Transformation of Thought Suppression Functions Via Same and Opposite Relations

The aim of this study was to investigate transformation of thought suppression functions via ‘same’ and ‘opposite’ relations. In Experiment 1 participants were given training and testing with the aim of generating same and opposite relational responding in two five-member relational networks. They then had to suppress a target word from one of the two networks, while words appeared individually onscreen including the target, and words either in the same (target) or a different (nontarget) network. They could remove any word by pressing the spacebar. Findings showed more frequent and faster removal of the target than other words and of words in the target network than other words. Experiment 2, the aim of which was to include predominantly ‘opposite’ relations in the relational networks, produced a similar but weaker pattern. Experiment 3 replicated the pattern seen in Experiment 2, while showing that the relations designated as opposite produced a more conventional transformation of functions in a context other than thought suppression.
