Class 11 Psychology - KARNATAKA
Human Memory
The Human Memory chapter in Class 11 Psychology explores how our minds encode, store, and retrieve information. Students will learn about Atkinson and Shiffrin's Stage Model involving Sensory Memory, Short-Term Memory, and Long-Term Memory, as well as Tulving's memory systems. The chapter covers different types of memory like episodic and semantic, and crucial topics such as forgetting, interference, and effective mnemonic strategies to improve retention. This chapter is vital for the Karnataka KSEEB board exams as it features frequently in both conceptual multiple-choice questions and long-answer descriptive sections.

Encoding
The first stage of memory where incoming sensory information is converted into a usable neural format that the brain can recognize and store.
Atkinson and Shiffrin Information Processing Model
A structural model proposing that memory processing passes through three distinct stages: Sensory Memory, Short-Term Memory (STM), and Long-Term Memory (LTM).
Working Memory
A mental workspace proposed by Baddeley that temporarily holds and manipulates information during complex cognitive tasks like reasoning and comprehension.
Levels of Processing
Craik and Lockhart's theory stating that the depth at which we analyze information during encoding (structural, phonemic, or semantic) determines how well it is remembered.
Interference Theory of Forgetting
A theory suggesting that forgetting occurs because memories compete with and disrupt one another; proactive interference involves old memories blocking new ones, while retroactive interference involves new memories blocking old ones.
Mnemonics
Memory enhancement techniques, such as chunking, visualization, or the keyword method, that help organize and retrieve information more efficiently.

Board Exam Info
In the Karnataka (KSEEB) Class 11 Psychology board exams, the Human Memory chapter typically carries around 8 to 12 marks. Students can expect 1-mark multiple choice or fill-in-the-blank questions, 2-mark short answer questions defining key terms like sensory memory or interference, and 5-mark descriptive questions detailing the stage model of memory or causes of forgetting.
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 (less than 30 seconds), whereas long-term memory has a virtually unlimited capacity and can store information for a lifetime.
Why do we forget things according to psychology?
Forgetting can happen due to trace decay over time, interference from other memories, failure to properly encode information, or retrieval failure where the memory is present but cannot be accessed.
How can I improve my memory for the KSEEB exams?
You can improve memory by using mnemonics, chunking large pieces of information, practicing elaborative rehearsal, getting adequate sleep, and revising regularly using active recall.
