This paper describes the structure and contents of EC301, a standardiz
ed testing battery for the evaluation of brain-damaged adults in the a
rea of calculation and number processing. The battery was administered
to 180 normal subjectsstratified by education(3 levels), age (3) and
gender. EC301 is composed of alarge variety of tasks dealing with basi
c arithmetic skills, and their linguistic, spatial, and mnesic dimensi
ons. The three main notational systems for numbers - Arabic digits, wr
itten verbal, and spoken verbal number forms - are explored. Analysis
of error rates indicated the effect of some demographic factors (princ
ipally, education; incidentally, gender) on normal performance in some
tasks.
