Mainly, it is critical in childhood managing school-related demands and carrying out daily activities in older ages. This study aims to develop a computerized version of the 4-disc Tower of London (TOL) test. Method: The research was conducted by three studies, including children, adults, and combined samples. The research consisted of children and adults who were 5-53 years. Nonparametric tests were used, thereby that the research data had a non-normally distributed pattern. Research results show significant relationships between age and planning ability, the number of problems solved on the first trial, and the number of problems solved within three trials. Results show that increasing planning ability and the number of problems solved on the first trial was associated with increasing age. The increasing number of problems solved within three trials was associated with decreasing age. There was no significant relationship between age and planning time. Research results show that gender has an effect on planning time in the adult group. Reliability and validity results showed that the computerized version of 4-disc TOL was a reliable and valid measure as the original version. This study was conducted by healthy participants, so there is a need for psychometric study for clinical use in Turkish literature.}, number={3}, publisher={Kastamonu University}
