Race-ethnicity and the big-fish-little-pond effect in the United States

According to research on the big-fish-little-pond effect, students with a high rank in a low rank school have more favorable self-evaluations than students with a low rank in a high rank school. We examined whether this effect extends to a racial-ethnic context. Black and White adults in the United States completed a social perception test and were told that they had a high rank in a racial group that performed poorly or a low rank in a racial group that performed well. Black participants identified more strongly with their racial group than White participants. However, the big-fish-little-pond effect occurred and was similar in size across Black and White participants. These results suggest that the big-fish-little-pond effect generalizes to a racial-ethnic context and replicates across majority and minority group members.

Relation between electrical compound action potential measures and speech perception in cochlear implanted children: audiological and phonological outcomes

PurposeTo study ECAP measures (threshold and amplitude growth function 'AGF') in children CI users and find the relation between these ECAP measures and speech outcomes using audiological and phonological assessment.Subjects and methodTwenty-one children were unilaterally implanted with Medel CI, and all subjects were submitted to phonological assessment, basic audiological assessment, speech recognition tests (WRS and BKB-SIN) and Medel maestro software measures (IFT, AutoART and AGF measures "thresholds and slopes" across apical, middle and basal electrodes).ResultsThis study demonstrated no statistically significant difference between AGF thresholds at apical, middle and basal electrodes and a statistically significant difference between AGF slopes at apical and both middle and basal electrodes. There was no statistically significant correlation between the ECAP threshold and speech perception tests. In contrast, a positive statistically significant correlation was found between the AGF slope of the apical electrode and word recognition score, and a negative statistically significant correlation between AGF slopes at apical, middle and basal electrodes and SNR loss of BKB-SIN. High sensitivity and specificity of AGF slope at apical electrode were found to differentiate between good and poor performers as regards SNR loss of BKB-SIN and language test.ConclusionsThe AGF slope reflects neural survival better than the ECAP threshold. AGF slope at apical electrodes correlated with better CI performance in both phoniatric and audiological measures of speech perception and can be used as an objective tool to predict CI outcome.

An Animal Model of Neonatal Intensive Care Unit Exposure to Light and Sound in the Preterm Infant.

According to the World Health Organization, ∼15 million children are born prematurely each year. Many of these infants end up spending days to weeks in a neonatal intensive care unit (NICU). Infants who are born prematurely are often exposed to noise and light levels that affect their auditory and visual development. Children often have long-term impairments in cognition, visuospatial processing, hearing, and language. We have developed a rodent model of NICU exposure to light and sound using the Mongolian gerbil (Meriones unguiculatus), which has a low-frequency human-like audiogram and is altricial. To simulate preterm infancy, the eyes and ears were opened prematurely, and animals were exposed to the NICU-like sensory environment throughout the gerbil's cortical critical period of auditory development. After the animals matured into adults, auditory perceptual testing was carried out followed by auditory brainstem response recordings and then histology to assess the white matter morphology of various brain regions. Compared to normal hearing control animals, NICU sensory-exposed animals had significant impairments in learning at later stages of training, increased auditory thresholds reflecting hearing loss, and smaller cerebellar white matter volumes. These have all been reported in longitudinal studies of preterm infants. These preliminary results suggest that this animal model could provide researchers with an ethical way to explore the effects of the sensory environment in the NICU on the preterm infant's brain development.

Differences in social perception in people with schizophrenia and bipolar disorder

People with schizophrenia have difficulties recognizing other people's expressions, emotional states, and intentions; however, much less is known about their ability to perceive and understand social interactions. We used scenes depicting social situations to compare responses from 90 volunteers (healthy controls [HC], schizophrenia [SZ], and bipolar disorder [BD] outpatients from the Hospital del Salvador in Valparaíso, Chile) to the question: “What do you think is happening in the scene?” Independent blind raters assigned a score of 0 (absent), 1 (partial), or 2 (present) for each item based on whether the description identifies a) the context, b) the people, and c) the interaction depicted in the scenes. Regarding the context of the scenes, the SZ and BD groups scored significantly lower than the HC group, with no significant difference between the SZ and BD groups. Regarding the identification of the people and the interactions, the SZ group scored lower than the HC and BD groups, with no significant difference between the HC and BD groups. An ANCOVA was used to examine the relationship between diagnosis, cognitive performance, and the results of the social perception test. The diagnosis had an effect on context (p = .001) and people (p = .0001) but not on interactions (p = .08). Cognitive performance had a significant effect on interactions (p = .008) but not on context (p = .88) or people (p = .62). Our main result is that people with schizophrenia may have significant difficulties perceiving and understanding social encounters between other people.

