A persistent belief holds that humans can imagine visual content but not odors. While imagery is regarded as recreating a perceptual representation, it unknown whether olfactory mental shares format. Visual studies have demonstrated this formatting using distance and shape similarity judgments, whereas often use single-odor vividness ratings, complicating the establishment of for Using odor pair scores from two experiments (odor-based: 8,880 ratings 37 participants, including 20 women;...
Personal space regulation ensures the maintenance of a margin safety between individual and surrounding world. However, little is known about specific neural mechanisms implicated in regulating distance from conspecifics versus non-social stimuli. Here, we investigated correlates personal intrusions by social Thirty volunteers underwent fMRI scanning while viewing approaching or withdrawing faces (Social) insects/arachnids (Non-social). Preferred to stimuli was assessed behaviourally...
Abstract Prior laboratory research has suggested that humans may become more prosocial in stressful or threatening situations, but it is unknown whether the link between prosociality and defense generalizes to real-life. Here, we examined association defensive responses a real-world threat (the COVID-19 pandemic) everyday altruism. Four independent samples of 150 (N = 600) US residents were recruited online at 4 different timepoints, self-report measures perceived threat, emotions (e.g.,...
Threatening situations have been shown to influence prosocial and altruistic behaviour in laboratory studies. However, it is unknown whether those effects would transfer a real-life crisis like the COVID-19 pandemic. In this study, we examined impact of changing threat on everyday altruism. Specifically, investigated association between defensive emotions associated with varying levels perceived imminence, reported frequency behaviours. A sample 600 United States residents was recruited...
Specific phobia can be treated successfully with exposure therapy. Although therapy has strong effects on self-reported ratings and behavioral avoidance, measures derived from electroencephalography (EEG) are scant unclear. To fill this gap, spider-phobic individuals received either in-vivo or virtual reality treatment. Patients were tested twice (one week before after treatment), control subjects once. In each session, EEG was recorded to spider pictures as well other positive, negative,...
Abstract Odor identification is a common assessment of olfaction, and it affected in large number diseases. Identification abilities decline with age, but little known about whether there are perceptual odor features that can be used to predict identification. Here, we analyzed data from large, population-based sample 2,479 adults, aged 60 years or above, the Swedish National study on Aging Care Kungsholmen. Participants performed both free cued tests. In separate experiment, assessed...
Creating and evaluating predictions are considered important features in sensory perception. Little is known about processing differences between the senses their cortical substrates. Here, we tested hypothesis that olfaction, sense of smell, would be highly dependent on (nonolfactory) object-predictive cues involve distinct features. We developed a novel paradigm to compare prediction error across senses. Participants listened spoken word (e.g., "lilac") determined whether target stimuli...
Identifying objects in the environment is one of most important features our senses. Toward this goal, predictions are made from known environmental regularities. It unknown whether different sensory systems may rely differently on cues for prediction and evaluation. Olfaction, sense smell, provides a means to test hypothesis. People often unable identify odor stimuli based scent alone, vision audition needed. We tested olfactory (relative visual) identification especially dependent...
Although our understanding of human olfactory perception has increased dramatically, it remains less well understood how olfaction interacts with cognitive processes. In this overview, we review the claim that evolved to predominantly embody “novelty detection”, a framework leaves little room for representations and We challenge by pointing several perceived limitations. Instead, argue is best in terms its reliance on top-down processes; visual or verbal contexts may generate predictions...
