abstract = {While there is a clear link between impairments of
executive functions (EFs), i.e. cognitive control mechanisms
that facilitate goal-directed behavior, and speech problems,
it is so far unclear exactly which of the complex subdomains
of EFs most strongly contribute to speech performance, as
measured by verbal fluency (VF) tasks. Furthermore, the
impact of intra-individual variability is largely unknown.
This study on healthy participants (n = 235) shows that
the use of a relevance vector machine approach allows for
the prediction of VF performance from EF scores. Based on a
comprehensive set of EF scores, results identified cognitive
flexibility and inhibition as well as processing speed as
strongest predictors for VF performance, but also
highlighted a modulatory influence of fluctuating hormone
levels. These findings demonstrate that speech production
performance is strongly linked to specific EF subdomains,
but they also suggest that inter-individual differences
should be taken into account.},
