brain {npmc}R Documentation

reaction time of brain-damaged patients

Description

The brain data frame has 90 rows and 2 columns. It contains pairs of observations (var) and factor levels (class).

Usage

data(brain)

Format

This data frame contains the following columns:

class
- factor with levels c = control-group, l = left hemisphere brain-damage, r = right hemisphere brain-damage
var
- score for the reaction

Details

The effects of uniliteral left hemisphere (LH) and right hemisphere (RH) lesions on the accuracy of choice and speed of response in a four-choice reaction time task were examined by Tartaglione et al. (1191). The subjects consisted of 30 controls, 30 LH and 30 RH brain-damaged patients, so this is an example for a balanced one-factorial design.
