    Evaluating Electrophysiological Responses Due To Identity Judgments
    (Ieee, 2024) Çakar, Tuna; Hohenberger, Annette
    This study was conducted to explore how the brain processes decisions about identity, employing event-related potentials (ERPs) as a measure. The aim was to ascertain if the EEG/ERP technique could be used to monitor the cognitive processing of identity judgments as they happen. The investigation focused on comparing two groups of statements: those that used the concept of 'same' and those that used 'different'. The researchers hypothesized that there would be notable differences in the ERPs, particularly around the 400-millisecond mark, correlating with the reaction time disparities observed behaviorally. The ERP data revealed that the 'different' statements generated a unique N400 response when contrasted with the 'same' statements, implying that the participants' cognitive responses to these two types of judgments were not the same.

    Neural Correlates of Identity Judgments in the Prefrontal Cortex: an Optical Brain Imaging (fnirs) Study
    (IEEE, 2023) Çakar, Tuna; Hohenberger, Annette
    The prefrontal cortex (PFC) plays a crucial role in human reasoning and decision-making. Studies using neuroimaging techniques have shown that situations involving conflicts lead to increased activity in both the prefrontal cortex and the anterior cingulate cortex (ACC). This research specifically investigates the activity in the prefrontal cortex when individuals assess statements related to identity. The results obtained through optical brain imaging (fNIRS) indicate that participants experience greater conflict when evaluating propositions they strongly disagree with, compared to propositions they strongly agree with. Furthermore, responses that are indeterminate lead to higher activation levels in prefrontal regions. Additionally, the analysis of the participants' reaction times reveals significant differences associated with the content of their responses.
