A dataset containing the response recorded from a tactile discrimination task (nine participants). In a forced-choice experiment, participants were required to discriminate the motion speed of a moving surface by touching it. Simultaneously with the motion stimulus, a 32Hz masking vibration occurred in half of the trials.
data(vibro_exp3)A data frame with 126 rows (14 observations x 9 participants) and 5 variables:
numeric, speed of the moving surface (in cm/s, range c(1,16))
factor representing the vibration frequency of the masking stimulus. Two levels: 32 (vibration in the experimental condition, in Hz) or 0 (no vibration - control condition)
proportion of trials in which the comparison stimulus was judged as faster than the reference
proportion of trials in which the comparison stimulus was judged as slower than the reference
participant's identification code
