Hindsight Biases

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Prediction Intervals

Prediction Intervals

The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Propagation of Uncertainty from Random Error

Propagation of Uncertainty from Random Error

An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Propagation of Uncertainty from Systematic Error

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Random and Systematic Errors

Random and Systematic Errors

Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Area of Science:

Neuroscience
Cognitive Science
Computational Neuroscience

Background:

Surprise is a key driver of learning.
Neural signals like reward prediction error (RPE) and state prediction error (SPE) are thought to mediate surprise-based reinforcement learning.

Purpose of the Study:

To identify and characterize a novel neural surprise signal.
To differentiate this signal from established RPE and SPE signals in reinforcement learning.

Main Methods:

Measured neural surprise responses while controlling for RPE.
Accounted for potential confounds related to SPE.
Utilized neuroimaging techniques to identify brain regions involved.

Main Results:

A novel surprise signal was identified.
This signal was distinct from both unsigned and signed RPE and SPE.
The signal was observed in the ventral striatum, primary sensory cortex, frontal poles, and amygdala.

Conclusions:

A new neural signal for surprise in reinforcement learning has been discovered.
This finding expands our understanding of the neural mechanisms underlying learning and decision-making.
The identified signal offers a new target for studying surprise and its role in various cognitive functions.
