    • Bringing in the Experts: How Team Composition and Collaborative Planning Jointly Shape Analytic Effectiveness 

      Woolley, Anita Williams; Gerbasi, Margaret E.; Chabris, Christopher; Kosslyn, Stephen; Hackman, J. Richard (Sage Periodicals Press, 2008)
      This study investigates the separate and joint effects of the inclusion of experts and collaborative planning on the performance of analytic teams. Teams either did or did not include members with expert-level task-relevant ...
    • Crime Alert! How Thinking about a Single Suspect Automatically Shifts Stereotypes toward an Entire Group 

      Akalis, Scott; Banaji, Mahzarin; Kosslyn, Stephen (Cambridge University Press, 2008)
      Crime alerts are meant to raise community awareness and identify individual criminal suspects; they are not expected to affect attitudes and beliefs toward the social group to which an individual suspect belongs. However, ...
    • Dissociation Between Visual Attention and Visual Mental Imagery 

      Thompson, William L.; Hsiao, Yaling; Kosslyn, Stephen Michael (Taylor & Francis, 2010-10-27)
      Visual mental imagery (which involves generating and transforming visual mental representations, i.e., seeing with the mind's eye) and visual attention appear to be distinct processes. However, some researchers have claimed ...
    • Fear Selectively Modulates Visual Mental Imagery and Visual Perception 

      Borst, Grégoire; Kosslyn, Stephen Michael (Taylor & Francis, 2010)
      Emotions have been shown to modulate low-level visual processing of simple stimuli. In this study, we investigate whether emotions only modulate processing of visual representations created from direct visual inputs or ...
    • Imagining Predictions: Mental Imagery as Mental Emulation 

      Moulton, Samuel; Kosslyn, Stephen (The Royal Society, 2009)
      We argue that the primary function of mental imagery is to allow us to generate specific predictions based upon past experience. All imagery allows us to answer 'what if ' questions by making explicit and accessible the ...
    • Individual Differences in Cerebral Blood Flow in Area 17 Predict the Time to Evaluate Visualized Letters 

      Kosslyn, Stephen Michael; Thompson, William L.; Kim, Irene J.; Rauch, Scott Laurence; Alpert, Nathaniel Moritz (Massachusetts Institute of Technology Press, 1996)
      Sixteen subjects closed their eyes and visualized uppercase letters of the alphabet at two sizes, as small as possible or as large as possible while remaining “visible.” Subjects evaluated a shape characteristic of each ...
    • Inspecting Visual Mental Images: Can People "See" Implicit Properties as Easily in Imagery and Perception? 

      Thompson, William; Kosslyn, Stephen; Hoffman, Michael S.; van der Kooij, Katinka (Psychonomic Society, 2008)
      Can people "see" previously unnoticed properties in objects that they visualize, or are they locked into the organization of the pattern that was encoded during perception? To answer this question, we first asked a group ...
    • Is Cognitive Neuropsychology Plausible? The Perils of Sitting on a One-Legged Stool 

      Kosslyn, Stephen Michael; Intriligator, James M. (Massachusetts Institute of Technology Press, 1992)
      We distinguish between strong and weak cognitive neuropsychology, with the former attempting to provide direct insights into the nature of information processing and the latter having the more modest goal of providing ...
    • Mental Rotation is Not Easily Cognitively Penetrable 

      Borst, Grégoire; Kievit, Rogier A.; Thompson, William L.; Kosslyn, Stephen Michael (Taylor & Francis, 2010-10-13)
      When participants take part in mental imagery experiments, are they using their "tacit knowledge" of perception to mimic what they believe should occur in the corresponding perceptual task? Two experiments were conducted ...
    • Neural processes underlying self- and other-related lies: An individual difference approach using fMRI 

      Ganis, Giorgio; Morris, Robert; Kosslyn, Stephen Michael (Informa UK Limited, 2009)
      Two hypotheses were tested using a novel individual differences approach, which identifies rate-limiting brain regions, that is, brain regions in which variations in neural activity predict variations in behavioral performance. ...
    • On Cognitive Neuroscience 

