Introduction
-
Memory phenomena refer to observable or measurable events related to memory processes such as Encoding, Storage, Retrieval, or Forgetting.
-
Key memory phenomena include recency, contiguity, similarity, primacy, and repetition.
-
Memory is divided into different types: Sensory memory, Short-term memory, Working memory, and Long-term memory.
-
Long-term memory can be further categorized into implicit (unconscious) and explicit (conscious) memory.
-
Neuroscience of memory involves various brain regions like the Hippocampus, Neocortex, and Amygdala for different types of memories.
Types of Memory [1]
-
Sensory Memory: The shortest-term element of memory, it is the ability to retain impressions of sensory information after the original stimuli have ended.
-
Short-Term Memory: Also known as primary or active memory, it holds a small amount of information in an active, readily available state for a short period.
-
Working Memory: A form of short-term memory that involves the manipulation and processing of information.
-
Long-Term Memory: The continuous storage of information, which is divided into explicit (conscious) and implicit (unconscious) memory.
-
Explicit memory: Includes episodic memory (events) and semantic memory (facts).
-
Implicit memory: Includes procedural memory (skills) and emotional conditioning.
Laws of Memory [2]
-
Recency: The tendency to remember the most recently presented information best.
-
Contiguity: The tendency to remember items that are close together in time or space.
-
Similarity: The tendency to remember items that are similar to each other.
-
Primacy: The tendency to remember the first items in a sequence better than the middle items.
-
Repetition: The tendency to remember information that is repeated.
Neuroscience of Memory [3]
-
Hippocampus: Critical for the formation of new explicit memories.
-
Neocortex: Involved in the storage of long-term memories and the processing of sensory information.
-
Amygdala: Plays a key role in the processing of emotions and the formation of emotional memories.
-
Fronto-Parietal Regions: Activated during working memory tasks.
-
Neural Mechanisms: Different types of memories are stored across various interconnected brain regions.
Mechanisms of Forgetting [2]
-
Interference: New information can interfere with the retrieval of old information (retroactive interference) and vice versa (proactive interference).
-
Decay: Memory traces weaken over time if they are not accessed.
-
Contextual Change: Changes in the context in which a memory was formed can make it harder to retrieve.
-
Inhibition: Repeated retrieval of similar memories can inhibit the recall of other memories.
-
Rehearsal: Repeatedly thinking about or rehearsing a memory can help to maintain it over time.
Contextual Effects on Memory [2]
-
Context-Dependent Memory: Memory is better when the context at retrieval matches the context at encoding.
-
Mood-Dependent Memory: Memory is better when a person's mood at retrieval matches their mood at encoding.
-
State-Dependent Memory: Memory is better when a person's physiological state at retrieval matches their state at encoding.
-
Environmental Context: Physical surroundings can influence memory retrieval.
-
Semantic Context: The meaning of words and concepts can influence memory retrieval.
