Attention is divided into three mechanisms: selective, divided, and sustained attention. The selectivity of attention can be easily shown in studies that indicate that we focus only on some details of interest to us, and add what is missing based on what we remember. In general, the complex process of attention is a mechanism that integrates and involves feelings, emotions, and physiological structures that allow our mind to access all existing stimuli. It gives us the ability to select, distribute, and give our own meaning to each thing, object, or place, so that we can discriminate how pleasant and interesting a given event seems to us, in order to effectively guide our tastes, aspirations, and individual potential and to better integrate ourselves socially. What kind of ability is attention? Psychologists have not yet agreed on this; some consider attention to be just one aspect of perception and other cognitive abilities. We choose what we will see or hear by anticipating the structured information it will provide. Only those episodes to which we pay attention are anticipated, explored, and recorded; in other words, the act of perceiving requires selectivity. The selective nature of attention can be easily demonstrated; one way to do this is by recording people’s eye movements as they look at paintings or photographs. Studies of this kind indicate that we focus only on certain details; then, based on these cues, we fill in the missing information, perhaps drawing on memories. Evidence supporting selective attention also comes from divided attention studies. People can learn to perform two complex tasks simultaneously, but there are well-defined limitations. In general, attentional capacity depends on the resources required for the tasks being attempted. If few resources and conscious control are needed, a person can perform other tasks concurrently. If the task is far from automatic, it will require a significant amount of the person performing it. If one wants to perform two difficult tasks simultaneously, it is necessary to practice one of them first until it becomes relatively automatic and requires little attention. The environment in which we live is complex because it includes a large amount of information that we must attend to and sometimes requires us to respond to more than one piece of information simultaneously. When attentional and memory processes are activated, we are more receptive to events in the environment and perform an activity or task more effectively, even if it requires more effort. Through care we become aware of the physiological and pathological changes in our internal environment, whether physical or mental. Attention does not function in isolation, but is directly related to other psychological processes such as memory. # THE BIOLOGICAL VIEW OF MEMORY With the advances neuroscience has made in understanding how memory works, the view of memory as simply a storage or retrieval of data is changing, giving a more active and dynamic role to the process of memorizing. The use of neuroimaging technologies such as fMRI (functional magnetic resonance imaging), PET (positron emission tomography), EEG (electroencephalography), and MEG (magnetoencephalography) is allowing us to understand how the brain works, moving away from the black box of decades past, filled with unused data and information, and opening up a different perspective on the concept of memorization and, consequently, on learning. Currently, neuroscientists have identified the existence of different types of memory, either through research or by observing them in people affected by injuries or illnesses (Gluck, Mercado, & Myers, 2009). In his book, *The Brain and Learning*, Jossey-Bass states that memory is not a unitary construct; rather, the characteristics of learning are related to the ability to remember, which is not a passive event but a series of events that organize memories into a meaningful sequence. He considers memory a phenomenon that encompasses the entire brain. Furthermore, he maintains that the brain structures linked to learning mathematics differ from those linked to learning to read or to learning to play the piano. The same is true for the memory systems linked to these activities, which develop at different times. Similarly, remembering who you are or where you are from activates different memories in separate brain regions. Understanding how memory works reveals the role that experience and practice play in the learning and memorization process by modifying neural structures. On the one hand, there is a direct relationship between the number of experiences involved and the complexity of the environment with the number of structures that change in the brain; and on the other hand, practice increases the capacity to learn and memorize. It is also known that learning and memory not only affect the number of synapses, but also change the structural dynamics of the brain by modifying the supporting cells, the astrocytes, and the blood capillaries that provide nourishment to neurons. Memory is considered a “storehouse” of information from which data is retrieved when needed. Eric Kandel, Nobel laureate in Medicine in 2000, defines it as “the ability to acquire and store extremely diverse information, from trivialities of daily life to complex abstractions of geography and algebra. Thanks to this ability, we can solve problems by recalling different experiences” (Kandel, 2007). Kandel mentions that with the birth of cognitive neuroscience, about 40 years ago, it became possible to link the strategies used in psychology with biological methods for studying the brain. This allows us to biologically examine the mental processes that take place in the brain, suggesting that creative activities such as language, music, and art are functions involving specialized neural circuits in different brain regions, which are made up of nerve cells, neurons (Kandel, 2007). Taking this biological perspective on the processes involved in learning and memorization, we can say that learning gathers stimuli from the environment through different neural circuits, which then pass them on to be stored in various neural networks—memories. Memory carries out a process of neuronal “manipulation” to store information in these different neural networks, so that finally, through a process of recall, different circuits and neural networks are connected