Co sie kryje w nieistotnych efektach statystycznych? Możliwości zastosowania analizy supresji w psychologii społecznej

This article discusses the topic of suppression effects that have often been reported in recent social psycho¬logical literature. Suppression takes place when a mediating variable enhances predictive power of inde¬pendent variable on dependent variable. In this way we are able to capture with statistical analyses all sorts of theories of opponent processes that appear not only in motivation psychology but also in other areas of social psychology. Using latest social/personality psychology research examples, we describe three types of suppression effects (classical, net and cooperative) with possibilities of their use in research. At the end of the article we propose an example of suppression analysis conducted on a fictional dataset.
