How Do We Retrieve Memories? Whether memories are implicit or explicit, successful retrieval depends on how they were encoded and how they are cued

Implicit and Explicit Memory Implicit Memory that was not deliberately learned or of which you have no conscious awareness or memory of ever having learned them Procedural memories are often implicit, but not always In daily life, people rely on implicit memory in the form of procedural memory…. . …the type of memory that allows people to remember how to tie their shoes or ride a bicycle without consciously thinking about these activities.

Implicit and Explicit Memory For Example: Memory that has -Answers to a test been processed with -Remembering the attention and can be time of an consciously recalled appointment -Recalling your favorite Christmas

Retrieval Cues Stimuli that are used to bring a memory to consciousness or into behavior Cue Card

§ Déjà Vu (French for ‘already seen’) § Cues from the current situation may subconsciously trigger retrieval of an earlier similar experience § "I've experienced this before. "

Retrieval Cues n Priming Technique for retrieving implicit memories by providing cues that stimulate a memory without awareness of the connection between the cue and the retrieved memory

Priming n If you are presented with the following words: assassin, octopus, avocado, mystery, sheriff, climate

Priming n An hour later, you would easily be able to identify which of the following words you had previously seen: twilight, assassin, dinosaur, mystery

Priming n However, an hour later, you would also have a much easier time filling in the blanks of some of these words than others: ch_ _ nk o _ t _ _ _ us _ oog _ y _ _ l _ m _ te

Priming n While you did not actively try to remember “octopus” and “climate” from the first list, they were primed in the reading, which made them easier to identify in this task chipmunk octopus boogeyman climate

Retrieving Explicit Memories • Anything stored in LTM must be “filed” according to its pattern or meaning. • So the best way to add material to the LTM is to associate it with material already in the LTM

Recall and Recognition Recall Technique for retrieving explicit memories in which one must reproduce previously presented information Example: On an essay test, you must create answers entirely from memory with only the help of a few cues.

Recall and Recognition Technique for retrieving explicit memories in which one must identify present stimuli as having been previously presented Example: On a multiple choice test, you only have to identify a previous stimulus (answer)

Other Factors Affecting Retrieval Encoding Specificity Principle The more closely the retrieval clues match the form in which the information was encoded, the better the information will be remembered Example: Test questions need to be presented on a test in a similar context in which they were presented in the class.

Other Factors Affecting Retrieval Mood Congruent Memory A memory process that selectively retrieves memories that match one’s mood • A happy moods is likely to trigger happy memories • Depression perpetuates itself through the retrieval of depressing memories

TOT (tip of the tongue) Phenomenon The inability to recall a word, while knowing that it is in memory. Explained by a poor match between a retrieval cue and the LTM

Why Does Memory Sometimes Fail Us? Most of our memory problems arise from memory’s “Seven Sins” – which are really by-products of otherwise adaptive features of human memory

Memory Failure

Memory’s “Seven Sins” Transience Absent. Mindedness Misattribution Suggestibility Bias Persistence Blocking

Transience Long term memories gradually weaken over time Forgetting Curve A graph plotting the amount of retention and forgetting over time for a certain batch of material Copyright © Allyn & Bacon 2007

Percent retained Ebbinghaus’s Forgetting Curve 60 50 40 30 20 10 0 5 10 15 Days 20 25 Recall decreases rapidly, then reaches a plateau, after which little more is forgotten Copyright © Allyn & Bacon 2007 30

Absent-Mindedness Forgetting caused by lapses in attention

Blocking • Forgetting that occurs when an item in memory cannot be accessed or retrieved • Caused by interference – Proactive interference – Retroactive interference – Serial position effect

Blocking Proactive Interference: Earlier learning interferes with memory for later information Old memories move ‘forward’ in time to block your attempt at new learning Example: When you drive a new far, you still reach for where the radio. Copyright was© Allyn in &your old car Bacon 2007

Blocking Retroactive Interference: New information interferes with memory for information learned earlier New material reaches back into your memory to block old material • Example: After driving your Mom’s car that has no clutch, you forget to use the clutch when your drive you own car Copyright © Allyn & Bacon 2007

Blocking Serial Position Effect: Interference related to the sequence in which information is presented …usually items in the middle of a sequence are remembered less than lose first (primacy effect) or last (recency effect)

Serial Position Effect Probability of Recall 1. 00 Theoretically, the primacy effect represents recall from long-term memory and the recency effect represents recall from short-term memory. Primacy Effect . 50 . 00 1 5 Recency Effect 10 Serial Position of Item Copyright © Allyn & Bacon 2007 15

• • • In a 1966 experiment, subjects were shown a series of 15 words, then tested for their recall of the words immediately or after 30 seconds. When tested immediately, people remembered items at the beginning and end of the series better than those in the middle. Memory for words at the end of the list faded when the test was delayed 30 seconds.

Next-in-line-Effect: When you are so anxious about being next that you cannot remember what the person just before you in line says, but you can recall what other people around you say.

Misattribution • Memory fault that occurs when memories are retrieved, but they are associated with the wrong time, place, or person The older the memory, the more likely it is to suffer misattribution. Copyright © Allyn & Bacon 2007

The Challenger Study • Immediately after the Challenger tragedy, researchers at Emory University asked students to write down what they were doing when they heard the news. • A year later, the researchers asked the same students to write down their memories of the event again. • These later descriptions were riddled with misattributions. • But misattributions can be startlingly strong. • When told of the discrepancies, the students had trouble believing that their memories were inaccurate. • Three years later, when the students were once again asked to recall the Challenger explosion, their recollections were closer to their second accounts. 1986

Suggestibility When external cues distort or create memories • Suggestibility refers to false memories that you develop because someone or something gives you some key information at the same time that you’re trying to retrieve a memory.

Suggestibility • Imagine that you saw someone fleeing from a car as its antitheft alarm was blaring. • You didn’t get a good look at the thief, but another person on the street insisted that it was a man wearing a green plaid jacket. • Later, when the police show you photos of possible suspects, you’re confused until you see a man dressed in green plaid coat. • Then you point to him.

Suggestibility Misinformation Effect The distortion of memory by suggestion or misinformation Fabricated Memories False memories created through credible suggestions

Misinformation Effect • Loftus and Palmer found in studies that after seeing two cars collide, responses depended heavily upon how the questions were worded…. using the word ‘smash’ instead of ‘hit’

Misinformation Effects A week later they were Eyewitnesses reconstruct their memories Group when A: How fast were the cars questioned about the event. asked: going when they hit each other? Was there any broken glass? Group B: How fast were the cars Group B (smashed into) going when they smashed into reported more broken glass each other? than Group Aaccident. (hit).

Loftus’ and Palmer’s research shows that if false memories (lost at the mall or almost drowning in a lake) are implanted in individuals, they construct (fabricate) these memories
