Study Notes
Learning and Memory Constructs
- Learning and memory are theoretical constructs that explain past experiences' influence on behavior.
- Observable experiences lead to inferred psychological states, culminating in observable behavior.
- Example: Yawning indicates tiredness; smiling indicates happiness.
Definitions and Concepts
- Learning is a lasting behavioral change due to environmental experiences.
- Latent learning occurs without immediate behavioral expression or reinforcement, becoming evident later.
- Memory involves forming, storing, and retrieving records of past experiences.
Key Views on Learning and Memory
- Squire's definition differentiates learning (acquisition of new information) from memory (persistence of that information for future recall).
Experimental Approaches
- Psychological Approach: Examines experience leading to behavioral changes through inference.
- Neurobiological Approach: Explores brain areas, cellular structures, and molecular processes involved in learning and memory.
Cellular Level Approach
- Neurons are nervous system's basic units consisting of soma (cell bodies), dendrites (receivers), and axons (senders).
- Law of dynamic polarization describes the flow of neuronal activity from dendrites to axons at synapses.
Synaptic Plasticity Hypothesis
- Synaptic changes represent the neurobiological basis for learning and memory.
- The question arises about understanding biology without observing behavior.
Systems Level Approach
- Investigates specific brain regions' functions through physical or chemical damage, assessing changes in behavior.
- Broca’s area lesions result in speech production deficits.
Ribot's Law
- Older memories are generally more resistant to disruption than newer ones (e.g., recent memories are least resistant, while emotional memories are most resistant).
Consolidation Theory & Memory Stages
- Memory progression from sensory experiences (after image) to active recall (STM, WM), and then to secondary memory (LTM).
Ebbinghaus and Memory Research
- Ebbinghaus studied "pure memory" using nonsense syllables, founding experimental psychology.
- The forgetting curve illustrates memory retention drops sharply after one hour post-learning but stabilizes thereafter.
Memory Trace Dynamics
- Short-term memory traces decay quickly and are vulnerable, while long-term memory traces decay slowly and are more resilient.
Multiple Memory System Perspective
- Considers different memory types: personal facts, emotions, and skills.
Experimental Testing Framework
- Hypothesis formation, prediction, experimental design, data analysis, and interpretation are essential stages in experimental research.
Influences on Behavior Beyond Memory
- Factors: Sensory, attentional, perceptual, motivational, emotional, motor, biological influences may affect behavior independently of memory.
Engram Concept
- Engram refers to the hypothetical permanent brain change that accounts for memory existence.
Lashley’s Hypothesis
- Proposed that the engram resides in the cortex, with memory impairments related to lesion size rather than specific location.
- Introduced the theory of equipotentiality, suggesting all cortical areas contribute to learning and memory.
Neuroscience Research Methods
- Techniques include lesion studies, brain imaging, neuropharmacology, genetic engineering, viral vector usage, and optogenetics.
Memory Consolidation
- Involves the transformation of memory representation into a permanent form, transitioning from short-term to long-term memory.
Memory Disruption and Amnesia
- Memory disruption includes storage (permanent failure) and retrieval (temporary amnesia) failures.
- Amnesia types:
- Retrograde (loss of recent memory before trauma) allows retention of older memories.
- Anterograde (inability to form new memories post-trauma).
