- Interactionist: Language develops through interactions between social experience and biological abilities.
The Brain and Language
- Broca's Area: Left frontal cortex; involved in language production.
- Wernicke's Area: Left temporal cortex; involved in language comprehension.
- Right Hemisphere: Processes verbal meaning and active during language tasks.
Concepts and Categories
- Concepts: Mental representations grouping shared features of related stimuli.
- Necessary Condition: Must be true for a category member.
- Sufficient Condition: Proves category membership if true.
- Theories
- Prototype Theory: Comparing new items to the most typical category member.
- Exemplar Theory: Judging by comparing new instances to stored memories of other category examples.
Brain Areas
- Left Hemisphere & Visual Cortex: Forming prototypes.
- Right Hemisphere, Prefrontal Cortex, Basal Ganglia: Recognizing exemplars.
- Category-Specific Deficit: Neurologial syndrome affecting the recognition of specific categories while sparing others.
What is Learning?
- Learning: Acquiring knowledge, skills, or responses from experience, leading to a relatively permanent change in behavior or understanding.
- Non-Associative Learning
- Habituation: Gradual reduction in response after repeated exposure.
- Sensitization: Increased response following a stimulus.
- Associative Learning
- Classical Conditioning: Behavior controlled by external stimuli.
- Unconditioned Stimulus (US): Naturally evokes a response.
- Unconditioned Response (UR): Reflexive response to the US.
- Conditioned Stimulus (CS): Natural stimulus that evokes a learned response.
- Conditioned Response (CR): Learned reaction to the CS resembling the UR.
- Classical Conditioning Processes: Acquisition, extinction, spontaneous recovery, second order.
- Generalization: CR occurs with stimuli similar to the CS.
- Discrimination: Differentiating between similar stimuli.
- Fear Conditioning: Amygdala involvement in associating stimuli with fear.
- Classical Conditioning: Behavior controlled by external stimuli.
Operant Conditioning
- Operant Conditioning: Behavior is influenced by its consequences.
- Law of Effect: Behaviors followed by positive outcomes are repeated; negative outcomes decrease behavior likelihood.
- Reinforcement:
- Positive Reinforcement: Adding a stimulus to increase behavior.
- Negative Reinforcement: Removing a stimulus to increase behavior.
- Punishment:
- Positive Punishment: Adding a stimulus to decrease behavior.
- Negative Punishment: Removing a stimulus to decrease behavior.
- Schedules of Reinforcement
- Fixed interval
- Variable interval
- Fixed ratio
- Variable ratio
- Cognitive Elements of Operant Conditioning:
- Latent Learning
- Cognitive Map
- Neural Elements: Brain pathways and structures deliver rewards, reinforcing learned behaviors.
- Observational Learning (Bandura)
- Definition: Learning by observing others.
- Bobo Doll Experiment
- Diffusion Chain
- Mirror Neurons
- Implicit Learning: Learning without conscious awareness.
Rational Decision-Making
- Rational Decision-Making: Based on probabilities and value judgments.
- Availability Bias: Overestimating the likelihood of memorable events.
- Heuristics: Quick strategies (don't guarantee a solution).
- Optimism Bias: Belief in higher personal likelihoods of positive outcomes.
- Problem-Solving Strategies: Means-Ends Analysis (breaking down goals).
- Algorithms: Defined procedures (guarantee a solution).
Memory Defined
- Memory: The ability to store and retrieve information over time.
- Three Key Functions
- Encoding: Transforming perceptions into lasting memories.
- Storage: Maintaining information over time.
- Retrieval: Accessing encoded and stored information.
- Encoding: Transforming Perceptions into Memories
- Memories are constructed by combining existing knowledge with new information.
- Three Major Encoding Methods:
- Semantic Encoding: Relates new information meaningfully to existing knowledge.
- Visual Imagery Encoding: Stores information by converting it into mental pictures.
- Organizational Encoding: Categorizing information by relationships among items.
- Encoding of Survival-Related Information: Evolutionary theories suggest memory mechanisms enhance survival.
Storage
- Sensory Storage:
- Iconic Memory: Fast-decaying store of visual information.
- Echoic Memory: Fast-decaying store of auditory information.
- Short-Term Memory (STM)
- Non-sensory information for a short duration (seconds to minutes).
- Limited capacity (approximately 7 items).
- Rehearsal: Keeps information in STM.
- Chunking: Groups small bits of information into larger units.
- Working Memory: Active maintenance and manipulation of information.
- Working Memory Model
- Limited-capacity system with two subsystems (episodic buffer)
- Visio-spatial Sketchpad
- Phonological Loop
- Limited-capacity system with two subsystems (episodic buffer)
- Long-Term Memory (LTM)
- Stores information for extended durations.
- No known capacity limits.
- Hippocampus and Memory: Crucial for transferring information to LTM but also retrograde and anterograde amnesia.
Retrieving Memories
- Retrieval Cues: External information triggers retrieval of stored memories.
- Encoding Specificity Principle: Cues are effective if they recreate the initial encoding context.
- State-Dependent Retrieval: Information is better recalled in the same state as encoding.
- Transfer-Appropriate Processing: Effective memory transfer occurs when contexts match between encoding and retrieval.
- Consequences of Retrieval: Strengthening or weakening subsequent memories.
- Types of Long-Term Memory
- Explicit Memory: Conscious retrieval of past experiences
- Semantic Memory: General knowledge and facts.
- Episodic Memory: Personal experiences tied to specific times and places.
- Implicit Memory: Influence of past experience on behavior without conscious awareness
- Procedural Memory: Gradual acquisition of skills through practice.
- Priming: Enhanced ability to recall stimuli after recent exposure (perceptual and conceptual priming).
- Explicit Memory: Conscious retrieval of past experiences
Forgetting and Memory Failures
- Decay Theory: Neglected memories fade over time.
- Interference: Old information disrupts new learning (Proactive and Retroactive Interference).
- Seven Types of Memory Failures:
- Transience: Forgetting over time.
- Absentmindedness: Lapses in attention.
- Blocking: Inability to retrieve information (Tip-of-the-Tongue phenomenon).
- Misattribution: Assigning memory to the wrong source.
- Suggestibility: Incorporating misleading information.
- Bias: Current knowledge distorts past recollection.
- Persistence: Unwanted recollection of traumatic events.
Memory and Emotion
- Amygdala's role in memory: Enhances recall of emotional events; distinguishing emotional from non-emotional memories.
- Adaptive Nature of Memory: The seven memory sins reflect the trade-offs for a memory system optimized for general accuracy and adaptability.
