Practice Question Flashcards
What are encoding, storage, and retrieval?
encoding- getting information into memory
storage- retaining memory for future use
retrieval- recovering/recapturing memory when we need them
What are the three memory stores suggested by the information processing model?
Sensory memory- holds sensory information for quick snapshot. 1/2 sec
Working memory- holds info temporarily for analysis. up to 30 sec (7 plus minus 2)
Long term memory- relatively permanent storage. relatively unlimited capacity
How does increasing attention affect autonomic and effortful processing?
allows for more efficient and more effective effortful processing
no big impact on autonomic processing
Why is it more effective to study all term long, rather than in one massive session right before a final exam?
This is due to the spacing effect.
Information passes to our long term memory best when the rehearsal is spread overtime.
Which type of encoding would most people use to remember someone’s face? Which type to remember someone’s name?
visual for face (holding images)
phonological for name (holding sounds)
What is chunking, and why would you want to use it?
grouping letters or words together
so you can encode and store more information in working memory at a time
What kind of information is stored in semantic memory and episodic memory? are semantic and episodic memories implicit or explicit?
semantic- general facts
episodic- details about a certain event or personal experience
they are explicit memories (conscious recall)
If researchers show people several pictures of small rodents, then find that a lot of people include hamsters and mice when asked to name animals that make good pets, what has happened? Why did it happen?
priming- activation of one piece of information leads to activation of another piece, which leads to retrieval of specific memory.
Why do many educators believe it is helpful to take an exam in the same room where you learned the material?
context of the event can also serve as retrieval cues.
How do strong emotions affect our memory processes?
strong emotions enhance memories by leading to increased rehearsal, elaboration, and organization of an event.
special emotional memory mechanisms create flashbulb memoriesH
How does the decay theory explain forgetting?
shows that memories fade away on their own because they are neglected or not used for a long period of time
What is repression?
process in which we unconsciously prevent some traumatic events from entering our awareness, so that we do not have to experience the anxiety that the memories would bring
The saying “Elementary, my dear Watson” did not appear in any of Sir Arthur Conan Doyle’s work, yet millions of fans vividly remember reading these words. What processes can explain this manufactured memory?
Which parts of the brain are most active in memory? How are these parts related to neurotransmitters involved in memory?
Hippocampus convert explicit memories to long term
Neocortex: prefrontal cortex for working memory
where the neurons that display LTP reside.
Glutamate is key neurotransmitter in memories
What is a neural network and how might long term potentiation contribute to its formation?
LTP- repeated stimulation of certain nerve cells in brain can greatly increase the likelihood that the cells will respond strongly to future stimulations
Neural network is a group of connected neurons.
LTP help make these connections because the neurons now have stronger connection and more likely to stimulate each other
Why are toddlers able to effectively remember faces, places, objects, and certain skills, but not able to remember the events of their lives very well?
Brain circuits responsible for storing memories of events seem to develop more slowly than brain circuits responsible for storing info about language, motor skills, and simple association
Why do memories of elderly people tend to decline and what techniques seem to help prevent or slow down memory problems?
Brain parts like hippocampus start to shrink.
Brain puzzles,
Exercise can help slow down/prevent deficiencies and impairment of memories
Compare and contrast retrograde and anterograde amnesia. What are the causes of both?
Retrograde- forgot old stuff but can make new memories
Anterograde- remember old stuff but can’t make new memories
caused by head injuries
What changes happen in the brains of people with Alzheimer’s?
Their brains have more neurofibrillary tangles and senile plaques than normal. Signals a destructive process in the brain
How do dissociative disorders differ from organic memory disorders?
Organic memory disorders have clear organic causes like head injuries.
Dissociative disorders have no clear physical cause
What are the three components of attitudes, according to the ABC model?
Affective- how we feel
Behavioral- how we act
Cognitive- what we believe
How do cognitive dissonance theory and self-perception theory differ in their explanation of attitude change?
Cognitive Dissonance Theory- people will try to alter behavior to reduce cognitive dissonance
Self-Perception Theory- when people are uncertain of their attitudes, they infer what the attitudes are by observing their own behavior
In CD, the attitudes are clear and important to individual but in SP theory, the attitudes are ambiguous
Why do people sometimes misrepresent their attitudes?
People often state attitudes that are socially desirable rather than accurate.
Sometimes people are unaware of their attitudes. Can figure out these implicit attitudes through IAT
How does social identity theory explain prejudice?
Social Identity Theory:
prejudice emerges through 3 processes
- Social categorization: people affiliates with a group to learn how to act in the world
- Social Identity: person forms identity within a group
- Social Comparison: group members thinks their group is better.
