Group Polarization01:01

Group Polarization

35.3K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Framing Effects03:26

Framing Effects

7.5K
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...

Language and Cognition01:27

Language and Cognition

427
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Lateralization01:28

Lateralization

425
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

15.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Stereotype Content Model02:16

Stereotype Content Model

14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Summary

Media framing of COVID-19 influenced disgust sensitivity and language processing. Political ideology and individual disgust proneness interact with perceived safety, affecting how people respond to health information.

Area of Science:

  • Psychology
  • Cognitive Science
  • Social Psychology

Background:

  • Disgust is an adaptive emotion influencing disease avoidance.
  • Individual differences in disgust sensitivity exist and fluctuate with perceived environmental safety.
  • Previous research linked word processing to disgust sensitivity, not word disgust itself.

Purpose of the Study:

  • To investigate if media portrayal of COVID-19 dynamically alters disgust and subsequent language processing.
  • To examine the roles of political ideology and disgust proneness in these effects.

Main Methods:

  • Participants were exposed to COVID-19 news headlines (threat vs. downplayed).
  • Experiment 1: Word ratings for disgust and valence (N=83).
  • Experiment 2: Lexical decision task (N=86).

Main Results:

  • Headline type influenced word ratings but not lexical decisions.
  • Political ideology and disgust proneness affected both word ratings and reaction times.
  • Liberal participants showed higher disgust after threat downplaying; conservative participants showed higher disgust after threat emphasis.
  • Political ideology predicted reaction times more than disgust proneness.

Conclusions:

  • Disgust proneness and political ideology dynamically interact with perceived environmental safety, impacting language processing.
  • Media framing and political discourse surrounding health crises can modulate public disgust responses.
  • Understanding these interactions is crucial for public health communication strategies.
