Abstract
<jats:p>Introduction. Work performance of production workers is associated with self-regulation of psychological states. This study explores the dynamics of functional structures of mental regulation of psychological states of production workers during the work week and examines the relationships between psychological states and mental structures, as well as self-regulatory measures. Methods. The study sample comprised 62 production workers (17 males and 45 females, M = 34, σ = 6.7). At the beginning of the study, the characteristics of respondents’ mental structures (self-attitude, meaningfulness in life, and reflection) were identified. Afterwards, during the week, their psychological states and self-regulatory measures were assessed. Results. Production workers most often experience states of optimal mental performance at the beginning (74%) and end of the work week (71%). The incidence of high-intensity negative psychological states (tension, anxiety) increases from Monday to Thursday and then decreases. The highest incidence of low-intensity negative states (fatigue, drowsiness) occurs on Monday (23%) and Friday (16%). The maximum number of self-regulatory measures is observed in the middle of the work week. Specific patterns of the involvement of mental regulation indicators and regulatory measures in changes in psychological states during the weekly cycle were identified. Discussion. The study found that the increase in high- and low-intensity unbalanced states that reduce work productivity in the middle and end of the work week is compensated by increased regulatory activity among employees. The greatest involvement of indicators of mental structure and regulatory measures in self-regulation of psychological states is characteristic of the beginning and end of the work week. The main indicators of mental regulation of states during the work week are indicators of meaningfulness of life (life purpose and outcome), self-attitude (self-management) and employee overall reflection.</jats:p>
