• visual
  • Most people are unable to initiate pursuit without a moving visual signal. (wikipedia.org)
  • Pursuit is modified by ongoing visual feedback. (wikipedia.org)
  • Videos of hunts by a gyrfalcon ( Falco rusticolus ), gyrfalcon ( F. rusticolus )/Saker falcon ( F. cherrug ) hybrids and peregrine falcons ( F. peregrinus ) were analyzed to determine apparent prey positions on their visual fields during pursuits. (biologists.org)
  • The simplest strategy is classical pursuit, in which the pursuer (the predator) always flies directly toward the evading prey ( Nahin, 2012 ) ( Fig. 1A ), so the evader's image is centered on the pursuer's visual field. (biologists.org)
  • human
  • The economy of the Paleolithic communities consisted mainly of exploiting natural resources: gathering, fishing and especially hunting were the main pursuits of the diverse human groups. (wikipedia.org)
  • system
  • Such moderately impaired pursuit tracking might be related to inattention or medication, an underlying central nervous system disorder, or advanced age. (tchain.com)
  • data
  • Another source of difficulty is that the lack of a standard pursuit paradigm associated with a well defined normal data set. (tchain.com)
  • These video data were then interpreted using computer simulations of pursuit steering laws observed in insects and mammals. (biologists.org)
  • Here, we consider how animal-borne video data can distinguish between different proposed pursuit strategies that use perceptual cues from the environment. (biologists.org)
  • necessary
  • After the founding of the Soviet Union in 1922, Lenin had introduced a mixed economy, commonly referred to as the New Economic Policy, which allowed for capitalist practices to resume under the Communist Party dictation in order to develop the necessary conditions for socialism to become a practical pursuit in the economically undeveloped country. (wikipedia.org)
  • clear
  • Finally, it is also clear that pursuit performance declines with age (Zackon and Sharpe, 1987). (tchain.com)
  • attention
  • Various lines of research suggests a tight coupling for closed loop pursuit and spatial attention. (wikipedia.org)
  • Pursuit performance is strongly affected by attention, and inattentive or uncooperative subjects can perform poorly without having any significant central lesion. (tchain.com)
