Ébauche de première étude

General idea

The main goal of this research will be to partially reproduce the design proposed by Newman & colleagues (2012; 2018; 2020) used to test the Truthiness effect which is testing how images influence perceptions of truth (cf Newman & Schwarz, 2024).

Introduction

Semantically related contexts produce easier conceptual processing relative to neutral contexts, an experience that people may interpret as evidence of familiarity. Likewise, semantically priming, repeating, or retrieving related information can produce illusions of frequency, familiarity, and truth—presumably due to increased ease of retrieval or cognitive availabilit (Newman et al., 2015)

Example of Stimuli

Example of used sentences

Considered variables

Dependant variables

• Behavioral
  • C scores (Newman et al., 2012)
  • Proportion of "true" (Newman et al., 2018)
  • Likert scale: Croyance dans la headline (0-10) (Guo, S., Zhong & Hu, 2024)
• Physiological
  • Eye-tracking

Independant variables

• Image/no image : no photo items serve as a benchmark for processing by manipulating the presence of photos within and between-subjects. If the effect of photos depends on a comparison against a (no photo) standard, we should expect to see the most pronounced effects of photos in our within-subject designs (Newman et al., 2015)
• Type of image :
  • Semantically related (vs semantically not related)
  • Obviously AI generated (vs "real") : Les gens rapportent avoir une bonne capacité à distinguer une image IA d'une image réelle, mais les études sur le domaine montre que ce n'est pas le cas (Nightingale & Harid, 2021 in Newman & Schwarz, 2024)
  • Conspiracy Theory related (vs not related)
  • Picture (vs drawing)
  • Image quality : perceptual fluency and manipulations such as degraded images, difficult fonts, and low contrast colors that require people to invest more cognitive effort to make sense of stimuli, which in turn can bias people toward evaluating these stimuli more negatively the context of a truth judgment, additional cognitive effort might be taken as a signal that the information being evaluated is false. (Newman et al., 2015)

• Type of sentences relatde
  • Simple / hard (Newmann, et al., 2012)
