Psychology Week 6 - Memory
short-term memory (STM)
(also, working memory) holds about seven bits of information before it is forgotten or stored, as well as information that has been retrieved and is being used
Short-term memory storage lasts
15-30 seconds
According to the Atkinson-Shiffrin model, name and describe the three stages of memory.
According to the Atkinson-Shiffrin model, memory is processed in three stages. The first is sensory memory; this is very brief: 1-2 seconds. Anything not attended to is ignored. The stimuli we pay attention to then move into our short-term memory. Short-term memory can hold approximately 7 bits of information for around 20 seconds. Information here is either forgotten, or it is encoded into long-term memory through the process of rehearsal. Long-term memory is the permanent storage of information—its capacity is basically unlimited.
The ________ says that memories are processed the same way that a computer processes information.
Atkinson-Shiffrin model. According to the A-S model, memories are processed through sensory, short-term, and long-term memory.
Who developed the idea that short-term memories get "filed away" in three different areas of the brain: a visuo-spatial area, a phonological loop for auditory memories, and an episodic buffer for multi-modal memories with storylines?
Baddeley and Hitch
What might happen to your memory system if you sustained damage to your hippocampus?
Because your hippocampus seems to be more of a processing area for your explicit memories, injury to this area could leave you unable to process new declarative (explicit) memories; however, even with this loss, you would be able to create implicit memories (procedural memory, motor learning and classical conditioning).
Compare and contrast implicit and explicit memory.
Both are types of long-term memory. Explicit memories are memories we consciously try to remember and recall. Explicit memory is also called declarative memory and is subdivided into episodic memory (life events) and semantic memory (words, ideas, and concepts). Implicit memories are memories that are not part of our consciousness; they are memories formed from behaviors. Implicit memory is also called non-declarative memory and includes procedural memory as well as things learned through classical conditioning.
Episodic memories and semantic memories are both examples of ________ memory.
Explicit
____________ memories are passive memories that we do not have to work to remember.
Implicit
Compare and contrast the two processes we use to encode information.
Information is encoded through automatic or effortful processing. Automatic processing refers to all information that enters long-term memory without conscious effort. This includes things such as time, space, and frequency—for example, your ability to remember what you ate for breakfast today or the fact that you remember that you ran into your best friend in the supermarket twice this week. Effortful processing refers to encoding information through conscious attention and effort. Material that you study for a test requires effortful processing.
___________ and ___________ are two factors that affect short-term memory retention.
Memory trace decay; interference
In order for a memory to go into storage, it has to pass through three distinct stages known as
Sensory Memory, Short-Term Memory, and Long-Term Memory
What is the self-reference effect, and how can it help you study more effectively?
The self-reference effect is the tendency an individual to have better memory for information that relates to oneself than information that is not personally relevant. You can use the self-reference effect to relate the material to something you have already learned for another class, or think how you can apply the concepts to your life. When you do this, you are building a web of retrieval cues that will help you access the material when you want to remember it.
Compare and contrast the two types of amnesia.
There are two types of amnesia: retrograde and anterograde. Both involve the loss of long-term memory that occurs as the result of disease, physical trauma, or psychological trauma. With anterograde amnesia, you cannot remember new information; however, you can remember information and events that happened prior to your injury. Retrograde amnesia is the exact opposite: you experience loss of memory for events that occurred before the trauma.
Compare and contrast the two types of interference.
There are two types of interference: retroactive and proactive. Both are types of forgetting caused by a failure to retrieve information. With retroactive interference, new information hinders the ability to recall older information. With proactive interference, it's the opposite: old information hinders the recall of newly learned information.
You and your roommate spent all of last night studying for your psychology test. You think you know the material; however, you suggest that you study again the next morning an hour prior to the test. Your roommate asks you to explain why you think this is a good idea. What do you tell her?
You remind her about Ebbinghaus's forgetting curve: the information you learn drops off rapidly with time. Even if you think you know the material, you should study it again right before test time to increase the likelihood the information will remain in your memory. Overlearning can help prevent storage decay.
