Overview

Randomized trial validates 3D objects for emotion elicitation in adults, suggesting improved emotional assessments.

Key Points

  • This research aims to validate a database of 3D objects designed to elicit emotions, enhancing ecological validity in emotional perception studies.
  • Created the Emotional Daily Life Library (E-DLL) with 132 3D objects.
  • Measured emotional ratings (valence, arousal, dominance) and personality traits in 52 adults.
  • Utilized Cumulative Link Mixed Models and Generalized Linear Mixed Models for data analysis.
  • Valence ratings negatively influenced by the interaction of neuroticism and depressive symptoms.
  • Higher neuroticism and conscientiousness showed marginal positive associations with arousal ratings.
  • Emotional attributions driven by object properties and personality traits predicted negative emotions significantly.
