Explicit Memory in AP Psychology

In AP Psychology, explicit (declarative) memory is long-term memory you consciously retrieve and can easily describe to others. It comes in two types: semantic memory for facts and knowledge, and episodic memory for personal experiences and events.

What is Explicit Memory?

Explicit memory (also called declarative memory) is the kind of long-term memory you can consciously pull up and declare. If you can explain it to someone else, it's probably explicit. The CED describes it as memory that is "more easily described or explained to others."

The CED splits explicit memory into two types:

• Semantic memory holds facts and general knowledge. Knowing that Paris is the capital of France, or knowing the steps of a recipe as a list of ingredients, is semantic.
• Episodic memory holds your personal experiences, tied to a specific time and place. Remembering your trip to Paris, or where you parked this morning, is episodic.

A quick way to keep them straight is that semantic memory is "knowing that" and episodic memory is "remembering when." Both count as explicit because you're aware you're retrieving them and you can talk about them. That awareness is exactly what separates explicit memory from implicit memory.

Why Explicit Memory matters in AP® Psychology

Explicit memory lives in Unit 2: Cognition, under Topic 2.3 Introduction to Memory. It directly supports learning objective AP Psych 2.3.A: "Explain how the types, structures, and processes of memory work." The essential knowledge for that objective says memories for knowledge, events, and experiences differ in how the brain processes, stores, and retrieves them. Explicit memory (episodic and semantic) is then set against implicit memory (procedural) and prospective memory.

This is a sorting skill. The exam hands you a scenario and asks what type of memory it shows. Explicit memory is the anchor category for that whole classification system, so if you understand it, the other memory types click into place around it. For the full picture of memory structures and processes, see the Topic 2.3 study guide.

How Explicit Memory connects across the course

Implicit Memory (Unit 2)

Implicit memory is explicit memory's opposite. Explicit memories are ones you can describe, while implicit memories, like procedural memory for riding a bike, show up in what you do rather than what you can say. One useful contrast is that implicit procedural memories tend to be more resistant to forgetting than explicit memories of facts and events.

Long-Term Memory and the Multi-Store Model (Unit 2)

Explicit memory is a branch of long-term memory, the final stop in the multi-store model after sensory memory and short-term memory. Think of long-term memory as the filing cabinet and explicit memory as the drawers you can open on purpose and read aloud from.

Recall and Recognition (Unit 2)

Recall and recognition are the two main ways you retrieve explicit memories. Recall pulls a fact out with few cues, as on a fill-in-the-blank question. Recognition picks it out from options, as on a multiple-choice question. Both are tests of conscious, declarative retrieval.

Long-Term Potentiation (Unit 2)

Long-term potentiation is the biology underneath memory, the process by which synaptic connections between neurons get stronger. It links the psychological idea of storing an explicit memory to the neural changes that make that storage possible.

Is Explicit Memory on the AP® Psychology exam?

Explicit memory shows up mostly in scenario-based multiple-choice questions that ask you to classify a memory. Expect stems like these:

• Episodic vs. semantic within explicit memory. A chef easily recalls ingredients for dozens of recipes (semantic) but forgets where he parked this morning (episodic). The question asks which types of explicit memory the difference illustrates.
• Research-design framing. An experiment contrasts "knowing that Paris is the capital of France" with "remembering their trip to Paris." That's semantic vs. episodic.
• Explicit vs. implicit. A question asks why implicit procedural memories resist forgetting better than explicit memories of facts and events.

Your job is to spot the cue words. "Knows that" or general facts point to semantic memory. A specific personal event with a time and place points to episodic memory. A skill done automatically points to implicit or procedural memory. No released FRQ has used "explicit memory" verbatim. It still fits naturally into FRQ prompts that ask you to apply memory concepts to a scenario, so be ready to name the type and explain why the example fits.

Explicit Memory vs Implicit Memory

Explicit memory is conscious and easy to put into words, like facts (semantic) and personal events (episodic). Implicit memory works without conscious recollection and is hard to explain, like procedural memory for tying your shoes or typing. To test which one you're dealing with, ask whether the person could tell you the memory or could only show you. Telling means explicit. Showing means implicit.

Key things to remember about Explicit Memory

• Explicit memory, also called declarative memory, is long-term memory you consciously retrieve and can easily describe to others.

• The two types of explicit memory are semantic memory, which stores facts and general knowledge, and episodic memory, which stores personal experiences tied to a time and place.

• Knowing that Paris is the capital of France is semantic memory, while remembering your own trip to Paris is episodic memory.

• Implicit memory, including procedural memory for skills, is the contrast category because it is hard to put into words and shows up in performance instead.

• Implicit procedural memories tend to be more resistant to forgetting than explicit memories of facts and events.

• Explicit memory is tested under learning objective AP Psych 2.3.A in Topic 2.3, usually through scenarios that ask you to classify a memory type.

Frequently asked questions about Explicit Memory

What is explicit memory in AP Psychology?

Explicit memory is conscious, declarative long-term memory that you can easily describe to others. It includes semantic memory (facts and knowledge) and episodic memory (personal experiences), and it's covered in Topic 2.3 under learning objective AP Psych 2.3.A.

What's the difference between explicit and implicit memory?

Explicit memory is conscious and easy to explain, like knowing a historical date or remembering your last birthday. Implicit memory is hard to put into words and shows up in behavior, like the procedural memory that lets you ride a bike without thinking about it.

Is procedural memory a type of explicit memory?

No. Procedural memory is a type of implicit memory because it covers skills and processes you perform automatically and can't easily describe. Only episodic and semantic memory fall under explicit memory in the CED.

How do I tell episodic memory from semantic memory on the AP exam?

Ask whether the memory is a general fact or a personal event. A chef remembering recipe ingredients is using semantic memory. That same chef remembering where he parked this morning is using episodic memory, because it's tied to a specific time and place in his life.

Is explicit memory the same as declarative memory?

Yes. Explicit memory and declarative memory are two names for the same thing, memory you can consciously "declare" or put into words. Either term can appear on the exam, so treat them as interchangeable.
