Introduction

Understanding how human memory functions is fundamental in cognitive psychology, as it elucidates the processes behind how we encode, store, and retrieve information. Memory is typically conceptualized as a series of stages—sensory memory, short-term memory, and long-term memory—each with distinct characteristics and functions. This paper explores these stages utilizing the memory diagram and course notes, delves into various memory types, mechanisms facilitating memory retention and retrieval, and discusses factors influencing memory efficacy, such as interference, cues, and rehearsal strategies. Additionally, the paper considers personal attributes related to intelligence and creativity.

1. Why do we call the first/entry stage of memory "sensory memory"?

The initial stage of memory is called "sensory memory" because it serves as the first entry point for sensory information received from the environment. Sensory memory briefly holds incoming sensory stimuli—visual, auditory, tactile—for a very short duration, typically milliseconds to a few seconds. It functions as a buffer, allowing the brain to momentarily retain sensory impressions, providing the opportunity for selective attention to determine which stimuli are processed further (Sperling, 1960). This stage is essential because it preserves an accurate representation of sensory input momentarily, ensuring that meaningful information can be transferred to subsequent memory stages.

2. What do we have to do to move sensory memories to short-term memory?

To transfer sensory memories to short-term memory, we must focus our attention on the relevant sensory input. This process involves selective attention, where cognitive resources are directed toward specific stimuli while ignoring others. When attention is allocated to particular sensory information, it is encoded into short-term memory, where it can be actively processed and maintained for a limited duration (Atkinson & Shiffrin, 1968). Without attention, sensory information quickly fades and is lost.

3. What is short-term memory? What else do we call short-term memory?

Short-term memory (STM) is a temporary storage system that holds a limited amount of information for a brief period, generally around 15-30 seconds, without active rehearsal. It allows immediate consciousness and manipulation of information, playing a critical role in everyday cognitive tasks such as reasoning and decision-making. Short-term memory is also commonly referred to as "working memory" because it supports ongoing mental activities and the manipulation of information (Baddeley & Hitch, 1974).

4. What is long-term memory? How do we store and retrieve information?

Long-term memory (LTM) is a more permanent storage system capable of holding vast amounts of information over extended periods, from hours to a lifetime. It involves processes such as encoding, consolidation, storage, and retrieval. Encoding converts sensory or short-term information into a durable form suitable for long-term storage, often through elaborative rehearsal, association, or semantic processing. Retrieval involves accessing stored information, often facilitated by cues or context, to bring it back into conscious awareness (Craik & Tulving, 1975). The neural basis of these processes involves complex interactions across various brain regions, predominantly the hippocampus and related cortical areas.

5. How long does information stay in long-term memory? How much information can long-term memory hold?

Information in long-term memory can last from hours to a lifetime, with retention depending on various factors such as rehearsal, significance, and retrieval cues (Rubin, 1981). The capacity of long-term memory is effectively limitless; it can store an enormous amount of information, including facts, skills, experiences, and personal memories, without a definitive storage limit. The challenge often lies in retrieving stored information rather than storing it.

6. What is elaborative rehearsal? Why would it make something easier to remember?

Elaborative rehearsal involves actively associating new information with existing knowledge, creating meaningful connections that enhance encoding depth. Unlike rote repetition, elaborative rehearsal incorporates semantic processing, making the information more distinctive and easier to retrieve later (Craik & Tulving, 1975). For example, relating a new concept to personal experiences or related knowledge creates stronger neural ties, improving long-term retention.

7. What is episodic memory? Give a specific example.

Episodic memory pertains to the recollection of specific personal experiences situated in particular contexts, including time and place. It allows individuals to mentally "travel" back to events from their lives. For instance, remembering your first day at university—what you saw, heard, and felt—is an example of episodic memory (Tulving, 1972).

8. What is procedural memory? Give an example.

Procedural memory involves the unconscious recall of how to perform tasks or skills without conscious awareness of the learning process. These are often motor or habitual actions. An example is riding a bicycle—once learned, it can be performed automatically without conscious effort (Squire, 1992).

