PSY-355 at Southern New Hampshire University studies the fundamental principles of social psychology and how social interaction connects to social influence.
The catalog says students analyze differences in social patterns, study the dynamics of intergroup relationships, conflict and cooperation, and learn the limits of generalizing psychological research to cultural, gender, ethnic or age groups.
PSY-108 is the listed prerequisite. Students find the course challenging because theories are named after classic experiments and because good answers must also question who the research was done on.

What PSY-355 Covers
The catalog gives three main areas.
| Area | What to focus on |
|---|---|
| Social interaction and influence | How other people shape our thoughts, feelings and actions, including conformity and persuasion |
| Social patterns and group differences | How patterns vary across contexts and groups |
| Intergroup relationships | Conflict, cooperation, prejudice and ways of improving relations |
| Limits of generalization | Whether findings apply across cultural, gender, ethnic or age groups |
Key Ideas Explained
Situation and Person
Social psychology often shows that situations matter more than people expect. Explain how a setting shapes behavior, then ask which people it affects most and why.
Illustration: A workplace team goes along with a flawed plan. A conformity reading looks at pressure to agree and the absence of a dissenting voice. A group decision-making reading looks at how discussion can strengthen the initial view. Choosing between them depends on details in the case.
Intergroup Relations
Understand how categorizing people into groups can fuel bias, and what conditions research links with reducing conflict, such as shared goals.
Generalisability
Many classic studies used narrow samples. State who took part, where, and what that means for the claim.
Typical Assignments and How to Approach Them
The catalog does not list graded assessments. These are common kinds of work in a theory-based course; confirm yours in the course.
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Discussion posts | Applying theory to events | Name the theory, link it to specifics, say what it cannot explain |
| Theory application papers | Using concepts to analyze a situation | Use two theories, compare them, reach a conclusion |
| Research critiques | Evaluating classic or recent studies | Cover design, sample, ethics and generalisability |
| Reflections on diversity | Considering cultural limits | Tie reflections to evidence rather than assumptions |
Where Students Get Stuck
- Retelling the experiment. Use the study as evidence for a point, not as a story.
- Ignoring sample limits. Always ask who took part.
- Stereotyping. Avoid generalizations about groups; cite evidence.
- Mixing up similar theories. Keep a table of each theory, its claim and an example.
- Ethics blind spots. Be able to discuss why some classic studies would not be run today.
Applying a Theory to a Case
| Step | Action | Check |
|---|---|---|
| Describe the situation | Who, where and what happened | Facts only |
| Select theories | Two that offer different explanations | Do they lead to different predictions? |
| Apply | Explain how each fits the details | Do you use specifics from the case? |
| Evaluate | Strengths and limits, including sample issues | Have you addressed generalization? |
| Conclude | Which explanation is stronger | Is it qualified, not absolute? |
Questioning Classic Studies
Classic social psychology studies are memorable, but instructors want you to go beyond retelling them. Ask four questions: who took part, how was behavior measured, would the result hold elsewhere, and was the study ethical by today’s standards?
Answering these in a short paragraph gives you critical thinking marks quickly. It also meets the catalog’s point about the limits of generalizing findings to different cultural, gender, ethnic or age groups.
Linking Theory to Everyday Events
Instructors often ask for contemporary examples. Pick an event you can describe factually, such as how a community responded to a local change, and apply one theory to one part of it.
Say what the theory predicts, what actually happened and whether the match is close. When the match is poor, that is useful too: explain what the theory leaves out, which links straight to the catalog’s point about the limits of generalizing research.
Avoid examples that depend on stereotypes about a group. If an event involves a group, describe the situation and the behavior, then use evidence to explain it, rather than assuming what members of the group are like.
Study Tips for PSY-355
- Keep a table of theory, key study, claim and critique.
- Practice summarizing each study in three sentences.
- Ask who the participants were in each study.
- Link ideas to current events, but support them with research.
- Review the ethics of classic experiments.
- Use clear subheadings in longer papers.
