The dynamic developmental theory of ADHD suggests that dopamine hypofunction produces a narrower time window for associating preceding stimuli, behavior, and its consequences, behaviorally described as a steeper and shorter delay-of-reinforcement gradient.
The dynamic developmental theory of ADHD suggests that reinforcement and extinction processes are altered in ADHD due to dopamine dysfunction, and suggests that the altered reinforcement processes behaviorally can be described as a steeper and shorter delay-of-reinforcement gradient in ADHD compared to normal controls.
But Cemetery Hill is now better known — and feared — as a steep, ankle-twisting obstacle on a 3.1-mile cross-country course that is as legendary for its difficulty as for its rugged beauty.

The onset of trench warfare after the first few months of World War I greatly increased the demand for howitzers, as they fired at a steep angle, and were thus better suited than guns at hitting targets in trenches.
The distributions for δ a / a in the left and δ a / f in both panels are remarkably narrow with a median error ∼ϵ as targeted, a steep truncation towards large errors, and a maximum error ∼ 10 ϵ.
