New methodological advice for research in subliminal psychodynamic activation.

Recent integration among approaches to perception without awareness has brought the usefulness of Subliminal Psychodynamic Activation into renewed focus. Several authors have discussed the possible detrimental impact on interpretation when control phrases are used that for some participants may be less than affectively neutral (e.g., Fudin, 1986; Greenberg, 1997). In this continuing commentary, we argue that the neutrality of a substantive stimulus is an insoluble issue, and instead the suitability of controls for a given study should be emphasized. Also, we discuss the apparent confusion between experimental psychodynamics and efforts to answer Greenwald's 1992 "two-word challenge."
