Study Notes
Experimental Design
- Participants were divided into two groups: the Reminder group and the No-Reminder group
- Reminder group: on Day 3, the experimenter reminded participants of the List 1 learning experience, showing them objects in the blue basket
- No-Reminder group: no reminder occurred on Day 3
- Findings: on Day 5, the Reminder group showed worse recall of List 1 and more intrusions from List 2, meaning the reminder made List 1 memories less stable, more vulnerable to interference
- Interpretation: This experiment supports the theory of reconsolidation: reminding a learned memory makes it vulnerable to change
Clinical Applications of Reconsolidation
- Reconsolidation-based treatments have shown potential for treating PTSD
- Procedure: Reminding a patient of a traumatic experience and administering propranolol (a drug affecting memory consolidation) during the reminder period, aiming to block the reconsolidation process.
- Outcome: When reminded of the traumatic experience a week later, patients reported significantly lower levels of fear
Studying for Exams
- Depth of processing: aiming for a deep, meaningful understanding of the material for better retention
- Retrieval practice: instead of just reading repeatedly, actively retrieving information to test oneself and strengthen memories.
- Encoding Specificity Principle: understanding that the questions on an exam will be meaning-based, based on the way information was encoded during learning
Forgetting and Retrieval
- Retrieval failures: happen due to poor retrieval cues and interference
- Poor retrieval cues: the cues used during retrieval are not specific enough to bring back the target memory
- Interference: refers to competing memories activated by the retrieval cues, hindering access to the target memory
- Intrusions: the result of interference, where incorrect information is retrieved instead of the correct one
Example of Interference
- Study: participants learn lists of U.S. presidents and their details
- Findings: retrieving similar information about different presidents can cause interference, leading to intrusions, such as mistakenly retrieving information about Adams when asked about Madison
- Conclusion: interference can lead to incorrect retrieval or even the inability to retrieve any information at all.
Interference and Distinctiveness
- Reducing interference: creating distinct memories by using deep processing techniques
- Deep processing: making learned items unique through deeper understanding and meaningful connections
- Summary of Retrieval Failure: forgetting often originates from retrieval failure, either due to ineffective cues or competing memories during retrieval.
Consolidation
- General principle: new memories are initially weak and tend to get stronger with time
- Consolidation: the brain processes that strengthen memories over time
- Synaptic Consolidation: takes place over minutes to hours and involves changes to synapses
- System Consolidation: takes place over months to years and involves the reorganization of memories in the brain
System Consolidation and Retrograde Amnesia (RA)
- Evidence: retrograde amnesia provides evidence for system consolidation. Patients with RA experience memory loss most severe for recent memories and least severe for distant memories
- Temporal Gradient: memory loss is greatest for recent memories and gradually decreases for older memories
- Explanation: because system consolidation takes a long time, recent memories are more susceptible to disruption than older memories
Consolidation and Sleep
- Sleep: plays a crucial role in memory consolidation
- Gais et al., 2006 Participants studied vocabulary words and were divided into two groups: Sleep group and Awake group.
- Results: the Sleep group showed significantly better recall of the learned vocabulary compared to the Awake group, indicating sleep enhances memory consolidation.
- Interpretation: sleep seems to facilitate memory consolidation, potentially enhancing retention of new information studied immediately before sleep.
Caveat:
- While sleep appears to support memory consolidation, the Awake group in the study might have experienced more interference from new experiences during their waking period, which could have negatively impacted their memory performance.
