Sabrina had been studying all night for her Psychology exam. When she finally sat down to take it, her mind went blank. She was so frustrated! All night she had repeated the definitions of terms over and over again, using flash cards and her notes to quiz herself on the material. She even memorized an acronym for one of the concepts, called OCEAN. She remembered how in class her professor had taught her this little trick using a picture of the word next to a whale in a party hat, and she thought the picture was adorable. Unfortunately, she was too distracted thinking about all of the errands she had to run after class and never caught what the first letter of the acronym stood for. She remembered there were 5 letters: C was for Conscientiousness, E for Extroversion, A for Agreeableness, and N for Neuroticism. Sabrina looked out her window in frustration, noticing that the store across the street had a neon OPEN sign. “That’s it!” she thought excitedly, “O is for Openness!” Sabrina would get this question right on the test for sure.

🧠 In-Depth Explanation
Sabrina’s experience illustrates several foundational concepts in cognitive psychology related to memory and learning. Let’s go through each question step-by-step, explaining both the correct answers and the theories behind them.
Question 1: Sabrina was experiencing ____ when she couldn’t remember the first letter of the acronym, but could remember the others.
Correct Answer: Interference
Sabrina’s inability to recall the first letter of the acronym “OCEAN” despite recalling the rest is best explained by interference. Interference occurs when information that is similar in format gets in the way of recalling specific pieces of data. There are two main types:
- Proactive Interference: Older memories interfere with the retrieval of new ones.
- Retroactive Interference: Newer information interferes with recalling older memories.
In Sabrina’s case, all the flashcards and repeated exposure to different traits and terms likely caused similar information to compete, preventing her from easily retrieving “Openness.”
- Decay would imply the information simply faded over time, which is unlikely since she just studied it the night before.
- Context-dependent memory refers to retrieving information better when in the same environment where it was encoded—not applicable here.
- None of these would be incorrect as “Interference” is the best fit.
Question 2: The facts and pieces of information that Sabrina memorized all night were stored as semantic memories.
Correct Answer: True
Semantic memory refers to general world knowledge that we accumulate throughout our lives. This includes facts, concepts, and meanings—like knowing the Big Five personality traits.
In contrast:
- Episodic memory is tied to personal experiences (e.g., remembering a specific study session).
- Procedural memory is related to motor skills and habits (e.g., how to ride a bike).
Since Sabrina memorized definitions and psychological terms, this is clearly semantic memory.
Question 3: Sabrina’s use of the OCEAN acronym is an example of…
Correct Answer: Chunking
Chunking is a memory strategy that involves grouping individual pieces of information into larger, more meaningful units. Acronyms are a classic example. Instead of remembering five separate personality traits, Sabrina memorized one word (“OCEAN”) as a mnemonic device.
Let’s briefly contrast this with the other options:
- Iconic memory is a form of sensory memory related to visual stimuli—this only lasts a fraction of a second.
- Immediate memory span refers to the number of items (usually 7 ± 2) that can be held in short-term memory.
- Flashbulb memory involves vivid, emotional recollections of a significant event (e.g., remembering where you were on 9/11).
Thus, chunking is the most accurate choice here.
Question 4: The process of Sabrina listening to her Instructor’s lecture is encoding.
Correct Answer: True
Encoding is the first stage of memory processing. It involves converting sensory input (like sounds or visuals) into a form the brain can store and retrieve later.
There are different levels of encoding:
- Structural (shallow) – focusing on how something looks
- Phonemic – focusing on how something sounds
- Semantic (deep) – focusing on meaning
When Sabrina listened to the lecture, her brain was encoding the verbal input into memory—particularly through semantic encoding, since she was processing the meaning of psychological terms.
Question 5: In order for Sabrina to chunk efficiently, she would need to…
Correct Answer: All of the above
Let’s break down the requirements for efficient chunking:
- Use her long-term memory: Chunking depends on drawing from knowledge already stored in long-term memory to make sense of and group new information. For example, we can remember a phone number more easily if we group digits in a familiar pattern.
- Group all items into one chunk: The power of chunking comes from combining smaller units into meaningful wholes. “OCEAN” becomes a single meaningful unit representing five traits.
- Transfer information from short-term to long-term memory: Chunking not only helps retain information in working memory, but also facilitates its encoding into long-term memory.
Therefore, to chunk efficiently, all of these components are necessary.
Question 6: The information that Sabrina learned and recalled from the lecture was stored in long-term memory.
Correct Answer: True
Long-term memory (LTM) has a vast capacity and can store information for a potentially unlimited duration. Since Sabrina was able to recall the meanings of “C,” “E,” “A,” and “N” (and eventually “O”), this information must have been encoded, consolidated, and retrieved from LTM.
Even though she temporarily forgot the first item, the fact that it came back to her when she saw the “OPEN” sign confirms that the memory was still stored, just inaccessible temporarily—another reason why interference is such a key concept in her experience.
🧩 Memory and Learning: The Bigger Picture
Sabrina’s situation demonstrates how human memory is dynamic, reconstructive, and highly influenced by attention, emotion, and context.
Key Takeaways:
- Effective encoding strategies like chunking and mnemonic devices (like OCEAN) aid in memory retention.
- Interference is a common cause of retrieval failure, especially when learning similar material.
- Semantic memory is used for storing factual and conceptual knowledge.
- The encoding-storage-retrieval model of memory helps explain how we process and recall information.
- Long-term memory storage is not flawless—it’s prone to temporary blocks, distractions, and mixing up of similar concepts.
Studying more effectively involves:
- Deep processing (engaging with meaning rather than rote memorization)
- Spaced repetition instead of cramming
- Minimizing interference by taking breaks and reviewing consistently
- Applying contextual cues and visual imagery (e.g., the whale with a party hat) to enhance recall
