Exploring Emotion Recognition Patterns Among Iranian People Using CANTAB as an Approved Neuro-Psychological Assessment.

Introduction: Emotion recognition is the main component of social cognition and has various patterns in different cultures and nationalities. The present study aimed to investigate emotion recognition patterns among Iranians using the Cambridge neuro-psychological test automated battery (CANTAB) as a valid neuropsychological test. Methods: In this descriptive-analytical study, 117 males and females (Mean±SD of age 32.1±6.4) were initially assessed by computerized intelligence and progressive matrices of RAVEN-2. Furthermore, the excitement recognition subtest taken from the Cambridge neuro-psychological test automated battery (CANTAB) was performed. The correct response of participants to each of the six basic emotions as well as the recognition time was used for analysis. Results: The maximum correct response rate was 75.83% related to happy emotion. The correct responses for sadness, surprise, disgust, anger, and fear were 70%, 68.48%, 47.84%, 42.54%, and 38.26%, respectively. Moreover, the shortest recognition time was related to disgust at 322 ms, while sadness with a mean response time of 1800 ms and fear response time at 1529 ms indicated the longest recognition time. In addition, participants recognized happiness with a mean response time of 1264 ms better than other emotions; however, post-hoc t-test analyses showed that only the correct responses for sadness and surprised emotions did not differ significantly, (t(112)=-0.59, P=0.55, d=0.05). These results suggested that different emotions have various correct responses. However, sadness and surprise did not differ. Conclusion: The findings of this study could be beneficial for evaluating cognitive elements, as well as cognitive abilities and inabilities among the Iranian population. Moreover, the findings could be used for investigating social cognition in this population. Highlights: Emotion recognition patterns among Iranians were investigated using a valid neuropsychological test.Iranians showed higher accuracy in recognizing happiness and lower accuracy in recognizing fear.Disgust was recognized with the shortest response time, while sadness and fear had the longest recognition time.The findings highlight cultural differences in emotion recognition and can aid in evaluating cognitive abilities and social cognition in the Iranian population.The study emphasizes the importance of considering cultural factors in assessing and understanding emotion recognition. Plain Language Summary: Understanding how people recognize emotions is crucial for effective communication and building social connections. However, the ability to recognize emotions can vary across cultures. This study aimed to investigate how Iranians recognize emotions using a reliable test. The researchers assessed 117 Iranian adults, both males and females, using a computer-based test. Participants were asked to identify six basic emotions (happiness, sadness, anger, disgust, fear, and surprise) displayed on a screen. The researchers measured the participants' accuracy in identifying each emotion and the time it took them to recognize it. The findings revealed that Iranians were most accurate in recognizing happiness and least accurate in recognizing fear. They were better at identifying positive emotions like happiness and surprise compared to negative emotions like disgust and anger. Participants took the least time to recognize disgust and the longest time to recognize sadness and fear. These results show that Iranians have specific patterns in recognizing emotions, which can be influenced by cultural factors. Understanding these patterns is important for assessing cognitive abilities and social cognition in the Iranian population. Moreover, these findings have broader implications. They highlight the need to consider cultural differences in emotion recognition, as it can impact communication and social interactions. The study's outcomes can be valuable for various applications. For instance, they can aid in developing tests to assess emotion recognition difficulties in individuals with conditions such as autism or schizophrenia. Furthermore, these findings can be useful for professionals, such as employees in customer service or mental health providers, who need to accurately interpret others' emotions. By shedding light on cultural variations in emotion recognition, this research contributes to our understanding of human emotions and their role in interpersonal relationships.

Evaluation of the Psychometric Properties of the Persian Version of Spence Children's Anxiety Scale in Iranian Adolescents.

The Spence Children's Anxiety Scale (SCAS) is a tool for measuring anxiety symptoms in children and adolescents. In this study, the psychometric properties of the Persian version of SCAS were investigated in an Iranian adolescents. This study was conducted on a sample of 684 adolescents. For standardization of SCAS, first- and second-order confirmatory factor analyses wereperformed. Also, to evaluate convergent and divergent validity, Fornell and Larcker criteria (1994), along with the Revised Children's Manifest Anxiety Scale (RCMAS)and Children's Depression Inventory (CDI), was used. A receiver operating characteristic (ROC) curve analysis was also performedto determine the cut-off point. The model fit of the correlated six-factor model was good however, a second-order model provided a statistically superior fit to the data. The reliability coefficients for the total scale and its dimensions were satisfactory (α > 0.7). Therefore, it can be concluded that the Persian version of SCAS has acceptable reliability and validity and can be used as a useful tool for early screening of anxiety in Iranian adolescents due to its easy use and specific design for children and adolescents.