9. What is semantic memory? Give an example.

Semantic memory stores general knowledge about the world, facts, concepts, and vocabulary independent of personal experience. For example, knowing that Paris is the capital of France or that water boils at 100°C are examples of semantic memory.

10. What is a sensory cue? Explain how sensory cues help memory retrieval.

A sensory cue is a stimulus—visual, auditory, olfactory, tactile, or gustatory—that triggers the retrieval of specific memories. Sensory cues are particularly effective because they tap into the neural pathways associated with the original encoding of the memory, facilitating access. For example, the smell of baked bread may remind someone of childhood visits to a bakery (Godden & Baddeley, 1975).

11. What are flashbulb memories?

Flashbulb memories are vivid, detailed recollections of emotionally significant or shocking events. They are characterized by high confidence and clarity, often associated with major historical or personal events, such as a national crisis or personal tragedy. Despite their vividness, research indicates that flashbulb memories can still be susceptible to distortion over time (Brown & Kulik, 1977).

12. Why do we use the word "constructed" for memories?

The term "constructed" emphasizes that memories are active reconstructions rather than exact replicas of past events. Each time we recall a memory, it can be influenced by current beliefs, knowledge, and feelings, leading to modifications. This reconstructive nature explains why memories can be inaccurate or altered over time (Loftus, 1997).

13. How does the curve of forgetting warn us?

The curve of forgetting, proposed by Ebbinghaus, demonstrates that memory retention declines rapidly within the first days after learning and stabilizes over time. This warns us of the importance of review and reinforcement to prevent forgetting. Regular rehearsal and retrieval practice are crucial to consolidating memories and maintaining long-term retention (Ebbinghaus, 1885).

14. How can interference interfere with memory retrieval? Provide a real-life example.

Interference occurs when similar information competes during retrieval, leading to forgetting. For example, learning two similar languages simultaneously may cause confusion when trying to recall vocabulary, exemplifying retroactive interference, where newly acquired information hampers earlier memories.

15. Explain "positive transfer". Give an example.

Positive transfer occurs when prior learning facilitates the acquisition of new skills or information. An example is a person who learned to drive a manual transmission car finding it easier to learn how to operate a different manual vehicle because of similarities in controls.

16. Explain "negative transfer". Give an example.

Negative transfer happens when previous learning interferes with new learning, causing errors. For instance, a bilingual person might mistakenly apply grammatical rules from their second language to their first language, leading to errors in sentence structure.

17. Describe each of these memory aids with examples: (A) imagery, (B) chunking, (C) clustering.

(A) Imagery involves creating mental pictures to represent information, which enhances memory by engaging visual-spatial processing. An example is visually imagining a grocery list to remember items.

(B) Chunking groups individual items into larger, meaningful units, reducing cognitive load. For example, recalling a 10-digit phone number as three chunks (xxx-xxx-xxxx).

(C) Clustering involves organizing information into categories or related groups, such as grouping vocabulary words by themes during studying.

18. What is rote learning? What is something you learned by rote as a child?

Rote learning involves memorizing information purely through repetition without understanding its meaning. An example is memorizing multiplication tables as a child by repeated practice. While useful for short-term recall, rote learning is less effective for long-term understanding or application of knowledge.

19. Why would we not use rote learning for something we want to retain long-term?

Rote learning tends to result in shallow encoding and does not promote understanding, making retention fragile and easily disrupted. It is less effective for long-term memory because it lacks semantic processing and meaningful connections, which are crucial for durable learning (Craik & Lockhart, 1972).

20. How would you describe an intelligent person? How would you describe a creative person?

An intelligent person is often characterized by their ability to reason, solve problems, and adapt to new situations using acquired knowledge and logical thinking. Creativity involves the capacity to generate novel ideas, approach problems with originality, and think flexibly. Both qualities can intersect but are distinct; intelligence emphasizes logical reasoning, while creativity focuses on innovation and originality.
