This study focused on satisficing in online surveys—behavior in which panels do not devote an appropriate amount of attentional resources when answering questions. It carried out questionnaire surveys that could not be answered properly without closely reading the instructions and questions to empirically investigate the prevalence and patterns of satisficing. To detect satisficing tendencies, a screening survey was conducted with questions that necessitated a close reading of the instructions, while the main survey used questions that required a close reading of the item content. Identical surveys were carried out at two different survey companies, and results showed that satisficing due to skipping instructions occurs very frequently. Furthermore, while satisficing due to skipping scale items appears to be relatively rare, trends in satisficing differed between the survey companies. These results indicate one method for preventing satisficing, which was discussed in relation to the merits and demerits of screening respondents with satisficing tendencies.

This research applies spatial statistics to examine proximal factors affecting the political behavior of voters in a regional election in Japan, particularly, voter proximity to the election campaigns of the candidates. During the mayoral election in Akō City, Hyōgo Prefecture, voters’ political behavior, attitudes, and awareness of politics were measured using a social survey, the spatial location information relating to candidates’ election campaigns being measured using GPS. Voters’ favorable perception of a certain candidate was positively correlated to the degree of contact with his election campaign of voters themselves or that of their neighborhood, but not to spatial proximity with his campaign. On the other hand, both the degree of contact and spatial proximity with his election campaign of voters themselves led them to cast their votes for the candidate, even controlling for favorability. It was revealed that there is a possibility for proximal factors to be treated more precisely by applying spatial statistics.

In this article, we investigated the expression of emotional responses to the 2011 Great East Japan Earthquake by analyzing the frequency of negative emotional terms in tweets posted on Twitter, one of the most popular social media platforms. We focused on differences in time-series variations and diurnal changes between two kinds of disasters: natural disasters (earthquakes and tsunamis) and nuclear accidents. The number of tweets containing negative emotional responses increased sharply shortly after the first huge earthquake and decreased over time, whereas tweets about nuclear accidents showed no correlation with elapsed time. Expressions of anxiety about natural disasters had a circadian rhythm, with a peak at midnight, whereas expressions of anger about the nuclear accident were highly sensitive to critical events related to the accident. These findings were discussed in terms of similarities and differences compared to earlier studies on emotional responses in social media.

In this article, monitor attitudes during online surveys were empirically examined, focusing in particular on satisficing (when survey participants do not fully engage their efforts). At first, the extent to which the satisficing tendency was dependent on personal traits was examined. We observed participants’ behavior in an online survey setting that required them to view video stimulus material consisting of news footage, and measured the length of time each participant spent viewing the footage. The results revealed that respondents who had satisficed (half-heartedly read) the scale items in a prior study (Miura & Kobayashi, 2015) were much more likely to satisfice the video footage. Then, agenda-setting and media-priming effects were used to examine the impact of satisficing during online surveys (including experimental manipulation) on empirical findings. Both examinations indicated the strong possibility that data pertaining to participants who satisficed could serve to distort empirical findings.

