“…Transformation of perceived territorial shape (boundaries) may be studied based on (1) directly investigated individual perceptions using Lynch-type mental maps (Lynch, 1960), when respondents are asked to draw their perceptions of a region at the map (Siwek & Kaňok, 2000;Semian, 2012;Šerý & Šimáček, 2012;Chalupa, 2015;Marek, 2015;Markeliuk, Gomaniuk, & Sarkisov, 2019;Marek, 2020b), (2) regional consciousness of population, asking people about their identification with the region, their knowledge on the region and attitudes to the region (Siwek & Kaňok, 2000;Šerý, 2014;Vaishar & Zapletalová, 2016;Melnychuk & Gnatiuk, 2018), and (3) markers of identity of a region -regional features (symbols and institutions) (Więckowski, 2021).…”
