Effect of tone timbre on a delayed discrimination task

Abstract

Evaluating the skills required as minimum components for their structuring as competencies is an alternative in the analysis of behavioral competencies and functional aptitudes. This work evaluated the discrimination skill using a delayed pitch discrimination task in the context of the domain of initiation in music and ear training. A tone discrimination task was programmed with an interval between stimuli of 20s to evaluate the effect of two types of timbre (i.e., pure tone and human voice) on the percentage of correct answers in the task. 30 female students with an average age of 22 years participated. The results showed higher scores to human voice timbre compared to the pure tone. The results are discussed in relation to previous studies and interpreted in terms of linguistic modes and their relation to pitch discrimination and pitch matching.
