The preview benefit: Visual marking, feature-based inhibition, temporal segregation, or onset capture?
"... The preview effect demonstrates that if observers in a visual search task are allowed a preview of a subset of elements before another subset of elements is added to the display, the first subset of elements no longer competes for attentional selection in the search process. Watson and Humphreys (19 ..."

views have emerged. According to one notion, a feature-based inhibition account, the preview benefit is mediated by inhibition applied at the level of feature maps in addition to location-based inhibition. A second view, the temporal segregation hypothesis, assumes that prioritized selection of new

Loopy belief propagation for approximate inference: An empirical study. In:
- Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

modification to the update rules in that we normalized both ..\ and 1r messages at each iteration. As Pearl Nodes were updated in parallel: at each iteration all nodes calculated their outgoing messages based on the incoming messages of their neighbors from the pre vious iteration. The messages were said
Conjunction search revisited
- Journal of Experimental Psychology: Human Perception and Performance
, 1990
"... Search for conjunctions of highly discriminable features can be rapid or even parallel. This article explores, three possible accounts based on (a) perceptual segregation, (b) conjunction detectors, and (c) inhibition controlled separately by two or more distractor features. Search rates for conjunc ..."

Priming in macaque frontal cortex during popout visual search: Feature-based facilitation and location-based inhibition of return
- Journal of Neuroscience
, 2002
"... In popout search, humans and monkeys are affected by trialto-trial changes in stimulus features and target location. The neuronal mechanisms underlying such sequential effects have not been examined. Single neurons were recorded in the frontal eye field (FEF) of monkeys performing a popout search du ..."

during which stimulus features and target position changed unpredictably across trials. Like previous studies, repetition of stimulus features improved performance. This feature-based facilitation of return was manifested in the target discrimination process in FEF: neurons discriminated the target from
Time-Course of Feature-Based Top-Down Control in Saccadic Distractor Effects
"... Saccadic reaction time (SRT) is more strongly slowed by target-similar than dissimilar distractors (similarity effect). The time course of this similarity effect was investigated by varying target contrast and analyzing SRT distributions. With foveal distractors, the similarity effect increased with ..."

attribute to location-based inhibition containing the growing enhancement of target features. Strong inhibition was likely with peripheral distractors because they always appeared at the same task-irrelevant location. Prior inhibition with foveal distractors was weaker because this would have partially
Spatial and Feature-Based Attention in a Layered Cortical Microcircuit Model
"... Directing attention to the spatial location or the distinguishing feature of a visual object modulates neuronal responses in the visual cortex and the stimulus discriminability of subjects. However, the spatial and feature-based modes of attention differently influence visual processing by changing ..."

A crucial assumption of the model is that feature-based attention activates orientation-specific microcircuits
Remembering can cause forgetting: Retrieval dynamics in long-term memory
- Journal of Experimental Psychology: Learning, Memory, & Cognition
, 1994
"... Three studies show that the retrieval process itself causes long-lasting forgetting. Ss studied 8 categories (e.g., Fruit). Half the members of half the categories were then repeatedly practiced through retrieval tests (e.g., Fruit Or). Category-cued recall of unpracticed members of practiced catego ..."

Experiments 2 and 3 identified 2 significant features of this retrieval-induced forgetting: The impairment remains when output interference is controlled, suggesting a retrieval-based suppression that endures for 20 min or more, and the impairment appears restricted
A new vertical diffusion package with an explicit treatment of entrainment processes
