Electrophysiological Correlates of Intensity Resolution Under Forward Masking
2010
Nonsimultaneous masking can severely impair auditory intensity resolution, but the effect strongly depends on the stimulus configuration. For example, an intense forward masker causes a pronounced impairment in intensity resolution for standards presented at intermediate levels, but not for standards presented at low and high levels, resulting in a midlevel hump pattern (Zeng et al., Hear Res 55:223-230, 1991). Several aspects of the phenomenon cannot be explained by mechanisms in the auditory periphery. For instance, backward maskers cause midlevel humps at least as large as the humps caused by forward maskers. The present experiment was aimed at studying the relation between the effects o…
Il silenzio come pratica di cura nella relazione educativa
2014
In un tempo, come quello in cui agiamo e viviamo, consegnato all’effimero e alla fugacità, il silenzio si riafferma come bisogno formativo e acquista un ruolo di primo piano all’interno del dialogo educativo, come una pratica di cura attraverso cui l’uomo contemporaneo possa contrastare la banalità della chiacchiera e di un’esistenza vissuta in modo inautentico. Se il Novecento pedagogico ha riscoperto il valore educativo del silenzio, oggi tale pratica viene riproposta non solo come atto di tacere, ma anche come apertura di un nuovo orizzonte di senso dentro cui accogliere l’altro, cioè ospitarlo. Vincendo la paura del vuoto, da sempre identificato col nulla, il silenzio non viene più inte…
Kontemplativ, handlingsrettet spiritualitet - Stille stund og ledelse i Oxfordbevegelsen belyst ved nedtegnelser fra Erling Wikborg
2014
Author's version of an article in the journal: Teologisk tidsskrift. Also available from the publisher at: http://www.idunn.no/tt/2014/04/kontemplativ_handlingsrettet_spiritualitet_-_stille_stund_ Contemplation and belief in guidance from God had a distinct design in the international ecumenical revival the Oxford Group which gained great support in the interwar period. In this movement, contemplation, called quiet time, was focused on intention and action in order to grasp and carry out God’s guidance. The article examines teaching about and practice of quiet time and guidance in the Oxford Group and shows how these phenomena relate to a broader historical context within Christianity. Note…
Activity of bulbar respiratory modulated neurons and restart of respiration after hypocapnic apnea in rabbits
1980
The activity of respiratory modulated neurons at the end of the apneic pause and during restart of respiration and the diaphragmatic mass activity were examined and both were compared to quiet respiration. Thresholds of mutual inhibition of neurons are unevenly distributed within various phase types of neurons.
Ventilatory conditioning by self-stimulation in rats: A pilot study
1994
International audience; This article describes an experimental attempt to condition breathing pattern in rats. In this experiment, a freely moving rat was first rewarded by an electrical stimulation of the medial forebrain bundle whenever inspiratory duration (TI) exceeded 300 ms. A bidirectional control was then used: TIs longer than 400 ms were rewarded, and then TIs shorter than 300 ms were rewarded. The frequency of TIs longer than 300 ms increased when this event was rewarded, further increased when TIs above 400 ms were rewarded, and decreased during reversal conditioning (TI < 300 ms). At the beginning of the experiment, stimulation caused increased arousal and motor activity, but af…

Temporal loudness weights in background noise: Data and models
2019
Previous studies consistently showed that human listeners primarily consider the beginning of a time-varying sound when judging its overall loudness, and place less weight on subsequent temporal portions. However, all experiments studying this primacy effect in temporal loudness weights presented the target sound in quiet. Here, we compared temporal weights when the target sound was either presented in quiet or in a continuous background noise, and for a variation in the level of the target sound across a range of 60 dB. The target sound was a time-varying narrowband noise, the background noise was a continuous bandpass-filtered noise. In all conditions, we observed the expected primacy eff…
Community response to environmental noise in Valencia
1990
Abstract In Valencia, Spain, 263 residents were interviewed at five different locations in order to investigate the subjective response to environmental noise in urban areas. External noise levels were measured over five consecutive days at each site. Noise levels were high in two of the selected sites ( L eq 24h about 75 dBA) and lower in the other two ( L eq 24h about 65 dBA). The fifth location had a night noise problem because of the presence of many leisure places (pubs, restaurants, etc.). The scores of the sample with their satisfaction with their neighbourhood were notably higher in the quiet than in the noisy areas (83% and 64% respectively). Road traffic and pub noise (in the fift…
Cisza i milczenie w modlitwie i liturgii Kościoła
2022
Zagadnienie ciszy jest czymś niezwykłym. Chociaż może się wydawać, że to zjawisko nie ma żadnej wartości, to jednocześnie kryje w sobie ogromny potencjał dostępny dla każdego człowieka. Zewnętrzna cisza oraz milczenie przede wszystkim mogą służyć wewnętrznemu wyciszeniu. To umożliwia głębsze poznanie własnych przeżyć, emocji i myśli oraz nadanie im właściwej wartości. Niemożliwe jest pełne słuchanie, bez głębokiego skupienia. Te elementy są istotne również dla modlitwy chrześcijańskiej. Odpowiedni klimat ciszy może służyć skupieniu, bez którego nie można wyobrazić sobie właściwej modlitwy. Dodatkowo postawa milczenia otwiera człowieka na transcendencję. W ciszy szczególnie doświadcza się og…
Frontal Electroencephalogram Alpha Asymmetry during Mental Stress Related to Workplace Noise
2021
This study aims to investigate the effects of workplace noise on neural activity and alpha asymmetries of the prefrontal cortex (PFC) during mental stress conditions. Workplace noise exposure is a pervasive environmental pollutant and is negatively linked to cognitive effects and selective attention. Generally, the stress theory is assumed to underlie the impact of noise on health. Evidence for the impacts of workplace noise on mental stress is lacking. Fifteen healthy volunteer subjects performed the Montreal imaging stress task in quiet and noisy workplaces while their brain activity was recorded using electroencephalography. The salivary alpha-amylase (sAA) was measured before and immedi…
