The experiment was carried out to determine whether exposure to an uncontrollable relationship between an action and its outcome during a non-aversive pretreatment phase would affect subsequent ratings of perceived control emitted by human participants. Its other aim was to investigate the effect of such pre-exposure on the attentional focus of humans on internal and external cues. Participants were assigned to one of three groups; an uncontrollable pretreatment, a controllable pretreatment, and no pretreatment. Participants exposed to uncontrollable outcomes (unsolvable problems) gave lower ratings of control over a produced outcome than the other two groups, indicating the interference with subsequent judgments of control. The exposure to uncontrollable outcomes also increased levels of distraction produced by an external cue in a reaction time experiment. Such an effect was not found in the groups who had not been exposed to uncontrollable outcomes. These dual effects are similar to those noted in non-humans subjected to uncontrollable outcomes.
