  • Effect of contiguity and figure-ground organization on the area rule of lightness 

    Boyaci, H.; Simsek, K.; Subasi, E. (Association for Research in Vision and Ophthalmology, 2014)
    In a simple two-dimensional (2D) display composed of two uniform surfaces with different luminances, the lightness of the darker surface varies as a function of its relative area while its luminance is held constant ...
  • Attention-Dependent Representation of a Size Illusion in Human V1 

    Fang, F.; Boyaci, H.; Kersten, D.; Murray, S. O. (Elsevier, 2008-11-11)
    One of the most fundamental properties of human primary visual cortex (V1) is its retinotopic organization, which makes it an ideal candidate for encoding spatial properties, such as size, of objects. However, three-dimensional ...
  • Detection and localization of specular surfaces using image motion cues 

    Yilmaz, O.; Doerschner, K. (Springer Berlin Heidelberg, 2014)
    Successful identification of specularities in an image can be crucial for an artificial vision system when extracting the semantic content of an image or while interacting with the environment. We developed an algorithm ...
  • Effects of surface reflectance and 3D shape on perceived rotation axis 

    Doerschner, K.; Yilmaz, O.; Kucukoglu, G.; Fleming, R. W. (Association for Research in Vision and Ophthalmology, 2013-09)
    Surface specularity distorts the optic flow generated by a moving object in a way that provides important cues for identifying surface material properties (Doerschner, Fleming et al., 2011). Here we show that specular flow ...
  • Attention modulates neuronal correlates of interhemispheric integration and global motion perception 

    Akin, B.; Ozdem, C.; Eroglu, S.; Taslak Keskin, D.; Fang, F.; Doerschner, K.; Kersten, D.; Boyaci, H. (Association for Research in Vision and Ophthalmology, 2014-10)
    In early retinotopic areas of the human visual system, information from the left and right visual hemifields (VHFs) is processed contralaterally in two hemispheres. Despite this segregation, we have the perceptual experience ...
  • Adolescent risk-taking as a function of prenatal cocaine exposure and biological sex 

    Allen, J. W. P.; Bennett, D. S.; Carmody, D. P.; Wang, Y.; Lewis, M. (Elsevier, 2014)
    Objective: To examine the effects of prenatal cocaine exposure and biological sex on adolescent risk-taking while controlling for early environmental risk. Methods: Adolescents (n. = 114, mean age. = 16) were grouped ...
  • Growth Hormone and Insulin-Like Growth Factor-I alter Hippocampal Excitatory Synaptic Transmission in Young and Old Rats 

    Molina, D. P.; Ariwodola, O. J.; Weiner, J. L.; Brunso Bechtold, J. K.; Adams, M. M. (Springer Netherlands, 2013)
    In rats, as in humans, normal aging is characterized by a decline in hippocampal-dependent learning and memory, as well as in glutamatergic function. Both growth hormone (GH) and insulin-like growth factor-I (IGF-I) levels ...
  • Retinotopic sensitisation to spatial scale: Evidence for flexible spatial frequency processing in scene perception 

    Ozgen, E.; Payne, H. E.; Sowden, P. T.; Schyns, P. G. (Elsevier, 2006-03)
    Observers can use spatial scale information flexibly depending on categorisation task and on their prior sensitisation. Here, we explore whether attentional modulation of spatial frequency processing at early stages of ...
  • Shovels and Swords: How realistic and fantastical themes affect children's word learning 

    Weisberg, D. S.; Ilgaz, H.; Hirsh Pasek, K.; Golinkoff, R. M.; Nicolopoulou, A.; Dickinson, D. (Elsevier, 2015)
    Research has shown that storybooks and play sessions help preschool children learn vocabulary, thereby benefiting their language and school readiness skills. But the kind of content that leads to optimal vocabulary learning ...
  • Rapid Classificationof Specular and Diffuse Reflection from Image Velocities 

