General Psychology: Core Concepts, Theories & Principles
Ten questions. Ten topic areas. Thirty minutes. Sensation and perception, motivation, cognitive biases, psychological disorders, research ethics, persuasion, memory, human development, defense mechanisms, and social influence. Each topic has specific concepts that show up in MCQs time and again — and knowing the exact vocabulary is what separates a correct answer from a close-but-wrong one. Here’s how to approach each area.
Ten different topic areas in one quiz is a lot of ground. The exam isn’t testing depth on any one subject — it’s testing breadth. That means you need a working understanding of ten distinct concepts, not a deep dive into two or three. MCQ assessments at this level are heavily dependent on knowing the right vocabulary. The difference between a correct answer and a trap option is often a single word. That’s the game being played here.
What This Guide Covers
How This MCQ Format Actually Tests You
One question per topic. That’s the structure here. Each of the ten questions targets a different area, which means there’s no topic you can safely skip. A 30-minute limit on ten questions gives you about three minutes per question — which is plenty of time if you know the material. It’s not enough time to reason your way from scratch through something you haven’t studied.
Vocabulary Recognition, Concept Application, and Distinguishing Between Similar-Sounding Terms
Most psychology MCQ questions at the introductory level fall into one of three categories: recall (what is the term for X?), application (which concept explains this scenario?), and discrimination (which of these is NOT an example of Y?). The third type — discrimination — is where students lose the most points. Two answer options will look almost identical. The distinction is always in the precise definition of the terms involved.
The trap option pattern in psychology MCQs: Question writers often pair the correct answer with a closely related but incorrect term from the same topic area. For sensation and perception questions, “absolute threshold” and “difference threshold” are a classic pairing. For memory, “encoding” and “retrieval” can both look correct depending on the scenario. Knowing not just what each term means but when it applies is what resolves those traps.All Ten Topics at a Glance

Topic 1 — Sensation & Perception
These two terms are related but not the same. That distinction is almost always what the question is testing. Sensation is the detection of stimuli by sensory receptors — the raw signal. Perception is the brain’s active interpretation of that signal into something meaningful. One is passive input; the other is active construction.
Threshold Concepts, Processing Directions, and Sensory Adaptation
The absolute threshold is the minimum intensity needed to detect a stimulus 50% of the time. The difference threshold (or just-noticeable difference, JND) is the smallest change in intensity that can be detected. These are distinct — one is about detecting something at all; the other is about detecting change.
Bottom-up processing starts with raw sensory data and builds up to perception — no prior knowledge shapes it. Top-down processing works the other way: expectations, context, and prior experience shape what you perceive. A blurry image that suddenly “clicks” into recognizable form because you know what you’re looking for — that’s top-down. Sensory adaptation is the reduced sensitivity to a constant, unchanging stimulus over time — why you stop noticing the smell of your own perfume within minutes of applying it. All three are common MCQ targets.Topic 2 — Motivation
Motivation questions almost always involve matching a scenario to a specific theory. Know Maslow. Know the difference between intrinsic and extrinsic. And know drive-reduction theory — it comes up more often than students expect.
Maslow’s Hierarchy — The Order Matters
From base to top: physiological needs → safety → love/belonging → esteem → self-actualization. Questions often describe a scenario and ask which need is being addressed. The catch: deficiency needs (the bottom four) are different in nature from growth needs (self-actualization). You need the lower levels met before the higher levels become motivating — that’s the functional claim the theory makes.
Intrinsic vs. Extrinsic — and the Overjustification Effect
Intrinsic motivation comes from within — interest, enjoyment, personal satisfaction. Extrinsic comes from outside — grades, money, praise. The overjustification effect is a classic MCQ target: when you start rewarding someone extrinsically for something they previously enjoyed intrinsically, their intrinsic motivation often decreases. That effect has a name. Know it.
