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 Qom province 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.
