Dynamic competition and binding of concepts through time and space

Area of Science:

• Cognitive Psychology
• Social Psychology
• Computational Neuroscience

Background:

• Existing models of implicit stereotypes often rely on abstract conceptual oppositions.
• These models struggle to fully explain response time differences observed in the Implicit Association Test (IAT).

Purpose of the Study:

• To introduce and test alternative models of implicit stereotypes that leverage sensorimotor dimensions.
• To account for the opposition between concepts based on spatial mapping and response actions in the IAT.
• To investigate the dynamic characteristics of decision-making processes in stereotype formation.

Main Methods:

• Development of computational models based on sensorimotor mappings within the IAT.
• Utilizing a mouse-tracking adapted IAT procedure to capture fine-grained movement data.
• Comparing model predictions with human behavioral data.

Main Results:

• Sensorimotor models naturally account for conceptual oppositions inherent in IAT task designs.
• These models successfully predict the emergence of the IAT effect.
• Analysis of mouse-tracking data reveals dynamic decision-making characteristics consistent with sensorimotor accounts.

Conclusions:

• Sensorimotor dimensions offer a more dynamic and explanatory framework for implicit stereotype models.
• The findings challenge abstract-dimensional models and highlight the role of embodied cognition in implicit bias.
• Mouse-tracking provides valuable insights into the continuous, dynamic nature of cognitive processes underlying the IAT.
