The influence of extreme response style on sound evaluations
* Presenting author
This paper is the first to examine the influence of sociodemographic characteristics of listeners on the tendency to extreme response style (ERS) in psychoacoustical experiments. ERS can be described as the proneness to exploit the edges of rating scales in quantitative surveys leading to systematic deviations of the respondents' reported values from the true values.In line with the psychological literature, we assumed that ERS is more pronounced in women (compared to men) and persons with low educational level (compared to higher educated persons). Furthermore, we expected that ERS increases with ascending age of people and increasing survey duration. To test our hypotheses, we re-analyzised the data obtained by Weinzierl et al. (2018). In their study, 190 subjects rated their acoustical impression of 35 binaurally simulated rooms by means of the Room Acoustical Quality Inventory (RAQI). Results of linear mixed-effect models confirmed our assumption that women show a significantly higher tendency of ERS than men and that increasing survey duration leads to a higher ERS. In contrast, no significant influences of education and age on ERS were observed. The results highlight the role of ERS in sound evaluations and the need to consider this moderating factor when conducting psychoacoustical experiments.
