Background: Flying accuracy is influenced by pilots' affective reactions to task demands. A better understanding of task-related emotions and flying performance is needed to enhance pilot training. Objective: Understand pilot trainees' performance and emotional dynamics (intensity, frequency and variability) based on training phase and difficulty…

This study explored the impact of oxidation-reduction reaction problem difficulty on university students' cognitive load using event-related potentials (ERPs). Forty-eight balanced low and high difficulty problems were designed. Fifteen undergraduate students majoring in chemistry (8 females and 7 males) participated in the study. Results…

The present study investigated the potential of writing in English as a foreign language (EFL) for language learning by manipulating cognitive task complexity based on related models and hypotheses. English essays written by 59 Chinese postgraduate EFL students from different subject areas were analysed with reference to writing complexity,…

Chulalongkorn University Language Institute (CULI) test was developed as a local standardised test of English for professional and international communication. To ensure that the CULI test fulfils its intended purposes, this study employed Kane's argument-based validation and Rasch measurement approaches to construct the validity argument for the…

Knowing what one knows and accurately monitoring one's own capacities and performance on a moment-to-moment basis are important determinants of task success. Individual differences in such metacognitive monitoring are well documented, but what determines an individual's monitoring accuracy in a particular context is yet to be fully understood. One…

In recent years, there has been growing interest in the use of data-driven learning (DDL) in L2 writing instruction. This paper examined whether and to what extent DDL activities could enhance the writing complexity, accuracy, and fluency (CAF) of 30 Thai EFL learners. The presentation of DDL in this study was hands-on concordancing with the…

Small but robust differences in cognition exist between the sexes in adult populations. Studying sex differences in children's cognition can bring insight into when, where and how these differences might emerge in development. Here, we focus on differences in working memory because of its importance in underpinning a wide range of complex…

It is important to define what an error in a question paper is so that there is a common understanding and to avoid people's own conceptions impacting upon the way in which they write or check question papers. We carried out an interview study to investigate our colleagues' definitions of error. We found that there is no single accepted definition…

A crucial component of mathematics curriculum in primary education is represented by the ability to solve arithmetic word problems. Previous studies investigated predominantly the cognitive factors underlying this skill, neglecting the role of emotional (e.g. math anxiety -- MA) and metacognitive aspects (e.g. perceived difficulty). Some findings…

Spoken English Competency (SEC) remains a critical weakness in English Proficiency (EP) of Chinese college students, particularly when compared with their English competency in writing and reading. Despite years of English learning since elementary school, Chinese college students often struggle to master SEC. Although previous studies have…

The current paper intends to exploit the Many Facet Rasch Model to investigate and compare the impact of situations (items) and raters on test takers' performance on the Written Discourse Completion Test (WDCT) and Discourse Self-Assessment Tests (DSAT). In this study, the participants were 110 English as a Foreign Language (EFL) students at…

Previous studies have explored the roles of metacognitive instruction and collaborative writing, separately, in English writing. Little attention has been paid to students' writing complexity, accuracy, and fluency (CAF). The present study aims to bridge this gap through investigating integrated writing performances based on the linguistic…

Task design features have different effects on second language (L2) production and can be adopted for different pedagogical purposes. However, the synergistic effects of task features were left unexplored in the extant task-based literature. The present study investigated the synergistic effects of two task design features, namely, prior knowledge…

Despite their importance, dynamic and diagnostic assessments (DigAs) have received little attention in phycological aspects of foreign language teaching and learning settings; therefore, this study compared the effects of dynamic and diagnostic assessment (DigA) on Afghan EFL learners' speaking fluency and accuracy (SFA), learning anxiety (LA),…

Fast and frugal heuristics have been used to model decision making in applied domains very effectively, suggesting that they could be used to improve applied decision making. We developed a fast and frugal heuristic for infantry decisions using experts from the British Army. This was able to predict around 80% of their decisions using three cues.…
