Subchance perception: Anxious, non-defensive individuals identify subliminally-presented positive words at below-chance levels

People who chronically experience anxiety are biased towards subliminally-presented negative information. Recent research has shown that they may also avoid subliminally-presented positive information. However, these findings are equivocal due to the limitations of previous paradigms and measures. This paper reports two experiments demonstrating that highly anxious, non-defensive individuals exhibit subchance perception when attempting to identify subliminally-presented positive words; that is, they identify such words with accuracy rates that are below chance (guessing). Participants attempted to identify masked positively and negatively valenced words that had been presented briefly (6.4 ms) in a two-alternative forced-choice paradigm. In Experiment 1, persons high in trait anxiety and low in defensiveness identified positive words at below-chance levels and negative words at above-chance levels. No other participant-group’s performance differed from chance. In Experiment 2, persons high in trait anxiety and low in defensiveness again exhibited subchance perception of positive words when responding quickly. This represents the clearest evidence to date that anxious, non-defensive individuals systematically avoid subliminally-presented positive information.
