Memory systems are multifaceted, comprising shortterm, long-term, and working memory from "summary" of Cognitive Neuroscience by Gazzaniga,Michael,Ivry,Richard B.,Mangun,George R.
Memory encompasses several distinct systems, each serving unique functions. Short-term memory, often referred to as "working memory," allows individuals to hold a limited amount of information temporarily for immediate tasks. This system is crucial for daily activities, such as remembering a phone number long enough to dial it or keeping track of a list while shopping. Its capacity is limited, often cited as seven plus or minus two items, highlighting the challenges of processing information in a fast-paced environment. In contrast, long-term memory is responsible for storing information over extended periods. This system is not limited by capacity, allowing for the retention of vast amounts of knowledge and experiences. Long-term memory can be further categorized into explicit (or declarative) memory, which encompasses facts and events, and implicit (or non-declarative) memory, which involves skills and conditioned responses. The processes of encoding, storage, and retrieval are vital for transferring information from short-term to long-term memory. Working memory acts as a mental workspace, integrating information from both short-term and long-term systems. It allows for manipulation and organization of information, enabling problem-solving and decision-making. This system is dynamic, constantly updating based on new input and prior knowledge. The interaction among these memory systems is essential for cognitive functions, influencing learning, comprehension, and adaptation to new situations. The interplay highlights the complexity of memory as not merely a repository of information but a vital component of intelligent behavior and emotional experience, demonstrating the brain's remarkable capacity to navigate and make sense of the world.
