Global motion processing depends on a network of brain regions that includes extrastriate area V5 in the dorsal visual stream. For this reason, psychophysical measures of global motion perception have been used to provide a behavioral measure of dorsal stream function. This approach assumes that global motion is relatively independent of visual functions that arise earlier in the visual process...

Previous work has found that women with anorexia nervosa and bulimia nervosa have weak coherence. The aim of this study was to examine whether women who had recovered from an eating disorder (ED) also had weak coherence. A total of 42 recovered ED women and 42 healthy women were assessed with a battery of five neuropsychological tests that measure aspects of global or local functioning. The rec...

We investigate the global integration of local motion direction signals in amblyopia, in a task where performance is equated between normal and amblyopic eyes at the single element level. We use an equivalent noise model to derive the parameters of internal noise and number of samples, both of which we show are normal in amblyopia for this task. This result is in apparent conflict with a previo...

Time and frequency domain analyses of scalp EEG recordings are widely used to track changes in brain states under general anesthesia. Although these analyses have suggested that different spatial patterns are associated with changes in the state of general anesthesia, the extent to which these patterns are spatially coordinated has not been systematically characterized. Global coherence, the ra...

It is possible to define conversation policies, such as communication or dialogue protocols, that are based strictly on what messages and, respectively, what performatives may follow each other. While such an approach has many practical applications, such protocols support only „local coherence“ in a conversation. In a mixed-initiative dialogue between two agents cooperating on some joint task,...

It is possible to define conversation policies, such as communication or dialogue protocols, that are based strictly on what messages and, respectively, what performatives may follow each other. While such an approach has many practical applications, such protocols support only "local coherence" in a conversation. Lengthy message exchanges require some infrastructure to lend them "global cohere...

INTRODUCTION Clinical encounters are often assessed using a checklist. However, without direct faculty observation, the timing and sequence of questions are not captured. We theorized that the sequence of questions can be captured and measured using coherence scores that may distinguish between low and high performing candidates. METHODS A logical sequence of key features was determined using...
