Importantly, though increases in task difficulty may increase learning potential, increased task difficulty is also expected to decrease performance. Thus, an optimal challenge point exists when learning is maximized and detriment to performance in practice is minimized.
Some researchers include a metacognitive component in their definition. In this view, the Dunning–Kruger effect is the thesis that those who are incompetent in a given area tend to be ignorant of their incompetence, i.e., they lack the metacognitive ability to become aware of their incompetence.
Other theories and models of arousal do not affirm the Hebb or Yerkes-Dodson curve. The widely supported theory of optimal flow presents a less simplistic understanding of arousal and skill-level match. Reversal theory actively opposes the Yerkes-Dodson law by demonstrating how the psyche operates on the principle bistability rather than ...
Another approach is through the difficulty curve of the game, making enemies stronger as the player-characters advance deeper into the game, and requiring the player to spend time to improve the character whether through new gear, abilities, or the player's own performance to progress.
The Bell Curve: Intelligence and Class Structure in American Life is a 1994 book by the psychologist Richard J.

President-elect Trump’s first sit-down interview since winning a second White House term aired Sunday, giving the public a view into his mindset as he prepares to return to office. Trump spoke ...
An undirected graph G and a few example cuts with the corresponding conductances. In theoretical computer science, graph theory, and mathematics, the conductance is a parameter of a Markov chain that is closely tied to its mixing time, that is, how rapidly the chain converges to its stationary distribution, should it exist.
