The aim of this study was to investigate the efficacy of acceptance and commitment therapy on perceptual and attitudinal body image in individuals with body dysmorphic disorder. The study was conducted with multiple baseline single subject design. Using purposed sampling, three participants were selected among the women with body dysmorphic disorder referred to the psychiatric clinics of Tabriz city in 2022. They were assessed by Attitudinal Body Image Questionnaires (MBSRQ) and Perceptual Body Image Questionnaire during the baseline, treatment and follow-up periods. They received an one-hour 8 sessions of Acceptance and Commitment Therapy. The findings of the research showed that acceptance and commitment therapy has a positive effect on attitudinal body image with an average reliability change index of 3.62 and recovery percentage of 58.66 and perceptual body image with an average reliability change index of 2.28 and recovery percentage of 62  in individuals with body dysmorphic disorder. The results of this research showed that Acceptance and Commitment Therapy can improve perceptual and attitudinal body image in individuals with body dysmorphic disorder. These findings have practical implications in clinical settings, which have been discussed.

Paying attention to users' emotional desires and facilitating user-product interaction have become an essential component in design, production and marketing. User experience includes user’s perceptions and feedback while using or anticipating the use of products. Optimizing user experience can increase the satisfaction of users, motivate customers to buy products and, consequently, improve the competitive position of manufacturers in the market. Product designers need to carefully identify and evaluate user’s needs in different groups of products to create different features, semantic, sensory, and behavioral functions in the product and improve the perceived user experience of the product. So far, different methods have been proposed to collect users' opinions and demands regarding different types of products. Surveying and focusing on groups are the traditional methods in market research, which have their own strengths and weaknesses. There are some integrated solutions proposed to solve problems by these methods. Designers and manufacturers face an urgent need to use the different proposed methods to accurately extract demands of users in practical examples, so that they can understand these methods and their application in real projects. This research seeks to identify the needs of users and evaluate the user experience with some types of these products. This research is based on a practical approach that applies the repertory grid technique to extract factors involved in user experience in everyday products for chopping onion. This technique is a semi-structured method to define different aspects of a phenomenon from the personal viewpoints of subjects by minimizing the possible biases of the researcher. Based on this, a case study of that technique is conducted to extract the factors involved in the user experience in everyday onion chopping tools. The implementation of the technique has three main stages including element selection, construct extraction, and identifying element relationship to constructs by using content analysis. For this purpose, by interviewing 20 users of onion chopping tools, a conceptual model was presented on the factors affecting user satisfaction in this category of products. The reason for choosing the onion chopping tool was the daily use of these tools, and the target population consisted of 20 to 40-year-old female users who did daily cooking activities. Seven elements were arranged based on the subjects' suggestions for onion chopping tools. The interview was conducted in a kitchen with the presence of the mentioned onion chopping tools, and the subjects were allowed to do onion chopping by any of the tools they wished. To discover the constructs, the elements were provided to the subjects in the form of triple comparisons, and then an in-depth interview was conducted. As many as 545 personal constructs were extracted in the initial stage. After the content analysis, they were reduced to 42 final constructs. The priority of the final constructs was extracted based on an online questionnaire, and the superiority of the elements was determined on the Likert scale. The obtained scores were entered and analyzed in the Idiogrid software version 2.4, and information was extracted in three stages including statistical information of structures, and statistical information of the elements and cognitive map of elements. Then, principal component analysis was done to understand the relationship between the structures and elements and their graphic expression showing the combination of the constructs and elements. In general, the range of the scores obtained in the structures was from 2.85 to 4.85, which has little dispersion according to the determined range (1 to 5). This result can indicate that the extracted structures have correctly identified the needs of users which are more or less important. Also, the results showed that the structures related to the safety criteria are the most important, and structures related to appearance and personal preferences of the subjects are the least important in this type of products. The results of the comparing the tools showed the strengths and weaknesses of each tool according to the extracted structures, the discovery of which will lead to the creation of new and optimized products. Since there are many dimensions in evaluating user-centric products, in order to achieve user’s satisfaction, it is necessary to pay attention to all of the effective items in user experience. The number and details of the structures obtained showed that the repertory grid technique can be used as a suitable solution for extracting the demands of users about different products. By using multiple comparisons, this method, brings up various cases in the minds of users, which are not expressed in traditional interview methods. Also, comparing the users of different products creates a situation that can include a wider range of user demands. This is the strong point of this method in comparison with the focus group method because, to uncover underlying hidden needs, approaching unusual or off-target users can provide an opportunity for product development.

