attentional vision
NLM Language scientists have traditionally considered language in isolation from other cognitive and perceptual systems such as attention, vision, and memory.
Each letter subtended ∼0.65° horizontally of the visual angle and 0.8° vertically.

This volume provides a comprehensive overview of the nature of attentional and visual processes involved in language comprehension. The “baseline” (or 0% signal change) was defined as the mean activity during the 6 sec preceding each target. Attention shift task.

The study of multimodal interactions and attentional processes during language processing has thus become an important theoretical focus that guides many research programs in psycholinguistics and related fields. For sensory regions that respond more to audition than to vision, we constructed a contrast involving 24 weighted regressors, including regressors associated with six time points after each of the four targets (hold audition, hold vision, switch from audition to vision, and switch from vision to audition). The visual display contained a target stream of letters at fixation and four surrounding distractor streams. He has been working at the Centre for more than a decade.

This design permits the measurement of the neural events that are time locked to the act of shifting attention, unconfounded by sensory responses to a distinct attention cue. He has a master's degree in electrical engineering from the Indian Institute of Science and subsequently earned his PhD in psychology from the University of Georgia, USA in 1996.
Either vision or audition was attended at the beginning of a run.
Nevertheless, larger interference effects were observed when the distractor matched both the stimulus of the primary as well as the secondary modality and this pattern was even stronger if vision was the primary modality than if audition was the primary modality.

We measured how long the object continued to interfere with the second, and hence the time course of the first object's attentional demand. Attention and cardiac phase boost judgments of trust.

The central visual stream or the central (binaural) auditory stream contained target digits to be detected and identified; distractor streams of letters were continuously present in both modalities. Whole-brain echoplanar functional images (EPIs) were acquired with a sensitivity-encoding (SENSE) head coil (MRI Devices, Waukesha, WI).
Language scientists have traditionally considered language in isolation from other cognitive and perceptual systems such as attention, vision and memory.
This crossover pattern reflects the dynamics of sensory modulation during a crossmodal shift of attention. USA.gov.
High-resolution anatomic images were acquired with a T1-weighted, 200 slice magnetization-prepared rapid gradient echo sequence with SENSE level 2 (TR, 8.1 msec; TE, 3.8 msec; flip angle, 8°; prepulse T1 delay, 852.1 msec; isotropic voxels, 1 mm). These results corroborate and extend previous demonstrations of attentional modulation within vision and audition, respectively (Moran and Desimone, 1985; O'Craven et al., 1997; Tzourio et al., 1997; Jancke et al., 1999; Reynolds et al., 1999; Yantis et al., 2002), and confirm that our task effectively recruited selective attention and therefore could be used to examine the control of crossmodal attention shifts.

A second contrast was conducted with the opposite sign to identify regions that respond more to visual than to auditory input. Sind Sie der Meinung, dass dieser Artikel Urheberrechte verletzt?
