Relationship between files: The Readme.txt file provides descriptions of the data in Tactile_Acuity_Data.csv file, and information about data collection. 3. Additional related data collected that was not included in the current data package: Piano experience survey data are not included for confidentiality purpose. The descriptive result of the piano experience survey is summarized below. 4. Are there multiple versions of the dataset? NO -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Three groups of subjects participated in the study: blind subjects, pianists with normal vision, and control subjects with normal vision (no piano experience). Pianists and control subjects were blindfolded during the test. Tactile acuity on the index finger of the dominant hand was measured with two types of symbols--dot patterns similar to braille (dot chart) and embossed Landolt C's (ring chart). During the test, the charts were placed on a table in front of the subject. The subject read the row containing the largest symbols first, and proceeded line by line to the smallest symbols. The subjects were tested twice on each chart, with half of them tested in the order dot-ring-dot-ring and the other half in the order ring-dot-ring-dot. The tests were not timed, and accuracy was stressed over speed. The session lasted one to two hours. 2. Methods for processing the data: The tactile acuity of each chart was the average value of the two tests. For pianists, the piano playing information was obtained from a piano experience survey. 3. Instrument- or software-specific information needed to interpret the data: NA 4. Standards and calibration information, if appropriate: NA 5. Environmental/experimental conditions: NA 6. Describe any quality-assurance procedures performed on the data: NA 7.

Most had been playing the piano since early childhood with the number of years of continuous playing ranging from 6 to 24 (mean = 16.8 years). Most reported substantial practice ranging from 2.19 hours per week to 42 hours per week (mean = 16.5 hours). Most of the older subjects were piano or school music teachers. Most of them had been playing since childhood with the number of years of playing ranging from 35 to 68 years (mean 56.4 years). Most reported substantial practice ranging from one hour per week to 20 hours per week (mean = 5.3 hours).
