Study Notes
Insight
- Sudden realization of a solution to a problem.
- Kohler's Chimpanzee Study demonstrated insight by observing chimpanzees using tools to reach out-of-reach food.
Obstacles to Problem Solving
- Confirmation Bias: The tendency to favor information that confirms existing beliefs while ignoring conflicting evidence.
- Fixation/Functional Fixedness: The inability to see a problem from a new perspective, limiting objects to their usual use.
- Mental Set: Approaching problems in a familiar way, even when a new approach might be more efficient.
-
Overconfidence: Overestimating the validity of one's knowledge and beliefs.
- Sunk-Cost Fallacy: Continuing a course of action due to previously invested resources, even if it's unwise or dangerous.
- Belief Perseverance: Holding onto initial beliefs even after being presented with opposing evidence.
-
Framing/Wording Effects: How a statement or question is worded affects decision-making and judgments.
- Nudge: Subtle changes in how choices are presented, influencing decisions without restricting options.
- Priming: Unconscious activation of related concepts in memory, influencing thoughts and behaviors.
Forming Judgments
- Intuition: Effortless, immediate, automatic feelings or thoughts.
-
Representativeness Heuristics: Judging the likelihood of something based on how well it matches a prototype.
- Gambler's Fallacy: The mistaken belief that past random events affect future outcomes, linked to representativeness heuristics because both involve comparing prototypes.
-
Availability Heuristics: Estimating the likelihood of events based on their availability in memory.
- Example: Fearing car crashes more after seeing a news report about a crash, even though the statistical likelihood is rare.
Memory and Measurement
- Memory: The persistence of learning over time.
- Measured through: Recall, recognition, and relearning.
- Alzheimer's Disease: Neurodegenerative disorder that progressively destroys memory and cognitive abilities.
Memory Terms
- Recall: Retrieving information without cues.
- Recognition: Identifying previously learned information from a set of choices.
- Relearning: Measuring how quickly information is relearned after being forgotten.
Stages of Memory
- Sensory Memory: Holds sensory information for a few seconds or less.
- Short-Term Memory: Active memory that holds a few items briefly.
-
Long-Term Memory: Stores memories indefinitely, potentially for a lifetime.
- Prospective Memory: Remembering to perform future tasks.
- Rehearsal: Conscious repetition of information to maintain it in working memory or to encode it into long-term memory.
Working Memory
- Working Memory: A system that holds and manipulates information temporarily for cognitive tasks.
- Maintenance Rehearsal: Repeating information to keep it active in working memory.
- Elaborative Rehearsal: Linking new information to existing knowledge, improving long-term retention.
Parts of Working Memory
- Central Executive: Coordinates working memory's processes, focusing attention and integrating information.
Strategies to Improve Memory
- Chunking: Grouping information into manageable units, aiding in long-term storage.
- Mnemonics/Mnemonic Devices: Memory aids using vivid imagery or organizational devices, such as acronyms, to improve recall and recognition.
- Method of Loci: A mnemonic device that involves visualizing familiar locations to help recall information.
- Hierarchies (or Categories): Organizing information into broad concepts and subdividing them into narrower concepts, improving understanding and recall.
- Spacing Effect: Distributing study sessions over time leads to better long-term retention than massed practice.
- Massed Practice: Cramming information in one sitting, which is less effective for long-term retention.
- Distributed Practice: Spacing learning over time enhances retention.
- Memory Consolidation: Short-term memories become long-term, which happens during sleep.
- Testing Effect: Retrieving information during testing improves long-term retention more than solely reading or reviewing material.
- Interleaving: Mixing different topics or subjects during study sessions to improve learning.
Levels of Processing Memory
-
Shallow Processing: Encoding on a basic level, based on the structure of words.
- Example: Recalling a word's appearance but not its meaning.
-
Deep Processing: Encoding semantically, based on the meaning of words, leading to better retention.
- Example: Remembering the definition and significance of a word.
