Class 11 Psychology - TAMILNADU
Human Memory
The Human Memory chapter in Class 11 Psychology under Tamil Nadu Samacheer Kalvi explores how our mind encodes, stores, and retrieves information. Students will learn about the Atkinson-Shiffrin model featuring sensory memory, short-term memory, and long-term memory. It also covers different types of memory like episodic, semantic, procedural, and declarative, alongside essential memory strategies, levels of processing, and the primary causes of forgetting such as interference and decay. Mastery of this chapter is vital for board exams as it tests both theoretical understanding and real-world psychological applications.
Start Learning FreeKey Concepts
Encoding
The initial process of receiving, organizing, and transforming sensory information into a form that the brain's memory system can accept and store.
Sensory Memory
The initial, brief storage system that holds vast amounts of sensory input for a fraction of a second (iconic memory for visual, echoic for auditory).
Short-Term Memory (STM)
A working memory system that holds a limited amount of information (about 7 items plus or minus 2) for a brief duration of roughly 20 to 30 seconds.
Long-Term Memory (LTM)
The vast and relatively permanent storage system capable of holding unlimited amounts of information over extended periods, ranging from days to a lifetime.
Levels of Processing
Craik and Lockhart's theory proposing that information can be processed at different levels—shallow (structural/phonemic) versus deep (semantic)—affecting how well it is remembered.
Retroactive Interference
A common cause of forgetting where newly learned information disrupts or interferes with the retrieval of older, previously stored memories.

Questions frequently appear as 1-mark objective choices, 2-mark definitions, 3-mark short notes (e.g., types of LTM), and 5-mark essay questions explaining the Atkinson-Shiffrin model or causes of forgetting.
Frequently Asked Questions
What is the difference between short-term memory and long-term memory?
Short-term memory has a very limited capacity and holds information for less than a minute, whereas long-term memory has an unlimited capacity and can store information indefinitely.
Why do we forget things according to psychology?
Forgetting occurs due to trace decay over time, lack of proper encoding, retrieval failure, or interference where old and new memories block each other.
How can I improve my memory for board exams?
You can improve memory by using mnemonic devices, chunking information, engaging in deep semantic processing, and practicing regular spaced repetition.
