Differential Mnemonic Contributions of Cortical Representations during Encoding and Retrieval.

Several recent fMRI studies of episodic and working memory representations converge on the finding that visual information is most strongly represented in occipito-temporal cortex during the encoding phase but in parietal regions during the retrieval phase. It has been suggested that this location shift reflects a change in the content of representations, from predominantly visual during encoding to primarily semantic during retrieval. Yet, direct evidence on the nature of encoding and retrieval representations is lacking. It is also unclear how the representations mediating the encoding-retrieval shift contribute to memory performance. To investigate these two issues, in the current fMRI study, participants encoded pictures (e.g., picture of a cardinal) and later performed a word recognition test (e.g., word "cardinal"). Representational similarity analyses examined how visual (e.g., red color) and semantic representations (e.g., what cardinals eat) support successful encoding and retrieval. These analyses revealed two novel findings. First, successful memory was associated with representational changes in cortical location (from occipito-temporal at encoding to parietal at retrieval) but not with changes in representational content (visual vs. semantic). Thus, the representational encoding-retrieval shift cannot be easily attributed to a change in the nature of representations. Second, in parietal regions, stronger representations predicted encoding failure but retrieval success. This encoding-retrieval "flip" in representations mimics the one previously reported in univariate activation studies. In summary, by answering important questions regarding the content and contributions to the performance of the representations mediating the encoding-retrieval shift, our findings clarify the neural mechanisms of this intriguing phenomenon.

Sensitive periods in language development: Do children outperform adults on auditory word-form segmentation?

Children are more successful language learners than adults, yet the nature and cause of this phenomenon are still not well understood. Auditory statistical learning from speech has been a prominent focus of research in the field of language development because it is regarded as a fundamental learning mechanism underlying word segmentation in early language acquisition. However, a handful of studies that investigated developmental trajectories for auditory statistical learning found no clear child advantages. The degree to which the learning task measures explicit rather than implicit mechanisms might obscure a potential advantage for younger learners, as suggested by recent findings. In the present study, we compared children aged 7–12 years and young adults on an adapted version of the task that disentangles explicit and implicit contributions to learning. They were exposed to a continuous stream of speech sounds comprising four repeating trisyllabic pseudowords. Learning of the hidden words was tested (a) online through a target-detection task and (b) offline via a forced-choice word recognition test that included a memory judgement procedure. Both measures revealed comparable learning abilities. However, children's performance on the recognition task showed evidence for both explicit and implicit word knowledge while adults appeared primarily sensitive to explicit memory. Since implicit memory is more stable in time than explicit memory, we suggest that future work should focus more on developmental differences in the nature of the memory that is formed, rather than the strength of learning, when trying to understand child advantages in language acquisition.

아동양육시설 초등학생들의 기초문해력 실태 조사

The purpose of this study was to examine the level of basic literacy skills among elementary school students in residential child care institution based on their reading development. A total of 118 students participated in the reading screening test. According to the results of the screening test, students with severe reading difficulties were classified as ‘at risk’, students with reading difficulties were classified as ‘some risk’, and students with average and above average reading levels were classified as ‘typical’. The ‘at risk’ students were administered the Korean language acquisition and word recognition tests, while students in the ‘some risk’, and ‘typical’, were administered the reading fluency and comprehension tests. The main research findings are as follows. First, elementary school students in residential child care institution generally showed low levels of basic literacy skills. Second, almost students in the ‘at risk’ group were found to have difficulty in word recognition. Third, students in the ‘some risk’ and ‘typical’ groups were found to have greater difficulty in reading comprehension than reading fluency. Based on these research results, implications for enhancing basic literacy skills of elementary school students in residential child care institution were proposed.

Evaluating Hearing Status and Word Recognition Ability in the Hmong Population Using Four Validated Monosyllabic White Hmong Dialect Word Recognition Tests.

