Ch. 7 - Human Memory Flashcards
Amnesia
A significant memory loss that is too extensive to be due to normal forgetting. See also Anterograde amnesia, Retrograde amnesia.
Anterograde amnesia
Loss of memories for events that occur after a head injury.
Attention
Focusing awareness on a narrowed range of stimuli or events.
Chunk
A group of familiar stimuli stored as a single unit.
Conceptual hierarchy
A multilevel classification system based on common properties among items.
Connectionist models
Models of memory that assume cognitive processes depend on patterns of activation in highly interconnected computational networks that resemble neural networks. See parallel distributed processing (PDP) models.
Consolidation
A hypothetical process involving the gradual conversion of information into durable memory codes stored in long-term memory.
Declarative memory system
Memory for factual information.
Destination memory
Recalling to whom one has told what.
Elaboration
Linking a stimulus to other information at the time of encoding.
Encoding
Forming a memory code.
Encoding specificity principle
The idea that the value of a retrieval cue depends on how well it corresponds to the memory code.
Episodic memory system
Chronological, or temporally dated, recollections of personal experiences.
Flashbulb memories
Unusually vivid and detailed recollections of momentous events.
Forgetting curve
A graph showing retention and forgetting over time.
Hindsight bias
The tendency to mold one’s interpretation of the past to fit how events actually turned out.
Link method
Forming a mental image of items to be remembered in a way that links them together.
Long-term memory (LTM)
An unlimited capacity store that can hold information over lengthy periods of time.
Long-term potentiation (LTP)
A long-lasting increase in neural excitability in synapses along a specific neural pathway.
Method of loci
A mnemonic device that involves taking an imaginary walk along a familiar path where images of items to be remembered are associated with certain locations.