Levels of Processing Memory (Details)
- Structural: Focus on physical features like the appearance of words.
- Phonemic: Focus on sound, like rhyming.
- Semantic: Focus on meaning, leading to deeper understanding and better retention.
Long-Term Memory Capacity
- The capacity of long-term memory is virtually limitless.
Types of Long-Term Memory
- Semantic Memory: Memory for general knowledge and facts about the world.
- Episodic Memory: Memory for specific personal events and experiences.
Brain Regions and Memory
- Frontal Lobe: Working memory and decision-making.
- Hippocampus: Critical for forming new long-term memories.
- Cerebellum: Involved in procedural memories and motor skills.
- Basal Ganglia: Involved in motor memory and habit formation.
- Amygdala: Causes emotional memories, especially fear-related.
Infantile Amnesia and Brain Development
- The underdeveloped hippocampus and prefrontal cortex prevent infants from forming long-term episodic memories, potentially contributing to infantile amnesia.
Memory Consolidation
- Memory Consolidation: The process of strengthening new memories and making them more resistant to interference.
Breakdown of Memory
- Implicit Memory (Procedural and Conditional Memories): Memories that are not consciously recalled, such as skills and habits.
- Explicit Memory (Episodic and Semantic Memories): Memories that can be consciously recalled.
Flashbulb Memories
- Flashbulb Memories: Highly detailed and vivid memories of emotionally significant events, like remembering where you were during a major natural disaster.
Retrieval Cues
- Priming: Unconscious activation of related associations, like being more likely to recognize the word "boss" after seeing the word "manager".
- Context-Dependent Memory: Recall is better when you are in the same place you first learned it.
- Encoding Specificity Principle: Cues and contexts specific to a memory will be most effective in helping recall.
- State-Dependent Memory: Memory is best retrieved when in the same emotional or physiological state as when the memory was encoded.
- Mood-Congruent Memory: The tendency to recall experiences that match one's current mood.
-
Serial Position Effect:
- Primacy Effect: Better recall for items at the front of a list.
- Recency Effect: Better recall for items at the end of a list.
- Metacognition: Awareness and understanding of one's thought processes.
- Testing Effect: Improvement of memory after retrieving information, rather than simply rereading it.
- Interleaving: Mixing different topics or subjects during study sessions to improve learning.
Context-Dependent vs. State-Dependent Memory
- Context-Dependent Memory is tied to the environment, while State-Dependent Memory is tied to internal states like mood or physical conditions.
Amnesia
- Amnesia: Loss of memory, typically due to brain injury or illness.
Types of Amnesia
- Anterograde Amnesia: Inability to form new memories after an injury.
- Retrograde Amnesia: Inability to recall past memories from before an injury.
Ebbinghaus' Forgetting Curve
- Ebbinghaus' Forgetting Curve: Shows that as time passes, we tend to forget around 60% of learned data, and the remaining 40% sticks with us for the rest of our lives.
Reasons for Forgetting
- Encoding Failure: Information never enters long-term memory.
- Storage Decay: Memory fades over time if not accessed.
-
Retrieval Failure: Inability to access stored memories due to interference or other factors.
- Tip-of-the-Tongue Phenomenon: A temporary inability to retrieve information that feels just out of reach.
- Interference: New or existing information interferes with the retrieval of stored information.
- Motivated Forgetting/Repression: A basic defense mechanism that banishes anxiety-arousing thoughts, feelings, and memories from consciousness.
Types of Interference
- Proactive Interference: Older information disrupts the recall of newer information.
- Retroactive Interference: Newer information disrupts the recall of older information.
Example of Proactive and Retroactive Interference
- Remembering an old password (proactive) interferes with remembering a new one (retroactive).
Memory Construction
- Reconsolidation: The process of recalling a memory and potentially altering it during storage.
- Misinformation Effect: When incorrect information presented after an event alters memories of the event.
- Imagination Inflation: Imagining an event can increase confidence that it actually happened.
