TL;DR: Results from 3 further experiments support 4 main conclusions: a processing bottleneck exists even after extensive practice, the principal cause of the reduction in PRP interference with practice is shortening of Task 1 bottleneck stages, and the extent of PRP reduction with practice depends on the modalities of the 2 responses.

TL;DR: It is shown that a bottleneck need not produce any observable interference, provided that there is no temporal overlap in the demand for bottleneck stages on the 2 tasks, and that a "latent" bottleneck is especially likely after practice, when central stages are short.

TL;DR: Response disengagement affords some protection against alcohol-induced impairment of inhibition, indicating that not all aspects of motor processing requiring inhibition are equally impaired by alcohol.

TL;DR: The evidence supports a resource limitation account that argues that alcohol reduces capacity to process information required for execution and suppression of responses on tasks requiring response execution and response suppression.
