The effects of different learning conditions on the development of collocational knowledge in a second language

<p>Previous research has shown that incidental exposure to second-language collocations in reading texts can produce gains in declarative collocational knowledge. However, there is little evidence that incidental exposure leads to the acquisition of procedural collocational knowledge. One key study that investigated these two areas was Sonbul and Schmitt (2013). They found that advanced non-native speakers gained substantial declarative knowledge of low-frequency technical collocations after three exposures in two incidental reading conditions in one treatment session; typographic enhancement of the collocations produced more correct answers than no enhancement. However, the researchers found no evidence of procedural collocational knowledge in a primed lexical decision task. Experiment 1 in this thesis was a conceptual replication and extension of Sonbul and Schmitt (2013). In a counter-balanced learning and experimental condition, 62 advanced adult ESL speakers were exposed to nine occurrences of 15 low-frequency technical collocations in 500-word texts in three sessions on two consecutive days. (input flooding). Three incidental learning treatments were implemented: reading-only (typographically unenhanced), bolding-only and bolding-plus-glossing. Collocational knowledge was assessed in two tests of declarative knowledge: a cued-recall (gapfill) test and a form-recognition (multiple-choice) test. Procedural collocational knowledge was operationalised as a priming effect in a primed lexical decision task. The results of the immediate cued-recall and form-recognition post-tests corroborate Sonbul and Schmitt’s findings: multiple encounters with the collocations produced substantial declarative collocational knowledge, and more declarative knowledge was produced through exposure to typographically-enhanced collocations (with and without glosses) than to typographically-unenhanced collocations. Procedural knowledge was found, but, unexpectedly, only in the reading-only treatment. Experiment 2 focused on non-technical lexical (verb + noun) collocations and grammatical (preposition + noun) collocations. Two incidental learning conditions were used: bolding and no-bolding. Seventy-eight intermediate-to-upper-intermediate-level adult native speakers of Chinese were exposed to six occurrences of each of 48 non-technical English collocations as they read twelve 170-word treatment texts on two consecutive days. The immediate post-test session comprised a gapfill (cued-recall) test, for measuring declarative knowledge, and a self-paced reading task, for measuring procedural knowledge. The results show an increase in declarative knowledge in both learning conditions. Bolding produced more declarative knowledge of preposition + noun collocations than no bolding; however, bolding was no more effective than no bolding for verb + noun collocations. In the self-paced reading task, the absence of bolding of verb + noun collocations led to a tendency towards the development of procedural knowledge, but this was not the case for the typographically enhanced verb + noun collocations. For preposition + noun collocations (both unbolded and bolded) no evidence of procedural knowledge was found. The findings of both experiments indicate that input flooding of collocations in incidental learning conditions can produce declarative collocational knowledge, and that typographic enhancement may lead to more declarative knowledge than lack of typographic enhancement. Repeated exposure to typographically-unenhanced collocations in reading contexts may produce procedural knowledge of collocations more quickly than exposure to typographically-enhanced collocations. These findings indicate that declarative and procedural knowledge of MWUs are dissociated in the sense that they follow different developmental paths. In a teaching context, I predict that the knowledge of collocations may be acquired incidentally through the use of texts such as graded readers which contain multiple instances of collocations.</p>

Effect of Word Exposure Frequency on Chinese Advanced EFL Learners’ Incidental Vocabulary Acquisition

The present study explores the effect of word exposure frequency on Chinese advanced EFL learners’ incidental acquisition of three aspects of word knowledge (i.e., word form, word class and word meaning). The participants were 20 Chinese English postgraduates who read two chapters of an original English novel and took four vocabulary tests. The target words were 20 pseudo-words created to replace the words that naturally occurred from one to twenty times in the text. The results show that word exposure frequency has a significant effect on IVA through reading, exerting the strongest effect on word form recognition and the weakest on word meaning recall. The study also finds that seven is the threshold value for significant word gain growth and that local word frequency also influences learners’ IVA.

