Publication Metadata only Sequence of theory-of-mind acquisition in Turkish children from diverse social backgrounds(Wiley, 2018) Brink, Kimberly A.; Wellman, Henry M.; Department of Psychology; N/A; Selçuk, Bilge; Ekerim-Akbulut, Müge; Faculty Member; PhD Student; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 52913; 311454We examined the sequence of theory of mind (ToM) acquisition in 260 Turkish children (M-age=53.36months, SD=10.37) and the demographic factors associated with it. Children came from 5 different cities in Turkey. Their ToM skills were measured using ToM Scale, which probes various mental state understandings from diverse desires to hidden emotions. These Turkish children demonstrated the traditional, collectivist ToM acquisition pattern evident in Iran and China with earlier understanding of knowledge access than diverse beliefs, not the western, individualist pattern evident in the United States, Australian, and German children. Gender, socio-economic status (SES), and number of adults living in the home influenced the pace of children's ToM acquisitions. A post hoc analysis examined a minority of children that exhibited individualist ToM acquisition with earlier achievement of diverse beliefs than knowledge access. The results contribute to a fuller sociocultural understanding of ToM development including examination of variations within a single heterogeneous developing country. They also further suggest the importance of exposure to different ideas and beliefs in large households for earlier understanding of varying belief states. Highlights We assessed theory of mind (ToM) acquisition in 260 Turkish children whose families spanned a large range of social class circumstances. We measured ToM via Wellman and Liu's scale (2004), consisting of five items testing diverse desires, diverse belief, knowledge access, false belief, and hidden emotion. The Turkish children demonstrated the traditional, collectivist ToM acquisition pattern, but a minority of children exhibited individualistic ToM acquisition. In cultures where elements of individualism and collectivism are blended, children can come to different orders of acquisition in accord with recent arguments that cultural development often represents a coexistence of different reasoning styles.Publication Metadata only Learning deep temporal representations for fMRI brain decoding(Springer International Publishing Ag, 2015) Firat, Orhan; Aksan, Emre; Fatos T. Yarman; Department of Psychology; Öztekin, İlke; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; N/AFunctional magnetic resonance imaging (fMRI) produces low number of samples in high dimensional vector spaces which is hardly adequate for brain decoding tasks. In this study, we propose a combination of autoencoding and temporal convolutional neural network architecture which aims to reduce the feature dimensionality along with improved classification performance. The proposed network learns temporal representations of voxel intensities at each layer of the network by leveraging unlabeled fMRI data with regularized autoencoders. Learned temporal representations capture the temporal regularities of the fMRI data and are observed to be an expressive bank of activation patterns. Then a temporal convolutional neural network with spatial pooling layers reduces the dimensionality of the learned representations. By employing the proposed method, raw input fMRI data is mapped to a low-dimensional feature space where the final classification is conducted. In addition, a simple decorrelated representation approach is proposed for tuning the model hyper-parameters. The proposed method is tested on a ten class recognition memory experiment with nine subjects. Results support the efficiency and potential of the proposed model, compared to the baseline multi-voxel pattern analysis techniques.Publication Metadata only Exploring projection based mixed reality with tangibles for nonsymbolic preschool math education(Assoc Computing Machinery, 2019) N/A; N/A; Department of Psychology; Department of Media and Visual Arts; Department of Electrical and Electronics Engineering; Salman, Elif; Beşevli, Ceylan; Göksun, Tilbe; Özcan, Oğuzhan; Ürey, Hakan; Master Student; Researcher; Faculty Member; Faculty Member; Faculty Member; Department of Psychology; Department of Media and Visual Arts; Department of Electrical and Electronics Engineering; Graduate School of Sciences and Engineering; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Engineering; N/A; N/A; 47278; 12532; 8579A child's early math development can stem from interactions with the physical world. Accordingly, current tangible interaction studies focus on preschool children's formal (symbolic) mathematics, i.e. number knowledge. However, recent developmental studies stress the importance of nonsymbolic number representation in math learning, i.e. understanding quantity relations without counting(more/less). To our knowledge, there are no tangible systems based on this math concept. We developed an initial tangible based mixed-reality(MR) setup with a small tabletop projector and depth camera. Our goal was observing children's interaction with the setup to guide our further design process towards developing nonsymbolic math trainings. In this paper we present our observations from sessions with four 3-to-5 year old children and discuss their meaning for future work. Initial clues show that our MR setup leads to exploratory and mindful interactions, which might be generalizable to other tangible MR systems for child education and could