Study Notes
Implicit Emotional Conditioning
- Emotional responses can be classically conditioned and are not always consciously recalled
- Smell can cause emotional responses, possibly due to implicit memories
- Songs can also evoke specific emotions, which could be due to implicit memories
Autobiographical Memories
- Episodic memories are another term for autobiographical memories.
- It is difficult for most people to remember details from years past, such as what they wore or ate on a specific day.
- Marilu Henner has a superior autobiographical memory, a condition known as hyperthymesia
- Hyperthymesia is rare, affecting fewer than 20 individuals, and only a few have been studied.
- Hyperthymesia often appears in adolescence, but two children in the US reportedly have memories from before their tenth birthdays.
Retrieval
- Retrieval is the process of bringing stored information back to conscious awareness.
- The hippocampus is important for processing explicit memories
- Damage to the hippocampus can impair the ability to form new semantic memories.
- Even with hippocampal damage, implicit memories can still be created.
Cerebellum and Prefrontal Cortex
- The cerebellum plays a role in implicit memories, such as procedural memory, motor learning, and classical conditioning.
- Damage to the cerebellum can impair the learning of conditioned responses.
- Brain scans suggest the prefrontal cortex is involved in memory processing.
- The left inferior prefrontal cortex is more active in semantic tasks than perceptual tasks.
- Encoding is associated with left frontal activity while retrieval is associated with right frontal activity.
Neurotransmitters
- Neurotransmitters, including epinephrine, dopamine, serotonin, glutamate, and acetylcholine, are involved in memory.
- The specific role of each neurotransmitter is still being researched.
Suggestibility
- Suggestibility is the effect of misinformation from external sources that can lead to the creation of false memories
- Eyewitness testimonies can be unreliable as they are influenced by suggestions.
Eyewitness Misidentification
- Faulty eyewitness identification can lead to wrongful convictions.
- The Innocence Project found that eyewitness misidentification is the leading cause of wrongful convictions.
Mnemonic Devices
- Mnemonic devices are strategies for improving memory.
- Examples include acronyms, such as HOMES for remembering the Great Lakes, and vivid mental imagery.
- The effectiveness of a mnemonic device depends on the strategy used and its memorability.
Memory Improvement Strategies
- Expressive writing, especially about traumatic experiences, can boost short-term memory.
- Studying over time and spacing out study sessions allows for memory consolidation.
- Cramming can hinder memory consolidation and impede access to other learned information.
- Review material regularly, organize and study notes, and take practice quizzes.
- Link new information to existing knowledge.
- Use index cards for study, separating cards into those correctly and incorrectly answered to focus on areas needing further review.
- Study in quiet environments with minimal distractions.
- Aerobic exercise promotes neurogenesis in the hippocampus, which is beneficial for memory.
- Getting enough sleep allows the brain to consolidate information into long-term memory.
Short-Term Memory Retention
- Short-term memory (STM) is limited in capacity and duration.
- Peterson and Peterson (1959) studied STM using trigrams, finding 80% recall after 3 seconds, but only 10% after 18 seconds, suggesting decay within 18 seconds.
- Memory trace decay occurs as the memory trace becomes less activated over time.
- Keppel and Underwood (1962) found that proactive interference also affects STM retention.
- Proactive interference occurs when previously learned information interferes with learning new information.
- STM is affected by both memory trace decay and proactive interference.
Long-Term Memory
- Long-term memory (LTM) has an unlimited storage capacity.
- LTM is believed to be organized in semantic networks, which are interconnected concepts.
- Concepts are categories or groupings of linguistic information, images, ideas, or memories.
- LTM is often studied using observable behaviors, such as skilled actions.
- Implicit procedural memory stores information about how to perform skills, like riding a bike or driving a car.
- Implicit priming is another type of implicit memory where prior exposure to a stimulus affects the response to a later stimulus.
Types of Long-Term Memory
- Explicit memory includes episodic and semantic memory.
- Implicit memory includes procedural memory and things learned through conditioning.
- Semantic networks are believed to be arranged hierarchically.
Retrieval of Information
- There are three ways to retrieve information from LTM: recall, recognition, and relearning.
- Recall involves accessing information without cues.
- Recognition involves identifying previously learned information.
- Relearning involves re-acquiring information that was previously learned.
Brain Functions Involved in Memory
- Memories are stored in various parts of the brain, not just one area.
- Key brain regions involved in memory include the hippocampus, amygdala, and cerebellum.
Storage Decay
- Storage decay occurs when unused information fades over time.
- Ebbinghaus's forgetting curve shows that an average person loses 50% of memorized information after 20 minutes and 70% after 24 hours.
Absentmindedness
- Absentmindedness is a memory error caused by lapses in attention.
- It is often characterized by forgetting something due to a break in focus.
- Examples include forgetting where you put your keys or forgetting what you were about to do when you enter a room.
Memory
- Memory is the ability to store and retrieve information.
- Memory is an information processing system.
- Memory is similar to how a computer processes data.
Encoding
- Encoding refers to how we get information into our brains.
- Encoding can be automatic or effortful.
- Types of encoding include visual (mental), acoustic, and semantic.
- Visual encoding is based on image processing of the information.
- Acoustic encoding focuses on sounds.
- Semantic encoding is based on meanings of words.
Retrieval
- Retrieval refers to the ability to access stored information.
- Retrieval can be affected by various factors.
- The ability to recall information can be influenced by the situation or individual factors.
Brain & Memory
- Parts of the brain are involved with memory.
Memory Problems
- When areas of the brain are affected, one can suffer memory loss.
- Clive Wearing suffered from memory loss after a brain infection affecting his memory areas.
- Clive Wearing was an English musician with herpes encephalitis.
Enhancing Memory
- Techniques can be used to enhance memory.
Memory
- Memory is an information processing system similar to a computer
- To remember, information must be attended to, encoded, stored, and retrieved
- Encoding refers to the process of getting information into the brain
Types of Encoding
- Visual (Mental): Encoding information by creating mental images
- Acoustic: Encoding information by focusing on sounds
- Semantic: Encoding information by understanding its meaning through words
Retrieval
- Retrieval refers to accessing stored information
- Retrieval success can be influenced by factors like encoding strategies and emotional state
Brain Areas Involved in Memory
- Different brain areas are responsible for various aspects of memory
Memory Problems
- Damage to specific brain regions can lead to memory loss
- Clive Wearing, a musician, suffered severe memory impairment due to herpes encephalitis affecting memory-related brain areas
Ways to Enhance Memory
- The presentation mentions using music or pleasant associations as potential memory enhancement strategies
- The presentation concludes with a thank you, suggesting a focus on practical memory techniques might be included in a later section.
