Memory is a fundamental aspect of human psychology that plays a crucial role in our daily lives. It allows us to store and retrieve information, enabling us to learn from our experiences and navigate the world around us. In this essay, we will explore the various models of memory that have been proposed by psychologists and examine the key features of each model.

One of the earliest models of memory is the three-stage model, which was proposed by Atkinson and Shiffrin in 1968. According to this model, memory consists of three stages: sensory memory, short-term memory, and long-term memory. Sensory memory is a temporary storage system that holds information from the senses for a brief period of time, typically just a few seconds. Short-term memory, also known as working memory, is a more limited system that can hold information for a longer period of time, typically up to about 20 minutes. Finally, long-term memory is a more permanent system that can hold information indefinitely.

Another influential model of memory is the multi-store model, which was proposed by Baddeley and Hitch in 1974. This model suggests that there are multiple stores of memory, including a phonological loop (for storing verbal information), a visuospatial sketchpad (for storing visual and spatial information), and a central executive (for coordinating the activity of the other two stores and controlling the flow of information).

The dual-coding theory, proposed by Paivio in 1971, suggests that there are two distinct systems for encoding and storing information in memory: a verbal system for storing linguistic information and a nonverbal system for storing visual and spatial information. According to this theory, these two systems interact and influence one another, with the nonverbal system often providing additional support for the verbal system.

The concept of encoding, or the process of transforming information into a form that can be stored in memory, is also important in understanding memory. Research has shown that different types of encoding, such as visual, auditory, and semantic encoding, can affect the strength and durability of a memory.

One model that focuses specifically on the process of encoding is the Levels of Processing theory, proposed by Craik and Lockhart in 1972. This theory suggests that the deeper and more meaningful the processing of information, the more likely it is to be remembered. For example, if you were trying to memorize a list of words, you might have better recall if you think about the meaning of each word and how it relates to other words, rather than just repeating the words over and over.

Finally, the concept of retrieval, or the process of accessing and recalling information from memory, is also important in understanding memory. The retrieval process can be influenced by various factors, such as the context in which the information was learned and the emotional state of the individual at the time of retrieval.

In conclusion, the study of memory is a complex and multifaceted field of psychology that has yielded a wide range of models and theories. Each model offers important insights into the nature of memory and the processes involved in storing and retrieving information. Understanding these models can help us better understand how memory works and how to improve our own memory skills.

Novel interventions are thus more likely to be successful if they target EFs such as WM that are not only deficient in ADHD, but also related to the primary behavioral and learning functional impairments associated with the disorder. Each of these elements has a set of cognitive nodes and a set of emotion nodes along with one or two sets of emotion intensity nodes, as described above, to enable mixing emotions of the same or different intensities. Case studies of individuals with brain damage that affects procedural memory but not declarative memory is needed to understand this better, however, such cases are extremely rare. Practical Psychology Practical Psychology began as a collection of study material for psychology students in 2016, created by a student in the field. Performing a concurrent task — tracking an overhead swinging pendulum — disrupted recall in the spatial but not the nonsense condition. Memory system Process of memory 1. Information in the STM is coded mainly acoustically.

Not all of these are mutually exclusive and many types of memory overlap with each other based on the content of memory, how it is remembered, and how it is encoded. The memory matrix of the Bidirectional Associative Memory BAM model discussed by Tryon 1999 and reviewed in Chapter 11 is composed of the outer matrix multiplication of the stimulus microfeatures associated with the two elements being associated in memory, but is illustrated below as Figure 5. This includes performance, physiological arousal and also cognitive anxiety too. Retrieval Recovery of stored information We recall or bring a memory into consciousness, from among the stored materials. An additional component was added called the episodic buffer.

For example, the working memory of a story will likely contain visual, semantic, and chronological information i. Research has shown that one of the critical factors that influence memory failure is time. American Psychologist, 56, 851—864. Memory is formed sequentially, and information passes from one store component in the model to the next in a fixed and linear order. The sensory stores constantly receive information, but most of this information is not attended to and remains in memory very briefly.

Dual task studies have played an important role in illuminating the functional organization of the visuospatial sketchpad. The results showed that participants could recall an average of 7. The research demonstrated the existence of iconic memory Sperling, 1960. Riding a bicycle is a perfect example of this, as is the knowledge or memory of any skill. The Modal Model of Memory, also known as the Multi Store Model of Memory, is a theory that was developed by The Modal Model of Memory explains how memory processes work. We use episodic memory when we learn lists of words or when we need to recall something that occurred to us at a particular time or in a particular context. The Working Memory Model Baddeley and Hitch, 1974 Working memory is The phonological loop is a component of working memory model that deals with spoken and written material.

Memory, Encoding Storage and Retrieval

Retrieval failure theories argue forgetting from the long-term memory is caused by failing to access the memory due to insufficient clues or cues to aid recall rather than it being unavailable. If the information is focused on, it then enters the STM. The locus of this effect is the phonological store, and it results from the increased amount of interference that occurs between memory traces that share overlapping representational e. These memory stores differ in how information is encoded, memory storage capacity and how long information is stored duration. This limitation needs the usage of procedural memory which we will look at in subsequent models. For example, the spatial layout of your house is held in LTM. However, evidence from patients suffering from amnesia suggests that this is not true.

Objective evidence in support of the Working Memory Model comes from PET scans which show different parts of the brain become activated when doing visual and verbal tasks. He found that acoustically similar words were harder to recall immediately, and semantically similar words were harder to recall 20 minutes after the test. This process is perhaps overly strict in this model as the model requires episodic memory to be dependent on semantic memory. For instance, if you associate a person you just meet with someone you already know, you may be able to remember their name better. It should be noted that working memory has been link to higher Without going into detail, there are 3 main parts of working memory: the Visuospatial Sketchpad, the Phonological Loop, and the Episodic buffer. This process is known as retrieval process. Rather than hitting a cyclist who is wobbling all over the road, it is preferable to stop talking and concentrate on driving.

Within the phonological loop, two interacting components—the phonological store and the articulatory rehearsal process—enable verbal representations to be maintained in an active state. Retrieval Failure — an explanation for forgetting. Cambridge, England: Cambridge University Press. These include recognizing the pattern of filled squares in a two-dimensional grid Phillips and Christie, 1977; Wilson et al. Trends in Cognitive Sciences, 4, 11 : 417-423. This supports theories for 3 distinct stores of long-term memory.

This system accounts for remembering facts, life episodes, trivial and significant experiences, thoughts, conversations, faces, etc. The Visuospatial Sketchpad The Visuospatial Sketchpad the visuospatial sketchpad inner eye deals with visual and spatial information. Short-Term Memory Short-term memory is the storage of memory available for a short time only around 30 seconds. It basically contains all the information that an individual is currently thinking about. Retroactive interference RI occurs backwards in time when the coding of new information disrupts previously stored information. So then, stoking a campfire is mostly about expanding the flame itself, not the minutiae of smoke or sound.
