Figure 8. (Corrected) lexical decision latencies for auditory probes presented during picture naming. The y-axis shows the lexical decision latency for a probe during picture naming minus the decision latency for the same auditory probe without concurrent picture naming. Probes could be identical to the target name (e.g., "sheep" for target sheep), semantically related to it ("goat"), phonologically related to the semantic alternative ("goal"), or wholly unrelated to target or semantic alternative ("house"). Data show that a semantically active semantic alternative is phonologically inert. Data from Levelt et al. (1991a).
