Spanish normative studies in young adults (NEURONORMA young adults project): norms for the Visual Object and Space Perception Battery and Judgment of Line Orientation tests

The Visual Object and Space Perception Battery (VOSP) and Judgment of Line Orientation tests (JLO) are used in clinical practice to assess visuoperceptual and visuospatial abilities.In this study, as part of the Spanish normative studies project in young adults (NEURONORMA young adults), we present normative data for a short version of the VOSP test and for the JLO test.The sample consisted of 179 participants who are cognitively normal and range in age from 18 to 49 years. Tables are provided to convert raw scores to scaled scores. Education- and sex-adjusted scores were obtained by applying linear regression techniques.Our results show that education and sex only affect scores on the JLO test, and that age has no effect.The normative data obtained will be extremely useful in the clinical evaluation of young Spanish adults.
