plotItemVar {IAT}

Plot IAT item variability

Description

Plot mean item reaction time with 95% confidence intervals to see how reaction time varies by item. The data is automatically cleaned (i.e., no error trials, and trials with RT > 10000 or < 180 are deleted) to avoid over/underinflation of mean estimates and only includes trials from essential blocks.

Usage

plotItemVar(my_data, block_name, trial_blocks, item_name, trial_latency,
  trial_error)

Arguments

my_data

The raw dataframe to be used

block_name

A string of the variable name for the blocks

trial_blocks

A vector of the four essential blocks in the seven-block IAT (i.e., B3, B4, B6, and B7).

item_name

A string of the variable identifying the items

trial_latency

A string of the variable name for the latency of each trial.

trial_error

A string of the variable name identifying whether a trial was an error or not (1 = error)
