Editing Morris water navigation task (section)

The earliest measure of learning is ''[[Latency (engineering)|escape latency]]'', which is the time it takes to find the platform. However, this measure is confounded by swimming speed, not necessarily a cognitive factor, and path length between point of origin and platform is a parameter more closely related to spatial learning.<ref name=Wolfer /> Further parameters are the Gallagher measure,<ref>{{cite journal |vauthors=Maei HR, Zaslavsky K, Teixeira CM, Frankland PW |title=What is the Most Sensitive Measure of Water Maze Probe Test Performance? |journal=Front Integr Neurosci |volume=3 |pages=4 |year=2009 |pmid=19404412 |pmc=2659169 |doi=10.3389/neuro.07.004.2009 |doi-access=free }}</ref> the average distance to the platform, and the Whishaw corridor test,<ref name="Whishaw1985">{{cite journal |last1=Whishaw |first1=IQ |title=Cholinergic receptor blockade in the rat impairs locale but not taxon strategies for place navigation in a swimming pool. |journal=Behavioral Neuroscience |date=Oct 1985 |volume=99 |issue=5 |pages=979–1005 |pmid=3843314 |doi=10.1037/0735-7044.99.5.979 }}</ref> which measures time and path in a strip directly leading from swim-start to platform. Other parameters are measured during probe trials: the escape platform is removed and the mice or rats are allowed to search for it for a fixed time (often 60 seconds). Variables measured are time and path length in quadrants, time near platform, and platform crossings.
