  • Animals Do Not Induce or Reduce Attentional Blinking, But They Are Reported More Accurately in a Rapid Serial Visual Presentation Task 
    Hagen, Thomas; Laeng, Bruno (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Evolutionary psychologists have suggested that modern humans have evolved to automatically direct their attention toward animal stimuli. Although this suggestion has found support in several attentional paradigms, it is ...

    The ability to perceive the beat in music is crucial for both music listeners and players with expert musicians being notably skilled at noticing fine deviations in the beat. However, it is unclear whether this beat ...
  • Caressed by music: Related preferences for velocity of touch and tempo of music? 
    Sailer, Uta; Zucknick, Manuela Karola; Laeng, Bruno (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Given that both hearing and touch are ‘mechanical senses’ that respond to physical pressure or mechanical energy and that individuals appear to have a characteristic internal or spontaneous tempo, individual preferences ...
  • The Change Detection Advantage for Animals: An Effect of Ancestral Priorities or Progeny of Experimental Design? 
    Hagen, Thomas; Laeng, Bruno (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    The “animate monitoring” hypothesis proposes that humans are evolutionarily predisposed to recruit attention toward animals. Support for this has repeatedly been obtained through the change detection paradigm where animals ...
  • Chasing Animals With Split Attention: Are Animals Prioritized in Visual Tracking? 
    Hagen, Thomas; Espeseth, Thomas; Laeng, Bruno (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Some evolutionary psychologists have hypothesized that animals have priority in human attention. That is, they should be detected and selected more efficiently than other types of objects, especially man-made ones. Such a ...
  • Classifiers in non-European languages and semantic impairments in western neurological patients have a common cognitive structure 
    Lobben, Marit; Agata, Bochynska; Tanggaard, Stine; Laeng, Bruno (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    We compared two non-overlapping data sets: (a) the semantic categories in representative samples of nominal classification languages (N = 334); and in a non-overlapping population (b) semantic category-specific impairments ...
  • Colorful glares: Effects of colors on brightness illusions measured with pupillometry 
    Suzuki, Yuta; Minami, Tetsuto; Laeng, Bruno; Nakauchi, Shigeki (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    We hypothesized that pupil constrictions to the glare illusion, where converging luminance gradients subjectively enhance the perception of brightness, would be stronger for ‘blue’ than for other colors. Such an expectation ...
  • Cueing the Necker cube: Pupil dilation reflects the viewing-from-above constraint in bistable perception. 
    Sato, Fumiaki; Laeng, Bruno; Nakauchi, Shigeki; Minami, Tetsuto (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    We hypothesized that a perceptually ambiguous or bistable object (Necker cube) can be more effectively biased to assume a point of view-from-above (VFA) than from below the object by cueing attention. Participants viewed ...
  • Detecting implicit and explicit facial emotions at different ages 
    Prete, Giulia; Ceccato, Irene; Bartolini, Emanuela; Di Crosta, Adolfo; La Malva, Pasquale; Palumbo, Rocco; Laeng, Bruno; Tommasi, Luca; Mammarella, Nicola; Di Domenico, Alberto (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Abstract Emotions are processed in the brain through a cortical route, responsible for detailed-conscious recognition and mainly based on image High Spatial Frequencies (HSF), and a subcortical route, responsible for ...
  • Does stereopsis improve face identification? A study using a virtual reality display with integrated eye-tracking and pupillometry 
    Liu, Hang; Laeng, Bruno; Czajkowski, Nikolai (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Stereopsis is a powerful depth cue for humans, which may also contribute to object recognition. In particular, we surmise that face identification would benefit from the availability of stereoscopic depth cues, since facial ...
  • The effects of cognitive abilities and task demands on tonic and phasic pupil sizes 
    Aminihajibashi, Samira; Hagen, Thomas; Andreassen, Ole Andreas; Laeng, Bruno; Espeseth, Thomas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Previous studies on individual differences in pupil size of healthy individuals and their relation to performance have been inconclusive. Using a novel approach, we tested the effect of general cognitive abilities and level ...
  • Environmental risks to humans, the first database of valence and arousal ratings for images of natural hazards 
    Prete, Giulia; Laeng, Bruno; Tommasi, Luca (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Due to their relevance for the entire society, environmental hazards have largely been investigated in terms of their psychological effects. However, a complete image database comprising different categories of catastrophes ...
  • Eye and hand motor interactions with the Symbol Digit Modalities Test in early multiple sclerosis 
    Nygaard, Gro O.; de Rodez Benavent, Sigrid Aune; Harbo, Hanne Flinstad; Laeng, Bruno; Sowa, Piotr; Damangir, Soheil; Nilsen, Kristian Bernhard; Etholm, Lars; Tønnesen, Siren; Kerty, Emilia; Drolsum, Liv; Landrø, Nils Inge; Celius, Elisabeth Gulowsen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Purpose Eye and hand motor dysfunction may be present early in the disease course of relapsing-remitting multiple sclerosis (RRMS), and can affect the results on visual and written cognitive tests. We aimed to test for ...
  • The Eye Pupil’s Response to Static and Dynamic Illusions of Luminosity and Darkness 
    Zavagno, Damiele; Tommasi, Luca; Laeng, Bruno (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Pupil diameters were recorded with an eye-tracker while participants observed cruciform patterns of gray-scale gradients that evoked illusions of enhanced brightness (glare) or of enhanced darkness. The illusions were ...
  • The "face race lightness illusion": An effect of the eyes and pupils? 
    Laeng, Bruno; Kiambarua, Kenneth Gitiye; Hagen, Thomas; Bochynska, Agata; Lubell, James; Suzuki, Hikaru; Okubo, Matia (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
