College undergraduates were given Zelniker and Jeffrey's modification of the Matching Familiar Figures Test to assess its psychometric credibility and construct validity for adult problem solvers. The modified test has improved internal consistency and stability over the original. The construct's possible correlation with general problem solving…

The components underlying a variety of self-report measures of impulsivity were investigated, as well as the components underlying four behavioral measures involving reaction time, time estimation, and time production. Three broad factors were identified: carefree, spontaneous, and not persistent. Implications for measurement were discussed.…

The internal consistency reliability and discriminant validity of the adult version of the Matching Familiar Figures Test (MFF) were determined for a sample spanning adulthood; age and sex differences were also investigated. Sixty-three men and 63 women ranging from 18 to 78 years of age, with at least 12 years of schooling, were administered…
