AI models show human-like anhedonia when reward valuation circuits are perturbed

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework to assess reward valuation in vision-language models, drawing parallels to human anhedonia and motivational deficits. By adapting clinical tests used for major depressive disorder, they identified and perturbed reward-anticipatory units within these AI models. The study found that disrupting these units led the models to favor low-effort, low-reward choices, mimicking symptoms of anhedonia without impairing general task capability. This work reveals functional reward valuation circuits in AI that closely mirror those observed in humans. AI

IMPACT This research could lead to AI systems that better understand and respond to human emotional and motivational states, potentially improving human-AI interaction and therapeutic applications.

    Reward Valuation in Vision Language Models: Causal Mechanisms Underlying Anhedonia

    arXiv:2607.06626v1 Announce Type: new Abstract: Recent Vision-Language Models capture increasingly complex aspects of human cognition. Here we ask whether this alignment extends to reward valuation, which we assess in a mechanistic framework built on clinical tests that were deve…
