Publication Metadata only Why wait for the verb? Turkish speaking children use case markers for incremental language comprehension(Elsevier, 2019) Özge, Duygu; Snedeker, Jesse; Department of Psychology; Küntay, Aylin C.; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 178879Publication Metadata only Eyewitness memory distortion following co-witness discussion: a replication of Garry, French, Kinzett, and Mori (2008) in ten countries(AMER PSYCHOLOGICAL ASSOC, 2019) Ito, Hiroshi; Barzykowski, Krystian; Grzesik, Magdalena; Janssen, Steve M. J.; Khor, Jessie; Rowthorn, Harriet; Wade, Kimberley A.; Luna, Karlos; Albuquerque, Pedro B.; Kumar, Devvarta; Singh, Arman Deep; Cecconello, William Weber; Cadavid, Sara; Laird, Nicole C.; Baldassari, Mario J.; Lindsay, D.

(2008) by testing participants from 10 countries (Brazil, Canada, Colombia, India, Japan, Malaysia, Poland, Portugal, Turkey, and the United Kingdom; total N=486). Pairs of participants sat beside each other, viewing different versions of the same movie while believing that they viewed the same version. Later, participant pairs answered questions collaboratively, which guided them to discuss conflicting details. Finally, participants took a recognition test individually. Each of the 10 samples replicated the Garry et al. finding: Participants often reported on the final test a non-witnessed answer that their co-witness had stated during the collaboration phase. Such co-witness suggestibility errors were especially likely when the witness had not disputed the co-witness's report during the collaboration phase. The results demonstrate the replicability and generalizability of the co-witness suggestibility effect.Publication Metadata only Insulin resistance, obesity and lipotoxicity(Springer, 2017) Dereli, Dilek Yazıcı; Sezer, Havva; Faculty Member; Teaching Faculty; School of Medicine; School of Medicine; 179659; 154807Lipotoxicity, originally used to describe the destructive effects of excess fat accumulation on glucose metabolism, causes functional impairments in several metabolic pathways, both in adipose tissue and peripheral organs, like liver, heart, pancreas and muscle. Lipotoxicity has roles in insulin resistance and pancreatic beta cell dysfunction. Increased circulating levels of lipids and the metabolic alterations in fatty acid utilization and intracellular signaling, have been related to insulin resistance in muscle and liver. Different pathways, like novel protein kinase c pathways and the JNK-1 pathway are involved as the mechanisms of how lipotoxicity leads to insulin resistance in nonadipose tissue organs, such as liver and muscle. Mitochondrial dysfunction plays a role in the pathogenesis of insulin resistance. Endoplasmic reticulum stress, through mainly increased oxidative stress, also plays important role in the etiology of insulin resistance, especially seen in non-alcoholic fatty liver disease. Visceral adiposity and insulin resistance both increase the cardiometabolic risk and lipotoxicity seems to play a crucial role in the pathophysiology of these associations.Publication Metadata only Social factors in bird-song development: learning to sing with friends and rivals(Springer, 2021) Beecher, Michael D.; Department of Psychology; Akçay, Çağlar; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 272053Laboratory studies have revealed that social factors are key in bird-song learning. Nevertheless, little is known about how or why birds choose the songs they do learn from the many they will hear under natural conditions. We focus on various theories concerning social song learning that have been offered to date, with special attention paid to two axes of social factors. First, does song learning occur via direct interaction of the young bird with song tutors, or via social eavesdropping by the young bird on interacting singers (social modeling of song)? Social modeling, a hypothesis first proposed by Pepperberg (Zeitschrift fur Tierpsychologie, 55(2), 139-160,1981), and direct interaction are not mutually exclusive hypotheses, and the evidence we review suggests both play a role in song learning. Second, does song learning occur via interactions with rivals (territorial competitors) or with friends (mutually tolerant or even cooperative territorial neighbors). These are largely mutually exclusive hypotheses, and can really only be tested in the field. There is little evidence on this contrast to date. We review our recent study on song sparrows, which indicates that both the young bird and his primary tutor may benefit from song learning/tutoring. If this mutual benefit result is confirmed by further studies, we believe that song "tutoring" in these cases may be more than a term of convenience: that it may qualify as true teaching.Publication Metadata only Spontaneous gesture and spatial language: evidence