Climate change during the COVID-19 outbreak: scoping future perspectives.

Environ Sci Pollut Res Int 2021 May 2. Epub 2021 May 2.

Department of Economics and Business Administration, Art & Social Sciences Division, University of Education Lahore (Faisalabad Campus), Faisalabad, Pakistan.

Neither war nor recession or any kind of prior disaster has been considered a prelude to the looming threat of climate change over the past era as coronavirus (hereafter COVID-19) has in only a few months. Although numerous studies have already been published on this topic, there has not been compelling evidence critically assessing the impact of COVID-19 by and on climate change. The present study fills this gap by taking a more holistic approach to elaborate factors, e. Read More

Slow Resting State Fluctuations Enhance Neuronal and Behavioral Responses to Looming Sounds.

Brain Topogr 2021 Mar 25. Epub 2021 Mar 25.

Royal's Institute of Mental Health Research, University of Ottawa, 1145 Carling Avenue, Ottawa, ON, K1Z 7K4, Canada.

We investigate both experimentally and using a computational model how the power of the electroencephalogram (EEG) recorded in human subjects tracks the presentation of sounds with acoustic intensities that increase exponentially (looming) or remain constant (flat). We focus on the link between this EEG tracking response, behavioral reaction times and the time scale of fluctuations in the resting state, which show considerable inter-subject variability. Looming sounds are shown to generally elicit a sustained power increase in the alpha and beta frequency bands. Read More

Auditory roughness elicits defense reactions.

Sci Rep 2021 Jan 13;11(1):956. Epub 2021 Jan 13.

CNRS, Ircam, Sorbonne Université, Ministère de la Culture, Sciences et Technologies de la Musique et du son, STMS, 75004, Paris, France.

Auditory roughness elicits aversion, and higher activation in cerebral areas involved in threat processing, but its link with defensive behavior is unknown. Defensive behaviors are triggered by intrusions into the space immediately surrounding the body, called peripersonal space (PPS). Integrating multisensory information in PPS is crucial to assure the protection of the body. Read More

Condition-dependent responses of fish to motorboats.

Biol Lett 2020 11 18;16(11):20200401. Epub 2020 Nov 18.

School of Biological Sciences, University of Bristol, 24 Tyndall Avenue, Bristol BS8 1TQ, UK.

Anthropogenic noise is a pollutant of global concern that has been shown to have a wide range of detrimental effects on multiple taxa. However, most noise studies to-date consider only overall population means, ignoring the potential for intraspecific variation in responses. Here, we used field experiments on Australia's Great Barrier Reef to assess condition-dependent responses of blue-green damselfish () to real motorboats. Read More

A High-Dimensional Quantification of Mouse Defensive Behaviors Reveals Enhanced Diversity and Stimulus Specificity.

Curr Biol 2020 Dec 1;30(23):4619-4630.e5. Epub 2020 Oct 1.

Division of Neuroscience and Experimental Psychology, School of Biological Science, Faculty of Biology, Medicine and Health, University of Manchester, Manchester, UK.

Instinctive defensive behaviors, consisting of stereotyped sequences of movements and postures, are an essential component of the mouse behavioral repertoire. Since defensive behaviors can be reliably triggered by threatening sensory stimuli, the selection of the most appropriate action depends on the stimulus property. However, since the mouse has a wide repertoire of motor actions, it is not clear which set of movements and postures represent the relevant action. Read More

Proximal Binaural Sound Can Induce Subjective Frisson.

Front Psychol 2020 3;11:316. Epub 2020 Mar 3.

Faculty of Environment and Information Studies, Keio University, Fujisawa, Japan.

Auditory frisson is the experience of feeling of cold or shivering related to sound in the absence of a physical cold stimulus. Multiple examples of frisson-inducing sounds have been reported, but the mechanism of auditory frisson remains elusive. Typical frisson-inducing sounds may contain a looming effect, in which a sound appears to approach the listener's peripersonal space. Read More

Frontal cortex selectively overrides auditory processing to bias perception for looming sonic motion.

Brain Res 2020 01 10;1726:146507. Epub 2019 Oct 10.