Topic 3 — Cognitive Biases
There are dozens of cognitive biases. The ones that show up in introductory psychology MCQs are a smaller, consistent set. Know these specifically.
| Bias / Heuristic | What It Describes | Classic Example |
|---|---|---|
| Confirmation Bias | Seeking or interpreting information in ways that confirm existing beliefs | Only reading news sources that agree with your political views |
| Availability Heuristic | Judging likelihood based on how easily examples come to mind | Overestimating plane crash risk after media coverage of an accident |
| Representativeness Heuristic | Judging probability based on how much something resembles a prototype | Assuming a quiet, bookish person is a librarian rather than a salesperson |
| Fundamental Attribution Error | Overemphasizing internal traits and underemphasizing situation when explaining others’ behavior | Assuming a driver who cut you off is aggressive, ignoring that they may be rushing to a hospital |
| Anchoring Bias | Over-relying on the first piece of information encountered | A $500 jacket seems reasonable after seeing a $1,200 one first |
| Hindsight Bias | Believing, after an event, that you knew it would happen all along | “I knew that team was going to lose” — said after the game |
Topic 4 — Psychological Disorders
The most important framing concept here is the biopsychosocial model — the idea that psychological disorders result from an interaction of biological, psychological, and social factors. That’s the dominant perspective in modern clinical psychology, and it’s the one MCQs test most often at the introductory level.
Classification, Criteria, and Distinguishing Between Disorder Categories
Questions typically ask you to identify which disorder category fits a described set of symptoms, or to name a criterion that applies to all psychological disorders. The DSM-5 standard definition requires that symptoms cause significant distress or impairment in social, occupational, or other important areas of functioning. “Unusual” or “different” behavior alone is not a disorder — impairment or distress is the key criterion.
Category distinctions to know: Anxiety disorders (characterized by excessive fear or worry — GAD, phobias, panic disorder). Mood disorders (major depressive disorder, bipolar disorder — affect is the central feature). Psychotic disorders (schizophrenia — hallucinations, delusions, disorganized thinking). Obsessive-compulsive and related disorders (OCD — distinct category in DSM-5, no longer classified under anxiety). Trauma-related disorders (PTSD — also separated from anxiety disorders in DSM-5). These reclassifications are common trap areas in MCQs.Topic 5 — Research Ethics
Psychology has some infamous ethical violations in its history — Milgram’s obedience studies, Watson’s Little Albert experiment, Zimbardo’s Stanford Prison Experiment. Those violations are why current ethical standards exist. MCQ questions in this area often reference those standards directly.
Informed Consent: Participants must be told the nature of the study, what participation involves, and that it’s voluntary — before they agree to participate. Cannot be waived except under specific conditions.
Right to Withdraw: Participants can leave a study at any time without penalty. Milgram’s study violated this in practice — participants were pressured to continue when they wanted to stop.
Deception: Sometimes permitted, but only when no other method is feasible and the deception won’t cause lasting harm. Must always be followed by debriefing.
Debriefing: After a study — especially one involving deception — participants must be fully informed about the study’s true purpose and any deception used. Required, not optional.
Confidentiality: Participant data must be kept private. Anonymity (identity not recorded) is stronger than confidentiality (identity recorded but protected).
Topic 6 — Persuasion
Two frameworks dominate psychology MCQs on persuasion: the Elaboration Likelihood Model (ELM) and Cialdini’s six principles of influence. Know both.
Central Route vs. Peripheral Route — and When Each Applies
The central route to persuasion works through careful, logical analysis of arguments. It requires high motivation and ability to process. The peripheral route works through mental shortcuts — the speaker’s attractiveness, their credentials, the emotional tone of the message. Attitude change through the central route tends to be more durable and resistant to counter-persuasion. The peripheral route produces faster but less stable attitude shifts.
Cialdini’s six principles: Reciprocity (we feel obligated to return favors), Commitment/Consistency (we behave consistently with prior commitments), Social Proof (we look to others when uncertain), Authority (we defer to experts), Liking (we’re more easily persuaded by people we like), and Scarcity (we value things more when they’re rare). MCQ questions usually describe a scenario and ask which principle is being applied. The foot-in-the-door technique (start with a small request, then escalate) works through commitment/consistency. The door-in-the-face technique (start with a large request, then retreat to a smaller one) works through reciprocity and contrast.Topic 7 — Memory
Memory questions at the introductory level almost always involve the three-stage model: encoding → storage → retrieval. The question is usually: which stage failed? Or: which type of memory is being described?
The Three Memory Stores
- Sensory memory: Very brief (less than a second for iconic/visual, a few seconds for echoic/auditory); holds raw sensory input before attention filters it
- Short-term / working memory: About 20–30 seconds without rehearsal; limited capacity (~7±2 chunks per Miller’s Law); active processing happens here
- Long-term memory: Potentially unlimited capacity and duration; includes explicit (declarative) and implicit (procedural, classical conditioning) memory
Forgetting — The Most Tested Memory Subtopic
- Proactive interference: Old learning disrupts new learning — prior Spanish vocabulary interferes when learning French
- Retroactive interference: New learning disrupts recall of old learning — new phone number makes you forget the old one
- Retrieval failure: Information is in long-term memory but can’t be accessed — tip-of-the-tongue phenomenon
- Encoding failure: The information was never properly stored in the first place
Topic 8 — Human Development
Two theorists dominate MCQ questions here: Piaget (cognitive development) and Erikson (psychosocial development). Know both stage sequences and what psychological crisis or cognitive achievement each stage involves.
