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 developed to evaluate anhedonia and motivational deficits in major depressive disorder. In the brain, anhedonia is frequently linked to dysregulation in the Nucleus Accumbens (NAc) and the broader dopaminergic reward system. While neuroimaging has localized these deficits, establishing a causal link between NAc activity an
This research is emerging as AI models achieve increasingly complex cognitive abilities, prompting deeper inquiry into their internal reward mechanisms and alignment with human psychology.
Understanding reward valuation and anhedonia in VLM's is critical for building more robust, ethically aligned, and motivationally sophisticated AI, directly impacting their deployment in real-world scenarios.
The ability to mechanistically assess and potentially remediate 'anhedonia' in AI models could lead to systems that are more goal-directed, autonomous, and less prone to motivational deficits, blurring the lines between engineered and biological intelligence.
