    "title": "The Role of Spatial Frequency in Cuteness Discrimination of  Infant Faces: An EEG Study",
    "subtitle": null,
    "abstract": "Infant facial cuteness serves as an evolutionary mechanism to enhance survival prospects by eliciting caregiving behaviors in adults. Spatial frequency (SF) processing is the basic mechanism for visual analysis. However, how different SFs contribute to the neural mechanisms underlying cuteness discrimination of infant faces remains poorly understood. To address this question, this study investigated how low SF (LSF) and high SF (HSF) differently modulate cuteness discrimination by behavioral accuracy measurement, event-related potential (ERP), time-frequency and functional connectivity analysis on recorded electroencephalogram (EEG) signals. Thirty participants performed a paired-comparison task in which they selected the cuter one face from two infant faces filtered with broad SF (BSF), LSF-only, or HSF-only. The behavioral results indicated that participants' cuteness discrimination ability in BSF condition was higher than that in LSF and HSF conditions. Time domain analysis revealed LSF faces elicited larger P1 amplitudes, while HSF faces evoked enhanced N170 and P300 components. Time-frequency and functional connectivity analyses further identified stronger theta-band oscillations and increased theta-band connectivity in posterior area when HSF faces were presented. These findings provide novel insights into the neural mechanisms underlying cuteness discrimination and highlight the importance of SFs integration in social face processing.",
