In this study, we propose a scheme to investigate the relationship between cognitive tasks and heart beat rate. Accordingly, a video focused on the face was recorded during a working memory experiment. Heart rate was noninvasively estimated from the camera recording. Subsequently, its spectral features were examined. These values were compared with heart rate dynamics obtained from a standard ECG. As a result of the comparison, we observed that the data from the video were compatible with the common heart rhythm, except its spectrum did not have 1/f character.

Prediction of slip in cable-drum systems using structured neural networks KILIÇ, Ergin; Dölen, Melik (SAGE Publications, 2014-02-01) This study focuses on the slip prediction in a cable-drum system using artificial neural networks for the prospect of developing linear motion sensing scheme for such mechanisms. Both feed-forward and recurrent-type artificial neural network architectures are considered to capture the slip dynamics of cable-drum mechanisms. In the article, the network development is presented in a progressive (step-by-step) fashion for the purpose of not only making the design process transparent to the readers but also hig...
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...
Hybrid statistical and machine learning modeling of cognitive neuroscience data Çakar, Serenay; Gökalp Yavuz, Fulya (2023-01-01) The nested data structure is prevalent for cognitive measure experiments due to repeatedly taken observations from different brain locations within subjects. The analysis methods used for this data type should consider the dependency structure among the repeated measurements. However, the dependency assumption is mainly ignored in the cognitive neuroscience data analysis literature. We consider both statistical, and machine learning methods extended to repeated data analysis and compare distinct algorithms ...
Transfer of Learning on a Spatial Memory Task between the Blind and Sighted People AKPINAR, SELÇUK; Popovic, Stevo; Kirazcı, Sadettin (2012-12-01) The purpose of this study was to analyze the effect of two different types of feedback on a spatial memory task between the blind and blindfolded-sighted participants. Participants tried to estimate the predetermined distance by using their dominant hands. Both blind and blindfolded-sighted groups were randomly divided into two feedback subgroups as "100% frequency" and "10% bandwidth". The score of the participants was given verbally to the participants as knowledge of results (KR). The target distance was...
Improvement of temporal resolution of fMRI data for brain decoding Varol, Emel; Yarman Vural, Fatoş Tunay; Department of Computer Engineering (2022-2-10) In this study, we aim to increase the accuracy of the mapping between the states of the brain and problem-solving phases namely planning and execution. To create a computational model to generate the mapping, an fMRI dataset obtained from subjects solving the Tower of London problem has been used. fMRI data is suitable for this problem as it provides regional and time-varying changes in brain metabolism. However, developing the model using fMRI data is not trivial. Generally, fMRI data has a very large feat...
