Memory in psychology. Properties, types, processes, functions, definition, violations, patterns, classification, mechanisms

Personal development presupposes the accumulation of existential experience by an individual, which requires a person to update all thought processes, including memorization processes. Taking into account the multidimensionality of memory as a psychological phenomenon, it is quite problematic to give an unambiguous definition of a psychological property.

Definition 1

In the most general form, memory is understood as a mental property of a person, its ability to accumulate, store and reproduce information and experience; the ability to remember and reproduce individual experiences of the past, realizing not only the experience itself, but also its place in the individual history of the individual.

Definition

Memory is involved in processing a huge amount of information. This information takes many different forms, such as images, sounds, or meanings.

For psychologists, the term “memory” covers 3 important aspects of information processing:

Memory encoding. When information enters the memory system (from sensory input), it must be converted into a form that the system can handle so that it can be stored.
Memory capacity. How data is stored affects how it is processed in the future. Miller put forward this idea in 1957 and called it the magic number 7. According to him, the capacity of short-term memory was 7-9 items because it only had a certain number of “slots” in which items could be stored.
Memory restoration. This refers to retrieving information from storage. When a person is asked to retrieve something from memory, the differences between short-term (STM) and long-term (LTM) memory become very clear. STM is stored and retrieved sequentially. LTM is stored and retrieved by the association.

There are 3 main ways to encode (change) information:

visual (picture);
acoustic (sound);
semantic (meaning).

Most memory research is based on experiments conducted in laboratories. Psychologists use the term "ecological validity" to refer to the extent to which research findings can be generalized to other settings.

Memory in psychology (the properties of long-term and short-term memory are still poorly understood) has been tested through experiments. They have high ecological validity if the results can be generalized, applied, or extended to settings outside the laboratory.

It is often assumed that if an experiment is realistic or plausible, then there is a high probability that its results can be generalized. If this is not realistic (if the laboratory conditions and tasks are staged), then the results are less likely to be generalizable across situations.

Kinds

Memory was a subject of study among many 20th century psychologists, and remains an active area of study for modern cognitive scientists:

Creator	Characteristics of experiments
Multiple department model (Atkinson and Shiffrin, 1968)	In 1968, Richard Atkinson and Richard Shiffrin proposed an influential theory of memory known as the multiple compartment model. This model assumes that information exists in one of 3 memory states: sensory, short-term, and long-term storage. Information comes into memory from the senses - for example, the eyes see a picture, the olfactory receptors in the nose can smell coffee or the ear can hear a piece of music. This stream of information is stored in the sensory memory store, and because it consists of a huge amount of data, only a small part of it needs to be remembered.
Levels of Processing (Craik & Lockhart, 1972)	Fergus Craik and Robert Lockhart criticized the multicompartment model's explanation of memory, so in 1972 they proposed an alternative explanation known as levels of processing effect. According to this model, memories are not stored in 3 compartments; instead, the strength of the memory trace depends on the quality of processing or rehearsal of the stimulus. In other words, the more a person thinks about something, the longer the memory of it remains.
Working memory model (Baddeley & Hitch, 1974)	While the multiple compartment model provided compelling insight into how sensory information is filtered and made available for recall according to its importance, Alan Baddeley and Graham Hitch viewed short-term memory (STM) storage as a complete, simplified phenomenon and proposed a model of working memory , which will replace STM. It relies on two components, the visuospatial sketchpad (inner eye) and the articulatory-phonological loop (inner ear), which focus on different types of sensory information. The visuospatial sketchpad also allows a person to recall and review visual information stored in long-term memory. The articulatory-phonological loop processes sounds and voices that are heard.
Miller's Magic Number (Miller, 1956)	Prior to the working memory model, American cognitive psychologist George A. Miller questioned the limits of short-term memory capacity. In a famous 1956 paper published in the journal Psychological Review, Miller referred to the results of previous memory experiments, concluding that people can typically store on average only 7 blocks of information in the short term. Miller realized that the brain is capable of “combining” pieces of information, and these pieces count towards the 7-digit STM block limit. For example, a long word consists of many letters that form numerous phonemes. Instead of remembering a 7-letter word, the mind “recodes” it by combining individual pieces of data. This process allows you to increase your memory limits to a list of 7 individual words.
Memory Decay (Peterson, 1959)	Following Miller's "magic number" paper on short-term memory capacity, Peterson decided to measure the longevity of memories. In an experiment using the Brown-Peterson task, participants were given a list of trigrams—nonsense lists of 3 letters (e.g., GRT, PXM, RBZ)—to remember. After the trigrams were shown, participants were asked to count the number and recall the trigrams at different times after memorizing them. Despite the fact that almost all participants could initially remember the trigrams, after 18 sec. The accuracy of the experiment dropped to about 10%. Peterson's research demonstrated the surprising brevity of memories in the short-term compartment of the brain before decay affected the ability to remember them.
Flash of Memory (Brown and Kulik, 1977)	When news of the death of a famous person spread throughout the world, people began to “remember” their activities at that moment. Psychologists Roger Brown and James Kulik recognized this phenomenon of memory back in 1977. A person can remember minute details of personal circumstances while participating in other mundane activities. Moreover, you don't have to be personally involved with an event for it to affect people's lives.
Memory and smell	The connection between memory and smell helps many species of living organisms survive. The ability to remember and later recognize odors allows animals to detect the nearby presence of members of the same group, potential prey and predators. Researchers at the University of North Carolina tested olfactory effects on memory encoding and retrieval in a 1989 experiment. Male college students were shown a series of slides of photographs of women whose attractiveness they were asked to rate on a scale. Results showed that participants were better able to recall memories when the odor during encoding was the same as the odor during revision (Cann and Ross, 1989). These results suggest that the connection between the sense of smell and memories is conserved.
False Memories	This idea may sound like the stuff of dystopian science fiction, but evidence suggests that memories a person already has can be manipulated long after they are encoded. If a group of people is shown a video with a tragic ending, he will definitely name the culprit, based on the thoughts that he has formed within his brain activity.

