    Does time extend asymmetrically into the past and the future? a multitask crosscultural study
    (Cambridge University Press (CUP), 2022) Callizo-Romero, Carmen; Tutnjevic, Slavica; Pandza, Maja; Ouellet, Marc; Kranjec, Alexander; Ilic, Sladjana; Gu, Yan; Chahboun, Sobh; Casasanto, Daniel; Santiago, Julio; Department of Psychology; Göksun, Tilbe; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 47278
    Does temporal thought extend asymmetrically into the past and the future? Do asymmetries depend on cultural differences in temporal focus? Some studies suggest that people in Western (arguably future-focused) cultures perceive the future as being closer, more valued, and deeper than the past (a future asymmetry), while the opposite is shown in East Asian (arguably past-focused) cultures. The proposed explanations of these findings predict a negative relationship between past and future: the more we delve into the future, the less we delve into the past. Here, we report findings that pose a significant challenge to this view. We presented several tasks previously used to measure temporal asymmetry (self-continuity, time discounting, temporal distance, and temporal depth) and two measures of temporal focus to American, Spanish, Serbian, Bosniak, Croatian, Moroccan, Turkish, and Chinese participants (total N = 1,075). There was an overall future asymmetry in all tasks except for temporal distance, but the asymmetry only varied with cultural temporal focus in time discounting. Past and future held a positive (instead of negative) relation in the mind: the more we delve into the future, the more we delve into the past. Finally, the findings suggest that temporal thought has a complex underlying structure.

    Do typological differences in the expression of causality influence preschool children's causal event construal?
    (Cambridge University Press (CUP), 2022) Ger, Ebru; Stoll, Sabine; Daum, Moritz M.; Department of Psychology; Küntay, Aylin C.; Göksun, Tilbe; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 178879; 47278
    This study investigated whether cross-linguistic differences in causal expressions influence the mapping of causal language on causal events in three- to four-year-old Swiss-German learners and Turkish learners. In Swiss-German, causality is mainly expressed syntactically with lexical causatives (e.g., asse 'to eat' vs. fuettere 'to feed'). In Turkish, causality is expressed both syntactically and morphologically - with a verbal suffix (e.g., yemek 'to eat' vs. yeDIRmek 'to feed'). Moreover, unlike Swiss-German, Turkish allows argument ellipsis (e.g., 'The mother feeds empty set). Here, we used pseudo-verbs to test whether and how well Swiss-German-learning children inferred a causal meaning from lexical causatives compared to Turkish-learning children tested in three conditions: lexical causatives, morphological causatives, and morphological causatives with object ellipsis. Swiss-German-learning children and Turkish-learning children in all three conditions reliably inferred causal meanings, and did so to a similar extent. The findings suggest that, as young as age 3, children learning two different languages similarly make use of language-specific causality cues (syntactic and morphological alike) to infer causal meanings.

    Artificial bandwidth extension of spectral envelope along a Viterbi path
    (Elsevier, 2013) Department of Computer Engineering; Yağlı, Can; Turan, Mehmet Ali Tuğtekin; Erzin, Engin; Master Student; Faculty Member; Department of Computer Engineering; College of Engineering; N/A; N/A; 34503
    In this paper, we propose a hidden Markov model (HMM)-based wideband spectral envelope estimation method for the artificial bandwidth extension problem. The proposed HMM-based estimator decodes an optimal Viterbi path based on the temporal contour of the narrowband spectral envelope and then performs the minimum mean square error (MMSE) estimation of the wideband spectral envelope on this path. Experimental evaluations are performed to compare the proposed estimator to the state-of-the-art HMM and Gaussian mixture model based estimators using both objective and subjective evaluations. Objective evaluations are performed with the log-spectral distortion (LSD) and the wideband perceptual evaluation of speech quality (PESQ) metrics. Subjective evaluations are performed with the A/B pair comparison listening test. Both objective and subjective evaluations yield that the proposed wideband spectral envelope estimator consistently improves performances over the state-of-the-art estimators. (C) 2012 Elsevier B.V.
