Class 11 Psychology - KERALA
Human Memory
The Human Memory chapter in Kerala SCERT Class 11 Psychology explores how our minds encode, store, and retrieve information. It delves into the Atkinson-Shiffrin Information Processing Model, covering sensory memory, short-term memory, and long-term memory. Students also learn about the nature of forgetting, prominent theories like the interference and trace decay theories, and practical methods to enhance memory through mnemonics. Understanding these cognitive processes is vital for board exams as it tests both theoretical concepts and practical applications related to human learning and behavior.

Information Processing Model
A model proposed by Atkinson and Shiffrin suggesting that memory processing involves three distinct stages: Sensory Memory, Short-Term Memory (STM), and Long-Term Memory (LTM).
Sensory Memory
The initial memory stage that holds environmental information through our senses for a very brief duration, typically lasting less than a second.
Short-Term Memory (STM)
A memory system that holds a limited amount of information for a brief period, usually around 30 seconds, unless rehearsal is used.
Long-Term Memory (LTM)
The permanent or semi-permanent storage system of the brain with a seemingly unlimited capacity to hold facts, events, and skills over long periods.
Levels of Processing
A theory by Craik and Lockhart stating that the depth at which we analyze information during encoding (structural, phonemic, or semantic) determines how well we remember it.
Forgetting (Ebbinghaus Forgetting Curve)
The inability to retrieve previously stored information, which Hermann Ebbinghaus showed happens rapidly soon after learning and then levels off over time.

Board Exam Info
In the Kerala SCERT Class 11 Psychology examinations, the Human Memory chapter typically carries around 6 to 9 marks. Questions frequently include short answers defining memory stages, essay questions on the Atkinson-Shiffrin model or causes of forgetting, and objective-type or application-based questions regarding mnemonic techniques.
Frequently Asked Questions
What is the difference between short-term memory and long-term memory?
Short-term memory has a limited capacity (about 7 items) and duration (up to 30 seconds), whereas long-term memory has a vast, unlimited capacity and can store information for a lifetime.
Why do we forget things according to psychology?
We forget due to various reasons such as trace decay (fading over time), interference (new or old memories blocking retrieval), lack of proper encoding, or retrieval failure.
What are mnemonics and how do they help?
Mnemonics are memory aids or strategies—like chunking, acronyms, or visual imagery—that help organize information and make it easier to encode and retrieve during exams.
