Researchers are able to estimate what subjects attend to by using eye tracking systems. Existing approaches for analyzing eye movements are very useful to estimate attention to still objects. But they are inadequate to estimate attention to moving objects, although paying attention to moving objects is usual human behavior. Thus, we propose a novel approach and algorithm to estimate attention to moving objects more precisely. Our approach is to extract "eye tracking movements". We phrase both saccadic eye movements and smooth (...) pursuit eye movements as "eye tracking movements". Because previous works reveal that humans often track a moving object by the eye movements when they pay attention to the object, our approach seems to be appropriate. Our algorithm used for extracting eye tracking movements is called Path Stitching (PS) algorithm. The PS algorithm is a kind of Longest Common Subsequence (LCS) discovery algorithms using Dynamic Time Warping (DTW) as a similarity measurement procedure. Eye tracking movements can be regarded as a situation that a subsequence of eye movements' trajectory is similar to a subsequence of the target's trajectory with a small or no time-difference. Because humans track a moving object by the eye movements with locally fluctuated time difference, we think the use of DTW is very appropriate. In addition, to make outputs more comprehensible, we employ the LCS discovery approach for the PS algorithm. The experimental results show that the PS algorithm is more able to extract eye tracking movements than the fixation extracting approach. The fixation extracting approach is the most popular and the strongest approach to analyze eye movements. Therefore, we conclude that our novel approach will advance the analysis of human behavior by the eye movements and human-computer interaction systems they utilize user's eye movements. (shrink)

BackgroundThe high incidence of post-stroke depression during rehabilitation exerts a negative effect on the treatment and functional recovery of patients with stroke and increases the risk of mortality. It is necessary to screen PSD in the rehabilitation stage and thus provide effective intervention strategies. However, existing measurements used to assess PSD in the rehabilitation stage in patients with stroke lack specificity. This study aimed to develop a clinical measure to assess symptoms of PSD in the rehabilitation stage.MethodsThe research team created (...) the initial items through a literature review and semi-structured interviews of patients with stroke. Then, the symptom-related items were estimated by three panels: healthcare professionals, Delphi experts, and patients with stroke in the rehabilitation stage.ResultsThe literature review and semi-structured interview produced 51 symptom-related items including six domains, and the items were reduced to 47 by the healthcare professionals. The symptom-related items were further reduced to 33 items by a two-round Delphi consultation. The initiative coefficients of the two Delphi rounds were 71.4 and 100%, the expert authority coefficients were both 0.85, Kendall’s W were 0.152 and 0.408, and the coefficient of variation were 0.05–0.32 and 0.00–0.18, respectively. The item-level content validity index was 0.53–1.00, the scale-level CVI/universal agreement was 0.26, and the S-CVI/average was 0.85 for the first found Delphi consultation; the I-CVI was 0.67–1.00, the S-CVI/UA was 0.61, and the S-CVI/Ave was 0.97 for the second round Delphi consultation. All content validity indicators have been significantly improved compared with the first round. Using mean ≥ 4 and full score ≥ 0.5, combined with CV ≤ 0.16 as the item criteria, a clinical measure of PSD with 33 items and 6 dimensions was finally formed after two rounds. The patients with stroke made no further revisions after evaluation.ConclusionThe research team developed a specific tool with good content validity to assess the symptoms of PSD in the rehabilitation stage.

The Miyashita experiments are very interesting and the results should be examined from a viewpoint of attractor dynamics. Amit's target article shows a path toward realistic modeling by artificial neural networks (ANN), but it is not necessarily the only one. I introduce another model that can explain a substantial part of the empirical observations and makes an interesting prediction. This model consists of such units that have nonmonotonic input-output characteristics with local inhibition neurons.

This paper explores Erich Fromm’s contribution to Deweyan democratic education by referring to his psychoanalytic interpretation of John Dewey’s pragmatic theory. First, it employs the work by Gert Biesta to secure a space between critical pedagogy and Deweyan democratic education, from which Fromm’s theory can be discussed. Furthermore, it argues that Biesta’s perspective offers a valuable theoretical ground to extend the emancipatory potential of Deweyan democratic education, while avoiding some pitfalls of critical pedagogy. Subsequently, the paper contrasts Marcuse’s and Fromm’s (...) views on Dewey to show how Fromm’s understanding of Dewey was more effective than that of Marcuse for developing the potential of Dewey’s philosophy. Next, the paper clarifies key similarities and differences between Fromm’s psychoanalysis and Dewey’s pragmatism, as it is applicable specifically to emancipatory education. Finally, the paper argues that despite the differences between these two thinkers, Fromm’s theory further radicalizes Deweyan democratic education by adding new elements to the list of preconditions on the role of the emancipatory teacher.

This paper offers an alternative historical account of debate in Japan during the Meiji, Taishō, and early Shōwa eras. Most previous studies on the modern history of debate in Japan have focused on Yukichi Fukuzawa or political advocacy by voluntary associations in the Freedom and People’s Rights Movement. Contrary to the prevailing view that debate had largely dissipated by 1890 due to the government’s strict regulations and crackdowns, this paper demonstrates that debate continued to be an important activity of youth (...) clubs across the nation. Emerging around the late 1880s, those youth clubs regularly held intra-group debates on various topics in order to advance knowledge in academic and practical matters. This paper concludes by suggesting that far from suppressing debates altogether, political authorities tolerated, and even promoted, certain forms of debate which they deemed fit for producing active yet subservient citizens.

