Study Notes
Post-Decisional Processing
- The primary task described in the text is related to decision-making and confidence judgments.
EEG Signal
- The post-decisional EEG signal indicates the accumulation of evidence after a decision has been made.
Diffusion Process
- The diffusion process in post-decisional processing differs from the primary decision-making process in that it involves the accumulation of evidence after a decision has been made.
Experimental Design
- The experimental design used to gain control over post-decisional processing involves manipulating post-decision evidence to study its impact on confidence.
Bayesian Model
- According to the Bayesian model, confidence increases after correct decisions as post-decision evidence accumulates.
- Confidence decreases after incorrect decisions as post-decision evidence accumulates.
Confidence Estimates
- Confidence estimates can facilitate adaptive behavior by allowing individuals to adjust their decisions based on the strength of the evidence.
Drift-Diffusion Model (DDM)
- A limitation of the DDM approach to confidence is that it does not capture the separate computations involved in confidence judgments.
Evidence Accumulation
- Post-decisional evidence accumulation contributes to confidence judgments by providing additional information that can be used to evaluate the accuracy of a decision.
Decision Types
- The post-decisional extension of the DDM can capture a wide range of decisions, including sensory discrimination tasks.
Neural Basis of Confidence
- In the context of Macaque monkeys' training, confidence is informed by evidence accumulation signals in the brain.
- It is important to keep different computations separate when interpreting the neural basis of confidence to avoid confounding variables.
Sensory Information
- Sensory information influences decision-making by providing the initial evidence used to make a decision.
Decision Thresholds
- Decision thresholds play a crucial role in decision-making by determining the amount of evidence required to make a decision.
Error Recognition
- Confidence impacts error recognition by influencing how quickly and accurately individuals recognize and correct their mistakes.
Social Interactions
- Confidence levels can affect social interactions by influencing how individuals communicate and respond to others.
Methodologies
- Methodologies used to measure the accuracy and confidence in sensory discrimination tasks include behavioral and neuroimaging techniques.
Brain Regions
- Techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) are used to study the brain regions involved in confidence judgments.