to produce a behavior or solve a problem. This biological view allows us to see a more active role for memory in this entire stage of information processing and retrieval, rather than simply as a “storage” system. It involves a series of spatiotemporal neuronal interactions between different memories to generate a response to the environment. # MEMORY IN AN EXECUTIVE ROLE One of the memories that led me to start this reflection and rethink that they have a more active role in cognitive processes and therefore in learning, is undoubtedly the executive function of working memory, which has been defined “as the center of the cognitive construct that supports general intelligence and creative thinking” (Geake, 2009). The executive function of working memory reflects, in a way, the educational field’s interest in identifying the brain’s center responsible for mentalizing or performing metacognitive functions, controlling processes related to products, planning goals, and maintaining attention on important tasks (Geake, 2009). Working memory manages information by manipulating and maintaining it to accomplish a task, and it plans and organizes goals as the situation demands. This memory undergoes continuous updating and reorganization to fulfill the proposed tasks and is also involved in unconscious processing mechanisms that allow us to find solutions to problems after a good night’s sleep. In addition to storing information in long-term memory, working memory manipulates information to guide behavior. Researchers have found evidence of executive control of working memory in many cognitive functions, including: updating memory by receiving and evaluating sensory information to transfer it to long-term memory and retrieve it from there, and deciding which memories are needed for which tasks; The establishment of goals and plans, recording goals, planning how to achieve them in advance, and setting priorities; task switching, monitoring external cues for information indicating the need to switch from one task to another; and stimulus selection and response inhibition, allowing the evaluation of a stimulus selection and the inhibition of a habitual response, shifting attention to a new alternative that responds to a specific context (Gluck, Mercado, & Myers, 2009; Geake, 2009). According to M.C. Etchepareborda, working memory is responsible for channeling the flow of information in the neural system, performing attentional functions, encoding and retaining verbal information, language acquisition, and the processing of visuospatial information. It governs memory systems, distributing attention to each task according to the demands placed on the neural system, the individual’s level of experience, and the demands of the environment. Furthermore, as a task is mastered, less attention will be needed, allowing the execution of other compatible tasks, giving working memory a more dynamic and executive role than a simple data file. Another interesting aspect is the location of the executive center for working memory. Neuroimaging studies show that the neural functions of the frontal cortex are linked to working memory performance. This strengthens the idea of an active role for memory, since the frontal cortex, on the one hand, is the region that would be best connected to perform all these tasks and, on the other hand, has all the necessary inputs and outputs to develop an executive function regarding cognitive and operational control over selective attention (Geake, 2009). Given what we’ve just seen about the executive role of memory, the question arises: can we still think that memory is limited to simply storing information? Clearly not; we would have to look at the concept of learning and memory in a different way. # LEARNING VS. MEMORIZING Let’s now look at one of the most widely used definitions of learning, that of John Anderson: “Learning is the process by which lasting changes occur in behavioral potential as a result of experience” (Andersen, 2001) (Londoño, 2008). The incorporation of experience is an aspect we can assign to learning, while in recall and behavioral change, one hardly finds a clear distinction between the role of memory and learning. L. Londoño uses the term “lasting” to differentiate between learning and memory. He argues that lasting changes over time endure in learning, while recall does not (Londoño, 2008). If we consider memory as a file storage system, this might be true, but as we have seen, the way memories interact through an executive center gives it a more active role in managing cognitive processes. According to S. Machado (Machado, et al., 2008), there is a boundary between learning and memory. Both originate in neuronal plasticity, with learning being the process by which we acquire knowledge about our surrounding environment, and memory being the individual’s ability to retain and use information in different ways and over different periods. If we also consider that the executive function of working memory is located in the frontal cortex, we can see that memory plays an active role in complex thinking skills and that we can differentiate it from the role of learning. Memory is defined as that which encodes, stores, retrieves, and manages the information necessary to solve problems or generate behaviors, while learning encompasses all the processes and strategies related to acquiring information about the environment for memory. # CONCLUSIONS For education, differentiating the roles of learning and memory would allow for the optimization of pedagogical strategies aimed at promoting better learning and memorization. These two processes are intimately related and could be situated at two different yet complementary moments in the series of neural processes through which organisms manage and process information provided by the senses to adapt to the demands of their environment. Learning plays a role related to the acquisition of stimuli and the incorporation of new experiences into memory, while memory takes on a more executive role, managing all that information to provide the best response to the environment or the best solution to a problem. As we discover how the dynamics of neural networks operate in the brain during the learning and memorization process, and how this adaptive neuroplasticity occurs to change cognitive capacity, we will be able to better define the domains of learning and memory.
