LexTALE instruction

How to use LexTALE

 

LexTALE is a brief lexical decision test which can be used to measure English proficiency of non-native speakers. All booth computers have LexTALE programs. 

LexTALE can be downloaded from here: www.lextale.com

 

LexTALE script is slightly modified to change the formant of the experiment. Followings are different from the original version of LexTALE:

- Add subject name into the result file (modified "lextale.praat").

- Add "Experiment finished" message when the experiment ends (modified "lextale.txt"). 

 

 

Followings are the instruction to use LexTALE (from README_en.txt, downloaded from www.lextale.com).

- Open Praat (you need the version of July 2011 or newer; download from http://www.fon.hum.uva.nl/praat/).

- LexTALE scripts are normally located under "Desktop → Pre-Test → LexTALE_Praat_en"

- Go to "Read -> Read from file" and select "lextale.txt" (Experiment MFC style).

- In the "Objects" list, select "ExperimentMFC lextale" and click "Run" on the right side.

- The experiment will start, subjects use the mouse or the "n" (no) and "y" (yes) buttons on the keyboard to respond. 

- When the experiment is finished, there will be a message "Experiment finished" (Some computers will show a grey screen). Close it.

- Go to "Praat → Open Praat script" and select "lextale.praat"

- Make sure you have selected "ExperimentMFC lextale" in Praat window, and run the Praat script (press ctrl+R or click Run -> run).
