Lexical Decision (Web-)App I want to make a lexical decision experiment, is there any freely available software for this? A Javascript-based webapp would suit me best, as it would run in the browser without the need to install anything.
One option is to use Inquisit Web Edition.
 Here is an example script with a lexical decision task.

Unfortunately, it is not free and it requires installation of a plug-in. 

Version 4 of Inquisit runs on OSX and Windows. Thus, it wont work in Linux or on phones, tablets, etc.