Prediction is essential for the efficiency of many cognitive processes; however, this process is not always perfect. Predictive coding theory suggests that the brain generates and updates a prediction to respond to an upcoming event. Although an electrophysiological index of prediction, the stimulus preceding negativity, has been reported, it remains unknown whether the SPN reflects the prediction accuracy, or whether it is associated with the prediction error, which corresponds to a mismatch between a prediction and an actual input. Thus, the (...) present study aimed to investigate this question using electroencephalography. Participants were asked to predict the original pictures from pictures that had undergone different levels of pixelation. The SPN amplitude was affected by the level of pixelation and correlated with the subjective evaluation of the prediction accuracy. Furthermore, late positive components were negatively correlated with SPN. These results suggest that the amplitude of SPN reflects the prediction accuracy; more accurate prediction increases the SPN and reduces the prediction error, resulting in reduced LPC amplitudes.

This paper offers a novel argument for fatalism: if one accepts the logical possibility of fatalism, one must accept that fatalism is true. This argument has a similar structure to the ‘knowability paradox’, which proves that if every truth can be known by someone, then every truth is known by someone. In this paper, what I mean by ‘fatalism’ is that whatever happens now was determined to happen now in the past. Existing arguments for fatalism assume that the principle of (...) bivalence holds even for future propositions, that past truths are necessarily true, and/or that possible propositions never change into impossible propositions. However, my argument does not assume such premises. It assumes only the logical possibility of fatalism. Here, what I mean by ‘fatalism is logically possible’ is that there is at least one possible world where whatever happens now was determined to happen now in the past. Since this assumption is weak (thus is plausible), I believe it to be much stronger than the existing arguments for fatalism. In addition, I also show that what will happen in the future is determined now. (shrink)

This paper aims to distinguish two main types of coarse graining, and reveal the relationship between the notions of coarse graining and emergence. In physics, some forms of coarse graining seem to be indispensable to show a physical property, and the other merely changes our descriptions of the system. To clarify the notion of coarse graining, this article investigates the cases of the renormalization group method and irreversibility, both of which have been important topics in philosophy of science, and the (...) case of the rigid body in classical mechanics, which is an elementary case including coarse graining. The case studies reveal the distinction between substantial and mere coarse-graining. This distinction clarifies the relationships between the notions of coarse graining and emergence and further provides some implications for the issues about emergence. (shrink)

This study posits that Bohr failed to defend the completeness of the quantum mechanical description of physical reality against Einstein–Podolsky–Rosen’s paper. Although there are many papers in the literature that focus on Bohr’s argument in his reply to the EPR paper, the purpose of the current paper is not to clarify Bohr’s argument. Instead, I contend that regardless of which interpretation of Bohr’s argument is correct, his defense of the quantum mechanical description of physical reality remained incomplete. For example, a (...) recent trend in studies of Bohr’s work is to suggest he considered the wave-function description to be epistemic. However, such an interpretation cannot be used to defend the completeness of the quantum mechanical description. (shrink)

Japanese conversational data reveal that Japanese speakers produce, and recipients orient to, smaller units of talk than what the conventional notion of a `turn constructional unit' represents. Unlike TCUs, such units may be grammatically, prosodically and pragmatically incomplete and may happen on the sub-phrasal level of discourse, as Japanese conversationalists prosodically break up even a single semantic constituent with the insertion of an interactional particle. In this article, I give numerous examples of how such practices of separating a segment of (...) talk are not random but are precisely embedded in the sequential organization of talk that participants co-create. I argue that such segmentation contributes to the interactional co-construction of a turn so as to highlight specifically a `move' Within the larger action that is implemented by the TCU. Doing so thereby provides opportunities for the participants to deal with local contingency problems without changing the global level of the pragmatic work of the turn. (shrink)

Philosophers have long discussed whether time really passes. Simultaneously, they have also discussed whether time could have begun from an infinite past. This paper clarifies the relationship between the reality of time’s passage and an infinite past. I assert that time cannot have an infinite past if time really passes. This argument is based on a proposition that an infinite series of events cannot be completed if time really passes. A seemingly strong objection to this proposition is that no movement (...) is possible if an infinite series cannot be completed. However, movement is clearly possible; thus, an infinite series can be completed. I argue that although it is sure that an infinite series can be completed in the static view, an infinite series cannot be completed (and thus, time could not have begun from an infinite past) in the dynamic view.

Context holds a significant place mediating the conceptual and the empirical in ethnography. This modality of knowledge has also become a significant part of science and technology studies since the rise of laboratory studies. However, conventional modes of contextualization that locate the object of study within a whole—such as within a society or culture—have become a target of suspicion and criticism since the 1980s. This led to the radical alteration of the contextualizing strategies of actor–network theory and multisited ethnography. Anthropologist (...) Marilyn Strathern is also responding to this crisis by renovating the practice of ethnography in a way significantly different from both strategies. Since contextualization occupies a significant place in the formation of ethnography as a representation of a larger “out there” reality, her alternative contextualization requires a new characterization of ethnography other than representation. This article tries to expound the complicated, and often perplexing, ethnography of Strathern by making an analogy with objects familiar to most science, technology, and society scholars, namely, machines. By doing so, this article argues that Strathern is opening up a new way of dealing with context that is radically different both from ANT and from multisited ethnography. (shrink)
