By combining the two-to-one Stroop paradigm (De Houwer, 2003) with the single-letter coloring and cueing (SLCC) procedure (Besner et al. 1997), this research addressed current controversies relative to the contribution of semantic conflict to the (overall) Stroop interference effect and to its reduction by SLCC. The data, collected in a considerable sample and analyzed with both inferential and Bayesian approaches, appear most consistent with Manwell et al.’s Account 1 suggesting that SLCC affects the magnitude of both standard and semantic Stroop interference. The most clear-cut result reported in the present study is the unambiguous presence of semantic conflict in the Stroop task. This leaves no doubt – in complete contrast to dominant single-stage response competition models (e.g., Roelofs, 2003) – that selection occurs at the semantic level in the Stroop task. The immediate implications for the composite (as opposed to unitary) nature of the Stroop interference effect and other still unresolved issues in the Stroop literature are outlined further. |
