Unconscious processing is a widely studied topic in the field of psychology. Continuous Flash Suppression (CFS) has become immensely popular to study this phenomenon. However, there is uncertainty in the ability of CFS to study high-level unconscious processing. Nevertheless, Jiang et al. (2006) were able to provide evidence for high-level unconscious processing with the use of CFS. They studied the influence of invisible erotic images on spatial attention, based on the sexual preference of the participants. These erotic images were rendered invisible with CFS. 

They found evidence that participants attention was shifted towards the erotic image of the preferred gender. The aim of this study was to replicate the Jiang et al. (2006) study with better methodological reasoning. Yet, this study provided no evidence for high-level unconscious processing and has therefore failed to replicate the study of Jiang et al. (2006). Because of the lack of homogeneous research towards CFS, there is a lot unknown about the ways in which CFS works best. Therefore, there are many factors that could have caused CFS to not work properly. Many other studies have also failed to replicate a study demonstrating evidence for high-level unconscious processing with the use of CFS. It is therefore important that homogeneous research is conducted to provide generalizable evidence for the right usages of CFS.
