Abstract

This research aims to examine the structure and access of the mental lexicon in human memory through the psycholinguistic approach. The current study utilizes the qualitative descriptive approach by conducting a systematic literature review. The result shows that the access of the lexical knowledge is not constant, considering the frequency of the word, the contextual cue, and the meaning relationship, because it affects the language comprehension and production. The result also shows that the mental lexicon is hierarchically organized for effective lexical retrieval when people use language. This article concludes that the knowledge of the structure and the access of the mental lexicon is very significant for language acquisition processes and for the analysis of language disorders, including aphasia and dyslexia.

Abstract

The rapid development of Artificial Intelligence (AI), particularly Natural Language Processing (NLP), has brought together two fundamental disciplines: Psycholinguistics and Computer Science. This research seeks to bridge the theoretical gap between how the human brain processes and generates language (psycholinguistics) and how machines model and replicate these processes (AI). This research employed a comparative-analytical literature review. Data was collected from leading academic journals focused on AI language models (such as Transformer and Large Language Models/LLMs) and theories of human language processing (such as Serial Processing and Connectionist Models). The analysis focused on three main dimensions: lexicon acquisition, syntactic processing, and pragmatic understanding. It was found that while modern AI excels at predicting word order and syntactic structure based on probability (like statistical approaches in cognition), it still falls short of fully replicating semantic processing tied to experience, awareness, and social context (a hallmark of human processing). Current AI models demonstrate impressive speeds in lexical inference but often fail at tasks requiring a theory of mind or a multi-layered understanding of pragmatics. Integrating psycholinguistic principles into AI architectures holds great potential for developing systems that are not only efficient but also more natural and human-like in their interactions. Further research is needed to build AI models that reflect the complex bottom-up and top-down processes in the human brain.

Abstract

The Independent Curriculum requires teachers to be more independent, creative, and responsive to students' needs. However, there are still many teachers who do not have optimal competence in implementing it. This is exacerbated by the leadership of the principal who has not fully played the role of a mentor and motivator and the implementation of academic supervision which is still a formality and has not touched on aspects of professional development in depth. As a result, the process of teachers adapting to the Independent Curriculum is slow and uneven. This research uses a library research approach. The data used in this study were sourced from literature in the form of scientific articles and research reports discussing principal leadership, academic supervision, and teacher competency development. The results of the study indicate that: 1). Principal leadership plays a crucial role in improving teacher competency through support, motivation, and coaching that encourage teachers to be more prepared and capable of implementing the Independent Curriculum. 2). Academic supervision is carried out collaboratively and continuously through classroom observations, feedback, and coaching that helps teachers develop professionalism and understand the Independent Curriculum more deeply. 3). The synergy between leadership and supervision has proven to be an effective catalyst in accelerating teacher competency improvement, especially in adapting to the demands and principles of the Independent Curriculum. Thus, principal leadership and academic supervision have proven to have important and complementary roles in improving teacher competency in facing the Independent Curriculum. Supportive leadership and reflective supervision can create a learning environment that encourages teachers to develop professionally and pedagogically