Novel cochlear implant assessment tool: Comparative analysis of children and adults.

To analyse the results of children and adults with cochlear implants (CIs) in pure tone audiometry (PTA) and speech perception tests. Tests were performed in two ways: using loudspeakers in the sound booth (SB) and with direct audio input (DAI) employing the Cochlear Latin America BOX (CLABOX). Fifty individuals (33 adults and 17 children) participated in the study, including children aged between 8 and 13 years; of these, 15 users had bilateral CIs, 35 had unilateral CIs, and all had severe to profound bilateral sensorineural hearing loss. All participants were evaluated in the SB with loudspeakers and the CLABOX with DAI. The following evaluations were conducted: PTA, speech recognition tests with the hearing in noise test (HINT). The results for PTA and HINT conducted in SB and with CLABOX presented no significant difference between children and adults. The CLABOX tool presents a new possible method to evaluate PTA and speech recognition tests in adults and children, with results comparable to the conventional evaluation in the SB.

多様式失認が疑われた左視床出血の1例

We report a case of a 67-year-old man with left thalamic hemorrhage. He had right hemiplegia, aphasia, and higher brain dysfunction. The hemiplegia and aphasia improved with rehabilitation treatment；however, he was unable to perform activities of daily living. Visual and tactile agnosia was suspected using the visual perception test for agnosia 1 month after the hemorrhage. The patient was able to recognize common objects, such as chopsticks and a shaver, by labeling them with their names because he could read words. He was able to use these objects as a result. Multimodal agnosia with combined visual-tactile agnosia usually occurs as lesions in and around the left lateral occipital complex where the ventral stream of somatosensory information processing merges with that of visual information processing. Concurrently, the present case seems very unusual because multimodal agnosia was likely to have occurred as a lesion of the left thalamus. The compensatory strategy to put objects into words was effective in this case. We repeatedly assessed and analyzed his higher brain dysfunction in detail, which led to effective rehabilitation treatment. The present case highlights the importance of planning an appropriate treatment based on detailed evaluation and accurate diagnosis of the higher brain dysfunction in patients with neurological deficits.

Hazard perception test among young inexperienced drivers and risk analysis while driving through a T-junction

In this article, the hazard-based accident duration model and the reaction time due to various types of distractions are considered. This analysis is mainly considered T-junction or T-junctions like all other forms of road geometries which are more prone to accident. The model proposed is constructed by using a electronics devices along with driving simulator, to study the behavior of the yang inexperienced drivers as well as an experienced driver about their reaction by calling their phone from unknown numbers intentionally. The results show that drivers distracted by mobile phones uses the hard breaking due to least available time to respond after identification of an event. Some of the research and theory bearing on decision making and risk perception, driver situation awareness, and possible mediators of risk-taking is also analyzed here.

A Pragmatic and Semantic Analysis of EFL Learners’ Use of Modal Verbs: A Perception Study

The current study, which employed a new analysis approach -an explicit and implicit data collection method-, investigates the perception of the English modal verbs by forty-six Saudi EFL undergraduate learners. Findings revealed that Saudi EFL students struggled with the semantic functions of English modals more than the pragmatic ones. Deontic possibility modal verbs like can and might were the most challenging forms for the EFL learners. Functional complexity, input frequency, students’ L1 influence, and cultural variation were thought to cause students’ misunderstanding of these modals. Students, on the other hand, appeared to perceive the pragmatic functions with ease, reinforcing the role of the input frequency in the acquisition of English modality because modals of Request, Suggestion and Offer are frequently introduced to students in the classroom. Furthermore, findings revealed that students’ performance in the perception test was better than the explicit one, which could be attributed to the lack of explicit instruction of the English modals. Some pedagogical implications were suggested.

