Alzheimer's Disease (AD)
progressive mental deterioration by severe memory loss
anterograde amnesia
inability to form new memories after a brain injury; forward-acting amnesia
consolidation
process by which neural changes associated with recent learning become durable and stable
Distributed practice
practice sessions are interspersed with rest periods
long-term potentiation (LTP)
long-lasting increase in neural excitability, which may be a biological mechanism for learning and memory
massed practice
time spent learning is grouped into long, unbroken intervals (cramming)
misinformation effect
distortion of a memory by misleading past-event information
Mnemonic Device
memory-improvement technique based on encoding items in a special way
proactive interference
old information interferes with remembering new information; forward-acting interference
recognition
retrieving a memory using a specific cue
relearning
learning material a second time , which takes less time than original learning (savings method)
retrieval
recovering information from memory storage
retrieval cues
cue or prompt that helps stimulate recall or retrieval of a stored piece of information from long-term memory
retroactive interference
new information interferes with remembering old information; backward-acting interference
retrograde amnesia
loss of memory for events before a brain injury; backward-acting amnesia
Semantic memory
Subsystem of explicit/declarative memory that stores general knowledge ; a mental encyclopedia or dictionary
sensory memory
First memory stage that holds sensory information; relatively large capacity, but duration is only a few seconds
serial-position effect
Information at the beginning and end of a list is remembered better than material in the middle
short-term memory (STM)
Second memory stage that temporarily stores sensory information and decides whether to send it on to long-term memory (LTM); capacity is limited to five to nine items and duration is about 30 seconds
sleeper effect
information from an unreliable source, which was initially discounted , later gains credibility because the source is forgotten
source amnesia
forgetting the true source of a memory (source confusion or source misattribution)
storage
retaining information over time
tip-of-the-tongue phenomenon
feeling that specific information is stored in long-term memory but of being temporarily unable to retrieve it
