Bilingualism, Self-Control, and Impulsivity do not Predict Flanker, Simon, or Stroop-Like Interference: Gender Does

More than 130 university students (60% bilinguals) completed four computer-controlled tasks reputed to measure different types of inhibitory control (flanker, Simon, spatial-Stroop, vertical Stroop), the self-control scale developed by Tangney, Baumeister, & Boone (2004), and three of the UPPS impulsive-behavior subscales (premeditation, urgency, perseverance) developed by Whiteside et al. (2001). As usual there is little convergent validity between the measures of inhibitory control derived from the computerized tasks and the pattern is only somewhat consistent with standard taxonomies regarding S-S versus S-R compatibility. Neither bilingualism, nor self-control, nor impulsivity predicted the interference scores in the computerized tasks. In contrast gender, frequency of playing video games, ability in team sports, and frequency of working-out did predict the interference scores. Men were much faster on incongruent trials, but only slightly faster on congruent trials. Other failed predictors include music training, music performance, SES, mindfulness, meditation, immigrant status, and attitude toward distraction. The Simon and spatial-Stroop tasks were identical to those used by Blumenfeld and Marian (2014) and the absence of any main effects or interactions involving bilingualism constitute a failure to replicate the bilingual advantages in stimulus-stimulus inhibition they reported. The overall results are consistent with the conclusion that these nonverbal interference tasks do not provide valid measures of general inhibitory control and furthermore do not associate with commonly used measures of self control or impulsivity. The results and conclusion call into question the degree to which the male advantage in interference scores should be generalized to executive functioning outside the laboratory.
