The Concurrent Programming of Saccades [PDF]
PLOS ONE, 2016 Sequences of saccades have been shown to be prepared concurrently however it remains unclear exactly what aspects of those saccades are programmed in parallel. To examine this participants were asked to make one or two target-driven saccades: a reflexive saccade; a voluntary saccade; a reflexive then a voluntary saccade; or vice versa. During the first

Sensing Pico‐Newton Plasmonic Forces and Jerks of LSPR Biochips Using Simple UV‐Visible Spectroscopy
Advanced Physics Research, EarlyView.The figure represents the interaction of light interaction with a nanostructured plasmonic system. Incident light excites localized surface plasmon resonance (LSPR) and induces radiation forces on the nanostructures, as illustrated by the force vectors.

Vision Research, 1999 Saccadic localization of spatially extended objects requires the computation of a single saccadic landing position. What representation of the target guides saccades? Saccades were examined for various targets composed of dots to determine whether landing position corresponded to the center-of-gravity (average location) of the dots, the center-of-area ...

Prescribing competence: The pros and cons of different methods for assessment
British Journal of Clinical Pharmacology, EarlyView.Evaluating a medical graduate’s competence in rational prescribing is challenging. With the aim to guide and inspire teachers, this narrative review explores different methods that can be used to assess prescribing competence. Each method has its own advantages and disadvantages, and thus a mix of different assessment methods is needed throughout the ...

Frontiers in Human Neuroscience, 2011 Gap and overlap tasks are widely used to promote automatic versus controlled saccades. This study examines the hypothesis that the right posterior parietal cortex (PPC) is differently involved in the two tasks. Twelve healthy students participated in the

Saccadic undershoot is not inevitable: Saccades can be accurate
Vision Research, 1986 Saccades normally take the eye 90% of the way to a target, followed by a 10% corrective saccade. An exception to this rule occurs with the range effect. When targets appear in a set of positions, saccades overshoot the near positions and undershoot the far. This phenomenon, previously reported, was confirmed with more accurate methods. The range effect

Knowledge acquisition in science and the blurred boundary between perception and cognition
British Educational Research Journal, EarlyView.Abstract This paper provides a critical and detailed study of what researchers in the fields of contemporary cognition and neuroscience have revealed about the blurred boundary between perception and cognition. We set out the arguments with a view to what researchers and teachers should now consider regarding the subtleties of their interrelationship ...

Monetary reward speeds up voluntary conditional saccades
Frontiers in Integrative Neuroscience, 2014 Past studies have shown that reward contingency is critical for sensorimotor learning, and reward expectation speeds up saccades in animals. Whether monetary reward speeds up saccades in human remains unknown.

Saccadic momentum and facilitation of return saccades contribute to an optimal foraging strategy. [PDF]
PLoS Computational Biology, 2013 The interest in saccadic IOR is funneled by the hypothesis that it serves a clear functional purpose in the selection of fixation points: the facilitation of foraging. In this study, we arrive at a different interpretation of saccadic IOR. First, we find

Pre-saccadic perception: separate time courses for enhancement and spatial pooling at the saccade target [PDF]
, 2017 We interact with complex scenes using eye movements to select targets of interest. Studies have shown that the future target of a saccadic eye movement is processed differently by the visual system.
