  1. ncbi request reprint Motion tracking modulates capacity allocation of visual working memory
    Joo Hyun Song
    Harvard University, Cambridge, Massachusetts, USA
    Psychon Bull Rev 13:1011-5. 2006
    ..We suggest that coherent motion between two temporally disparate arrays connects the arrays into a single visual event. VWM is then biased toward remembering the more recent state of the event...
  2. ncbi request reprint Numeric comparison in a visually-guided manual reaching task
    Joo Hyun Song
    Department of Psychology, Harvard University, Cambridge, MA, USA
    Cognition 106:994-1003. 2008
    ..Direct evidence for an analogue representation of numbers was found in early as well as in later portions of hand trajectories, showing systematic shifts in position for small differences in numerical magnitude...
  3. doi request reprint Automatic adjustment of visuomotor readiness
    Joo Hyun Song
    Department of Psychology, Harvard University, Cambridge, MA, USA
    J Vis 7:2.1-9. 2007
    ..We conclude that visuomotor readiness is automatically adjusted by the recent experience of trial difficulty...
  4. ncbi request reprint Role of focal attention on latencies and trajectories of visually guided manual pointing
    Joo Hyun Song
    Department of Psychology, Harvard University, Cambridge, MA, USA
    J Vis 6:982-95. 2006
    ..In addition, the presence of highly curved movement trajectories, directed first to a distractor then to the target reflects ongoing changes in focal attentional deployment and target selection...
  5. ncbi request reprint Fixation offset facilitates saccades and manual reaching for single but not multiple target displays
    Joo Hyun Song
    Department of Psychology, Harvard University, 33 Kirkland Street, WJH 710, Cambridge, MA 02138, USA
    Exp Brain Res 177:223-32. 2007
    ..Our results suggest that the gap may facilitate attentional disengagement, but it does not help target selection in motor and perceptual discrimination tasks, where the allocation of attention to the target is required...
  6. doi request reprint Target selection in visual search as revealed by movement trajectories
    Joo Hyun Song
    Department of Psychology, Harvard University, 33 Kirkland Street, Cambridge, MA 02138, USA
    Vision Res 48:853-61. 2008
    ..In addition, our results show that the details of movement trajectories allow us to visualize the dynamics of target selection as they unfold in time...

    Joo Hyun Song
    The Smith Kettlewell Eye Research Institute, San Francisco, CA 94115, USA
    Trends Cogn Sci 13:360-6. 2009
    ..Thus, this line of research provides new opportunities to integrate information across different disciplines such as perception, cognition and action, which have usually been studied in isolation...

    J Neurophysiol 102:2681-92. 2009

    Joo Hyun Song
    Smith Kettlewell Eye Research Institute, 2318 Fillmore St, San Francisco, CA 94115, USA

    Yuhong Jiang
    Department of Psychology, Harvard University, Cambridge, Massachusetts 02138, USA
    Psychon Bull Rev 12:524-9. 2005

    J Neurophysiol 103:2124-38. 2010

    J Exp Psychol Hum Percept Perform 31:1439-48. 2005
    ..Similar results held when items changed shapes after training. The authors conclude that implicit visual learning is sensitive to trial context and that spatial context learning can be identity contingent...
  13. ncbi request reprint Connecting the past with the present: how do humans match an incoming visual display with visual memory?
    Joo Hyun Song
    Department of Psychology, Harvard University, Cambridge, MA, USA
    J Vis 5:322-30. 2005
    ..We suggest that the retrieval of a well-established visual memory can proceed even if an incoming display partly matches the previous memory...
