The autocorrelation function of pattern fluctuation is used to study
soft-mode turbulence (SMT), a spatiotemporal chaos observed in homeotropic
nematics. We show that relaxation near the electroconvection threshold deviates
from the exponential. To describe this relaxation, we propose a compressed
exponential appearing in dynamics of glass forming liquids. Our findings
suggest that coherent motion contributes to SMT dynamics. We also confirmed
that characteristic time is inversely proportional to electroconvection's
control parameter.