The study's aims were (a) to evaluate hearing status and (b) word recognition ability of Hmong speakers using four validated monosyllabic word recognition tests in the White Hmong dialect and (c) to assess the relationship between the participant's language and the average word recognition percent correct scores, adjusting for age, gender, and degree of hearing loss. Participants listened to two randomly assigned validated Hmong word lists (male/female talker) for each ear. Pure-tone air- and bone-conduction thresholds as well as word recognition ability were measured. Descriptive statistics were calculated to analyze the percent correct of word lists and classify hearing status. A nonparametric regression analysis was used to assess the relationship between the participant's language and the average word recognition percent correct scores, adjusting for age, gender, and degree of hearing loss. Forty-eight Hmong (25 females, 23 males; Mage = 44.4) participated in this study. Thirty-three participants had hearing loss in at least one ear, and 15 had hearing within normal limits bilaterally. Participants with normal, mild, or steeply sloping hearing loss reached an average word recognition score of > 94% on Hmong lists by both male and female talkers. Participants with moderate-to-severe hearing loss scored 68% on average for the male talker Hmong lists and 60% on average for the female talker Hmong lists. Gender was significantly positively associated with average word recognition percent correct on the female word lists (b = -0.224, p = .047) but not statistically significant for the male word lists (b = 7.579, p = .141). Findings provide support for the use of the four Hmong word lists in clinical settings.

Investigating the EFL Learners’ Visual Word Recognition: Words’ Frequency, Length, Regularity and Superiority Effects in Comparison

This study scrutinized the effects of words’ superiority, regularity, frequency and length on the intermediate and advanced EFL learner's visual word recognition. Moreover, it attempted to check whether each of these parameters could be statistically a significant predictor on recognition tasks. Accordingly, 118 intermediate and 127 advanced adult EFL learners were selected randomly from English Language Institutes based on their performance on the McMillan Placement Test (MPT). The needed data was collected through a developed Visual Word Recognition Test (WORT) and the Peabody Picture Vocabulary Test (PPVT). The findings indicated that all the mentioned factors significantly affected both the intermediate and the advanced EFL learners’ overall word recognition by varying degrees (words’ frequency, length, superiority and regularity, respectively), however, the advanced learners’ recognition was generally faster on both recognition tests. Moreover, words' regularity was found to play a more effective role for the intermediates than the advanced learners on recognition tasks. Furthermore, words’ frequency, regularity and length were found to be proper predictors on comprehension tasks.

Phonology, homophony, and eyes-closed rest in Mandarin novel word learning: An eye-tracking study in adult native and non-native speakers

AbstractThis study used the visual world paradigm to investigate novel word learning in adults from different language backgrounds and the effects of phonology, homophony, and rest on the outcome. We created Mandarin novel words varied by types of phonological contrasts and homophone status. During the experiment, native (n = 34) and non-native speakers (English; n = 30) learned pairs of novel words and were tested twice with a 15-minute break in between, which was spent either resting or gaming. In the post-break test of novel word recognition, an interaction appeared between language backgrounds, phonology, and homophony: non-native speakers performed less accurately than native speakers only on non-homophones learned in pairs with tone contrasts. Eye movement data indicated that non-native speakers’ processing of tones may be more effortful than their processing of segments while learning homophones, as demonstrated by the time course. Interestingly, no significant effects of rest were observed across language groups; yet after gaming, native speakers achieved higher accuracy than non-native speakers. Overall, this study suggests that Mandarin novel word learning can be affected by participants’ language backgrounds and phonological and homophonous features of words. However, the role of short periods of rest in novel word learning requires further investigation.

The effects of EFL wordlist and proficiency on vocabulary knowledge.

The Gaokao Word List (GWL) in China serves as a guideline for learning L2 vocabulary, but there are few studies verifying its effect on university EFL learners' vocabulary knowledge. This study investigated the effects of the GWL and EFL proficiency on 66 Chinese university EFL learners' vocabulary knowledge by administering word recognition tests. The results showed that: (1) the GWL had significant effects on participants' receptive vocabulary knowledge; (2) EFL proficiency had significant effects on participants' word recognition, without interaction with the GWL. These findings were discussed through the lens of frequency of exposure, accounting for the overwhelming GWL effect on learners' vocabulary knowledge. We suggest EFL proficiency be taken into consideration when the GWL is revised in the future, to smoothen the transition in vocabulary learning from high school to university, and improve vocabulary learning efficiency.

