Dominic Schnider, an analyst at UBS Wealth Management, said it might not have been the eurozone that triggered the mass flight out of gold: "What we now see is panic selling, perhaps triggered by the Fed's stimulus view.
Bicoherence evolutions at (4, 4) as functions of time for subject E01: (a) over Fp2 and O1 for a flash stimulus viewed through the left eye, (b) over Fp2 and O2 and the left eye, (c) over Fp2 and O1 and the right eye, (d) over Fp2 and O2 and the right eye.
Bicoherence evolutions at (20, 20) as functions of time for subject E05 for a flash visual stimulus viewed through the left eye: (a) over F4 and C4, (b) over F4 and Fp2, (c) over F4 and O2 and (d) over F4 and O1.
This enabled confirmation of stimulus viewing, and offered a cogent behavioral marker to confirm that subjects paid attention to the stimuli.
Stimulus viewing was monocular via each participant's dominant eye to eliminate confounding effects of binocular fixation disparity [70] and each non-dominant eye was occluded using a light-proof eye-patch (Cambridge Research Systems).
Approach and avoidance behavior can also be modeled by data from a validated keypress procedure [14] [21] that is used within an intrinsic motivation-like framework in which no external rewards are provided [22], [23], yet participants can produce variable amounts of work [24], [25] to modulate the time of stimulus viewing.
Eyes were refracted for the stimulus viewing distance (one meter).
Moreover, the improvement was specific to the particular stimulus viewed whilst running.
Finally, we examined whether stimulus onset transients (0 300 ms) could be classified according to the orientation of the stimulus viewed.
First, they allowed a very tight control over some crucial stimulus properties, such as size, because the stimulus viewing distance was constant and reproducible across trials and sessions.
