Pitch Test: High C - Overview

[edit | edit source]

This section provides a detailed analysis of synesthetic responses to the pitch High C, across six battery tests. Each test measured RGB values and associated Z-scores, examining the color outputs for consistency and outliers.

Test Data Overview

[edit | edit source]

Data Set Analysis: For each test, the average (mean) and standard deviation (STD) of RGB values were calculated to determine central tendencies and variation in the data.

Distance Calculations: Relative Distances- Calculated as the absolute difference between the current and previous RGB values, normalized by 255 to express the difference as a percentage.

Z-Score Calculation: Z-scores were used to measure how far each RGB value deviates from the average, helping to identify outliers.

Normalized Distribution: Each RGB value was normalized to a scale between 0 and 1 using the minimum and maximum values of the dataset.

Closeness to Target Color (Euclidean Distance) Calculated to measure the distance between each test result and the corrected average (target color). If the distance was less than 30%, the result was classified as “Close”; otherwise, it was classified as “Off.”

Geometric Distance Results

[edit | edit source]

Pass/Fail Classification: Texsyn Toolbox Method-Tests are evaluated based on Euclidean distances. If the total distance is less than 1, the test is classified as “Pass,” and if greater than 1, the test is classified as “Fail.” This method aligns with the Synesthesia Battery / Texsyn Toolbox. https://synesthete.ircn.jp/files/EaglemanetalSynesthesiaBattery2006.pdf

Outlier Identification and Trend Analysis: Outliers are analyzed separately to explore possible patterns or relationships between pitch proximity and color, considering color blindness and relative pitch shifts.
