However, there is also evidence of an age-related positivity effect, with negativity bias generally fading with age. With the rise of COVID-19 cases, older adults (aged 55 years and older) who consume media frequently are at a high risk for declining mental health. To date, there has been no research on the positivity vs. negativity bias of media news on older adults. Here, we investigated whether positivity or negativity bias plays a larger role in affecting how older adults react to COVID-19 news. Methods: Sixty-nine older adults (aged 55–95) answered questions about their weekly media consumption and how closely they followed news relating to COVID-19. They also completed a general health questionnaire. They were then randomly assigned to read either positive or negative COVID-19 news (n = 35 and 34, respectively). The adults w...

While there is mounting evidence suggesting that bilingualism confers advantages in domain-general cognitive abilities in late adulthood (see Bialystok, 2017, for a review), few studies have investigated the influences of bilingualism on socio-cognitive abilities such as theory of mind (ToM) in the normal aging process. Thus, in this study, we examine how bilingualism factors (i.e., onset age of bilingualism, language balance, and diversity in language use) are associated with individual differences in ToM in healthy older adult bilinguals aged 58-79 (N=44). ToM abilities were assessed using the Theory-of-Mind Task Battery (Hutchins et al., 2008), where participants viewed vignettes and answered questions about the protagonists’ cognitive and affective mental states. All participants completed a self-report language backgro...

Recent work suggests that even preschool-aged children are sensitive to what others think of the self and actively attempt to manage these beliefs (Asaba & Gweon, 2018). What cognitive capacities underlie these early self-presentational behaviors, and in what contexts do these behaviors emerge? Here we show that preschoolers strategically demonstrate their competence to even a puppet, but only when an adult treats the puppet as an agent and specifically asks which toy the child wants to “show” to the puppet (Exp.1). However, they do not show such strategic demonstration of their competence when the same puppet is treated as an object (Exp.2). These results suggest that selfpresentational behaviors can emerge even in the absence of any immediate prospect of social evaluation insofar as children consider the target entity as capable of holding beliefs. Furthermore, whether or not children as...

No studies have demonstrated that the dual-language control process directly contributes to the bilingual cognitive advantage. We utilized a novel language control manipulation paradigm where 83 English-Chinese bilingual adults completed a reading and comprehension task in either singlelanguage (low-language-control) or dual-language (highlanguage-control) prior to performing nonverbal executive control tasks (Stroop, task-switching, and n-back). Results showed that language control had significant effects on subsequent cognitive performance, depending on whether the participants were regular dual language users or not. In the dual-language condition, but not the single-language condition, participants who used both languages regularly demonstrated a smaller mixing cost in task-switching and a greater sensitivity in n-back detection compared to participants who ...

Six-month-olds, for example, would follow the direction of an adult’s gaze to an object in the presence of complementary signals such as eye contact and infant-directed speech (Senju & Csibra, 2008). By the end of the first year, infants begin to understand human gaze and pointing as social and goal-directed actions (Beier & Spelke, 2012; Senju, Csibra, & Johnson, 2008; Woodward, 2003), while older toddlers and preschoolers are able to use social cues to identify referential mappings in social learning contexts, demonstrating a better understanding of the communicative intention of these social cues (Behne, Carpenter, & Tomasello, 2005; Berman, Chambers, & Graham, 2010; Jaswal, 2004). Children also re...

The current study examined whether children rely on cues to informant credibility (i.e., history of accuracy) to determine if they would endorse an unexpected label from an informant. Threeand 4-year-olds (N = 60) saw a picture of a hybrid artifact that consisted of features of two typical familiar artifacts. Children made initial judgments about the name of the hybrid object and subsequently received a different name offered by an informant who had earlier either accurately or inaccurately named familiar objects. Children were more willing to revise their own judgment and accept the unexpected label if it was from a previously accurate informant than if it was from someone who had made obvious naming errors. This suggests that preschool-aged children selectively revise their own knowledge; they are more trusting toward sources proven accurate than inaccurate.

Due to the lack of GPS positioning accuracy in indoor, sheltered, and high rise building environments, we rely on widely available WiFi access points (AP) in contemporary urban areas to accurately identify POI and mobility patterns, by comparing the similarity in the WiFi measurements. We propose a system architecture to scan the surrounding WiFi AP, and perform unsupervised learning to demonstrate that it is possible to identify three major insights, namely the indoor POI within a building, neighborhood activity, and micro mobility of the users. Our results show that it is possible to identify the aforementioned insights, with the fusion of WiFi and GPS, which are not possible to identify by only using GPS.

By using k-medoids clustering, we identified eight demographic resident segments, and using a multi-perspective approach with k-means, we identified their place preferences in terms of place visit frequency, and place indication. Shopping Mall, Eateries, and Market have found to be the most popular places in terms of visit frequency. In terms of place indication, our results show that segments from different age groups have a difference in their preference for certain place types. Moreover, we identified town based characteristics in place preference through our analysis.
