Description: This component contains the LiveCode source file (version 9.0.2) for presenting the sequences and materials to participants and collecting their responses. LiveCode’s Community Edition, is a free open source object-oriented, cross-platform, natural language rapid development environment that can be used for programming local (LiveCode) and web-based (HTML5) experiments. LiveCode is based on the Transcript programming language (a high-level xTalk scripting language like HyperCard’s HyperTalk), and is a great stepping stone to learning Javascript and Python. It is fit for developing experiments that require fine-grained control, complex sequencing, and heavy back-end processing. You can download LiveCode for PC, Linux or Mac at: https://downloads.livecode.com/livecode. You can run this experiment on your own computer by installing the appropriate version of LiveCode Community, and downloading the zip file. Note, however, that the “images” file is missing, which you’ll need for the experiment to run properly. As we describe in the Materials component, the fingerprint images we used in this project were sourced from the NIST Special Database 300 (https://www.nist.gov/itl/iad/image-group/nist-special-database-300), which consists of 8871 rolled fingerprints, which were donated to NIST by the Federal Bureau of Investigation. Unfortunately, NIST has not made this special database openly available, and we do not have permission to distribute it further, publish, copy, or disseminate it in any way or form whatsoever, whether for profit or not. If you’d like to access the images we used in this project, contact fingerprint_data@nist.gov to get permission from NIST to use the database (it’s freely available for biometrics related research, development, and education), forward Jason Tangen (uqjtange@uq.edu.au) the automated access email, and he’ll send you a link to the images we used in this project. Once you get the “images” folder, just put it inside the main experiment folder, which can be stored anywhere on your machine. But the file structure within this folder needs to be preserved to run the experiment, as the script is reading in the participant sequences, images, and instructions on the fly from the same location as the source file.
