This repository contains datasets from two experimental studies investigating the effects of activating different relational selves on voice characteristics and personality impressions. The research was conducted at the University of Warsaw between 2024-2025.
The first study (N=95) examined differences between "Me with my teacher" and "Me with my friend" relational selves, while the second study (N=112) focused on "Me with my mother" and "Me with my friend" relational selves. In both studies, participants recorded voice messages after sequential activation of two relational selves (e.g., teacher-teacher, friend-friend, teacher-friend, friend-teacher in Study 1). Recordings were made using a Sony digital recorder (24 bit mono, 96000 Hz, WAV format) with a Shure WH20 headset microphone.
The datasets include acoustic measurements analyzed using PRAAT software, capturing parameters such as speech duration, speech rate, pitch characteristics (mean, range, standard deviation), intensity measures (mean, range, standard deviation), and degree of voice breaks. For each participant, these parameters were measured after each of two sequential relational self activations. In variable names, "first measurement" and "second measurement" indicate the measurement taken after the first or second relational self-activation.
Additionally, the data contains personality impressions rated by independent judges (48 raters in Study 1, 16 raters in Study 2). These ratings include assessments of Big Five personality traits using the Ten-Item Personality Inventory (TIPI), as well as ratings of self-esteem, intelligence, and voice attractiveness, which were measured using 1-item scales. Each voice sample was evaluated for both relational self conditions.
