Data from tactile discrimination task - (Dallmann et al., 2015).
Description
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.
Usage
data(vibro_exp3)
Format
A data frame with 126 rows (14 observations x 9 participants) and 5 variables:
- speed
numeric, speed of the moving surface (in cm/s, range
c(1,16))- vibration
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)
- faster
proportion of trials in which the comparison stimulus was judged as faster than the reference
- slower
proportion of trials in which the comparison stimulus was judged as slower than the reference
- subject
participant's identification code
Source
Original data were published in Dallmann et al. (2015).