    Doerschner, K.; Kersten, D.; Schrater, P. (Elsevier, 2011-09)
    We propose a method for rapidly classifying surface reflectance directly from the output of spatiotemporal filters applied to an image sequence of rotating objects. Using image data from only a single frame, we compute ...
  • Evolved individual differences: Advancing a condition-dependent model of personality 

    Lewis, D. M. G. (Elsevier, 2015-10)
    The field of personality psychology offers a wealth of robust empirical research and a successful descriptive taxonomy, but neither explains the origins of the structure of human personality nor elaborates a generative ...
  • Visual Motion and the Perception of Surface Material 

    Doerschner, K.; Fleming, R.; Yilmaz, O.; Schrater, P.; Hartung, B.; Kersten, D. (Elsevier, 2011-12-06)
    Many critical perceptual judgments, from telling whether fruit is ripe to determining whether the ground is slippery, involve estimating the material properties of surfaces. Very little is known about how the brain recognizes ...
  • The impact of regime-type on health: does redistribution explain everything? 

    Wigley, S.; Akkoyunlu Wigley, A. (Cambridge University Press, 2011-09-22)
    Many scholars claim that democracy improves population health. The prevailing explanation for this is that democratic regimes distribute health-promoting resources more widely than autocratic regimes. The central contention ...
  • Novel object recognition is not affected by age despite age-related brain changes 

    Aktoprak, I.; Dinc, P.; Gunay, G.; Adams, M. M. (Scientific Research Publishing, 2013)
    Age-related memory impairments show a progressive decline across lifespan. Studies have demonstrated equivocal results in biological and behavioral outcomes of aging. Thus, in the present study we examined the novel object ...
  • Growth hormone modulates hippocampal excitatory synaptic transmission and plasticity in old rats 

    Molina, D. P.; Ariwodola, O. J.; Linville, C.; Sonntag, W. E.; Weiner, J. L.; Brunso Bechtold, J. K.; Adams, M. M. (Elsevier, 2012-09)
    Alterations in the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptor (AMPA-R) and N-methyl-D-aspartate receptor (NMDA-R) have been documented in aged animals and may contribute to changes in hippocampal-dependent ...
  • Mating Strategy, disgust and food neophobia 

    Al Shawaf, L.; Lewis, D. M. G.; Alley, T. R.; Buss, D. M. (Elsevier, 2015-02-01)
    Food neophobia and disgust are commonly thought to be linked, but this hypothesis is typically implicitly assumed rather than directly tested. Evidence for the connection has been based on conceptually and empirically ...
  • Ethnic Identity and discrimination among children 

    Friesen, J.; Arifovic, J.; Wright, S. C.; Ludwig, A.; Giamo, L.; Baray, G. (Elsevier, 2012-12)
    We engaged over 430 Canadian children in a series of activities designed to reveal their evaluations of three ethnic groups (White, East Asian and South Asian), their identification with these groups, and their behavior ...
  • Gene Expression changes in aging zebrafish (Danio rerio) brains are sexually dimorphic 

    Arslan Ergul, A.; Adams, M. M. (BioMed Central, 2014)
    Background: Brain aging is a multi-factorial process due to both genetic and environmental factors. The zebrafish has recently become a popular model organism for examining aging and age-related diseases because as ...
  • The Openness-Calibration Hypothesis 

    Lewis, D. M. G.; Al Shawaf, L.; Yilmaz, C. (Elsevier, 2015-07)
    The current study tested the hypotheses that (1) psychological adaptations calibrate Openness to Experience to facilitate or deter pursuit of short-term mating, and (2) this calibration varies as a function of mating ...
  • Relative flattening between velvet and matte 3D shapes: Evidence for similar shape-from-shading computations 

    Wijntjes, M. W. A.; Doerschner, K.; Kucukoglu, G.; Pont, S. C. (Association for Research in Vision and Ophthalmology, 2012)
    Among other cues, the visual system uses shading to infer the 3D shape of objects. The shading pattern depends on the illumination and reflectance properties (BRDF). In this study, we compared 3D shape perception between ...
