Cognitive load

Emotion and cognition are both considered influential factors in language learning. In this study, the role of "emotioncy" (which is a combination of emotion and frequency) in the cognitive load and sentence comprehension of a group of language learners was examined. Emotioncy includes emotions that are evoked by the senses. To this aim, 200 English as a foreign language (EFL) learners were asked to fill out the NASA Task Load Test, a sentence comprehension test, and an emotioncy scale. Confirmatory factor analysis (CFA) was run to measure the construct validity of the emotioncy scale. Subsequently, Pearson Product-Moment correlation coefficient and structural equation modeling (SEM) were used to analyze the data. The results showed that emotioncy has a significantly negative and positive relationship with cognitive load and sentence comprehension, respectively (p

Learning can only maintain its functional originality when it leads to permanent changes, and such changes are only possible if accompanied by self-explanation. The current study was conducted to investigate the effect of self-explanation and the solved examples on students’ transfer, intrinsic motivation, and cognitive load in English courses. It was an experiment in the form of a 2×2 generalized random block design. The population consisted of all 8th-grade students in Semnan, Iran, from whom 120 students were selected applying random sampling – by considering a figure for each student, writing each figure on a piece of paper, putting all inside a pack, mixing them together, and drawing one piece out each time to get 120 candidates. Teaching English was done using the “Solved Examples” method. The instruments applied  to collect the data included the Intrinsic Motivation Questionnaire by Kuvaus and Dysvik (2009), the Cognitive Load Questionnaire by Paas and van Merrienboer (1993), and the researcher-made questionnaire of near and far transfer. The statistical analysis of the data was conducted using the Two-way Analysis of Variance (ANOVA). The findings indicated that the format of presenting content (ordinary and erroneous solved examples) and self-explanation are correlated significantly with the near and far transfer, cognitive load, and intrinsic motivation (P<0.01). Based on the obtained results, it can be argued that self-explaining and presenting solved examples are useful strategies to enhance students’ transfer, intrinsic motivation, and cognitive load in learning English, and can be included in the curriculum of schools to empower students in solving intellectual problems.  

Mastery of English phrasal verbs is regarded as a stumbling block for English language learners, even at advanced levels. Possible sources of difficulty can be a lack of clear meaning and the random nature of particles. The lack of an organized approach to present phrasal verbs to the learners might be a factor that could exacerbate the situation of learning them. This study takes this issue as its point of departure. It investigates whether employing radial categories, conceptual categories with one prototypical concept and some peripheral members that are organized around it, is influential in the learning and long-term retention of these verbs. Moreover, the effect of employing radial categories to teach PVs on learners' cognitive load is investigated. For this purpose, 60 intermediate high school students in 10th and 11th grade were assigned to two groups, one experimental and one control group, each containing 30 students. The study results indicated that the experimental group learners who were taught phrasal verbs using radial categories outperformed control group learners who were taught using a traditional approach. This result suggests that radial categories may help facilitate learning phrasal verbs.

Aim: The aim of this research was to investigate the effect of cognitive load on reaction to the other's trust, with the moderating role of personality traits. Methods: Using available sampling method 85 at Persian Gulf University were selected and were asked to complete the HEXACO personality inventory. Then, using random assignment method, they were divided into four groups (four levels of cognitive load from no cognitive load to high cognitive load. Finally, participants were asked to complete a scenario that examined reaction to other's trust, under a variety of degrees of cognitive loads, mentioned above. The data were analyzed using hierarchical regression analysis (utilizing Baron and Keaney's method for assessing moderating effect).   Results: The results indicated that cognitive load causes a decrease in reaction to other's trust (R=0.683) and that each personality trait could moderate the effect of cognitive load on reaction to other’s trust. Conclusion: Considering the ever-increasing cognitive load caused by the explosion of information in the modern age, it is necessary to identify and strengthen the personality traits underlying trusting interpersonal relationships

Rooted in the Cognitive Load (CL) and Dual Coding theories, this sequential explanatory study examined the CL levels experienced by 36 available Iranian pre-intermediate English as a Foreign Language (EFL) learners in auditory and visual Phonemic Awareness Tasks (PATs). The PATs focused on 'th' sound variations that were specifically challenging for Persian speakers of English. Participants were divided into two equal groups. The first group underwent auditory and visual PATs (i.e., picture sorting and word discrimination). The second group faced auditory PATs only (i.e., rhyme recognition and sound isolation) structured around voiced and voiceless ‘th’ sounds. In the qualitative phase, 8 participants were randomly interviewed to discover the potential reasons behind various levels of CL measured in certain PATs. A Virtual Reality (VR) cognitive pupillometry analysis was performed for two groups in an immersive VR environment using VR Head-Mounted Displays (VR-HMDs) and Tobii Nexus software, followed by thematic analysis. GazeMetrics strategies were employed to validate and ensure the reliability of the data collection process. The quantitative results demonstrated (a) no critical differences regarding the CL experienced by the participants in each group concerning voiced vs. voiceless’ th’ PATs and (b) higher levels of CL (increased pupil diameter, decreased blink rates, and increased gaze pattern or fixation duration) among participants in the auditory PATs group compared to the ones in the auditory and visual PATs group. Besides, qualitative findings identified the following factors as the most probable causes of the observed differences in CL levels among participants: (a) segmental differences, (b) phonological transfer, (c) phonological fossilization, (d) working memory constraints, (e) cognitive flexibility, and (f) task delivery methods. This study contributes to cognitive phonology, phonological processing, perceptual-motor language functions, and English material development.

Despite being a popular topic in language testing, cognitive load has not received enough attention in vocabulary test items. The purpose of the current study was to scrutinize the cognitive load and vocabulary test items’ differences, examinees’ reaction times, and perceived difficulty. To this end, 150 students were selected using cluster/convenience-sampling, and took the Cambridge Placement Test (CPT) and Vocabulary Size Test (VST; Nation & Beglar, 2007). After uploading the vocabulary-size test’s items in PsychoPy software, there was a behavioral stage to measure students’ reaction times and correct responses. Out of these 150 high school students, a total of 60 (20 from each proficiency level of elementary/intermediate/advanced groups) were selected. In this quantitative study, all 60 students were interviewed to determine their perceived difficulty of the international VST items and their item’s difficulty-index. The data were analyzed quantitatively via simple regression and qualitatively through the examination of the students’ perceived difficulty. The results and interview findings revealed a significant connection between cognitive load/reaction time, difficulty estimate, and perceived difficulty at intermediate level. In contrast, at elementary and advanced levels, these variables could not predict the cognitive load. The findings can help to test, course, and syllabus designers by educating them on the significance of cognitive load theory so that they can base their exam designs on its premises and alleviate students' increased cognitive-workload.
