This is an OSF site for Meier (2021), "Testing the Attention-distractibility Trait" Here you can find: (a) Preregistration (also available at: https://aspredicted.org/ng4ar.pdf) (b) 8 datafiles from which I conducted analyses. 6 files provide the trial-level data from the tasks. ospan.txt from the operation complex span task. sspan.txt from the symmetry complex span task. AL.txt from the antisaccade task. SART.txt from the SART task. QA1.txt which contains infrequency and IPI-daydreaming items, and the QB.txt which contains ADHD items. These files are the output form the eprime tasks. The .RMD file makes use of these text files (these files will need to be in the home directory for the .RMD file to run). The .RMD file processes these data files, assigns better variable names and then conducts descriptive and inferential statistics. The other file "AD aggregated data.csv" contains the aggregated (by subject) data for all measures. (c) An R mardkown file (.RMD) with analysis code for all analyses (d) a HTML version of the .RMD file. This file can be viewed in any standard web browser. All analysis code and results from that code (and some limited annotation) are visible. (e) A variable key for the aggregated data file ("varkey_aggregated data.csv"). (f) eprime versions of the SART (SARTcorrected.es2) and antisaccade (anti-letters.es2) task used. (g) An experimental session protocol
