The Human Problem-Solving Space Detection Test (HPSSDT), a unique assessment tool intended to measure people's capacity to recognize and traverse problem-solving settings, is examined in this study for validity and reliability. The purpose of the HPSSDT is to assess cognitive processes associated with spatial reasoning, problem-solving techniques, and decision-making procedures. The exam was given to a broad sample of people, and both traditional test theory and contemporary psychometric techniques were used to assess the data. Strong test-retest reliability (r = 0.85) and internal consistency (Cronbach's alpha = 0.89) are shown by the results. Factor analysis provided evidence for construct validity by identifying different aspects of problem-solving skills. By comparing HPSSDT scores with recognized assessments of cognitive function and problem-solving ability, criterion validity was established. The study finds that the HPSSDT is a viable and dependable instrument.
