Article Synopsis
- The study compares the effects of Levodopa (L) and subthalamic deep brain stimulation (STN-DBS) on cost-valuation in Parkinson's disease, specifically focusing on axial movements (vowel production) versus distal movements (hand squeezing).
- Results indicate that STN-DBS makes vowel production easier while it complicates performance when combined with L.
- The findings suggest that treatment effects on axial and distal movements can differ significantly, impacting patients' quality of life and impulsivity assessments.
Effort Allocation in Children With ADHD: Abnormal Decision-Making or Poor Execution?

Effort allocation is a multi-faceted process driving both the decision to choose a high effort-high reward alternative over a low effort-low reward alternative, and the execution of this decision by recruiting sufficient effort. The objectives of our study were to examine whether children with ADHD would (a) show different reward-effort cost trade-off, and (b) have difficulty executing their decision. 50 children, aged 9 to 15, with and without ADHD, had to choose between high effort-high reward and low effort-low reward alternatives using a handheld dynamometer and to execute their choice.
