Classroom-based language assessment (CBLA) in the Indonesian context has become more significant since the shift of the assessment model from summative based assessment (Ujian Nasional or the final exam) to formative-based assessment (Asesmen Kompetensi Minimum (AKM); therefore, teachers need to develop their classroom-based language assessment literacy (CBLAL). The model places a greater emphasis on students' learning outcomes in class rather than final test scores. This study aims to examine the CBLAL level of experienced and novice EFL teachers, their perceptions of CBLAL, and their needs f

Abstract Background Marital relationships, like any other interpersonal bond, encompass both positive and negative dimensions. Central to the success of marriage is the level of satisfaction and commitment experienced by the partners. This study aims to compare the efficacy of cognitive-behavioral couple therapy and schema-based couple therapy in reducing the desire for divorce and marital boredom. Methods This experimental study employed a pre-test-post-test design with a control group. The research sample comprised couples experiencing marital issues who sought counseling at various counseli

Socially anxious individuals are very sensitive to threatening information in the environment, so visual working memory (VWM) is of great significance for them. However, the influence of social anxiety on VWM is unclear. In the present study, we aimed to investigate the VWM in individuals with social anxiety using electrophysiological techniques. Event-related potentials (ERPs) of high socially anxious (HSA) individuals and low socially anxious (LSA) individuals were recorded during a change-detection task with two memory conditions (two and four items).

According to the social heuristics hypothesis, people intuitively cooperate or defect depending on which behavior is beneficial in their interactions. If cooperation is beneficial, people intuitively cooperate, but if defection is beneficial, they intuitively defect. However, deliberation promotes defection. Here, we tested two novel predictions regarding the role of trust in the social heuristics hypothesis. First, whether trust promotes intuitive cooperation. Second, whether preferring to think intuitively or deliberatively moderates the effect of trust on cooperation. In addition, we examin
