Fundamental Attribution Error01:14

Fundamental Attribution Error

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Association Areas of the Cortex01:21

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
Random and Systematic Errors01:20

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
  • Decision Science
  • Computational Neuroscience

Background:

  • Risk is crucial for economic decisions, influencing subjective reward value.
  • Accurate, up-to-date risk information is essential for informed choices.
  • Environmental risk levels change dynamically, necessitating continuous risk information updating.

Purpose of the Study:

  • To investigate the neural mechanisms underlying the updating of dynamic risk information.
  • To identify brain regions and neuronal activity involved in processing risk prediction errors.

Main Methods:

  • Monkeys were presented with visual stimuli indicating varying risk levels.
  • Stimuli deviated from an initial common risk prediction.
  • Neuronal activity in the orbitofrontal cortex was recorded.

Main Results:

  • A subset of orbitofrontal neurons exhibited activity correlating with the difference between current and predicted risk.
  • This neuronal signal reflected risk prediction errors.

Conclusions:

  • Orbitofrontal cortex neurons play a role in encoding and updating risk information.
  • Neuronal signals tracking risk prediction errors may facilitate adaptive decision-making in changing environments.