The Effectiveness of Instructional Design Based on Dual Learning Strategies on Word Recognition

This study aims at showing the effectiveness of dual learning strategies on language skills of EFL students. The experimental design of the study involved three groups which are chosen randomly where two are experimental groups and the other is control one. The sample of the study are 1st intermediate class students. The experimental groups are taught by different dual learning strategies , whereas the control group is taught by traditional method of teaching. It is hypothesized that there are significant differences between the two experimental and control groups. The instrument of the study is students’ performance in word recognition test. After collecting data and analyzing them , conclusions are drawn according to the finding of the statistics of the study.

A Greek Pediatric Word Recognition Test by Picture Identification.

(1) Background: The study aimed to construct a clinically valuable closet-set WRS test with a picture identification task for young Greek-speaking children. (2) Methods: The test material was meticulously designed based on specific criteria. To determine which parts of speech are used more frequently by preschool children, a spontaneous speech sample (250 words per child) was acquired from three hundred children aged 3 to 6 years (M = 4.56, SD = 0.90). The study involved the development and application of two phonemically balanced 50-word lists suitable for young children, as well as the creation of picture representations for each response set. All testing was accomplished in an audiometric booth that exceeded the audiometric rooms' ambient noise level standards. The speech signal was routed from a laptop computer to a GSI 61 audiometer, and all test items were delivered from the audiometer to the subject. (3) Results: The results indicated that materials for a WRS test for young children are developed with high face validity and are applicable for children as young as three years old. The test satisfies the essential components needed for a WRS test. It consists of two phonemically balanced 50-word lists with low-redundancy bisyllabic words, with each list containing 227 phonemes. (5) Conclusions: This novel closed-set WRS test presents a valuable tool for assessing speech perception skills in young Greek-speaking children. The test results have various applications, including diagnosis, research, and (re)habilitation.

Social robots as effective language tutors for children: empirical evidence from neuroscience

The aim of the current study was to investigate children's brain responses to robot-assisted language learning. EEG brain signals were collected from 41 Japanese children who learned French vocabularies in two groups; half of the children learned new words from a social robot that narrated a story in French using animations on a computer screen (Robot group) and the other half watched the same animated story on the screen but only with a voiceover narration and without the robot (Display group). To examine brain activation during the learning phase, we extracted EEG functional connectivity (FC) which is defined as the rhythmic synchronization of signals recorded from different brain areas. The results indicated significantly higher global synchronization of brain signals in the theta frequency band in the Robot group during the learning phase. Closer inspection of intra-hemispheric and inter-hemispheric connections revealed that children who learned a new language from the robot experienced a stronger theta-band EEG synchronization in inter-hemispheric connections, which has been previously associated with success in second language learning in the neuroscientific literature. Additionally, using a multiple linear regression analysis, it was found that theta-band FC and group assignment were significant predictors of children's language learning with the Robot group scoring higher in the post-interaction word recognition test. These findings provide novel neuroscientific evidence for the effectiveness of social robots as second language tutors for children.

Threshold Estimation and Speech Perception Under Hearing Loss Simulation: Examination of the Immersive Hearing Loss and Prosthesis Simulator

