Cognitive Processing of Cryptography Concepts – Spring 2018

I am researching how cryptography concepts are processed in the brain, and would like you to participate an experiment designed to provide insight into that question. I am seeking no more than 30 participants and will compensate each participant up to $275.00 each. The experiment will run during the Spring 2018 academic term at Purdue University and will require that you:


o Complete an online pre-test consisting of 50 multiple choice questions designed to sample subjects’ understanding of the cryptography concepts being taught during this experiment. (Prior to January 15, 2018)


o Complete four online modules, each designed to instruct subjects in a particular cryptography concept, and each lasting no longer than 45 minutes. The modules must be completed in the order in which they are assigned to you. You will be given two weeks to complete each module. All modules are to be completed by March 17, 2018.


o Following the completion of the four online instructional modules, you will be required to complete a 50 question multiple choice posttest designed to measure subjects’ understanding of cryptographic concepts taught using the four online modules. You will be required to complete the posttest by April 21, 2018.


o You will also be required to complete a 1-hour fMRI scan during which they will be asked to answer questions about the cryptographic concepts taught during the four online instructional modules. In preparation for the scan, each subject will be given an fMRI safety tutorial and a self-screening health questionnaire. Because you will be subjected to MRI in this experiment, you are NOT ELIGIBLE TO PARTICIPATE IF YOU HAVE METAL (SUCH AS A STRUCTURAL PLATE OR PERMANENTLY ATTACHED RETAINER) IN YOUR HEAD. You MAY also be ineligible to participate if you:

have a cardiac pacemaker have any type of prosthesis (eye)
have an implanted cardiac defibrillator have a heart valve prosthesis/stents
have an aneurism clip have a shunt (spinal/intraventricular)
have a neuro or bone stimulator have wire sutures or surgical staples
have an insulin or infusion pump have bone/joint pin, screw, nail, plate
have an implanted drug infusion device have body tattoos
have a cochlear, otologic or ear implant have tattooed makeup (eyeliner, lip, etc.)
have prostate radiation seeds have breast tissue expander
have an IUD (intrauterine device) have hearing aids
have a transdermal (Nitro) medicine patch have body piercing(s)
have any metallic implants or objects have claustrophobia (fear of closed places)
have had an eye injury involving metallic objects such as metallic slivers or foreign bodies
have ever had surgery or any similarly invasive procedure
are or could be pregnant

For your participation in this experiment and complete all tasks in this experiment, you will be paid $275.00 in total. Specifically, subjects will be paid:
o $25.00 for completion of the pre-test, for the completion of each instructional module, and for the posttest. (total: $150.00)
o $25.00 for completion of the fMRI safety tutorial and health self-screening questionnaire.
o $50.00 for completion of the fMRI scan.
o $50.00 for completion of all tasks in this study.
If you do not complete all modules, you will be paid using the scale above for the components that you did complete. You may withdraw from the study at any time. Failure to complete the tasks in order and under the assigned timeline will result in withdraw from the study
If you would like to participate in this experiment or would like further information, please contact me via e-mail at beckmanj@purdue.edu. Participation will be granted on a first-come, first-serve basis.

Thank you for your consideration.
