Modeling representational shifts in learning the number line
On the basis of findings from an experiment with 6-year-old children we show a proposal for a cognitive model of representational shifts in learning the number line. The findings from the experiment provide information on number line estimation that is, translating a number to a spatial position on a number line. Though the experiment is a replication of an experiment done by Siegler and Ramani...
متن کاملMultiple-location access in vision: evidence from illusory line motion.
Four experiments with undergraduates used illusory line motion (ILM) to contrast Z. W. Pylyshyn's (1989) FINST theory of spatial indexing with predictions made by unitary attention models. Multiple-onset stimuli were able to cause ILM at disparate, noncontiguous spatial locations. Consistent with gradient explanations of ILM and with FINST theory predictions, varying line-drawing speed and the ...
متن کاملThe motion-induced shift in the perceived location of a grating also shifts its aftereffect.
Motion can bias the perceived location of a stationary stimulus (Whitney & Cavanagh, 2000), but whether this occurs at a high level of representation or at early, retinotopic stages of visual processing remains an open question. As coding of orientation emerges early in visual processing, we tested whether motion could influence the spatial location at which orientation adaptation is seen. Spec...
متن کاملUnbiased shifts of Brownian motion
Let B = (Bt)t∈R be a two-sided standard Brownian motion. An unbiased shift of B is a random time T , which is a measurable function of B, such that (BT+t−BT )t∈R is a Brownian motion independent of BT . We characterise unbiased shifts in terms of allocation rules balancing mixtures of local times of B. For any probability distribution ν on R we construct a stopping time T ≥ 0 with the above pro...
متن کاملVisual motion shifts saccade targets.
Saccades are made thousands of times a day and are the principal means of localizing objects in our environment. However, the saccade system faces the challenge of accurately localizing objects as they are constantly moving relative to the eye and head. Any delays in processing could cause errors in saccadic localization. To compensate for these delays, the saccade system might use one or more ...