Purpose: Hearing loss simulation (HLS) has been recommended for clinical teaching and counseling of patients and their families, so that they can experience hearing impairment. However, few validated procedures for simulating hearing loss are available to instructors and practicing clinicians. The aim of this study was to assess the accuracy of the Immersive Hearing Loss and Prosthesis Simulator (I-HeLPS) on reducing hearing sensitivity and word recognition to determine its adequacy for educational and clinical use. Method: Thirty-seven young adults with normal hearing completed hearing threshold and word recognition testing under normal and simulated hearing losses. The accuracy of the nominal hearing threshold settings within the I-HeLPS software was assessed with behavioral detection of frequency-modulated pure tones presented in a calibrated sound field, while listeners wore I-HeLPS headphones. The impact of the HLSs on speech perception was measured using the California Consonant Test. Hearing thresholds, word identification accuracy, and sound confusions were compared across listening conditions. Results: Hearing thresholds increased systematically with worse simulated hearing loss. Performance on the California Consonant Test worsened, and the number of phoneme confusions increased with simulated hearing loss severity. Most of the confusions were place confusions with near neighbors and manner confusions increased as a function of increasing severity of simulated hearing loss. Conclusions: The I-HeLPS accurately elevated hearing thresholds with increasing HLS severity and impacted word recognition in a manner consistent with sensorineural hearing loss. The simulations were considered reasonable for educational and clinical purposes. Supplemental Material: https://doi.org/10.23641/asha.24520966

Does the Sensory Experience of Words Boost Recollection in Aging?

ABSTRACT Objectives We examine age-related differences in recollection and test the impact of words with high vs low sensory experience ratings (SER) in older and younger adults. We expected that the recollection of words with high SER would be similar in older and young adults, as they depend on knowledge, unlike recollection of words with a low SER, which would depend on executive functions. Methods We manipulated the sensory experience of words (high vs. low) in encoding in young and older adults. The participants then took a word-recognition test using the Remember/Know paradigm (Gardiner, 1988). We also evaluated executive functions using several measures. Results Results show that the age-related difference in recollective experience was eliminated under the high SER encoding condition. Moreover, Remember (R) responses in the low SER condition seem to be related to executive functioning, unlike R responses in the high SER condition and Know (K) responses in both low and high SER conditions. Discussion Our study shows that the memory benefit of high-SER words is greater for older than younger adults. The study also supports the observation that older adults can compensate for their deficits by using sensory experience to consciously recollect information.

The effects of active and relaxing music on the short-term memory, attention and metabolic parameters of type 2 diabetes patients (T2DM)

Objective. Metabolic parameters and cognition are known to be impaired in diabetes, while music seems to have an impact on both. We aimed to study the effects of active and relaxing music on the short-term memory, attention and metabolic parameters of type 2 diabetes patients (T2DM).
 Methods. A two-day interventional, within-subject study was carried on 89 T2DM patients treated only with metformin and 67 age- and sex-matched control. The Pieron Toulouse test and Word Recognition Test were used to evaluate attention and short-term memory. The music listened to was the Allegro, respectively the Andante parts of 2 Mozart Sonatas. Cognitive tests, blood pressure and blood
 glucose measurements were performed before and after each 20 minutes of music intervention.
 Results. Baseline attention performance was better in the control group compared to T2DM (p<0.000). Performance improved significantly in both groups under both types of music, however the last to the first measurement difference was higher in the control group (p=0.04). Female T2DM participants had better improvement under active music (p<0.01). Short-term memory improved during active music, but this was significant only in the control group (p=0.041). Both types of music were associated with significantly lower systolic blood pressure (p=0.00), while relaxing music significantly reduced blood glucose levels (p=0.00).
 Conclusion. Our study highlighted the beneficial effect of music on metabolic and cognitive parameters, however, its impact depends on the type of music listened. Furthermore, cognitive scores of T2DM, especially in men, were less influenced by music than those of the control group.

Measure of Auditory Working Memory Span Using Monosyllabic Word Recognition Test in Young Adults With Normal Hearing: A Preliminary Study.

Measuring working memory at hearing clinics is important. This study attempted to develop a test protocol that measures auditory working memory using a standardized monosyllabic word list in Korean Speech Audiometry (KSA). We included 25 young adults with normal hearing in this study. Participants conducted word recognition and word span tests concurrently using the KSA monosyllabic word lists. We designed four test conditions according to the presence or absence of background noise and word recall order: quiet-forward (QF), quiet-backward (QB), noise-forward, (NF), and noise-backward (NB). We implemented digit span tests in the Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV) to determine the validity of the working memory outcomes. Word recognition scores of QF and QB were significantly higher than those of NF and NB. The percentages of correctly recalled words and word recall span scores were highest in QF and lowest in NB. Overall, the Pearson correlation and multiple regression statistics showed that our word span test outcomes for QB and NF were highly associated with digit span scores on the K-WAIS-IV. Our proposed test protocol showed the possibility of measuring auditory working memory and monosyllabic word recognition simultaneously by validating the results with K-WAIS-IV outcomes.

