Korttelirakenne

Korttelirakenne, also known as the short-term memory structure, is a cognitive model that describes how information is processed and stored in the human mind over short periods. It was first proposed by George Miller in 1956, who suggested that the average person can hold about seven (plus or minus two) items of information in their working memory at any given time. This capacity is often referred to as "the magical number seven, plus or minus two."

The model consists of three main components: sensory memory, short-term memory, and long-term memory. Sensory memory is the initial stage where information is briefly held before being processed further. Short-term memory, also known as working memory, is the active system that holds and manipulates information over short periods, typically up to 20-30 seconds. Long-term memory is the repository for information that is stored over extended periods and can be retrieved when needed.

Korttelirakenne is crucial for various cognitive processes, including learning, problem-solving, and decision-making. It plays a significant role in how we process and retain information, and its capacity can be influenced by factors such as attention, practice, and individual differences in cognitive abilities.

The model has been influential in the field of cognitive psychology and has inspired numerous studies and theories aimed at understanding the mechanisms underlying human memory and information processing. Despite its limitations and the emergence of more complex models, Korttelirakenne remains a foundational concept in the study of human cognition.
