The Difference between Short-Term, Long-Term and Working Memory<\/span><\/strong><\/h3>\n

For the most part,\u00a0memory and how it works has largely been a mystery to experts. However, what scientists do know is that memory is partitioned into several different parts\u2014primarily short-term memory, long-term memory, and\u00a0working memory.<\/p>\n

Working memory, short-term memory, and long-term memory all play an important role in remembering,\u00a0learning, and creating. It is safe to say that without memory, human progress would not exist.<\/p>\n

Short-term memory differs from long-term memory in two fundamental ways, with only short-term memory<\/span> demonstrating temporal decay and capacity limits<\/strong>. Long-term memory<\/span> however, can store vast amounts of information and is permanent.<\/strong><\/p>\n

Short-term memory gives the ability for the human brain to keep information in the mind for a very short period of time, such as remembering a phone number long enough until you are able to dial it on our phones. The extent of short-term memory lasts within seconds to minutes then dissipates if effort is not made to retain the information for long-term use.<\/span><\/p>\n

It is commonly believed that the capacity of short-term memory (and also working memory) is 7 +\/- 2. That is, on average, humans are able to hold seven random and unrelated objects simultaneously in the short-term memory bank, give or take 2. In other words, short-term memory holds about 5-9 items at one time<\/span>.\u00a0<\/p>\n

It is believed that short-term memory is a primary function of the prefrontal cortex<\/span>. Once memory is consolidated, it is carried over to the hippocampus wherein long-term memories are formed and stored permanently<\/span>. This conversion from short-term to long-term memory requires concerted effort, the passage of time, and the absence of interference in memory consolidation.<\/strong><\/p>\n

Things learned on a daily basis dissipate unless consolidation takes place, in which it is transferred into the long-term memory bank. So how does consolidation take place? It takes place with repetition and review.<\/strong> The more something is repeated and used, the more neuronal connections the brain makes<\/span>, wherein the neural pathways used for the specific information become stronger. In the process, the synapses become stronger between the two neurons as signals are more frequently passed between them. If short-term memory is consolidated and stored in the long-term memory, it becomes permanently ingrained, accessible for later use. If the memory does not consolidate, it will not be available for later use and access.\u00a0Ultimately, the role of short-term memory is to file information for temporary usage. If it is not consolidated, it is discarded.<\/strong> This process of discarding is important to make room for learning and new memories.\u00a0<\/p>\n

Each item passing through the short-term or working memory is ‘assigned’ a primal, emotional reaction.<\/strong> Sometimes these can be threatening and embedded into the long-term memory as such (i.e., difficulty experienced with a subject topic, for example, trigonometry > trigonometry is assigned an emotional memory). These emotions may even evoke a reaction –\u00a0fighting\u00a0<\/em>against the memory, or\u00a0fleeing<\/em> or ignoring the memory.\u00a0<\/p>\n

The central executive functioning region (located in the prefrontal cortex) seems to play a fundamental role in both short-term and working memory. The region serves as a temporary storage facility for short-term memory while at the same time making the memory available for recall and manipulation. The ability to manipulate information is essentially the theoretical difference between short-term memory and working memory. Short-term memory is used to describe the ability to store temporary information for immediate retrieval and discard<\/span>, while working memory is used to describe the use of information for manipulation.<\/span><\/strong><\/p>\n
