The study aims to reveal autism vectors that are inherent in 3-4-year-olds with ASD. Three hundred eighty-three children with ASD took part in the research. An online questionnaire developed earlier by our research group was used. In the first stage, with the repeated use of exploratory factor analysis, the task of identifying the simplest factor s...

Previous literature highlights the potential of ICT use to enhance mathematical learning. There are also several theoretical arguments supporting that gifted education benefits from ICT use. However, empirical studies have paid little attention to the relationship between ICT use and gifted students’ mathematics performance. It is also unclear whet...

Iconic words constitute an integral part of the lexicon of a language, exhibiting form-meaning resemblance. Over the course of time, semantic and phonetic transformations “weaken” the degree of iconicity of a word. This iconicity loss is known as the process of de-iconization, which is divided into four stages, and, at each consecutive stage, the d...

В статье изложены результаты исследования особенностей визуального опознания русскоязычных звукоизобразительных (ЗИ) слов носителями языка (N = 106) с помощью метода «Методика принятия лексического решения». Каждому испытуемому было предъявлено 128 стимулов, из которых 64 являлись не-словами и 64 — целевыми стимулами. Целевые стимулы в равных част...

Background: Autistic spectrum disorder (ASD) is a significant socio-biological problem due to its wide prevalence and negative outcomes. In the current study, we aimed to develop an autism scale for early and accurate differentiation of 3- to 4-year-olds at risk for ASD since there is no systematic monitoring of young children in Russia yet. Method...

The study of iconicity, i.e., of a link between form and meaning in a word based on similarity, has gained increased attention in recent years. Although recent research has shown an important role of iconicity for first language acquisition, its role for the second language (L2) acquisition is still unclear, neither is it understood how the percept...

This article focuses on the effect of urbanization on violent crime – particularly homicide– in Costa Rica. Although violence is a major problem throughout Latin America, few empirical studies carried out in the area use high-quality socioeconomic and crime databases with a high level of geographical disaggregation. In this article, we employ data...

Intr oduction. The present article is aiming to describe the procedure of stimuli selection for the psycho-semantic experiment on visual perception of imitative words in native (Russian) and non-native language (English). The methodology of the experiment is predominantly based on the implementation of the “lexical decision” method. Thus, the aim o...

Objective: This study investigates the connection between crime rates and victimization by peer physical aggression in Costa Rican schools. Although previous research has demonstrated that peer victimization is related to community crime, no study to date has examined its association with homicides and drug trafficking, two criminal offenses that a...

Background: computer-based screenings are usually used for early detection of a child's mental development problems. However, there are no such screenings in Russia yet. This study aimed to elaborate scales for rapid monitoring of mental development of 3-year-olds. Methods: 863 children took part in the study, among them 814 children of the grou...

Psychodiagnostics of the risk for developmental delay in preschool children. The monograph presents the procedure and results of the screening scales development aimed to identify the risk for developmental delay in 3-6-year-old ichildren. Empirical indicators of developmental delay in preschoolers were identified using mathematical modeling meth...

Background. Sound symbolism (SS) refers to the direct association between the sound and the meaning of a word. The results of cross-linguistic research prove that SS is universal for different languages and cultures. Thirty percent of all natural languages consist of SS words. But despite the large number of psychosemantic studies which have been c...

Background. While various screening systems are used worldwide for early detection of developmental delay (DD), Russia still does not have such a screening system in place, even though a good prognosis for the cognitive development of a child with DD depend strongly on the time of the diagnosis. Objective. Te objective of this study was to create a...

Diagnosis of problems in mental development of children is the most actual at the early age. The sooner there is clarity about developmental delay (DD), the more effective is rehabilitation. The aim of the study was to identify predictive markers (PM) of DD in four-year-olds, according to following criteria. PM should be based on easily diagnosed i...

The present paper investigates the study of features of brain activity by the process of change the regimes of information associated with the stages of understanding of the meaning of visually presented texts in adult subjects (n = 148). Researchers have developed an original methodology of step-by-step presentation of the texts. This technology h...

The characteristic features of brain activity under variation of the information regimes associated with the stages of understanding visually presented texts in adult subjects (n = 148) have been studied. An original methodology for step-by-step presentation of texts has been developed in order to “detect” the psychophysiological markers of differe...
