“…Emotional sensitivity can be defined as a lower threshold to respond to emotional stimuli, or a higher probability of experiencing stimuli as emotional [20]. Our previous study [21] showed that nursing students had a higher correlation between static FC coherence and behavioral accuracy in an affective task, as compared with a neutral task. Yet, brain connectivity is inherently dynamic, especially when involving task-evoked neural activities [22].…”

In this study, we proposed an analytical framework to identify dynamic task-based functional connectivity (FC) features as new biomarkers of emotional sensitivity in nursing students, by using a combination of unsupervised and supervised machine learning techniques. The dynamic FC was measured by functional Near-Infrared Spectroscopy (fNIRS), and computed using a sliding window correlation (SWC) analysis. A k-means clustering technique was applied to derive four recurring connectivity states. The states were characterized by both graph theory and semi-metric analysis. Occurrence probability and state transition were extracted as dynamic FC network features, and a Random Forest (RF) classifier was implemented to detect emotional sensitivity. The proposed method was trialled on 39 nursing students and 19 registered nurses during decisionmaking, where we assumed registered nurses have developed strategies to cope with emotional sensitivity. Emotional stimuli were selected from International Affective Digitized Sound System (IADS) database. Experiment results showed that registered nurses demonstrated single dominant connectivity state of taskrelevance, while nursing students displayed in two states and had higher level of task-irrelevant state connectivity. The results also showed that students were more susceptive to emotional stimuli, and the derived dynamic FC features provided a stronger discriminating power than heart rate variability (accuracy of 81.65% vs 71.03%) as biomarkers of emotional sensitivity. This work forms the first study to demonstrate the stability of fNIRS based dynamic FC states as a biomarker. In conclusion, the results support that the state distribution of dynamic FC could help reveal the differentiating factors between the nursing students and registered nurses during decision making, and it is anticipated that the biomarkers might be used as indicators when developing professional training related to emotional sensitivity.

“…fNIRS is widely used in clinical and scientific research. Based on existing neuroimaging studies, functional near-infrared spectroscopy appears to be a reliable neuroimaging measure for analyzing emotional states by examining changes in hemodynamic response in the prefrontal cortex (PFC) (Chong, Lu, and Tang, 2019).…”

The study aims to compile an overview of the empirical neuromarketing studies conducted in Turkish literature on the extent of neuroscience measurement methods. Within the scope of this study, which examines how measurement methods in the context of neuroscience have developed in the field of marketing between 2015 and 2022 in Turkey, solely empirical neuromarketing studies published in Web of Science(WOS), Google Scholar, Research Gate and Dergipark databases have been examined and the current situation in the field is evaluated in terms of neuroscience measurement processes. In this regard, the neuromarketing concept and the measurement tools used within this scope were explained first, and then the use of the measurement tools are examined and discussed on a literature basis.

“…fNIRS, klinik ve bilimsel araştırmalarda yaygın olarak kullanılmaktadır (Peng ve Hou, 2020). Mevcut nörogörüntüleme çalışmalarına dayanarak, işlevsel yakın kızılötesi spektroskopi, prefrontal kortekste (PFC) hemodinamik yanıttaki değişiklikleri inceleyerek duygusal durumları analiz etmede güvenilir nörogörüntüleme ölçümü olduğu görülmektedir (Chong, Lu ve Tang, 2019).…”

Turizm genellikle soyut kavramlar üzerine pazarlama faaliyetlerini gösteren bir endüstridir. Ancak geleneksel pazarlama araştırmaları tüketicilerin bilinç düzeyinde verdiği cevaplar üzerine kurgulanmakta ve bu durum yanıltıcı sonuçlar elde edilmesine neden olabilir. Nöropazarlama ise tüketicilerin genişletilmiş ve yüksek doğruluklu bir bakış açısıyla değerlendirilmesine olanak sağlar. Bu çalışmanın amacı turizm alanında nöropazarlama araştırmalarında bilişsel aktivitelerin ölçülmesine yönelik veri sağlayan Elektroensefelografi (EEG) ve fonksiyonel yakın kızıl ötesi spektroskopisi (fNIRS) yöntemlerinin uygulama alanlarını değerlendirilmesidir. Bu bağlamda nitel araştırma yöntemlerinden betimsel analiz yapılarak veriler raporlanmıştır. Araştırmanın sonuçlarına göre EEG ve fNIRS yöntemleri pazarlama çalışmalarında kullanım sayısı artış göstermekle beraber yüksek maliyet, zaman ve mekân gibi kısıtlarından dolayı turizm alanında son derece az tercih edilmektedir. Bununla birlikte turizm alanında yapılacak nöropazarlama çalışmalarındaki artış pazarlama faaliyetlerine ve tüketicilere geniş bir bakış açısı sağlayabilir.
