Describing Behavioral Variability

Variability Management on Behavioral Models

This paper deals with managing variability on behavioral models. Such models are generally more complex, less tractable by hand than the static, structural parts of a system description. This calls for specific support to check the consistency of variability expression model-wide: defining some elements as variable may impact several behavioral constructs, even elements that designers may not b...

Increased Brain Signal Variability Accompanies Lower Behavioral Variability in Development

As the brain matures, its responses become optimized. Behavioral measures show this through improved accuracy and decreased trial-to-trial variability. The question remains whether the supporting brain dynamics show a similar decrease in variability. We examined the relation between variability in single trial evoked electrical activity of the brain (measured with EEG) and performance of a face...

A canonical neural mechanism for behavioral variability

The ability to generate variable movements is essential for learning and adjusting complex behaviours. This variability has been linked to the temporal irregularity of neuronal activity in the central nervous system. However, how neuronal irregularity actually translates into behavioural variability is unclear. Here we combine modelling, electrophysiological and behavioural studies to address t...

Intraindividual Variability 1 Running head: INTRAINDIVIDUAL VARIABILITY Describing Intraindividual Variability at Multiple Time Scales Using Derivative Estimates

The study of intraindividual variability is central to the study of individuals in psychology. Previous research has related the variance observed in repeated measurements (time series) of individuals to trait–like measures that are logically related. The use of intraindividual measures such as intraindividual standard deviation or the coefficient of variation are likely to be incomplete repres...
