Smooth-pursuit eye velocity to a moving target is more accurate after an initial catch-up saccade than before, an enhancement that is poorly understood. We present an individual-differences-based method for identifying mechanisms underlying a physiological response and use it to test whether visual motion signals driving pursuit differ pre- and postsaccade. Correlating moment-to-moment measurem...

The coordination of saccadic and smooth pursuit eye movements in macaque monkeys was investigated using a target selection paradigm with two moving targets crossing at a center fixation point. A task in which monkeys selected a target based on its color was used to test the hypothesis that common neural signals underlie target selection for pursuit and saccades, as well as testing whether targe...

Spatial perception is modulated by eye movements. During smooth pursuit, perceived locations are shifted in the direction of the eye movement. During active fixation, visual space is perceptually compressed towards the fovea. In our present study, we were interested to determine the time course of spatial localization during pursuit initiation, i.e. the transition period from fixation to steady...

Given that ―rule-based analysis is the dominant form of reasoning‖ used by lawyers, it is probably safe to say that most lawyers would agree with Aristotle‘s sentiment. After all, this is how lawyers are taught to think in law school. Three years of their lives are slavishly devoted to the pursuit of logic with little to no emphasis on other forms of reasoning. Therefore, it is not surprising t...

The most beautiful mathematics to Godfrey Harold Hardy was that which had no application. For Hardy, mathematics was purely for intellectual challenge. He justified the pursuit of pure mathematics with the argument that its very “uselessness” meant that it could not be used to cause harm. Hardy went so far as to describe applied mathematics as “ugly”, “trivial”, and “dull” [1]. Despite Hardy’s ...

The inspiration for this study is the observation that swing dancing involves coordination of actions between two humans that can be accomplished by pure haptic signaling. This study implements a leaderfollower dance to be executed between a human and a PHANToM haptic device. The data demonstrate that the participants’ understanding of the motion as a random sequence of known moves informs thei...

The extant forest sector strategy research rests on Porter’s classic dictum that successful firms pursue a singular strategy. A growing research stream on organizational ambidexterity, however, challenges this traditional view and recommends the pursuit of hybrid strategies, a phenomenon that we note existing among forest sector firms. In this study, we set out to compare the financial performa...

When small objects move in a scene, we keep them foveated with smooth pursuit eye movements. Although large objects such as people and animals are common, it is nonetheless unknown how we pursue them since they cannot be foveated. It might be that the brain calculates an object's centroid, and then centers the eyes on it during pursuit as a foveation mechanism might. Alternatively, the brain me...

Gottlob Frege Patricia A. Blanchette Abstract Gottlob Frege (1848-1925) made significant contributions to both pure mathematics and philosophy. His most important technical contribution, of both mathematical and philosophical significance, is the introduction of a formal system of quantified logic. His work of a more purelyphilosophical kind includes the articulation and persuasive defense of a...
