The present application is a continuation of the 4-year OZR project of Inge Zeeuws and has for goal to allow for the doctoral theses to be completed. This project has known a delay due to the use of a specific research design. After all, in most of the experiments a within-subjects design was used, which means that all participatns took part in two sessions, one with d-amphetamine and one with placebo. The diminution of convincing conclusions, two questions remain unanswered. These answers would allow the researcher not only to succesfully round up her doctorate, but also to publish research papers in international journals with peer-review, which would positively contribute to a valorization of the results that flow from the research.
With this project we want to investigate some important characteristics of human memory consolidation. Consoidation means that newly acquired information is steadily anchored in memory. It refers to the fact that long-term memory storage is a gradual process that proceeds for some time after learning (Mc Gauch, 2000). Following previous research in our laboratory we investigated the consolidation process via the administration of d-amphetamine (Soetens et al, 1995; Soetens et al, 1993). The ultimate question to answer in this project is whether implicit and explixit learning have the same consolidation characteristics.
