Extract bilateral EDA asymmetry features

Computes left-right electrodermal activity asymmetry descriptors from two simultaneously recorded EDA channels. The function returns row-level asymmetry time series and group-level summaries.

Usage

extract_gazepoint_bilateral_eda_asymmetry(
  dat,
  left_col,
  right_col,
  time_col = NULL,
  group_cols = NULL,
  output_prefix = "beda"
)

Arguments

dat

A data frame.

left_col

Numeric left-side EDA column.

right_col

Numeric right-side EDA column.

time_col

Optional numeric time column for ordering and gradient calculation.

group_cols

Optional grouping columns.

output_prefix

Prefix used for row-level output columns.

Value

A list with overview, asymmetry_timeseries, summary, and settings.

Details

These descriptors quantify bilateral EDA differences only. They do not infer hemisphere activation, amygdala activity, psychopathology, emotion, stress, cognition, health status, or diagnosis.
