Abstract
Obesity is one of the most important problems which threatens the global health. Healthcare organizations spend a
large amount of money to predict and treat obesity every year. The most common treatment for obesity is
concentrated on shaping a new lifestyle with more exercise and healthy diet. But a multitude of dieters fail. In this study, the role of cognitive processing in dieters` success or fail was investigated. Participants were
successful (N= 42) and unsuccessful (N= 45) dieters between 18 and 40 years old. Attentional bias, positive
implicit association, and working memory capacity were measured by dot-probe task, a modified
version of implicit association test (IAT), and N-Back task. Results indicated that unsuccessful dieters showed
greater attentional bias to (d= 0.69) and more food preferences for (d= 1.06) high-calorie food pictures.
Nevertheless, there was no significant difference in implicit associations for high calorie food and in working memory capacity between the groups. These results were congruent with some previous studies and they were discussed based on dual-processing model.

Abstract
| Integrated approaches try to connect different constructs in different theories and reinterpret them using a common conceptual framework. In this research, using the concept of processing levels, an integrated, three-level model of the cognitive systems has been proposed. In order to build an integrative framework for systematic interpretation of cognitive tests results, processing levels are divided into three categories of Feature-Oriented, Semantic and Conceptual Level. Since nervous system picks stimuli based on their features, processing levels in this framework is categorized based on the volume of stimuli's information, while Semantic network relates Feature-Oriented and Self-Oriented levels. To assessment the model quantitatively, 207 participants with impaired valance system from psychological clinics in Mashhad were selected by available sampling method. Participants' cognitive function was measured by The Beck Depression Inventory II, Semantic Distance Test, Verbal Fluency Test, Dot Probe Test, Stroop Test, Implicit Association Test and Wisconsin Card Sorting Test. Tets scores were organized as predictive variables, and the three processing levels were considered as mediating variables. The model's structure was analyzed through Structural Equation Model method with an exploratory approach. The best fitted model of data confirmed the three-level division of the research data. In this model, the path coefficient between semantic and conceptual constructions obtained 0.4. These results suggest that Feature-Oriented, Semantic, and Conceptual levels of cognition are differently processed, and cognitive tests results could be compared just in similar level according to the information volume of stimuli used. In previous studies, the relationship between Verbal Fluency test scores and the severity of Beck depressive score has often been controversial. Using the concept of processing levels, the relationship between these two variables have been reinterpreted. |

Abstract:
The present study was conducted with the aim of evaluating the effectiveness of the educational package of basic psychological processes on improving the processing speed and mathematical progress of elementary school students with learning disabilities in mathematics. The research method was quasi-experimental with a pre-test-post-test design with a control group. The statistical population of this research included all female students with second grade math disorder who have referred to Tolu Qain Special Learning Difficulties Training Center in the academic year of 1400-1399, the total number of these students was 20, which is a sample They were randomly placed in two experimental and control groups. Prepare worksheets in 20 different areas of psychological processes and the experimental group was trained for 20 sessions of 45 minutes, while the control group did not receive any training. To collect data, the processing speed subscale of the fourth edition of the Wechsler Intelligence Scale for children (Wechsler, 2003), the Iran KIMAT math test, and two tests developed by the researcher of the Mathematical Progress (Qorbanpour, 2019) were used. Data were analyzed using multivariate analysis of covariance. The obtained results showed a significant difference between the two experimental and control groups in the post-test. This means that education has been effective in improving the processing speed and math progress of students with math disorders. Based on the obtained results, paying attention to the educational strategies of basic psychological processes can lead to promising results in the education and rehabilitation of students with learning disabilities, and it can be used as an effective intervention method.
