Class 11 Psychology - PUNJAB
Human Memory
The chapter 'Human Memory' in Class 11 Psychology explores how our mind encodes, stores, and retrieves information. Designed according to the Punjab School Education Board (PSEB) syllabus, it covers crucial information-processing models, including Atkinson and Shiffrin's stage model featuring sensory, short-term, and long-term memory. Students will study different types of memory like declarative and procedural, and various memory systems. Understanding these concepts is vital for board exams as questions frequently test the causes of forgetting, such as interference and decay, along with practical mnemonic techniques to improve memory performance.

Encoding
The first stage of memory where incoming information is received and translated into a usable neural format that the brain can understand and store.
Storage
The process of retaining and maintaining encoded information over periods of time, ranging from a few seconds to a lifetime.
Retrieval
The process of locating, accessing, and bringing stored information back into conscious awareness when needed.
Sensory Memory
The initial memory system that holds vast amounts of sensory input for an extremely brief duration, usually lasting less than a second.
Short-Term Memory (STM)
A working memory store that holds a limited amount of information (about 7 items) for a short duration of roughly 15 to 30 seconds.
Long-Term Memory (LTM)
The vast and relatively permanent storage system capable of holding unlimited amounts of information for extended periods.

Board Exam Info

Frequently Asked Questions
What is the difference between short-term memory and long-term memory?
Short-term memory has a very limited capacity (7 items) and duration (up to 30 seconds), whereas long-term memory has an unlimited capacity and can store information permanently.
Why do we forget things according to psychology?
Forgetting occurs due to various reasons including trace decay over time, interference from other memories, lack of proper retrieval cues, and motivated forgetting.
How can I improve my memory for the PSEB board exams?
You can improve memory by using mnemonic devices, chunking information, practicing elaborative rehearsal, getting enough sleep, and using distributed practice instead of cramming.
