  1. ncbi request reprint Visual short-term memory for sequential arrays
    Arjun Kumar
    Harvard University, Cambridge, Massachusetts, USA
    Mem Cognit 33:488-98. 2005
    ..We suggest that multiple displays compete for retention in VSTM and that separating information into two temporally discrete groups does not enhance the overall capacity of VSTM...
  2. doi request reprint Failure to find executive function deficits following one night's total sleep deprivation in university students under naturalistic conditions
    Edward F Pace-Schott
    Department of Psychiatry, Harvard Medical School, Beth Israel Deaconess Medical Center, Boston, MA 02215, USA
    Behav Sleep Med 7:136-63. 2009
    ..Behavioral and physiological adaptation to chronically sleep-restricting lifestyles may confer resistance to the cognitive effects of sleep deprivation in high-functioning young adults...
  3. ncbi request reprint Integrating sequential arrays in visual short-term memory
    Yuhong Jiang
    Department of Psychology, Harvard University, Cambridge, MA 02138, USA
    Exp Psychol 52:39-46. 2005
    ..In this study, we show that success in this task can be better accounted for by a convert-and-compare process than by an integration process. We conclude that VSTM only supports limited integration across sequential arrays...
  4. ncbi request reprint Visual short-term memory for two sequential arrays: one integrated representation or two separate representations?
    Yuhong Jiang
    Massachusetts Institute of Technology, Cambridge, Massachusetts, USA
    Psychon Bull Rev 11:495-500. 2004
    ..This effect was observed only at an ISI of 500 msec or longer. We propose that as Array 1 is better consolidated, its representation becomes more separated from that of Array 2...
  5. pmc A common neural network for cognitive reserve in verbal and object working memory in young but not old
    Yaakov Stern
    Cognitive Neuroscience Division of the Taub Institute, NY, USA
    Cereb Cortex 18:959-67. 2008
    ..This spatial pattern could represent a general neural instantiation of CR that is affected by the aging process...
  6. pmc The response-signal method reveals age-related changes in object working memory
    Arjun Kumar
    Division of Cognitive Neuroscience, Taub Institute, Columbia University, New York, NY 10032, USA
    Psychol Aging 23:315-29. 2008
    ..Results suggest that in working memory, aging impairs both the maximum capacity for discriminability and the rate of information accumulation, but not the temporal threshold for discriminability...