inspire interaction design studies.Publication Metadata only From crime and punishment to empathy and acceptance: family therapy training and supervision with Turkish juvenile probation officers(Taylor and Francis, 2019) Department of Psychology; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 222027The first offense of the youth indicates an underlying unresolved issue in the family system and the youth involved in crime is the symptom carrier. Probation officers need to work with youth to identify their needs for further resources to prevent future crime. For Ahmet, crime emerged as a way of connecting with his uncle; it was a shared experience that made him feel connected to a family member. Although crime was dysfunctional and harmful, it had an emotional and a relational meaning for Ahmet. In the eyes of the family, Ayse was not a motivated idealistic helper, nor was she their ally. They perceived Ayse simply as another representative of the state, an officer, and a symbol of institutional punishment. The beauty of family therapy is to collect broken pieces of hearts of family members and heal them through hope, connection, loyalty, trust, acknowledgment, and empathy.Publication Metadata only Linguistic strategies serving evaluative functions: a comparison between Japanese and Turkish narratives(Lawrence Erlbaum Associates. Inc., 2003) Nakamura, Keiko; Department of Psychology; Küntay, Aylin C.; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 178879N/APublication Metadata only Acculturation and family relations(Türk Psikologlar Derneği, 2014) Department of Psychology; Kağıtçıbaşı, Çiğdem; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; N/AThis article is an overview of some of the main issues seen in the context of immigration. As an epilogue, it relates to the other articles in this Special Issue, as well. In particular, the European scene is examined on the basis of research conducted over the last decades. There is also an emphasis on family relations and acculturation as well as their interface. Immigration and acculturation over half a century are introduced through a historical perspective noting that multiphasic and multidisciplinary approaches are needed to understand the myriad factors involved. In particular, cultural and developmental viewpoints are promising. Acculturation research has focused on the acculturating migrant, without due attention to the context of acculturation. In particular, prejudice and discrimination are the greatest challenges. This approach leaves something to be desired, since immigration is a very complex human phenomenon involving issues ranging from micro to macro levels of analysis. While the former concerns individual factors, including the family, the latter includes historic, sociological, economic, and legal aspects and applications. Focusing on the acculturating (or non-acculturating) individual or family without a contextual approach can lead to dispositional attributions, even ‘blaming the victim’, that is, social psychological processes not conducive to understanding and promoting the well-being of the immigrant or the host society. In this context, there is a further need for research to address policies and to suggest solutions for improvement. In particular, concerted efforts that prove to be beneficial for the family, women and children are badly needed. Turkish psychologists and social scientists would do well to attend to these very important topics of study. / Bu makale göç olgusunun çeşitli yönlerine eğilen genel bir çalışmadır ve bu özel sayı için bir sonsöz niteliği taşımaktadır. Özellikle son birkaç on yıldaki araştırmalardan yola çıkarak, bu özel sayıdaki makaleler de dahil olmak üzere, Avrupa’daki durumu ele almaktadır. Aynı zamanda kültürleşme ve aile konularını ve bunların etkileşimini inceler. Yarım yüzyıllık bir göç olgusu tarihsel bir perspektifle ele alınıyor. Bu çok faktörlü karmaşık olayı iyi anlayabilmek için çok katmanlı ve çok disiplinli bir yaklaşımın gerekli olduğu da not ediliyor. Özellikle kültürel ve gelişimsel yaklaşımların yararlı olacağı öne sürülüyor. Kültürleşme çalışmaları genellikle kültürleşme ortamını yeterince incelemeden kültürleşen göçmene vurgu yapıyor. Oysa ki baskın toplumdaki önyargı ve ayrımcılık önemli sorunlardır. Bu yaklaşım yetersiz kalıyor çünkü karmaşık göç süreci, mikro yaklaşımlardan, makro yaklaşımları gerekli kılan karmaşık bir olgudur. Mikro düzeyde insan ve aileye yönelik araştırmalar söz konusuyken, makro düzeyde sosyolojik, ekonomik, hukuksal hususların ve uygulamaların incelenmesi önemlidir. Bağlamı dikkate almadan, kültürleşen (ya da kültürleşmeyen) birey ya da aileye vurgu yapmak, içsel atıflara, hatta “mazlumu suçlamaya” kadar gidebilir. Bunlar ise, olayı anlamaya ve gerek göçmenin, gerek baskın toplumun yararına olmayan sosyal psikolojik yaklaşımlardır. Bu noktada araştırmaların göçmen politikalarına yönelik ve çözüm önerici olması çok yararlıdır. Özellikle, göçmen kadın, aile ve çocukların esenliğine katkıda bulunabilecek çabalara ihtiyaç vardır. Türk psikologlar ve sosyal bilimcilerin bu çok önemli araştırma konularına daha fazla eğilmesi çok yararlı olacaktır.Publication Metadata only Monolingual and bilingual children's resolution of referential conflicts: effects of bilingualism and relative language proficiency(Elsevier Science Inc, 2017) Verhagen, Josje; Grassmann, Susanne; Department of Psychology; Küntay, Aylin C.; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 178879Monolingual children follow pointing over labeling when these are in conflict in object selection tasks. Specifically, when a speaker labels one object, but points at another object, monolinguals select the object pointed at. Here, we ask whether (i) bilingual children show the same behavior as monolinguals and (ii) relative language proficiency affects bilinguals' conflict resolution. 