Negative Symptoms in AP Psychology
In AP Psychology, negative symptoms are the reduction or absence of normal behaviors and functions, such as diminished emotional expression (flat affect), reduced motivation (avolition), decreased speech (alogia), loss of pleasure (anhedonia), and social withdrawal. They are one of the five symptom areas of schizophrenia spectrum disorders.
This definition is part of Fiveable's AP Psychology review, which also has guided practice questions.
What are Negative Symptoms?
Negative symptoms are things that should be there but are missing or turned way down. Think of a healthy person's normal emotional expression, drive, speech, and social life as a volume dial. Negative symptoms turn that dial toward zero. Common examples are diminished emotional expression (often called flat affect), avolition (little motivation to start or finish tasks), alogia (very little speech), anhedonia (reduced ability to feel pleasure), and social withdrawal.
In the CED, negative symptoms are one of the five areas that define schizophrenic spectrum disorders. The other four are delusions, hallucinations, disorganized thinking or speech, and disorganized motor behavior. The CED labels those first three explicitly as positive symptoms. Here's the simple way to remember it. Positive symptoms add something that isn't normally there (voices, false beliefs). Negative symptoms subtract something that normally is there (emotion, motivation, speech).
Why Negative Symptoms matter in AP® Psychology
Negative symptoms live in Unit 5: Mental and Physical Health, under Topic 5.4, Selection of Categories of Psychological Disorders. They directly support learning objective AP Psych 5.4.B, which asks you to describe the symptoms and possible causes of selected schizophrenic spectrum disorders. The essential knowledge names negative symptoms as one of the five symptom areas, so you need to be able to recognize them in a case description. You also need to tell them apart from positive symptoms. They matter beyond schizophrenia too. Several of the same "missing" behaviors (low motivation, loss of pleasure, emotional flatness) show up in depressive disorders (5.4.C) and some personality disorders (5.4.J). That overlap is why the exam likes to test whether you can pick the right diagnosis from a full symptom picture.

Positive Symptoms of Schizophrenia (Unit 5)
Positive and negative symptoms are two halves of the same schizophrenia profile in 5.4.B. Delusions, hallucinations, and disorganized speech are additions to normal experience. Negative symptoms are subtractions from it. A single patient can have both, and exam vignettes often mix them so you have to sort each symptom into the right bucket.
Anhedonia and Major Depressive Disorder (Unit 5)
Loss of pleasure and low motivation look a lot like depression (5.4.C). The difference is context. In schizophrenia, these deficits appear alongside psychotic features like hallucinations or delusions. In major depressive disorder, they come with a sad, empty, or irritable mood and no psychosis.
Antipsychotic Treatment Outcomes (Unit 5)
Negative symptoms are often the stubborn ones. A classic exam scenario shows a patient whose hallucinations fade on an atypical antipsychotic while flat affect, minimal speech, and low motivation stick around. The takeaway is that the two symptom types don't always respond to treatment the same way.
Cluster A Personality Disorders (Unit 5)
Schizoid personality disorder, in the odd or eccentric Cluster A (5.4.J), involves emotional coldness and social detachment that can resemble negative symptoms. The key difference is that a personality disorder is an enduring, stable pattern starting in adolescence or early adulthood, without the hallucinations or delusions of schizophrenia.
Are Negative Symptoms on the AP® Psychology exam?
Negative symptoms show up mostly in multiple-choice vignettes. You'll read about a person and need to identify which behaviors are negative symptoms, or use the full symptom set to name the disorder. Typical setups include a patient with reduced emotional expression, minimal speech, and lack of motivation. Another common one is a clinician describing hallucinations, delusions, disorganized speech, and negative symptoms lasting six months with declining functioning, where you choose schizophrenia. Some questions add a treatment twist. For example, hallucinations shrink on an atypical antipsychotic but negative symptoms persist, and you have to explain why. Watch for distractor items that describe only positive symptoms (special messages from the TV, voices commenting, a belief in a government brain chip) and ask you to label them correctly. No released FRQ has used this term verbatim. Still, an FRQ asking you to apply schizophrenia symptoms to a scenario would reward naming a specific negative symptom and tying it to a concrete behavior in the prompt.
Negative Symptoms vs Positive Symptoms
"Positive" does not mean good, and "negative" does not mean bad. Both are harmful. Positive symptoms are additions to normal experience, like delusions (false beliefs), hallucinations (false perceptions), and disorganized speech. Negative symptoms are subtractions, like flat affect, avolition, alogia, anhedonia, and social withdrawal. Quick test: if the person is experiencing something healthy people don't, it's positive. If they're missing something healthy people have, it's negative.
Key things to remember about Negative Symptoms
Negative symptoms are normal behaviors and functions that are reduced or missing, such as emotional expression, motivation, speech, pleasure, and social engagement.
Negative symptoms are one of the five symptom areas of schizophrenic spectrum disorders listed under AP Psych 5.4.B.
Positive symptoms add something abnormal, like hallucinations or delusions, while negative symptoms take away something normal.
Flat affect, avolition, alogia, and anhedonia are the specific negative symptoms you should be able to spot in a vignette.
Negative symptoms can persist even after medication reduces positive symptoms like hallucinations.
Because loss of pleasure and motivation also appear in depression, the presence of psychotic features is what points you toward schizophrenia.
Frequently asked questions about Negative Symptoms
What are negative symptoms in AP Psychology?
Negative symptoms are a reduction or absence of normal behaviors, such as diminished emotional expression, low motivation (avolition), reduced speech (alogia), loss of pleasure (anhedonia), and social withdrawal. In the CED they are one of the five symptom areas of schizophrenic spectrum disorders (5.4.B).
Do negative symptoms mean the symptoms are bad and positive symptoms are good?
No. Both types are harmful. "Positive" means something is added to normal experience (like hallucinations), and "negative" means something normal is taken away (like emotional expression or motivation).
What is the difference between positive and negative symptoms of schizophrenia?
Positive symptoms include delusions of persecution or grandeur, hallucinations involving one or more senses, and disorganized thinking or speech. Negative symptoms are deficits like flat affect, avolition, and alogia. Hearing voices is positive, while barely speaking or showing no emotion is negative.
Are negative symptoms the same as depression?
No, though they can look similar. Anhedonia and low motivation appear in both, but depressive disorders (5.4.C) center on a sad, empty, or irritable mood. Negative symptoms of schizophrenia usually occur alongside psychotic features like hallucinations or delusions.
Do antipsychotic medications fix negative symptoms?
Not always. A common exam scenario describes a patient whose hallucinations diminish after six months on an atypical antipsychotic while reduced emotional expression, minimal speech, and lack of motivation persist. The point is that negative symptoms are often harder to treat than positive ones.
