Attending to a location shortens the perceptual latency of stimuli appearing at this location (perceptual latency priming). According to attentional explanations, perceptual latency priming relies on the speeded transfer of attended visual information into an internal model. However, doubts about the attentional origin have repeatedly been raised because efforts to minimize response bias have b...

We identify Twitterusing CEOs and examine the impact of their social media activity on the corporate performance...

I classify CEOs as overoptimistic based on their option exercise behavior, and find that overoptimistic CEOs are more likely to pay with cash when market-wide valuations are (moderately) above their long-term trend, but not when market valuations are low. In contrast to rational CEOs, overoptimistic CEOs view their stock as overly costly and prefer cash payment, even during times of high market...

The present study quantified nasalward/temporalward biases in monocular optokinetic nystagmus (MOKN) and perceived velocity in patients with either early onset esotropia, late onset esotropia and in normals. MOKN was measured with low spatial frequency, small-field gratings drifting at 9.4 degrees/s. MOKN bias was quantified as the ratio of nasalward slow-phase velocity divided by the sum of te...