Is online self-regulatory training effective in weight control? A pilot experiment on adolescence obesity during coronavirus-19 lockdown.

OBJECTIVE: Studies have shown that obesity is associated with decreased executive function. Impaired executive functions lead to poor self-regulation, which in turn may result in persistence of unhealthy behaviors, including eating behaviors, throughout life. Increasing self-regulation in childhood and adolescence has positive effects on creating healthy behaviors such as reducing unnecessary eating and changing unhealthy eating habits. The main purpose of this study is to evaluate an intervention package based on cognitive self-regulation training in changing eating behaviors and reducing obesity in children and adolescents. METHODS: Fifty-six students with obesity aged 12-16 years participated in the study in three groups (cognitive self-regulation training [CSRT], diet, and control). The CSRT group received twenty 30-min online training sessions with a diet over 10 weeks. The diet group received only a diet with no other intervention, and the control group did not receive any intervention. RESULTS: The results of our 2 × 3 repeated-measures ANOVA showed that the CSRT group had a mean BMI decrease of 2.21 (kg/m2 ) after ten weeks, and 3.24 (kg/m2 ) at the follow-up time. The diet group had a BMI decrease of 0.49 (kg/m2 ) at the ten weeks. In addition, the results showed that the CSRT had a significant reduction in eating behaviors such as external eating and emotional eating. However, the other two groups showed no changes in eating behaviors. CONCLUSIONS: Our results show that online cognitive self-regulation training has been effective in weight loss and eating behaviors. This study shows promising evidence for the efficacy of the online CSRT-training as a weight stabilization intervention in children with obesity.

Evaluation of the Psychometric Properties of the Persian Version of Children's Depression Inventory in Iranian Adolescents.

Objectives: Children's Depression Inventory (CDI) is a self-report tool for measuring depression in children and adolescents. In this study, the psychometric properties of the Persian version of CDI were investigated in an Iranian adolescent population. Methods: This study was conducted on a sample of 480 adolescent boys and girls in the age range of 12-18 years. The results showed that 23.6% of the study population were 11-13 years old, 62.1% were 14-16 years old, and 14.3% were 17-18 years old. Also, 48.5% of the sample were girls, and 51.5% were boys. To investigate the convergent and divergent validity, Beck's Depression Inventory-Second Edition (BDI-II) and Teenage Inventory of Social Skills were used, respectively. Results: The reliability coefficient of CDI, based on Cronbach's alpha, indicated the relatively high internal consistency of the items (0.907). The results of the exploratory factor analysis showed that CDI has a saturated factor, explaining 50.11% of the variance in the data. Also, goodness-of-fit indices of confirmatory factor analysis showed that the model is well suited for explaining depression. The present results also showed a negative correlation between children's depression and the social skills subscale and a positive correlation between children's depression and BDI-II score. Conclusions: The construct validity of the questionnaire was confirmed. It can be concluded that the Persian version of CDI has adequate reliability and validity. Therefore, it can be used as a useful tool for early screening of depression in adolescents due to its easy use and specific design for children and adolescents.

Exploratory and confirmatory factor analysis methods were applied for construct validity. RESULTS: Investigation of the psychometric properties of the Iranian version of CSI-24 showed its high reliability and confirmatory factor analysis results show the model's satisfactory fitting. CONCLUSION: The Persian version of CSI-24 is a useful self-report tool for evaluating the physical complaints of Iranian school adolescents aged between 12 and 18 years.

A novel CoFe2O4@Cr-MIL-101/Y zeolite ternary nanocomposite as a magnetically separable sonocatalyst for efficient sonodegradation of organic dye contaminants from water.