Sensorimotor → Preoperational → Concrete Operational → Formal Operational
The sensorimotor stage (0–2 years) is defined by object permanence — understanding that objects exist even when out of sight. The preoperational stage (2–7) is characterized by symbolic thinking but egocentrism — inability to take another’s perspective. The concrete operational stage (7–11) brings conservation — understanding that quantity stays constant despite changes in appearance. The formal operational stage (12+) enables abstract reasoning and hypothetical thinking.
Erikson’s key stages for MCQs: Trust vs. Mistrust (infancy — does the world feel safe?), Autonomy vs. Shame/Doubt (toddler — can I do things independently?), Identity vs. Role Confusion (adolescence — who am I?), Intimacy vs. Isolation (young adulthood — can I form close relationships?), Generativity vs. Stagnation (middle adulthood — am I contributing?), Integrity vs. Despair (late adulthood — was my life meaningful?). Questions usually describe a life stage and ask which Eriksonian conflict applies.Ainsworth’s attachment types: Secure, anxious-ambivalent (anxious-resistant), avoidant, and disorganized. Secure attachment is associated with a caregiver who is consistently responsive. Know what the Strange Situation experiment was — it’s often referenced in scenario-based questions.
Topic 9 — Defense Mechanisms
Defense mechanisms come from psychoanalytic/psychodynamic theory — specifically Freud, later elaborated by Anna Freud. MCQ questions in this area almost always work by describing a behavior and asking which defense mechanism it represents. The challenge: several mechanisms look similar. Precise definitions matter here more than anywhere else in this assessment.
Repression vs. Suppression: Repression is unconscious — the memory is pushed out of awareness without deliberate effort. Suppression is conscious — you deliberately try not to think about something. MCQs test this distinction directly.
Rationalization vs. Intellectualization: Rationalization is creating a logical-sounding excuse for behavior motivated by something less acceptable. Intellectualization is using abstract reasoning to emotionally distance yourself from a distressing topic — thinking analytically about cancer prognosis rather than experiencing grief.
Displacement vs. Projection: Displacement redirects feelings toward a safer target (anger at your boss → snapping at your family). Projection attributes your own unacceptable feelings to someone else (you’re angry at someone but believe they’re angry at you).
| Defense Mechanism | Core Description | Quick Identifier |
|---|---|---|
| Repression | Unconsciously blocking threatening thoughts from awareness | Forgetting childhood trauma with no deliberate effort |
| Denial | Refusing to acknowledge a painful reality | “I don’t have a drinking problem” despite clear evidence |
| Projection | Attributing own unacceptable feelings to others | Feeling hostility but believing others are hostile toward you |
| Rationalization | Creating justifications for behavior driven by unconscious motives | “I didn’t want that job anyway” after rejection |
| Displacement | Redirecting emotional impulse from original target to a safer one | Kicking the dog after a hard day at work |
| Sublimation | Channeling unacceptable impulses into socially acceptable activities | Aggressive impulses redirected into competitive sport |
| Reaction Formation | Expressing the opposite of the true feeling | Treating a disliked colleague with exaggerated friendliness |
| Regression | Reverting to behavior typical of an earlier developmental stage | An adult throwing a tantrum under extreme stress |
Topic 10 — Social Influence
This is one of the richest areas in all of introductory psychology — and it maps directly to classic studies that are almost always referenced in MCQs. Know Asch. Know Milgram. Know the situational factors that increase or decrease both conformity and obedience.
Asch on Conformity. Milgram on Obedience. Different Things.
Asch’s line studies showed that people will give an obviously wrong answer to match the group consensus — even when the correct answer is visually obvious. About 75% of participants conformed at least once. Conformity here was driven by normative social influence — wanting to be accepted. Milgram’s obedience studies showed that a large proportion of ordinary people would administer what they believed were dangerous electric shocks to another person simply because an authority figure instructed them to. About 65% went to the maximum level.