A survey on the pipeline evolution of facial capture and tracking for digital humans

With the introduction of concepts for virtual interaction and digital doubles, a rich scenario has been created for embodied avatars to strive. These avatars, more recently referred to as digital humans, have become a popular area of research, resulting in various techniques and methods that focus on improving the perception of their realism, fidelity, emphatic response, and interactivity. This survey aims to explore the literature and recent advancements on the key processes behind the creation and animation of digital human faces through the view of a general pipeline. The extensive review carried out in this study explores the usual data collection protocols, the main facial codification paradigms and databases, the approaches for digital human asset creation, facial tracking solutions for performance-driven animation, the solving process, and the final rendering delivery. Different quantitative evaluation methods, visual perception tests, and empathetic response evaluations for digital humans are also included in the survey. Additionally, the paper presents an updated summary of public and private frameworks for digital humans that go through the complete general pipeline presented. Finally, the condensed knowledge is discussed, inquiring into the possible direction of future developments in the field.

What is the prevalence of developmental prosopagnosia? An empirical assessment of different diagnostic cutoffs.

The prevalence of developmental prosopagnosia (DP), lifelong face recognition deficits, is widely reported to be 2-2.5%. However, DP has been diagnosed in different ways across studies, resulting in differing prevalence rates. In the current investigation, we estimated the range of DP prevalence by administering well-validated objective and subjective face recognition measures to an unselected web-based sample of 3116 18-55 year-olds and applying DP diagnostic cutoffs from the last 14 years. We found estimated prevalence rates ranged from .64-5.42% when using a z-score approach and .13-2.95% when using a percentile approach, with the most commonly used cutoffs by researchers having a prevalence rate of .93% (z-score, .45% when using percentiles). We next used multiple cluster analyses to examine whether there was a natural grouping of poorer face recognizers but failed to find consistent grouping beyond those with generally above versus below average face recognition. Lastly, we investigated whether DP studies with more relaxed diagnostic cutoffs were associated with better performance on the Cambridge Face Perception Test. In a sample of 43 studies, there was a weak nonsignificant association between greater diagnostic strictness and better DP face perception accuracy (Kendall's tau-b correlation, τb=.18 z-score; τb=.11 percentiles). Together, these results suggest that researchers have used more conservative DP diagnostic cutoffs than the widely reported 2-2.5% prevalence. We discuss the strengths and weaknesses of using more inclusive cutoffs, such as identifying mild and major forms of DP based on DSM-5.

An Error Analysis of the Perception Based on Accent in Japanese

Japanese has many words that have similar syllables but different meanings. However, for non-native speakers, these differences in meaning are quite difficult to spot as they can only be distinguished by tone also refers to accent. This study aims to analyze the misperception of accents in words with the same syllable. The data collected in this study were conducted through a perception test. These words were categorized based on the error types of the specified syllables. This study’s respondents are 20 students of the 3rd and 5th semester Japanese Department of Universitas Komputer Indonesia in the 2022/2023 academic year. The results showed that accent perception errors in respondents mostly occurred in Odaka accent patterns and many words with accents of 4 mora. Perception errors occur because students are unfamiliar with the vocabulary and accent patterns. This is related to the length of student learning.

Orbitofrontal syndrome in an offender incarcerated for aggravated kidnapping, rape and death of a minor

Orbitofrontal syndrome is characterized by disinhibition, impulsiveness, transgression of social norms and sometimes thedevelopment of criminal behavior. This is the case of an 18-year-old male offender incarcerated for kidnapping, rape andhomicide of a minor. He was evaluated through interviews and the use of the Eysenck personality questionnaire (Form B), Raven’s progressive matrices (RPM), Rey–Osterrieth complex figure (Form A), Differences perception test (FACES-R), Stroop color and word test (SCWT), Mini-Mental state examination (MMSE) and Aggression questionnaire (AGQ). The research subject showed age-appropriate speech, language and vocabulary, and had neither physical problems nor attention, language, writing, reading, praxis, calculation, perception and memory disorders. The results highlight a higher-than-average intelligencequotient, optimal cognitive skills, melancholic temperament with depressive thoughts, introverted personality with lowenvironmental sensitivity, poor social skills, self-absorption and avoidance. Additionally, perfectionist tendencies, suddenemotional changes, difficulty changing behavioral patterns, impulsiveness and disinhibition, all of which are characteristicsof orbitofrontal syndrome. Finally, the research highlights the use of psychometric tests and neuropsychological evaluationsfor the diagnosis of orbitofrontal syndrome. Said tests and evaluations are necessary for the proper management of offendersincarcerated in prisons and/or detention centers who do not have access to neuroimaging; moreover, they may be used to design strategic intervention programs.

