TABLE 3.

Main results from ordinal logistic regression of semitone off values on the four condition variables: performer (self vs. other), instrument (own oboe vs. other oboe), transposition (original vs. pitch-shifted), and motor interference (no interference vs. motor interference), separately for Oboist 1 and Oboist 2.

To save space, statistics for the intercept terms (6 for Oboist 1 and 11 for Oboist 2) are not shown here. Confidence intervals were obtained by profiling the likelihood function, and p-values were calculated by comparing the t-values against the standard normal distribution. ^∗indicates significance at α = 0.05.
