The Short-Time Directed Transfer Function (SDTF) is an estimator based on a multivariate autoregressive model which has proved to be successful in ERP experiments, e.g. those connected with motor action and its imagination.

[Altered visual information processing in anorectic girls--the study on potentials related to the test of attention].

Aim: Combined biological and psychological basis of anorexia nervosa, related to increased self-control, low self-esteem and peculiar motivation, makes a synthetic approach still hard to achieve. The presented study assessed cognitive functions in anorectic patients with respect to both neuropsychological (test of attention) and biological (electrophysiology of information processing) approaches, and their reciprocal interrelations as well.

Methods: Eleven adolescent anorectic females and 10 control subjects performed the Continuous Attention Test CAT.
