Memory is the process of encoding, storing, retaining and successively recalling information and past experiences. Memory is a part of our everyday lives. It helps us to use our past experiences as pathways for future actions. The region of the brain that deals with memory is the hippocampus which is situated in the temporal lobe of the brain region.
The first step in memory process is to get information from the environment with the help of our senses. Without them we would not be able to be able to form a memory.
Once our senses have received this information, the following process of storing memory begins:
Encoding: This stage is where all the information received is collected and converted for storage. The received information is processed in three different forms: Visual,

II. Visuospatial Loop: This stores and processes information in visual and spatial form.
Long-Term Memory
Declarative/Explicit
a. Sematic: this refers to that part of long term memory that remembers facts like the names of cities,and other factual information.
b. Episodic: this refers to that part of long term memory that relates to all the events that take place in one life.
Nondeclarative/Implicit
a. Procedural: this involves memory of how to do things (motor skills) for e.g., walking, riding a bike, etc.
b. Priming: this implicit memory involving exposure to a stimulus which later influences a response to a later stimulus.
c. Conditioning: where a neutral stimulus when paired with another stimulus repeatedly provides a learning process.
d. Nonassociative: Nonassociative learning is a perpetual change in the strength of the reaction to a stimulus because of repeated exposure to the same stimuli.
• Habituation: when there is a reduced strength in a response to a stimuli.
• Sensitization: when there is an increased strength in a response to a
= Memory is the process of storing information and experiences for possible retrieval at some point in the future. This ability to create and retrieve memories is fundamental to all aspects of cognition and in a broader sense it is essential to our ability to function properly as human beings. Our memories allow us to store information about the world so that we can understand and deal with future situations on the basis of past experience. The process of thinking and problem solving relies heavily on the use of previous experience and memory also makes it possible for us to acquire language and to communicate with others. Memory also plays a basic part in the process of perception, since we can only make sense of our perceptual input by referring to our store of previous experiences.
Cognition refers to the process required for acquiring and comprehending of knowledge, this involves the use of high-functioning parts of the brain such as memory, perception, recall and attention. As speculated by cognitive psychologists, scientists and approaches, the process of cognition is defined by an interface between our internal learning processes and sensory processes, which can be also referred to as top-down and bottoms up processing. . These processes occur consciously and unconsciously and help us as individuals to function. Memory plays a big role in cognition and is described as our ability to learn new experiences as well as recall and retain past occurrences (Webster 1992), it is required for everyday learning, thinking and recalling of information in the mind, as without memory we would be learning things anew every day, even though we carry out the same routines daily. Therefore, our experiences turn into memories and are stored in our minds, but how does this process work?
Habituation is an example of conditioning. Most behavioral modification relies on conditioning of one form or another, whether by pairing a desired result with a reward, or by discouraging an unwanted behavior by removing a reward (typically attention of one form or another). Reinforcement of conditioning is accomplished through consistent reaction to behavior either rewarding or discouraging behaviors that are desirable or undesirable. Desensitization takes this technique to its extreme by flooding the animal with the stimulus in increasing stages until it stops
Memory is an important and active system that receives information. Memory is made up of three different stages sensory memory, short term memory, and long term memory. According to the power point presentation, sensory memory refers to short storage of memory that allows an individual to process information as it occurs. Short term memory refers to memory that is only available for a limited time. It is information that is held for seconds or sometimes even minutes. Long term memory refers to memory that is stored for a long period of time and it has an unlimited capacity with the ability to hold as much information as possible. Retrieval is key and it allows individuals to have memories. Episodic memory refers to memory for events that we
Memory is a group of related mental processes that are involved in acquiring, storing, and retrieving information (Hockenberry and Hocenberry page 232). I will be addressing two specific types of memory: short-term memory and long-term memory. Short-term memory holds temporary information transferred from sensory memory or long-term memory. Sensory memory is the first stage of memory and obtains information for a brief amount of time. Short-term memory is also called active memory and is stored in the prefrontal cortex which is the most active part of the brain during an activity. Short-term memory can hold information for roughly twenty seconds, but sensory memory holds information for a shorter amount of time. We usually store things such
Furthermore this article expands upon this subcategory of memory by describing the two types of tasks involved with it: verbal-production ta...
