many of our failures of memory are failures of ______

episodic

memories lose their _____ character over time, which is known as the semanticization of remote memories

long term potentiation

one of the outcomes of structural changes at the synapse is a strengthening of synaptic transmission. This strengthening results in a phenomenon called _____ _____ ____- enhanced firing of neurons after repeated stimulation

retrieval cue

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. This gradual decrease in amnesia corresponds, according to the _______ model, to the changes in connections between the hippocampus and cortical areas.

according to the standard model of consolidation, the hippocampus is _____ active when memories are first formed and initially recalled but becomes _____ involved as memories are consolidated

levels of processing

an early idea linking the type of encoding to retrieval, proposed by Craik and Lockhart, is called ___________ ___ _______ theory. According to this, memory depends on the depth of processing an item receives

As time passes, connections are formed between the cortical areas, and the connections between the ______ and cortex are weakened and eventually vanish

generation

the ______ effect explains that generating material yourself, rather than passively receiving it, enhances learning and retention

encoding specificity

there was an experiment where students studied in either a quiet or noisy location and then took the test in either a quiet or noisy room.

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. Later, the first word of each pair is presented, and the subject's task is to remember the word it was paired with. 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.

Subjects who saw the pic before they read the passage remember _____ as much from the passage as subjects who didn't see the pic or saw it after reading. They key here is ________.

episodic, multiple trace

Gilboa did an experiment where he elicited recent and remote episodic memories by showing subjects pics of themselves taken at various times ranging from recent to when they were only 5 yrs old. The results of this experiment showed that the hippocampus was activated during both retrieval of recent and remote _______ memories. This supports the _____ ______ model of consolidation

transfer appropriate processing, rhyming

_____ _____ ____ is the idea that retrieval is better if the same cognitive tasks are involved during both encoding and retrieval. This seems obvious and i think the experiments showing this are stupid. The experiment for this is basically just having people study one thing and if that's what the test is on they do better. duh. Subjects who did a _____ based encoding task did better on the rhyming test than subjects who did a meaning based encoding task.

survival

linking words to ______ created memory that was actually better than the elaborate tasks (like forming visual images, self reference effect, generation effect)
