Chapter 6: Problem 4
Identify each of the following descriptions as characteristic of sensory memory (SM), short-term memory (STM), or long-term memory (LTM).Duration Potentially permanent _______.
Short Answer
Expert verified
Potentially permanent \(Long-term\) Memory (LTM).
Step by step solution
01
Understand sensory memory characteristics
Sensory Memory (SM) is the very first stage of memory that holds all the information coming from our senses for a very brief period. The duration for sensory memory is usually very short, typically lasting for a few milliseconds to a few seconds.
02
Understand short-term memory characteristics
Short-term Memory (STM) is the second stage of memory where information is temporarily stored and processed before being either transferred to long-term memory or forgotten. The duration of short-term memory varies from a few seconds to around twenty to thirty seconds.
03
Understand long-term memory characteristics
Long-term Memory (LTM) is the third and final stage of memory, where information is stored for extended periods or even permanently. In long-term memory, the capacity and duration of stored memories are thought to be unlimited or potentially permanent.
04
Identify the correct type of memory for the description
Since the given description mentions "potentially permanent," the memory type it is referring to is Long-term Memory (LTM).
So, the correct answer is: Potentially permanent Long-term Memory (LTM).

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Sensory Memory
Imagine every bit of information you encounter—each sound, image, or touch—is a raindrop. Now, envision a surface that catches those raindrops for a mere second before letting them go. This is your sensory memory, a system that processes the flood of information from your senses almost instantaneously.
Information here lasts just a short burst of time, from milliseconds to a few seconds, which is essential for perception continuity and environmental interaction. Without sensory memory, our experiences would be disconnected, as each new sensory signal would seem to appear out of nowhere. This phase acts as a buffer and gives us the ability to decide if the incoming information is worth further processing or can be dismissed as irrelevant.

Short-term Memory
As certain sensory impressions catch our attention, they move from the ephemeral to a slightly more stable stage known as short-term memory (STM). Think of STM as a kind of 'scratch-pad' for temporary recall of the information being processed.
Typically, this memory type holds information for about 20 to 30 seconds. However, without active efforts to maintain it, like repetition or mental manipulation, this information is prone to disappear. Short-term memory is limited not just in duration but also in capacity, generally able to hold about 7±2 items. For students, mastering the art of chunking—grouping information into larger, connected units—can greatly enhance short-term memory retention.

Memory Stages
Understanding memory stages is critical for grasping how our brain handles and retains information. The memory process is usually broken down into three key stages: encoding, storage, and retrieval.
Encoding
At this initial stage, information enters through our senses and is converted into a format that can be processed mentally.Storage
Next, information travels through the stages of sensory, short-term, and potentially to long-term memory, where it can be preserved for future use.Retrieval
Lastly, stored information is accessed and pulled back into conscious thought. Each stage of memory (sensory, short-term, and long-term) serves a distinct function in the process of learning and recalling.Memory Duration
The length of time a memory lasts, termed memory duration, varies dramatically across the different types of memory.
Sensory memories are the sprinters of the memory world—quick and fleeting. Students often never consciously register this memory type. Short-term memory holds onto information just long enough for a little manipulation—like remembering a phone number until you dial it. But for knowledge to stick around longer, like the essence of a Shakespearean play, it must enter long-term memory, an ultra-marathon runner with the potential for seemingly infinite retention. Techniques to enhance the longevity of memory include meaningful learning, repetition, and mnemonic devices.
