Description

Simulate Response Data Files From Longitudinal Illusory Truth Study

Usage

simulate_resp_files(
  nsubj,
  phase_eff = c(0, 0, 0, 0),
  path,
  overwrite = FALSE,
  p_too_fast = 0.01,
  p_too_slow = 0.01,
  p_incomplete = 0.01,
  p_cheat = 0.01,
  p_no_consent_all = 0.01,
  p_no_consent_phase = 0.01,
  p_nonnative = 0.01,
  p_repeater = 0.01,
  duration_range_1 = c(180, 2400),
  duration_range_all = c(60, 1800)
)

Arguments

nsubj	Number of subjects; must be a multiple of 8.
phase_eff	A four-element vector giving the size of the illusory truth effect at each of the four phases (on the log odds scale). Use rep(0, 4) for testing Type I error rate. A value of .14 gives an effect of approximately 1/10 of a scale point.
path	Path to subdirectory where resulting files will be stored; will be created if it does not exist.
overwrite	Whether to overwrite the subdirectory if it exists.
p_too_fast	Probability that the respondent completed the task faster than the cutoff time ('Duration (in seconds)' less than duration_range_1[1] for Phase 1, less than duration_range_all[1] for all other phases).
p_too_slow	Probability that the respondent completed the task slower than the cutoff time ('Duration (in seconds)' greater than duration_range_1[2] for Phase 1, greater than duration_range_all[2] for all other phases).
p_incomplete	Probability that the respondent failed to complete the task ('Finished' = FALSE).
p_cheat	Probability that the respondent looked up answers ('cheat' = "Yes...")
p_no_consent_all	Probability the respondent refused consent to the full study.
p_no_consent_phase	Probability the respondent refused consent to a phase of the study.
p_nonnative	Probability the respondent is not a native English speaker.
p_repeater	Probability that the respondent just pressed the same key over and over for at least one phase.
duration_range_1	Two-element vector giving the range of acceptable task durations for Phase 1.
duration_range_all	Two-element vector giving the range of acceptable task durations for Phases 2, 3, and 4.

Details

Simulates response data and writes a set of CSV files out to path in Qualtrics format. The file names are of the format PXLY.csv, where X is the phase number (1-4) and Y is the list number (1-8). So P2L6.csv is the file for phase 2 of list 6. When we ran a pilot study, we discovered that the data files had a somewhat different structure from this, but we nevertheless opted to retain this function rather than rewriting it to match the new format.

Value

A character vector with the names of the data files.

Examples

td <- tempdir()
simulate_resp_files(40, path = td, overwrite = TRUE)
dir(td) # show the response files
unlink(td, TRUE, TRUE) # cleanup
