calculateCAF: calculateCAF

In DMCfun: Diffusion Model of Conflict (DMC) in Reaction Time Tasks

Description

Calculate conditional accuracy function (CAF). The DataFrame should contain columns defining the participant, compatibility condition, RT and error (Default column names: "Subject", "Comp", "RT", "Error"). The "Comp" column should define compatibility condition (Default: c("comp", "incomp")) and the "Error" column should define if the trial was an error or not (Default: c(0, 1) ).

Usage

calculateCAF(
  dat,
  nCAF = 5,
  columns = c("Subject", "Comp", "RT", "Error"),
  compCoding = c("comp", "incomp"),
  errorCoding = c(0, 1)
)

Arguments

dat	DataFrame with columns containing the participant number, condition compatibility, RT data (in ms) and an Error column.
nCAF	Number of CAF bins.
columns	Name of required columns Default: c("Subject", "Comp", "RT", "Error")
compCoding	Coding for compatibility Default: c("comp", "incomp")
errorCoding	Coding for errors Default: c(0, 1))

Value

calculateCAF returns a DataFrame with conditional accuracy function (CAF) data (Bin, comp, incomp, effect)

Examples

# Example 1
dat <- createDF(nSubjects = 1, nTrl = 10000, design = list("Comp" = c("comp", "incomp")))
dat <- addDataDF(dat,
                 RT = list("Comp_comp"   = c(500, 80, 100),
                           "Comp_incomp" = c(600, 80, 140)),
                 Error = list("Comp_comp"   = c( 5, 4, 3, 2, 1),
                              "Comp_incomp" = c(20, 8, 6, 4, 2)))
caf <- calculateCAF(dat)

# Example 2
dat <- createDF(nSubjects = 1, nTrl = 10000, design = list("Congruency" = c("cong", "incong")))
dat <- addDataDF(dat,
                 RT = list("Congruency_cong"   = c(500, 80, 100),
                           "Congruency_incong" = c(600, 80, 140)),
                 Error = list("Congruency_cong"   = c( 5, 4, 3, 2, 1),
                              "Congruency_incong" = c(20, 8, 6, 4, 2)))
head(dat)
caf <- calculateCAF(dat, columns = c("Subject", "Congruency", "RT", "Error"),
                    compCoding = c("cong", "incong"))
