Memory Unveiled: An In-Depth Exploration of the Three Components in Information-Processing Theory

1. Sensory Memory: This is the first component of the memory system, where we initially process and store information collected through our senses, such as sight (iconic memory) or hearing (echoic memory). It has a vast capacity, but its duration is brief, usually about a few seconds or less. They help us perceive the world in a continuous manner rather than in disjointed bits and pieces. 2. Short-term Memory (Working Memory): The short-term memory serves as a temporary storage area where information from sensory memory is retained and processed. It has a limited capacity, usually around 5 to 9 pieces of information at a time. Short-term memory is where we do our "mental work," like problem-solving or decision-making. The information stored here typically lasts from 20 seconds to about a minute. 3. Long-term Memory: Information that has been efficiently processed in short-term memory can be transferred to long-term memory, the storage place for more permanent memories. Long-term memory is thought to have an unlimited capacity and can hold information for a very long period, from minutes to a lifetime. This memory system includes our knowledge about the world, skills, experiences, and personal identity. It comes into play when we want to recall a childhood memory, remember how to ride a bike, or state the capital of a country. These three components differ not only in their capacity (i.e., how much information they can hold), but also in their function (i.e., what they do with that information). Sensory memory captures a wealth of sensory input from the environment, while short-term memory selects, and processes a small part of that information. Long-term memory then archives this information for future recall.
