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.