Pornography is one of the addictive and high-risk sexual behaviors that can play a role in different dimensions of people's mental health. People involved in pornography addiction suffer from mental, emotional, cognitive problems which have a negative effect on their life.

The aim of this study was to investigating the General health status of people with pornography addiction: comparison with the normal group.

This research is a causal-comparative study. The statistical population of the present study includes all men aged 18 to 35 with pornography addiction and normal in Urmia city in the spring and summer of 2023.
The statistical population of the present study includes all men aged 18 to 35 in Urmia city in the spring and summer of 2023. To determine the sample size, by referring to the GPower sample size software, 36 people with pornography addiction and 36 people who did not have pornography addiction were selected using the available sampling method and completed the pornography addiction questionnaire of Kerr et al (2014) and Goldberg's & Hiller general health questionnaire (1972). The data was analyzed by multivariate analysis of variance and by SPSS 19 software.

The results showed that there was a significant difference between the two groups in anxiety and insomnia (P< 0.05) and depression (P< 0.01), but there was no significant difference between groups in somatic symptoms and and social dysfunction (P< 0.05).

According to the obtained results, it can be said that pornography addiction can lead to more depression, anxiety and and insomnia; Therefore, it is suggested to use preventive and therapeutic interventions to reduce the tendency to pornography in groups exposed to this addiction

The aim of this study was to determine effectiveness a training package for cool executive functions on the academic motivation of sixth grade elementary normal students in normal schools.

The research was performed by quasi -experimental method of pretest-posttest with control group. research Sample was Included 2 sixth grade classrooms from 2 different primary schools in Tabriz in the academic year 1397-98 that were selected by selecting multi-stage cluster method and randomly divided into two experimental and control groups. The experimental group was trained for 16 sessions. Data from the Academic Motivation Questionnaire in the pretest and posttest stages, were analyzed using statistical analysis of covariance.

The results showed that this package has been significantly effective in improving academic motivation, it significantly increases external and internal academic motivation and significantly reduces Lack of  motivation in the experimental group(p <0.001).

The findings generally confirmed the effectiveness of the educational package of cool executive functions on the academic motivation of sixth grade elementary students. Therefore, this educational package is recommended for training sixth grade elementary students.

The aim of this study was to determine the effect of Brainwave Entrainment in alpha band on working memory, anti-saccade and anxiety level of anxious participants. The present study is a quasi-experimental project of pre-test-post-test with control group. In this regard, after screening 250 university students, 30 anxious participants were selected by Beck anxiety inventory and randomly divided into one experimental group and one control group (15 groups each). All participants were assessed in the pre-test and post-test stages by the Corsi Blocks Tapping test, Antisaccade Task and Beck Anxiety inventory. Participants in the experimental groups received 10 Hz binaural beats for 30 minutes for 5 days a week in a period of one month. Data were analyzed using multivariate analysis of covariance. The findings showed that 10 Hz binaural beats (alpha bands) significantly improved pasticipant's working memory, increased antisaccade and decreased anxiety level. Therefore, brainwave entrainment in the alpha band is recommended as a non-invasive intervention method to reduce the level of anxiety and improve cognitive functions.

Human factors are critical in the design and development of various products, but wideness and unclarity of different aspects of these factors make it difficult to extract demands of users. Studying emotional aspects of users' behavior in interaction with products, as well as interviewing them, is considered as an efficient tool in extracting design demands. This study aims to integrate the application of task analysis and the measuring of emotional aspects to determine the users’ emotional states in the different stages; and therefore extract the user satisfaction criteria.

