Conversion Disorder in AP Psychology: the definition, and what the exam actually asks.
Conversion disorder is a condition in which real physical symptoms, such as weakness, numbness, loss of sensation or episodes resembling seizures, are inconsistent with how the nervous system actually works. The American Psychiatric Association now lists it under the name functional neurological symptom disorder. But the conversion disorder AP Psychology definition comes with a catch: College Board’s framework never names the term, and it bounds the exam to ten categories of disorder that do not include it.
What conversion disorder means
Conversion disorder denotes physical symptoms affecting movement or the senses, in functions a person would normally control or feel. What defines the condition is not the symptom but the mismatch: the clinical picture is inconsistent with recognized neurological disease, and that inconsistency is something a clinician establishes positively, not by failing to find another explanation.
That framing is newer than most classroom material suggests. Older descriptions define the condition as physical symptoms with no organic cause, and require a psychological stressor that has been converted into bodily form. The current clinical definition drops the stressor requirement and rests on the inconsistency itself. Anything built on the older wording is describing a superseded form of the diagnosis.
One point survives every revision, and it is the one students most often miss: the symptoms are genuinely experienced, not deliberately produced. That is part of how the condition is defined, and it is what separates it from two of the terms further down.
What it is called now, and which manual says so
The name has moved twice, and the version students inherit usually gets the second move wrong.
In DSM-5, published in 2013, the American Psychiatric Association added functional neurological symptom disorder in parentheses after the older term, so the entry read Conversion Disorder (Functional Neurological Symptom Disorder). Conversion disorder was still the lead name. In the 2022 text revision, DSM-5-TR, the association reversed the two, so the entry now reads Functional Neurological Symptom Disorder (Conversion Disorder). Its published reasons for reversing them: the functional label is what the international research and patient community prefers, the older term is falling out of use among researchers and clinicians, and the older term is not neutral about cause.
Neither edition retired either name. Both carry both, one of them in parentheses. The widely repeated claim that DSM-5 replaced conversion disorder with functional neurological symptom disorder is wrong by one revision.
None of that comes from College Board. Its framework mentions the Diagnostic and Statistical Manual exactly once, at Essential Knowledge 5.3.A.3, with no edition number, and puts the World Health Organization’s International Classification of Mental Disorders beside it, noting only that both systems are revised as research and practice move on. That is the whole of what College Board says about diagnostic manuals, and it is why the DSM-5-TR change is credited here to the American Psychiatric Association and to nobody else.
What AP Psychology actually examines
College Board puts this material in Unit 5, Mental and Physical Health, and splits it across three topics. Topic 5.3 covers how psychological disorders are defined and explained, Topic 5.4 sets out which categories are in scope, and Topic 5.5 covers treatment. The unit carries 15 to 25 percent, and College Board prints that figure under its multiple-choice section heading, with all five units on the same band. Its student-facing course page prints the same range without the section qualifier, so the narrower reading is the one to carry.
Topic 5.3 gives three factors used to identify a psychological disorder: how far functioning is impaired, whether the person experiences distress, and how far the behavior departs from what the surrounding society treats as normal. It then sets out seven perspectives on cause, which are the behavioral, psychodynamic, humanistic, cognitive, evolutionary, sociocultural and biological, plus two interaction models, the biopsychosocial model and the diathesis-stress model. The behavioral perspective is the bridge back to learning theory: it locates the causes of mental disorders in maladaptive learned associations between responses and stimuli, and Topic 5.5 then has conditioning principles reappear as treatment, in applied behavior analysis. If the operant conditioning AP Psychology definition is still shaky, this is where it matters.
Topic 5.4 is where the scope boundary sits, and College Board draws it explicitly. The topic opens with an exclusion statement whose effect is that the exam draws only on the disorders the topic itself names, however many more a clinical manual might contain. Those categories are:
- Neurodevelopmental: attention-deficit/hyperactivity disorder, autism spectrum disorder.
- Schizophrenic spectrum: schizophrenia.
- Depressive: major depressive disorder, persistent depressive disorder.
- Bipolar: Bipolar I, Bipolar II.
- Anxiety: specific phobia, agoraphobia, panic disorder, social anxiety disorder, generalized anxiety disorder.
- Obsessive-compulsive and related: obsessive-compulsive disorder, hoarding disorder.
- Dissociative: dissociative amnesia, with and without fugue, and dissociative identity disorder.
