Psychology in Your Life — Chapter 1 Notes

What is psychology?

• Psychology has two meanings:
  • Subjective/personal scope: topics like the psychology of relationships or the psychology of learning (how I feel about how I learn).
  • Objective/scientific scope: the impersonal study that seeks to understand who we are, why we do what we do, and why we think what we think.
• A simplified clinical/research example:
  • In marriage and family counseling, infidelity raises questions about thoughts and behaviors to understand underlying processes; in research settings, we learn more about these processes to inform practice.
• Why ask why we think before we act in order to better understand decisions (e.g., why I chose to wear pants this morning).
• Bottom line: psychology aims to explain thoughts, feelings, and behaviors and how they interact across individual and social contexts.

Why is psychology important?

• Perspectives from students:
  • One view: psychology contributes to mental health and well-being.
  • Another view (metaphor): life is a stem of choices added together; if we act emotionally all the time, our choices may not be optimal.
  • A third view: psychology frames almost everything we do; the brain drives most of our functioning.
• The brain as the engine for experience and behavior:
  • The brain governs mental activity, perception, senses, and the processing of hunger, tiredness, mood, etc.
  • Sensing and perception influence behavior (e.g., hunger and sleepiness can lead to social withdrawal or lateness).
  • Psychology helps explain individual behavior and how we form friendships, romantic relationships, and social interactions.
• The mind as the system that makes sense of the world and the brain as the biological substrate for mental activity and behavior.
• The science of psychology emphasizes empirical evidence and measurable methods; in classroom practice, we emphasize empiricism over intuition or popular media claims.
• Applications across domains:
  • Sports psychology focuses on how athletes approach performance, rituals, routines, and brain processes that optimize goals, jumps, timings, etc.
  • Psychology connects physical health, learning, and social interaction to broader real-world outcomes.
• The scientific aim: to study mental activity and health through evidence-based methods, reducing reliance on anecdote alone.
• The role of critical thinking to evaluate information (see below).

Psychology as a science: empiricism and critical thinking

• Psychology uses objective, evidence-based methods to study thoughts, feelings, and behaviors.
• Caution about popular psychology on social media:
  • Much of it is not empirically driven and can blame parents or other factors without robust evidence.
  • Evidence can contradict popular assumptions once studied properly.
• Critical thinking in psychology involves evaluating information to reach conclusions based on evidence.
• Three questions to ask about any information:
  • Is the source credible or believable?
  • Is there strong empirical evidence for the claim?
  • Do other people believe that this source is credible?
• Media literacy and synthesis of evidence:
  • Are there multiple evidence-based papers supporting a claim?
  • Is there a meta-analysis or a synthesis of many studies?
  • Do other credible sources agree with the claim?
• Credible sources in psychology:
  • Major organizations and journals include the Association for Psychological Science (APS) and the American Psychological Association (APA).
  • Credible work is usually produced by individuals with master’s degrees or doctorates and published in peer-reviewed venues.
• What peer review means:
  • An editor reviews a manuscript, and if accepted, it is sent to three reviewers who provide critical feedback.
  • The process often leads to substantial revisions, increasing the validity and reliability of the work.
  • Peer-reviewed sources are considered high-quality and credible.
• Distinguishing evidence from beliefs or opinions:
  • Intuition/gut feelings can be informative in some contexts but are not sufficient for major conclusions.
  • Beliefs are personal; opinions are judgments; both can be biased by culture and experience.
• Summary takeaway: credible psychology relies on empirically supported claims, replicated evidence, and consensus across multiple high-quality sources.

