Module 1: Introduction to Memory
Introduction to Memory
Knowledge check
Q1. Which of the following best describes the three core processes of memory?
- A. Sensing, thinking, and feeling
- B. Encoding, storage, and retrieval ✓
- C. Attention, perception, and recall
- D. Input, processing, and output
Why: Memory is commonly described as involving encoding (converting information into a usable form), storage (maintaining that information over time), and retrieval (accessing it when needed). Each stage can fail independently, which explains many forgetting experiences.
Q2. What is the term for the very brief sensory memory that holds visual information for less than a second?
- A. Working memory
- B. Long-term memory
- C. Iconic memory ✓
- D. Procedural memory
Why: Iconic memory is the visual sensory store, first described by George Sperling, that holds a fleeting image of what is seen for roughly a quarter to half a second. Working memory and long-term memory are later stages, and procedural memory is a type of long-term memory.
Q3. Which model proposed that memory consists of sensory memory, short-term store, and long-term store?
- A. Levels of processing model
- B. Working memory model
- C. Multi-store (Atkinson-Shiffrin) model ✓
- D. Connectionist model
Why: The Atkinson-Shiffrin multi-store model (1968) describes memory as a sequence of stores through which information passes. The levels of processing model instead emphasizes depth of processing, and the working memory model refines the short-term component rather than describing the full three-store sequence.
Q4. Which term refers to the ability to consciously recall facts and events?
- A. Implicit memory
- B. Explicit memory ✓
- C. Procedural memory
- D. Priming
Why: Explicit (declarative) memory involves conscious recollection of facts and personal experiences, such as remembering the capital of France or your last birthday. Implicit memory, by contrast, influences behavior without conscious awareness, as in riding a bicycle or priming effects.
Q5. According to the levels of processing framework proposed by Craik and Lockhart, what most strongly improves memory retention?
- A. Repeating information aloud without thinking about it
- B. Processing information deeply, such as by focusing on its meaning ✓
- C. Reading information quickly several times
- D. Writing information down without reflecting on it
Why: Craik and Lockhart (1972) argued that deeper, semantic processing, which focuses on meaning, produces more durable memories than shallow processing based on physical or surface features. Rote repetition, known as maintenance rehearsal, provides less lasting retention than elaborative processing.

Module 2: Encoding: Getting Information In
Encoding: Getting Information In
Knowledge check
Q1. Which term describes the process of converting sensory input into a form that can be stored in memory?
- A. Retrieval
- B. Encoding ✓
- C. Consolidation
- D. Decay
Why: Encoding is the first stage of memory, where incoming information is transformed into a representation the brain can store. Retrieval is getting information back out, consolidation is stabilizing stored memories over time, and decay is the gradual loss of memory traces.
Q2. Which type of encoding involves processing the meaning of information rather than its sound or appearance?
- A. Visual encoding
- B. Acoustic encoding
- C. Semantic encoding ✓
- D. Phonemic encoding
Why: Semantic encoding focuses on the meaning of words or ideas. Research by Craik and Lockhart showed that deeper, meaning-based processing leads to much better memory than shallow processing based on physical features such as how a word looks or sounds.
Q3. What is the name of the effect where people remember items at the beginning and end of a list better than items in the middle?
- A. Primacy and recency effect ✓
- B. Spacing effect
- C. Testing effect
- D. Context-dependent effect
Why: The serial position effect combines the primacy effect (better memory for early items, which get more rehearsal and transfer to long-term memory) and the recency effect (better memory for the last items, which are still held in short-term memory).
Q4. Which encoding strategy involves linking new information to things you already know?
- A. Rote repetition
- B. Elaboration ✓
- C. Shallow scanning
- D. Passive re-reading
Why: Elaboration means adding meaning by connecting new material to existing knowledge, examples, or personal experiences. This creates more retrieval pathways, which makes encoding stronger than simply repeating the information without connecting it to anything.
