With the expansion of psychological studies conducted online, researchers show greater interest in the quality of the data collected from online studies. Factors that may compromise the data quality include lack of control of environmental variables, nonnaïveté due to repeated participation, and reduced attention to the study materials. In this study, we examined the possibility that type of device and the presentation format of study materials may compromise the quality of responses. An online study with a total of 1,005 crowd-workers (PC=485, mobile=520) revealed that mobile devices were associated with less attentive responses. Results also showed that mobile devices tended to elicit relatively inconsistent responses to psychological scales, specifically when combined with the multiple presentation formats, in which all items of the scale were presented at once. The results suggest that the importance of considering the type of device and the format of information presentation in the future studies conducted online. Future research in this domain should further address factors that may lower the quality of data, such as demographics.

In this study, we examined the fidelity of online cognitive–behavioral experiments conducted with Japanese crowd workers. Four cognitive tasks (flanker task, mental rotation task, levels-of-processing task, and mood induction task involving the recall of autobiographical memories) were performed by Japanese crowd workers in a web-based setting and by students in a lab-based setting. We found that all task-specific effects were replicated, except mood induction did not affect perceived social support in both crowd workers and students. The present results validate the fidelity of conducting online experiments with Japanese crowd workers.

Recently, the artificial hand has been studied and developed for the various purposes. One of them is hand prosthesis. There are many important problems in hand prosthesis. In developing an artificial hand, points to be remarked are the mechanism, the driving method, the driving circuit and the way to make it small and light.Imitating the shape and function of a human hand, we made a prototype model in order to clarify the problems of practical use.First merit of this phototype is having the possibility of operation by two different commands. One command uses a command disk. By turning the disk, the artificial hand repeats the predeturmind sequence of operation. The other command uses the EMG from the human hand.Second merit is in its function. The five fingers and the wrist move independently, so that it can perform complicated actions that are similar those performed by a human hand.Finally, the problems with this prototype model are taken up suggesting the countermeasures and making a prospect of future.

目的論とは,「水が存在するのは,地球で生命を生き残らせるためである」というように,自然現象が何らかの目的を持って存在するという考えである。目的論的信念は成人でもみられ (Kelemen & Rosset, 2009), 自然科学者であっても認知負荷がかかると目的論的信念を正しいと判断しやすくなるなど (Kelemen et al., 2013), 対象が目的や意図を持つという目的論的信念は直観的であり, 人のデフォルトの説明機序である可能性が指摘されている。本研究では日本人参加者を対象に,目的論的信念と認知的直観性・熟慮性との関係を検討した。その結果,認知負荷のある状態では目的論的信念を正しいと判断しやすく, また,認知的熟慮性は目的論的信念と負の傾向に関係にあることが明らかとなった。日本人においても,自然現象を理解する際に, 直観的過程では目的論的信念に従った解釈をしやすい可能性が示された。

The normal position of the anus is not defined objectively. Using a simple technique, the anal position index was designed to define the position of anus in neonates and infants as follows: the ratio of the distance between the scrotum and the anus to the distance between the scrotum and the coccyx for males and the distance between the vagina and the anus to the distance between the vagina and the coccyx for females. The anal position index in neonates was not affected by body weight. In male infants, the anal position index was not affected by age. But in female infants, the anal position index decreased from neonatal period to three months of age but no significant difference was demonstrated from three months of age to twelve months of age. We think that the anal position index is useful as an objective parameter to assess the localization of the anus.
