retrieval
many of our failures of memory are failures of ______
episodic

remembering words in a particular category may serve as a _______ ____- a word or other stimulus that helps a person remember info stored in memory
synaptic
______ consolidation takes place over minutes or hours and involves structural changes at synapses.
systems
______ consolidation takes place over months or even years and involves the gradual reorganization of neural circuits within the brain.
consolidation
______ is the process that transforms new memories from a fragile state into a more permanent state

remember, know
______ responses indicate episodic memory and ______ responses indicate semantic memory. (fill in blanks w/ either remember or know)
retrieval cues
_______ _____ are words or other stimuli that help us remember info stored in our memory. (like how the word apple might help you remember grape)
anterograde
_______ amnesia is amnesia for events that occur after an injury (the inability to form new memories)
encoding, retrieval
_______ is the process of acquiring info and transferring it into LTM. _______ is transferring info from LTM in WM
deep
_______ processing involves close attention, focusing on an items meaning, and relating it to something else.
shallow
_______ processing involves little attention to meaning, as when a phone number is treated over and over or attention is focused on a word's physical features such as whether it is printed in lowercase or capital letters
levels of processing
_________ ____ ______ states that memory depends on how info is encoded or programmed into the mind.
graded, standard
a characteristic of retrograde amnesia is ____ amnesia- the amnesia tends to be most severe for events the happened just before the injury and to become less severe for earlier events.

paired associate, twice
Bower and Winzenz decided to test visual memory. They used a procedure called ______ ______ learning, where a list of word pairs is presented.

Subjects who created images remembered more than ____ as many words as the subjects who had just repeated the word pairs
twice, organization
Bransford and Johnson illustrated the effect where preventing organization from happening reduces the ability to remember.
