Internal and external factors explaining variability in children’s word definition skills: A scoping review protocol

AbstractObjective: The objective is to provide a detailed protocol for a scoping review aimed at mapping and summarizing studies of word definition (WD) skills in children, in clinical and non-clinical populations. More specifically, the aim is to map which factors have been studied as associated with WD skills. Furthermore, the scoping review will summarize the methodological characteristics of t

Are Pairs More Attentive Towards Feedback Than Individuals? A Glance into Feedback Neglect for Middle-School Students Using an Educational Game in History

Critical constructive feedback (CCF), is said to be a key ingredient in learning. However, if and how learners engage in CCF is rarely studied in collaborative learning situations. This study aims to filling this research gap by analyzing data logs from dyads of middle school students using an educational game in history, evaluating their inclination to dismiss or attend to feedback when making er

Analysis of modulations of mental fatigue on intra-individual variability from single-trial event related potentials

Background: Intra-individual variability (IIV), a measure of variance within an individual's performance, has been demonstrated as metrics of brain responses for neural functionality. However, how mental fatigue modulates IIV remains unclear. Consequently, the development of robust mental fatigue detection methods at the single-trial level is challenging. New methods: Based on a long-duration flan

Crosslinguistic Differences in Food Labels Do Not Yield Differences in Taste Perception

Research has shown that speakers of different languages may differ in their cognitive and perceptual processing of reality. A common denominator of this line of investigation has been its reliance on the sensory domain of vision. The aim of our study was to extend the scope to a new sense—taste. Using as a starting point crosslinguistic differences in the category boundaries of edible bulbs, we ex

Estimation of Impulse Responses for a Moving Source Using Optimal Transport Regularization

The estimation of impulse responses (IRs) is fundamental to various audio applications, including active noise control, telecommunication, and sound zone control. Despite its long history, estimating impulse responses remains challenging when dealing with short signals and with signals having poor spectral excitation. However, in many applications the source is moving such that one has access to s

Impulse Response Interpolation Using Optimal Transport

The spatial impulse response (IR) interpolation problem is of general interest, e.g. for imaging of subsurface structures based on seismic waves, rendering of audio and radar IRs, as well as for numerous spatial audio applications. A commonly used model represents the occurring reflections as equivalent source positions, often being determined using a sparse re-construction framework employing spa

Teachers’ descriptions of classroom communication after an SLP-led in-service training

Purpose: The aim of this study is to explore teachers’ experience and understanding of classroom communication after participating in a speech-language pathologist (SLP) led in-service training on classroom communication. Method: This qualitative study used a focus group approach to explore how teachers describe their classroom communication. Twenty primary-school teachers participated. Thematic a

Neural semantic effects of tone accents

This study investigated whether the brain utilizes morphologically induced tones for semantic processing during online speech perception. An auditory comprehension task was conducted while measuring event-related potentials (ERPs). The study tested whether a discrepancy between contextual expectations and the tonal realizations of the target word would yield an N400 effect, indicative of semantic

From Weak to Strong Sound Event Labels using Adaptive Change-Point Detection and Active Learning

We propose an adaptive change point detection method (A-CPD) for machine guided weak label annotation of audio recording segments. The goal is to maximize the amount of information gained about the temporal activations of the target sounds. For each unlabeled audio recording, we use a prediction model to derive a probability curve used to guide annotation. The prediction model is initially pre-tra

Thinking for speaking

This chapter provides an overview of current research on thinking-for-speaking and second language acquisition. The Thinking-for-Speaking hypothesis (Slobin, 1996) posits that whilst in the process of producing speech, speakers channel their attention according to the linguistic categories of their language. As a result, speakers of different languages think differently during speech production. W

Semantics and cognition : Spatiotemporal metaphors and time perception in L2 users

This chapter reviews the available empirical evidence for a universal metaphoric structure such as TIME IS SPACE and its effects on temporal cognition in L2 users. The chapter covers previous experimental evidence that lends support to the psychological reality of the TIME IS SPACE metaphor, while also revealing cross-linguistic differences in how this fundamental metaphor is instantiated across t

The Effect of COVID-Related Quarantine and Attitudes on Time Conceptualization : Evidence From Temporal Focus and Implicit Space-Time Mappings

The temporal focus hypothesis (TFH) entails that individuals who value the past tend to conceptualize it in front, whereas individuals who value the future tend to map the future in front instead (de la Fuente et al., 2014). This varies as a function of culture, individual differences, and context. Here, we extend this line of inquiry by testing a contextual variable, namely COVID-19 quarantine st

Vocal, Visual, and Tactile Signals in Cat–Human Communication : A Pilot Study

To investigate multimodal signals in cat–human communication we recorded 36 cat–owner interactions in everyday situations that were judged by the owners for valence (negative, mixed or positive). We then coded the videos for behaviour using an ethogram including vocal, visual and tactile (multimodal) signals. Vocalisations were segmented and acoustic measures of duration and F0 obtained. In cats,

Structural MRI findings in the brain related to pain distribution in chronic overlapping pain conditions : An explorative case–control study in females with fibromyalgia, temporomandibular disorder-related chronic pain and pain-free controls

Background: Few neuroimaging studies have investigated structural brain differences associated with variations in pain distribution. Objective: To explore structural differences of the brain in fibromyalgia (FM), temporomandibular disorder pain (TMD) and healthy pain-free controls (CON) using structural and diffusion MRI. Methods: A case–control exploratory study with three study groups with diffe

Spatial resolution and optical sensitivity in the compound eyes of two common European wasps, Vespula germanica and Vespula vulgaris

Vespula germanica and Vespula vulgaris are two common European wasps that have ecological and economic importance as a result of their artificial introduction into many different countries and environments. Their success has undoubtedly been aided by their capacity for visually guided hunting, foraging, learning and using visual cues in the context of homing and navigation. However, the visual sys

Context Effects on Duration, Fundamental Frequency, and Intonation in Human-directed Domestic Cat Meows

In this study, we investigated the prosody of domestic cat meows produced in different contexts. Prosodic cues – i.e., variation in intonation, duration, voice quality and fundamental frequency – in humans as well as in nonhuman animals carry information about idiosyncratic traits of the signaller, including sex, age, and physical and mental state. The duration, fundamental frequency (F0) and into

Capturing life as it is truly lived? Improving diary data in educational research

Diary methods have long been used as pedagogic tools in learning, and as part of reflective practice in teacher education, but less often as data collection instruments in educational research. This is in part due to implementation challenges emerging from the time and literacy demands they place on participants. To illustrate the use of diary methods in educational research, we juxtapose two diar
