Description The subtest for measuring processing speed is a part of the diagnostic system GIS – Invenio. This system builds on the CHC theory of intelligence. The subtest for measuring processing speed (in the Invenio system the tool is also alternatively called “Oliver and the intergalactic bar”) is a computer-administered method which makes use of the GBA paradigm: in order to increase motivation and lower test anxiety, the tasks are presented as a computer game, including the use of gamified features (graphical elaboration of the game environment, the presence of story characters etc.). In this particular story, the players find themselves in an intergalactic bar, where they help the chef Oliver prepare orders (sundry meals and drinks). The task of the player is to react as quickly as possible to the appearance of the relevant stimulus, i.e. the ingredient which has to be added to the meal. At the same time, the player must ignore the irrelevant stimuli, that is ingredients which don´t belong to the order, or which have already been added. In addition to the reaction time, players also apply their ability of focusing and maintaining attention and inhibition. The subtest comprises several parts, during which the cognitive complexity increases (more difficult orders, more keys necessary to handle the game). This makes it possible to measure potential fluctuations of the processing speed throughout the game. The subtest enables on-line group testing. Evaluation of the results is carried out by means of IRT model, based on the norms acquired during standardization with several hundred children in a number of regions in Czechia. Thanks to the incorporation of the subtest into the Invenio system, the users (parents, teachers, school psychologists) can compare the information on processing speed of the child with the data on his/her other important cognitive abilities.
