Abstract
Working memory is the comprehensive cognitive system that embedded attentional and memorial mechanisms and therefore can be used in systematic research of cognitive problems. Accordingly, the aim of this study was to investigate the developmental changes of working memory capacity, and its components, including phonological loop, visuospatial sketchpad, and central executive (inhibition and updating). A total of 356 children (8 and 12 years) recruited from primary school in Tehran were selected and tested. Digit Span, and the Kim Karad Visual Memory Test were used for measuring phonological loop and visuospatial sketchpad. Working memory capacity was measured by Backward Digit Span, and finally, the Stroop Task, and the Keep Track task measured central executive. Data analyzing showed as child growth, working memory and its components become more effective. More skills in arithmetic abilities, more flexibility in storage and processing, more experience in academic achievement and more use of metacognitive strategies can be possible reasons for the results of this study.

Abstract
Research and clinical observations demonstrate that anxiety is a prevalent mental health issue in children, impacting various aspects of their lives throughout different developmental stages. The aim of this study was to compare the effectiveness of mentalization-based therapy and parent-child relationship-based therapy in addressing executive functions and anxiety symptoms in anxious children. This research employed a semi-experimental design with pre-test, post-test, and follow-up assessments. The study's statistical population consisted of mothers of anxious children from the Bandar Abbas Oil Refining Company in 1402, with 45 eligible participants selected through available sampling and randomly assigned to two experimental groups and a control group. Assessment tools included Giova et al.'s behavioral rating questionnaires (2000) and the Spence-Parent Form children's anxiety scale (1998) administered at pre-test, post-test, and follow-up stages. Data analysis utilized SPSS 26 software, incorporating descriptive and inferential statistics. The results of the mixed variance analysis indicated a significant difference between the control group and the mentalization-based and relationship-based treatment groups regarding executive functions and anxiety symptoms in anxious children (P < 0.05). Both mentalization and parent-child relationship interventions contributed to reduced anxiety symptoms and improved executive functions in anxious children. Furthermore, parent-child relationship therapy demonstrated greater efficacy in alleviating anxiety symptoms compared to mentalization-based therapy. Consequently, based on the study's outcomes, it is plausible to consider mentalization and parent-child relationship interventions as appropriate strategies for enhancing executive functions and alleviating anxiety symptoms in anxious children.

Abstract
| This study aimed to investigate the effectiveness of compassion-focused and mindfulness-based cognitive-behavioral therapy (CBT), combined with physiotherapy, on psychological well-being and executive functions among elderly individuals suffering from chronic pain due to knee osteoarthritis. The research followed a quasi-experimental design with pretest, posttest, and follow-up assessments, along with a control group. The statistical population included elderly individuals over 60 years old diagnosed with chronic osteoarthritic pain, selected through purposive sampling. A total of 45 participants were randomly assigned to two intervention groups and one control group. The intervention groups received compassion-focused and mindfulness-based CBT, either with or without physiotherapy. Data were collected using Ryff’s Psychological Well-Being Scale and the Stroop Executive Function Test and analyzed using multivariate covariance analysis and Bonferroni post hoc tests. Findings indicated that the interventions, particularly the combined CBT with physiotherapy, significantly improved components of psychological well-being (self-acceptance, positive relations with others, autonomy) and executive functions. These effects remained stable at follow-up. Although improvements were observed in personal growth, environmental mastery, and purpose in life, no significant differences were found between the two intervention groups in these dimensions. Effect size analysis suggested a large clinical impact. Overall, the results support the integration of psychotherapy and physiotherapy as an effective approach to promoting mental health and cognitive functioning in elderly patients with chronic pain. |

Abstract
| Cognitive abilities are among the most important predictors of pilots’ precise performance. With this perspective, the present study aimed to identify the essential cognitive themes and skills for pilots and to propose a theoretical model accordingly. The study was conducted using a qualitative approach and a meta-synthesis method, following the seven-step model of Sandelowski and Barroso (2007). The research population included all scientific documents published over the past 26 years, retrieved from 7 international and 3 national databases, totaling 307 scientific documents. After an in-depth review, 23 documents were selected for final analysis. Data analysis was performed through thematic analysis, and to ensure research quality, the documents were carefully analyzed and the process thoroughly documented. Expert feedback was incorporated throughout the research steps. Additionally, the Critical Appraisal Skills Programme (CASP) checklist was employed to assess the quality of the selected documents and ensure the reliability of the study’s findings. The results proposed a conceptual model consisting of 11 main themes and 59 sub-themes. The main themes included: perceptual-motor abilities, working memory, attention and concentration performance, flexibility in information processing, sequencing/planning abilities, perceptual speed, decision-making/reasoning, perceptual-sensory skills, coordination, and psychomotor abilities.The findings of this study can be utilized to develop a comprehensive assessment tool as well as to design continuous and targeted training programs aimed at maintaining and enhancing pilots’ cognitive skills. |
