The objective of this work was to investigate the effects of auditory and visuo-spatial secondary tasks on variability in lane position in predictable and unpredictable driving conditions. Sixty-six participants drove a simulated vehicle. Predictability was manipulated by adding wind gusts, and the secondary task load by either an auditory task (Experiment 1) or a visuo-spatial task (Experiment 2). Results demonstrated that in the predictable driving condition, lane position variability decreased when auditory secondary task load was given, but it was not affected by visuo-spatial secondary task load. In the unpredictable driving condition; however, while the auditory secondary task load did not affect lane position variability, visuo-spatial secondary task load increased it. The data suggests that the effects of cognitive load on lane maintenance may depend on the type of the secondary task beside predictability of primary task.

The Effects of auditory and visuo-spatial secondary tasks on lane maintenance in predictable and unpredictable driving conditions Özbozdağlı, Seda; Mısırlısoy, Mine; Özkan, Türker; Department of Psychology (2015) The present study investigated the effects of auditory and visuo-spatial secondary tasks on variability in lane position in predictable and unpredictable driving conditions. The study also aimed to explore the impacts of perceived driving skills and safety skills on driving performance. Sixty-six participants filled out the Driver Skill Inventory and drove a simulated vehicle. Predictability was manipulated by adding wind gusts and secondary task load was manipulated by an auditory delayed digit recall n-ba...
EFFECT OF CONCURRENT FEEDBACK AND POSTURAL TASK DIFFICULTY ON POSTURAL CONTROL TAŞCI, SEDA; Kirazcı, Sadettin; Çelik, Hüseyin; Department of Physical Education and Sports (2022-9) Studies investigating the effect of concurrent feedback reported inconsistent results, especially on motor tasks with different difficulties. There is also lack of studies examining the effects of concurrent feedback on postural tasks with different difficulties. To fill this gap, this study investigated the effect of concurrent visual feedback (CVF) and postural task difficulty (PTD) on postural control in acquisition and retention phases. Participants were 40 university students who were randomly allocate...
Eş zamanlı gerçekleştirilen bilişsel ve motor görevin postür kontrolü üzerine etkisi Babajimopoulos, Zeren; Yılmaz, Uğur; Arpınar Avşar, Pınar; Kirazcı, Sadettin (2018-11-03) Amaç:Bu çalışmanın amacı farklı zorlukta postural motor görev sırasında eş zamanlı olarak gerçekleştirilen bilişsel görevin postür kontrolü üzerine etkisinin incelenmesidir. Yöntem:19 gönüllü katılımcı (yaş:23±6 yıl, boy:171.7± cm, v.ağırlığı:71.1± kg) 1 dk boyunca üç farklı zorluk düzeyinde bilişsel görev altında, kuvvet platformu üzerinde ayakta sakin duruş (QS) ve istemli postural salınım (VS) hareketi yapmaları istenmiştir. Bilişsel görev işitsel olarak kendilerine ardışık olarak sunulan basit aritmetik...
Effect of individualized cognitive and postural task difficulty levels on postural control during dual task condition Gursoy, Zeren G.; Yilmaz, Ugur; ÇELİK, HÜSEYİN; Arpinar-Avsar, Pinar; Kirazcı, Sadettin (2022-07-01) © 2022 Elsevier B.V.Background: Previous dual task studies suggested that the difficulty of the concurrent cognitive and motor tasks may not be challenging to the same degree for each person. This study approaches this problem by setting individualized difficulty levels for tasks to examine the dual task interference. Research question: Do the features of postural sway depend on increased individualized difficulty levels of concurrent cognitive and postural activities? Methods: 20 young healthy participants...
The Combined Effect of Light Touch and Cognitive Task Difficulty on Postural Control çelik, tuğba; Kirazcı, Sadettin; Department of Physical Education and Sports (2021-10-12) Studies investigating combined effects of light touch and cognitive task are limited and available results are inconsistent regarding effects of cognitive task on postural control. Therefore, this study investigated the combined effects of light touch and cognitive task difficulty on postural control. Participants performed cognitive task and light touch individually and simultaneously. Results indicated that both light touch and cognitive task improved postural sway individually. The cognitive task difficu...