35 monolingual and 32 bilingual two- to four-year-olds performed an experiment involving a conflict between pointing and labeling. The bilinguals were tested in Dutch and in English. The bilinguals had a stronger preference for pointing over labeling and selected both objects less often than the monolinguals. Point following was stronger in the bilinguals' weaker language than in their stronger language. These results support earlier findings on bilinguals' increased sensitivity to socio-pragmatic cues and weaker reliance on mutual exclusivity, and show that previously acquired language knowledge affects how children weigh socio-pragmatic and lexical cues.Publication Metadata only Erratum: learning to use demonstratives in conversation: what do language specific strategies in Turkish reveal? (vol 33, pg 303, 2006)(Cambridge Univ Press, 2006) N/A; Department of Psychology; Department of Psychology; Küntay, Aylin C.; Özyürek, Aslı; Faculty Member; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; College of Social Sciences and Humanities; 178879; N/AN/APublication Metadata only TNF-alpha inhibition prevents cognitive decline and maintains hippocampal BDNF levels in the unpredictable chronic mild stress rat model of depression(Elsevier, 2015) Şahin, Tuğce Demirtaş; Karson, Ayşe; Yazır, Yusufhan; Bayramgürler, Dilek; Utkan, Tijen; Department of Psychology; Balcı, Fuat; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 51269Previous findings have shown that patients with depression express higher levels of proinflammatory cytokines such as TNF-alpha and IL-6. We have recently found that Infliximab (a TNF-alpha inhibitor) decreased anhedonia and despair-like behavior in the rat unpredictable chronic mild stress (UCMS) model of depression suggesting that inflammation might play an important role in depression. An increasing number of studies suggest that inflammation is also associated with cognitive impairments. The current study aimed to investigate the effect of UCMS on the cognitive performance of rats and their hippocampal BDNF levels and the effect of chronic Infliximab (5 mg/kg/weekly, i.p.) treatment on these measures. Rats were subjected to different types of stressors daily for a period of 56 days to induce depression-like state. The UCMS resulted in impairments in spatial and emotional memory acquisition and retention with no effect on the level of locomotor activity. These behavioral effects of UCMS were accompanied by reduction in the level of BDNF in the CA1 and CA3 regions of the hippocampus. Chronic Infliximab treatment prevented the UCMS-induced cognitive impairments as well as the reduction in the levels of hippocampal brain-derived neurotrophic factor (BDNF). These results suggest that Infliximab improves the spatial and emotional memory impairments induced by chronic stress in rats likely through its effects on hippocampal function by modulating inflammation.Publication Metadata only Elucidating the common basis for task-dependent differential manifestations of category advantage: a decision theoretic approach(Wiley, 2022) N/A; Department of Psychology; Department of Psychology; Akbıyık, Seda; Göksun, Tilbe; Balcı, Fuat; Master Student; Faculty Member; Faculty Member; Department of Psychology; N/A; N/A; Koç University Research Center for Translational Medicine (KUTTAM) / Koç Üniversitesi Translasyonel Tıp Araştırma Merkezi (KUTTAM); Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 47278; 51269Cross-category hues are differentiated easier than otherwise equidistant hues that belong to the same linguistic category. This effect is typically manifested through both accuracy and response time gains in tasks with a memory component, whereas only response times are affected when there is no memory component. This raises the question of whether there is a common generative process underlying the differential behavioral manifestations of category advantage in color perception. For instance, within the framework of noisy evidence accumulation models, changes in accuracy can be readily attributed to an increase in the efficacy of perceptual evidence integration (after controlling for threshold setting), whereas changes in response time can also be attributed to shorter nondecisional delays (e.g., due to facilitated signal detection). To address the latent decision processes underlying category advantage across different behavioral demands, we introduce a decision-theoretic perspective (i.e., diffusion decision model) to categorical color perception in three complementary experiments. In Experiment 1, we collected data from a binary color naming task (1) to determine the green-blue boundary in our sample and (2) to trace how parameter estimates of interest in the model output change as a function of color typicality. In Experiments 2 and 3, we used same-different task paradigms (with and without a memory component, respectively) and traced the category advantage in color discrimination in two parameters of the diffusion decision model: nondecision time and drift rate. An increase in drift rate predominantly characterized the category advantage in both tasks. Our results show that improved efficiency in perceptual evidence integration is a common driving force behind different manifestations of category advantage.
