Psychology Overview and Research Methods

Understanding Psychology

  • Definition: Psychology is the scientific study of mental processes like thoughts and feelings, behavior, and brain activity.

Critical Thinking

  • Three Steps to Critical Thinking:
    1. Consider the Source:
    • Assess the credibility of the source:
      • Do they have applicable qualifications?
      • Are they affiliated with a reputable institution?
      • Look for information from scientific journals for credibility.
    1. Evaluate Evidence:
    • Determine if there is strong empirical evidence to support claims rather than relying solely on intuition or belief.
    1. Check Consensus among Sources:
    • Investigate if other reliable sources agree or disagree with the claim to help discern its believability.
  • Outcome:
    • Critical thinking helps distinguish truth from opinion, allowing for informed conclusions.

Institutional Review Boards (IRBs)

  • Purpose of IRBs:
    • To ensure ethical standards in research involving human participants.
  • Ethical Standards:
    1. Privacy: Must respect participant consent for observation.
    2. Confidentiality: Personal information must remain undisclosed.
    3. Informed Consent: Participants must agree to partake after being fully informed.
    4. Protection from Harm: Assess and mitigate potential risks to participants.

Goals of Scientific Research

  • Four Scientific Goals:
    1. Describing: Observing what happens.
    2. Predicting: Anticipating when it occurs.
    3. Controlling: Understanding causes to prevent or alter events.
    4. Explaining: Understanding the reasoning behind occurrences.
  • Scientific Method:
    • Five Steps:
    1. Theory Development: Framework based on existing research.
    2. Hypothesis Generation: Make a testable prediction.
    3. Research Method Testing: Choose an appropriate method for experimentation.
    4. Data Analysis: Utilize statistical methods to evaluate results.
    5. Reporting Findings: Share all results, avoiding cherry-picking data.

Types of Research Methods

  • Descriptive Methods: Used to describe behavior and events.
    • Subtypes:
      A. Case Studies: In-depth examination of individuals or groups.
      B. Observational Studies: Watching behavior in natural settings, with potential biases.
      C. Self-reports: Gathering data through surveys/questionnaires, with advantages and disadvantages.
  • Correlational Methods: Assessing relationships between multiple variables.
  • Experimental Methods: Establishing causality by manipulating variables.

Learning Strategies

  • Six Strategies for Improving Learning:
    1. Improving: Adopt a growth mindset to work hard towards change.
    2. Monitoring: Self-regulate learning by goal-setting and strategy-planning.
    3. Practicing: Use repeated practice to enhance performance.
    4. Attending: Focus on necessary study materials, minimizing distractions.
    5. Connecting: Relate new knowledge to existing knowledge for better retention.

Domains of Psychology

  • Five Domains:
    1. Biological Domain: Connection between brain activity and thoughts/actions.
    2. Cognitive Domain: How mental processes influence behavior.
    3. Developmental Domain: Changes through the life span in terms of mental processes.
    4. Social and Personality Domain: Impact of social factors and characteristics on behavior.
    5. Health Domain: Understanding of mental and physical health factors and behaviors.

Difference Between Theory and Hypothesis

  • Theory: Based on established understanding and prior knowledge.
  • Hypothesis: A testable prediction derived from the existing theory.

Key Theorists in Psychology

  • William Wundt: Established psychology as a distinct discipline in 1879.
  • Edward Titchener: Expanded on Wundt’s thoughts, focusing on structuralism.
  • William James: Introduced functionalism and the importance of consciousness in survival.
  • Sigmund Freud: Developed psychoanalysis, focusing on unconscious processes, with the id, ego, and superego concepts.
  • Ivan Pavlov: Known for classical conditioning; association of stimuli.
  • B.F. Skinner: Pioneered operant conditioning, emphasizing the role of rewards and punishments.

Research Methodology

  • Random Assignment vs Random Sampling:
    • Random Assignment: Each participant has an equal chance of being placed in any condition of an experiment.
    • Random Sampling: Participants are randomly selected from a population to represent that population fairly.
