vibro_exp3: Data from tactile discrimination task - EXP3

Description Usage Format Source References

Description

A dataset containing the response and stimuli 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

1

Format

A data frame with 72 rows and 6 variables:

speed

a numeric vector giving the motion speed in cm/s of the moving surface

vibration

a numeric vector giving the vibration frequency in Hz of the masking stimulus. Either 32Hz or 0 (no vibration - control condition)

faster

The proportion of trials in which the comparison stimulus was judged as faster than the reference

slower

The proportion of trials in which the comparison stimulus was judged as slower than the reference

Original data were published in Dallmann et al. (2015).
