^†Control results were not available.

^††Results reported in Freedman and Martin (2001).

^†††Highest list length tested on the controls, results reported in Martin, Lesch, and Bartha (1999).

^▲Abnormally large interference effects on accuracy (p against controls < .05).

^**Abnormally large interference effects on both untransformed and log-transformed RTs (both ps against controls < .05).
