Modelling Emotional Memory in Children with Tensor Networks

Summary

This research demonstrates how emotional valence influences the order-dependent structure of children's recognition memory. Correct recall of a sequence of emotionally-valenced toys depended not only on the valence of the toy itself but also on the valence of toys shown before and after it. While standard psychological models show low accuracy, a classical tensor network model incorporating valence achieves 77.98% accuracy, highlighting the value of quantum-inspired methods for modelling order-dependent phenomena like emotional memory. The study also introduces a novel protocol for exploring emotional temporal memory in children.

Abstract:We demonstrate how emotional valence influences the order-dependent structure of children's recognition memory: correct recall of a sequence of emotionally-valenced toys depended not just on the valence of a given toy itself, but also on the valence of the toys shown before and after it. Whilst standard psychological models confirm that order-dependence differs across an event (a set of toys shown in sequence), accuracy is low and the model does not reflect how memory for an emotional object influences others in the set. A classical tensor network model factoring in valence is able to achieve a 77.98\% accuracy in modelling the results of the study. While not strictly a ``quantum cognition'' model, this massive increase in accuracy shows the value of quantum-inspired methods for modelling order-dependent phenomena, such as emotional memory. Further, the task protocol we introduce presents a novel, real-world tool for exploring emotional temporal memory in children for analysis using classical and quantum-like models of cognition.

Key points

  • Emotional valence affects the recall order of sequential memories in children, influenced by both the current item and its neighbors.
  • Standard psychological models have low accuracy and fail to capture how emotional objects influence memory for others in the set.
  • A classical tensor network model incorporating valence achieves 77.98% accuracy, a significant improvement.
  • The new protocol provides a real-world tool for analyzing children's emotional temporal memory using classical and quantum-like cognitive models.
