\title{Extract bilateral EDA asymmetry features}
\usage{
extract_gazepoint_bilateral_eda_asymmetry(
  dat,
  left_col,
  right_col,
  time_col = NULL,
  group_cols = NULL,
  output_prefix = "beda"
)
}
\arguments{
\item{dat}{A data frame.}

\item{left_col}{Numeric left-side EDA column.}

\item{right_col}{Numeric right-side EDA column.}

\item{time_col}{Optional numeric time column for ordering and gradient
calculation.}

\item{group_cols}{Optional grouping columns.}

\item{output_prefix}{Prefix used for row-level output columns.}
}
\value{
A list with \code{overview}, \code{asymmetry_timeseries}, \code{summary}, and
\code{settings}.
}
\description{
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.
}
\details{
These descriptors quantify bilateral EDA differences only. They do not infer
hemisphere activation, amygdala activity, psychopathology, emotion, stress,
cognition, health status, or diagnosis.
