We discussed lexical access, and how a lexical decision task can be a useful method for understanding lexical access.

This assignment covers 1) material creation and 2) experimental setup.

For 2), you will set up an experiment for a lexical decision task (which targets semantic and phonological priming effects) using PCIbex.

For 1), you will manually create new experimental materials.

Experimental material

material-worksheet.csv

This .csv file is a worksheet (hence some of the rows are missing) that contains experimental design and materials for the lexical decision task.

Experiment setup

pcibex-1.zip

This file contains files used for setting up the a lexical decision task on PCIbex.

</aside>

Download and unzip the file. Go to the data_includes folder, and you will find main.js in it.

For editing this javascript file, you can i) either use the PCIbex editor, or ii) use a text editor to work on the file. I personally use a text editor (called Visual Studio Code) since it tells me missing brackets or dots that are crucial for running the code. PCIbex editor is sometimes a bit slow in updating changes, so if you’re using the PCIbex’s built-in editor, make sure all the changes you have made are saved before leaving the page or running the experiment.
