Human Memory | Class 11 Psychology Notes

Human Memory – this guide gives you a concise, exam-ready overview of Human Memory from Class 11 Psychology, written by ConceptScroll editors and reviewed against the latest NCERT textbook.

Enhancing Memory

Improving memory involves using strategies called mnemonics, which aid in encoding, storing, and retrieving information effectively. Mnemonics using images include the keyword method and the method of loci. The keyword method involves associating a foreign word with a similar-sounding English word (keyword) and creating vivid mental images linking the two. For example, to remember the Spanish word 'Pato' (duck), one might use 'pot' as the keyword and imagine a duck in a pot of water. The method of loci involves placing items to be remembered along a familiar physical route or location, creating visual images of the items at specific places. This is useful for remembering items in order, such as a shopping list. Mnemonics using organization include chunking, which groups smaller units into larger meaningful units to increase memory capacity, and the first letter technique, which forms acronyms or sentences from initial letters of items to be remembered (e.g., VIBGYOR for rainbow colors). Beyond mnemonics, memory improvement requires deep processing of information by elaborating meaning, minimizing interference by spacing learning sessions and varying subjects, and creating effective retrieval cues. The PQRST method (Preview, Question, Read, Self-recitation, Test) is a comprehensive strategy that encourages active engagement with material for better retention. Overall, memory enhancement is multifaceted and depends on health, motivation, familiarity, and appropriate strategy use.

🧪 Activity: Activity 6.4: Memorizing two lists of animal names, engaging in an unrelated activity, and comparing recall to observe effects of interference and rehearsal.

🔗 Connection: This section concludes with key terms, summary, review questions, and project ideas for reinforcing memory concepts.

Frequently asked questions

I. Try to remember the following list of digits (individual digits) 19254981121 Now try to memorise them in the following groups: 19254981121 Finally memorise them in the following manner: 1² 3² 5² 7² 9² 11² What difference do you observe? II. Read out the lists given below in a row at the speed of one digit per second to your friend and ask her/him to repeat all the digits in the same order: | List | Digits | | --- | --- | | 1 (6 digits) | 2-6-3-8-3-4 | | 2 (7 digits) | 7-4-8-2-4-1-2 | | 3 (8 digits) | 4-3-7-2-9-0-3-6 | | 4 (10 digits) | 9-2-4-1-7-8-2-6-5-3 | | 5 (12 digits) | 8-2-5-4-7-4-7-7-3-9-1-6 | Remember that your friend will recall the digits as soon as you finish the list. Note how many digits are recalled. The memory score of your friend will be the number of digits correctly recalled by her/him. Discuss your findings with your classmates and teacher.

Part I: When you try to remember the digits as individual digits (19254981121), it is difficult to recall all digits correctly because the number of digits exceeds the typical STM capacity (7 ± 2). When you try to memorize them in groups (chunking), it becomes easier to remember because chunking reduces the number of units to be remembered. Finally, when you memorize them as squares of odd numbers (1² 3² 5² 7² 9² 11²), it becomes even easier because you are associating the digits with meaningful

1. What is the meaning of the terms 'encoding', 'storage' and 'retrieval'?

Encoding is the process of converting sensory input into a form that can be stored in memory. Storage refers to maintaining the encoded information over time. Retrieval is the process of accessing and bringing stored information into conscious awareness when needed.

2. How is information processed through sensory, short-term and long-term memory systems?

Information first enters sensory memory where it is briefly held in its raw sensory form. If attended to, it moves into short-term memory (STM), where it is held temporarily and can be manipulated. Through rehearsal and encoding, information can be transferred to long-term memory (LTM), where it is stored more permanently and can be retrieved later.

3. How are maintenance rehearsals different from elaborative rehearsals?

Maintenance rehearsal involves simple, repetitive review of information to keep it in short-term memory. Elaborative rehearsal involves linking new information with existing knowledge, creating meaningful associations to facilitate transfer to long-term memory.
