Decision Making: P-value Method01:09

Decision Making: P-value Method

5.8K
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...

Decision Making01:20

Decision Making

1.1K
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...

Decision Making: Traditional Method

4.4K
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...

The Representativeness Heuristic02:13

The Representativeness Heuristic

15.4K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Reason and Intuition01:37

Reason and Intuition

5.9K
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...

Framing Effects03:26

Framing Effects

7.8K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Decision Science

Background:

  • Intertemporal choice, the capacity to forgo immediate rewards for future benefits, is fundamental to human behavior.
  • Neural mechanisms underlying the subjective valuation and comparison of immediate versus delayed rewards are not fully understood.

Purpose of the Study:

  • To investigate the neural representation and comparison of subjective values for immediate and delayed rewards during intertemporal decision-making.
  • To elucidate the brain regions involved in processing and comparing reward options with different temporal delays.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was employed during an intertemporal decision task.
  • Simultaneous and independent manipulation of immediate and delayed reward magnitudes.
  • Univariate analysis and multiple voxel pattern analysis were utilized to analyze brain activity.

Main Results:

  • Posterior dorsal medial prefrontal cortex (DmPFC) activity correlated with immediate reward value.
  • Anterior DmPFC activity correlated with delayed reward value.
  • Ventral medial prefrontal cortex (vmPFC) activity positively correlated with relative reward value, while dorsal anterior cingulate cortex (dACC) activity negatively correlated.

Conclusions:

  • Immediate and delayed rewards are neurally represented in distinct subregions of the DmPFC.
  • Reward comparison and decision-making are supported by interactions involving vmPFC and dACC.
  • Findings suggest a neural basis for the human capacity for delayed gratification.
