===Pursuit rotor task===

A device used to study visual-motor tracking skills and [[hand–eye coordination]] by requiring the participant to follow a moving object with a [[cursor (computers)|cursor]]<ref name="Cognitive Atlas">{{Cite web | url=http://www.cognitiveatlas.org | title=Cognitive Atlas}}</ref> or use a [[stylus]] to follow the target on a computer screen or a turntable.<ref>{{cite web |url=http://149.142.158.188/phenowiki/wiki/index.php/Pursuit_Rotor_Task |title=ArchivedPursuit copyRotor Task - Phenowiki |access-date=27 February 2012 |url-status=dead |archive-url=https://web.archive.org/web/20130927220537/http://149.142.158.188/phenowiki/wiki/index.php/Pursuit_Rotor_Task |archive-date=27 September 2013 }}</ref> With the computer screen version, the participant follows a dot on a circular path like the one shown below.<ref>{{Cite web | url=http://peblblog.blogspot.com/2010/04/pursuit-rotor-task.html | title=PEBL Blog: The Pursuit Rotor Task| date=24 April 2010}}</ref> [[File:PursuitRotor.png|thumb|Screenshot of a computerized version of the pursuit rotor task.]]

The pursuit rotor task is a simple pure visual-motor tracking test that has consistent results within age groups.<ref name="Lang">{{cite journal | doi=10.1016/0191-8869(81)90025-8 | volume=2 | issue=3 | title=Learning and reminiscence in the pursuit rotor performance of normal and depressed subjects | journal=Personality and Individual Differences | pages=207–213 | year=1981 | last1 = Lang | first1 = Rudie J.}}</ref> This displays a measurement of procedural memory as well as demonstrates the participant's [[fine motor skill]]s. The pursuit rotor task tests the fine-motor skills which are controlled by the motor cortex illustrated by the green section below.

Amnesic participants show no impairment in this motor task when tested at later trials. It does however seem to be affected by lack of sleep and drug use.<ref name="Dotto">{{cite journal | last1 = Dotto | first1 = L | year = 1996 | title = Sleep Stages, Memory and Learning | journal = Canadian Medical Association Journal | volume = 154 | issue = 8| pages = 1193–6 | pmid = 8612256 | pmc = 1487644 }}</ref>
