Abstract images and words can convey the same meaning

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Deriving meaning from abstract images is typically considered a subjective human experience.
• Previous research has primarily focused on concrete images for semantic priming studies.

Purpose of the Study:

• To investigate whether abstract images, despite lacking universal lexical associations, can elicit consistent meanings across observers.
• To examine the behavioral and neural correlates of semantic priming for abstract images.

Main Methods:

• A preliminary norming procedure was used to establish relatedness between abstract images and words.
• Naïve participants were presented with related and unrelated abstract picture-word pairs.
• Reaction time priming effects and event-related potentials (N400 amplitude) were measured.

Main Results:

• Participants showed a significant reaction time priming effect for related abstract picture-word pairs compared to unrelated ones.
• A decrease in N400 mean amplitude, indicative of semantic priming, was observed for related pairs.
• Both behavioral priming and neural measures correlated with the degree of relatedness established in the norming phase.

Conclusions:

• Abstract images can evoke consistent meanings across individuals, challenging the notion of purely idiosyncratic interpretation.
• The findings demonstrate that semantic processing of abstract visuals is robust and consistent, comparable to that of concrete stimuli.
• This suggests a shared capacity for deriving meaning from abstract visual information, akin to responses to music.
