| Abstract: | The present study investigated whether it is likely that stimulus-response translation contributes significantly to sequence execution in the discrete sequence production (DSP) task after extensive practice. This was done by inhibiting two other processing strategies, namely, the use of motor chunks and central-symbolic representations. In a DSP study, 24 participants counted tones and used an unpracticed hand configuration for sequence execution after extensive practice. Based on the assumption that each manipulation slowed responses by inhibiting a processing strategy, we expected the combined slowing of tone counting and using an unpracticed hand configuration to be larger than the added slowing of each manipulation alone. However, the results showed an additive increase of mean reaction times (RTs) when combining the two manipulations. To determine whether this can be explained by significant contribution of stimulus-response translation, we used the data of the DSP study to compare a model including stimulus-response translation with a model excluding it. The simulation of both models showed that stimulus-response translation likely contributed to sequence execution, but that it cannot explain the additive increase of RTs either. This could mean that more processing strategies were used or that other factors such as biomechanical differences affected mean RTs. |
