Systèmes d'Information et Management


This paper presents two experiments which the aim is to examine the effects of using Information New Technology (INT) on individual's cognitive processing. The first experiment's results show that level expertise didn't affect processing capacities of working memory, neither visuo-spatial imagery abilities (for short-range forecasts). In return, data collected in the second experiment emphasize differences between expert and novice in the way of using INT, specially Internet web site. Indeed, experts implement systematic exploration strategies, which are regulated by semantical information processing.