Long-term auditory performance and psychosocial benefits of cochlear implantation in Mandarin-speaking older adults

PurposeAlthough previous studies have shown the efficacy of cochlear implants (CIs) in older adults, no study written in English has focused on Mandarin-speaking older recipients. Mandarin is a tonal language, it is hard to lip-read and tone recognition for CI users. This study aimed to evaluate the long-term post-CI outcomes in Mandarin-speaking older adults and the difference between them and younger recipients. Materials and methodsForty-six post-lingually deafened adults were included. Speech perception tests (vowel, consonant, disyllable words, Mandarin monosyllable recognition test, and categories of audiology performance were evaluated) and psychosocial scale were evaluated. ResultsThere were no significant differences between older and younger recipients in post-CI open-set speech perception. However, older recipients had significantly lower social and total scores in the subjective questionnaire than younger recipients. In both duration of deafness less than seven years and hearing years in life over 92.6 %, older recipients had no less capable speech perception than in younger. ConclusionMandarin-speaking older recipients can improve not only speech perception but also psychosocial benefits. Well hearing experience may confer an advantage to older recipients, despite their older implanted age. These results can help provide pre-CI consultation guidelines for older Mandarin-speaking recipients.

Gustatory dysfunction is related to Parkinson's disease: A systematic review and meta-analysis.

Olfactory dysfunction has been reported to be involved in Parkinson's disease (PD) pathogenesis. However, gustatory dysfunction in PD has not been evaluated as in-depth as olfactory dysfunction. We reviewed the previously published studies regarding gustatory function in PD patients and suggested the possibility that gustatory dysfunction may also be associated with PD. MEDLINE, Cochrane Library, Embase, and PubMed databases were searched for studies evaluating gustatory function in PD patients. We used the standardized mean difference and a 95% confidence interval (CI) as the effect analysis index regarding the taste strip test. The relative risk and 95% CI were used as the effect analysis index for the questionnaires and propylthiouracil (PTU)/phenylthiocarbamide (PTC) perception test. Statistical heterogeneity was assessed using forest plots, Cochran's Q, and the I2 statistic; heterogeneity was considered high when I2 was over 75%. Publication bias was assessed by funnel plots and the Egger bias test. We identified 19 articles that reported the results of gustatory function tests in PD patients and healthy controls. Most of these studies used various gustatory tests, including taste strips, questionnaires, taste solutions, PTU/PTC perception tests, and electrogustometry, and reported significantly lower gustatory function in PD patients than in the controls. However, several articles reported contradictory results. Based on these studies, gustatory dysfunction is closely related to PD. However, the number of studies and enrolled subjects was small, and a unified gustatory function test was lacking. Therefore, further studies with larger populations and normalized gustatory function tests are needed.

Analysis and computational modelling of Emirati Arabic intonation – A preliminary study

This study is a preliminary investigation of intonation in Emirati Arabic (EA) (an under-researched Arabic dialect), using systematic acoustic analysis and computational modelling. First, we investigated the prosodic realisation of information focus and contrastive focus at sentence-initial, -penultimate and -final positions. The analysis of 1980 EA utterances produced by eleven EA native speakers revealed that (1) in focused words, only contrastive focus is realised with expanded excursion size, longer duration, and stronger intensity relative to their neutral focus counterparts, (2) post-focus words have a lower f0 and weaker intensity in both contrastive focus and information focus, and (3) pre-focus words have compressed excursion size and relatively short duration. We then used computational modelling to test how much of the EA intonation could be captured by the PENTA model, with focus-defined functional categories and a number of other, putative categories. PENTAtrainer was trained on syllable-sized multi-functional targets from a subset of the production data. The model then generated f0 contours with the learned targets and imposed them on resynthesised speech for perceptual evaluation. A comparison of the model-generated f0 contours with the natural f0 contours showed that not only focus but also weight, stress, position of word-level stressed syllable and prosodic word are important factors determining the fine details of EA intonation. A perceptual test with native EA listeners showed that the synthetic EA f0 contours sounded nearly as natural as the original intonation, and could convey focus nearly as accurately as natural intonation.

