Abstract
This study investigated the degree of cortical arousal of the forehead during working memory performance in personality dimension of anxiety. Based on Gray’s definition of personality dimension of anxiety, in a pseudo-empirical study a sample of female students (n=793) aged from 18 to 28 years old completed Eysenck Personality Questionnaire and Carver and White’s Approach/Avoidance scale. 15 subjects whose scores were simultaneously in the upper distribution of Neuroticism and lower distribution of Extraversion (N+E-) were selected as high trait anxiety group (Anx+), and low trait anxiety group (Anx-) consisted of 15 subjects with higher scores of Extraversion and lower scores of Neuroticism (N-E+). Then their EEG was taken in baseline mode and while performing working memory task. Total scores in 1-back working memory task were taken as the indicator of working memory performance and EEG alpha oscillation during 1-back task was taken as cortical arousal index. Data were analyzed using T-test for independent samples. Results revealed that high trait anxious subjects showed more arousability in their right and left cortex of forehead during working memory performance, while their performance in working memory tasks was impaired in comparison with low trait anxious group. These Results supported Processing Efficiency Theory, which means although high trait anxious individuals employed higher mental effort during executive functions, their processing efficiency was impaired.

Abstract
The aim of the present study was to explain the structural model of adolescent goal orientation based on emotional schemas and working memory processing in the context of mental health. This study was descriptive-correlational and conducted with a structural equation modeling approach. The statistical population included all second-year high school students in the academic year 1403-1404, of which 315 were selected using convenience sampling, and after applying the inclusion and exclusion criteria, the data of 300 people were included in the analysis. The data collection tools included the Elliott and McGregor Goal Orientation Questionnaire (2001), the Leahy Emotional Schema Scale (2002), and the Nelson Cowen Working Memory Scale (2005). The data were analyzed using the structural equation modeling method and PLS software. The findings showed that emotional schemas and working memory both directly and positively affect different dimensions of achievement goal orientation, and working memory plays a significant mediating role in the relationship between emotional schemas and achievement goals. The proposed model had a good fit. The results of this study emphasize the simultaneous importance of emotional and cognitive factors in the formation of adolescents' achievement goals and can be a guide for educational and psychological interventions to improve their academic motivation.

Abstract

The present study aimed to investigate the mediating role of emotional working memory in the relationship between attentional bias and depressive symptoms within the context of family interactions. Guided by contemporary cognitive–emotional models of depression, the study explored how negative attentional bias, as a core vulnerability factor, may influence depressive symptomatology through impairments in emotional working memory, and how these processes are embedded in the dynamics of family relationships. This research employed a descriptive-correlational design using structural equation modeling (SEM). The statistical population consisted of adults aged 20–40 years living in active family systems in Tehran in 2025. A total of 350 participants were selected through purposive convenient sampling following eligibility screening. Research instruments included measures of depressive symptoms, attentional bias, emotional working memory performance, and family interaction patterns. The results demonstrated that negative attentional bias significantly predicted higher levels of depressive symptoms both directly and indirectly. Emotional working memory showed a significant mediating role, indicating that deficits in maintaining, updating, and regulating emotional information constitute a key mechanism linking attentional bias to depressive experiences. Furthermore, family interactions functioned as an amplifying contextual factor: maladaptive and conflictual family environments strengthened the indirect pathway by increasing cognitive–emotional load and reducing regulatory resources. The final structural model showed acceptable fit indices and supported the hypothesized mediational relationships. Overall, the findings highlight the importance of integrating cognitive, emotional, and contextual variables in understanding depressive symptoms. They also underscore the potential value of interventions targeting attentional processing biases and emotional working memory capacities, particularly within family-based therapeutic frameworks.
