- Abstract
Previous research revealed associations between an individual's occupation and cognitive abilities. However, the underlying causal relation is not always clear and only few studies focused on a critical component of executive functioning, namely working memory updating (WMU). Study 1 examined whether restaurant ticket collectors (N = 53) have a better WMU ability compared to a group of security guards (N = 49) that was matched on relevant variables. Study 2 examined transfer effects of a computerized working memory training program in students. The program simulated elements of a restaurant ticket collector's daily work requirements. In Study 1, the ticket collectors performed better than the guards on WMU tasks. In Study 2, using an active control group (N = 33) as comparison, the trained students (N = 33) displayed beneficial training effects on transfer WMU tasks but not on general intelligence tasks. The results support the general notion of repeated experience with occupation-specific demands affecting specific objectively-assessed cognitive abilities.
