The Biological and Psychological Basis of Learning and Memory

Memory is not located in just one spot of the brain, but it is a brain wide process, in which

The brain can be considered the most complex organ in the body and the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists have identified areas within it that perform specific functions. This makes the brain interconnected by three different layers: the central core, the limbic system, and the cerebral cortex. All of which contain structures that regulate everyday life and psychological function.

The part of the brain that is in charge of memory is called the hippocampus, which is part of the cerebral cortex. The cerebral cortex is in charge of thinking, problem solving, and many different kinds of language skills. People that have a problem with their hippocampus can have trouble remembering new details they have taken in. There are also many different parts of the hippocampus that apply directly to the memory. These parts include short-term memory, long-term memory, sensory memory, and the constructive processes. Short-term memory is the information that stays in your brain only when you are thinking about it, about 20 to 30 seconds. After this, it is most likely forgotten. Long-term memory is when your hippocampus keeps track of facts you learn, ideas you have, and experiences. Even when people stop thinking about these things, the memory can last a lifetime. Another part of the hippocampus, sensory memory, remembers information only for one or two seconds. The brain creates a mental image that disappears when you stop directly thinking about a particular thing. The last part of the hippocampus is the constructive processes. Constructive processes are memories that your brain makes up in order to make sense of a detail in which you only remember some of the details. The few details that the brain remembers are combined with other small details that your brain adds in order for it to

Research has shown that there is “greater activation in the left inferior frontal and medial temporal lobes” (Stanford, 2006, p. 208) during the encoding of words which were later remembered as compared to those which were forgotten. The sensations perceived by sensory nerves are decoded in the hippocampus of the brain into a single experience (Mastin, 2010). The hippocampus analyses new information and compares and asssociates it with previously stored memory (Mastin, 2010). Human memory is associative in that new information can be remembered better if it can be associated to previously acquired, firmly consolidated information (Mastin, 2010). The various pieces of information are then stored in different parts of the brain (Mastin, 2010). Though the exact method by which this information is later identified and recalled has yet to be discovered, it is understood that ultra-short term sensory memory is converted into short term memory which can then later be consolidated into long term memory (Mastin, 2010).

1) Memory is the act of reviewing or processing of what has been studied. We use memory to learn and think in our everyday lives. Memory is a personal library in our brain for us to look back at information we encounter in our lives. While doing research on this paper I stumbled upon a lot of informations about memory and tips and trick to improve our memory. In chapter 7 of Karen Huffman and Katherine Dowdell's textbook, I learned amazing new bits knowledge into how we recall information and why we forget. Memory is broken up into three parts. You have encoding, storage, retrieval. Encoding is the introductory learning data. Storage is the maintenance of encoded data over time. Retrieval is the ability to get to the data when you need it. All three of memory stages figures out if something is recollected or forgotten. Students will likely not remember

Memory in the human brain is a complex process which is easier understood by the use of theoretical constructs. Memories begin as sensory stimuli which become sensory memory which only last about one second, from there it moves into working memory which lasts for about twenty to thirty seconds and is used to process information. Within working memory there are a few separate processes, the central executive which directs attention, the episodic buffer which is a secondary storage lasting ten to twenty seconds, this area communicates with long term memory as well as the central executive. The visuospatial sketchpad which is used to visualise visual and spacial

The different parts of the brain are responsible for sending out signals throughout our body which then helps accomplish daily tasks. For example, the frontal lobe is responsible for cognition and memory. This area also allows the ability to concentrate, make a judgment, and emotional traits. The temporal lobe is responsible for hearing. This area also contains the Hippocampus, where long-term memory is formed. The brain stem is the alarm system and warns the brain of danger. The cerebellum is responsible for coordination and cognitive function such as language. The occipital lobe is responsible visual processing which is known as the visual cortex. Lastly, the parietal lobe is responsible for processing information from some of the senses. As you can see the brain has an immense amount of responsibility to take in order for us to live. Due to aging our brain cells begin to start working improperly. Alzheimer’s impairs the brain cells from each lobe from functioning properly, which can cause brain damage, cognitive inability, and/or

Some scientists believe that parts of long term memory are permanent while others will eventually weaken over time. (3) Long term memory can be divided into three sections: procedural memory, declarative memory, and remote memory. Procedural memory includes motor skills such as learning how to ride a bike or how to drive a car. "Such memories are slow to acquire but more resistant to change or loss." (4) Declarative memory is used to remember facts, such as names, dates and places. It is easy to learn but also easy to lose. Finally there is episodic memory, which is the record of events that a person stores throughout his or her experience. Recent studies show that these events, as soon as they occur, are sent to a temporary part of the brain called the hippocampus, and that over time they are moved to the neocortex for permanent storage. (5).

