LLMs exhibit congruency effects similar to human cognition in conflict tasks

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel verbal conflict task to investigate congruency effects in large language models, drawing parallels to psychological and neuroscience studies. The task involves prompts that elicit a default completion, with explicit rules either agreeing or conflicting with this default. Analysis of models like Gemma-2-2B and various Pythia versions revealed strong default tendencies and significant congruency effects, attributed to competition between in-weight default mappings and in-context rule-based mappings. The study utilized causal attribution, attention analysis, and ablations to identify distinct processing pathways activated by superficial cues versus explicit rules. AI

IMPACT Provides a new framework for analyzing internal model mechanisms and competition between learned mappings.

    Conflict and Congruency Effects in Large Language Models: In-Weight and In-Context Competition in a Verbal Conflict Task

    arXiv:2608.11510v1 Announce Type: cross Abstract: Congruency effects, observed in conflict tasks such as Stroop and flanker tasks, have been investigated for nearly a century in psychology and neuroscience, but their mechanistic basis is not fully understood. We introduce a verba…