Q5. Mental imagery tends to improve memory encoding because it:
- A. Replaces the need for verbal information entirely
- B. Creates a dual code, combining visual and verbal representations ✓
- C. Prevents forgetting by blocking interference
- D. Shortens the time information stays in sensory memory
Why: Paivio's dual-coding theory proposes that information encoded both verbally and visually has two retrieval routes, making it easier to remember. Imagery adds a visual code alongside the verbal one, which is why vivid mental pictures often help recall.
Module 3
Module 3: Storage: How Memories Are Held
Storage: How Memories Are Held
Knowledge check
Q1. Which term describes the process of keeping information over time so it can be retrieved later?
- A. Encoding
- B. Storage ✓
- C. Retrieval
- D. Attention
Why: Storage is the stage of memory that maintains encoded information over time. Encoding gets information in, and retrieval brings it back out, so storage is the middle step that holds it.
Q2. Which type of memory holds information for only about 15 to 30 seconds without rehearsal?
- A. Long-term memory
- B. Procedural memory
- C. Short-term memory ✓
- D. Semantic memory
Why: Short-term memory has a limited capacity and a brief duration, lasting roughly 15 to 30 seconds unless the information is rehearsed. Long-term memory can persist for years or a lifetime.
Q3. What is the process of repeating information to keep it in memory longer?
- A. Consolidation
- B. Rehearsal ✓
- C. Decay
- D. Chunking
Why: Rehearsal means repeating information, either silently or aloud, to keep it active in short-term memory and to help transfer it toward long-term storage. Chunking is a separate strategy that groups items together to increase capacity.
Q4. What is the term for the process that stabilizes new memories over time so they become durable in long-term storage?
- A. Consolidation ✓
- B. Recall
- C. Priming
- D. Recognition
Why: Consolidation is the process by which newly formed memory traces are stabilized and strengthened, often during sleep, so they can be stored long-term. Recall and recognition are retrieval processes, not storage processes.
Q5. Which brain structure is most closely associated with consolidating new declarative memories into long-term storage?
- A. The cerebellum
- B. The hippocampus ✓
- C. The medulla
- D. The occipital lobe
Why: The hippocampus plays a central role in forming and consolidating new declarative memories, the facts and events we can consciously recall. Long-term storage itself is distributed across the cortex over time.
Module 4
Module 4: Retrieval: Getting Information Back Out
Retrieval: Getting Information Back Out
Knowledge check
Q1. Which of the following best describes retrieval in memory?
- A. Storing new information in long-term memory
- B. Accessing and bringing stored information back into conscious awareness ✓
- C. Paying attention to information as it is presented
- D. Repeating information to keep it active in short-term memory
Why: Retrieval refers to the process of getting stored information back out of memory so it can be used, which is distinct from encoding (storing) and attention (focusing).
Q2. What is the term for recalling information from memory without any cues or hints?
- A. Recognition
- B. Relearning
- C. Free recall ✓
- D. Cued recall
Why: Free recall requires retrieving information with no prompts, such as listing as many words from a list as you can remember. Recognition and cued recall both provide some form of cue.
Q3. Which retrieval task is typically easier: recognition or free recall?
- A. Free recall, because it draws on more retrieval cues
- B. Recognition, because the correct answer is presented and only needs to be identified ✓
- C. Both are equally difficult
- D. Neither, because both require the same amount of effort
Why: Recognition involves identifying a previously seen item among options, which provides external cues. Free recall requires generating the information entirely from memory, making it more demanding.
Q4. What does the term 'retrieval cue' refer to?
- A. A memory that has been permanently lost
- B. A stimulus or hint that helps trigger the recall of a stored memory ✓
- C. The initial moment when information is first learned
- D. A strategy for organizing notes before an exam
Why: A retrieval cue is any stimulus, word, smell, or context that helps activate and access a specific memory. Effective cues are connected to the information when it was originally encoded.
Q5. Why does studying in the same room where you will be tested often improve performance?
- A. The room is quieter, which reduces distraction
- B. The environmental context serves as a retrieval cue that matches the original learning context ✓
- C. Familiar rooms increase general alertness
- D. Testing rooms are always designed to match study conditions
Why: This is the context-dependent memory effect. When the surroundings at retrieval match those present during encoding, the contextual cues help bring the stored information back to mind.

