From this perspective, the self is not an internal entity, a representation that can be revealed voluntarily when directly queried by(More)
Accurate identification of cell nuclei and their tracking using three dimensional (3D) microscopic images is a demanding task in many biological studies. Manual identification of nuclei centroids from images is an error-prone task, sometimes impossible to accomplish due to low contrast and the presence of noise. Nonetheless, only a few methods are available(More)
Our life is full of invisibility that exerts power on our acts, relationships, and construction of the self. This paper discusses psychological processes in which invisibility plays an essential role, and constructs a typology of invisibility in society and in our lives. After a brief look at the crucial role of invisibility in prevailing theories of(More)

This study aimed to identify the changes in posture and muscle activity in the trunk and legs during walking in patients with LSS by examining 6 patients who had undergone decompression surgery.

Based on the recently developed Gitaigo personality scale (Komatsu, Sakai, Nishioka, & Mukoyama, 2012), we investigated the relationship between perceived personality and leading/following roles in close friend dyads. Primary participants rated their own and one of their close friend's personality with Gitaigo personality scale. They also described who(More)

Because any development is considered as emerging non-sameness, I report that the inquiry into the development of human mind must regard this tension as essential. In this paper, first I(More)
Gitaigo is a subtype of mimetic words (onomatopoeia) in the Japanese language, which can be regarded as words that imitate actions or states. This study develops a personality scale, with six subscales, using 60 gitaigo words as items for rating the personality of the self and others. We asked 1 054 participants to rate their own personality and 905(More)
Kinesiologic analysis of gait disorders, postural instabilities and abnormal movements is quite difficult to assess objectively by clinical observation, such as by specific scale and video recordings. In this study, we reported one of the aspects of the usefulness of three-dimensional motion analysis (Vicon Systems, Oxford, United Kingdom), which can(More)
