How personality traits, sports anxiety, and general imagery could influence the physiological response measured by SCL to imagined situations in sports?

The data were collected to understand how individual differences in personality (e.g. neuroticism), general imagery, and situational sports anxiety are linked to arousal measuring with skin conductance level (SCL) in situational imagery (as scripted for sport-related scenes). Thirty persons participated in the study, aged between 14 and 42 years, with sports experience ranging between 2 and 20 years, representing different sports disciplines and levels: international level, national level, regional and local level. In the study three questionnaires were used: the Imagination in Sport Questionnaire (ISQ), the Sport Anxiety Scale (SAS), and the Big Five Inventory-Short (BFI-S). The research was based on SCL data, collected at a frequency of 40 Hz and expressed in units of microsiemens (μS). Subjects listened to a pre-recorded script and were then asked to imagine the scene they listened to for around one minute. The study used scripts for 6 sport-related scenes: "A slow start", "Fitness activity", "Start in the high-level championship", "Successful competition", "Training session", and "Your 'home' venue". All collected data were properly inspected and preprocessed. The predictive regression model, based on artificial intelligence methods was constructed by relying on the theoretical premises.
