The aim of the study was to investigate the relationship between Pavlovian traits of temperament - strength of excitation, strength of inhibition and mobility of nervous processes - and measures of fluid and crystallized intelligence depending on the age of subjects. The psychometric instruments were administrated to seven age groups - the youngest group consisted of kindergarten children and the oldest one of subjects aged 60-80 years. There were 831 participants overall. Some hypothetical relationships were considered, especially with respect to age differences. The analyses allowed concluding that there is a modest but significant relationship between the mobility of nervous processes and intelligence - this refers to fluid as well as to crystallized intelligence. The relationship was the most powerful in adults, and the weakest - in children. The data confirmed that the structure of these relationships differ between age groups. Additionally the relationships between temperament, intelligence and education were examined.
