Key Concepts

Visuospatial Sketchpad

The visuospatial sketchpad is a subsystem dedicated to handling visual and spatial information. It allows for the temporary storage, maintenance, and manipulation of images and spatial data, supporting tasks like navigation, spatial reasoning, and visual problem-solving. Its function is essential for managing and interacting with visual contexts, thereby complementing the verbal processing of the phonological loop.

Working Memory

Working memory is a cognitive system responsible for the short-term storage and manipulation of information necessary for complex cognitive tasks such as reasoning, learning, and comprehension. It serves as a workspace where information is temporarily held and processed, allowing individuals to integrate new information with existing knowledge. This concept is central to understanding cognitive functions and limitations in processing capacity.

Central Executive

The central executive is the control system that directs and manages the operation of the subsidiary storage systems within working memory. It is responsible for selecting, coordinating, and regulating strategies for processing information, dividing attention, and shifting focus between tasks. As a supervisory component, it plays a crucial role in problem-solving and decision-making by integrating input from the phonological and visuospatial systems.

Phonological Loop

The phonological loop is a component specialized in processing and storing verbal and auditory information. It consists of a storage system that temporarily holds sound-based information and a rehearsal process that refreshes this information, preventing decay. This subsystem is critical for language comprehension, learning new vocabulary, and other tasks that involve auditory input.

Transcript

00:01 So this question is asking us to name and describe that atkinson's shiffron model.

00:06 So the atkinson shiff and model in the simplest terms describes stages in memory and memory storage.

00:16 They base this sort of model off of the fact or understanding that the way humans process and store information is very similar to that in how computers do.

00:30 So the first stage starts with sensory memory.

00:35 Sensory memory requires sensory input.

00:40 So i'm just gonna draw sensory input.

00:46 And sensory memory is a very short stage of the atkinson model, atkinson shiffin model, my bad.

00:54 And basically what happens here is it takes in information from the surroundings regarding the senses, and then deem certain things valuable.

01:08 So whatever is valuable is then relayed to the second part of the three stages of memory.

01:15 However, this sensory memory should be noted in that, yes, it deals with all the senses, but a lot of it, a lot of what is input is lost unless the brain deems it valuable in order to be retained.

01:32 So the second stage, so once input or specific memory is considered valuable, it reaches the second stage, which is short -term memory, also known as working memory.

01:57 So short -term memory, as the name suggests, is also a very brief stage in memory in that the notable number when thinking about short -term memory is.

02:10 7 plus or minus 2.

02:13 And this refers to the bits of info that a person's short -term memory is generally able to hold.

02:28 And this is obviously statistically speaking on average.

02:34 So being a stage of memory, it is something that memory passes.

02:39 And in order for memory to proceed to the third stage, the brain must undergo memory consolidation...