Memory in psychology, the properties of which explain the process of encoding and storing information, can be divided into several types. Depending on the type of brain process, people use recently acquired information or old information that has been stored for several years.

What influences memorization?

Taking into account and using individual inclinations and habits when memorizing.
How often we repeat material (“repetition is the mother of learning”).
The presence of emotional coloring (it improves the memorization of material, and even a negative emotional background is preferable to a neutral one. But the emotion should not be too strong).
The volume of material, its structure, meaningfulness.
Age nuances.
Availability of conditions for memorization (settings, distractions, etc.).
Internal state (motivation, focus, state of mind, etc.).
Technologies used in memorization (mnemonics techniques, pace of information input, etc.).

A few tips to help improve memory productivity:

Formulate the memorization task correctly: it must meet the requirements for reproduction.
Choose the most important thing in the material, and cut off everything unimportant.
Decide how the material should be organized and what will serve as the operational unit and memory code.
Use all your senses as fully as possible.

How to improve memory for an adult? To improve memory, you also need to learn, when working through new material, to introduce it into the system of existing knowledge, which means to be attentive, be able to observe, concentrate, repeat learned material and use auxiliary means (for example, mnemonics techniques). Sufficient motivation to remember and reproduce and compliance with the goals that a person wants to achieve is also important.

Memory is inextricably linked with other mental processes. Thus, without achieving stable attention, or being psychologically unable to concentrate, or not having time to organize information, we cannot expect good memorization.

By training memory, attention, thinking, perception, we expand our cognitive capabilities and develop the cognitive functions of the brain. You can regularly train your memory and other cognitive abilities with the help of special memory training exercises.

We wish you success in self-development!

Processes

People first process stimuli through their sensory memory—this information is typically stored in the brain for less than a second. The information is then transferred to short-term memory, or working memory, which allows you to think things through and store key points in your mind. Finally, past events enter long-term memory (episodic or semantic).

Different areas of the brain influence aspects of memory.