In this research, a novel magnetic sonocatalyst nanocomposite, CoFe2O4@Cr-MIL-101/Y zeolite, has been successfully fabricated employing a simple hydrothermal method. The as-prepared catalyst was thoroughly identified using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDS), EDS elemental dot-mapping, transmission electron microscopy (TEM), atomic force microscopy (AFM), vibrating sample magnetometer (VSM), and nitrogen Brunauer-Emmett-Teller (N2-BET) analyses. The procured CoFe2O4@Cr-MIL-101/Y nanocomposite was then assessed for the decomposition of three types of organic dyes namely methylene blue (MB), rhodamine B (RhB) and methyl orange (MO) from water solution using ultrasound irradiation and subsequently monitored via UV-Vis absorption technique. The sonodecomposition reactions of organic dyes were accomplished in the presence of the H2O2 solution as a green oxidizing agent. Furthermore, the influence of various experimental independent factors such as irradiation time, process type, initial dye concentration, catalyst dosage, H2O2 concentration, scavenger type, and catalyst regeneration on the decomposition of MB, RhB and MO were surveyed. Additionally, a first order kinetic model was applied to investigate the sonodecomposition reactions of dye contaminants. The rate constant (k) and half-life (t 1/2) data were gained as 0.0675 min-1 and 10.2666 min, respectively, for the decomposition of MB in the US/H2O2/CoFe2O4@Cr-MIL-101/Y system. Besides, evaluating the attained results, the distinctive performance of ˙OH as the radical scavenger originating from H2O2 throughout the sonodecomposition process is vividly approved.

Construction of magnetic MgFe2O4/CdS/MoS2 ternary nanocomposite supported on NaY zeolite and highly efficient sonocatalytic degradation of organic pollutants.

In this work, the novel magnetically separable NaY zeolite/MgFe2O4/CdS nanorods/MoS2 nanoflowers nanocomposite was successfully synthesized through the ultrasonic-assisted solvothermal approach. FESEM, EDAX, XRD, FTIR, TEM, AFM, VSM, N2-BET, UV-vis DRS and PL were utilized to identify the as-synthesized nanocomposite. Subsequently, the sonocatalytic activity of this nanocomposite was assessed in the degradation of organic dyes, including methylene blue (MB), rhodamine B (RhB) and methyl orange (MO) from water solutions for the first time. Several analytical parameters like irradiation time, process type, initial MB concentration, H2O2 concentration, catalyst dosage, organic dye type, and US power have been systematically investigated to attain the maximum sonocatalytic yield. Regarding the acquired data, the NaY/MgFe2O4/CdS NRs/MoS2 NFs sonocatalyst was incredibly able to completely eliminate the MB via engaging the US/H2O2 system. The kinetic evaluates demonstrated the sonodegradation reactions of the MB followed a first-order model. The apparent rate constant (k app) and half-life time (t 1/2) acquired for the sonodegradation process of MB utilizing the US/H2O2/NaY/MgFe2O4/CdS NRs/MoS2 NFs system were measured to be 1.162 min and 0.596 min-1, respectively. The free ˙OH radicals were also recognized as the main reactive oxygen species in the MB sonodegradation process under US irradiation. In addition, the outcomes of the recyclability study of the NaY/MgFe2O4/CdS NRs/MoS2 NFs sonocatalytic clearly displayed a less than 6% drop of the catalytic activity in up to four sequential runs. Lastly, a plausible mechanism for the sonodegradation reaction of organic dyes was suggested and discussed.

Psychometric Properties of the Abdominal Pain Index (API) in the Iranian Adolescent Population.

Considering the high prevalence of abdominal pain in children and adolescents in Iran, it is essential to use appropriate screening tools. One of the most comprehensive, yet concise, tools for this purpose is the Abdominal Pain Index (API). This study aimed to investigate the psychometric properties of the Persian version of the self-report API in adolescents. In this descriptive study, A total of 162 Iranian adolescents in the age range of 12 to 18 years were considered as the sample group, which included two groups of school students (n = 125) and adolescent patients with abdominal pain (n = 37). Clinical sample was selected by the available sampling method, and nonclinical sample was selected by the cluster sampling method. Adolescents in the sample group were selected from both clinical and nonclinical groups in order to evaluate differential validity. Instruments, including API, somatic symptoms subscale of the General Health Questionnaire (GHQ), and McGill Pain Questionnaire (MPQ), were also completed for the participants. Also, to evaluate the construct validity of API, exploratory and confirmatory factor analysis methods were applied. The exploratory factor analysis identified one general factor, and the confirmatory factor analysis results show the model's satisfactory fitting. Also, the researchers' hypothesis, i.e., API is a single-factor model (with five items), was approved. The reliability coefficient of the questionnaire was satisfactory for the total scale (α < 0.7). This study showed that API could be used with considerable confidence for Iranian children and adolescents with chronic pain.
