Introduction:
The Salthouse Perceptual Comparison Test (SPCT) assesses the processing and perceptual speed. Although this test is widely used in neuropsychology, it has not normative data adapted to Spanish population.
Aim:
To normalize and standardize the SPCT in Spanish population taking into account the sociodemographic characteristics of our society.
Subjects And Methods:
This study is part of the multisite Normacog project. Seven hundred participants from 18 to 90 years old were assessed using the SPCT. The effect of sociodemographic characteristics such as age, level of education and sex, were analyzed on the SPCT performance, and percentiles and scalar scores adjusted by age and level of education were created.
Results:
The effect of age and level of education on the SPCT variables analyzed (correct answers and errors of the SPCT-3 and SPCT-6) was statistically significant. Age explained the higher percentage of the variance in SPCT (SPCT-3: 47%; SPCT-6: 45%). The older participants with lower level of formal education obtained worse performance in the number of correct answers and higher number of errors.
Conclusion:
The present study reports the first normative data of the SPCT for Spanish population taking into account the sociodemographic characteristics of Spain which confirm the influence of age and level of education on the performance of the SPCT. As part of the Normacog project, this study presents the administration and correction instructions.

Testing a Claim about Standard Deviation
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...
