Using a reference-dependent model based on Prospect Theory (PT), we reveal a functional asymmetry: More neurons encoded potential gains than losses, and gain-related signals were more tightly aligned with choices. This highlights a bias toward positive, goal-relevant outcomes in dACC value coding.
162
Demetrio Ferro @d-ferro.bsky.social · 28/07/2026
The core novelty of our model stands in the definition of a Prospect Theory (Kahneman & Tversky 1979) inspired reference r(ATC) that dynamically models the utility u(v,ATC) as the comparison of alternative offers for ATC<3 🤑 (r(ATC)→0) and of offer value to missing tokens (r(ATC)→6-ATC) for ATC≥3 😬.
152
Demetrio Ferro @d-ferro.bsky.social · 28/07/2026
Even when explicitly modeling interactions between value and token accumulation, neural encoding remained primarily driven by value signals. However, these signals were subtly reshaped across the task, suggesting that token accumulation modulates, but does not simply scale, value representations.
152
Demetrio Ferro @d-ferro.bsky.social · 28/07/2026
At the neural level we found that dorsal anterior cingulate cortex (dACC) encodes subjective value (SV) and ATC. SV-related signals peak during offer presentation, while ATC signals are sustained across the task, indicating progress monitoring. SV- but not ATC-related signals correlate with choices.
162
Demetrio Ferro @d-ferro.bsky.social · 28/07/2026
Importantly, this change followed a structured pattern: risk-taking attitude 🤑 increased early on (ATC<3), peaked around ATC=3, and decreased 😬 near jackpot (ATC≥3). This inverse-u profile clearly outlines that choices are guided by a shifting internal reference point tied to progress toward reward.
142
Demetrio Ferro @d-ferro.bsky.social · 28/07/2026
Accumulating tokens also reshapes risk preferences. Subjects are more risk-seeking when far from the jackpot, but became increasingly risk-averse as they approached it, especially when decisions were easier. This reveals a dynamic shift in strategy as ATC increases ↗️ and the goal becomes attainable.
132
Demetrio Ferro @d-ferro.bsky.social · 28/07/2026
Looking more closely, a clear pattern emerges: errors (i.e.,best choice misses) decrease as ATC increases, particularly when choices were not so trivial 🎰 (A). This improvement was most prominent at intermediate difficulty, indicating improved ability to discriminate between competing options 🧐 (B).
142
Demetrio Ferro @d-ferro.bsky.social · 28/07/2026
Analyzing behavior, we find that difference in Expected Value (EV), Mean EV (MEV), offer risk level (ORL), ATC and jackpot on previous trial (JPT) consistently influence choices (A). Strikingly, we find that ATC concurrently increases the speed ⏱️ AND accuracy ✅ of subject's choice reports 👀 (B-E).
141
Demetrio Ferro @d-ferro.bsky.social · 28/07/2026
We adopted a task where risky decisions don’t pay off immediately, but deliver virtual tokens 🪙 to collect across trials. Hitting accumulated tokens count (ATC) = 6 leads to a jackpot reward delivery 💰, and ATC reset. Leading question: do decision strategies depend on such dynamic ATC reference?
