Abstract The psychological effects of low-dose caffeine combined with polyphenols from apples have rarely been explored scientifically yet synergistic are plausible. A randomized, double-blind, placebo-controlled cross-over experiment was used to test the apple extract beverages 10, 20, 37.5, and 75 mg caffeine. Comparisons were made both a placebo drink that artificially sweetened colored mimi...

Older adults commonly report difficulties in visual tasks of everyday living that involve visual clutter, secondary task demands, and time sensitive responses. These difficulties often cannot be attributed to visual sensory impairment. Techniques for measuring visual processing speed under divided attention conditions and among visual distractors have been developed and have established constru...

Speed of information processing was assessed in patients with multiple sclerosis and healthy controls using both an auditory and visual task designed to control for accuracy of performance across groups. After controlling for accuracy of performance, patients with multiple sclerosis were found to have significantly slower speed of information processing relative healthy controls, irrespective o...

In this paper, we present the information search system using object category recognition, which is queried by image from mobile phone camera or from photo sharing service on internet. In such system, processing speed is an important requirement. We adopted “Standard Model” proposed by T. Serre in 2005, and improved processing speed by replacing Gabor filter to Haar wavelet, vector quantization...
