Semantic Category

Required Experiment Builder Version: 1.4.624 or higher
EyeLink Required: No
Type: Complete Example
Difficulty Level: Moderate

This example illustrates:
  • How to use Custom Class to handle the 60 variables in the editor text boxes on screen
  • How to use of Keyboard triggers to receive number inputs
  • How to use of Timer node to set a blinking text cursor position
Description:

This experiment is an implementation based on Experiment 1 of the following paper:
  • Rosch, E. (1975). Cognitive Representations of Semantic Categories, Journal of Experimental Psychology: General, 104(3), 92-233.
There are totally 10 blocks of experiment, each block corresponding to a category of up to 60 nouns. This project illustrates how to make it possible to enter numbers into edit boxes and manipulate cursor on the screen. Complete understanding of it requires knowledge of Python.

The Semantic_Category_Random.ebz is a slight modification of the above experiment. It differs from the experiment of the paper in that every participant received a different, random order of instances under the category name and shows how to randomize up to 60 columns of the Data Source through the Custom class, as well as how to handling variable number of Data Source columns (varying from 50, 51, 54, 55, 56, 59 to 60 ones).

**Additional detailed information about the project is given in the notes section for most nodes. To see notes for a given node, either mouse over that node or click on it to display the notes window. If the notes window is not visible, go to the "View" drop down menu in Experiment Builder, select "Properties", and check "Note".

Instructions:
  1. Download the Semantic_Category_Paper.ebz or Semantic_Category_Random.ebz example from this message.
  2. Launch the Experiment Builder application.
  3. Unpack the Semantic_Category_Paper.ebz or Semantic_Category_Random.ebz file to a location on your Experiment Builder PC with "File menu -> Unpack".
  4. Open the project in Experiment Builder.
  5. Deploy the project to a new folder.
  6. Run the Semantic_Category_Paper.exe or Semantic_Category_Random.exe from the deployed directory.