What guides psychology today? history, bias, and ethical reflection

• Early history and founding figures:
  • Wilhelm Wundt (as referenced in the transcript, though note the spelling in the talk) established the first psychology laboratory in 1879. (
    $1879$ )
  • The historical image in the talk shows a lack of women, Indigenous people, and people of color in the early field, highlighting the need to acknowledge bias and exclusion in the discipline’s origins.
• The careful reading of history: the founders often came from privileged backgrounds and their experiences shaped their questions and generalizations.
• Important caveat raised in the talk: much of history and theory in psychology over the past century has centered on white, Western perspectives; this shapes what gets studied and how conclusions are drawn.
• Influences of religion and culture:
  • Founders and early theorists sometimes drew on religious or cultural backgrounds to form their ideas.
  • It is essential to consider how these contexts influenced research questions and interpretations.
• Notable figures discussed and cautions about them:
  • Sigmund Freud: wealthy, Jewish, influential but many of his theories later lacked reliability under modern empirical testing; some elements have been revised or rejected.
  • Conrad Lorenz: known for imprinting in geese, but his work is tied to problematic political contexts (Nazi era) and eugenics; highlights the danger of separating scientific findings from ethical and political contexts.
  • Anna Freud and others who contributed, sometimes underrecognition due to historical biases in who received credit and who was allowed to practice or publish.
• Ethical and philosophical implications:
  • The statement: "the heartbeat of racism is denial" and the corollary: "confession is the heartbeat of anti-racism". Acknowledging past biases is essential to move forward.
  • Biases include racism, homophobia, sexism, ableism, and other prejudices that shaped research questions and interpretations.
  • Ethical reflections require holding both scientific findings (biological or psychological processes) and the social/historical context in which they were produced.
• The history is important for understanding current practice, but it is not the sole determinant of the discipline’s value or direction.

Domains of psychology and the department’s focal areas

• Biological domain:
  • Person mentioned: Dr. Christina Sorwell (neuroscience/biology focus).
  • Research questions involve how brain and body activity give rise to thoughts, feelings, and actions.
  • Methods include analyzing hormones (e.g., cortisol) and brain activity to understand stress and other states.
• Mental and physical health domain (clinical and counseling focus):
  • Dr. Rachel Kohler Mulholland: clinical psychologist; also involved in counseling; teaches courses on drug and alcohol counseling and relationships.
  • Dr. Heather Peters: sports psychologist; applies psychology to athletic performance and related areas.
• Social and personality domain:
  • Dr. Dennis Stewart: social psychologist; investigates how social factors and personal characteristics influence thoughts, feelings, and actions; involved in marketing-related questions about buying behavior.
• Cognitive domain:
  • Dr. Cheryl Stewart: cognitive psychologist; investigates what is happening in the brain to affect thoughts, feelings, and behavior.
• Developmental domain:
  • The instructor (the speaker) positions themselves as a developmental-focused psychologist, examining growth across the lifespan from birth to old age.
  • Emphasis on birth through death and how changes across life stages influence thoughts and behaviors.
• Note: The lecture mentions that there are more slides available beyond this excerpt.

Connections to the broader course and real world

• The material ties to everyday decision-making, health, relationships, education, marketing, sports, and technology.
• Key skills emphasized:
  • Critical thinking and media literacy to evaluate online claims and popular psychology.
  • Recognizing the role of empirical evidence and avoiding overreliance on single sources or anecdotes.
• Practical implications discussed:
  • In clinical settings, research helps us understand what factors contribute to infidelity, relationship strain, and other issues, guiding evidence-based interventions.
  • In marketing and consumer behavior, psychology informs how people make decisions and what motivates actions.
  • In sports, psychology informs routines, rituals, and strategies that contribute to performance.

Key concepts and terms to remember

• Psychology as both personal and scientific definitions:
  • Personal scope: subject areas like relationships and learning.
  • Scientific scope: understanding why we think, feel, and behave as we do, through evidence-based methods.
• Empiricism and evidence-based practice in psychology; contrast with non-empirical sources.
• Critical thinking questions for credibility:
  • Credible source? Strong evidence? Consensus among credible sources?
• Peer review process:
  • Editor → reviewers (typically 3) → revisions → publication; enhances validity.
• Common biases in historical psychology:
  • Representational bias: dominance of white Western perspectives; underrepresentation of women and people of color.
  • Ethical concerns: eugenics, nationalism, and dismissive attitudes toward marginalized groups.
• Major contemporary domains and the scholars associated with them (examples):
  • Biological/neuroscience: brain-body links, hormones (e.g., cortisol).
  • Clinical/counseling: mental health, relationships, addiction.
  • Sports psychology: performance enhancement and athletic mindset.
  • Social psychology/marketing: social factors and consumer behavior.
  • Cognitive psychology: mental processes underlying thinking and decision-making.
  • Developmental psychology: lifespan development from birth to old age.
