Table 1.

Estimated group-level mixing probabilities (α) and mean RTs (μ0) for the fast and slow distributions in context first-selective and context last-selective conditions.

Parameter Context first-selective Context last-selective
Fast Slow Fast Slow
Children
α 0.54 0.46 0.58 0.42
μ0 1202 2375 1707 2410
Adolescents
α 0.74 0.26 0.57 0.43
μ0 788 1490 1199 1813

Note. The α parameters correspond to the probability that a given trial draws its RT from mutually exclusive fast or slow RT distributions, respectively. For context first-selective only, these two distributions can reflect the use of a proactive input gating strategy versus a reactive output gating strategy.
