This study investigates possible differences of prefrontal cortex (PFC) activity as well as brain-to-brain coordination across PFCs of dyads during naturalistic social interaction from an attachment theory perspective by employing functional near-infrared spectroscopy (fNIRS) hyperscanning. Male participants with right-hand dominance (N=48) were administered Turkish Experiences in Close Relationship Scale (Sumer, 2006) for assessment of predominant adult attachment styles (Secure:27, Insecure: 21) and played regular and reverse cooperative and competitive versions of the rock-paper-scissors (RPS) game to facilitate standardized social interaction. By using a novel method, significant inter-brain coherence were observed for both competition and cooperation tasks at fronto-polar cortex (FC) and dorsolateral PFC (DLPFC) bilaterally in a lateralized manner depending on the task type. Moreover, two-sample t-tests have revealed that attachment styles do have effects on FC oxygenated hemoglobin (HbO) activation. Overall, our findings suggest that FC, thought as a hub for metacognition, while contributing to social interaction, interestingly elicits activation differences w.r.t. attachment styles as well, with secure attachment orientation exhibiting stronger hemodynamic response, which may serve as a putative neuro-biologic marker underlying individual differences.

Effects of Physical Manipulative Instructions with or without Explicit Metacognitive Questions on Geometrical Knowledge Acquisition
Ubuz, Behiye (2019-01-01)
In this study, effects of 2 physical manipulative instructions on students' geometrical knowledge acquisition were compared. Geometry topics' presentation was conducted via using physical manipulative and the practice stage in two different forms: (1) practice consisting of problems supported with explicit metacognitive questions and (2) practice consisting of problems not supported with explicit metacognitive questions. Participants were 220 6th grade students, studying in 5 classrooms. Students' knowledge...
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...
Effect of tense, aspect and aspectual class on event knowledge activation: a study with Turkish adults
Yöntem, Şevki; Temürcü, Ceyhan; Department of Cognitive Sciences (2015)
In this study we aimed to investigate effects of tense, aspect and lexical aspect on the activation of event knowledge. To this end, we conducted a short stimulus onset asynchrony (SOA) experiment, in which participants encountered a one-word sentence as a prime and reacted to a locational target word via speech. We analyzed response times with respect to aspect, tense and relatedness between prime and target words. Participants’ memory spans, measured by a backward digit span task, were also included in th...
Effects of inhibitory mechanisms and thought suppression tendency on the frequency and intensity of traumatic intrusions
Yarar, Orhan Ferhat; Gençöz, Faruk; Mısırlısoy, Mine; Department of Psychology (2011)
The present study investigates the effects of cognitive inhibitory mechanisms and tendency to suppress thoughts on the frequency and intensity of traumatic intrusions within the trauma film paradigm. Non clinical participants’ response inhibition and proactive inhibition levels and tendency to suppress thoughts were measured prior to exposure to a trauma film. One week after seeing the trauma film, participants reported the frequency and intensity of trauma film related intrusions with an intrusion diary an...