For example, the hippocampus is associated with spatial memory, which helps the brain map the world around it and bypass negative emotions:

To form new memories, information must be converted into a usable form, which occurs through a process known as encoding. Once information has been successfully encoded, it must be stored in memory for later use. Most of this stored memory lies outside of consciousness most of the time, except when you really need to use it. The retrieval process brings stored memories into the conscious part of the brain.
Sensory memory is the earliest stage of information processing. At this stage, sensory information from the environment is stored for a very short period of time, usually no more than ½ second. for visual information, and 3 or 4 sec. for auditory information. Short-term memory, also known as active memory, is information that a person is currently aware of or thinking about. In Freudian psychology, this memory is called the conscious mind.
Paying attention to sensory memories generates information in short-term memory. Most of the information stored in active memory will be there for about 20-30 seconds.
Long-term memory refers to the permanent storage of information. In Freudian psychology, long-term memory can be called preconscious and unconscious. This information is largely beyond comprehension, but can be transferred into working memory and used as needed. Some of this information is quite easy to remember, while other memories are much more difficult to access.

Clustering is used to organize related information into groups. Information that is categorized becomes easier to remember and recall.

Stages of information processing when memorizing

If we talk about the structure and mechanism of perception, analysis and sending for storage into memory of any information received, then this happens at the following levels.

Sensory processing of any data. Fractions of a second are allotted for this period. Everything is remembered briefly and put aside for longer storage only if it has been analyzed as valuable.
At the next stage, the received data is sent for storage. If they are used in the very near future and a person uses them almost immediately, then this type is called short-term. This includes, for example, orders at work that need to be completed during the current working day.
Next comes long-term or long-term. This place is a repository for everything important that will be used over a long period of life. As a rule, this includes all acquired skills and life experience, knowledge and abilities, memories and impressions.
RAM is similar to internal computer memory. This type is used when you need to work with small amounts of information over a long period of time. Despite its similarity with short-term, there are still certain differences between them.
Tertiary memory refers to long-term memory. Most often used to store language arrays.

Characteristics and properties

Memory in psychology is divided into short-term and long-term. These are the 2 main types that should be analyzed for common characteristics.

Their properties also depend on the following criteria:

Brief duration that can last up to 20 seconds.
Its capacity is limited to 7 ± 2 “portions” of independent information (Miller's law) and is vulnerable to interference and interruptions.
The fading of such memory occurs while taking medication or as a result of injury.

Short-term memory is responsible for 3 operations:

Visual interpretation, which is the ability to store images.
Acoustic imagination, which is the ability to store sounds.
Working memory, which is the ability to store information before using it.

Information in long-term memory is stored as a network of schemas, which are then converted into knowledge structures. That is why a person remembers relevant knowledge when he comes across such information.

There are 2 types of long-term memory:

Explicit: conscious memories that include perceptions of the world as well as one's own personal experiences.
Implicit: unconscious memories that have been used without awareness.

Long-term memory is responsible for 3 operations:

Coding, which is the ability to transform information into a knowledge structure.
Storage, which is the ability to accumulate pieces of information.
Search, that is, the ability to remember things that are already known to a person.

Setting tasks for a person provokes memorization - a work plan, further memorization and use of acquired skills. According to S. L. Rubinstein, memory helps to remember moments that depend on the situation in which they were remembered. And the research of P.I. Zinchenko proves that the mindset of memorization is a direct goal for the action of the brain.

If information is remembered by itself, then a person will better use brain data. Random memorization of pictures and telephone numbers indicates that the brain is not afraid of the tasks assigned to it. Otherwise, if you are forced to learn a poem, a person will be more difficult to succumb to this process.

A. A. Smirnov's research was devoted to the main problem of memorization. Productive unconscious thinking was analyzed during the experiment. Specific conditions were created in which a person remembered all the details of the events taking place, but he was not asked to do so.

Under the same conditions, he was given the task of learning the rules of the organization, which he failed to do. These exercises made it possible to introduce a process of analyzing situations into the education system so that workers and students could quickly integrate into the process of ongoing actions.

Memory in psychology. Properties

Psychologist Ebbinghaus studied the volume of such memory and came to the conclusion that it is easier for a subject to remember 5-7 words of unknown meaning. “Clean” memory produced a result that was ½ less than the initial one. However, several days later the person did not remember a single word.

