How the brain works during reading
Arthur Jacobs
Freie Universität Berlin, Arbeitsbereich Allgemeine und Neurokognitive Psychologie, Berlin, Deutschland
Mankind exists for 2-3 million years, but only about 6 thousand years ago men started
to write and read, leaving little time for the human brain to develop neuronal structures
specialized for processing script. Using modern neuroimaging techniques, however, reading-specific
activities can be detected in all four lobes of the brain and the cerebellum.
Starting about 1/10 of a second after our gaze has fixated a word during reading, the occipital
lobes already have developed a sort of typeface representation. Another 1/10 of a
second later, this „orthographic code“ is coupled with corresponding phonological codes
in the left temporal lobe. After about ¼ of a second semantic associations are computed
involving the left frontal lobe and the so-called lexical access provides conscious information
about all kinds of word properties. Using computer models one can analyze and
simulate this magical moment of lexical access, the basic process underlying the reading
skill. The factors that influence its speed and quality will be discussed in this talk in the
light of new methods and models used in the study of reading and reading disorders.

Diagnostik der Dyskalkulie in der Praxis mit dem RZD 2-6
Claus Jacobs
Psychologische Kinderambulanz der Universität Bremen, Bremen, Deutschland
Von Rechenstörungen sind ca. 6% der Kinder betroffen, also etwa ebensoviel wie von
der Lese/Rechtschreibstörung. In den letzten Jahren haben sich die Forschungsbemühungen
zur Zahlenverarbeitung und Rechenfertigkeiten deutlich vervielfacht.
In der Praxis setzt die Diagnostik und Therapie von Rechenstörungen umfassende