University of Tennessee Health Sciences Center, Department of Anatomy and Neurobiology, Memphis, TN, USA.

Rising intensity sounds signal approaching objects traveling toward an observer. A variety of species preferentially respond to looming over receding auditory motion, reflecting an evolutionary perceptual bias for recognizing approaching threats. We probed the neural origins of this stark perceptual anisotropy to reveal how the brain creates privilege for auditory looming events. Read More

Social coding of the multisensory space around us.

R Soc Open Sci 2019 Aug 7;6(8):181878. Epub 2019 Aug 7.

CNRS, Ircam, Sorbonne Université, Ministère de la Culture, Sciences et Technologies de la Musique et du son, STMS, F-75004 Paris, France.

Multisensory integration of stimuli occurring in the area surrounding our bodies gives rise to the functional representation of peripersonal space (PPS). PPS extent is flexible according to the affective context and the target of an action, but little is known about how social context modulates it. We used an audiotactile interaction task to investigate PPS of individuals during social interaction. Read More

Remapping Peripersonal Space by Using Foot-Sole Vibrations Without Any Body Movement.

Psychol Sci 2019 10 23;30(10):1522-1532. Epub 2019 Sep 23.

Department of Computer Science and Engineering, Toyohashi University of Technology.

The limited space immediately surrounding our body, known as peripersonal space (PPS), has been investigated by focusing on changes in the multisensory processing of audio-tactile stimuli occurring within or outside the PPS. Some studies have reported that the PPS representation is extended by body actions such as walking. However, it is unclear whether the PPS changes when a walking-like sensation is induced but the body neither moves nor is forced to move. Read More

The time course of auditory looming cues in redirecting visuo-spatial attention.

Sci Rep 2019 01 24;9(1):743. Epub 2019 Jan 24.

Max Planck Institute for Biological Cybernetics, Department Human Perception, Cognition, and Action, Tübingen, 72076, Germany.

By orienting attention, auditory cues can improve the discrimination of spatially congruent visual targets. Looming sounds that increase in intensity are processed preferentially by the brain. Thus, we investigated whether auditory looming cues can orient visuo-spatial attention more effectively than static and receding sounds. Read More

Enhanced audio-tactile multisensory interaction in a peripersonal task after echolocation.

Exp Brain Res 2019 Mar 7;237(3):855-864. Epub 2019 Jan 7.

U-VIP: Unit for Visually Impaired People, Istituto Italiano di Tecnologia, Genoa, Italy.

Peripersonal space (PPS) is created by a multisensory interaction between different sensory modalities and can be modified by experience. In this article, we investigated whether an auditory training, inside the peripersonal space area, can modify the PPS around the head in sighted participants. The auditory training was based on echolocation. Read More

Auditory capture of visual apparent motion, both laterally and looming.

Acta Psychol (Amst) 2019 Feb 30;193:105-112. Epub 2018 Dec 30.

Department of Psychology, Arizona State University, United States of America.

Traditional tests of multisensory stimuli typically support that vision dominates spatial judgments and audition dominates temporal ones. Here, we examine if unambiguous auditory spatial cues can capture ambiguous visual ones in judgments of direction of apparent motion. The visual motion judgments include both lateral movement and movement in depth, each when coupled with auditory stimuli moving at one of four rates. Read More

Sensory representation of an auditory cued tactile stimulus in the posterior parietal cortex of the mouse.

Sci Rep 2018 05 17;8(1):7739. Epub 2018 May 17.

Brain Research Institute, University of Zurich, Zurich, Switzerland.

Sensory association cortices receive diverse inputs with their role in representing and integrating multi-sensory content remaining unclear. Here we examined the neuronal correlates of an auditory-tactile stimulus sequence in the posterior parietal cortex (PPC) using 2-photon calcium imaging in awake mice. We find that neuronal subpopulations in layer 2/3 of PPC reliably represent texture-touch events, in addition to auditory cues that presage the incoming tactile stimulus. Read More

Boat noise impacts risk assessment in a coral reef fish but effects depend on engine type.

