The phonological loop is the component of the working memory model that processes and temporarily stores verbal and acoustic information, like silently repeating a phone number to yourself until you can dial it.
The phonological loop is one piece of the working memory model, the framework that treats short-term memory as an active workspace instead of a single holding bin. Its job is sound. It briefly stores verbal and acoustic information (words, numbers, anything you can say or hear) and keeps that information alive through rehearsal. When you repeat a locker combination under your breath while walking down the hall, that's your phonological loop running.
Think of it as an inner voice plus an inner ear on a short tape loop. The information fades fast unless you keep replaying it. In the working memory model, the phonological loop works alongside the visuospatial sketchpad (which handles images and locations) and is coordinated by the central executive, the manager that decides where your attention goes. Because the loop and the sketchpad are separate systems, you can rehearse a phone number and picture a map at the same time, but trying to do two verbal tasks at once jams the same channel.
The phonological loop lives in Unit 2 (Cognition), Topic 2.3 (Introduction to Memory), and supports learning objective AP Psych Revised 2.3.A, which asks you to explain how the types, structures, and processes of memory work. The working memory model is one of the major structural accounts of memory in the CED, sitting alongside the multi-store model and the levels of processing model. Knowing the phonological loop means you can do more than name a memory store. You can explain why certain task combinations interfere with each other and others don't, which is exactly the kind of applied reasoning AP Psych questions reward.

Visuospatial Sketchpad (Unit 2)
The sketchpad is the loop's visual twin. It holds images and spatial layouts while the loop holds sounds and words. Exam scenarios love pairing them, like a student picturing where her textbook sits while rehearsing a phone number, because each task uses a different system and they don't interfere.
Multi-Store Model (Unit 2)
The multi-store model treats short-term memory as one simple stop between sensory memory and long-term memory. The working memory model breaks that single stop into specialized parts, and the phonological loop is one of them. Knowing this lets you explain what working memory adds that the multi-store model misses.
Levels of Processing Model (Unit 2)
Repeating a number in your phonological loop is shallow, maintenance rehearsal. The levels of processing model explains why that keeps info around for seconds but rarely creates a lasting memory, while deeper, meaning-based processing does. The two models answer different questions, holding versus encoding.
This term shows up almost entirely in scenario-based multiple-choice questions. A typical stem describes someone doing two tasks at once, like remembering a number string while arranging shapes, and asks which working memory component handles each task or why performance breaks down. The move you need to make is matching the type of information to the component. Verbal or acoustic info (numbers, letters, spoken words) goes to the phonological loop, visual and spatial info goes to the sketchpad, and coordinating both falls to the central executive. Watch for stems that report memory span data, where recall is better for numbers and letters than for shapes; that pattern points to verbal rehearsal in the phonological loop. No released FRQ has used this term verbatim, but it fits the Article Analysis Question well, since dual-task memory experiments are classic research designs.
Both are temporary storage components of working memory, so it's easy to blur them. The split is by information type, not difficulty. The phonological loop handles anything verbal or sound-based, even if you read it (you convert text to inner speech). The visuospatial sketchpad handles images, shapes, and locations. Quick test: if the person in the question is silently repeating something, it's the loop; if they're picturing or mentally placing something, it's the sketchpad.
The phonological loop is the part of working memory that temporarily holds verbal and acoustic information, like a phone number you're rehearsing.
It works like an inner voice plus inner ear, and information fades within seconds unless you keep rehearsing it.
The phonological loop handles sounds and words, while the visuospatial sketchpad handles images and locations, so the two can run at the same time without interfering.
Two verbal tasks at once overload the loop, which is why you can't rehearse a number while listening closely to a lecture.
Exam questions test this term through dual-task scenarios, so always match the type of information in the stem (verbal vs. visual) to the right working memory component.
It's the component of the working memory model that processes and temporarily stores verbal and acoustic information. Rehearsing a phone number in your head is the textbook example, and it falls under Topic 2.3 (Introduction to Memory) in Unit 2.
They store different kinds of information. The phonological loop holds verbal and sound-based info (numbers, words, spoken language), while the visuospatial sketchpad holds visual and spatial info (images, shapes, locations). They're separate systems, which is why you can do one verbal and one visual task at the same time.
No. The phonological loop is one specialized component inside the working memory model, which replaced the idea of short-term memory as a single store. Working memory also includes the visuospatial sketchpad and the central executive that coordinates them.
Numbers and letters can be rehearsed verbally in the phonological loop, which is very efficient at keeping that info alive. Abstract shapes are hard to name, so they rely on the visuospatial sketchpad without the boost of verbal rehearsal, and recall drops.
No, it only holds information for a few seconds while you rehearse it. Getting information into long-term memory requires encoding processes like deep, meaning-based processing, which is what the levels of processing model describes.