- Trauma and stressor-related: posttraumatic stress disorder.
- Feeding and eating: anorexia nervosa, bulimia nervosa.
- Personality: three clusters, covering paranoid, schizoid and schizotypal; antisocial, histrionic, narcissistic and borderline; avoidant, dependent and obsessive-compulsive.
Conversion disorder is not among them. Neither is the somatic symptom class it belongs to: there is no somatic or somatoform heading anywhere in the framework.
The category it is actually confused with
Four terms sit close to conversion disorder in most textbooks, and none of them is examinable either. At the level of what the words denote: malingering is not a psychiatric disorder at all but a behavior, the deliberate production of symptoms for an external reward. Factitious disorder is the deliberate production of symptoms to occupy the patient role, without that external reward. Somatic symptom disorder covers symptoms that are real, where the distinguishing feature is the degree of distress attached to them, and illness anxiety disorder covers preoccupation with having an illness. Those distinctions are worth understanding, because they are what the older organization of this material rested on. Not one of the four appears in College Board’s framework.
The category that does appear, and the one this search is usually circling, is dissociative disorders. College Board lists them at 5.4.G, and names two: dissociative amnesia, with and without fugue, and dissociative identity disorder. It attributes the category to the experience of trauma or stress.
The reason the two get tangled is historical. Older textbooks shelved somatoform and dissociative disorders in the same chapter, so students arriving from that organization meet conversion disorder first and dissociative disorders second. On the current exam the order is reversed: the dissociative category is examinable and the somatoform one is not. If study time has to land somewhere near this topic, that is where it lands.
How the disorders material is tested
Section I is 75 multiple-choice questions, 90 minutes, and 66.7 percent of the exam score, mixing set-based questions with discrete ones. Disorders material typically arrives as a short scenario: a person’s experience is described and the question asks which of four conditions best fits it. College Board’s own published sample set works exactly that way, and the four options come from the categories Topic 5.4 names. That is the practical reason a term outside the list cannot be the answer.
Section II is two free-response questions, 70 minutes, and 33.3 percent of the score, with the two weighted equally at 16.65 percent each. The Article Analysis Question supplies one summarized peer-reviewed source, is worth 7 points, and allows 25 minutes including a 10-minute reading period. The Evidence-Based Question supplies three sources, is also worth 7 points, and allows 45 minutes including a 15-minute reading period.
The exam is fully digital in Bluebook, with both sections answered in the app. College Board states that on its student and teacher-facing pages rather than in the framework document, which does not mention Bluebook at all. The 2027 administration is Friday, May 14, in Session 2.
What to study instead
None of this says conversion disorder is not worth knowing. It says it is not worth exam preparation time, which is a different claim. A student meeting the term in a textbook, in a question bank built before the framework was revised, or in a psychology course outside AP has a real reason to understand it.
For the exam itself, two things pay. Work Topic 5.4’s ten categories until the disorders named under each come back without effort, because that list is the answer space for every scenario question in this unit. Then work Topic 5.3’s three identifying factors and seven perspectives, because those are what a scenario question is usually testing underneath the label. The rest of the AP Psychology key terms on this hub are organized on the same framework.

Frequently asked questions
Quick answers, checked against College Board.
Will conversion disorder ever appear on the AP Psychology exam?
Not as a correct answer drawn from College Board’s framework, because the framework does not name it anywhere. It can still turn up as a wrong option in third-party practice material written before the current framework, and it appears in plenty of textbooks that predate it. A practice question that turns on the term says the question bank is out of date; it does not say your preparation has a gap.
My textbook has a somatoform disorders chapter. Is it wrong?
It is not wrong; it is a different organization. Somatoform was the older grouping, and clinical manuals still carry a somatic symptom and related disorders class. What changed is what College Board examines: the current framework has no somatic or somatoform heading at all. The chapter is useful background and it is not on the syllabus.
Should I write functional neurological symptom disorder or conversion disorder?
For an AP answer the question does not arise, because the exam does not examine the category. Outside AP, the American Psychiatric Association’s current entry leads with functional neurological symptom disorder and keeps conversion disorder in parentheses, so the functional name is the safer default in anything written since 2022.
Does the older name matter for the free-response questions?
Less than students expect. Both free-response questions are built on summarized research, not on a vocabulary list. One supplies a single source and asks you to identify research elements in it; the other supplies three and asks you to build a claim across them. Neither is a definitions exercise.
