    • Affect of the unconscious: Visually suppressed angry faces modulate our decisions 

      Almeida, Jorge; Pajtas, Petra E.; Mahon, Bradford Z.; Nakayama, Ken; Caramazza, Alfonso (Springer Nature, 2012)
      Emotional and affective processing imposes itself over cognitive processes and modulates our perception of the surrounding environment. In two experiments, we addressed the issue of whether nonconscious processing of affect ...

    • Capturing Specific Abilities as a Window into Human Individuality: The Example of Face Recognition 

      Wilmer, Jeremy Bennet; Germine, Laura Thi; Chabris, Christopher; Chatterjee, Garga; Gerbasi, Margaret E; Nakayama, Ken (Taylor & Francis, 2012)
      Proper characterization of each individual's unique pattern of strengths and weaknesses requires good measures of diverse abilities. Here, we advocate combining our growing understanding of neural and cognitive mechanisms ...

    • The Development of Character Judgments From Faces 

      Cogsdill, Emily (2015-03-30)
      First impressions play a central role in human social interaction. In particular, the face is a rich source of information that perceivers use in making both initial and lasting character judgments. Despite the large and ...

    • Dissociations of Face and Object Recognition in Developmental Prosopagnosia 

      Duchaine, Brad; Nakayama, Ken (Massachusetts Institute of Technology Press, 2005)
      Neuropsychological studies with patients suffering from prosopagnosia have provided the main evidence for the hypothesis that the recognition of faces and objects rely on distinct mechanisms. Yet doubts remain, and it has ...

    • Engaging the Motor System with Masked Orthographic Primes: A Kinematic Analysis 

      Finkbeiner, Matthew; Song, Joo-Hyun; Nakayama, Ken; Caramazza, Alfonso (Taylor & Francis, 2008)
      We report two experiments in which participants categorized target words (e. g., BLOOD or CUCUMBER) according to their canonical colour of red or green by pointing to a red square on the left or a green square on the right. ...

    • Experiencing and perceiving visual surfaces 

      Nakayama, Ken; Shimojo, Shinsuke (American Association for the Advancement of Science (AAAS), 1992)
      A theoretical framework is proposed to understand binocular visual surface perception based on the idea of a mobile observer sampling images from random vantage points in space. Application of the generic sampling principle ...

    • Face recognition: a model specific ability 

      Wilmer, Jeremy B.; Germine, Laura T.; Nakayama, Ken (Frontiers Media S.A., 2014)
      In our everyday lives, we view it as a matter of course that different people are good at different things. It can be surprising, in this context, to learn that most of what is known about cognitive ability variation across ...

    • Fitting the Mind to the World: Face Adaptation and Attractiveness Aftereffects 

      Rhodes, Gillian; Jeffery, Linda; Watson, Tamara L.; Clifford, Colin W. G.; Nakayama, Ken (Blackwell Publishers, 2003)
      Average faces are attractive, but what is average depends on experience. We examined the effect of brief exposure to consistent facial distortions on what looks normal (average) and what looks attractive. Adaptation to a ...

    • High-level neural structures constrain visual behavior 

      Cohen, Michael A (2014-06-06)
      Visual cognition is notoriously limited: only a finite amount of information can be fully processed at a given instant. What is the source of these limitations? Here, we suggest that the organization of higher-level visual ...

    • Human Wagering Behavior Depends on Opponents' Faces 

      Schlicht, Erik J.; Shimojo, Shinsuke; Camerer, Colin F.; Battaglia, Peter; Nakayama, Ken (Public Library of Science, 2010)
      Research in competitive games has exclusively focused on how opponent models are developed through previous outcomes and how peoples' decisions relate to normative predictions. Little is known about how rapid impressions ...

    • Natural-Scene Perception Requires Attention 

      Cohen, Michael A.; Alvarez, George; Nakayama, Ken (SAGE Publications, 2011-08-12)
      Is visual attention required for visual consciousness? In the past decade, many have claimed that awareness can arise in the absence of attention. This claim is largely based on the notion that natural scene (or "gist") ...

    • No Global Processing Deficit in the Navon Task in 14 Developmental Prosopagnosics 

      Duchaine, Bradley; Yovel, Galit; Nakayama, Ken (Oxford University Press, 2007)
      Faces are represented in a more configural or holistic manner than other objects. Substantial evidence indicates that this representation results from face-specific mechanisms, but some have argued that it is produced by ...

    • Numeric Comparison in a Visually-guided Manual Reaching Task 

      Song, Joo-Hyun; Nakayama, Ken (Elsevier, 2008)
      Nearly all studies on perception and cognition have used discrete responses to infer internal cognitive processes. In the current study, we demonstrate that visually-guided manual reaching can provide new opportunities to ...

    • Perceptual Annotation: Measuring Human Vision to Improve Computer Vision 

      Scheirer, Walter Jerome; Anthony, Samuel English; Nakayama, Ken; Cox, David Daniel (Institute of Electrical & Electronics Engineers (IEEE), 2014)
      For many problems in computer vision, human learners are considerably better than machines. Humans possess highly accurate internal recognition and learning mechanisms that are not yet understood, and they frequently have ...

    • Processing Multiple Visual Objects Is Limited by Overlap in Neural Channels 

      Cohen, Michael A.; Konkle, Talia; Rhee, Juliana Y.; Nakayama, Ken; Alvarez, George (Proceedings of the National Academy of Sciences, 2014-06-02)
      High-level visual categories (e.g., faces, bodies, scenes, and objects) have separable neural representations across the visual cortex. Here, we show that this division of neural resources affects the ability to simultaneously ...

    • Super-recognizers: People with Extraordinary Face Recognition Ability 

      Russell, Richard; Duchaine, Brad; Nakayama, Ken (Psychonomic Society, 2009)
      We tested 4 people who claimed to have significantly better than ordinary face recognition ability. Exceptional ability was confirmed in each case. On two very different tests of face recognition, all 4 experimental subjects ...

    • Temporal Processing in the Visual System 

      Aghdaee, Seyed Mehdi (2013-03-18)
      Encoding time is one of the most important features of the mammalian brain. The visual system, comprising almost half of the brain is of no exception. Time processing enables us to make goal-directed behavior in the optimum ...

    • Tracking the allocation of attention using human pupillary oscillations 

      Naber, Marnix; Alvarez, George A.; Nakayama, Ken (Frontiers Media S.A., 2013)
      The muscles that control the pupil are richly innervated by the autonomic nervous system. While there are central pathways that drive pupil dilations in relation to arousal, there is no anatomical evidence that cortical ...

    • Unconscious Processing Dissociates along Categorical Lines 

      Almeida, Jorge Manuel; Mahon, B. Z.; Nakayama, Ken; Caramazza, Alfonso (National Academy of Sciences, 2008)
      Visual object recognition is subserved by ventral temporal and occipital regions of the brain. Regions comprising the dorsal visual pathway have not been considered relevant for object recognition, despite strong categorical ...

    • Visual Awareness Is Limited by the Representational Architecture of the Visual System 

      Cohen, Michael A; Nakayama, Ken; Konkle, Talia A; Stantić, Mirta; Alvarez, George Angelo (MIT Press - Journals, 2015)
      Visual perception and awareness have strict limitations. We suggest that one source of these limitations is the representational architecture of the visual system. Under this view, the extent to which items activate the ...
