Publications by Gordon LoganLogan, G. D. (1980). Attention and automaticity in Stroop and priming tasks: Theory and data. Cognitive Psychology, 12, 523-553.Three major variables identified with attention and automaticity in the priming paradigm (i.e., prior associations, current predictive relations, and time difference in the availability of different sources of information) are shown to have parallel effects in the Stroop paradigm. A model is developed to explain the effects in both paradigms in terms of a single decision process that combines evidence from several sources. The model was applied to 2 Stroop experiments, each with 16 undergraduate Ss, in which the faster 2 of 3 stimulus dimensions related associatively and cued through a frequency manipulation the 3rd, which Ss reported. Depending on the direction of the cuing relation, attentional effects enhanced or counteracted automatic effects, and the attentional effects were stronger with the faster unreported dimension than with the slower one. Results corroborate findings in the priming paradigm and confirm the model. |