Module 6: Forgetting and Why It Happens
Forgetting and Why It Happens
Knowledge check
Q1. According to the forgetting curve first described by Hermann Ebbinghaus, what typically happens to newly learned information over time?
- A. It is retained at full strength indefinitely once learned
- B. It declines rapidly at first and then more slowly over time ✓
- C. It increases in strength during the first week after learning
- D. It disappears all at once after exactly 24 hours
Why: Ebbinghaus found that forgetting is steepest soon after learning and levels off gradually, so the largest loss happens early on.
Q2. Which term describes forgetting that happens because a memory cue is missing, so the stored information cannot be accessed?
- A. Decay
- B. Interference
- C. Retrieval failure ✓
- D. Consolidation
Why: Retrieval failure means the memory is still stored but cannot be reached without the right cue, such as forgetting a name until you see a familiar face.
Q3. When newer memories disrupt the recall of older, similar memories, what is this called?
- A. Proactive interference
- B. Retroactive interference ✓
- C. Encoding specificity
- D. Priming
Why: Retroactive interference occurs when new learning backward-disrupts older memories, such as a new phone number making you forget an old one.
Q4. Which of the following is a strategy that helps reduce forgetting over time?
- A. Cramming all material the night before a test
- B. Spaced repetition, reviewing material at increasing intervals ✓
- C. Rereading notes repeatedly in a single sitting
- D. Avoiding any review after the first study session
Why: Spaced repetition takes advantage of the spacing effect, strengthening memory by reviewing information at intervals that counter the forgetting curve.
Q5. What is the term for the idea that forgetting is caused by the gradual fading of memory traces when they are not used?
- A. Repression
- B. Decay theory ✓
- C. Source amnesia
- D. Motivated forgetting
Why: Decay theory proposes that memory traces weaken over time when unused, although it is debated whether passive decay alone explains most forgetting.

Improving Memory in Everyday Life
Knowledge check
Q1. Which strategy involves linking new information to something you already know in order to make it easier to remember?
- A. Rote repetition
- B. Association ✓
- C. Skimming
- D. Cramming
Why: Association connects new information to existing knowledge or vivid images, creating more retrieval pathways in memory, which makes recall easier than simply repeating information over and over.
Q2. What is the main benefit of spacing out study sessions over time rather than studying everything in one long session?
- A. It reduces the total amount of material you need to learn
- B. It takes advantage of the spacing effect, which strengthens long-term retention ✓
- C. It prevents you from ever forgetting anything
- D. It makes sleep unnecessary for memory consolidation
Why: The spacing effect shows that memories are stronger when learning is distributed across multiple sessions, because each review occurs just as the memory begins to fade, which strengthens the memory trace.
Q3. Which of the following is an example of retrieval practice?
- A. Rereading your notes several times
- B. Highlighting key sentences in a textbook
- C. Closing your book and writing down everything you can remember about the topic ✓
- D. Listening to a lecture recording at double speed
Why: Retrieval practice means actively pulling information out of memory, such as through self-quizzing or free recall. This effort strengthens memory more than passive review methods like rereading or highlighting.
Q4. How does getting adequate sleep help improve memory?
- A. Sleep prevents new memories from forming at all
- B. Sleep helps consolidate memories, transferring information from short-term to long-term storage ✓
- C. Sleep erases all memories from the previous day
- D. Sleep only affects physical memory, not thinking or learning
Why: During sleep, especially deep sleep and REM sleep, the brain replays and stabilizes newly learned information, helping move it into long-term memory storage.
Q5. Which everyday habit is most likely to help you remember where you placed your keys or glasses?
- A. Placing them in the same designated spot every time ✓
- B. Setting them down wherever is convenient
- C. Thinking about something else while putting them down
- D. Asking someone else to remember for you every time
Why: Consistent routines reduce the mental load of encoding and retrieval, because the habit itself becomes a reliable cue. Random placement, distraction, and relying on others all make the location harder to recall later.
