System of Memory
System of Memory
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their ...
Encoding
Encoding
Encoding is the process by which information gets input into the memory system. It involves the brain labeling sensory information received from the ...

Sensory Memory
Sensory memory stores information from the environment, such as sights, sounds, and tastes, in its original sensory form, and it lasts only for a couple ...
Working Memory
Working Memory
Working memory is a dynamic system that combines short-term memory and attention. For example, solving mathematical problems requires temporary retention ...
Chunking and Rehearsal in Sensory Memory
Chunking and Rehearsal in Sensory Memory
Chunking and rehearsal are two effective techniques to enhance short-term memory. Chunking involves grouping information into higher-order units that can ...
Storage
Storage
Storage in memory involves the process of keeping information for future use. Schemas are mental frameworks that help to organize and interpret ...
Long-Term Memory
Long-Term Memory
Long-term memory, or LTM, stores vast amounts of information for extended periods. LTM is categorized into two types: explicit memory and implicit ...
Explicit Memories
Explicit Memories
Explicit memories, also known as declarative memories, involve conscious recollection of events and facts. Explicit memory can be categorized into two ...
Implicit Memories
Implicit Memories
Playing tennis, snowboarding, and texting rely on implicit or non-declarative memory, which includes long-term memories that influence behavior through ...
Serial Position Effect
Serial Position Effect
The serial position effect illustrates that individuals tend to remember the first and last items in a list better than those in the middle. For instance, ...

Eyewitness memory refers to a person's recollection of events they have directly witnessed. It is often used as evidence in legal settings. For ...
Role of Amygdala in Memory
Role of Amygdala in Memory
The amygdala, a small, almond-shaped structure within the brain, plays a crucial role in processing memories of emotionally charged events associated with ...
Role of Hippocampus in Memory
Role of Hippocampus in Memory
The hippocampus is a small, seahorse-shaped structure in the brain that plays a crucial role in memory processing, particularly in forming and retrieving ...
Role of Cerebellum and Prefrontal Cortex in Memory
Role of Cerebellum and Prefrontal Cortex in Memory
The cerebellum is a fist-sized part of the brain located at the back of the head. It is vital for procedural memory, which enables learning motor tasks ...
Role of Neurotransmitters in Memory
Role of Neurotransmitters in Memory
Neurotransmitters are chemical messengers that play a crucial role in transmitting signals across synapses in the brain. Neurotransmitter-mediated ...
Forgetting
Forgetting
Forgetting is a process in which memories become inaccessible or lost over time. Hermann Ebbinghaus pioneered studies on forgetting and developed the ...
Interference and Decay
Interference and Decay
Interference and decay are two key processes that contribute to forgetting. Interference occurs when competing memories impair the ability to retrieve ...
Tip-of-the-Tongue Phenomenon
Tip-of-the-Tongue Phenomenon
The Tip-of-the-Tongue phenomenon is a cognitive state in which a person temporarily cannot recall a word or piece of information despite feeling that they ...
Chunking
Chunking
Chunking is a cognitive strategy that enhances short-term memory by organizing information into smaller, manageable units, or "chunks." This ...
Elaborative Rehearsals
Elaborative Rehearsals
Elaborative rehearsal is a cognitive strategy that aids in transferring information from short-term to long-term memory by linking new information with ...
Mnemonic Devices
Mnemonic Devices
Mnemonic devices are memory aids that enhance our memory by associating new information with familiar or organized patterns. Some mnemonic devices are ...
False Memories
False Memories
False memories are a cognitive phenomenon in which individuals recall events that never occurred or are distorted versions of actual events. Research into ...