「2ちゃんねる」は日本最大のオンラインコミュニティサイトである.ところが,そこに書き込まれる情報はときとして「便所の落書き」と揶揄されるように,一見すると意味のない言葉や記号にしか見えないものも多い.これは非常に奇妙な現象である.というのも,便所の落書きを見るために毎日数十万人もの人が訪れるとはとても考えられないからである.ではなぜ2ちゃんねるはあれほど盛り上がっているのだろうか.実は傍から見れば意味がないように思える言葉や記号のやりとりが2ちゃんねるのユーザには意味があり,これが2ちゃんねるが盛り上がる要因となっているのかもしれない.このような動機から本稿では,2ちゃんねるにおけるコミュニケーションの特徴に着目して,2ちゃんねるが盛り上がるダイナミズムを解き明かすことを目指す.特に,コミュニケーションの特徴として,メッセージのサイズや投稿数,返信率,投稿される早さなどの基本的な属性に加え,2ちゃんねるに特徴的な名無しと,2ちゃんねる語やアスキーアート(AA)などの定型的な表現技法に注目する.共分散構造分析により構築した「2ちゃんねるモデル」は,定型的表現傾向が議論発散傾向と議論深化傾向に及ぼす関係などを明らかにしている.2channel' is the most popular online-community site in Japan,where millions of participants are chitchatting or discussing various topics.However, this fact sometimes confuses us because most of messages in 2channelseem to be meaningless, often said as graffiti. To understand the mystery of 2channel, we assume the existence of something at the back of 2channel that governs the activity of participants.Looking at 2channel from this point of view, there could be many factors that affect online communication. For example, terms that seem to be meaningless for usmight have some meanings for participants in 2channel,and communication with the terms might activate interaction.In this paper, we aim at analyzing the dynamism of 2channel by applying Structural Equation Modeling (SEM) to eight observable characteristics of communicationincluding basic properties (message size, posting activity, reply rate, etc), anonymity, and specific expressions (jargons and ASCII arts peculiar to 2channel).The structural equation model of 2channel clearly shows various causalities among the characteristics,i.e. the use of specific expressions affects positively to chitchat-type communication, and negatively to discussion-type communication.

This study focused on perceived relationship conflict and task conflict within groups and investigated the possible misperceptions and differences in preferences of conflict management behavior. Both types of conflict were manipulated in a crossed design with respect to their conflict level, resulting in four different scenarios (i.e., low conflict, relationship conflict, task conflict, and mixed conflict situations). Two hundred and thirty-one undergraduate students were asked to answer (1) perceived task and relationship conflict within each scenario and (2) preferred management behavior in that situation. Results showed that both types of conflict could be misperceived with regard to the other. Avoidant management behavior was preferred more in the relationship conflict situation than the task conflict situation. In addition, preferred management behavior in the mixed conflict situation, where both relationship and task conflict were strongly perceived, was the same as the management behavior in the relationship conflict situation. Differences in management behavior in each conflict situation were discussed based on the dual process theory.

This study investigated the effect of moral foundation and feeling of disgust toward acriminal case on non-professional legal decisions. Three hundred and sixty participantswere asked to read a fictional story about a murder attempt case and rated a possi-bility that a defendant, who had denied all charges against the case, would be judgedas guilty. Participants were also rated a degree of regrets about their decision if thetruth would be either guilty or not guilty. The degree of physical injury of a victim wasvaried in accordance with three conditions (i.e., minor, heavy, and permanent damage).The analysis revealed that participants who put much value on not harming others feltdisgust toward the criminal case, and that resulted in higher ratings of possibility thatthe defendant would be judged as guilty. In addition to that, as the degree of physi-cal injury of the victim got severer, the ratings of the possibility also got higher, andparticipants felt less regrets of their decision even if the defendant was actually nota real perpetrator and thus they made Type II error. We discussed characteristics ofnon-professional legal decisions from both theoretical and practical perspectives.

Web-based knowledge-sharing communities, which are supported by countless voluntary Internet users, are in widespread use today. We explored a number of characteristics of interpersonal communication among participants based on their questioning and answering behaviors. A questionnaire survey on participants of Yahoo! Chiebukuro, one of the most popular knowledge-sharing communities in Japan, was conducted, and access data of their behavior in the community were collected. Based on 7,989 survey samples and access data, we found that there were several significant differences in their behavior and motivation based on their participation style, question content, and gender. Results also suggested that information was exchanged and accumulated actively in the community and interpersonal communication of community participants was developed by an aggressive need for information acquisition and subsequent social support.

