Introduction: Exploring gender differences in cognitive abilities offers vital insights into human brain functioning. Methods: Our study utilized advanced techniques like magnetic resonance thermometry, standard working memory n-back tasks, and functional MRI to investigate if gender-based variations in brain temperature correlate with distinct neuronal responses and working memory capabilities. Results: We observed a significant decrease in average brain temperature in males during working memory tasks, a phenomenon not seen in females. Although changes in female brain temperature were significantly lower than in males, we found an inverse relationship between the absolute temperature change (ATC) and cognitive performance, alongside a correlation with blood oxygen level dependent (BOLD) signal change induced by neural activity. This suggests that in females, ATC is a crucial determinant for the link between cognitive performance and BOLD responses, a linkage not evident in males. However, we also observed additional female specific BOLD responses aligned with comparable task performance to that of males. Discussion: Our results suggest that females compensate for their brain's heightened temperature sensitivity by activating additional neuronal networks to support working memory. This study not only underscores the complexity of gender differences in cognitive processing but also opens new avenues for understanding how temperature fluctuations influence brain functionality.

background: Positive orientation (PO) is a hidden variable explaining a tendency to formulate global evaluations regarding one's self, life and the future. It is inherited to a large degree and it could be considered a common base for numerous aspects of subjective well-being. The self-concept, in turn, is a basic adaptation formed during individual experiences that is responsible for adjustment. The primary aim of the current study was to verify hypotheses about the significant relationship between PO and a "core self" (high self-concept clarity, low self-esteem contingency, low self-rumination), as well as the meditational role of the "core self" in the relation between PO and hedonic balance. participants and procedure: A group of 200 participants completed several measures referring to PO, self-concept and emotions. results: The canonical correlation analysis revealed PO to be a strong predictor of the adaptive features of the self-concept. Moreover, the tested models suggest that (1) self-concept clarity is a significant mediator between PO and hedonic balance, and (2) PO directly predicts only self-concept clarity, whereas its relations with self-esteem contingency and rumination are mediated by the self-knowledge structure. conclusions: These findings indicate that PO is an important and independent factor enhancing adaptive features of the self-concept structure as well as well-being.
