Short-Term And Working Memory Measurement


While long-term memory can store and modify information over a long time, short-term memory can generally hold information in an active state for a short time. Working memory is a type of short-term memory where one can store small amounts of information for a short while. An example is a phone number that was only recently recited and may be recalled via short-term memory. This includes remembering where one parked their car in the morning, what was eaten for lunch the previous day, and the intricacies of a book read a while ago. Working memory is the little size of information that can be maintained in the brain and used in cognitive activities. Working memory is the enormous amount of information that has been preserved over one’s life (Logie et al., 2021). Working memory is one of the most often used phrases in psychological research. Examples of working memory activities include remembering a person’s location while listening to directions on how to get there or listening to a story’s sequence of events while attempting to comprehend the story’s meaning.

Differences Between Short-Term and Working Memory

Working memory organizes and processes small bits of information for only a few seconds, while short-term memory holds information for only a few seconds. In short-term memory, information is retained in the short-term memory without being influenced, whereas information is retained and influenced in the working memory (Chai et al., 2018). It is common practice to utilize easy-span activities when assessing short-term memory; yet, while assessing working memory, it is more common to use challenging span tasks. Put another way, participants in fundamental span tasks are often required to recall a range of symbols and items and spatial locations for a short period.

How Scientists Measure Short-Term and Working Memory in the Lab

CogniFit’s comprehensive cognitive testing tool may efficiently evaluate working memory and processing speed. All CogniFit exams employ the Wechsler Memory Scale, CPT Continuous Performance Test (CPT), the TOMM, Visual Organization Task (VOT), and the Test of Attentional Variables (TAV) to evaluate working memory (Yu et al., 2018). A person’s ability to do tasks quickly and accurately is influenced by various factors. It includes working memory and short-term phonological memory, measured by these tests and working memory. WOM-ASM Sequencing Assessment: The screen displays a sequence of balls with varying numbers.

Memorizing the sequence is necessary for the user to repeat it later. The series continues to grow until the user commits a mistake. After each presentation, the user is prompted to repeat the series. A person sees three things on the screen during the WOM-REST test. The user must recall the three things on the screen as soon as possible. Four sets of three photos are shown, and the user must choose the proper sequence from the first screen from whence they appeared.

Wechsler Memory Scale (WMS), CPT, Test of Memory Malingering (TOMM), and Tower of London (TOL) tests influence CogniFit’s short-term memory assessments. Working memory, spatial perception, and processing speed are all part of these assessments. While examining the Order of WOM-ASM Events, one sees a succession of balls looking closely. The memory of the sequence of numbers is required, and the ability to repeat it (Le et al., 2019). The sequence is made up of just one number and is then increased by one number at a time. After each presentation, the user will have to go through the steps again. In the test of Concentration VISMEN-PLAN, the user must recall the sequence of three things shown on the screen. The user has to recall the sequence to choose the proper choice on the screen, and the things will vanish.

Subcomponents of Working Memory According to Alan Baddeley’s Model

Each component of Alan Baddeley’s Model has its distinct function. The central executive acts as a supervisory system, ensuring that data flows freely from and to its subordinate systems. Cognitive processes are controlled and regulated by the central executive system, a dynamic system (Nusslock et al., 2019). Working memory is enhanced due to its ability to concentrate attention and target specific pieces of information. It may be seen as a supervisory mechanism that monitors cognitive processes and intervenes when they go awry, preventing distractions and keeping the short-term store active.

It is via the phonological loop that phonological data is sent to the brain. Short-term phonological storage and articulatory rehearsal are the two components of this system. The phonological storage assumes that all heard linguistic information is immediately entered. Silent articulation may convert visual language into phonological coding stored in the brain’s phonological memory (Hseih et al., 2017). It is the articulatory control mechanism that aids in this metamorphosis. An inner ear stores speech sounds in the phonological store, while an inner voice repeats words or other speech aspects to keep them from fading away. Both processes are referred to as inner voices.

Short-term processing of a small number of sounds involves language and sub-vocal practices. Further sub-categories include phonological storage, which stores a few seconds of auditory information, and the act of talking to oneself. It is possible to employ the articulatory control mechanism to protect phonological information from deteriorating. If one is having trouble memorizing or recalling anything important such as a phone number or a process, they should try doing it quietly to help themselves get it back in their head.

The visuospatial sketchpad, referred to as the inner eye, is responsible for processing spatial and visual data. This information describes how things seem and plays a significant role in maintaining track of one’s location concerning other things as one navigates through their surroundings (Uttah et al., 2022). As one walks about, their location concerning things is continually changing; thus, everyone must have the ability to update this information. For instance, if one is aware of where the desks, tables, and chairs in a classroom are, they are less likely to bump into objects.

Neural Correlations of Working Memory

Working memory (WM) activity is influenced by aging, with older persons exhibiting more activity than younger individuals. Intelligent behavior, information processing, executive function, comprehension, learning, and problem-solving have all been associated with or connected to it in people of all ages and all sorts of animals, ranging from newborns to the aged. According to neuroscience, working memory involves the front parietal brain, which includes the prefrontal, parietal, and cingulate cortexes, among other locations (Baddley, 2000). Following the publication of these discoveries, it has been shown that working memory is associated with subcortical areas such as the midbrain and cerebellum.


In conclusion, memory storage may be demonstrated to move through a short-term phase, which decays until developed by the long-term storage process. This contrast between the biological long and short-term storage systems applies primarily to the physical aspects of the memory trace. Short, middle, and long-term memory is the terminology used by psychologists to split distinct phases in the conceptual processing of information, notably in verbal learning trials. The trials described in this paper primarily deal with periods greater than people’s short-term memory breakdown. The evolving landscape of the physical store is not evident in the barrier to the release of action reliant upon memory. The physiological temporal lobe presumably correlates to the basic type of information stored in the mind.