本研究では,集団討議で生じる葛藤と対処行動,およびメンバーの主観的パフォーマンスの関連について検討した。4名からなる合計17集団(68名)にランダムに配置された大学生が,18分間の集団課題を遂行した。その際,討議開始前,中間,終了時に,メンバーの意見のずれから算出される実質的葛藤を測定した。また討議終了時には,中間から終了にかけて認知された2種類の葛藤の程度,および葛藤対処行動について回答を求めた。分析の結果,集団内の実質的葛藤は相互作用を通して変遷すること,また,中間時点の実質的葛藤は主観的パフォーマンスと関連が見られないものの,終了時点の葛藤の高さは主観的パフォーマンスを低下させることが示された。関係葛藤の高さと回避的対処行動は主観的パフォーマンスの低さと関連し,統合的対処行動は主観的パフォーマンスの高さと関連していた。関係葛藤と課題葛藤の交互作用効果も示され,課題葛藤の程度が低い場合は,関係葛藤が低い方が高い方よりも主観的パフォーマンスが高くなる一方で,課題葛藤の程度が高い場合にはそのような差はみられなかった。葛藤の測定時点の重要性,および多層的な検討の必要性について議論した。

This study examined the effects of the reactions of younger adukts toward older adults on the psychological attributese and behavior of elderly. Participants were 34 older male adults aged 60-82 years. They completed a questionnaire on generativity before and after the experimental condition, and were also observed taking flyers on different topics after the experiment. They were assigned to the younger condition or the same generation condition. In both conditions, the participants were asked to talk to recipients about experiences from their youth and the wisdom they have gained. The recipients responded to the participants in either a positive or a neutral way. The results showed that generativity was promoted most when the younger recipients responded in a positive manner, whereas the neutral reactions of younger recipients led to the inhibition of generativity. Younger persons’ positive reactions promoted the participants’ helping behaviors, as indicated by the flyers they took. The present study shows increases in the generativity of the elderly following positive reactions from younger recipients not only on questionnaires but also in an experimental setting.

In this article, we investigate “retweeting in Twitter” or information transfer behavior in social media to figure out some characteristics of our information processing behavior in emergency situation from social psychological perspective. We made an exploratory log analysis of Twitter focusing on the relationship between diffusion of disaster information and user's emotional response on them. Disaster-related tweets which were retweeted over 10 times around the time of the Great East Japan Earthquake were extracted and emotional words in them were categorized and counted. Frequently retweeted tweets tended to include more negative (anxious or angry) or active emotional words than positive or inactive words. As results of multiple and quantile regression analyses, negative (especially anxious) or active emotional words in tweets had a significant effect on the increase of retweeting regardless of a kind of disasters. The results were discussed in terms of the difference with those based on common tweets.

This study focused on an online knowledge-sharing community, in which information was exchanged and accumulated actively in the community based on the question-and-answer interaction of users. We examined its characteristics by text mining, one of the most effective methods for the content analysis of enormous quantities of text-based data. Based on an analysis of posted questions and answers, the same gender difference as in previous studies on interpersonal communicative discourse was found. Female users tended to post questions and answers related to their interpersonal relationships. Based on an analysis of their perspectives on the community, it was suggested that many users positively evaluated the usefulness of the community and did not hesitate to post questions and answers. These attitudes of users toward the community should lead to their positive evaluation of both the overall community and the communication made there, as pointed out by Miura and Kawaura (2008).

Although the spread of the “high-choice” Internet brings a great deal of attention to research in partisan-selective exposure, there are not many people choosing media based on their partisanship in reality. On the other hand, preference-based selective exposure, widening gaps in knowledge about political or international news between news seekers and entertainment fans as a result of reducing opportunities for incidental or by-product exposure to news in a high-choice media environment, may become a serious problem in a society made up of less partisan voters. This research focused on this selective exposure and, using an online survey, examined whether online services would widen or narrow voters’ gaps in political knowledge. The results indicate that while exposure to portal sites, newspaper sites, and summary of 2-channel sites decrease in the gap, exposure to news curation applications and Twitter increase in the gap. The implications for possible change in the media environment are discussed.

