A Comparison of Hindsight Bias in Groups and Individuals: The Moderating Role of Plausibility

We compared the magnitude of the hindsight bias in individuals and groups with the prediction that the plausibility of an outcome would affect the magnitude of the group–individual difference. We provided groups and individuals with outcomes of scientific studies, and asked them to predict the probability of those outcomes as if they did not know the given outcomes and to report their level of surprise at the outcomes. Overall, groups were more prone to hindsight bias than were individuals, but the group–individual difference was present only when the given outcomes were relatively implausible (Study 1). Moreover, this difference was not eliminated even when participants were asked to consider alternative outcomes (Study 2). Implications are discussed.

Picture This: The Influence of Emotionally Valenced Images,On Attention,Selection, and Sharing of Social Media News

Social media platforms have become the primary conduits to news for many consumers, yet little is known about how the content in social media posts is viewed and evaluated by consumers or how it shapes their decisions about selecting and sharing this information. A within-subjects eye-tracking experiment (N = 60), was conducted to examine the influence of image presence and valence on attention to and engagement with news stories on social media. Participants viewed a series of 29 social media posts of news stories, each of which was either paired with no image, a positively valenced image, or a negatively valenced image. Participants attention to the images was captured via eye tracking, and they answered dependent measures to gauge level of emotion and arousal, and intention to click and share. The results show that posts containing positive images elicited a higher level of visual attention than those with negative or no images, which led to higher intentions to click and share posts with positive images. The results provide a deeper understanding of the importance of images in driving news consumption, and offer practical implications for journalists, news organizations and groups using social media to spread a message.     

Development of a puff- and suction-type pressure stimulator for human tactile studies

In this study, we developed a tactile stimulator capable of administering either puff- or suction-type stimuli. The system is composed of three parts: a control unit, an air-handling unit, and a stimulation unit. The control unit controls the type, intensity, and time of stimulation. The air-handling unit delivers the stimulation power quantitatively to the stimulation unit, as commanded by the control unit. The stimulation unit stably administers either type of pressure to the skin, without any change of the tactor. Although the design of the stimulator is simple, it allows for five levels of control of the stimulation intensity (2–6 psi) and 0.1-s steps of control of the stimulation time, as we confirmed by tests. Preliminary electroencephalographic and event-related potential (ERP) studies of our system in humans confirmed the presence of N100 and P300 waves at standard electrode position C3, which are related to perception and cognition, respectively, in the somatosensory area of the brain. In addition, different stimulation types (puff and suction) and intensities (2 and 6 psi) were reflected in different peak-to-peak amplitudes and slopes of the mean ERP signal. The system developed in this study is expected to contribute to human tactile studies by providing the ability to administer puff- or suction-type stimuli interchangeably.     

Differentiation of Self,Interpersonal Conflict,and Depression: The Mediating Role of Anger Expression

The current study investigated how differentiation of self (Bowen in Family therapy in clinical practice. Jason Aronson, New York, 1978; Kerr and Bowen in Family evaluation. W. W. Norton and Company, New York, 1988) was related to interpersonal conflict and depression, and tested mediation hypotheses involving anger expression. The results revealed that anger expressed outwardly partially mediated the relationship between emotional reactivity and interpersonal conflict, and that anger expressed inwardly fully mediated the relationship between emotional cutoff and depression among 260 college students attending an urban university located in Midwestern United States.     

Evidentiality in language and cognition

What is the relation between language and thought? Specifically, how do linguistic and conceptual representations make contact during language learning? This paper addresses these questions by investigating the acquisition of evidentiality (the linguistic encoding of information source) and its relation to children's evidential reasoning. Previous studies have hypothesized that the acquisition of evidentiality is complicated by the subtleness and abstractness of the underlying concepts; other studies have suggested that learning a language which systematically (e.g. grammatically) marks evidential categories might serve as a pacesetter for early reasoning about sources of information. We conducted experimental studies with children learning Korean (a language with evidential morphology) and English (a language without grammaticalized evidentiality) in order to test these hypotheses. Our experiments compared 3- and 4-year-old Korean children's knowledge of the semantics and discourse functions of evidential morphemes to their (non-linguistic) ability to recognize and report different types of evidential sources. They also compared Korean children's source monitoring abilities to the source monitoring abilities of English-speaking children of the same age. We found that Korean-speaking children have considerable success in producing evidential morphology but their comprehension of such morphology is very fragile. Nevertheless, young Korean speakers are able to reason successfully about sources of information in non-linguistic tasks; furthermore, their performance in these tasks is similar to that of English-speaking peers. These results support the conclusion that the acquisition of evidential expressions poses considerable problems for learners; however, these problems are not (necessarily) conceptual in nature. Our data also suggest that, contrary to relativistic expectations, children's ability to reason about sources of information proceeds along similar lines in diverse language-learning populations and is not tied to the acquisition of the linguistic markers of evidentiality in the exposure language. We discuss implications of our findings for the relationship between linguistic and conceptual representations during development.     

Social capital,acculturation attitudes,and sociocultural adaptation of migrants from central Asian republics and South Korea in Russia

This research examines the relationship of social capital with the acculturation attitudes and sociocultural adaptation of 122 migrants from Central Asian republics of the former Union of Soviet Socialist Republics (Uzbekistan, Tajikistan, Turkmenistan, Kyrgyzstan, and Kazakhstan) and 136 migrants from South Korea. The questionnaire included scales for assessing acculturation attitudes (integration, assimilation, and separation), individual social capital (bridging and bonding), and sociocultural adaptation. Using parallel mediation analysis, we found that acculturation attitudes for migrants from Central Asia are secondary to their social capital in relation to sociocultural adaptation. However, among migrants from South Korea, social capital is not linked to their acculturation attitudes, and in general, its role in sociocultural adaptation is lower as compared to the role of acculturation attitudes. As a whole, our research shows that although sociocultural adaptation for all ethnic groups is linked to acculturation attitudes and social capital, acculturation attitudes for certain ethnic groups can be dependent on social capital.
