Introduction to memory

For the journal of the same name, see Memory (diario) Memory is the ability of the brain to store, retain, and subsequently recall information. Although traditional studies of memory began in the realms of philosophy, the late nineteenth and early twentieth century put memory within the paradigms of cognitive psychology. In the recent decades, it has become one of the principal pillars of a new branch of science that represents a marriage between cognitive psychology and neuroscience, called cognitive neuroscience. There are several ways of classifying memories, based on duration, nature and retrieval of information. From an information processing perspective there are three main stages in the formation and retrieval of memory: Codificación (processing and combining of received information) Storage (creation of a permanent record of the encoded information) Retrieval/Recall (calling back the stored information in response to some cue for use in some process or activity) Contenido 1 Classification by duration 2 Classification by information type 3 Classification by temporal direction 4 Fisiología 5 Development of memory 6 Disorders 7 Memorization 8 Emotional Memory 9 Ver también 10 Referencias & Bibliografía 11 Textos clave 11.1 Libros 11.2 Papeles 12 Material adicional 12.1 Libros 12.2 Papeles 13 Otras lecturas 14 Relevant quotes 15 External links Classification by duration A basic and generally accepted classification of memory is based on the duration of memory retention, and identifies three distinct types of memory: sensory memory, short-term memory, and long-term memory. The sensory memory corresponds approximately to the initial moment that an item is perceived. Some of this information in the sensory area proceeds to the sensory store, which is referred to as short-term memory. Sensory memory is characterised by the duration of memory retention from milliseconds to seconds and short-term memory from seconds to minutes. These stores are generally characterised as of strictly limited capacity and duration, whereas in general stored information can be retrieved in a period of time which ranges from days to years; this type of memory is called long-term memory. It may be that short-term memory is supported by transient changes in neuronal communication, whereas long-term memories are maintained by more stable and permanent changes in neural structure that are dependent on protein synthesis. Some psychologists, sin embargo, argue that the distinction between long- and short-term memories is arbitrary, and is merely a reflection of differing levels of activation within a single store. If we are given a random seven-digit number, we may remember it only for a few seconds and then forget (short-term memory). Por otro lado, we can remember telephone numbers for many years (assuming we use them often enough). Those long-lasting memories are said to be stored in long-term memory. Additionally, the term working memory is used to refer to the short-term store needed for certain mental tasks - it is not a synonym for short-term memory, since it is defined not in terms of duration, but rather in terms of purpose. Some theories consider working memory to be the combination of short-term memory and some attentional control. Por ejemplo, when we are asked to mentally multiply 45 por 4, we have to perform a series of simple calculations (additions and multiplications) to arrive at the final answer. The ability to store the information regarding the instructions and intermediate results is what is referred to as working memory. Classification by information type Long-term memory can be divided into declarative (explicit) and procedural (implicit) memories. Declarative memory requires conscious recall, in that some conscious process must call back the information. It is sometimes called explicit memory, since it consists of information that is explicitly stored and retrieved. Declarative memory can be further sub-divided into semantic memory, which concerns facts taken independent of context; and episodic memory, which concerns information specific to a particular context, such as a time and place. Semantic memory allows the encoding of abstract knowledge about the world, como "Paris is the capital of France". memoria episódica, por otra parte, is used for more personal memories, such as the sensations, emotions, and personal associations of a particular place or time. Autobiographical memory - memory for particular events within one's own life - is generally viewed as either equivalent to, or a subset of, episodic memory. Visual memory is part of memory preserving some characteristics of our senses pertaining to visual experience. We are able to place in memory information that resembles objects, places, animals or people in sort of a mental image. Visual memory can result in priming and it is assumed some kind of perceptual representational system or PRS underlies this phenomenon. [1] En contraste, procedural memory (or implicit memory) is not based on the conscious recall of information, but on implicit learning. Procedural memory is primarily employed in learning motor skills and should be considered a subset of implicit memory. It is revealed when we do better in a given task due only to repetition - no new explicit memories have been formed, but we are unconsciously accessing aspects of those previous experiences. Procedural memory involved in motor learning depends