This database provides a validated set of sentences designed for research on ethnic stereotyping and social cognition. The materials are suitable for use in EEG/ERP experiments, neuroimaging studies (fMRI, MEG), behavioral paradigms, and computational/LLM modelling of social bias. The stimuli were validated on a native Italian-speaking population. The database consists of 330 sentence–word pairs organized across three experimental conditions: • Incongruent (N = 110): sentences in which the terminal target word violates the ethnic stereotype associated with the speaker's accent (e.g., a speaker with an African accent described as a pilot or a surgeon) • Congruent (N = 110): sentences in which the terminal word is consistent with prevailing ethnic stereotypes (e.g., a speaker with an African accent described as working in a field or selling items at a market stall) • Neutral (N = 110): control sentences mentioning Italian individuals or regional groups, with no ethnic accent or stereotype content Sentences are distributed across seven ethnic/accent categories: African, Chinese, Roma/Sinti, Eastern European, Asian, Latin American, and Arabian. All three conditions are matched on the following variables: • Sentence length in characters • Sentence length in words • Terminal word length in characters • Lexical frequency of the terminal word • Grammatical category and imageability of the terminal word • Gender of the protagonist (male / female / mixed) Intended uses • EEG/ERP studies of stereotyping, social prediction, and language processing (N400, LAN, LP components) • Neuroimaging (fMRI/MEG) studies of social cognition and predictive coding • Behavioral studies of implicit ethnic bias, semantic priming, and accent perception • Training, testing, or probing Large Language Models (LLMs) on social bias, world knowledge and stereotype content Availability of auditory stimuli A professionally recorded auditory version of these stimuli (sentences spoken with native-accented voices across the seven ethnic/accent categories) is also available. Auditory stimuli are not shared openly, but may be made available to research groups for non-profit academic purposes under a co-authorship agreement: groups wishing to use the auditory materials in a study intended for publication are invited to contact the authors to discuss the terms of scientific collaboration, which will include co-authorship on any resulting paper.

The questionnaire is designed to assess dysexecutive symptoms associated with both acute and chronic exposure to high-altitude hypoxia. It investigates multiple cognitive domains related to dorsolateral prefrontal cortex functioning, including attention, planning, working memory, cognitive flexibility, and judgment, through targeted questions focused on climbers’ subjective experiences in extreme environments. As well known, executive functions and higher-order cognitive control are critically supported by prefrontal cortex networks (Badre & Nee, 2018; Knight & D’Esposito, 1999; Knight et al., 1995; Miller & Cohen, 2001; Jiang et al., 2025), and are particularly vulnerable to environmental stressors such as hypoxia. Environmental hypoxia, resulting from reduced oxygen supply, poses a significant risk of dysfunctioning and damaging the neurocognitive system, particularly in relation to anxiety and stress. Inadequate oxygenation can lead to acute and chronic brain damage. Scholars used behavioral, hemodynamic, and electromagnetic neurofunctional techniques to investigate the effects of normobaric and hypobaric hypoxia on neurocognitive systems. They found a correlation between hypoxia, altered psychomotor responses, and changes in neurocognitive functions Borden et al., 2024; Huang et al., 2026; Suzin et al., 2020; Wang et al., 2021; Yan et al., 2011). Prolonged exposure exacerbates these effects, resulting in compensatory delayed behavioral responses and alterations in behavioral monitoring and conflict inhibitory control. Thus, neurocognitive function and integrity are under stress. These changes illustrate the spectrum from sensory detection to more complex cognitive processing, highlighting the brain efficiency in managing information (McMorris et al., 2017; Zani et al., 2023, 2024, 2025). The present project proposes that high altitude (HA) level reached, repetitions of such reaching, and the duration of permanence at a specific HA, may be positively related to impairments and alterations of both neurocognitive structures and functions. We shall examine whether the proposed relationships among the mentioned variables really exist studying the self-reported, subjectively perceived experiences of skilled mountaineers who summited at least high altitude (HA) peaks of at least 6,500 m. The present battery comprises 43 brief situational and environmental scenarios administered via Google Forms, each requiring the selection of a single response option. All scenarios are designed to be mutually independent. With the exception of scenarios #13 and #19, which each provide five response options, all other scenarios offer three alternatives. The battery requires approximately 10 minutes to complete. Inclusion criteria for participating to data collection: having summited at least three peaks exceeding 6,500 m (including at least one ascent exceeding 8,000 m) within the past 10 years without the use of supplemental oxygen.

This dataset contains experimental data used in the manuscript: Electrochemical Impedance Spectroscopy as a tool for diagnosing reactive species in plasma-treated water. The dataset includes electrochemical impedance spectroscopy (EIS) measurements, calibration data for NaCl, HNO3 solutions and Plasma treated water, plasma discharge power data, and chemical properties of plasma-treated water (pH, concentration of NO2-, NO3- by multimeter). EIS measurements were performed in the frequency range 0.1 Hz to 10 kHz using an MFIA impedance analyzer. Plasma-treated water was prepared under different discharge currents and treatment times. Sheets included in the dataset, 1-Impedance data for plasma-treated water, 2- Calibration data for NaCl solutions at different concentrations, 3- Calibration data for HNO3 acid solutions, 4-Electrical parameters of plasma discharge, 5-Impedance parameters (fmax, Im(Y), Gm, Q, alpha) for all samples in two different setups, 6- Chemical measurements including pH, concentration of NO2- by Griess assay and NO3- measured by multimeter.
