This behavioral study shows for the first time that the auditory perception of vowels influences silent labial responses. During a perceptual decision task, participants were instructed to choose and execute a silent labial response (lip protrusion versus chin lowering) as quickly as possible depending on the vowel they had perceived auditorily. The main result showed that gestural compatibility between the silent labial response and the articulation of the perceived vowel led to better performance (in terms of response times and errors) than an incompatibility between them. By including a somatic compatibility effect in a more dynamic gestural compatibility effect, this new result suggests that the role of motor activity during speech auditory perception lies in mentally simulating an articulation of the perceived phoneme.

There are a few works undertaken to verify the accuracy of corrosion measurements. In general, it is assumed that potentiostats are correctly fabricated and then efforts are made to check the repeatability of certain measurement types as polarization curves, with the same or different operator or to calibrate corrosion rate measurements with gravimetry. This paper makes a more in-depth study about repeatability and reproducibility of the measurements and deals with the comparison of corrosion parameters measured in concrete with various degradation types such as carbonation or chloride attack. Different field and laboratory devices were compared.
