    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