from focal brain injury(2015) Lehet, Matthew; Malykhina, Katsiaryna; Chatterjee, Anjan; Department of Psychology; Göksun, Tilbe; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 47278People often use spontaneous gestures when communicating spatial information. We investigated focal brain-injured individuals to test the hypotheses that (1) naming motion event components of manner-path (represented by verbs-prepositions in English) are impaired selectively, (2) gestures compensate for impaired naming. Patients with left or right hemisphere damage (LHD or RHD) and elderly control participants were asked to describe motion events (e.g., running across) depicted in brief videos. Damage to the left posterior middle frontal gyrus, left inferior frontal gyrus, and left anterior superior temporal gyrus (aSTG) produced impairments in naming paths of motion; lesions to the left caudate and adjacent white matter produced impairments in naming manners of motion. While the frequency of spontaneous gestures were low, lesions to the left aSTG significantly correlated with greater production of path gestures. These suggest that producing prepositions-verbs can be separately impaired and gesture production compensates for naming impairments when damage involves left aSTG. (C) 2015 Elsevier Inc.

Nations had varying levels of morbidity and mortality and adopted different measures to prevent the spread of infection. Effects of the pandemic on spontaneous (rather than voluntary) past and future thoughts remain unexplored. Here, we report data from a multicountry online study examining how both country- and individual-level factors are associated with this core aspect of human cognition. Results showed that national (stringency of measures) and individual (attention to COVID-related information and worry) factors separately and jointly predicted the frequency of people's pandemic-related spontaneous thoughts. Additionally, no typical positivity biases were found, as both past and future spontaneous thoughts had a negative emotional valence. This large-scale multinational study provides novel insights toward better understanding the emergence and qualities of spontaneous past and future thoughts. Findings are discussed in terms of the determinants and functions of spontaneous thought. General Audience Summary The COVID-19 pandemic was a global phenomenon; people in countries across the world experienced the pandemic similarly, but did it affect the way we perceived the past and future? This study reports whether and how people experienced spontaneous thoughts about the past and future of the pandemic-that is, images of the past or future that appear in mind without warning and with little effort (e.g., remembering a recent lockdown or imagining a future announcement)-during the pandemic's first wave. Spontaneous past and future thoughts are important in daily life and can indicate poor mental health when negative in nature. Here, for the first time, we asked people from 14 different countries across four continents to report the frequency and emotional characteristics of their spontaneous past and future pandemic-related thoughts in the first wave of the pandemic. The study showed that the national context (in particular, COVID regulations) predicted the frequency of people's spontaneous thoughts about the pandemic. Emotional aspects of these thoughts were predicted by individual factors such as isolation, worry, attention to COVID-related information, and impact of COVID-19 on everyday life, in addition to national factors. Finally, in contrast to previous research showing a "positive bias," which is thought to be beneficial, past and future spontaneous pandemic-related thoughts had a negative emotional tone. This study allowed us to demonstrate that the tendency to experience spontaneous thoughts about an ongoing international event can be predicted by societal context, which may be valuable for examining the social predictors of spontaneous emotional thoughts about the past and future. The study also characterized the negative tone of past and future spontaneous thoughts about the pandemic, and future studies will be needed to examine the longer term consequences of these effects.Publication Metadata only Early language-specificity of children's event encoding in speech and gesture: evidence from caused motion in Turkish(Taylor & Francis, 2014) Furman, Reyhan; Department of Psychology; Department of Psychology; Özyürek, Aslı; Küntay, Aylin C.; Faculty Member; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 178879Previous research on language development shows that children are tuned early on to the language-specific semantic and syntactic encoding of events in their native language. Here we ask whether language-specificity is also evident in children's early representations in gesture accompanying