Human Memory

Human Memory, from Class 11 Psychology, Psychology, and the NCERT curriculum, explores how human beings encode, store, retain, and retrieve information over time. The chapter explains memory as a cognitive process consisting of three interconnected stages—encoding, storage, and retrieval. Students learn how information is processed through different memory systems and how memory supports learning, thinking, problem-solving, decision-making, and everyday functioning. The chapter also introduces the information processing approach and the influential Stage Model of Memory proposed by Atkinson and Shiffrin, which compares human memory with computer-based information processing systems.
 

The chapter provides a detailed understanding of sensory memory, short-term memory, long-term memory, and working memory, along with their characteristics, capacities, and functions. Learners explore important theories such as Craik and Lockhart’s Levels of Processing model, which highlights the importance of deep semantic processing for long-term retention. The chapter further examines various forms of long-term memory, including declarative, procedural, episodic, semantic, autobiographical, flashbulb, and implicit memory. Students also become familiar with methods used to measure memory, such as recall, recognition, sentence verification, and priming, while developing a deeper understanding of how information is organised and retained within the human memory system.
 

A major focus of the chapter is forgetting and memory improvement. Students study Ebbinghaus’s forgetting curve and various explanations of forgetting, including trace decay, interference, retrieval failure, and repressed memories. The chapter also introduces practical memory enhancement techniques such as chunking, keyword methods, method of loci, first-letter mnemonics, and the PQRST study strategy. By understanding the causes of forgetting and applying scientifically supported memory-improvement techniques, learners develop effective learning habits, stronger recall abilities, improved study skills, and a deeper appreciation of how memory shapes human behaviour and cognition.
