  1. pmc Seeing and hearing a word: combining eye and ear is more efficient than combining the parts of a word
    Matthieu Dubois
    Psychology and Neural Science, New York University, New York, New York, USA
    PLoS ONE 8:e64803. 2013
    ..The brain's machinery optimally combines only cues that are perceived as originating from the same object. Presumably such cues each find their own way through the brain to arrive at the same object representation...
  2. pmc Measuring contrast sensitivity
    Denis G Pelli
    Psychology Department and Center for Neural Science, New York University, USA
    Vision Res 90:10-4. 2013
    ..Having many alternatives reduces the guessing rate, which makes each trial more informative, so fewer trials are needed. Finally, populations who may experience crowding or target confusion should be tested with one target at a time. ..
  3. doi request reprint Object recognition: visual crowding from a distance
    Denis G Pelli
    Psychology Department and Center for Neural Science, New York University, New York, New York, USA
    Curr Biol 23:R478-9. 2013
    ..This new finding, from a recent study, shows that the brain's remapping for the anticipated eye movement unavoidably combines features from the target's current and future retinal locations into one perceptual object...
  4. pmc Theories of reading should predict reading speed
    Denis G Pelli
    Department of Psychology and Center for Neural Science, New York University, New York, NY 10003
    Behav Brain Sci 35:297-8. 2012
    ..Reading speed matters in most real-world contexts, and it is a robust and easy aspect of reading to measure. Theories of reading should account for speed...
  5. pmc Grouping in object recognition: the role of a Gestalt law in letter identification
    Denis G Pelli
    Psychology and Neural Science, New York University, New York, NY 10003, USA mail
    Cogn Neuropsychol 26:36-49. 2009
    ..This shows that letter identification obeys the Gestalt law of good continuation and may be the first confirmation of the original Gestalt claim that object recognition involves grouping...
  6. pmc Crowding: a cortical constraint on object recognition
    Denis G Pelli
    Psychology and Neural Science, New York University, New York, NY 10003, USA
    Curr Opin Neurobiol 18:445-51. 2008
    ..Furthermore, we show that much of this can be accounted for by supposing that each 'combining field', defined by the critical spacing measurements, is implemented by a fixed number of cortical neurons...
  7. pmc The uncrowded window of object recognition
    Denis G Pelli
    Department of Psychology and Center for Neural Science, New York University, 6 Washington Place, New York, New York 10003, USA
    Nat Neurosci 11:1129-35. 2008
    ..The region where object spacing exceeds critical spacing is the 'uncrowded window'. Observers cannot recognize objects outside of this window and its size limits the speed of reading and search...
  8. doi request reprint Crowding and eccentricity determine reading rate
    Denis G Pelli
    Psychology and Neural Science, New York University, New York, NY, USA
    J Vis 7:20.1-36. 2007
    ..In all conditions tested--all sizes and spacings, central and peripheral, ordered and scrambled--reading is limited by crowding. For each observer, at each vertical eccentricity, reading rate is proportional to the uncrowded span...
  9. pmc Parts, wholes, and context in reading: a triple dissociation
    Denis G Pelli
    Psychology and Neural Science, New York University, New York, New York, United States of America
    PLoS ONE 2:e680. 2007
    ..Surprisingly, the effects of the knockouts on reading rate reveal a triple dissociation. Each reading process always contributes the same number of words per minute, regardless of whether the other processes are operating...
  10. ncbi request reprint Feature detection and letter identification
    Denis G Pelli
    Institute for Sensory Research, Syracuse University, Syracuse, New York, NY 13210, USA
    Vision Res 46:4646-74. 2006
    ..This, and the surprisingly fixed ratio of detection and identification thresholds, indicate that identifying a letter is mediated by detection of about 7 visual features...
  11. ncbi request reprint The remarkable inefficiency of word recognition
    Denis G Pelli
    Psychology and Neural Science, New York University, New York, New York 10003, USA
    Nature 423:752-6. 2003

    Denis G Pelli
    Psychology and Neural Science, New York University, New York, NY, USA
    J Vis 4:904-20. 2004
    ..Finally, based on these results, we introduce a new "Dual Acuity" chart that promises to be a quick diagnostic test for amblyopia...
  13. ncbi request reprint Crowding is unlike ordinary masking: distinguishing feature integration from detection
    Denis G Pelli
    Psychology and Neural Science, New York University, New York, NY, USA
    J Vis 4:1136-69. 2004
    ..The rest seem to arise through a distinct phenomenon that one might call "temporal crowding," which depends on time pressure ("overloading attention"), independent of spatial proximity...
  14. ncbi request reprint Are faces processed like words? A diagnostic test for recognition by parts
    Marialuisa Martelli
    Psychology and Neural Science, New York University, New York, NY, USA
    J Vis 5:58-70. 2005
    ..Words and faces are both recognized by parts, and their parts -- letters and facial features -- are recognized holistically. We propose that internal crowding be taken as the signature of recognition by parts...
  15. ncbi request reprint Covert attention enhances letter identification without affecting channel tuning
    Cigdem P Talgar
    Department of Psychology, New York University, New York, NY, USA
    J Vis 4:22-31. 2004
    ..We find that directing attention to the target location halves threshold energy without affecting the channel's spatial frequency tuning...
  16. ncbi request reprint The role of spatial frequency channels in letter identification
    Najib J Majaj
    Psychology and Neural Science, New York University, 6 Washington Place, New York, NY 10003, USA
    Vision Res 42:1165-84. 2002
    ..Thus, large letters (and coarse squarewaves) are identified by their edges; small letters (and fine squarewaves) are identified by their gross strokes...
  17. ncbi request reprint Flicker flutter: is an illusory event as good as the real thing?
    Tracey D Berger
    Psychology and Neural Science, New York University, New York, NY, USA
    J Vis 3:406-12. 2003
    ..Thus the unit of perceptual analysis seems to be a perceived event, independent of how it is induced...
  18. ncbi request reprint An escape from crowding
    Jeremy Freeman
    Swarthmore College, Swarthmore, PA, USA
    J Vis 7:22.1-14. 2007
    ....
  19. doi request reprint Amblyopic reading is crowded
    Dennis M Levi
    School of Optometry and Helen Wills Neuroscience Institute, UC Berkeley, Berkeley, CA 94720 2020, USA
    J Vis 7:21.1-17. 2007
    ..The uncrowded-span model of normal reading fits the amblyopic results well, with a roughly fivefold increase in the critical spacing at fixation. Thus, the entire amblyopic reading deficit is accounted for by crowding...
  20. pmc Noise masking reveals channels for second-order letters
    Ipek Oruc
    Department of Psychology, University of British Columbia, 3008 2136 West Mall, Vancouver, BC, Canada V6T 1Z4
    Vision Res 46:1493-506. 2006
    ..Unlike the nonlinear dependence found for first-order letters (implying scale-dependent processing), for second-order letters the channel frequency is half the letter texture stroke frequency (suggesting scale-invariant processing)...