The Effects of STEM Activities Conducted with the Flipped Learning Model on Primary School Students’ Scientific Creativity, Attitudes and Perceptions towards STEM

The aim of this study is to determine the effects of STEM activities carried out with the flipped learning model within the scope of science class on the scientific creativity, perceptions about STEM, and attitudes towards STEM of 4th grade primary school students and to reveal students’ opinions about the learning process. The sample of this study consisted of 57 fourth grade students attending a public primary school in a city center in the Eastern Black Sea region in the spring semester of the 2021-2022 academic year. Mixed method was used in the study. Quasi-experimental method with experimental and control groups was used in the quantitative dimension of the study, and case study was used in the qualitative dimension. In the study, data were collected using the “Scientific Creativity Scale”, “STEM Attitude Scale”, “STEM Perception Test” and a “semi-structured interview form” developed by the researcher. SPSS 21 package program was used to analyze the collected quantitative data and content analysis was used to analyze the qualitative data. The quantitative results of the study revealed that STEM activities conducted with the Flipped Learning Model had a positive effect on students’ scientific creativity levels and STEM perceptions, but had no effect on their attitudes towards STEM. The qualitative results of the study revealed that students mostly found the activities useful, instructive and fun. In line with the results obtained from the study, the use of STEM activities supported by the Flipped Learning model is recommended at all levels of education.

Raising business communication students’ awareness of nonverbal features of interaction

Analysis of conversations between international university students in the Corpus of English as a Lingua Franca Interaction (CELFI, McDonough & Trofimovich, 2019) has demonstrated that holds, which are temporary cessations of dynamic movement, are a robust visual cue of nonunderstanding that can be reliably interpreted by external observers as signals of listener comprehension difficulties (e.g. McDonough et al., 2019, 2022, 2023). Using CELFI materials, this study used an experimental design to explore whether business communication students (N = 64) benefit from instructional activities designed to raise their awareness of holds as a signal of nonunderstanding. The students carried out perception tests in Week 1 and Week 5 that presented video excerpts from CELFI showing the depicted listeners’ hold onsets and releases, and the students rated those listeners’ comprehension. In the interim, 31 students completed weekly awareness-raising activities via Moodle (2 hours per week) for four weeks. A mixed ANOVA showed that students who participated in the awareness-raising activities showed significant improvement in their ability to discriminate between hold onsets and releases. Implications for the use of awareness-raising activities to promote recognition of nonverbal behavior are discussed.

Funkční hodnocení laryngoskopického vyšetření a souvislost s kvalitou hlasu a parametry hlasového pole

Summary Introduction: Previous laryngoscopy evaluation protocols have mostly focused on assessment of glottal status and morphological description of vocal folds’ shape and oscillations. The basic functional manifestations of laryngeal use, according to new protocols, include a description of supraglottic laryngeal activity. Methods: Laryngoscopic evaluation was performed as a perceptual test, performed online, using a web-based application. The degree and type of glottal insufficiency and the degree of anterior, posterior compression and lateral-medial (L-M) compression separately for each side were evaluated by a total of 15 respondents in a total of 26 video recordings of laryngoscopic examinations. In addition, the correlations between listening evaluations of the voice using modified GRBAS scales and voice range profile parameters were investigated. Results: The ratings of the laryngoscopic scales had well to excellent agreement. Agreement for type of insufficiency was just moderate. The associated ratings of L-M compression on the right and left sides showed correlations. For listening evaluation, medial compression was found to be related to the perception of habitual voice strain, and to strain and instability in the pitch range of the change of registers of the singing voice. Degree of insufficiency predicted less fullness of habitual voice in general but was also related to vocal dyspnea and weakness when calling. At the same time, it was largely responsible for the deterioration of the quality of the singing voice. Medial compression systematically reduced pitch range and the area of the voice range profile. Conclusion: The results of the perceptual evaluation can be used in further education. On their basis, didactic material for training the assessment of supraglottic laryngeal activity was prepared and published in the form of an online tutorial. The degree of insufficiency generally affects various characteristics of the speaking and singing voice. Medial compression systematically affects only the strain of the speaking voice, while in the singing voice it accentuates the strain and instability of the transitional region between registers and impairs the production of high pitches. Key words laryngoscopy – visual evaluation – voice range profile – GRBAS
