    Study Notes

    Encoding Specificity Principle

    • Retrieval is more likely to be successful when retrieval conditions are similar to encoding conditions.
    • Context Effects: Remembering information easier when retrieval occurs in the same setting as learning.
    • Mood Congruence: Positive mood is associated with remembering positive events, and a negative mood is associated with remembering negative events.

    Can We Trust Our Memories?

    • Flashbulb Memories: A vivid and detailed memory of the circumstances surrounding a shocking or highly emotional event.
    • Eyewitness Testimony: Remembering events, but it can be unreliable.
    • Elizabeth Loftus: A leading expert on eyewitness testimony.

    Hermann Ebbinghaus: The Forgetting Curve

    • Studied forgetting using nonsense syllables.
    • Found that much of what we forget is lost relatively soon after learning.
    • How quickly we forget depends on how well the material was encoded, how meaningful the material was, and how frequently the material was rehearsed.

    File Details

    • Dementia: A progressive decline in cognitive function, affecting memory, reasoning, and other mental abilities.
    • Alzheimer’s Disease: A chronic neurodegenerative disease that impairs memory, thinking, and behavior.
    • It is the most common cause of dementia.
    • It causes the brain to develop beta-amyloid plaques and neurofibrillary tangles.

    Alzheimer's Disease

    • Early dementia involves mild memory impairment.
    • It progresses to more pervasive memory loss and confusion.
    • Internal brain damage becomes widespread.
    • Individuals become unable to communicate and lose their sense of self and identity.
    • Finally, complete incapacitation and death.

    Ten Steps to Boost Your Memory

    • Commit the necessary time to studying.
    • Organize information to be learned.
    • Elaborate on the material being studied by providing details.
    • Explain the material to a friend.
    • Use visual imagery to create connections to information.
    • Reduce interference by studying one topic at a time.
    • Counteract the serial position effect by reviewing material that is difficult to remember.
    • Use contextual cues to help jog memories.
    • Use a mnemonic device for remembering lists.

    Encoding Failure

    • A common reason for forgetting is when information is not encoded into long-term memory.
    • Absentmindedness: Lapses in attention, leading to forgetfulness.
    • Prospective Memory Error: Failure to remember a future task (retrieval cue failure).

    Why Do We Forget?

    • Decay Theory: Memory traces fade away over time due to normal brain processes.
    • Challenges: Some research shows memories can be remembered decades after they were learned.

    Interference Theory

    • Forgetting results from the interference of memories with each other.

    1. Retroactive Interference

    • New learning interferes with the recall of old information.

    2. Proactive Interference

    • Prior learning interferes with the recall of new information.

    Long-Term Memory Organization

    • Clustering: Related items are grouped together to form higher-order categories.
    • Semantic Network Model: Concepts are linked together in a network, with stronger associations having shorter paths between them.
    • Activation of one concept spreads to other associated concepts in the network.

    The Forgetting Curve

    • The forgetting curve illustrates the decline in retention of information over time.
    • It shows that forgetting happens rapidly initially and then levels off.

    Why Do We Forget?

    • Encoding Failure: Information was not initially encoded into long-term memory.
    • Retrieval Cue-Failure: The lack of appropriate cues to trigger retrieval of stored information.

    Retrieval Cues

    • Cues, prompts, or hints that trigger the recall of information stored in long-term memory.
    • Often helps access stored information that seemed unavailable.

    Tip-of-the-Tongue Phenomenon

    • The sensation of knowing that information is stored in long-term memory but being unable to retrieve it.
    • People can often identify the first letter and the number of syllables in the word.
    • They may produce words with similar meanings or sounds.
    • Most TOT experiences are resolved within a few minutes.

    Testing Retrieval

    • Cued Recall: Remembering information with a retrieval cue.
    • Recognition: Identifying correct information from possible choices.
    • Recall: Retrieving information with no cues (free recall).

    File Details

    • Henry Gustav Molaison (H.M.): A patient who underwent surgery to remove his hippocampus, leading to severe anterograde amnesia.
    • Hippocampus: Crucial for encoding new memories and transferring them to long-term storage.
    • Brain structures involved in memory: Prefrontal cortex, Amygdala, Hippocampus, Medial Temporal Lobe, Cerebellum.

    Alzheimer’s Disease

    • Dementia is progressive deterioration of cognitive function.
    • Alzheimer's Disease is a progressive disease that destroys the brain's neurons, impairing memory, thinking, and cognitive abilities.
    • It is the most common cause of dementia.
    • The brains of those with Alzheimer’s develop beta-amyloid plaques and neurofibrillary tangles.

    Motivated Forgetting

    • Suppression: Consciously withholding an undesired memory from awareness.
    • Repression: Unconsciously pushing an undesired memory out of awareness.

    Source Confusion

    • Source confusion: Attributing a memory to the wrong source.
    • False memory: A fabricated memory that did not actually occur.

    Massed Versus Spaced Practice Effect

    • Spaced practice is more effective for retaining learned material than massed practice.

    Biological Basis of Memory

    • Karl S. Lashley: Searched for the localized memory trace (engram), but concluded that memories are distributed throughout the brain.
    • Richard F. Thompson: Found evidence that memories for simple classically conditioned responses are localized in the cerebellum.

    Amnesia: Loss of Memory

    • Retrograde Amnesia: Loss of memory for past events.
    • Anterograde Amnesia: Loss of the ability to form new memories.
