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:
- 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.
- Evaluate Evidence:
- Determine if there is strong empirical evidence to support claims rather than relying solely on intuition or belief.
- 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:
- Privacy: Must respect participant consent for observation.
- Confidentiality: Personal information must remain undisclosed.
- Informed Consent: Participants must agree to partake after being fully informed.
- Protection from Harm: Assess and mitigate potential risks to participants.
Goals of Scientific Research
- Four Scientific Goals:
- Describing: Observing what happens.
- Predicting: Anticipating when it occurs.
- Controlling: Understanding causes to prevent or alter events.
- Explaining: Understanding the reasoning behind occurrences.
- Scientific Method:
- Theory Development: Framework based on existing research.
- Hypothesis Generation: Make a testable prediction.
- Research Method Testing: Choose an appropriate method for experimentation.
- Data Analysis: Utilize statistical methods to evaluate results.
- 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:
- Improving: Adopt a growth mindset to work hard towards change.
- Monitoring: Self-regulate learning by goal-setting and strategy-planning.
- Practicing: Use repeated practice to enhance performance.
- Attending: Focus on necessary study materials, minimizing distractions.
- Connecting: Relate new knowledge to existing knowledge for better retention.
Domains of Psychology
- Five Domains:
- Biological Domain: Connection between brain activity and thoughts/actions.
- Cognitive Domain: How mental processes influence behavior.
- Developmental Domain: Changes through the life span in terms of mental processes.
- Social and Personality Domain: Impact of social factors and characteristics on behavior.
- 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.
