- Auditory temporal resolution
keyword : Auditory Perception, Temporal Processing, Auditory Brainstem Response, Magnetoencephalography
2018.04Across-frequency gap detection Our auditory system is good at detection a silent gap in otherwise continuous sounds. However, such gap detection deteriorates when the gap is inserted at the point of frequency change in the sound. This is called across-frequency gap detection, and we are now investigating its underlying mechanism by psychophysical experiments, measurement of brain activity, and simulations of cochlear functions.. - Between-channel processing of perception of time, space, and speech
keyword : Auditory Perception, Channel, Time, Space, Speech
2013.04~2018.03Across-frequency gap detection Our auditory system is good at detection a silent gap in otherwise continuous sounds. However, such gap detection deteriorates when the gap is inserted at the point of frequency change in the sound. This is called across-frequency gap detection, and we are now investigating its underlying mechanism by psychophysical experiments, measurement of brain activity, and simulations of cochlear functions.. - Psychophysics of Japanese reading
keyword : Japanese, reading, letter recognition
2008.04~2015.03Psychophysics of Japanese reading This research investigate stimulus factors (letter size, contrast, etc.) and individual factors (age, native language, etc) that possibly affect reading and letter recognition of Japanese by psychophysical experiments.. - Sport psychophysics
keyword : sport, psychophysics, anticipation, reaction time, induced motion
2001.01~2015.03Sport psychophysics Sport psychophysics is a branch of psychophysics that study perceptual and cognitive abilities specific to athletes, i.e. expertise perception, by psychophysical measurement methods. Our initial research focused on karate athletes, measuring their reaction times, expectation, and eye movements. The results show that these measures are quite different between karate athletes and non-athletes (Mori et al., 2002, Human Movement Science; Seya & Mori, Visual Cognition, in press). We are now studying expertise perception of penalty kicks in soccer, side-by-side steps in Rugby, and tennis forhand strokes, using video-filmed motions of the athletes, and point-light displays (biological motion) and computer graphics coverted from the motions.. - Reaction time and arousal level during automobile driving
keyword : driving, reaction time, arousal level
2007.04~2012.03Reaction time and arousal level during automobile driving Reaction times to external stimuli during automobile driving, and driver's arousal level are closely related to occurence of automobile accindents. In order to predict probability of collision during automobile driving and promote safety driving, we are now investigating driver's reaction times and arousal level under simulated driving situations.. - Auditory search in frequency and intensity
keyword : audition, search, frequency, intensity, tonal sequence
2001.04~2006.03Auditory search in frequency and intensity To understand perception and attention of sounds in the temporal dimension, we study auditory search performance for a target in tonal sequence. Search is easier as the target and non-targets are increasing different in frequency, which is modelled in terms of attention band (Mori & Wong, 2004, Journal of Physiological Anthropology and Applied Human Science). However, the model does not fit intensity effects on search, and we are now working on new models.. - Reference frame for human orientation processing
keyword : orientation processing, reference frame, visual search, rod-frame illusion, orientation contrast
2001.01~2004.01Reference frame for human orientation processing Human vision is quite sensitive to orientation difference, while such orientation sensitivity is greatly modulated by a reference frame. This research investigated effects of reference frame on orientation processing in visual search experiments. The results showed that three mechanisms contribute to the effects, namely distraction by frame components, orientation contrast, and interference in local orientation processing (for details, Mori & Kataoka, 2004, Perception & Psychophysics)..
- We investigated mechanisms of across-channel processing in audition, in JSPS grant (Kaken A).
- A a part of joint research with Rion Co.Ltd, we aim to find methodologies to objectively estimate human auditory temporal resolution.
- Japan Society for the Promotion of Science Grants-in-Aid for Scientific Research Challenging Research (Exploratory)
- Development of methods enabling efficient and fast measurements of gap detection thresholds and temporal modulation functions that are indices of human auditory system, and denoising methods of auditory brainstem response
