HAB

Run an auditory Habituation (HAB) study in Matlab with minimal configuration. Uses a checkerboard to engage the infant while listening to alternating or non-alternating sounds.

How to use HAB

Download HAB

Download hab and the example "pdisc" study folder
Create a folder in your Matlab directory and place these files inside of it
Add this folder to your list of Matlab paths

Create a new study

Copy the example study folder, "pdisc", into a subfolder of your main HAB directory
Modify config.txt with the configuration options for the new study
Modify the stimuli in the stimuli sub-folder.

Run a session

Load Matlab
Type hab in the command prompt
Select your new study folder and click "Open"
Follow on-screen prompts (e.g., enter the experimenter's name, infant's subject code, age, etc.)
Code the infant's looking using the DownArrow (for a center look).
A log for the session will be created in the logs sub-folder
A session file (with looking time results, participant details, and session metadata) will be created in the sessions sub-folder
