Study Notes
Prediction Error Learning
- Rescorla-Wagner Model is a model of associative learning.
- The model predicts reward based on prior experiences.
- Prediction error is the difference between expected and received reward.
- Learning occurs when prediction errors are present.
- Learning rate (αβ) is based on the salience of the conditioned stimulus (CS) and unconditioned stimulus (US)
- Learning is driven by surprise.
- Unexpected reward leads to a positive prediction error (+PE).
- Unexpected omission of reward leads to a negative prediction error (-PE).
- Salience of a stimuli affects how much attention a stimuli receives.
- Learning rate is adjusted by the salience of stimuli.
Attention and the Brain
- Attention is both an early processing module and a part of learning.
- Attention allows selective focus on stimuli.
- Salience adjusts learning rates, in reward prediction models.
- Endogenous attention is internally generated.
- Exogenous attention is externally generated.
- The parietal cortex plays a role in attention.
- Right parietal cortex activity is present when focusing on the left visual field.
- The right and left parietal cortices are both active when attending to locations in the left or right visual fields.
- Injury to the right parietal lobe can cause visual neglect of the left visual field.
- People with this injury may ignore the left aspect of their face when shaving or applying makeup.
Amygdala and Unexpected Punishment
- Unexpected punishment may also be considered a type of prediction error learning.
- Unexpected punishment impacts activity in the amygdala, measured by tissue oxygenation (TO2), which changes based on the timing of punishment (e.g. 1st time, 2nd time, 3rd time)
- The amygdala responds more to unexpected shocks than expected shocks.
- The amygdala can detect unpredictable events.
Dopamine and Reward Prediction Error
- Dopamine neurons report prediction errors in reward.
- Dopamine increases firing when an unexpected reward is received.
- Dopamine decreases firing when a predicted reward is omitted.
- The striatum is more active with immediate feedback in learning
- PD patients perform worse in learning tasks with immediate feedback.
- Parkinson's disease patients have issues with adapting to new contingencies.
Other Cognitive Processes
- The computational goal is what the brain system tries to accomplish in a cognitive system.
- An algorithm works to fulfill the computational goal within a cognitive system.
- Implementation is how nervous tissue implements the algorithm.
- The classic cognitive view is that behavior is controlled by separate mechanisms.
- The brain minimizes the difference between expectation and reality.
- This may present as behavior driven by prediction updates.
- Kamin's Blocking is a violation of stimulus association during learning.
- The Rescorla-Wagner model can explain blocking
