    Putting interaction back into child language: examples from Turkish
    (Sciendo, 2002) Slobin, Dan I.; Department of Psychology; Küntay, Aylin C.; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 178879
    As in the case of other non-English languages, the study of the acquisition of Turkish has mostly focused on aspects of grammatical morphology and syntax, largely neglecting the study of the effect of interactional factors on child morphosyntax. This paper reviews indications from past research that studying input and adult-child discourse can facilitate the study of the acquisition of morphosyntax in the Turkish language. It also provides some recent studies of Turkish child language on the relationship of child-directed speech to the early acquisition of morphosyntax, and on the pragmatic features of a certain kind of discourse form in child-directed speech called variation sets.

    Prevalence and predictors of common mental disorders among Syrian refugees in Istanbul, Turkey: a cross-sectional study
    (Springer, 2020) McGrath, Michael; Roberts, Bayard; Cuijpers, Pim; Sijbrandij, Marit; Sondorp, Egbert; Ventevogel, Pieter; McKee, Martin; Fuhr, Daniela C.; Department of Psychology; Acartürk, Ceren; İlkkurşun, Zeynep; Faculty Member; Master Student; Department of Psychology; College of Social Sciences and Humanities; 39271; N/A
    Purpose: the war in Syria has created the greatest refugee crisis in the 21st century. Turkey hosts the highest number of registered Syrian refugees, who are at increased risk of common mental disorders because of their exposure to war, violence and post-displacement stressors. The aim of this paper is to examine the prevalence and predictors of anxiety, depression, and post-traumatic stress disorder (PTSD) symptoms among Syrian refugees living in Turkey. Methods: a cross-sectional survey of adult Syrian refugees was conducted between February and May 2018 in Istanbul (Sultanbeyli district). Participants (N=1678) were randomly selected through the registration system of the district municipality. The Hopkins Symptoms Checklist (HSCL-25) was used to measure anxiety and depression and the Posttraumatic Stress Disorder (PTSD) Checklist (PCL-5) assessed posttraumatic stress. Descriptive and multivariate regression analyses were used. Results: the prevalence of symptoms of anxiety, depression and PTSD were 36.1%, 34.7% and 19.6%, respectively. Comorbidity was high. Regression analyses identified several socio-demographic, health and post-displacement variables that predicted common mental disorders including: being female, facing economic difficulties, previous trauma experience, and unmet need for social support, safety, law and justice. A lifetime history of mental health treatment and problems accessing adequate healthcare were associated with depression and anxiety but not with PTSD. Conclusions: mental disorder symptoms are highly prevalent among Syrian refugees in Turkey. The association with post-displacement factors points to the importance of comprehensive health and social services that can address these social, economic and cultural stressors.

    Interval timing, dopamine, and motivation
    (Brill, 2014) Department of Psychology; Balcı, Fuat; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 51269
    The dopamine clock hypothesis suggests that the dopamine level determines the speed of the hypothetical internal clock. However, dopaminergic function has also been implicated for motivation and thus the effect of dopaminergic manipulations on timing behavior might also be independently mediated by altered motivational state. Studies that investigated the effect of motivational manipulations on peak responding are reviewed in this paper. The majority of these studies show that a higher reward magnitude leads to a leftward shift, whereas reward devaluation leads to a rightward shift in the initiation of timed anticipatory behavior, typically in the absence of an effect on the timing of response termination. Similar behavioral effects are also present in a number of studies that investigated the effect of dopamine agonists and dopamine-related genetic factors on peak responding. These results can be readily accounted for by independent modulation of decision-thresholds for the initiation and termination of timed responding.
