The article explores the value orientations typical of residents in monotowns, i.e., single-industry towns. The linguistic data were obtained from an indirect associative experiment through an analysis of stimulusresponse speech acts. The methods from corpus linguistics and psycholinguistics made it possible to identify the hierarchical framework of key values in the consciousness of respondents from the diamond mining town of Mirny, Republic of Sakha. The core values included health, family, love, friendship, and security, as well as their semantic associations. The methodology for calculating speech act characteristics included the intersection index (O – Number of Overlapping Associates) and intersection strength (OSG – Overlapping Associate Strength), which reflected the psychological proximity of value meanings in communicative practices. The method revealed the integrative and regulatory role of values based on parameters of speech acts as social actions. The results show how language captures and transmits value orientations, reflecting both universal and ethnocultural perceptions. The findings contribute to the development of interdisciplinary linguistics, enhancing the understanding of value system in single-industry settlements. The method can be used for social planning, academic programs, and cross-cultural studies.