      Kosslyn, Stephen Michael (Massachusetts Institute of Technology Press, 1994)
      Stephen M. Kosslyn is Professor of Psychology at Harvard University and an Associate Psychologist in the Department of Neurology at the Massachusetts General Hospital. He received his B.A. in 1970 from UCLA and his Ph.D. ...
    • Performance on Middle School Geometry Problems with Geometry Clues Matched to Three Different Cognitive Styles 

      Anderson, Karen L.; Casey, M. Beth; Thompson, William; Burrage, Marie S.; Pezaris, Elizabeth; Kosslyn, Stephen (Blackwell Publishing, 2008)
      This study investigated the relationship between 3 ability-based cognitive styles (verbal deductive, spatial imagery, and object imagery) and performance on geometry problems that provided different types of clues. The ...
    • Receptive Field Characteristics That Allow Parietal Lobe Neurons to Encode Spatial Properties of Visual Input: A Computational Analysis 

      O'Reilly, Randall C.; Kosslyn, Stephen Michael; Marsolek, Chad J.; Chabris, Christopher F (Massachusetts Institute of Technology Press, 1990)
      A subset of visually sensitive neurons in the parietal lobe apparently can encode the locations of stimuli, whereas visually sensitive neurons in the inferotemporal cortex (area IT) cannot. This finding is puzzling because ...
    • Training Generalized Spatial Skills 

      Wright, Rebecca; Thompson, William; Ganis, Giorgio; Newcombe, Nora S.; Kosslyn, Stephen (Psychonomic Society, 2008)
      Spatial transformation skills are an essential aspect of cognitive ability. These skills can be improved by practice, but such improvement has usually been specific to tasks and stimuli. The present study investigated ...
    • Transient Activity in the Human Calcarine Cortex During Visual-Mental Imagery: An Event-Related fMRI Study 

      Klein, Isabelle; Paradis, Anne-Lise; Poline, Jean-Baptiste; Kosslyn, Stephen Michael; Bihan, Denis Le (Massachusetts Institute of Technology Press, 2000)
      Although it is largely accepted that visual-mental imagery and perception draw on many of the same neural structures, the existence and nature of neural processing in the primary visual cortex (or area V1) during visual ...
    • Two Forms of Spatial Imagery: Neuroimaging Evidence ​ 

      Thompson, William L.; Slotnick, Scott D.; Burrage, Marie S.; Kosslyn, Stephen Michael (SAGE Publications, 2009)
      Spatial imagery may be useful in such tasks as interpreting graphs and solving geometry problems, and even in performing surgery. This study provides evidence that spatial imagery is not a single faculty; rather, visualizing ...
    • Types of deception revealed by individual differences in cognitive abilities 

      Morgan, Charity J.; LeSage, Julia B.; Kosslyn, Stephen Michael (Informa UK Limited, 2009)
      The two studies reported in this article are an extension of the neuroimaging study by Ganis et al. (2003), which provided evidence that different types of lies arise from different cognitive processes. We examined the ...
    • Using Neuroimaging to Resolve the Psi Debate 

      Moulton, Samuel; Kosslyn, Stephen (MIT Press, 2008)
      Parapsychology is the scientific investigation of apparently paranormal mental phenomena (such as telepathy, i.e., "mind reading"), also known as psi. Despite widespread public belief in such phenomena and over 75 years ...
    • Visual Mental Imagery Activates Topographically Organized Visual Cortex: PET Investigations 

      Kosslyn, Stephen Michael; Alpert, Nathaniel Moritz; Thompson, William L.; Maljkovic, Vera; Weise, Steven B.; Chabris, Christopher F; Hamilton, Sania E.; Rauch, Scott Laurence; Buonanno, Ferdinando Stelio (Massachusetts Institute of Technology Press, 1993)
      Cerebral blood flow was measured using positron emission tomography (PET) in three experiments while subjects performed mental imagery or analogous perceptual tasks. In Experiment 1, the subjects either visualized letters ...
    • Visual Mental Imagery and Visual Perception: Structural Equivalence Revealed by Scanning Processes 

      Borst, Gregoire; Kosslyn, Stephen (Psychonomic Society, 2008)
      The research reported in the present article investigates whether information is represented the same way in both visual mental imagery and the early phases of visual perception. In Experiment 1, the same participants ...