This experiment gave rise to a new definition - mechanical and meaningful memorization:

In the first case, mechanical actions are aimed at ensuring that a person remembers which foot he took a step from in order to repeat it in the future. This principle helps to work with athletes. The connection of neurons allows you to scroll through information in your head, which then “works” for the result. Complex elements in sports were performed as refined movements, thanks to the fact that a person “played out” their execution technique several times in his head. The deceived brain thought that the human body could work in this direction.
Meaningful memorization involves isolating the main and important information from the pure flow of knowledge. This technique is still used in theories and practices at universities. When giving a lecture, the teacher points out important points that need to be remembered. They allow students to build on them, developing thoughts to specific events. They, in turn, remain in the unconscious part of memory. When you need to use data, the brain “opens” the door to it.
The logical combined method of memorization was founded by M. N. Shardakov, who provided people with the opportunity to remember events evenly and in the required sequence. If the chronology of information reproduction was violated, the memorization tactics changed. The goal of the task was for children and adults to learn information in doses, remembering it in full. No one was able to learn entire poems without fragmentation, despite attempts to convey sounds through music.

The combined type can be used to learn a foreign language. The unconscious and logical method allows you to remember the theory and apply it in practice, while the intentional (force) method practically does not produce results.

Methods of training and development

If a person does not have physiological disorders, he can improve memory function: speed up memorization and increase volume. Simple exercises designed for children and adults are suitable for this.

Development in children

You can notice a lag in the development of memory in children at a young age, but until the age of 3-4 years, parents do not worry about it, and turn to a psychologist when the child is about to go to 1st grade. And although time is lost, the situation can be helped.

To develop visual memory, the “Story Pictures” method is used. Cards are laid out in front of the child, depicting a short story. The preschooler examines it for some time. When he is ready, the adult needs to swap the cards. The child’s task is to restore the sequence of actions. For auditory memory, exercises for memorizing words and numbers are suitable. You need to start with three, gradually working up to 6–7.

Development in adults

You can train your memorization skill with any material: retell the plot of a movie, memorize poems, phone numbers, words of a foreign language. You can study during a break at work, using improvised objects. For example, lay out stationery on the table, take a photo, change places and arrange them as they were in the beginning.

Functions and role

Memory in psychology (memory properties are directly related to its role and functions performed by it) is divided into several types depending on the functions performed in a person’s life:

Function	Peculiarity
Reflective	Memory is capable of reflecting events that are stored in it in order to remind a person of the consequences. Here we can give an example of “déjà vu,” when a person remembers a number of situations and the moment of his behavior under certain circumstances.
Regulatory	I. P. Pavlova in her research talks about associations that help establish strength between events of different times.

Modern science in the works of P.K. Anokhin explores hypotheses about the mechanism of memory. Biocurrents that are independently renewed in nerve cells help create the effect of visual perception. This is an experiment conducted by P. P. Blonsky, which is based on a mental phenomenon. The act of cognition of a situation occurs due to orientation in the information in the depths of the brain.

The role of memory in human life occupies a dominant niche in the work of the nerve endings of the cerebral cortex. A lawyer must remember the information of all persons participating in the process, a lawyer must remember the theory and veracity of situations. A simple worker must determine the logic of sequential actions. In science they distinguish:

Explicit memory	Refers to knowledge or experience that can be consciously remembered.
Episodic and semantic	Episodic memory refers to the immediate experience that has been acquired. Semantic memory refers to knowledge of facts and concepts about the world.
Implicit memory	Implicit memory refers to the influence of experience on behavior, even if the person is not aware of these influences.
Procedural memory	It refers to the often inexplicable knowledge of how to do something. For example, make tea or open the door.

There is another type of implicit memory - these are effects that help to effortlessly reproduce what neutral stimuli in the brain help us remember through associations. A person may unconsciously turn towards a sound or bright light.

Short-term memory

When highlighting types of memory in psychology, long-term and short-term memory are most often mentioned first. The latter is a method of storing information for a short period of time, usually from 20 to 30 seconds. Very often the physical memory of a computer is compared with it.

Short-term memory retains a generalized image of an object that a person has perceived. It focuses on the most basic and prominent features, the most memorable elements. Short-term memory functions without a preliminary setting for memorization. However, it is aimed at reproducing the information just received.

The main indicator characterizing short-term memory is its volume. It is determined by the number of units of information that a person will be able to reproduce with absolute accuracy 20-30 seconds after some data has been presented to him once. Most often, people's short-term memory capacity varies between 5 and 9 units.

