EXAMINER FAQ

General

Q: Are there norms for each individual subtest or just the composite scores? We are hoping to get age- or age-and-education-based norms.
A: We don’t provide norms, but we’re happy to give you our dataset that includes around 600 controls across the age spectrum. Please email us for the dataset.

Q: Where do I get the latest manual and forms?
A: Here. The links are

Installation

Q: I am signed in with administrator privileges on my Windows 7 machine, but I still cannot install the upgrades. What am I missing?
A: In Windows 7 simply being logged in as administrator is not enough, you need to run the program as an administrator while performing the upgrade. To do this, right-click the PschoPy icon and select Run as administrator, then perform the upgrade.

Running Tasks

Q: The program either freezes or I get errors. What’s wrong?
A: Make sure you are using the correct version of PschoPy, 1.73.05. The easiest way to do this is to install from the CD in two steps: Install version 1.73.02 using the provided installer file; and then, use the built-in updater to update to version 1.73.05 using the provided file. Both files are provided on the CD in the same folder. DO NOT use the auto-update feature.

Q: I’m still getting errors. What should I do?
A: Send the tech support team your environment output file so they can better troubleshoot. The file should be located in the data folder in the folder where you installed EXAMINER, which should be: [Desktop]\Examiner3_2\data. The filename should start with the word ‟Environment_”. Also, send a description of the error or the precise text of the error message.

Q: Should I upgrade any of the software to newer versions?
A: No. You should not upgrade PsychoPy or the R software.

Q: Does it matter whether my operating system ins 32-bit or 64-bit?
A: No, it does not matter.

Q: Why is the error score blank?
A: The error score must be manually computed before passing the data to the R scoring program. Refer to the manual for computation directions.

Q: What are the Likert scale values on the Behavior Rating Scale?
A: 0=None; 1=Mild; 2=Moderate; 3=Severe. The total is a sum of the items.

Q: Is the composite score a whole number?
A: The composite scores and standard errors are decimals with positive and/or negative values.

Q: Is the Continuous Performance Task the Conners’ CPT-II version?
A: No, it is a custom task designed specifically for this battery based on pilot testing.

Scoring and Using the R Scoring Program

Q: When I try to run the command to score the file, I get a response that says “Scoring row 1 of 150,” then it seems to stop, and says “Error in library(ltm): there is no package called ‘ltm’
A: You need to install the ltm package. Refer to the section in the manual on installing R.

Q: How do I prepare an input file to run in R?
A: The R scoring program requires an input file in .CSV (comma-separated-values) format with 11 “donor” variables and a variable indicating the language of the battery administration (this requires a value of ‘1’ or ‘2’, NOT ‘ENGLISH’ or ‘SPANISH’). Any ‘-5’ values in the input file should be removed before running in R. Please refer to pages 77–78 in the NIH EXAMINER User Manual for guidance on preparing the input file. There is also an example input file in the test subdirectory of the scoring program called ExampleScoringInput.csv.

Q: Some people obtained negative values for flanker_error_diff and/or shift_error_diff. Do I include these values when calculating the error_score variable?
A: Any negative values for flanker_error_diff or shift_error_diff should be converted to ‟0” before including them in the error score calculation.
