Comprehension difficulty

This study was designed to highlight the potential effects of different types of Explicit Syntactic Markers (ESMs) on the sentence comprehension of EFL learners of different age-range and proficiency levels. Consequently, two hundred and forty beginners, intermediate, and advanced Iranian EFL learners were selectedfrom an initial pool of six hundred and sixty learners. They were selected based on their McMillan Placement Test (MPT) performance. Subsequently, they were categorized into two age groups teenagers and adults. An online software application (Com-Chron) was utilized to provide learners with a set of ESM and non-ESM English sentences on the screen to measure the accurate comprehension and the elapsed time needed for the perception of the presented sentences. Data analyses revealed that participants had a significantly superior performance for comprehending the ESM items (though they were longer sentences than non-ESM items). Furthermore, it was revealed that proficiency level, unlike age, caused a statistically significant difference in comprehending the ESM sentences. It was also concluded that different types of explicit syntactic markers imposed different degrees of comprehension difficulty both in terms of accuracy and the needed time for the participants’ comprehension; sentences with punctuation marks and conjunctions were the easiest for the participants, while those including determiners and link breaks were the most challenging. Results also indicated that all the ESMs (except for the link breaks) can significantly account for English sentence comprehension and can be assumed as comprehension predictors to various degrees .

Much of the research on the comprehension of passive sentences has targeted healthy adults, L1 acquirers and people with aphasia. However, a topic that lacks evidence is the comprehension challenges of EFL learners facing different passive structure types. Consequently, this study investigated the comprehension difficulty of different passive structures by 186 intermediate EFL learners. The participants’ task was to read a sentence and choose a corresponding answer in a multiple-choice format via a software application designed for this study. The answers were analyzed in terms of the comprehension accuracy and the reaction time. Compared with the passive sentences, the participants needed less time comprehending active sentences and had a higher success rate. The results suggested that different passive verb types (i.e., regular/irregular, action/state, double-object/single-object, negative/affirmative, and question/statement) imposed different degrees of comprehension challenge to EFL learners; passives with regular verbs (PR) were the least challenging and passives with double-object verbs (PDO) were the most demanding structures. It was also revealed that the participants’ comprehension of different passive structures was significantly different based on their reaction times. The study’s findings may be of insight for EFL instructors and material developers to possibly invest more time for the more challenging passive structures.
