Abstract

The present study describes the normative data and convergent validity of the Poreh Spatial Memory Test (PSMT). 204 participants (96 males and 108 females) between the age of 18 to 85 years were administered the PSMT. A subsample was administered the Rey Osterith Complex Figure Test (ROCFT) as well as the Rey Auditory Verbal Learning Test (RAVLT) and another subsample was administered the Biber Figure Learning Test – Extended (BFLT-E). The present study demonstrated that the mean scores for the learning trials within each group exhibited robust inverse logarithmic learning curves. Accordingly, three indices were derived: learning, learning curve, and delayed retention. As one might expect from a “pure” visuospatial memory test, age, but not gender or education, correlated with the PSMT learning and delayed retention scores. Additional analysis revealed that the PSMT correlated significantly with the ROCFT and the BFLT-E, supporting the convergent validity of the new measure. Age based norms for this new measure were computed for the learning and delayed retention subscores, using a regression based procedure. Additional studies using various clinical samples including patients with lateralized brain injuries are underway to further establish the sensitivity and specificity of the PSMT.
