This study reports on brain activity induced by picture-based personality tests. Near-infrared spectroscopy is a newly developed, noninvasive technology in neuroimaging that can measure brain activity through blood volume changes. We measure the prefrontal cortex (Brodmann Area 10 [BA10]) activities of adolescents during the Rorschach (1921), the Rosenzweig(More)
The present study investigates how a conversational agent can facilitate explanation activity. An experiment was conducted where pairs of participants, who were enrolled in a psychology course, engaged in a task of explaining to their partners the meanings of concepts of technical terms taught in the course. During the task, they interacted with a(More)
Protein function is closely related to the structure of interaction site of the protein. Proteins that have similar structure at interaction sites often bind to the same compound. We have proposed a method for retrieving similar interaction protein using profiles that represent the features of the interaction site binding to a certain compound. Since it(More)
Male and female Crl:CD(SD) rats were fed a diet containing rubber accelerator N,N-dicyclohexyl-2-benzothiazolesulfenamide (DCBS) at 0, 80, 600 or 4500ppm throughout the study beginning at the onset of a 10-week pre-mating period and continuing through the mating, gestation, and lactation periods for two generations. At 4500ppm, decreases in the body weight,(More)
We investigated a classification method using brain computer interfaces (BCIs) for silent speech. Event-related potentials (ERPs) obtained when four subjects imagined the vocalization of two Japanese vowels while they remained silent and immobilized were recorded. We used an adaptive collection (AC) that adaptively selects suitable output signals of common(More)
