    Parental use of spatial language and gestures in early childhood
    (Wiley, 2019) Department of Psychology; Göksun, Tilbe; Kısa, Yağmur Deniz; Erciyes, Aslı Aktan; Turan, Eylül; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 47278; N/A; N/A; N/A
    Parents' use of spatial language and gestures is closely linked to children's spatial language development. Little is known about the quantity and quality of early spatial input and how infants' individual characteristics may be related to the spatial input they receive. Here, we examine (1) the amount and type of spatial input 16- to 21-month-old Turkish-learning children (n = 34) received in the context of a spatial activity (puzzle play) and (2) whether parental spatial input in the form of speech and gesture varies based on children's age, sex, and early spatial vocabulary comprehension assessed in an earlier session. Results of the regression analyses showed that parents' use of spatial words was predicted by children's age over and beyond earlier spatial word comprehension and sex. In particular, parents used more spatial speech as their children got older even in this restricted age range. Children's early spatial word comprehension also correlated with parents' spatial word production. Yet, parents' overall gesture use and gestures with spatial words were not predicted by children's age, sex, or early spatial word comprehension. These findings suggest that in the spatial domain, early verbal input, but not gestural input, can change depending on children's age and children's spatial vocabulary comprehension may also be related to parental use of later spatial language. Statement of contribution What is already known on this subject? Parents enhance their children's spatial skills using spatial language and gestures. Parental spatial talk is related to children's later spatial skills. What does this study add? We assess both spatial talk and gesture in early childhood. We examine the children's characteristics (age, sex) in relation to spatial talk and gesture. We present how children's earlier vocabulary competence relates to parental input.

    Dilation and constriction of subjective time based on observed walking speed
    (Frontiers, 2018) Department of Psychology; Karşılar, Hakan; Kısa, Yağmur Deniz; Balcı, Fuat; Faculty Member; Department of Psychology; Graduate School of Social Sciences and Humanities; N/A; N/A; 51269
    The physical properties of events are known to modulate perceived time. This study tested the effect of different quantitative (walking speed) and qualitative (walking-forward vs. walking-backward) features of observed motion on time perception in three complementary experiments. Participants were tested in the temporal discrimination (bisection) task, in which they were asked to categorize durations of walking animations as "short" or "long." We predicted the faster observed walking to speed up temporal integration and thereby to shift the point of subjective equality leftward, and this effect to increase monotonically with increasing walking speed. To this end, we tested participants with two different ranges of walking speeds in Experiment 1 and 2 and observed a parametric effect of walking speed on perceived time irrespective of the direction of walking (forward vs. rewound forward walking). Experiment 3 contained a more plausible backward walking animation compared to the rewound walking animation used in Experiments 1 and 2 (as validated based on independent subjective ratings). The effect of walking-speed and the lack of the effect of walking direction on perceived time were replicated in Experiment 3. Our results suggest a strong link between the speed but not the direction of perceived biological motion and subjective time.
