Decision Making01:20

Decision Making

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...
Routes of Persuasion02:20

Routes of Persuasion

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?
Reason and Intuition01:37

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
Decision Making: Traditional Method01:14

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...
Decision Making: P-value Method01:09

Decision Making: P-value Method

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the $2,000...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Decision Science

Background:

  • Individuals frequently seek expert advice for decision-making.
  • The neural underpinnings of how advice influences choices remain unclear.

Purpose of the Study:

  • To investigate the neural basis of how expert advice affects decision-making.
  • To understand how the brain processes and utilizes advice from varying expertise levels.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was employed.
  • Participants performed an estimation task while receiving expert and novice advice.
  • Behavioral data on advice valuation and utilization were collected.

Main Results:

  • Participants valued expert advice over novice advice, reflected in ventral striatum activity.
  • The "opinion difference" between personal and advisor's opinion influenced advice use, engaging reward-sensitive brain regions.
  • The left lateral orbitofrontal cortex integrated opinion difference and expertise, correlating with advice utilization.

Conclusions:

  • Neural activity in the ventral striatum tracks the valuation of expert advice.
  • Reward-related brain regions represent the comparison between personal opinion and advisor's input.
  • The lateral orbitofrontal cortex plays a key role in integrating expertise and opinion difference to guide advice utilization.
