Takamasa Hattori, Yoji Yamada, Shogo Okamoto, Shuji Mori, Shunsuke Yamada, Characteristics and individual differences of human actions for avoiding harm to eyes from a robot, Journal of Robotics and Mechatronics, 26, 358-368, 2014.05, In this study, psychological experiments were conducted to investigate harm-avoidance actions in humans in close contact with robotic devices. For the experiments, a situation was created in which the sharp end-effector tip of a robot suddenly approached the eyes of a facing participant. We define three parameters for analyzing harm-avoidance actions: the avoidance reaction time, maximum avoidance acceleration, and maximum avoidance speed. The results suggest that the avoidance reaction time depends on the initial distance between the human’s eyes and the approaching object but not on the type of work being performed. We derive a novel nonparametric multiple comparison method for statistically testing multivariate data on human actions. The test results show that the bivariate data of the avoidance reaction time and maximum avoidance speed differ for most pairs of participants. These findings can contribute to determining human–robot conditions for safe coexistence. .

20. Lawrence M. Ward, Michael Baumann, Graeme Moffat, Larry E. Roberts, Shuji Mori, Matthew Rutledge-Taylor, Robert L. West, Achieving across-laboratory replicability in psychophysical scaling, Frontiers in Psychology, doi:10.3389/fpsyg.2015.00903, 6, 1-15, 2015.07, [URL], It is well known that, although psychophysical scaling produces good qualitative agreement between experiments, precise quantitative agreement between experimental results, such as that routinely achieved in physics or biology, is rarely or never attained. A particularly galling example of this is the fact that power function exponents for the same psychological continuum, measured in different laboratories but ostensibly using the same scaling method, magnitude estimation, can vary by a factor of three. Constrained scaling (CS), in which observers first learn a standardized meaning for a set of numerical responses relative to a standard sensory continuum and then make magnitude judgments of other sensations using the learned response scale, has produced excellent quantitative agreement between individual observers’ psychophysical functions. Theoretically it could do the same for across-laboratory comparisons, although this needs to be tested directly. We compared nine different experiments from four different laboratories as an example of the level of across experiment and across-laboratory agreement achievable using CS. In general, we found across experiment and across-laboratory agreement using CS to be significantly superior to that typically obtained with conventional magnitude estimation techniques, although some of its potential remains to be realized..

Wataru Teramoto, Takuyuki Nakazaki, Kaoru Sekiyama, Shuji Mori, Effects of word width and word length on optimal character size for reading of horizontally scrolling Japanese words, Frontiers in Psychology, doi: 10.3389/fpsyg.2016.00127, 7, 1-8, 2016.02, [URL], The present study investigated, whether word width and length affect the optimal character size for reading of horizontally scrolling Japanese words, using reading speed as a measure. In Experiment 1, three Japanese words, each consisting of four Hiragana characters, sequentially scrolled on a display screen from right to left. Participants, all Japanese native speakers, were instructed to read the words aloud as accurately as possible, irrespective of their order within the sequence. To quantitatively measure their reading performance, we used rapid serial visual presentation paradigm, where the scrolling rate was increased until the participants began to make mistakes. Thus, the highest scrolling rate at which the participants’ performance exceeded 88.9% correct rate was calculated for each character size (0.3, 0.6, 1.0, and 3.0) and scroll window size (5 or 10 character spaces). Results showed that the reading performance was highest in the range of 0.6 to 1.0, irrespective of the scroll window size. Experiment 2 investigated whether the optimal character size observed in Experiment 1 was applicable for any word width and word length (i.e., the number of characters in a word). Results showed that reading speeds were slower for longer than shorter words and the word width of 3.6 was optimal among the word lengths tested (three, four, and six character words). Considering that character size varied depending on word width and word length in the present study, this means that the optimal character size can be changed by word width and word length in scrolling Japanese words..

Tomokazu Urakawa, Nobuyuki Hirose, Shuji Mori, Reduction in the reverse-bias effect by an abrupt break in the sequential regularity of visual events, Perception, 10.1177/0301006615622321, 45, 474-482, 2016.04, A bistable image is more likely to be initially perceived as the reversal of its preceding unambiguous version presented for a prolonged period. This perceptual bias is called the reverse-bias effect. We hypothesized that an abrupt break in the sequential regularity of visual events, synchronized with the onset of a bistable image, counteracts the reverse-bias effect in a similar manner to the disturbing effect of noise in the perceptual process. Under the condition in which the reverse-bias effect was achieved with the Necker lattice, the orientation of the bars around the lattice was simultaneously changed at the onset of the lattice, yielding an abrupt break in the sequential regularity of visual events besides the lattice. The results obtained showed that the reverse-bias effect was significantly reduced by the abrupt break, suggesting that an abrupt break in the sequential regularity of visual events perturbs the perceptual bias of the bistable image, similar to that caused by noise..
