introspection to explore mind-structural elements
- Introspection: an examination of one's own mental and emotional process
functionalism)
Psychology:
- Science of behavior and mental process
- Behavior: anything an organism does
- mental process: internal experiences we infer from behavior
- Sigmund Freud studied new emotional responses to childhood experiences & our
unconscious affects our behavior
Behaviorlism:
- Psychology is an objective science
- Studies behavior NO reference to the mental process
Humanistic Psych:
- Against Freud & behavioralism
- Importance of current environmental influence on growth potential- needs for love &
acceptance satisfied

Perspectives:
- Neuroscience: brain & body enable emotions, memories, & sensory experiences
- Evolutionary: natural selection promotes the survival of genes
- Behavioral: how we learn observable responses - behavior is learned
- Psychodynamic: behavior springs from unconscious drives & conflicts (childhood/memories)
- cognitive: how we encode, process, store & retrieve into
- Social/Cultural: how behavior & thinking vary across cultures
Waves of Psychology:
1. Introspection: looking, within/brian
↳ William Wundt - Structuralism
↳ William James - Functionalism
2. Gestalt psychology: The whole
↳ Max Wertheimer - How we experience the world
↳ Total of the experience rather than the parts
3. Psychoanalysis: unconscious
↳ Sigmund Freud
↳ Most feelings come from the unconscious
4. Behavioralism: actions
↳ early/ mid 1900s
↳ cared how you acted, not how you felt
5. :Electric

↳Humans tend to be overconfident
- Barnum effect: the tendency to accept general /vague characteristics of selves & take them to
be accurate
↳ horoscope, MBTI, etc.
- Scientific inquiry fixes confidence
- Curiosity, skepticism, & humility make science possible
Scientific Method:
- Theory linked with observation
- Theory: Organizes, observes & predicts behaviors
- Hypothesis: testable predictions produced by “good” theories
- Operational definition: statements of procedures used to define research variables
↳helps replicate studies with precise predictions that are testable
- Confounding variables: anything that could impact the dependent variable that is not due to the
independent variable
-Random sampling: Everyone has an equal chance of participation
↳Makes results unbiased
-Wording effect: Different wording holds different impacts on people
-Case study: observe technique - one person studied in depth to reveal universal principles
-Naturalistic observation: Watching the subject in the natural environment
Correlation:
↳How one trait is related to another
↳Correlation coefficient: ( ranges from -1 ± 1)
↳Association DOES NOT EQUAL causation
-Illusory correlation: Non-existent trend can have an association - think dangers of bread
-Standard Deviation:
↳A measure of dispersion that shows the spread of scores around the mean
Z-score: measures the distance of a score from the mean
Normal distribution: 68-95-99.7%

Other notable figures include Edward Titchener, who introduced structuralism, and various contemporary psychologists who have shaped modern psychological thought.

What is the significance of the nature vs. nurture debate in psychology?
The nature vs. nurture debate is a central theme in psychology that examines the relative contributions of genetic inheritance (nature) and environmental factors (nurture) to human development and behavior. This debate is crucial for understanding how various traits, behaviors, and mental processes are formed. The guide discusses how this controversy impacts research and theories in psychology, influencing perspectives on intelligence, personality, and psychological disorders. By exploring both sides of the debate, students gain insight into the complexities of human behavior and the interplay between biology and experience.

What ethical guidelines are emphasized in psychological research?
The study guide outlines key ethical guidelines established by the American Psychological Association (APA) for conducting psychological research. These guidelines include obtaining informed consent from participants, ensuring their right to confidentiality, and protecting them from harm. Researchers must also provide debriefing after studies to explain the research purpose and any potential risks involved. Understanding these ethical principles is essential for students as they prepare for careers in psychology, ensuring that they conduct research responsibly and ethically.

How does the scientific method apply to psychological research?
The scientific method is a systematic approach used in psychological research to formulate hypotheses, conduct experiments, and analyze data. The guide emphasizes the importance of developing testable predictions based on theories and operational definitions of variables. By applying the scientific method, psychologists can gather empirical evidence to support or refute their hypotheses. This methodical approach helps minimize biases and enhances the reliability of research findings, making it a cornerstone of psychological inquiry.
