Estimating physiological arousal with pupil size and skin conductance

In the fields of behavioural and psychological research, pupil size and skin conductance are two variables that provide useful information about a participant’s state of mind at a given moment. Both variables are involuntary indicators of psychophysiological responses such as alertness, arousal, or focus. Pupil size is commonly measured with a video-based eye tracker, and skin conductance is measu

Sensory feedback in upper limb prosthetics : advances and challenges

Advanced sensory feedback from upper limb prostheses would provide multiple benefits to people with upper limb amputations, but achieving functional and natural-feeling sensation is technologically challenging. Advances are being made with invasive and non-invasive stimulation approaches, but considerable challenges need to be addressed with technological innovation.

Children's use of English as lingua franca in Swedish preschools

This paper highlights a current phenomenon reported from preschools placed in multilingual areas in Sweden, namely that some preschoolers with mutually different language backgrounds sometimes use English as lingua franca instead of Swedish during play. The data stems from a study of language environments in Swedish preschools situated in both monolingual and multilingual areas. The analyses revea

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

Semantic processing of verbal narratives compared to semantic processing of visual narratives : an ERP study of school-aged children

There is a misconception that pictures are easy to comprehend, which is problematic in pedagogical practices that include pictures. For example, if a child has difficulties with verbal narration to picture sequences, it may be interpreted as specific to spoken language even though the child may have additional difficulties with comprehension of visual narratives in the form of picture sequences. T

Reconfiguration of cognitive control networks during a long-duration flanker task

Continuous task engagement generally leads to vigilance decrement and deteriorates task performance. However, how conflict effect is modulated by vigilance decrement has no consistent evidence, and little is known about the underlying neural mechanisms. Here we adopted an electroencephalogram dataset collected during a prolonged flanker task to examine the interactions between vigilance and congru

Children’s development of semantic verbal fluency during summer vacation versus during formal schooling

Purpose: Children’s results on school-related achievements tests, such as aspects of math, reading and writing, have been shown to decline following a lengthy summer vacation. Few studies have investigated whether this also applies to vocabulary skills. The purpose of this study is to investigate how lexical organization and retrieval, assessed by a semantic verbal fluency (SVF) task, develops dur

An exploratory study of teachers’ supportive communication during interactive book reading in the classroom

This study examines teachers’ use of evidence-based language learn­ing techniques in the classroom and possible impact on student ­engagement. Video recordings of nine primary school teachers conducting interactive book reading with their students were analyzed both according to the Communication Supporting Classroom Obser­vation Tool-Language Learning Interactions (CSCOT-LLI) and descriptively.

A Deep Learning Biomimetic Milky Way Compass

Moving in straight lines is a behaviour that enables organisms to search for food, move away from threats, and ultimately seek suitable environments in which to survive and reproduce. This study explores a vision-based technique for detecting a change in heading direction using the Milky Way (MW), one of the navigational cues that are known to be used by night-active insects. An algorithm is propo

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

Degree of Breathiness in a Synthesized Voice Signal as it Differentiates Masculine versus Feminine Voices

Introduction: Most studies determining speakers’ perceived gender as binarily female or male are reliant on F0 perception, although other vocal parameters may also contribute to the perception of gender. The current study focused on the impact of breathiness on the perception of speakers’ gender as a biological variable (feminine or masculine). Methods: n = 31 normal hearing, native English speake

A model of decentralized vision in the sea urchin Diadema africanum

Sea urchins can detect light and move in relation to luminous stimuli despite lacking eyes. They presumably detect light through photoreceptor cells distributed on their body surface. However, there is currently no mechanistic explanation of how these animals can process light to detect visual stimuli and produce oriented movement. Here, we present a model of decentralized vision in echinoderms th

Data-Driven Campaigning in Data-Dense Small Multiparty Systems: A Party-Level Analysis

This study examines data-driven campaign (DDC) practices in Sweden. We explore the extent of data-driven practices adopted in Swedish political campaigns, and parties’ motivations to adopt them. Since this is a comparison of domestic parties, we test the importance of four party-level factors—resources, structure, attitudes toward data use, and ideology—using extensive interviews with key campaign

Silent score reading : Four Swedish choral conductors’ conceptions, processes, and strategies

In research on music conducting, there is a lack of studies concerning conductors’ score-reading. The present investigation explored the reading strategies of four Swedish choral conductors. Two interconnected studies addressed the conductors’ explicit conceptions about score reading and their silent-reading strategies in actual reading situations. All conductors emphasized overviewing and script-

Dim-light colour vision in the facultatively nocturnal Asian giant honeybee, Apis dorsata

We discovered nocturnal colour vision in the Asian giant honeybee Apis dorsata - a facultatively nocturnal species - at mesopic light intensities, down to half-moon light levels (approx. 10 -2 cd m -2). The visual threshold of nocturnality aligns with their reported nocturnal activity down to the same light levels. Nocturnal colour vision in A. dorsata is interesting because, despite being primari

Eye movements in visual impairment

This Special Issue describes the impact of visual impairment on visuomotor function. It includes contributions that examine gaze control in conditions associated with abnormal visual development such as amblyopia, dyslexia and neurofibromatosis as well as disorders associated with field loss later in life, such as macular degeneration and stroke. Specifically, the papers address both gaze holding