This research has a descriptive/ exploratory approach. In this practical study, the use of two everyday tools for chopping onions is analyzed. 20 users of these tools were non-randomly selected to participate in the test and interview. Users performed the task with each tool, and the process was recorded by a camera. After performing the task, subjects completed self-assessment questionnaire and then, an interview was conducted about their experience of the tools usage. Parametric t test was used to evaluate results of the questionnaire and compare averages.

Findings of the emotional questionnaire showed that the emotional states of people in different stages of task are significantly different from each other. The determined emotional states, showed the weaknesses and the advantages of the tools studied. By analyzing videos, interviews and surveys, users' demands were extracted. The extracted features were categorized based on the work steps.

Using this method can reveal precise details of users’ needs concerning product category, which can be used as a suitable tool for designers and researchers in the field of user experience.

The present study was conducted to determine the effectiveness of transcranial direct current stimulation on social-informational conformity, considering the moderating role of gender.

Two groups (male and female), each group consisting of 24 people aged 18-30, were selected from Tabriz University students' society with a non-random and available sampling method. The current research design was a semi-experimental type with a pre-test and a post-test. In the pre-test stage, the social-informational conformity computerized task was implemented. Then, two sessions (each, 20 minutes) of transcranial direct current stimulation were applied. In the post-test phase, the same social-informational conformity task was performed. Finally, the findings were analyzed with repeated measures variance analysis and covariance analysis in SPSS version 24 software.

The amount of social-informational conformity increased in both groups after applying transcranial direct current stimulation, and gender did not moderate the effect of this stimulation.

Transcranial direct current stimulation has the same effect on conformity in both men and women. Also, cathodal stimulation of the ventromedial prefrontal cortex significantly increases the tendency for social-informational conformity in women and men when the participants' initial decision is different from the majority. Since cathodal stimulation reduces neuronal firing, cortical excitability, and motor-evoked potentials, it is reasoned that the reduction of vmPFC stimulation enhances the conformity behavior in people.

The present study aimed to investigate the effects of different models of transcranial Direct Current Stimulation (tDCS) on risky decision-making in male team sports referees. Twenty four Football, Futsal, Vollyball, Basketball, and Hanbal referees aged 19-38 at level 3 to national level with 2-18 years of experience voluntarily took part in this study. After the familiarization session, in a double-blind, sham-controlled crossover design, each subject visited the laboratory on three different occasions separated by at least 72 hours in between and was exposed to anodal, cathodal, and sham stimulation types over the right dorsolateral prefrontal cortex (L-DLPFC). Before and after each stimulation type, Iowa Gambling Task (IGT) and Impulsivity (IMP) Go/No Go psychological tasks were performed. The difference between the mean values of the variables (Delta) at pre and post-intervention were calculated and used for statistical analyses. The results showed that delta IGT was significantly higher in Anodal and Cathodal stimulation compared to sham stimulation (p=0.003, p=0.01, respectively). On the other hand, a significantly higher delta IMP was observed in anodal and sham stimulation in comparison with cathodal stimulation (p=0.0001, p=0.002, respectively). As a novel finding, these results indicated the positive effects of anodal stimulations over the right DLPFC in factors associated with risky decision-making in male sports referees. To conclude, these results pave the path for using tDCS as a possible strategy to boost risky decision-making in male sport referees. However, more research is needed to ascertain this conjecture.

In psychophysics domain, various factors have been studied as the main account of the time contraction after stimulus repetition and the time expansion after a novel stimulus; however, there is no clear explanation about the amount of involvement of temporal and non-temporal features. In this study, 48 sub-jects participated in 3 experiments in which the purer role of temporal properties of stimului were examined. Data were provided by a tem-poral oddball paradigm and the analysis was implemented by repeated measures analysis of variance in experiments 1 and 3. In experiment 2, a psychometric function was used to deter-mine the modified estimations in temporal pro-cessing system. Findings showed that despite removing the non-temporal change in expe-riment 1, the temporal change between repea-ted/non-repeated stimuli can produce time con-traction and dilation respectively. The result was only for the auditory system. In experi-ment 2, an efficient threshold for temporal oddball was suggested. Using the updated threshold, experiment 3 revealed concordant repeated/non-repeated effects on time percep-tion in both modalities.

