## Summary  
The paper investigates how AI assistance impacts human skill development by studying learning with logic puzzles under varying levels of on‑demand AI help. It contributes empirical evidence that frequent AI use, especially during the assistance phase, leads to poorer unassisted performance and overestimation of future ability. The study also reveals a relationship between independent reasoning effort and latent skill growth.

## Key Contributions  
- Finding 1: Lower‑cost AI assistance increases the frequency of AI requests.  
- Finding 2: Participants who rely on AI during the assistance phase perform worse afterward, and their later performance is overestimated when predicted from earlier assisted performance.  
- Finding 3: Greater independent problem‑solving effort correlates with larger gains in latent ability.

## Methodology  
The authors conducted a controlled experiment where participants completed logic puzzles in three phases—pre‑AI, AI‑access, and post‑AI. They varied the cost of requesting AI help to manipulate usage frequency. Using a Bayesian latent ability model, they estimated individual initial ability, skill after assistance, and changes over time while accounting for participant‑specific factors.

## Results  
Lower‑cost assistance led to more frequent AI requests. Post‑assistance performance was lower than pre‑assistance, especially when participants had relied on AI during the assistance phase. The Bayesian model showed that those who solved problems independently after assistance showed larger latent ability increases, indicating skill development is weaker with AI substitution.

## Significance  
This research provides evidence that while AI can boost short‑term performance, it may hinder long‑term skill acquisition by reducing independent reasoning practice, offering important insights for designing human‑AI collaboration in education and training.
