Razvoj in preverjanje veljavnosti računalniške naloge za merjenje sposobnosti načrtovanja : magistrsko delo

Mikolič, Petra (author), Podlesek, Anja (mentor)

Resna računalniška igra CCRacer 2.0 vključuje naloge za merjenje različnih izvršilnih funkcij. V magistrskem delu smo razvili novo nalogo za merjenje načrtovanja, procesa, s katerim identificiramo in organiziramo korake za dosego cilja. Nalogo sestavljajo problemi, pri katerih mora udeleženec označevati pot avtomobilu tako, da na cesti pobira in odlaga pakete po določenih pravilih, pri tem pa skuša narediti najkrajšo pot. Namen magistrske raziskave je bilo preverjanje veljavnosti naloge in zanesljivosti testnega dosežka. V testiranju na daljavo je sodelovalo 97 udeležencev, ki so poleg testa CCRacer – načrtovanje reševali še štiri kognitivne teste. Dva testa načrtovanja (Londonski stolp in Problem trgovskega potnika) sta bila namenjena preverjanju konvergentne veljavnosti, test vidnoprostorskega delovnega spomina (Corsi kocke) in test hitrosti procesiranja informacij (Zamenjava znakov) pa preverjanju diskriminantne veljavnosti testa CCRacer – načrtovanje. Pri reševanju testov smo zbirali podatke o hitrosti in uspešnosti reševanja. Poleg izvedbe testov so udeleženci izpolnili vprašalnik z demografskimi podatki, ocenjevalnimi lestvicami o zanimivosti posameznih testov načrtovanja in motiviranosti pri njihovem reševanju in vprašanji o načinu reševanja nalog ter impulzivnem vedenju. Retestno zanesljivost nove naloge smo preverili s ponovnim merjenjem, na katerem je sodelovalo 39 udeležencev s prvega testiranja. Zmerno visoke korelacije med testi načrtovanja in nizke korelacije s testoma drugih kognitivnih funkcij so nakazale, da nova naloga v okolju CCRacer meri sposobnost načrtovanja. Raziskava je podala obetavne rezultate za uporabo nove naloge, ki bi z nekaj spremembami in testiranjem na različnih starostnih skupinah lahko postala primeren pripomoček za merjenje načrtovanja. Udeleženci so novo nalogo ocenili kot zanimivejšo in bolj motivirajočo od klasičnih testov načrtovanja, kar je spodbudno za prihodnji razvoj naloge v namene kognitivnega treninga.

• Title: Development and Validation of Computerized Task for Measuring Planning Ability

Abstract

The serious computer game CCRacer 2.0 includes tasks to measure different executive functions. In the master thesis, we developed a new task to measure planning, a process used to identify and organise the steps to achieve a goal. The task consists of problems in which a participant has to mark the path of a car by picking up and dropping off packages on the road according to certain rules, while trying to take the shortest route. The aim of the master's research was to check the validity of the task and the reliability of the test score. A total of 97 participants took part in the remote testing and, in addition to the CCRacer – planning test, four cognitive tests were administered. Two of the planning tests (Tower of London and the Traveling salesman problem) were used to test convergent validity, while the visuospatial working memory test (Corsi block-tapping test) and the processing speed test (Letter-digit span) were used to test the discriminant validity of the CCRacer – planning test. Speed and performance data was collected when solving the tests. In addition to tests, participants completed a questionnaire with demographic data, self-report scales on the interestingness of each planning test and the motivation to solve them, questions on how they solved the tasks and on impulsive behaviour. The test-retest reliability of the new task was assessed by performing a second measurement, attended by 39 participants from the first testing. Moderately high correlations between the planning tests and low correlations with tests of other cognitive functions indicated that the new task in the CCRacer setting measures planning ability. The study provided encouraging results for the use of the new task, which, with some modifications and testing on different age groups, could become a suitable tool for measuring planning ability. Participants rated the new task as more interesting and motivating than traditional planning tests, which is promising for future development of the task for cognitive training purposes.
