Fidgeting

[1][2] Fidgeting may involve playing with one's fingers,[3] hair, or personal objects (e.g. glasses, pens or items of clothing).

Fidgeting is commonly used as a label for unexplained or subconscious activities and postural movements that people perform while seated or standing idle.

[7][better source needed] When interested in a task, a seated person will suppress their fidgeting,[8] a process described as Non-Instrumental Movement Inhibition (NIMI).

Some education researchers consider fidgeting, along with noise-making, as clear signs of inattention or low lecture quality,[9] although educators point out that active engagement can take place without constantly directing attention to the instructor (i.e., engagement and attention are related but not equivalent[8]).

These "fidget toys" are typically intended to help students with autism or ADHD focus better,[21][22] and come with a variety of buttons and switches that can be played with by the user.