Sci Rep 2018 03 1;8(1):3847. Epub 2018 Mar 1.

Biosciences, College of Life and Environmental Sciences, University of Exeter, Geoffrey Pope, Stocker Road, Exeter, EX4 4QD, UK.

Human noise pollution has increased markedly since the start of industrialization and there is international concern about how this may impact wildlife. Here we determined whether real motorboat noise affected the behavior, space use and escape response of a juvenile damselfish (Pomacentrus wardi) in the wild, and explored whether fish respond effectively to chemical and visual threats in the presence of two common types of motorboat noise. Noise from 30 hp 2-stroke outboard motors reduced boldness and activity of fish on habitat patches compared to ambient reef-sound controls. Read More

Assessing the influence of sound parameters on crossmodal cuing in different regions of space.

Acta Psychol (Amst) 2018 Apr 10;185:96-103. Epub 2018 Feb 10.

Crossmodal Research Laboratory, Department of Experimental Psychology, University of Oxford, Oxford, UK.

To date, crossmodal spatial cuing research has primarily investigated spatial attention modulated by the positioning of auditory cues, without addressing the question of the role played by sound parameters such as intensity change, waveform structure, or duration. Therefore in the present study, we investigated exogenous spatial cuing following the presentation of auditory cues having different intensity profiles (looming or receding), waveforms (triangular structured waveform or white noise), and durations (250 ms or 500 ms). Auditory cues were presented from one of four locations (front-left, front-right, rear-left, or rear-right). Read More

Mismatch negativity and psychophysical detection of rising and falling intensity sounds.

Biol Psychol 2018 03 5;133:99-111. Epub 2018 Feb 5.

I.P. Pavlov Institute of Physiology, Russian Academy of Sciences, Saint-Petersburg, Russia.

Human subjects demonstrate a perceptual priority for rising level sounds compared with falling level sounds. The aim of the present study was to investigate whether or not the perceptual preference for rising intensity can be found in the preattentive processing indexed by mismatch negativity (MMN). Reversed oddball stimulation was used to produce MMNs and to test the behavioral discrimination of rising, falling and constant level sounds. Read More

Asymmetries in behavioral and neural responses to spectral cues demonstrate the generality of auditory looming bias.

Proc Natl Acad Sci U S A 2017 09 21;114(36):9743-9748. Epub 2017 Aug 21.

Hearing Research Center, Boston University, Boston, MA 02215.

Studies of auditory looming bias have shown that sources increasing in intensity are more salient than sources decreasing in intensity. Researchers have argued that listeners are more sensitive to approaching sounds compared with receding sounds, reflecting an evolutionary pressure. However, these studies only manipulated overall sound intensity; therefore, it is unclear whether looming bias is truly a perceptual bias for changes in source distance, or only in sound intensity.

Judging time-to-passage of looming sounds: Evidence for the use of distance-based information.

PLoS One 2017 22;12(5):e0177734. Epub 2017 May 22.

Center for Computer Graphics, Guimarães, Portugal.

Perceptual judgments are an essential mechanism for our everyday interaction with other moving agents or events. For instance, estimation of the time remaining before an object contacts or passes us is essential to act upon or to avoid that object. Previous studies have demonstrated that participants use different cues to estimate the time to contact or the time to passage of approaching visual stimuli. Read More

Looming sounds are perceived as faster than receding sounds.

John G Neuhoff

Cogn Res Princ Implic 2016 14;1(1):15. Epub 2016 Nov 14.

Department of Psychology, The College of Wooster, Wooster, OH 44691 USA.

Each year thousands of people are killed by looming motor vehicles. Throughout our evolutionary history looming objects have posed a threat to survival and perceptual systems have evolved unique solutions to confront these environmental challenges. Vision provides an accurate representation of time-to-contact with a looming object and usually allows us to interact successfully with the object if required. Read More

Estimating the relative weights of visual and auditory tau versus heuristic-based cues for time-to-contact judgments in realistic, familiar scenes by older and younger adults.

