Psych #2 - Memory Flashcards
What are the processes of memory?
Encoding, Storage, and Retrieval
What is encoding?
Processes used to store information in memory
What is storage?
Processes used to maintain information in memory
What is retrieval?
Processes used to get information back out of memory
What are some methods used to study memory?
Recall versus recognition tasks.
What’s an example of a recall task?
A fill-in-the-blank question tests your recall. You have to generate an answer.
What is an example of a recognition?
A multiple-choice question
What is free recall?
Recall of the words you can from the list you saw previously
What is serial recall?
Recall the names of all the previous presidents in the order they were elected. Need to recall order as well as item names
What is cued recall?
Give participants some clue to trigger recall. Paired associates - Dishtowl-locomotive, switch-paper
What are some explicit memory tasks?
This involves conscious recollection (can be recall or recognition) participants knows they are trying to retrieve information from their own memory
What are implicit memory tasks?
This requires participants to complete a task. The performance of the task indirectly indicates memory.
What is the main point to remember about recognition, recall, and relearning?
Tests of recognition and of time spent relearning demonstrate that we remember more than we can recall
What is procedural memory?
Knowing how to do something. Like ride a bike.
What is declarative memory?
Memory for facts (semantic) or events (autobiographical)
What was Richard Atkinson and Richard Shiffrin proposed three-staged memory model?
- We first record to-be-remembered information as a fleeting sensory memory.
- From there, we process information in short-term memory, where we encode it through rehearsal.
- Finally, information moves into long-term memory for later retrieval.
What were Sperlings tests about the capacity of iconic (visual) memory?
Whole report procedure: flashed a matrix of letter quickly you had to just identify as many letters as possible and participants typically remembered 4 letters.
Partial Report Procedure: Flash a matrix of letters quickly and participants are told to report one row at a time. (bottom row). Participants were able to report any row requested.
Sensory Memory
Can only recall a few items, but can select which ones from a larger set. Large capacity and held for a very short duration. The old information is pushed out by incoming. Attention determines what makes it into next stage.
Short-term memory?
There is a limited capacity (7 or so items). Take in from sensory memory and long-term memory. persists as long as it is rehearsed.
Main points from Peterson and Peterson duration of short-term memory
- Subjects memorized nonsense words (MJK, ZRW, BPH)
- Distractor task used during waiting period - count backwards
- When a cue was given, subjects tried to recall the letters.
- Main point if you are unable to rehearse information, it will not be passed to long-term memory, providing further support for multi-store model and the idea of discrete components.
What is chunking?
It’s easier to chunk numbers into years like 1865, 1953, 1980 into our memory rather than just a string of digits.
What are the main points about long-term memory?
It’s fed by short-term memory. It’s virtually unlimited capacity and unlimited duration. Getting into LTM takes effort.
Bahrick’s main points from his high school experiment?
People who had graduated 25 years earlier could not recall many of their old classmates, but they could recognize 90 percent of their pictures and names.
What was Craik and Lockharts main points from their levels of processing model of memory?
- Different ways we process information lead to different strengths of memories.
- Deep processing leads to better memory (elaborating according to meaning leads to a strong memory).
- Shallow processing emphasize the physical features of the stimulus. (memory trace is fragile and quickly decays)
- Distinguished between maintenance rehearsal and elaborative rehearsal
What is the Craik and Watskin’s study with target words?
Participants listened to lists of words. Task was to recall the word in the list which began with a particular. Varied the number of intervening words that came in between the words that began with the target letter.
What were the results of Craik and Watkin’s study?
Recall of words was independent of the length of time. More intervening words didn’t help. They found that maintenance rehearsal did not automatically lead to Long Term Memory.
What was Craik and Tulving’s study?
Participants studied a list of words in 3 different ways. Is the word in capital letters, does the word rhyme with dog, does the word fit in this sentence?
What were the results of Craik and Tulving’s study?
Most recalled sentences, then rhyme, and least with capital letters.
Why was the sentence in the Craik and Tulving study most effective?
This was most effective because the deeper, semantic processing triggering yielded a much better memory.
What is the self-reference effect?
Subjects have to determine if the words in a list describe them..Smart,talkative,diligent. High levels of recall, even if you through shy, diligent did not describe you but even higher recall for words that did describe. Bigger effect for positive traits.
What were some criticisms of the Long processing model?
They didn’t have a good enough definition of what it means to be a deeper or shallow memory. Transfer appropriate processing effect (morris)
What was morris, bransford, and franks main ideas?
Two processing tasks: semantic and rhyme.
Two types of tests: standard yes/no recognition vs. rhyme test. memory performance also depends on the match between encoding processes and type of test.
What is a standard recognition test?
Old/new recognition test. Did you see train or tree first?
What is a rhyme recognition test?
Words that either rhymed or did not rhyme with studied words
What is the purpose of working memory?
Mental workspace whenever you need to retain some information while processing other information (mental arithmetic like bigs numbers being added up)
What is working memory?
Working memory refers to the system or systems involved in the temporary storage of information in the performance of cognitive skills such as reasoning, learning and comprehension