on the cerebellum and basal ganglia. So far, nobody has successfully been able to isolate the time dependence of these suggested memory structures. Classification by temporal direction Prospective Memory: Tying ribbon or string around a finger is the iconic mnemonic device for remembering a particular thought, which one consciously trains oneself to associate with the string. A further major way to distinguish different memory functions is whether the content to be remembered is in the past, retrospective memory, or whether the content is to be remembered in the future, prospective memory. Así, retrospective memory as a category includes semantic memory and episodic/ autobiographical memory. En contraste, prospective memory is memory for future intentions, or remembering to remember (Winograd, 1988). Prospective memory can be further broken down into event- and time-based prospective remembering. Time-based prospective memories are triggered by a time-cue, such as going to the doctor (action) at 4pm (cue). Event-based prospective memories are intentions triggered by cues, such as remembering to post a letter (action) after seeing a mailbox (cue). Cues do not need to be related to the action (as the mailbox example is), and lists, sticky-notes, knotted hankerchiefs, or string around the finger (see box) are all examples of cues that are produced by people as a strategy to enhance prospective memory. Physiology Overall, the mechanisms of memory are not well understood. Brain areas such as the hippocampus, the amygdala, or the mammillary bodies are thought to be involved in certain kinds of memory. Por ejemplo, the hippocampus is believed to be involved in spatial learning and declarative learning. Damage to certain areas in patients and animal models and subsequent memory deficits is a primary source of information. Sin embargo, rather than implicating a specific area, it could be that damage to adjacent areas, or to a pathway traveling through the area is actually responsible for the observed deficit. Más lejos, it is not sufficient to describe memory, and its counterpart, aprendizaje, as solely dependent on specific brain regions. Learning and memory are attributed to changes in neuronal synapses, thought to be mediated by long-term potentiation and long-term depression. Main article: Neurophysiology of memory Development of memory As humans develop and mature their capacity for memory changes. Main article: Development of memory in childhood Main article: Aging and memory Disorders Much of the current knowledge of memory has come from studying memory disorders. Loss of memory is known as amnesia. There are many sorts of amnesia, and by studying their different forms, it has become possible to observe apparent defects in individual sub-systems of the brain's memory systems, and thus hypothesize their function in the normally working brain. Other neurological disorders such as Alzheimer's disease can also affect memory and cognition. Memorization Memorization, or rote learning, is a method of learning that conditions an individual to recall important information verbatim. This method of learning involves repetition, with the assumption that an individual can learn a necessary process or an amount of information through repetitive action or study, such to the point that it becomes near-automatic. Emotional Memory Main article: Emotion and Memory Hightened emotions can lead to experiences crystalizing into long-lasting and vivid memories. The Flash back's of Post traumatic stress disorder are one example of this. This boost in memory formation is partly due to the effects of the stress hormone norepinephrine. It appears that the hormone effects a receptor molecule called glautamate receptor 1 (GluR1) on nerve cell surfaces. The action appears to to be that Norepinephrine (a form of adrenaline triggers the attachment of a phosphate grroup to GluR1 and that this added phosphate group expedites the movement of GluR1 molecules to the surface, where they help cells form memories.[1] See also Aging and memory Alzheimers Amnesia Attention versus memory in prefrontal cortex Cellular memory Cues Cued recall Dementia Educational psychology Emotion and memory Evolution of memory False Memory Forgetting curve Genetic memory Hebbian learning History of memory research Human information storage Generation effect (aprendizaje) Involuntary Memory Kinesthetic learning List of memory biases Learning Long-term potentiation Matching to sample Memory bias Memory distrust syndrome Memory inhibition The Memory-Prediction Framework - an acclaimed "unifying theory of memory" Memory training Mindfulness Misinformation effect Mnemonic Muscle memory or proprioception - the sense and memory of how parts of the body are trained to move Neural adaptation Note taking Prompting Proprioception Recall (aprendizaje) Relearning Retention Rote learning Serial recall Source amnesia Synaptic plasticity Synaesthesia Tip-of-the-tongue Transsaccadic memory TRansactive memory References & Bibliografía ↑ Malinow, R., in Cell, Octubre 5, 2007 as reported in Science News, Octubre 20, 2007, 172(16), p. 254.

A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things, so that he has a difficulty in laying his hands upon it. Now the skilful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it - there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, por lo tanto, not to have useless facts elbowing out the useful ones."
