conditioning
  • Unconditioned Stimulus (UCS): A stimulus that naturally and automatically triggers a response.
  • Conditioned Stimulus (CS): A previously neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response.
  • Unconditioned Response (UCR): The natural response to an unconditioned stimulus.
  • Conditioned Response (CR): The learned response to a previously neutral stimulus.
Research Techniques
  • Sampling Techniques: Understanding different ways to select participants:
    • Random Sampling: Every individual has an equal chance of being selected.
    • Opportunity Sampling: Selecting individuals who are readily available.
    • Self-Selected Sampling: Participants volunteer themselves for the study.
    • Purposive Sampling: Participants are chosen based on specific characteristics.
    • Snowball Sampling: Existing study subjects recruit future subjects from among their acquaintances.
Key Studies
  • Little Albert Study: Explores classical conditioning by conditioning a fear response.
  • Rosenthal & Jacobson Study (Pygmalion Effect): Explores the impact of teacher expectations on student performance.
  • Anderson & Pichert Study: Investigates schema theory in memory recall.
  • Bransford & Johnson Study: Examines how context affects memory retention.
  • Pillavin & Rodin Study: Studies altruism and bystander behavior.

Models of Memory

Types of Memory
  • Sensory Memory: Brief retention of sensory information.
  • Short-Term Memory: Holds a small amount of information for a limited duration.
  • Long-Term Memory: Ongoing storage of information, potentially for a lifetime.
Models of Memory
  • Multi-Store Model: Includes sensory memory, short-term memory, and long-term memory.
  • Working Memory Model: Introduces components like the Central Executive, Phonological Loop, Visuospatial Sketchpad, and Episodic Buffer.

Memory Research

Biases in Memory Research
  • Maturation Bias: Changes in participants over time impacting study results.
  • Demand Characteristics: Cues in a study that suggest how participants should behave.
  • Experimenter Bias: Researchers' expectations affect the outcome of the study.
Memory Theories and Concepts
  • Cognitive Load Theory: states that memory performance can be affected by the amount of information processed.
  • Cognitive Dissonance: Tension arises from holding conflicting cognitions.
  • Schema Theory: Frameworks that organize and interpret information.

Ethical Principles in Psychology Research

  • Informed Consent: Participants must be aware of their involvement and agree to it.
  • Debriefing: Participants should be informed of the study's true nature afterward.
  • Right to Withdraw: Participants can leave the study at any time.
Ethical Studies
  • Milgram Study: Examines obedience to authority, demonstrating ethical concerns regarding deception and psychological harm.
  • Sherif Study: Investigates group behavior and conformity under controlled conditions.

Cognitive Biases

  • Confirmation Bias: Tendency to search for, interpret, favor, and recall information confirming one's preconceptions.
  • Framing Effect: Decisions are influenced by how information is presented.
  • Anchoring Bias: Relying too heavily on the first piece of information encountered.

Cognitive Models

  • Dual Process Model: Differentiates between two modes of thinking:
    • System 1 Thinking: Fast, automatic, and emotional.
    • System 2 Thinking: Slower, deliberate, and more logical.

Qualitative Methods

  • Different qualitative research methods including interviews, focus groups, and case studies to gather in-depth insights.

Generalizability and Validity

  • Internal Validity: The degree to which a study design accurately establishes a cause-and-effect relationship.
  • External Validity: The extent to which study findings can be generalized to real-world settings.
Trending Topics
  • Exploring application issues such as ethical concerns, the impact of cognitive biases, and frameworks in research designs for real-world relevance.

Free Response Questions (FRQ) Preparation

  • Get familiar with responding to questions in 4 to 5 sentences.
  • Focus on referencing measurement studies, explaining causality, and discussing behavioral changes over time.
  • Be ready to articulate how and why effects occur in individuals or in behavior changes based on the context of studies covered in this exam prep.