Information is retained in short-term memory through repetition. Data is scanned by our brain using vision and then spoken through inner speech. After this, short-term auditory memory begins to work. In the absence of repetition, stored elements are forgotten over time or replaced by newly arrived data.

Violations

Memory in psychology, whose properties are also uncontrollable events and their consequences, can be subject to minor and serious failures:

Forgetting is a surprisingly common event that can occur for a number of reasons, including inability to remember the time period.
Dementia also affects thinking, judgment and behavior (Alzheimer's disease, progressive supranuclear palsy, normal pressure hydrocephalus, Creutzfeldt-Jakob disease).
Brain infections (Lyme disease, syphilis or HIV) can cause complete amnesia.
Parkinson's or Huntington's disease (multiple sclerosis) lead to the destruction of connections between neurons.

To identify the likelihood of mental disorders at an early stage, it is necessary to conduct a diagnosis.

Diagnostics

To diagnose mental and psychological characteristics of memory, testing is carried out:

A. R. Luria - “learning 10 words.” The purpose of the experiment is to test the level of memory development.
The method of “determining short-term memory” developed by G.I. Nevelskoy makes it possible to determine the accuracy and identity of memorization. In the experiment, individuals are given numbers arranged randomly. They need to be reproduced orally or in writing at the required speed.
Testing “visual memory” using I. Melnikov’s method involves proofreading the story. The subject must write down the words that he remembers. The level of auditory memory is assessed in the same way.

Diagnostics can be carried out in Moscow at the Gerontological Clinical Center, at the Center for Psychological Diagnostics and at the Clinical Psychiatric Hospital. The procedure may be repeated depending on the accuracy and purity of the experiment. If the results are not obtained, a repeat examination is carried out. The cost of testing can vary from 2300 to 8900 rubles.

Management methods

Methods for implementing memory functions may imply specific events and actions that are set as a task for the subject.

Mnemonic technique

The essence of the method is to use local binding of verbal intermediaries and divide them into groups.

A person learns a number of elements, compares them and remembers them. J. Bruno developed a methodology to establish the ability to interpret the result obtained in the study. A mnemonic technique allows you to teach a person to evaluate the brain’s ability to hide useless information.

Association method in neural networks

The technique was developed by P.I. Zinchenko. The point is that a person should be able to assemble objects using associative thinking, remembering their role in a person’s life. For example, you need to connect a number of useful actions, correlating their functions to a number of objects. Thus, a person remembers more words, interpreting the result through memories in action.

Flying technology for forgetting and suppressing memories

It was developed by O. L. Podlinyaev, who forced mentally ill people to forget about past negative events in life.

The goal of the technique is to be able to manage the long-term part of memory in the context of neural networks. Suppression of obsessively traumatic events occurs through writing a “burning letter”, emotions that were caused in the past years, and burning emotional complexes.

This technique can involve people in whom simple memory plots cause disturbances in consciousness. For example, a person cannot come to terms with the loss of a loved one and reacts negatively to fire (the fire claimed the lives of relatives). The technique allows you to “let go” of memories and suppress their reaction to the current event (bonfire, burning candle) by burning the sheet on which the emotions are written.

Harris's Mnemonic Devices (1980)

Harris once created an amazing methodology for memory training. The method helped people remember so quickly and store information in the sensory and short-term memory sections for a long time that they inevitably became targets for others. They were able to memorize a deck of cards and magician's techniques, which is why they were considered scammers.

Harris was unable to debunk the myth about these people, since he only created a technique for memory training. To manage such possibilities and learn to suppress rapid memorization syndromes, mnemonist Shereshevsky created synesthesia, which helped disrupt the process of information exchange in the sphere of the phenomenal technique of memorizing everything around.

The essence of the method was that when one area of the brain is irritated, impulses characteristic of the work of another area are activated. Thus, having pushed a person into the abyss, he should not be confused, but rejoice.

This substitution of impulses in the functioning of neurons helped Shereshevsky associate numbers and words with images of people. He also created a technique for forgetting this technique, returning a person to the body’s usual reactions.

Having managed to change the properties of all parts of memory, Shereshevsky created a psychological weapon with which he could control memory. In psychology there are many methods that allow you to manage emotions, thoughts and associative thinking. By studying and interpreting the workings of these parts of the brain, it is possible to control a person and manipulate his feelings to treat diseases.
