The Speech-to-Speech Synchronization task is a well-established behavioral approach to assess individual differences in auditory-motor synchronization. In this task, participants listen to a series of syllables that progressively increase in frequency, while simultaneously whispering the syllable /ta/ to synchronize with the rhythm of the incoming syllables. In our study, we replicated the bimodal distribution of high- and low-synchronizers in a sample of native German speakers. We present a refined analysis pipeline based on existing analysis scripts, address minor task-related issues and observations, and incorporate new analysis features such as the removal of silent gaps. Crucially, our analysis revealed that (sub-)harmonic interactions can emerge during various stages of synchronization and its assessment, obscured by the synchronization measurement. Subharmonic synchronizers were found to produce the /ta/-syllables to only every second or third incoming syllable which can result in deceptively high Phase Locking Values, thus challenging the conceptualization of low- and high-synchronizers. Our data analysis is available at OSF.

In multiagent systems, learning optimal behavior policies for individual agents remains a challenging yet crucial task. While recent research has made strides in this area, the issue of when agents should maintain consistent behaviors with one another is still not adequately addressed. This article proposes a novel approach to enable agents to autonomously decide whether their behaviors should align with those of their peers by leveraging intrinsic rewards to optimize their policies.

This research paper explores the role of speaker, listener and real-time social attention for pronoun comprehension in autistic and nonautistic children in northeast United States. We assessed the pronoun comprehension of 22 autistic children (average age of 62 months, range 46-80 months) and 22 nonautistic children (average age 44 months, range 30-57 months) matched on expressive vocabulary scores. We evaluated first- and second-person possessive pronoun comprehension ("my" and "your") using a game in which two experimenters hid stickers and provided clues to their location by providing a verbal clue (e.

Human factors are central to aviation safety, with pilot cognitive states such as workload, stress, and situation awareness playing important roles in flight performance and safety. Although flight simulators are widely used for training and scientific research, they often lack the ecological validity needed to replicate pilot cognitive states from real flights. To address these limitations, a new in-flight data collection methodology for general aviation using a Cessna 172 aircraft, which is one of the most widely used aircraft for pilot training, is presented.

Background: Metamemory is the awareness of and ability to evaluate one's own cognitive abilities. This study examined impaired metamemory as a possible mechanism contributing to persistent cognitive symptoms after COVID-19.
Methods: Individuals with previous COVID-19 illness were recruited.

Introduction: This study utilized electroencephalography (EEG) to compare brain functional and effective connectivity patterns in children with reading difficulties (RD) and math difficulties (MD) during specific tasks. The aim was to identify neurophysiological distinctions between these two learning disorders, which often exhibit high comorbidity.
Methods: Data from a publicly available dataset of 28 children (11 RD, 17 MD) aged 7-13 years were analyzed.
