The evidence for subliminal priming is overwhelming, drawing all the more importance to the possible implications. Although the overall effectiveness of the visual subliminal priming process is well demonstrated, the processing power and scope of the unconscious is less explored. For instance, how much visual complexity can be processed and stored per each visual primer? Visual images can come in varying levels of complexity raising questions about the processing power of the unconscious mind. Almost certainly, we will find some variability between individuals in processing power. If processing power was to be tested in a quantifiable way, we could compare each individual’s subliminal processing ability to working memory capacity which could provide an interesting way of looking at the relationship between memory forms and the correlations between them. Inability to internalize subliminal stimuli could be due to a few reasons. One reason is a problem in stimuli intake. In this case, dealing with the visual system we should look at the effectiveness of subliminal primers when they are presented in different areas of the visual field. Another problem could be an overload of the memory system occupied by subliminal primers. In an experimental setting, steadily increasing the complexity of the visual primers and testing to see if they had an effect would allow us greater insight into the subliminal processing capacity of the brain.
