Framing Effects03:26

Framing Effects

7.7K
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...

Reason and Intuition01:37

Reason and Intuition

7.1K
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...

Decision Making01:20

Decision Making

410
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

4.7K
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...

Self-Regulation01:25

Self-Regulation

98
Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

93
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Summary

Escalation decisions involve distinct brain networks compared to de-escalation. Decision framing and self-responsibility significantly influence these neural pathways, impacting commitment bias.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Decision Science

Background:

  • Escalation of commitment represents a pervasive bias in human decision-making.
  • Understanding the neural underpinnings of this bias is crucial for identifying its modulators.

Purpose of the Study:

  • To investigate the neural differences between escalation and de-escalation decisions.
  • To examine how self-responsibility and outcome framing influence these neural activations.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was employed with 29 participants.
  • Whole-brain and region-of-interest (ROI) analyses were conducted.
  • Mediation analysis explored the role of neural activations in decision-making.

Main Results:

  • Escalation decisions were faster than de-escalation decisions.
  • Distinct brain networks were identified for escalation (anterior cingulate cortex, insula, precuneus) and de-escalation (inferior and superior frontal gyri).
  • Positive framing increased activation in escalation-related regions; negative framing increased activation in de-escalation regions.

Conclusions:

  • Neural recruitment differs significantly between escalation and de-escalation.
  • Framing and responsibility modulate these neural processes, influencing commitment bias.
  • The findings offer insights into the neural basis of decision-making biases.
