Description Attention bias Pupillometry Vignettes
itrak
provides functions to facilitate the processing of data from
visual attention experiments. The functions can be divided into two main
categories: attention bias and pupillometry. In addition, more generic
functions are provided to address common data-cleaning chores associated
with multi-trial experimental data.
The attention bias functions calculate attention bias scores using data from
tasks such as the dot probe. The main function, summarize_bias
,
provides a summary table with metrics of mean bias and trial-level bias.
The pupillometry functions denoise and standardize data from the
continuous measurement of pupil diameter. get_artifacts
and
fix_artifacts
identify and remove artifacts, such as those
caused by blinking, and a low_pass_filter
is provided to remove
other sources of high-frequency noise. normalize
standardizes
pupil measurements into units of relative change from baseline.
