PSY-108: Introduction to Psychology

A study guide to SNHU's PSY-108, the first psychology course for most majors and the prerequisite for much of what follows.

Updated October 2026 · 5 min read

PSY-108 at Southern New Hampshire University introduces psychology as the science of why people think, feel and act as they do.

SNHU's catalog describes a course that traces the early schools of thought, the major branches and the core theories guiding contemporary psychology, built around the idea that psychology is everywhere in the human experience.

The course has no listed prerequisite and is itself the listed prerequisite for many later SNHU psychology courses, so what you learn here is reused again and again.

Students often find it harder than its title suggests. The vocabulary is broad, the theories overlap, and instructors expect you to apply a concept to a realistic situation rather than recite a definition.

What PSY-108 Covers

The catalog description points to three strands. Most assignments draw on one or more of them.

StrandWhat it means in practice
Early schools of thoughtHow structuralism, functionalism, psychoanalysis, behaviorism and humanism framed different questions about the mind
Major branchesAreas such as biological, cognitive, developmental, social, clinical and personality psychology, and how their methods differ
Core theoriesWell-known explanations of learning, memory, motivation, emotion, development and behavior, and the evidence offered for each
Psychology in daily lifeUsing a concept to interpret a real situation such as habits, stress, relationships or decisions

Your own module list will name the specific readings. Use the table above as a frame for organizing notes: for each topic, write what the idea claims, who proposed it, what evidence supports it and one everyday example.

Key Ideas Explained

Comparing Perspectives

A recurring skill is explaining one behavior through more than one lens. Biological, cognitive, behavioral and sociocultural explanations of the same event often differ, and strong answers say what each can and cannot explain.

Illustration: A student keeps putting off assignments. A behavioral reading looks at what is being reinforced (the relief of avoiding the task). A cognitive reading looks at thoughts such as "I work better under pressure". A biological reading might consider sleep or stress. Setting the three side by side shows you understand that no single theory owns the explanation.

Evidence, Not Opinion

Psychology is presented as a science, so claims need support. Distinguish a theory (an organized explanation) from a finding (a result from a study) and from a personal opinion. Instructors reward answers that name the idea, give a short example and link it to the question asked.

Nature and Nurture

Introductory courses keep returning to how inheritance and environment interact. Avoid presenting it as a contest. A balanced answer explains how both contribute and why researchers study them together rather than separately.

Typical Assignments and How to Approach Them

The catalog does not list graded assessments, so the table describes the kinds of work introductory psychology courses usually set. Check your own course page for exact requirements.

Assignment typeWhat it testsHow to approach it
Discussion postsApplying concepts and engaging with peersDefine the term in a sentence, apply it to a concrete case, then reply to a classmate with a specific point
Short applied papersUsing theory to interpret behaviorState your thesis early, use two or three concepts, tie each paragraph back to the prompt
ReflectionsConnecting course ideas to experienceDescribe the experience briefly, then spend most of the space analyzing it with course concepts
Quizzes or knowledge checksVocabulary and core theoriesBuild a glossary grouped by school of thought and test yourself on who argued what

Where Students Get Stuck

Planning an Applied Paper

StageWhat to doCheck
Read the promptUnderline the verbs (explain, apply, compare) and list the concepts requiredDoes your outline answer every verb?
Pick the conceptsChoose two or three that fit the situation bestCan you explain each in one sentence?
Find evidenceUse course readings first, then library sourcesIs every claim backed by a source?
DraftOne idea per paragraph, example in eachDoes each paragraph link to the thesis?
ReviseCut repetition, fix citations, read aloudDoes it fit the rubric?

Writing a Strong Discussion Post

Discussion posts are where many PSY-108 marks are earned or lost. A reliable pattern is claim, concept, example, limit. Open with your point in one sentence, name the concept that supports it, apply it to a specific situation, and finish by noting what the concept cannot explain.

Replies to classmates work best when they add something: a different theory, a question about the evidence or a further example. A reply that only agrees rarely shows the skills the course is built to develop.
