74. What is Chunking?
Chunking, or grouping, is a way to memorize information when you have a long list to recall.
For example, if you’re going away on a trip and need to ensure you don’t forget to pack something, you can “chunk” your list by creating sub-categories.
It will be easier to remember your toiletries if you sub-categorize them as just that. Your toiletry list of soap, deodorant, toothbrush, toothpaste, razor, and towel is then much easier to remember than including it together with your travel list of iPod, snacks, and magazines, and your documentation list of passport, flight ticket, and hotel details.Chunking your long list into categories means your elaborative rehearsal technique allows for improved recall through longterm memory.
In cognitive psychology, chunking is a process by which individual pieces of an information set are bound together into a meaningful whole.[1] The chunks, by which the information is grouped, are meant to improve short-term retention of the material, thus bypassing the limited capacity of working memory and allowing the working memory to be more efficient. A chunk is a collection of basic units that have been grouped together and stored in a person’s memory. These chunks can be retrieved easily due to their coherent grouping.[5] It is believed that individuals create higher-order cognitive representations of the items within the chunk. The items are more easily remembered as a group than as the individual items themselves. These chunks can be highly subjective because they rely on an individual’s perceptions and past experiences, which are linked to the information set. The size of the chunks generally ranges from two to six items but often differs based on language and culture
75. What is rehearsal and repetition?
A rehearsal is an activity in the performing arts that occurs as preparation for a performance in music, theatre, dance and related arts, such as opera, musical theatre and film production. It is undertaken as a form of practising, to ensure that all details of the subsequent performance are adequately prepared and coordinated. The term rehearsal typically refers to ensemble activities undertaken by a group of people. For example, when a musician is preparing a piano concerto in their music studio, this is called practising, but when they practice it with an orchestra, this is called a rehearsal. The music rehearsal takes place in a music rehearsal space.
Repetition is the simple repeating of a word, within a short space of words (including in a poem), with no particular placement of the words to secure emphasis. It is a multilinguistic written or spoken device, frequently used in English and several other languages, such as Hindi and Chinese, and so rarely termed a figure of speech.
Its forms, many of which are listed below, have varying resonances to listing as a matter of trite logic often similar in effect.