Learning is a very important aspect of humans and creatures alike. Not only is it essential to the survival and adaption into this world but it also defines who we are as individuals (Schiller et al, 2010; Tronson & Taylor, 2007). Memories from past experiences shape the people that we are today. A crucial element to learning is memory, without it we would not be able to retain information. The process of memory is very distinct and consists of several different stages: acquisition of memory, consolidation, retrieval and then either reconsolidation or extinction (Debiec & Ledoux, 2004; Diergaarde, Schoffelmeer & De Vries, 2008). As memory is such a critical aspect of learning, it is no wonder that its distinct process has become the topic of much research in the neurobiological universe (Hupbach et al, 2007; Nader & Hardt, 2009).

Learning is the process of gaining knowledge or skills through study, experience or teaching. It is a process that depends on experience and leads to long-term changes in the possible behaviour of an individual in a given situation, in order to achieve a goal.

The two concepts that I resonated with are Memory and the Psychodynamic theory. Starting with the Psychodynamic theory is an approach to psychology that studies the psychological forces underlying human behavior, feelings, and emotions, and how they may relate to early childhood experience. This theory is most closely associated with the work of Sigmund Freud, and with psychoanalysis, a type of psychotherapy that attempts to explore the patient’s unconscious thoughts and emotions so that the person is better able to understand him or herself. The second one is Memory; understanding how memory works will help you improves your memory. Which is an essential key to attaining knowledge. Memory is one of the important cognitive processes. Memory involves remembering and forgetting. I chose the two concepts because throughout the class they stood out to the most. Understanding the conscious, subconscious mind and also memory. I’m interested in understanding the human behavior.

If we look at the brain as if it were a central computer that controlled all of the bodily functions, then we would refer to the central nervous system and the network that relays messages to and from the

Memory is defined as "the persistence of learning over time through the storage and retrieval of information." Our memory can be compared to a computer's information processing system. To remember an event we need to get information into our brain which is encoding, store the information and then be able to retrieve it. The three-stage processing model of Richard Atkinson and Richard Shiffrin suggests that we record information that we want to remember first as a fleeting sensory memory and then it is processed into a short term memory bin where we encode it ( pay attention to encode important or novel stimuli) for long-term memory and later retrieval. The premise for the three step process is that we are unable to focus on too much

Memory makes us. It is, to an extent, a collection of unique and personal experiences that we, as individuals, have amassed over our lifetime. It is what connects us to our past and what shapes our present and the future. If we are unable remember the what, when, where, and who of our everyday lives, our level of functioning would be greatly impacted. Memory is defined as or recognized as the “sum or total of what we remember.” Memory provides us the ability to learn and adjust to or from prior experiences. In addition, memory or our ability to remember plays an integral role in the building and sustaining of relationships. Additionally, memory is also a process; it is how we internalize and store our external environment and experiences. It entails the capacity to remember past experiences, and the process of recalling previous experiences, information, impressions, habits and skills to awareness. It is the storage of materials learned and/or retained from our experiences. This fact is demonstrated by the modification, adjustment and/or adaptation of structure or behavior. Furthermore, we as individuals, envision thoughts and ideas of the present through short-term memory, or in our working memory, we warehouse past experiences and learned values in long-term memory, also referred to as episodic or semantic memory. Most importantly, memory is malleable and it is intimately linked to our sense of identity and where we believe we belong in the world.

The brain is dividing into several sections, including the cerebellum, the frontal lobe, and the temporal lobe, among others. The temporal lobe exists in two parts, one on each side of the brain close to the ears. It is largely responsible for the memory system (2). On the medial surface of the temporal lobe there are three important structure that are essential for human functioning. These structures are named, in order from rostral to caudal, the olfactory cortex, the amygdala, and the hippocampus. Together these three structures are referred to as the "limbic system" (1). Their functions became understood after studying how the brain functions upon loss of each structure. For example, in 1953, a patient suffering from epilepsy underwent surgery which removed most of his medial temporal lobe (1). After the surgery, the patient was able to remember who he was and was able to carry out coherent, intelligent conversations. However, if the person with whom he was talking left the room, he would have no
