    Study Notes

    Definition of Memory

    • Memory involves retaining information about past events.

    Memory Processes

    • Three essential processes: Encoding, Storage, Retrieval.

    Encoding

    • The transformation of information into a format suitable for storage in the brain.
    • Types of encoding include:
      • Visual encoding: processing images.
      • Acoustic encoding: processing sounds.
      • Semantic encoding: processing meanings of words and concepts.

    Storage

    • Storing information for future retrieval.

    Retrieval

    • Accessing stored information from the brain when needed.
    • Types of retrieval:
      • Recognition: identifying previously learned information.
      • Cued recall: using prompts to retrieve information.
      • Free recall: retrieving information without aids.

    Long-Term Memory (LTM)

    • Has a large capacity and long duration, mainly coded semantically.
    • Permanent memory store.

    Short-Term Memory (STM)

    • Limited capacity (5-9 items), lasts around 30 seconds, primarily acoustically coded.
    • Temporary storage; information may fade unless rehearsed.

    Baddeley's Study on Encoding

    • Aim: Explore differences in encoding between STM and LTM.
    • Method: Four groups were tested on word recall immediately and after a delay.
    • Results: Better recall for semantically dissimilar words in LTM, indicating semantic coding over time.

    Types of Long-Term Memory

    • Episodic memory: recall of personal and specific events.
    • Semantic memory: knowledge and facts about the world.
    • Procedural memory: skills and actions.

    Multi-Store Model of Memory (Atkinson and Shiffrin)

    • Three memory stores: Sensory Register, STM, LTM.
    • Information flows from stimulus to sensory register, then STM, and finally LTM.

    STM and LTM Characteristics

    • STM: Encodes acoustically, limited capacity/duration.
    • LTM: Encodes semantically, unlimited capacity/duration.

    Rehearsal

    • A technique to maintain information in STM and transfer it to LTM through repetition.

    Serial Position Effect (Murdock)

    • Recall is influenced by the position of words in a list, with higher recall for first (primacy effect) and last words (recency effect).

    War of the Ghosts Study (Bartlett)

    • Aim: Investigate how memory is reconstructed over time, influenced by cultural expectations.
    • Method: Participants retold a culturally unfamiliar story over multiple sessions, revealing transformations in recall.
    • Conclusion: Memory is an active process, involving reconstruction of meaning rather than exact detail.

    Schemas

    • Mental frameworks that help organize and interpret information.
    • Located in long-term memory, influencing how new information is understood.

    Factors Affecting Memory Accuracy

    • Interference: Competition between memories can reduce recall accuracy.
    • Context: Environmental cues can enhance memory recall.

    McGeoch and McDonald's Study on Interference

    • Aim: Test how a competing set of words affects recall accuracy.
    • Method: Participants learned an initial list before receiving a competing list of varying similarities.
    • Results: Similar information interfered most with recall, demonstrating effects of interference.

    Godden and Baddeley's Context Experiment

    • Aim: Investigate if matching learning and recall environments improves accuracy.
    • Method: Divers learned a list of words in either wet or dry conditions and were tested in both environments.
    • Results: Higher recall in matching contexts, confirming the role of environment as a memory cue.### Godden and Baddely's Context Experiment
    • Contextual cues significantly enhance memory recall.
    • Recall accuracy improves when information is retrieved in the same environment where it was learned.
    • The relationship between context and memory suggests that environmental triggers facilitate the retrieval process.

    Findings of Godden and Baddely's Experiment

    • Information recalled in the same context leads to higher recall accuracy.
    • Memory is positively influenced by contextual cues.
    • Context acts as an effective trigger for recalling learned information.

    Issues with Godden and Baddely's Study

    • Sample sizes were limited, raising questions about generalizability.
    • Testing methods were artificial and may not reflect real-life memory retrieval.
    • Study primarily focused on short-term memory recall.
    • Effects observed may only apply to situations that closely resemble the original learning environment.

    False Memories

    • A false memory is a recollection of an event that did not occur but is perceived as a genuine memory.

    Aim of Loftus and Pickrell's Study on False Memories

    • The study aimed to explore the creation of false memories through suggestion in participants.

    Method of Loftus and Pickrell's Study

    • Involved 24 participants (3 males and 21 females) aged 18 to 53.
    • Each participant's relative provided details for four childhood event stories, three of which were true and one fabricated about getting lost in a mall.
    • Participants recalled details of the stories initially, followed by an interview weeks later to assess memory retention.
    • A second interview asked participants to identify which story was false and included a debriefing about the fabricated story.

    Results of Loftus and Pickrell's Study

    • Participants remembered 68% of 72 true episodes.
    • 19 of the 24 participants identified the "lost in the mall" story as false.
    • Six participants were able to recall details of the false event, while the remainder had no memory of it.

    Conclusion of Loftus and Pickrell's Study

    • Imagination can instill false memories, demonstrating that memory accuracy can be compromised by suggestive techniques.
    • The findings align with notions within reconstructive memory theory.
