Distributed cortical networks for focused auditory attention and distraction.
We used behavioral measures and functional magnetic resonance imaging (fMRI) to study the effects of parametrically varied task-irrelevant pitch changes in attended sounds on loudness-discrimination performance and brain activity in cortical surface maps. Ten subjects discriminated tone loudness in sequences that also included infrequent task-irrelevant pitch changes. Consistent with results of...
متن کاملCapturing focused attention.
When attention is diffuse, as in a visual search task, an abrupt onset almost invariably succeeds in capturing attention. But if attention had been cued in advance to a different location, the same onset may then fail to capture attention (Theeuwes, 1991; Yantis and Jonides, 1990). In previous demonstrations, the onset appeared frequently. This may have diminished the onset's novelty, which in ...
متن کاملAttention to Different Cues in Noun Learning: The Effect of English vs. Spanish Mass/Count Syntax
1. Introduction Children generalize nouns in ways that are consistent with the referent s ontological and/or grammatical kind. In other words, children generalize a new noun based on both the perceptual properties of the referent and the linguistic Cross-linguistic studies have shown that systematic differences in the structures of different languages are reflected in children s novel noun gene...
متن کاملFocused attention vs. crossmodal signals paradigm: deriving predictions from the time-window-of-integration model
In the crossmodal signals paradigm (CSP) participants are instructed to respond to a set of stimuli from different modalities, presented more or less simultaneously, as soon as a stimulus from any modality has been detected. In the focused attention paradigm (FAP), on the other hand, responses should only be made to a stimulus from a pre-defined target modality and stimuli from non-target modal...
متن کاملWhen paying attention becomes counterproductive: impact of divided versus skill-focused attention on novice and experienced performance of sensorimotor skills.
Two experiments examined the impact of attention on sensorimotor skills. In Experiment 1, experienced golfers putted under dual-task conditions designed to distract attention from putting and under skill-focused conditions that prompted attention to step-by-step putting performance. Dual-task condition putting was more accurate. In Experiment 2, right-footed novice and experienced soccer player...