speech. In a longitudinal study, we examined the spontaneous speech and cospeech gestures of eight Turkish-speaking children aged one to three and focused on their caused motion event expressions. In Turkish, unlike in English, the main semantic elements of caused motion such as Action and Path can be encoded in the verb (e. g. sok-'put in') and the arguments of a verb can be easily omitted. We found that Turkish-speaking children's speech indeed displayed these language-specific features and focused on verbs to encode caused motion. More interestingly, we found that their early gestures also manifested specificity. Children used iconic cospeech gestures (from 19 months onwards) as often as pointing gestures and represented semantic elements such as Action with Figure and/or Path that reinforced or supplemented speech in language-specific ways until the age of three. In the light of previous reports on the scarcity of iconic gestures in English-speaking children's early productions, we argue that the language children learn shapes gestures and how they get integrated with speech in the first three years of life.Publication Metadata only Cool, but understanding...experiencing cooler temperatures promotes perspective-taking performance(Elsevier, 2013) Sassenrath, Claudia; Sassanberg, Kai; Department of Psychology; Semin, Gün Refik; Researcher; Department of Psychology; College of Social Sciences and Humanities; N/AThe current research examined the impact of temperature cues on perspective-taking. Individuals often start with their own point-of-view when taking another's perspective and thereby unintentionally project their own perspective onto others, which ultimately leads to egocentrically biased inferences of others' perspectives. Accordingly, perspective-taking is enhanced under conditions reducing this egocentric anchoring. In two studies, we show that perspective-taking is enhanced when participants are exposed to cooler rather than warmer temperature cues. Specifically, this is shown to be the case, because cooler temperatures reduce egocentric anchoring in perspective-taking (Study 2). Results are discussed with reference to the literature on (temperature) grounded cognition indicating a link between cold temperatures and social distance. Hence, whereas earlier research has shown that individuals feel more distant from each other when undergoing cooler thermal experiences, the present research suggests that this thermal experience prevents them from over-imputing their own perspectives onto others.

It is an important developmental task to understand the factors contributing to this behavioral divergence for children with advanced ToM understanding, which also has significant practical implications for bullying interventions. We contend that this divergence cannot be explained by a lack of moral competence or empathy, but that the existing evidence lends itself better to a motivational explanation. We propose that the direction of social motivation varies across children and the self versus other oriented social motivation determines if children will use their developed morality and empathy competencies in social interactions to act prosocially or instead cognitively divert moral and empathic emotions to avoid negative feelings about manipulating others. We show how self versus other orientation has been used as a legitimate distinction to inform other domains of psychology and conclude by discussing possible correlates and precursors of this difference in the direction of social orientation in children.Publication Metadata only Lexical richness in maternal input and vocabulary development of Turkish preschoolers in the Netherlands(Springer/Plenum Publishers, 2014) Aarts, Rian; Kurvers, Jeanne; N/A; Vegter, Serpil Demir; Teaching Faculty; N/A; N/AThe present study examined lexical richness in maternal input to Turkish preschool children in the Netherlands and the relationship with their vocabulary. Fifteen Turkish mother-child dyads were videotaped at the age of 3 and 4 in three settings: book reading, picture description and block building. Children's vocabulary in Turkish was measured at the age of 3 and 4 and in Dutch at the age of 5;10. The lexical richness of the input was analysed both quantitatively (tokens) and qualitatively on diversity, density, and sophistication. The results indicate that lexical richness varied largely among mothers, which could partially be attributed to their SES levels and literacy practices. Furthermore, lexical richness differed between the settings, with the highest richness in the book setting. More importantly, lexical richness in maternal input related to the vocabulary of children in L1 (Turkish) and in the longer run also to L2 (Dutch). Quality of the input (diversity, density and sophistication) turned out to be more influential than quantity.
