Effect of cognitive task difficulty on postural control

Gürsoy, Zeren Görkem
Human posture control is accompanied usually in daily life with other tasks, such as cognitive tasks. This thesis is on the effects of cognitive task difficulty on postural control, the postural control mechanisms, attention and its relation to posture control and finally the dual task environments for posture control. The experiment’s set an individualized difficulty level for each participant. Results indicate that when motor and challenging cognitive tasks are completed under dual task conditions, dual task interference was observed.


Effect of individualized cognitive and postural task difficulty levels on postural control during dual task condition

© 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...
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...
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...
The Effect of Context on Small Screen and Wearable Device Users’ Performance - A Systematic Review
Akpınar, Elgin; Yeşilada, Yeliz; Temizer, Selim (Association for Computing Machinery (ACM), 2020-7-5)
Small screen and wearable devices play a key role in most of our daily tasks and activities. However, depending on the context, users can easily experience situationally induced impairments and disabilities (SIIDs). Previous studies have defined SIIDs as a new type of impairment in which an able-bodied user's behaviour is impaired by the context including the characteristics of a device and the environment. This article systematically reviews the empirical studies on the effect of context on SIIDs. In parti...
The Role of Gender and Relative Skills in Task Juggling
Büyükboyacı Hanay, Mürüvvet İlknur (2018-01-01)
In this article, we examine individuals’ multitasking behaviors and how multitasking affects their performance when they are faced with two different tasks and the tasks are complementary, i.e., multitasking is compulsory. First, we find that when individuals are switching between tasks in such an environment, the process of switching is affected by their gender as well as their relative skill in the tasks. In particular, whereas the frequency with which men and women switch between tasks is relatively simi...
