According to the BLE specifications [36], a device can operate in either of four distinct roles, namely broadcaster, observer, peripheral and central.
In 2008, the Bush administration further cheapened the practice by eliminating requirements for "buffer zones" that prohibited mining within 100 feet of flowing streams.With such lax rules in place, tangles between the EPA and companies running mountaintop-removal coal mines proceed over what seem to the observer to be peripheral details.
This index is calculated as a ratio between non detected stimuli and all the peripheral stimuli presented to the observer.
Here, we used a dual-task paradigm [4], [5] to examine whether the temporal contrast sensitivity for a peripheral drifting grating is altered when observers are attentively engaged in the central letter recognition task.
Observers adapted to a peripheral patch of noise surrounded by four Gabor flankers.
Observers monocularly viewed a peripheral crowded stimulus positioned at 10° eccentricity, which counterphase flickered at 2 Hz.
Fig. 7 illustrates the mean latencies for all six individual observers in both the peripheral (panel A) and central (panel B) conditions.
However, when click-pairs were accompanied by peripheral visual stimuli that activated the magnocellular pathway, observers were more accurate than when there were no visual stimuli.
Observers discriminated the orientation of a peripheral Gabor patch embedded in visual noise while performing a central task (Fig. 3).
Observers saw two different conditions of the peripheral escalator illusion: one with a narrow background grating (i.e., the width of columns) and one with a wide background grating (i.e., about 2.5 times the width of the columns).
Half the observers started with three sessions of the peripheral cue condition and then completed the three central cue sessions.
