Detecting conjunctions of color and form: reassessing the serial search hypothesis.
Treisman and Gelade (1980), who had subjects search for conjunctions of color and form, observed that the slope relating reaction times to number of items in the display was twice as steep for negative (target absent) responses as for positive responses. This result is widely accepted as evidence that a serial selfterminating search is necessary to detect conjunctions. In Experiment 1 of the pr...
متن کاملLimitations on the parallel guidance of visual search: color x color and orientation x orientation conjunctions.
In visual search for a conjunction it is much more difficult to search for the conjunction of 2 colors or 2 orientations than for Color x Orientation or Color x Shape conjunctions. The result is not limited to particular colors or shapes. Two colors cannot occupy the same spatial location in Color x Color searches. However, Experiments 6 and 7 show that Color x Shape searches remain efficient e...
متن کاملDetecting Conjunctions of Global Predicates
We present an eecient algorithm to detect if the conjunction of two nonlocal predicates is possibly true in a distributed computation. For ooine detection of such global predicates, our algorithm is signiicantly more eecient than the previous algorithms
متن کاملExplaining efficient search for conjunctions of motion and form: evidence from negative color effects.
Dent, Humphreys, and Braithwaite (2011) showed substantial costs to search when a moving target shared its color with a group of ignored static distractors. The present study further explored the conditions under which such costs to performance occur. Experiment 1 tested whether the negative color-sharing effect was specific to cases in which search showed a highly serial pattern. The results s...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
