Learning Targets
3-1 Explain the difference between basic and applied psychology.
3-2 Describe what psychologists working in various subfields do, and where they work.
Basic terms:
- psychometrics: the scientific study of the measurement of human abilities, attitudes, and traits.
- basic research: pure science that aims to increase the scientific knowledge base.
- applied research: scientific study that aims to solve practical problems.
- clinical psychology: a branch that studies, assesses, and treats people with psychological disorders.
- counseling psychology: a branch that assists people with problems in living (often related to school, work, or marriage) and in achieving greater well-being.
- psychiatry: a branch of medicine dealing with psychological disorders; practiced by physicians licensed to prescribe drugs and provide medical treatments.
- community psychology: a branch that studies how people interact with their social environments and how social institutions affect individuals and groups.
- I/O psychology (industrial-organizational): applying psychology to optimize human behavior in workplaces (e.g., selection, training, morale, productivity).
- human factors psychology: explores how people and machines interact and how environments can be made safe and easy to use.
- other subfields include cognitive, developmental, educational, personality, social, experimental, and psychometric/quantitative psychology.
The field is a hub for many disciplines. Psychology is described as a "hub scientific discipline" (John Cacioppo, 2007), a meeting ground for diverse interests.
The common quest across subfields: describing and explaining behavior and the underlying mechanisms.
Psychometrics and quantitative methods shape how we measure abilities, attitudes, and traits; statistics and data analysis underpin many subfields.
There is a continuum from basic research (to build knowledge) to applied research (to solve real-world problems) to the helping professions (to assist people directly).
Real-world pictures of subfield work mentioned in the text:
- A chemist at work vs a psychologist at work (lab scientist vs brain research).
- An intelligence researcher measuring infant boredom by tracking looking behavior.
- An executive evaluating a new training program for employees.
- A researcher analyzing big data from social media updates.
- A therapist actively listening to a depressed client.
- A traveling academic visiting another country to share ideas.
The quote about psychology as a science and a helping profession:
- Psychology experiment: testing, observing, and helping modify behavior across settings.
- The text emphasizes both scientific study and clinical/helping roles.
Dorothea Dix is cited as a historical reformer who advocated humane treatment of those with psychological disorders (1802–1887). Example quote: '…call your attention to the state of the insane Persons confined within this Commonwealth, in cages.'
Psychology's Main Subfields
If you major in psychology, you develop a scientific mindset and awareness of core principles (biological bases, nature–nurture interactions, lifespan development, cognition, disorders, and social interactions).
Career pathways span business, helping professions, health services, marketing, law, sales, and teaching; graduate school enables specialized training.
Appendix D (Preparing for Further Psychology Studies) provides tips for bachelor’s, master’s, or doctoral training and career options.

- Community psychology
- Role: studies how people interact with social environments and how institutions affect individuals and groups; aims to create healthy environments
AP® Exam Tips and Notes
- Important distinction: psychiatry is a medical specialty.
- You should be able to summarize similarities and differences among counseling psychologists, clinical psychologists, and psychiatrists for the AP® exam.
- Check Your Understanding (sample):
- 1. Clinical psychology
- 2. Psychiatry
- 3. Community psychology
- a. Works to create social and physical environments that are healthy for all.
- b. Studies, assesses, and treats people with psychological disorders but usually does not provide medical therapy.
- c. Branch of medicine dealing with psychological disorders.
- Answers: 1 -> b; 2 -> c; 3 -> a
- FYI note: Expect questions on career options and the division between basic subfields, applied subfields, and helping professions.
- The subfields listed here are arranged alphabetically in the text; graduate training typically required for many roles.

Delusional Disorder: Diagnostic Criteria (DSM-5) and Specifiers
- Diagnostic criteria for Delusional Disorder (DSM-5, code 297.1):
- A. Nonbizarre delusions that persist for at least (e.g., being followed, poisoned, infected, loved at a distance, deceived by a partner, or having a disease)
- B. Criterion A for Schizophrenia has never been met
- C. Apart from the impact of the delusion(s) or its ramifications, functioning is not markedly impaired and behavior is not obviously odd or bizarre
- D. If mood episodes have occurred concurrently with delusions, their total duration is brief relative to the duration of the delusional periods
- E. The disturbance is not due to the direct physiological effects of a substance or a general medical condition
- Delusional themes (specifier types):
- Erotomanic Type: Delusions that another person, usually of higher status, is in love with the individual
- Grandiose Type: Delusions of inflated worth, power, knowledge, identity, or a special relationship to a deity or famous person
- Jealous Type: Delusions that the individual's sexual partner is unfaithful
- Persecutory Type: Delusions that the person or someone close is being malevolently treated
- Somatic Type: Delusions that the person has a physical defect or medical condition
- Mixed Type: Delusions characteristic of more than one type but no single theme predominates
- Unspecified Type: No theme specified
- Note: The content includes a historical image/placeholders (e.g., Ted Fitzgerald/AP Images) and is intended to illustrate DSM criteria in a clinical context.
Connections to Foundational Principles and Ethics
- Basic and applied psychology connect to core principles of science:
- Empirical observation, measurement, and hypothesis testing underpin all subfields.
- Consideration of biological bases, cognitive processes, social influences, and lifespan development.
- Real-world relevance:
- Informing educational policy (developmental, educational psychology)
- Designing safer and more usable technologies (human factors, I/O, cognitive engineering)
- Improving mental health care and access (clinical, counseling, community psychology; policy implications from reformers like Dix)
- Ethical implications:
- Use of psychological tests (psychometrics) must ensure validity, fairness, and privacy.
- Forensic psychology raises questions about the role of psychology in legal settings and potential biases.
- Community psychology emphasizes social justice and creating healthier environments for diverse populations.
Notes on Terminology and Structure
- Psychology's subfields can be broadly categorized into:
- Basic Research Subfields: focus on knowledge generation
- Applied Research Subfields: apply findings to real-world problems
- The Helping Professions: clinical and counseling practices, plus related roles in health and community work
- The text emphasizes the versatility of a psychology degree and the wide range of work settings, including universities, schools, clinics, government agencies, businesses, and non-profits.
