The Concept of Responsibility and Determinants of Responsibility Judgment in the Japanese Context

As in the case of the English word responsibility, the Japanese equivalent sekinin is an over-used term with multiple meanings. At least two distinctive usages are noted for the Japanese concept of responsibility: 1) to describe duties or obligations pertaining to a person's role or position; and 2) to assign blame or sanction to someone when an untoward occurrence is observed. By utilizing a number of peculiar incidents that resulted in some harm, the present study has found that subjects' responsibility judgments in terms of the second type of usage were largely determined by the following two factors: 1) the causal relationship of the agent's act to the harm that ensued; and 2) the morality of the act itself without regard to consequences. In the cases where these two aspects contradicted, especially where the blameworthy act was not directly connected to the harm, judgments about the agent's responsibility were found to diverge among subjects. It was also shown that subjects most often referred to these aspects in elucidating the reasons for attributing responsibility to, or negating the responsibility of, the agent.     

Spatial learning in Japanese eels (Anguilla japonica)

Animal Cognition - Japanese eels (Anguilla japonica) were trained on a Morris-type spatial learning task. There were four tubes in a pool, but the eels could hide in only one of these. The eels...     

Visual discrimination of normal and drug induced behavior in quails (<Emphasis Type="Italic">Coturnix coturnix japonica</Emphasis>)

The ability to discriminate the physical states of others could be an adaptive behavior, especially for social animals. For example, the ability to discriminate illness behavior would be helpful for avoiding spoiled foods. We report on an experiment with Japanese quails testing whether these birds can discriminate the physical states of conspecifics. The quails were trained to discriminate between moving video images of quails injected with psychoactive drugs and those in a normal (not injected) condition. Methamphetamine (stimulant) or ketamine (anesthetic) were used to produce drug-induced behaviors in conspecifics. The former induced hyperactive behavior and the latter hypoactive behavior. The subject quails could learn the discrimination and showed generalization to novel images of the drug-induced behaviors. They did not, however, show discriminative behavior according to the type and dosage of the drugs. Thus, they categorized the behavior not on the basis of degree of activity, but on the basis of abnormality.     

Towards a “virtual pigeon”: A new technique for investigating avian social perception

The purpose of the present study is to examine the applicability of a computer-generated, virtual animal to study animal cognition. Pigeons were trained to discriminate between movies of a real pigeon and a rat. Then, they were tested with movies of the computer-generated (CG) pigeon. Subjects showed generalization to the CG pigeon, however, they also responded to modified versions in which the CG pigeon was showing impossible movement, namely hopping and walking without its head bobbing. Hence, the pigeons did not attend to these particular details of the display. When they were trained to discriminate between the normal and the modified version of the CG pigeon, they were able to learn the discrimination. The results of an additional partial occlusion test suggest that the subjects used head movement as a cue for the usual vs. unusual CG pigeon discrimination.This contribution is part of the special issue ‘Animal Logics’ (Watanabe and Huber 2006)     

Where conscious sensation takes place

has drawn an alternative conclusion from the data of, and suggested that it takes 80 ms, rather than 500 ms, for the sensation evoked by a stimulus to enter awareness. Here, I suggest that our conscious sensation evolves over time, during the period from 80 to 500 ms after a stimulus, until the sensation is stably localized in space.     

Investigating the Relation between Imagery and Perception: Evidence from Face Priming

The relation between imagery and perception was investigated in face priming. Two experiments are reported in which subjects either saw or imagined the faces of celebrities. They were later given a speeded perceptual test (familiarity judgement to pictures of celebrities) or a speeded imagery test (in which they were told the names of celebrities and asked to make a decision about their appearance). Seeing faces primed the perceptual test, and imaging faces primed the imagery test; however, there was no priming between seeing and imaging faces. These results show that perception and imagery can be dissociated in normal subjects. In two further experiments, we examined the effects of imaging faces on a subsequent face-naming task and on a task requiring familiarity judgements to partial faces. Both these tasks were facilitated by prior imaging of faces. These results are discussed in relation to those of McDermott & Roediger (1994), who found that imagery promoted object priming in a perceptual test involving naming partial line drawings. The implications for models of face recognition are also discussed.     

Japanese television as a window on other cultures

Beginning with a brief review of issues regarding the effects of television on viewers in Japan, this paper examines how foreign programming and features relating to other countries are utilized on terrestrial television, the most influential of the mass media today. Foreign cultures are introduced either through importation of programs from abroad or through indigenous programs dealing with such topics. An overview of the changing role of imported programs emphasizes comparison of the public and commercial networks. News reporting and commercials are highlighted in a discussion of the treatment of foreign cultures in indigenous programs. Survey results show that Japanese people are favorably disposed toward foreign program imports, suggesting that the major reason for the failure of imported programs to flourish in Japan is the strong competition offered by domestic productions, not xenophobic attitudes on the part of viewers. I also consider the distinguishing characteristics of television and the cinema in order to explain the popularity of films as opposed to television dramas from abroad. In conclusion, studies that examine the effects of television on viewers' perceptions of foreign cultures are presented to suggest the importance of analyzing images of foreign cultures as depicted in programs that are domestically produced, rather than analyzing those that are imported.     

Neuroscience and nanotechnologies in Japan--beyond the hope and hype of converging technologies

Nanotechnologies are often said to be "converging" with other technologies like biotechnology, information technology, and cognitive science. And so-called "NBIC convergence" is thought to enable "enhancement" of human performance. First, I classify various kinds of enhancement. Second, I focus on the "cybernetic enhancement," to which nanotechnologies are supposed to contribute, and analyze the connection and integration of humans with machines, which could lead to the cyborgization of human beings. Third, I examine the portrayal of robot/cyborg technology in Japanese popular media, point out the tendency to empathy or ensoulment concerning robots/cyborgs, and raise the question of "ethical issues of ethical enhancement." Fourth, I compare nanotechnologies with neurotechnology and criticize the hype of "converging technologies."