Repetition priming and repetition suppression are two phenomena that both are caused by repeated exposure to an identical stimulus. Repetition priming usually is under- lined by improved behavioral performance, whereas in timing, the repetition suppression is accompanied by increasing error in time two estimations. This study investigated the possible simultaneous concurrence of these phenomena. Twelve adult subjects participated in a temporal oddball task in which the repetition of standard stimuli was under experimental manipulation, compard to the target stimulus. Both changes in performance and time representation were analyzed by a repeated measure within group design. Repeated presentations of temporal stimulus either in visual or auditory modalities improved participants behavioral performance (repetition priming). At the same time, data analysis for time representation showed that despite different directions in the modalities, the oddball stimulus was able to distort the time representation, both in time contraction and time expantion. The findings proposed that although the repetition priming can lead to faster and more accurate response, but more time distortions after repeated stimuli can be explained by the shift occured in errors distribution.

To find principal factors which affect the development of enumeration, many recent researches have investigated the effect of visual characteristics on counting process. Here we have addressed the effect of arrangement on enumeration process.
37 participants aged between 18 to 30 years old were evaluated. We examined counting speed in three different arrangements of dots in five magnitudes (8-12) which differed in regularity and imaginary lattices between their dots.
According to our results, enumeration speed is affected by both arrangement and the set of magnitudes (p Taken together, these results show that lattice formation which facilitates groupitizing and subsequently subitizing, has considerable effect on enumeration speed. Meanwhile the more various strategies of groupitizing in arrangements will cause slower enumeration speed, but regularity of arrangements does not guarantee the accuracy of responses.

Counting is of the most basic mathematical abilities. Many researches have demonstrated that different perceptual abilities can affect counting skills. We investigated the impact of visual search (VS) and visuoumotor organization (VMO) on counting speed.
Material and A total of 40 people in two groups of borderline and normal intellectual ability (20 subjects in each group) participated in the study. Three areas were evaluated: (1) VS, (2) VMO, and (3) counting speed. We used three self-designed evaluation softwares to examine VS and counting speed. VMO was assessed by Loewenstein Occupational Therapy Cognitive Assessment.
We calculated the Pearson rank correlation in both groups, to investigate the relation between counting speed and two other variables. According to the results, the speed of counting was related to VMO (P Counting in different sets of objects is influenced by VMO and VS depending on their characteristics such as spatial distribution and the number of contents.

The present research investigated the effects of two different types of music on cardiovascular responses in essential hypertensive men in comparison with healthy men based on introversion and extraversion. One hundred and thirteen hypertensive men referred to Madani Heart Hospital in Tabriz completed the NEO-FFI Questionnaire and after obtaining acceptable scores were classified in four groups: introvert patients, extravert patients, introvert healthy subjects, and extravert healthy subjects (each group with 25 samples with age range 31-50). Baseline blood pressure and heart rate of each subject was recorded without any stimulus. Then subjects were exposed to slow-beat music and blood pressure and heart rate were recorded. After15 minute break, and a little cognitive task for distraction, subjects were exposed to fast-beat music and blood pressure and heart rate were recorded again. Multivariate analysis of covariance (MANCOVA) test showed that extravert patient subjects obtained greater reduction in systolic blood pressure and heart rate after presenting slow-beat music compared with introvert patients (P= 0.035, and P= 0.033 respectively). And extravert healthy subjects obtained greater reduction in heart rate after presenting slow-beat music compared with introvert healthy subjects (P= 0.036). However, there are no significant differences between introvert and extravert groups in systolic and diastolic blood pressure and heart rate after presenting fast-beat music. Based on our results, introvert subjects experience negative emotions more than extravert subjects and negative emotions cause less change in blood pressure in these subjects compared with extravert subjects.