What is memory and how its work. It is usually link with the ‘thinking of again’ or ‘recalling to the mind’ of a thing learned or memorized before. Definitions of this sort imply conscious awareness in the remembered that they are recollecting something of the past. For instance, we may remember our first day of school or some information like who is the president of the country. Basically, this is just tiny part of our capacity when we check out the full human memory capabilities.
Email, lettre, disc... The memory acts in the same way and info are supported by specific codes: sensorial codes, motor codes and symbolic codes. A special memory exists to each different info: tactual, visual, auditory and olfactory but these codes don’t have the same importance. Visual and auditory codes are the most important codes because they are the primary means of language in the memory. The auditory code is concerned with longer times than the visual one. (You remember longer a sequence of letters if you hear them than if you see them).
Classical conditioning is a technique of learning that occurs when an unconditional stimulus is paired with a conditional stimulus. The unconditional stimulus is biologically potent, the conditional stimulus is neutral (Kalat, 2011). Example of each is taste of food and sound of tuning fork respectively. After repeated pairing, the organism exhibits a conditional response to the conditional stimulus. The conditional response is similar to the unconditioned response though it is relatively impermanent and is acquired through experience (Kalat, 2011).
Memory is the tool we use to learn and think. We all use memory in our everyday lives. Memory is the mental faculty of retaining and recalling past experiences. We all reassure ourselves that our memories are accurate and precise. Many people believe that they would be able to remember anything from the event and the different features of the situation. Yet, people don’t realize the fact that the more you think about a situation the more likely the story will change. Our memories are not a camcorder or a camera. Our memory tends to be very selective and reconstructive.
The first stage is known as Encoding, which is how the memories are formed. Encoding requires selective attention to the material to be encoded (Intelegen Inc.). All the messages are registered but only the meaningful ones are put into memory. There are different types of encoding. Structural Encoding is the first; it keeps emphasis on the physical structural characteristics, also known as the shallow level. Phonemic Encoding is the second; it keeps the emphasis on the sounds of words, the intermediate level. ...
Long-term memory is how humans process in the present, recall information from the past, or think about the future. Without long-term memory one cannot remember past memories, today, or what we may plan to do in the future. On top of that, there is no learning without long-term memory and the progress that we see today in our fast pace driven world would not exist. This is why the study and understanding of long-term memory is important for further knowledge of human nature. The long-term memory itself takes in many different forms of information including images, sounds, and meaning. The orientation of memory encompasses three important stages and the first is encoding. Encoding takes places in different locations inside the brain and this
Learning is defined as a “process of change that occurs as a result of an individual’s experience” (Mazure, 2006). Researchers assume that the process of learning follows certain general principles, which were developed, into the general process learning theories. These include operant conditioning and classical conditioning which has been put forward by leading psychologists like Pavlov, B.F.Skinner and Thorndike. However, in learning, operant and classical conditoning are opposed by biological constraints that state that there are limitations to the theories. Some of these biological constraints on learning will be discussed below.
Learning to tie shoes and ride a bike requires the encoding, storing, and retrieving of past observations of the procedure. With a lot of practice, children master these skills so well that they are able to remember them the rest of their lives. Memory is the storing of information over time. It is one of the most important concepts in learning; if things are not remembered, no learning can take place. As a process, memory refers to the "dynamic mechanism associated with the retention and retrieval of information about past experiences" (Sternberg 260). We use our memory about the past to help us understand the present. The study or memory in psychology is used in different ways, as well as there are many different ways to study how memory works in humans. In psychology there are many tasks used to measure memory, and different types of memory storages that human's use, such as sensory storing, or short term storing. There are also a lot of techniques that humans use to improve their memory, which they can use to learn, such as mnemonic devices. All these things can be classified as important issues in the study of human memory and ways of learning.
This is selective reinforcement. Pavlov and his dogs were and excellent example of operant conditioning. Pavlov rang a bell when it was time for the dogs to eat; eventually the dogs associated the bell with food. Each time the bell rang the dogs salivated. On the other hand, N.Chomsky who was a nativist argued that children are born with a language acquisition device (LAD).
