Psychology Degree Cognitive Processes and Memory Questions and Answers — Questions and Answers
Question 1: A student finds that they perform better on their final exam when they study in the same classroom where the lectures were held. This phenomenon is best explained by which of the following principles?
- The Levels of Processing Theory
- The Encoding Specificity Principle (Correct answer)
- The Atkinson-Shiffrin Model
- Ebbinghaus's Forgetting Curve
Correct answer: The Encoding Specificity Principle
The Encoding Specificity Principle, proposed by Tulving, states that memory retrieval is most effective when the conditions at the time of retrieval match the conditions at the time of encoding. In this scenario, the classroom environment serves as a contextual cue that was present during encoding (learning) and is now present during retrieval (the exam), thereby enhancing recall.
Question 2: According to the Atkinson-Shiffrin multi-store model of memory, what is the primary mechanism for transferring information from short-term memory to long-term memory?
- Chunking
- Elaborative Rehearsal (Correct answer)
- Sensory Input
- Retrieval
Correct answer: Elaborative Rehearsal
The Atkinson-Shiffrin model posits that information moves from short-term memory (STM) to long-term memory (LTM) through rehearsal. Elaborative rehearsal, which involves thinking about the meaning of the information and connecting it to pre-existing knowledge, is considered more effective for LTM storage than simple maintenance rehearsal (rote repetition).
Question 3: A witness to a crime is having trouble remembering specific details. However, when the detective asks them to describe the weather and how they were feeling that day, the witness begins to recall more information. The detective is leveraging a concept related to:
- State-dependent memory (Correct answer)
- Flashbulb memory
- Procedural memory
- Semantic memory
Correct answer: State-dependent memory
State-dependent memory is a phenomenon where recall is improved when an individual is in the same internal state (e.g., emotional, physiological) as they were when the memory was formed. By prompting the witness to recall their feelings (internal state) and the weather (external context), the detective is helping to recreate the conditions of the original encoding, which can trigger recall.
Question 4: Which component of Baddeley and Hitch's working memory model is responsible for coordinating the activity of the other slave systems and allocating attentional resources?
- Phonological Loop
- Visuo-Spatial Sketchpad
- Episodic Buffer
- Central Executive (Correct answer)
Correct answer: Central Executive
The Central Executive is the primary component of the working memory model. It functions as a supervisory system that controls and coordinates the other components (the phonological loop, visuo-spatial sketchpad, and episodic buffer). It is responsible for focusing attention, switching between tasks, and interfacing with long-term memory.
Question 5: According to Craik and Lockhart's Levels of Processing theory, which of the following study methods would lead to the most durable memory trace for a list of vocabulary words?
- Repeating the words and their definitions aloud multiple times.
- Noting whether each word is written in uppercase or lowercase letters.
- Generating a unique sentence for each word that uses it in a meaningful context. (Correct answer)
- Counting the number of vowels in each word.
Correct answer: Generating a unique sentence for each word that uses it in a meaningful context.
The Levels of Processing theory suggests that memory retention is a function of the depth of processing. Generating a sentence requires semantic processing (thinking about the word's meaning), which is a deep level of processing. This leads to a more robust and lasting memory compared to shallow processing methods like focusing on physical features (structural processing, e.g., letter case) or sound (phonemic processing, e.g., repetition).
Question 6: A student crams for an exam by studying intensively for eight hours the day before. According to Hermann Ebbinghaus's research on the forgetting curve, what is the most likely outcome?
- The student will retain over 90% of the information for several weeks.
- The rate of forgetting will be slowest in the first 24 hours after studying.
- The student will experience a rapid decline in memory of the material shortly after the exam. (Correct answer)
- The student will form a permanent, flashbulb memory of the material due to the intensity.
Correct answer: The student will experience a rapid decline in memory of the material shortly after the exam.
Ebbinghaus's forgetting curve demonstrates that most forgetting occurs very rapidly after learning, especially when the information is learned in a massed session (cramming). Without spaced repetition or review, the student is likely to forget a significant amount of the information within the first few days, or even hours, following the study session.
A student finds that they perform better on their final exam when they study in the same classroom where the lectures were held.
This phenomenon is best explained by which of the following principles?
