Gist Perception and Holistic Processing in Rapidly Presented Mammograms.

A critical role of holistic processing in face gender perception

Whether face gender perception is processed by encoding holistic (whole) or featural (parts) information is a controversial issue. Although neuroimaging studies have identified brain regions related to face gender perception, the temporal dynamics of this process remain under debate. Here, we identified the mechanism and temporal dynamics of face gender perception. We used stereoscopic depth ma...

Holistic Processing in Speech Perception: Experts' and Novices' Processing of Isolated Cantonese Syllables

Holistic processing is an expertise marker in visual perception. Here we tested participants’ perception of Cantonese syllables through composite paradigm commonly used for measuring holistic processing in vision research. We found that participants were more holistic in processing syllable initials than finals, possibly because initials are shorter and more easily combined with neighboring seg...

Dyslexia, magnocellular integrity and rapidly presented stimuli

Conlon at al. (2011, Brain and Cognition, 76, 197-205) studied the responses of dyslexic readers and controls to rapidly presented stimuli. They found that the dyslexic readers showed poorer performance than the controls but only when the interstimulus interval (ISI) was short (150 ms), not when it was long (350 ms). This difference they attributed to a magnocellular or dorsal stream deficiency...

Enhanced stimulus contrast normalizes visual processing of rapidly presented letters in Alzheimer’s disease

Deficient perception and cognition in Alzheimer's disease (AD) has been attributed to slow information processing and attentional disturbance, but an additional explanation may be reduced signal strength. In 21 individuals with probable AD, 29 healthy older and 54 younger adults, we enhanced the contrast level of rapidly-flashed masked letters. The AD group reached identification criterion (80%...