Atten Percept Psychophys 2017 Apr;79(3):929-944

Institute of Psychology, Section Experimental Psychology, Johannes Gutenberg-Universität, 55099, Mainz, Germany.

Estimating time to contact (TTC) involves multiple sensory systems, including vision and audition. Previous findings suggested that the ratio of an object's instantaneous optical size/sound intensity to its instantaneous rate of change in optical size/sound intensity (τ) drives TTC judgments. Other evidence has shown that heuristic-based cues are used, including final optical size or final sound pressure level. Read More

A "looming bias" in spatial hearing? Effects of acoustic intensity and spectrum on categorical sound source localization.

Atten Percept Psychophys 2017 Jan;79(1):352-362

The MARCS Institute for Brain, Behaviour and Development, Western Sydney University, Locked Bag 1797, Penrith, NSW, 2751, Australia.

Continuous increases of acoustic intensity (up-ramps) can indicate a looming (approaching) sound source in the environment, whereas continuous decreases of intensity (down-ramps) can indicate a receding sound source. From psychoacoustic experiments, an "adaptive perceptual bias" for up-ramp looming tonal stimuli has been proposed (Neuhoff, 1998). This theory postulates that (1) up-ramps are perceptually salient because of their association with looming and potentially threatening stimuli in the environment; (2) tonal stimuli are perceptually salient because of an association with single and potentially threatening biological sound sources in the environment, relative to white noise, which is more likely to arise from dispersed signals and nonthreatening/nonbiological sources (wind/ocean).

Anthropogenic (man-made) noise, a global pollutant of international concern, is known to affect the physiology and behaviour of a range of organisms. However, experimental studies have tended to focus on trait means; intra-population variation in responses are likely, but have rarely been explored. Here we use established experimental methods to demonstrate a condition-dependent effect of additional noise. Read More

Intertrial Variability in the Premotor Cortex Accounts for Individual Differences in Peripersonal Space.

J Neurosci 2015 Dec;35(50):16328-39

Institute of Mental Health Research, University of Ottawa, Ottawa, Ontario K1Z 7K4, Canada, and.

Unlabelled: We live in a dynamic environment, constantly confronted with approaching objects that we may either avoid or be forced to address. A multisensory and sensorimotor interface, the peripersonal space (PPS), mediates every physical interaction between our body and the environment. Behavioral investigations show high variability in the extension of PPS across individuals, but there is a lack of evidence on the neural underpinnings of these large individual differences.

Pile-Driving Noise Impairs Antipredator Behavior of the European Sea Bass Dicentrarchus labrax.

Adv Exp Med Biol 2016 ;875:273-9

Biosciences, College of Life and Environmental Sciences, University of Exeter, Exeter, EX4 4QD, UK.

In an increasingly industrialized world, man-made noise is changing the underwater acoustic environment. The effects of anthropogenic noise on marine ecosystems are not yet fully understood despite important implications for science and policy, in particular with respect to investment in offshore renewable energy. In this study, a traditional looming-stimulus experimental setup was used to investigate the acute effects of pile-driving noise on the antipredator response of European sea bass (Dicentrarchus labrax).

University of Liverpool, Department of Psychological Sciences, Eleanor Rathbone Building, L69 7ZA, UK. Electronic address:

Motion is represented by low-level signals, such as size-expansion in vision or loudness changes in the auditory modality. The visual and auditory signals from the same object or event may be integrated and facilitate detection. We explored behavioural and electrophysiological correlates of congruent and incongruent audio-visual depth motion in conditions where auditory level changes, visual expansion, and visual disparity cues were manipulated.

Dementias show differential physiological responses to salient sounds.

Front Behav Neurosci 2015 24;9:73. Epub 2015 Mar 24.

Dementia Research Centre, UCL Institute of Neurology, University College London London, UK.

Abnormal responsiveness to salient sensory signals is often a prominent feature of dementia diseases, particularly the frontotemporal lobar degenerations, but has been little studied. Here we assessed processing of one important class of salient signals, looming sounds, in canonical dementia syndromes. We manipulated tones using intensity cues to create percepts of salient approaching ("looming") or less salient withdrawing sounds. Read More
