    Investigation of psychometric properties of Turkish version of nursing students' attitudes and beliefs towards childhood obesity scale
    (W.B. Saunders, 2023) Çelik, Ö.M.; Kudubeş, A.A.; Semerci, Remziye; School of Nursing
    Aim: This study aimed to evaluate the Turkish psychometric properties of The Attitudes and Beliefs of Nursing Students Towards the Childhood Overweight Scale. Methods: The study was conducted with 219 nursing students. The data were obtained with the ‘Information Form’ and the ‘Attitudes and Beliefs of Nursing Students Towards Childhood Overweight. Strengthening the Reporting of Observational Studies in Epidemiology guidelines was implemented in the study. Result: Original scale was created using the Attitudes Towards Obese Person Scale (ATOP) and the Beliefs About Obese Persons Scale (BAOP). ATOP consists of 13 items and two sub-dimensions (self-concept, social relationships) in a 5-point Likert type that evaluates nursing students' attitudes towards childhood obesity. BAOP is 5-point Likert-type and consists of 6 items that evaluate nursing students' beliefs on childhood obesity. When the item-total score correlations were examined in the study, two items showing a negative correlation in the “ATOP” were removed. Cronbach's alpha was 0.80 for the ATOP and 0.83 for the BAOP. In the exploratory EFA and confirmatory CFA factor analyses, the factor loading of all items was >0.40 for both scales. Conclusion: It was determined that Turkish psychometric properties of the Nursing Students' Attitudes and Beliefs towards Childhood Obesity Scales were valid and reliable.

    Memory capacity as the core mechanism of the development of space-time interferences in children
    (Nature Portfolio, 2024) Hallez, Quentin; Department of Psychology; Balcı, Fuat; Department of Psychology; College of Social Sciences and Humanities
    This study investigated the development of spatiotemporal perceptual interactions in 5-to-7 years old children. Participants reproduced the temporal and spatial interval between sequentially presented visual stimuli. The time and spacing between stimuli were experimentally manipulated. In addition, cognitive capacities were assessed using neuropsychological tests. Results revealed that starting at 5 years old, children exhibited spatial biases in their time estimations and temporal biases in their spatial estimations, pointing at space-time interference. In line with developmental improvement of temporal and spatial abilities, these spatiotemporal biases decreased with age. Importantly, short-term memory capacity was a predictor of space-time interference pointing to shared cognitive mechanisms between time and space processing. Our results support the symmetrical hypothesis that proposes a common neurocognitive mechanism for processing time and space.
