Research to determine what subliminal presentation accomplishes and its effects upon the learning process is very limited. The possibility of presenting subliminal information in a passive manner to reinforce the learning process and the possibility that this presentation can aid in the absorption of the information needed to learn is examined. A previous study examined this possibility using a text editor as the test instrument. In this thesis, a direct manipulation interface using a spreadsheet which visually presents tasks is examined to determine if this environment might be more effective with a learning medium using subliminal perception, then was the case of a text editor. This approach is based on the idea that, in contrast to a text editor, with direct manipulation the user would be completely focused on the computer screen where the subliminal message is presented increasing the chances for feedback. The results of this study show no significant difference between subjects who were getting subliminal help screen presentations and those who were getting either subliminal garbage screen presentations or blank screen presentations. This is in conflict with previous research.