Normative vs. informational influence: Normative influence is conforming to be liked or accepted. Informational influence is conforming because you genuinely believe others know better — common in ambiguous situations. Both are on exam radar.Groupthink: When a cohesive group prioritizes harmony over accurate analysis. Symptoms include suppressing dissent, illusion of unanimity, and self-censorship. Different from group polarization — where group discussion makes individual positions more extreme in whichever direction they were already leaning.
Social loafing vs. social facilitation: Social facilitation is improved performance on simple/well-learned tasks in the presence of others. Social loafing is reduced effort when working in a group, often because individual contributions are less identifiable. Both involve the presence of others, but in opposite directions — a classic MCQ pairing.
How to Work Through Each Question in 30 Minutes
You have about three minutes per question. That’s comfortable — unless you don’t recognize the topic. Here’s how to move efficiently through a quiz like this.
Read the Question Stem — Identify the Topic First
Before you look at the answer options, read the question and identify which of the ten topics it’s testing. This primes your recall for that specific vocabulary cluster. Answer options are designed to be distractors — loading your mind with the right conceptual framework before you read them reduces the chance a trap option fools you.
Eliminate Clearly Wrong Answers First
In a well-constructed four-option MCQ, at least one answer is clearly wrong and one is a plausible distractor. Eliminate the clear wrong answer immediately. Then focus your decision between the remaining two. This is the most reliable MCQ technique regardless of subject area — it narrows the cognitive load and improves accuracy.
Watch for Qualifier Words in the Stem
Words like “most likely,” “best describes,” “NOT,” and “except” change what the question is asking entirely. “Which of the following is NOT an example of…” inverts the task. Missing that word means choosing the opposite of the correct answer. Read the full question stem twice before selecting.
If You’re Unsure — Go With Your First Instinct on Factual Questions
Research on test-taking consistently shows that changing answers on factual recognition questions (as opposed to reasoning questions) reduces accuracy more often than it improves it. On a psychology vocab MCQ, if your first instinct was “confirmation bias” and you’re second-guessing between that and “availability heuristic,” trust the first read unless you can articulate a specific reason to change.
What Gets Students Into Trouble on This Assessment
Confusing Sensation and Perception
Treating them as interchangeable is one of the most common first-chapter errors in introductory psychology. A question describing the brain’s active interpretation of sensory input is always perception — not sensation.
Use a Simple Test: Detection or Interpretation?
Ask yourself: is the question describing the initial detection of a stimulus by receptors (sensation), or the mental process of giving it meaning (perception)? That split resolves nearly every sensation/perception MCQ.
Mixing Up Proactive and Retroactive Interference
The directions of these two are easy to flip. Students often pick the wrong one on scenario questions because they remember the terms but not which direction each runs.
Use a Memory Anchor: Pro = Old Interferes With New
Proactive = forward-acting. Old information acts forward to interfere with new learning. Retroactive = backward-acting. New information acts backward to disrupt recall of old material. Build a phrase to hold that direction.
Conflating Displacement and Projection
Both involve misdirected emotions — but displacement moves the emotion to a different target, while projection attributes the emotion to another person entirely. Students mix these up more than any other defense mechanism pair.
Anchor Each on the Direction of Movement
Displacement = same feeling, different person/object as target. Projection = same situation, but you assign your feeling to the other person — they become the one “having” the feeling you can’t accept in yourself.
Thinking Milgram Studied Conformity
Milgram studied obedience to authority. Asch studied conformity to social pressure. Both involve going along with others — but the mechanisms and contexts are completely different. Conflating them loses the question every time.
Anchor the Distinction: Asch = Peers, Milgram = Authority
In Asch, you’re conforming because of group pressure from peers. In Milgram, you’re obeying because someone with authority instructs you. The social dynamic is different — and that difference is always the point of the question.

The ten topics in this assessment don’t overlap much. Each question is essentially its own mini-test. That means you can’t rely on knowing one area deeply to carry you through — you need a working vocabulary across all ten. Thirty minutes is not the constraint here. Recognition is.
Run through the table of defense mechanisms one more time before you start. Know which direction proactive and retroactive interference each run. Make sure you can anchor Asch to conformity and Milgram to obedience without hesitation. Those are the specific confusions that show up most consistently in introductory psychology MCQs — and they’re entirely avoidable with clean definitions attached to the right names.
If you get to a question and two options both look reasonable, slow down. The question writer put both there on purpose. Ask yourself what the precise distinction is between the two terms. Usually, one of them perfectly matches the scenario and the other matches a different scenario you can mentally construct. That specificity is what the correct answer is built on.
