    Visual orienting attention has been researched thoroughly using visual cues, and spatial attention and temporal attention have been compared using brain-imaging data [1]. However, while several studies have reported on auditory attention, the attention was not oriented using a cue. In addition, fewer studies have compared spatial and temporal attention using auditory stimuli. We compared visual and auditory orienting attention using a visual cue. We asked whether a general system exists for auditory spatial and temporal attention that conforms to that of visual spatial and temporal attention. We measured brain activity in 16 healthy volunteers using functional magnetic resonance imaging (fMRI). The attention was manipulated spatially and temporally using a visual cue for both visual and auditory tasks in a factorial design. Symbolic central cues oriented the subjects toward spatial location only (left or right), toward the temporal interval only (300 or 1800 ms), or gave no information about the spatial location or temporal interval. The subjects were also scanned under a resting basetine condition during which they clicked the reaction key ten times. Behavioral data showed the same tendency in visual and auditory tasks. The reaction time for spatial location attention was faster than that for temporal interval attention. The brain-imaging data showed a partial overlap between visual spatial attention and auditory spatial attention. In addition, it revealed a partial overlap between the neural systems involved in the performance of visual spatial attention versus visual temporal attention. The parietal and frontal cortices were activated in both the visual and auditory spatial attention tasks. The parietal cortex was activated in the visual temporal attention task only and not in the auditory temporal task. ©2007 IEEE.

    Retinotopic mapping is one of the most important experimental procedures in brain mapping the human visual system. Due to technical problems in previous studies applying fMRI retinotopy on human subjects, which typically used a central and/or pericentral visual field stimulus (8-30 deg of eccentricity from the fixation point), retinotopic characteristics of peripheral vision in humans are still unclear. To overcome this obstacle, we developed the wide-view visual presentation system with a horizontal visual angle of 120 deg and a vertical angle of 120 deg using nonmagnetic optical fibers and contact lens for fMRI. In this paper, we introduce the functions and performance of this system and report the results of our evaluative experiment. © 2007 IEEE.

  • Development and evaluation of a device for presenting tactile stimuli

    We are especially interested in the human ability to recognize shape using the delayed matching paradigm in active and passive touch studies. To investigate the characteristics of shape recognition, stimulus presentation control is very important because a subtle difference in the stimulus presentation will influence the results. In this study, we propose a new device that precisely controls the stimulus presentation and performs psychobehavioral measurements in haptics studies. And we also conducted an active/passive shape discrimination experiment to evaluate the performance of the device. Twenty right-handed students consented to participate in the experiment. The results suggest that the device might serve as a comprehensive haptic device that allows different types of haptic stimuli to be presented precisely to subjects to measure various psychobehavioral parameters. © 2007 IEEE.

    In the paper, we propose a multi-aspect data mining process for investigating a more whole human information process mechanism systematically. As an example to demonstrate the proposed mining process, we explain how to design the experiments of an ERP mental arithmetic task with visual stimuli for investigating human computation centric information processing mechanism, and describe how to do multi-aspect analysis in the obtained ERP data, respectively. Furthermore, we give some preliminary results to show the usefulness of our methodology and to discuss the future research directions. © 2007 IEEE.

    Although many cognitive and brain scientists have already studied human information processing mechanism of auditory and visual, separately, the relevance between auditory and visual information processing needs to be investigated in depth. We investigate human multi-perception mechanism by combining various psychological experiments, physiological measurements, data cleaning, modeling, transformation and mining techniques for developing artificial systems which match human ability in specific aspects. In particular, we observe fMRI (functional magnetic resonance imaging) brain activations from the view point of peculiarity oriented mining and propose a way of peculiarity oriented mining for knowledge discovery in multiple human brain data. We present an interesting result on modeling, transforming, and mining multiple human brain data obtained from visual and auditory psychological experiments by using the fMRI. The proposed methodology attempts to change the perspective of cognitive scientists from a single type of experimental data analysis towards a holistic view. © 2004 Elsevier B.V.
