Fortunate Conjunctions Revived: Feature Binding with the 2f-ST2 Model
Temporal feature binding in vision refers to the process by which features of objects presented one after the other at the same spatial location are correctly bound together. In this paper, we describe a computational model of putative neural mechanisms that would produce this behaviour. These simulations highlight the role of transient attentional enhancement in mediating the temporal binding ...
متن کاملFeature Conjunctions in Visual Search
Selective Tuning (ST) [1] presents a framework for modeling attention and in this paper we show how it performs in visual search tasks. Two types of tasks are presented, a motion search task and an object search task. Both tasks are successfully tested with different feature and conjunction visual searches.
متن کاملFeature conjunctions and auditory sensory memory.
This study sought to obtain additional evidence that transient auditory memory stores information about conjunctions of features on an automatic basis. The mismatch negativity of event-related potentials was employed because its operations are based on information that is stored in transient auditory memory. The mismatch negativity was found to be elicited by a tone that differed from standard ...
متن کاملEffect of feature similarity on illusory conjunctions.
In four experiments, we examined whether the phenomenon of illusory conjunctions is constrained by feature similarity. Specifically, are illusory conjunctions more likely to occur between items with similar features than between items with dissimilar features? Feature similarity was manipulated in two dimensions: color and shape. Experiment 1 demonstrated that more illusory conjunctions occur b...
متن کاملSpatial Attention in Visual Search for Features and Feature Conjunctions
Spatial attention was measured in visual search tasks using a spatial probe . Both speed and accuracy measures showed that in a conjunction task, spatial attention was allocated to locations according to the presence of target features. Also, contrary to some predictions, spatial attention was used when a clearly distinguishable feature defined the target. The results raise questions about any ...