This study examined chronological changes in attitudes towards foodstuffs from the areas contaminated by the Fukushima Daiichi nuclear disaster, using citizens’ data (n=1,752) from the panel surveys conducted in 4 waves between September 2011 and March 2014. Using the dual process theory of decision-making, the study attempts an empirical examination that includes the interaction of two factors: (1) anxiety regarding the radiation risks of the nuclear accident, which is hypothesized to lead to negative emotional decision-making following the formation of relevant attitudes, and (2) knowledge, higher-order literacy, and critical thinking, which are hypothesized to promote logical decision-making. Until three years after the nuclear accident, there was no large chronological variation in either anxiety regarding the radiation risks of the nuclear accident or attitudes toward foodstuffs from affected areas. The tendency regarding the latter was particularly strong in areas far from the location of the disaster. Negative attitudes regarding foodstuffs from affected areas were reduced through the possession of appropriate knowledge regarding the effects of radiation on the human body. However, the belief of possessing such knowledge may, conversely, hinder careful consideration with appropriate understanding.

This study focuses on “satisficing” (answering behaviors in which participants do not devote appropriate attentional resources to the survey (Krosnick, 1991)) in an online survey and aims to investigate, via various indices, to what extent these behaviors are observed among students whose participation was solicited by the researchers in their universities. This study also aims to explore effective techniques to detect individuals who show satisficing tendencies as efficiently and accurately as possible. Online surveys were carried out at nine universities. Generally speaking, the predictive capability of various types of detection indices was not high. Though direct comparison with online survey panels was impossible because of differences in measurement methodology, the satisficing tendencies of university students were generally low. Our findings show that when using university students as samples for a study, researchers need not be “too intent” on detecting satisficing tendencies, and that it was more important to control the answering environment, depending on the content of the survey.

2011 年 3 月 11 日に発生した東日本大震災においては,Twitter に多くのメッセージが投稿された.これまで,緊急時におけるマイクロブログの有用性が示されているものの,地域を考慮したマイクロブログの利用傾向に関する分析は十分に行われていない.本研究では,マイクロブログとして Twitter に着目し,東日本大震災発生後に Twitter へと投稿されたツイートを分析した.分析の結果,以下の知見を得た.(1) 被害の大きかった地域では直接的なメッセージのやり取りが行われる傾向がある.一方,被害の小さかった地域では,ツイートされた情報が拡散される傾向が高い.(2) 特に被害の大きい地域で発信された情報については,他地域へと移動する傾向が見られた.After the Great Eastern Japan Earthquake in Japan 2011, numerous tweets were exchanged on Twitter. Several studies have already pointed out that micro-blogging systems have shown potential advantages in emergency situations, but it remains unclear how people use them. This paper presents a case study of how people used Twitter after the Great Eastern Japan Earthquake. First, we gathered tweets immediately after the earthquake and analyzed various factors, including locations. The results revealed two findings: (1) people in the disaster area tend to directly communicate with each other. On the other hand, people in the other area prefer tend to rely on re-tweet; (2) information posted from the disaster area tends to spread in the other area.

This study defined Belief in Just World (BJW) multidimensionally and investigated the effects of Belief in Immanent Justice (BIJ) and Belief in Ultimate Justice (BUJ) on victim derogation and draconian punishment of perpetrators. Study 1 tested the validity of the multidimensional structure of BJW and demonstrated relationships between BJW and other psychological variables. In Study 2, we measured the reactions to the victim and perpetrator in an injury case reported in a news article, and evaluated the relationships of these reactions to BIJ and BUJ. The results revealed that BIJ was associated with a preference in draconian punishment of the perpetrator, while BUJ was associated with dissociation from the victim (a type of victim derogation). In addition, as hypothesized, we found that dehumanization of the perpetrator partially mediated the relationship between BIJ and victim derogation. We discussed relationships between the two types of BJW and just-world maintenance strategies in the situation where a victim and a perpetrator are both recognized.
