Abstract
Socio-emotional development is one of the fundamental bases of individual and social health. The present study aims to investigate the developmental trajectory of socio-emotional tendencies (SET) and its components in preschoolers. Our sample was 447 healthy Iranian preschoolers (girl=47.4%) aged 48-78 month-old (mean=66.57, SD=6.79). they were from Tehran, Bandar Abbas, Mashhad, Zarand, and Tabriz as the representative provinces of the Iranian population, based on the geographical distribution and socioeconomic status. We used the Persian version of the Kindergarten Inventory of Social-Emotional Tendencies (KIST) which consists of six components. It included hyperactivity-maladaptive behavior, social skills, communication skills, daily living skills, eating behavior, and separation anxiety symptoms.
We used Kruskal-Wallis test to investigate the developmental trajectory of SET. Results showed that there were significant changes in daily living skills and separation anxiety symptoms during 6-month periods, meanwhile there were no significant changes in the other four components and SET in total. Then, the Games-Howell post-hoc test was performed to follow up the observed differences among age categories. Results of the present study showed that SET doesn’t change significantly in early childhood. It propose that the critical period of the socio-emotional ability development occurs sooner or later

Abstract
This study aimed to comparison of the effect of Transcranial Direct Current Stimulation (tDCS) and Transcranial Random Noise Stimulation (tRNS) combined with cognitive training on working memory performance of people with attention deficit/hyperactivity disorder. For this purpose, 45 children with attention deficit hyperactivity disorder in zahedan city were purposefully selected as the research sample. Subjects were divided into three groups: tDCS, tRNS and placebo group. Subjects in the experimental groups received 5 sessions of electrical stimulation (tDCS and tRNS) with an interval of 24 hours between each session; placebo group also received fake stimulation (non-effective). At the same time, all subjects also received cognitive rehabilitation of working memory. All subjects were evaluated before and after the stimulation and one week after the stimulation using the N-back task and the Wechsler Digit span test. The data were analyzed using repeated measures analysis of variance. The results showed that in the tDCS group, there was a significant difference in most working memory components from the pre-test stage to the follow-up (p<0.001). In the tRNS group, a significant difference was found in the component of direct digit span and reverse digit span in the research stages. In the comparison between the two experimental groups, the effectiveness of the tDCS group was higher than that of the tRNS group. Also, no significant difference was found in most of the components between the tRNS and placebo groups (p>0.05). Overall, the results of this study show that tDCS was more effective than tRNS in working memory and this method can be used together with other treatments to improve the working memory of children with attention deficit/hyperactivity disorder.
