The PDT is an adaptive test for testing pitch discrimination.

We also advise mentioning the software versions you used, in particular the versions of the PDT, psychTestR, and psychTestRCAT packages. You can find these version numbers from R by running the following commands:

library(PDT)
library(psychTestR)
library(psychTestRCAT)
if (!require(devtools)) install.packages("devtools")
x <- devtools::session_info()
x$packages[x$packages$package %in% c("PDT", "psychTestR", "psychTestRCAT"), ]

1. If you don't have R installed, install it from here: https://cloud.r-project.org/

2. Open R.

3. Install the ‘devtools’ package with the following command:

install.packages('devtools')

4. Install the PDT:

devtools::install_github('sebsilas/PDT')

You can demo the PDT at the R console, as follows:

# Load the PDT package
library(PDT)

# Run a demo
PDT_standalone(demo = TRUE)

# Include in timeline
