**Introduction** This is part of the Collaborative Research and Education Program (CREP) and is a replication study on Kool, W., McGuire, J. T., Rosen, Z. B., & Botvinick, M. M. (2010). Decision making and the avoidance of cognitive demand. *Journal of Experimental Psychology: General*, 139(4), 665. This replication study was conducted by a team of undergraduate student researchers from Brigham Young University-Idaho. The researchers are Trevor Joy, Pahoran Marquez, Brandi Nessen, Robert Parker, Chad Schaeffer, and Mark Schmidt under the supervision of Brady Wiggins, PhD. <br> **Summary of Original Study** This study was motivated by the theory that humans are most likely to choose the least demanding ideal behavior available to them. There is sufficient evidence that this principle holds in cases of physical demand. The purpose of the original study and this replication is to discover if the same principle applies to cognitive demand. Six experiments were conducted, as to ensure causation of the independent variable. The results of each experiment supported the hypothesis that people prefer low cognitive demand tasks to high. ***The Replication*** We replicated the third experiment from the initial series of six. While the original data consisted of 37 students from Princeton, our data consists of 37 BYUI students, recruited from undergraduate general psychology classes. The Psychophysics Toolbox extensions for Matlab (Brainard, 1997; Pelli, 1997) was our platform for testing task selection. <br/> [1]: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2970648/ [2]: https://osf.io/53eup/ "FAQ about MatLab"
