Memory
the mental process of acquiring, storing, and retrieving information, essentially the ability to retain and recall past experiences and knowledge through the stages of encoding, storage, and retrieval.
Semantic memory
a type of long-term memory that stores general knowledge about the world, including facts, concepts, and the meaning of words, essentially representing a person’s accumulated knowledge about the world, distinct from personal experiences stored in episodic memory; it is considered a form of explicit memory, meaning it can be consciously recalled
Example: Knowing that the capital of France is Paris.
prospective memory
the cognitive ability to remember to perform a planned action or intention at a specific time in the future, essentially meaning “remembering to remember” to do something later on; like remembering to take medication at a certain time or pick up groceries on the way home from work.
working memory
a cognitive system that temporarily holds a limited amount of information readily available for immediate use during mental tasks like reasoning, problem solving, and comprehension, essentially allowing for the manipulation of information while actively processing it
visuospatial sketchpad
a component of working memory responsible for temporarily storing and manipulating visual and spatial information, like the layout of a room, the color of an object, or the mental image of a picture, allowing us to visualize and interact with these images in our minds.
iconic memory
a very brief sensory memory that stores visual information for a fraction of a second after an image is seen, essentially allowing us to perceive a complete visual scene momentarily before it fades away; it’s considered a part of sensory memory, specifically related to sight.
long term memory
the storage system in the brain that holds information for extended periods, potentially a lifetime, including facts, experiences, and skills, allowing for retrieval of memories from a long time ago; essentially, it’s where information is transferred from short-term memory to be stored indefinitely, with seemingly unlimited capacity.
encoding
the initial process of transforming sensory information into a format that can be stored in memory, essentially the act of actively putting new information into memory by processing it and preparing it for storage; it is the first stage of the memory process, where information is converted into neural codes that can be retained by the brain
levels of processing model
Structural level: Processing based on the visual appearance of the information (e.g., remembering a word based on how it looks).
Phonemic level: Processing based on the sound of the information (e.g., remembering a word based on how it sounds).
Semantic level: Processing based on the meaning of the information (e.g., understanding the concept behind a word).
semantic processing
the cognitive process of encoding information based on its meaning, where you understand and relate new information to existing knowledge by focusing on the concept’s deeper meaning rather than just its surface characteristics; it’s considered a type of “deep processing” within memory encoding.
explicit memory
a type of long-term memory that involves the conscious and intentional recollection of factual information or personal experiences, essentially memories that can be verbally declared and retrieved with conscious effort; it is also known as “declarative memory” and includes both semantic (general knowledge) and episodic (personal events) memories
implicit memory
a type of long-term memory where information is unconsciously retained and retrieved, meaning you are not aware of remembering it; it is often associated with automatic skills like riding a bike or typing on a keyboard, where the knowledge is acquired through repeated practice without conscious effort.
long term potential
a neurological process where repeated stimulation of a synapse between neurons leads to a lasting strengthening of that connection, essentially forming the cellular basis for learning and memory formation within the brain; it signifies the ability of synapses to become more efficient at transmitting signals over time, allowing for better recall of information.
central executive
a key component of Baddeley’s working memory model, essentially acting as a control system that directs attention, manages information flow between different parts of working memory, and coordinates cognitive processes like decision-making, planning, and task switching; essentially the “boss” of the working memory system that decides where to allocate cognitive resources.
multi store model
a theory of memory that proposes information flows through three distinct stages: the sensory register, short-term memory (STM), and long-term memory (LTM), with each stage having different capacities and durations for storing information; essentially describing how information is received, temporarily held, and then potentially transferred to long-term storage for later recall.
Three memory stores:
Sensory register: Briefly holds sensory information from all senses, lasting only milliseconds.
Short-term memory (STM): Temporarily stores a limited amount of information for a short period (around 30 seconds).
Long-term memory (LTM): Stores information for extended periods, potentially a lifetime.
How information moves through the model:
Attention: Information from the sensory register that is attended to moves to the STM.
Rehearsal: To transfer information from STM to LTM, it must be actively rehearsed.
Retrieval: When needed, information is retrieved from LTM back into STM for conscious access.
echoic memory
the brief sensory memory that stores auditory information, essentially acting like a temporary “echo” of a sound, allowing us to process and understand spoken words even if they are heard only once; it’s a type of sensory memory specifically related to hearing.
automatic processing
the unconscious encoding of information, where details like time, space, and frequency are processed without deliberate effort, often happening with well-learned or familiar stimuli, essentially “autopilot” cognitive function where information is absorbed without active thinking.
storage
the process of retaining encoded information over time, essentially meaning the act of holding information in the brain for later retrieval; it is one of the key stages of memory alongside encoding and retrieval, where information is kept within the memory system after it has been processed and encoded.
structural processing
a shallow level of information processing where a person primarily focuses on the physical characteristics or appearance of a stimulus, like the shape or font of a word, rather than its meaning or sound, essentially encoding information based on its visual structure.
episodic memory
a type of long-term memory that stores personal experiences and specific events, including details about the time and place where they occurred, essentially remembering “episodes” from one’s life, like recalling a specific birthday party or the first day of school; it is considered a form of explicit memory alongside semantic memory
procedural memory
a type of implicit memory that stores information about how to perform actions or skills, essentially the memory of “how to do something,” like riding a bike, typing on a keyboard, or tying your shoes, which are automatically retrieved and used without conscious awareness or effort; it is learned through repetition and practice.
working memory model
a theoretical framework that explains how the working memory system functions. It consists of three components: the phonological loop, the visuospatial sketchpad, and the central executive.
Working memory is a cognitive system with limited capacity that can hold information temporarily while processing or manipulating it simultaneously.
phonological loop
a component of working memory responsible for temporarily storing and manipulating auditory information, particularly verbal language, essentially acting like an “inner ear” that allows you to rehearse sounds and words mentally to remember them, like when trying to recall a phone number or follow spoken instructions.
Key points about the phonological loop:
Function: It processes and holds verbal and auditory information.
Components: The phonological loop is often described as having two parts:
Phonological store: A passive storage area for sounds.
Articulatory process: An active rehearsal mechanism, essentially your “inner voice” that repeats sounds to keep them in memory.
sensory memory
the initial stage of memory that briefly holds an exact copy of incoming sensory information from all five senses (sight, hearing, touch, taste, smell) for a very short period of time, allowing for further processing before the information is either discarded or transferred to short-term memory; essentially, it’s the ability to retain sensory impressions just long enough to recognize them after the original stimulus has ended.
