Irrelevant stimuli in S-R discontiguity

Stimulus-response spatial contiguity vs. S-R spatial discontiguity in auditory spatial tasks. I. Acquisition by normal dogs.

Twelve dogs were trained in spatial tasks with auditory location cues. One group, tested on delayed response with stimuli and responses spatially contiguous, solved the task at once, whereas the other group, trained with actual stimuli and responses spatially discontiguous, attained criterion after errors. The differences in behavior of these groups suggest that two learning strategies may be i...

Discrimination of behaviorally irrelevant auditory stimuli in stage II sleep.

In sleep, the brain responds to significant stimuli such as one's own name or loud tones. It is, however, not yet known whether in sleep, the brain's response can vary systematically with change in an irrelevant stimulus. Here, we varied the intensity of a 1000 Hz tone and recorded the neural response of the participants by using electroencephalography. The P200 component of the auditory-evoked...

نگاشت های R - s - پیوسته

کلاس جدیدی از نگاشتهای پیوسته، به نام نگاشت های R - s - پیوسته ، معرفی میشود. ارتباط میان R - s - پیوستگی با پیوستگی و انواع دیگری ازپیوستگیهای قوی که تاکنون معرفی شده اند، بررسی میشود. سپس ویژگیهای نگاشتهای R - s - پیوسته مورد مطالعه قرار میگیرد.

Momentary reductions of attention permit greater processing of irrelevant stimuli

Momentary reductions of attention can have extremely adverse outcomes, but it remains unclear whether increased distraction from irrelevant stimuli contributes to such outcomes. To investigate this hypothesis, we examined trial-by-trial relationships between brain activity and response time in twenty healthy adults while they performed a cross-modal selective attention task. In each trial, part...