Crosslinguistic differences in initial word recognition

Abstract The present article addresses the extent to which learners’ mental representations, in particular the phonological and lexical representations of learners’ background languages, influence their ability to perceive and extract linguistic units from a novel speech stream. In the study, native speakers of French were exposed to an unfamiliar language, either Polish or Modern Standard Arabic. A word recognition test taken at first exposure revealed important differences in how French speakers/listeners extract words from the Polish or Arabic speech stream, suggesting that source language representations work differently depending on the specificities of the target language. In addition to providing insights into the effects of source and target language properties on speech perception, these results contribute to on-going discussions about what constitutes crosslinguistic influence and conceptual transfer in second language acquisition research.

How Can We Compare Cochlear Implant Systems across Manufacturers? A Scoping Review of Recent Literature.

Electric stimulation via a cochlear implant (CI) enables people with severe-to-profound sensorineural hearing loss to regain speech understanding and music appreciation and, thus, allow them to actively engage in social life. Three main manufacturers (CochlearTM, MED-ELTM, and Advanced BionicsTM "AB") have been offering CI systems, thus challenging CI recipients and otolaryngologists with a difficult decision as currently no comprehensive overview or meta-analysis on performance outcomes following CI implantation is available. The main goals of this scoping review were to (1) map the literature on speech and music performance outcomes and to (2) find whether studies have performed outcome comparisons between devices of different manufacturers. To this end, a literature search was conducted to find studies that address speech and music outcomes in CI recipients. From a total of 1592 papers, 188 paper abstracts were analyzed and 147 articles were found suitable for an examination of full text. From these, 42 studies were included for synthesis. A total of 16 studies used the consonant-nucleus-consonant (CNC) word recognition test in quiet at 60 db SPL. We found that aside from technical comparisons, very few publications compared speech outcomes across manufacturers of CI systems. However, evidence suggests that these data are available in large CI centers in Germany and the US. Future studies should therefore leverage large data cohorts to perform such comparisons, which could provide critical evaluation criteria and assist both CI recipients and otolaryngologists to make informed performance-based decisions.

Cognitive enrichment and education quality moderate cognitive dysfunction in black and white adults with multiple sclerosis.

To examine the extent to which three sociobehavioral proxies of cognitive reserve-years of education, education quality, and cognitive enrichment-differ in their prediction of cognitive performance among Black and White people with MS (PwMS). 82 PwMS (Black n=41, White n=41) underwent a neurological examination and a neuropsychological evaluation that included tests of word recognition (Wechsler Test of Adult Reading) as well as measures of verbal memory, visuospatial memory, and processing speed (the Brief International Cognitive Assessment for MS; BICAMS). Participants rated their lifetime engagement in various cognitively-enriching activities (Cognitive Reserve Scale). For the full sample, education quality and cognitive enrichment were more strongly associated with cognitive performance than were years of education. Cognitive enrichment was not associated with cognitive performance among participants with high education quality. In contrast, among participants with low education quality, cognitive enrichment was strongly associated with cognitive performance, suggesting that high engagement in cognitively-enriching activities provided similar protection to high education quality. Furthermore, among Black participants, cognitive enrichment and educational quality moderated the relationship between disability level and cognitive performance. In contrast, among White participants, cognitive enrichment did not provide additional protection beyond the buffering effect of education quality. PwMS can successfully build reserve through multiple routes, including formal education or informal cognitive enrichment. Treatment for MS should incorporate cognitively-enriching activities to build resilience against cognitive decline, particularly for members of marginalized racial/ethnic groups, who are at greatest risk for poor health outcomes, and for whom years of education may not best reflect education quality.