The effects of emotional context and exposure frequency on L2 contextual word learning

Objectives: An experiment was conducted to explore how emotional valence of contexts and exposure frequency of novel words affect second language (L2) contextual word learning. Methodology: Chinese native speakers who learned English in a formal classroom setting were asked to read English paragraphs with different emotional valence (positive, negative or neutral) across five different days. These paragraphs were embedded with pseudowords. During this learning process, form recognition test and meaning recall test were carried out for these pseudowords. Data and analysis: Data were analyzed using mixed-model ANOVA. Accuracy for each task was compared among the three kinds of emotional contexts. Findings/Conclusions: In the form recognition test, the accuracy in the negative context was higher than in the positive and neutral contexts, and the pseudowords were acquired much earlier. In the meaning recall test, the accuracy in the positive and negative contexts was higher than that in the neutral context. Accuracy increased gradually with the increase of exposure frequency of the pseudowords. More importantly, we found that less exposure times were needed for emotional context relative to neutral context in contextual word learning. Originality: This may be the first study to explore the influence of emotional valence and exposure frequency on L2 contextual word learning. Significance/Implications: This study underlined the importance of emotional information in L2 contextual word learning and contributed to the understanding of how emotional information and exposure frequency functions in this learning process.

EEG theta responses induced by emoji semantic violations

This study investigated emoji semantic processing by measuring changes in event-related electroencephalogram (EEG) power. The last segment of experimental sentences was designed as either words or emojis consistent or inconsistent with the sentential context. The results showed that incongruent emojis led to a conspicuous increase of theta power (4–7 Hz), while incongruent words induced a decrease. Furthermore, the theta power increase was observed at midfrontal, occipital and bilateral temporal lobes with emojis. This suggests a higher working memory load for monitoring errors, difficulty of form recognition and concept retrieval in emoji semantic processing. It implies different neuro-cognitive processes involved in the semantic processing of emojis and words.

Visuo-motor integration, vision perception and attention in mTBI patients. Preliminary findings

Patients with mild traumatic brain injuries (mTBI) often report difficulties in motor coordination and visuo-spatial attention. However, the consequences of mTBI on fine motor and visuo-motor coordination are still not well understood. We aimed to evaluate whether mTBI had a concomitant effect on fine motor ability and visuo-motor integration and whether this is related to visual perception and visuo-spatial attention impairments, including patients at different symptoms stage. Eleven mTBI patients (mean age 22.8 years) and ten healthy controls participated in the study. Visuo-motor integration of fine motor abilities and form recognition were measured with the Beery-Buktenica Developmental Test of Visual-Motor Integration test, motion perception was evaluated with motion coherence test, critical flicker fusion was measured with Pocket CFF tester. Visuo-spatial was assessed with the Ruff 2 & 7 Selection Attention Test. mTBI patients showed reduced visuo-motor integration, form recognition, and motor deficits as well as visuo-spatial attention impairment, while motion perception and critical flicker fusion were not impaired. These preliminary findings suggest that the temporary brain insults deriving from mTBI compromise fine motor skills, visuomotor integration, form recognition, and visuo-spatial attention. The impairment in visuo-motor coordination was associated with speed in visuo-attention and correlated with symptoms severity while motor ability was correlated with time since concussion. Given the strong correlation between visuomotor coordination and symptom severity, further investigation with a larger sample seems warranted. Since there appeared to be differences in motor skills with respect to symptom stage, further research is needed to investigate symptom profiles associated with visuomotor coordination and fine motor deficits in mTBI patients.

Industry 4.0 revolve the way of thinking in manufacturing factory business. Speed and accuracy become the main focus to survive and To growth. This study aims to build a blue print of an system that will increase both speed and accuracy in form input. This research will use several computer vision technologies like CNN that will used to do form classification and image segmentation, there is also OCR that will take specific information from a document that have been classified with CNN and then transform it into a JSON format which have more generic format and can be used in most common platform.

Exploring the learning burden and decay of foreign language vocabulary knowledge

Research has shown that several intralexical factors affect the learning burden of foreign language vocabulary (e.g., Laufer, 1997) and that some accrued lexical knowledge is forgotten. It is often assumed that the lexical items most difficult to acquire are those easiest to forget. However, few studies have provided empirical evidence to support this claim. This study examined the effect of two intralexical factors, part of speech and word length, on the learning burden and decay of intentionally learned foreign language lexical knowledge, as well as the role that learning burden played in the decay process. Forty-eight learners of English studied words of various parts of speech and lengths using flashcard software. Knowledge (form recall and recognition) of target items was assessed immediately after learning and four weeks later. Results of mixed-effects models showed that part of speech and word length have differential impacts on learning burden and decay and that increased burden mitigated loss of form recognition knowledge.
