Left out and vilified: Do the effects of political metaphors on spatial orientation judgments indicate a taboo effect?

Can aversion from a political ideology lead to rapid, automatic rejection of said ideology? We tested this question in the Israeli political context using a spatial Stroop task to examine whether politically charged left-wing terms would elicit slower verbal latencies. In Study 1 (n = 85), participants were presented with left- and right-wing political terms presented either in a congruent or incongruent spatial location and were asked to verbally indicate only the location of the word. Study 2 (n = 128), replicated this procedure with the Hebrew words for "left" and "right" and examined whether political awareness primes would amplify the effect. Results indicated a slowdown for left-wing related terms above and beyond a congruency effect that was exacerbated under political priming. The slowdown was particularly pronounced among centre-right-wing participants in Study 1, but significant across political orientations in Study 2. Two auxiliary studies rule out the possibility that phonemic features of the words, or spatial preferences could explain these effects. Overall, results support a taboo effect (i.e., implicit aversion) for left-wing political terms.