Efficiency of EEG-Guided Adaptive Neurostimulation Increases with the Optimization of the Parameters of Preliminary Resonant Scanning

The development and improvement of closed-loop methods for non-invasive brain stimulation is an actual and rapidly developing area of neuroscience. An innovative version of this approach, in which a person is presented with audiovisual therapeutic stimulation, automatically modulated by the rhythmic components of his electroencephalogram (EEG), is EEG-guided adaptive neurostimulation. The present study aims to experimentally test the assumption that the effectiveness of EEG-guided adaptive neurostimulation can be increased by optimizing the parameters of preliminary resonance scanning, which consists of LED photostimulation with stepwise increasing frequency in the range of θ-, α-, and β EEG-rhythms. In order to test this assumption, we compared the effects of two types of resonance scanning, which differ in the step length of the gradually increasing frequency of LED photostimulation. The experiments involved two equal groups of university students in a state of exam stress. Before EEG-guided adaptive stimulation, one of the groups underwent resonance scanning with a short (3 s), and the other with a long (6 s) step of a gradual increase in the frequency of photostimulation. Changes in the EEG and psychophysiological parameters were analyzed under the influence of combined (resonance scanning plus EEG-guided adaptive neurostimulation) interventions relative to the initial level. It was found that only with a short (3 s) step of increasing the frequency of photostimulation, significant increases in the power of EEG-rhythms are observed, accompanied by significant changes in subjective indicators – a decrease in the number of errors in the word recognition test, a decrease in the level of emotional maladaptation, and an increase in well-being scores. The revealed positive effects are already observed after single therapeutic procedures due to the optimal conditions for the involvement of the resonant and integration mechanisms of the brain and the mechanisms of neuroplasticity in the processes of normalization of body functions. The developed combined approach to neurostimulation after additional experimental studies can be used in a wide range of rehabilitation procedures.

가상현실(Virtual Reality) 기반 노인난청의 청능훈련프로그램 사례연구

Objectives In this study, a virtual reality (VR) auditory training program, which was created to provide experiences similar to reality through computer software and hardware with the development of technology according to the 4th industry, was conducted with auditory training for 6 weeks (1 session per week) for two elderly people with hearing loss, and the change in word recognition and sentence comprehension ability was investigated.
 Methods For this purpose, 6 sessions of auditory training programs using virtual reality contents (eating out, go on a trip, making phone calls, watching radio, talking in public transportation (subway), using public institutions (hospital)) were provided for 6 weeks (1 session per week). The effects of the auditory training program, word recognition and sentence comprehension tests were conducted before-and-after implementing the program.
 Results The results of the virtual reality-based auditory training program for two elderly people with hearing loss are as follows: First, presbycusis A and B showed improved scores in word recognition as auditory training sessions were repeated, and training was effective even under difficult hearing conditions with noise. Second, when the pre-test and post-test values were compared, there was no significant difference in the change in word and sentence recognition of the two presbycusis.
 Conclusions This study focused on improving listening ability by conducting a daily life-oriented virtual reality auditory training program for the elderly with hearing loss. In addition, it is meaningful in that it provides motivation for hearing ability through auditory training to the elderly who have worn hearing aids for a long time and the necessity of systematic auditory training.

IRANIAN UNIVERSITY LEARNERS’ ENGLISH VOCABULARY LEARNING USING SYNONYM AND L1 TRANSLATION

Vocabulary is part and parcel of learning of a second or a foreign language. This study examined the effect of vocabulary learning through translation of English words (Persian equivalents) and the use of English synonym on the retention and retrieval of vocabularies. Static-group comparison design was utilized to scrutinize sixty EFL learners split into two groups. The experimental group was instructed on the memorizing strategies and the control one left alone to memorize words presented in class in a week time span. The experimental group being taught on coding, interim device, and visual imagery strategies was assayed on spot by dint of written word recognition tests for their receptive knowledge of synonyms written on the board. The findings of the matching test tasks divulged that the learners’ recognitions of synonyms than the first language equivalents were significantly higher. The experimental group significantly scored higher in the recognition test of synonyms than that of translation equivalents. Results have practical implications and application for foreign language learning and teaching which are discussed.
