    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Brain mechanisms; Brownian motion; drift; dynamical systems; fractal; human; Gaussian noise; Hurst exponent; time; time series analysis; timing; Psykologi; Psychology; Psykologi; fysiologi; Physiology;

    Sammanfattning : Behaviour occurs in time, and precise timing in the range of seconds and fractions of seconds is for most living organisms necessary for successful interaction with the environment. Our ability to time discrete actions and to predict events on the basis of prior events indicates the existence of an internal timing mechanism. LÄS MER
