This allows data to be conveyed in the short term, without consolidating anything for permanent storage. From here a memory or an association may be chosen to become a long-term memory, or forgotten as the synaptic connections eventually weaken. The switch from short to long-term is the same concerning both implicit memory and explicit memory.
Neither holds information for long, but short-term memory is a simple store, while working memory allows it to be manipulated. [17] Short-term memory is part of working memory, but is not the same thing. Working memory refers to structures and processes used for temporarily storing and manipulating information.
Short-term memory is responsible for retaining and processing information very temporarily. It is the information that we are currently aware of thinking about. [2]: 13 Short term memory is also known as the working memory. The storage capacity and duration of short-term memory is very limited; information can be lost easily with distraction. [2]
According to Gazzaniga, "encoding is the processing of incoming information that creates memory traces to be stored." [1] There are two steps to the encoding process: "acquisition" and "consolidation". During the acquisition process, stimuli are committed to short term memory. [1]
As with sensory memory, the information that enters short-term memory decays and is lost, but the information in the short-term store has a longer duration, approximately 18–20 seconds when the information is not being actively rehearsed, [20] though it is possible that this depends on modality and could be as long as 30 seconds. [21]
Typical level-of-processing theory would predict that picture encodings would create deeper processing than lexical encoding. "Memory over the short term and the long term has been thought to differ in many ways in terms of capacity, the underlying neural substrates, and the types of processes that support performance." [13]
Patient KF was brain damaged, displaying difficulties regarding short-term memory. Recognition of sounds such as spoken numbers, letters, words, and easily identifiable noises (such as doorbells and cats meowing) were all impacted. Visual short-term memory was unaffected, suggesting a dichotomy between visual and audial memory. [51]
However, to explain the recall process, the memory model must identify how an encoded memory can reside in the memory storage for a prolonged period until the memory is accessed again, during the recall process; but not all models use the terminology of short-term and long-term memory to explain memory storage; the dual-store theory and a ...
