It is widely accepted that the amygdala plays a critical role in acquisition and consolidation of fear-related memories. Some of the more widely employed behavioral paradigms that have assisted in solidifying the amygdala's role in fear-related memories are associative learning paradigms. With most associative learning tasks, a neutral conditioned stimulus (CS) is paired with a salient uncondit...

BACKGROUND In recent computerized cognitive training studies, video games have emerged as a promising tool that can benefit cognitive function and well-being. Whereas most video game training studies have used first-person shooter (FPS) action video games, subsequent studies found that older adults dislike this type of game and generally prefer casual video games (CVGs), which are a subtype of ...

A transmogrifier is a novel interface that enables quick, onthe-fly graphic transformations. A region of a graphic can be specified by a shape and transformed into a destination shape with real-time, visual feedback. Both origin and destination shapes can be circles, quadrilaterals or arbitrary shapes defined through touch. Transmogrifiers are flexible, fast and simple to create and invite use ...

This dissertation describes a series of studies conducted to explore why people use information visualizations during their non-work time (casual InfoVis) and which factors are critical for visualization adoption and long duration use. I also model typical casual InfoVis usage patterns and provide a framework for future hypothesis testing. Each study explored a different facet of casual InfoVis...

Internet-connected devices, especially mobile devices such as smartphones, have become widely accessible in the past decade. Interaction with such devices has evolved into frequent and short-duration usage, and this phenomenon has resulted in a pervasive popularity of casual games in the game sector. On the other hand, development of casual games has become easier than ever as a result of the a...

OBJECTIVE To determine the reproducibility of casual arterial pressure measurement and to confirm pressure diagnosis by monitoring of participants in the ELSA-Brasil (Estudo Longitudinal de Saúde do Adulto - Brazilian Longitudinal Study for Adult Health). METHODS Casual blood pressure was measured with an oscilometric device. A sub-sample of participants (N = 255) from Espírito Santo state (S...

bstract—Cyclic AMP has been shown to have a critical role n learning and memory in invertebrates. Here we use the rat up odor preference learning model in which odor acts as a onditioned stimulus and -adrenoceptor stimulation acts as n unconditioned stimulus to test the role of cyclic AMP in an ssociative mammalian paradigm. A phosphodiesterase inibitor that prevents cyclic AMP breakdown (cilom...
