Abstract

The transformation of religious values in the digital era has become an interesting phenomenon, especially for teenagers who are actively using technology. This study aims to analyze how religious values are internalized, modified, and applied in the digital lives of adolescents. With a qualitative approach, data is collected through in-depth interviews, observations, and literature studies. The results of the study show that adolescents use digital platforms to learn religion, such as taking online studies, reading religious articles, and discussing in online forums. However, there are challenges in the form of the dissemination of invalid information and the negative influence of social media on religiosity consistency. This study emphasizes the importance of guidance from families, educational institutions, and religious leaders in shaping healthy media consumption patterns and supporting the internalization of religious values.

Abstract

The meaning of language is influenced not only by linguistic structures, but also by the cognitive processes that occur in the human mind. This article discusses how cognitive processing, such as perception, memory, and reasoning, plays a role in the formation of language meaning. This study uses a theoretical approach that integrates cognitive linguistics with psychological science to explain the relationship between mental representation and meaning. The results of the study show that the formation of meaning is a dynamic process involving sensory experience, social context, and pragmatic use of language. This knowledge is expected to enrich insights into how humans understand and use language in various communication situations. The cognitive process in the formation of language meaning includes several main stages, namely sensing, storage in working memory, and interpretation based on context. This process depends on the mental schema that the individual has, which is acquired through social experiences and interactions. Cognitive processing is also influenced by factors such as cultural bias, individual experience, and level of familiarity with a language. Meaning is not static, but rather evolves over time and depends on the dynamics of communication. In linguistic interactions, individuals utilize mechanisms such as analogies and associations to understand new or complex meanings. Cognitive processes play an important role in the formation of language meaning. Meaning is determined not only by grammatical structure but also by the way individuals process information through experience and context. This research emphasizes the importance of a multidisciplinary approach to understanding the dynamics of meaning formation, which involves linguistics, psychology, and sociology. By understanding this process, we can improve strategies for language teaching, translation, and intercultural communication.

Abstract

This study investigates language disorders in individuals with autism from a psycholinguistic perspective, focusing on the cognitive and social factors that affect language development. Language disorders are a defining feature of Autism Spectrum Disorder (ASD), hindering effective communication and social interaction. The research examines pragmatic difficulties, semantic challenges, and the cognitive processing issues that individuals with autism experience, particularly in understanding and producing language. Through a qualitative approach, this study explores the relationship between these language disorders and psycholinguistic interventions that aim to improve communication skills. The results highlight the significance of targeted interventions, such as speech therapy and social communication training, in enhancing the ability of individuals with autism to engage in social interactions. The study concludes that while language disorders in autism cannot be completely cured, appropriate therapeutic methods can significantly improve language skills and social interactions. The implications of this research suggest that a psycholinguistic approach to autism language disorders can provide deeper insights into effective intervention strategies and improve communication abilities for individuals with ASD.

Abstract

Literature serves as a powerful medium for expressing human emotions, ideas, and experiences, with poetry, prose, and drama being the three primary genres. These genres are distinct in their characteristics, narrative structures, and techniques used to convey their messages. The purpose of this study is to explore the diverse expressions within poetry, prose, and drama, and to understand how they reflect and engage with the complexities of human life and society. A descriptive qualitative research method was applied, involving literature review, data collection from classical and modern literary works, and secondary sources such as theory books and journals. The results show that each genre uniquely portrays emotions, social issues, and human conflicts—poetry using symbolic language and rhythm, prose offering detailed narrative descriptions, and drama expressing tension through dialogue and performance. This study concludes that understanding the expressive qualities of these literary genres enhances our comprehension of human life, culture, and societal values, emphasizing their ongoing relevance in addressing contemporary issues.
